Results of Comparative Test of Child Safety Seats

    In Japan, the usage of child safety seats when driving with a child in
the car is extremely low, compared to the use of adult seat belts. (The rate
of use is only 7.7% according to the Japan Automobile Federation (JAF)).  We
tested 6 brands of child safety seat sold by 6 companies intended for use by
small children between the ages of 4 months and 4 years, and priced between 
 26,800[Yen] and  29,900[Yen].






[Safety]

    Crash tests simulating a 50km/h head-on crash showed that there was no
problem in the failure strength of the buckle, the amount of shock and the
amount the dummy moved immediately after the impact.  However, in the case
of one brand, the structure of the child safety seat is such that the back
plate opens up under impact, the back plate opened up and pressed into the
back of the dummy.  Furthermore, the belt remained tensely stretched out, 
which made the buckle difficult to undo.
    With another brand, the metal fitting to insert into the chest guard
deformed under impact, and became exposed.  However, this had no effect on
the (dummy) child.  With two other brands, the buckle's insertion fittings
deformed somewhat.

[Performance]

    All six brands had a cushion material for the back and especially for 
the head in order to soften the shock.  However, there was a difference in
the size (scope) and thickness.  Our test assumed a head-on crash, and so we
could not investigate the effects of differences in the thickness of the
cushion material. 
    The seat back, which is supposed to hold the child while riding in the
car, was sufficiently large in all brands.
    As for the material for the seat cover, there was some difference in
terms of durability, strength of dyed color, and so forth.

[Usability, labeling, etc.]

    The monitors evaluated that the brand that was heavy with a rounded 
bottom was hard to carry, tended to become unstable, and was difficult to 
install.
    In response to the enforcement of the Product Liability Law, the makers 
have added more labels for danger, warnings, prohibitions, precautions, 
etc., both in words and graphic illustrations.  However, because these
cautions were written in various places in the handling instructions, they
were often difficult to understand.

Points to remember when making a purchase Precautions on usage

Results of Product Test for Air Cleaner

   In Japan, huge quantities of cedar pollen blanket the country between 
March and May of each year, the season of pollinosis (pollen allergy).  More
and more people are wanting to remove all the dust, pollen and other allergic 
substances, as well as odor, that float in the room.  Air cleaner is therefore
 attracting great interest now.  However, consumer information centers in a 
number of communities have been receiving complaints such as "the air 
cleaner that I bought doesn't work at all," and so forth.  We therefore 
tested 7 brands of air cleaner sold by 6 companies, both the forced 
circulation type (equipped with a fan) and the non-forced circulation type, 
for their ability to collect dust, remove odor, etc.

[Performance]

    We tested the equipment's ability to collect dust and remove the odor of
burning cigarette smoke.  We found that there were significant differences
among brands of the forced circulation type.  With the non-forced circulation 
type, the equipment simply removed dust from the area gradually, and the
performance was far lower that of the forced circulation type.  Thus, 
consumers cannot expect practical results from the non-forced circulation 
type in very dusty or contaminated places.  Next, we investigated the 
removal of ammonia gas, which is the main component of the offensive odor of
cigarettes.  The non-forced circulation type brands had no appreciable
effect.  As for the forced circulation types, while there were some 
differences among the brands, some brands were effective in removing the
odor.  However, even these could not remove the odor to the point where the 
order could not be detected.

[Safety]

    We investigated the generation of ozone because when there is a high
concentration of ozone, it can damage the human body, especially the
breathing organs.  All the brands generated a small quantity of ozone, but
the concentration within the room was a very small quantity in all cases, 
which is not sufficient to have an adverse impact on the human body.

[Labeling]

    Each brand had information on the label concerning the applicable room
area, but the actual performance of nearly all of the brands tested was 
inadequate for the indicated room area.  In particular, the non-forced
circulation brands were not adequate even for a 6-tatami room (one tatami 
normally measures about 90×180cm, or 1.62 square meters).  The performance
of this type is thus far below the indicated amount.  Also, with regard to
the dust collection and odor-removing capabilities, the information in the
catalog was frequently misleading for consumers.

[Advice to consumers]

    When you purchase an air cleaner, choose the type carefully, because
there are large differences in the performance depending upon the type as 
well as the brand.  In making your selection, use the results of this test
as a guideline, and choose the type which meets your specific needs.  Also, 
in terms of cautions in using the equipment, the air cleaner that we tested 
could not remove gas emitted from an open stove; the filter should be 
changed frequently, and be aware that the area around the air cleaners to 
get more dirty.  Take care of these points. 

Report on Meal Delivery Service for Elderly Persons
- Outline of the Service and Results of Questionnaire to Users

    Japanese society is graying at an unprecedented rate.  As of May 1995,
therewere 18,210,000 persons above 65 years of age, or 14.5% of the 
population.  By households, the number of elderly persons living alone and
the number of households consisting of only an elderly couple are 
increasing. 
    Public services for the elderly must urgently be upgraded, and such 
services in the private sector must be developed, both in quantity and
quality.  The meal delivery services for the elderly (hereafter called
 "meal delivery service" ) which we investigated this time are one type of 
such service, and the demand for this kind of service is expected to
increase in the coming years. 
    Meal delivery services fall into the following three categories: (1) A
service provided by a business enterprise in the private sector for profit, 
(2) a service provided for welfare purposes, by local governments and 
nonprofit groups established to carry out welfare work, and (3) a service 
which is run with the aim of mutual aid by consumer cooperatives and/or 
volunteer groups. 
    The purpose of all of these meal delivery services is to support the
daily living of elderly persons who have difficulties in cooking.  In 
addition, the services in categories (2) and (3) seek to ease the sense of
isolation of the elderly. 
The services provided by 8 companies in the private sector are as follows:
