Title: Electrode structure for display device
Inventor: SHIRATORI TETSUYA
IPC: H01J29/46
Filed: 1987-04-07
Abstract: PURPOSE:To apply the same potential as a metal back to all bar-shaped support means and display a high-quality image by using a conductive material for the bar-shaped support means fixing material and connecting the conductive materials with a conductive substance. CONSTITUTION:A support wall 14 is located between a mount plate 13 and a metal back 3, support means 20 made of a conductive material are brought into contact with the metal back 3 at one end and are integrated with the support wall 14 and a fixing plate 21 at the other end by a fixing agent 22. A conductive material 31 is used for the fixing agent 22, or a conductive substance 41 is used for part of the surface, thus the support means 20 are stuck and fixed, and simultaneously the support means 20 are made conductive with a metal film 24. The adjoining support means 20 are made conductive with each other by the metal film 24 via the fixing agent 22. The end section of the film 24 and the metal back end section 3a are made conductive by a conductive means 25, thereby all bar-shaped support means 20 can be kept at the same potential as the metal back 3.

Title: Rotary shaft coupling
Inventor: IWAO KEIJIRO
IPC: F16F15/20
Filed: 1991-04-17
Abstract: PURPOSE:To improve the balancing accuracy of a rotary system including a rotary shaft coupling. CONSTITUTION:A mass-body 7 is shifted from two central axes of rotation consisting of the central axis of rotation of an input rotary shaft 10 and a cross-shaft 4 so as to be mounted to the yoke 2 of a Cardan joint 1, and a mass-body 8 is mounted to a yoke 3 at a position symmetrical to the mass-body 7 by holding the center of the cross-shaft 4 therebetween. When a rotating system is rotated, the yokes 2 and 3 are pulled in opposite directions by centrifugal forces generated a the mass-bodies 7 and 8, and thus the direction and the magnitude of relative displacement generated between the yokes 2 and 3 due to looseness component of bearings 5, 6 are univocally determined. After balancing is applied to the whole rotating system, the amount of unbalance contained in the Cardan joint is changed not to make the balancing meaningless.

Title: Air bag against side collision
Inventor: OKOCHI TSUTOMU
IPC: B60R21/2338
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To certainly expand an air bag between a narrow space between a vehicle body and an occupant on a seat without exerting excess impact to the occupant. SOLUTION: A bag 7 is formed from the main body 9 facing to the abdomen 8, and the upper expanding portion 11 facing to a breast 10 of an occupant 6. The upper expanding portion 11 is undercut at the edge portion to decrease its length, while the portion of a gas inlet 14 to be connected to the inflator 5 is shorten, so that the length of the upper expanding portion 11 is shorten as compared with the length of the main body 9. Accordingly, when the bag 7 is expanded, the width of the upper expanding portion 11 will become smaller than that of the main body 9, permitting the bag 7 to be surely expanded into a narrow space between a vehicle body and the occupant 6, thereby over impact will not exert to the breast 10 of the occupant 6.

Title: Improvement of plasticity of kaolin clay
Inventor: TSUNEMATSU KINUE
IPC: C04B33/04
Filed: 1990-03-30
Abstract: PURPOSE:To obtain kaolin clay having superior plasticity as pottery raw material by adding proper amounts of urea to kaolin clay and carrying out dry grinding and wet grinding. CONSTITUTION:Urea is added by 5-10wt.% to kaolin clay raw material, and these are mixed and then subjected to dry grinding by a mechanical mortar for about 1hr. Subsequently, the resulting mixture is subjected to wet grinding by means of a pot mill. By this method, the kaolin clay can be formed into thin layer by a simplified operation to improve plasticity, by which the kaolin clay can be made applicable to pottery raw material. The reason why dry grinding is exerted at this time is that, if wet grinding alone is exerted, the degree of reduction in specific surface area becomes greater than in the case without grinding. Moreover, the added urea can be practically washed away by means of subsequent wet grinding and hot water rinsing, and even if it remains by a small quantity, it can be scattered at the time of burning as pottery.
