Title: Rack and pinion steering system
Inventor: KITAHATA KOJI
IPC: B62D3/12
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of chattering sound of teeth between a pinion of a pinion shaft and a rack of a rack shaft by composing a support yoke for supporting the rack shaft, of magnesium or a magnesium alloy. SOLUTION: A body of a support yoke 3 is made of magnesium or a magnesium alloy, and the linear expansion coefficient of magnesium is 2.6×10-51/ deg.C to be the same degree as 2.2×10-51/ deg.C of aluminum which is the material of a housing 4. A clearance between the support yoke 3 and a support yoke storage hole 4a is made small to store the support yoke 3 in the support yoke storage hole 4a. As a result, a rack shaft 2 is positively supported by the support yoke 3 so as to suppress the generation of chattering sound of teeth caused by clapping between a pinion 1a and a rack 2a even in the case of vibration being transmitted from a steered wheel to the rack shaft 2 during travel of an automobile.

Title: Push button device and portable telephone radio
Inventor: IMAZAKI KAZUNORI
IPC: H01H13/14
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a push button device and a portable telephone radio that can be miniaturized while restraining an erroneous operation caused by pushing adjacent buttons at the same time. SOLUTION: Because a transmission button 15, a retransmission button 16 and a finish button 17 are arranged in a form adjacent to and abutting on one another, the total occupying area of the transmission button 15, the retransmission button 16 and the finish button 17 is reduced even if the occupying area of each of the buttons is not reduced. Additionally, since the depression pressure required for the operation of one of the adjacent push buttons is one and a half times as much as that of the other, the adjacent buttons can be distinguished by the sense of touch and an erroneous operation caused by pushing the adjacent push buttons at the same time can be restrained.

IPC: B29C51/26
Filed: 1988-12-15
Abstract: PURPOSE:To reduce the degree of ununiform thickness by a method wherein the members of a plug consisting of a plurality of layers of cylindrical members, which are provided around a bar-like center member and slidable each other, are projected in order starting from the center member into a vacuum forming mold so as to bring a sheet close to the inner surface of the vacuum forming mold in order to vacuum-form the sheet. CONSTITUTION:A thermoplastic resin sheet 7 having an oxygen barrier layer is attached to the opening of a mold 1 with a fixture 8. The sheet is heated up to the predetermined temperature and, after that, a center member 3 is projected. In this case, the portion contacting with the upper edge of the mold of the sheet is pushed up by means of air in the interior of the mold and stretched more than its portion fixed to the fixture 8. Next, cylindrical members 4 and 5 are projected in order, resulting in uniformly stretching the sheet 7 in order with the respective members 3, 4 and 5 of a plug 6 so as to bring the sheet to the state close to the inner surface of the mold 1. When the mold is vaccumized through a pipe 2 at this time point, the sheet 7 is brought into close contact with the inner surface. A vacuum- formed vessel 9 is obtained by being released from the mold. Since the vessel 9 is stretched gradually with the respective members 3, 4 and 5 so as to be brought close to the inner wall of the mold 1 for the final vacuum forming, the degree of ununiform thickness of the vessel becomes small.
