Title: Carrier container
Inventor: HOSHINO NORIO
IPC: B65D85/50
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To efficiently carry stored items of different heights, by disposing projections and recesses, into which the projections are fittable, in the area where openings are joined facing each other in order to make an empty space in which the items to be stored can be put. SOLUTION: The side walls 1 form at their upper ends flanges 3, each consisting of horizontal position 3' and vertical portion 3", in the same length so as to surround an opening. Each flange 3 is provided with a projection 4 formed on the horizontal portion 3', and a recess 5, adjacent to the projection 4, into which the projection 4 is fittable. The projection 4 and the recess 5 are provided in symmetrical positions with respect to the vertical center line of each side wall 1. After items to be stored are put into one carrier container, other carrier container which is empty is put over it so that their openings face each other. Each projection 4 fits into the corresponding recess 5, therefore the upper carrier container is stably placed over the lower carrier container without lateral displacement.  Properly combining several kinds of carrier containers of different heights makes it possible to cope with items to be stored which are different in height.

Title: Electromagnetic wave shield material and clothing using it
Inventor: ISHIHARA KEN
IPC: A41D31/00
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To efficiently show the shielding effect of an electromagnetic wave by overlapping at least two knitting fabrics made of conductive fiber while a stitch is shifted. SOLUTION: At least two knitting fabrics are overlapped while a stitch is shifted. More specifically, the knitting fabrics are shifted up and down, and are preferably overlapped so that courses cross orthogonally. For three types, namely 'parallel/parallel', 'parallel/cross', and 'cross', a result where a magnetic field shield ratio is measured by the KEC method is showen in a figure. As shown in the figure, in the case of 'parallel/cross', shield efficiency is excellent. On the other hand, in the case of 'cross', the shield efficiency is nearly the same or slightly lower than the case of 'parallel/parallel'. Therefore, when the woven texture is created by the minimum amount of conductive fiber according to a target, electronic waves can be shielded effectively with this kind of configuration.
