Abstract: PURPOSE:To pivot a suspension member into a direction in which a turning radius is increased and improve the stability in steering by a method wherein an elastic body, capable of moving both ends of the fore and rear suspension members into reverse directions mutually upon turning, is provided in the device. CONSTITUTION:Upon turning of a vehicle, a roll, sinking the outside of the body of the car and floating the inside thereof, is generated and the outside of the member 3 in turning is moved downwardly with respect to the body by the relilient force of the elastic body 20 while the inside thereof is moved upwardly. At this moment, the outer tube 22 of the outside elastic body 20a is moved downwardly with respect to the inner tube 21 in accordance with the movement of the member 3, therefore, the rubber 23 deforms into the shearing direction in accordance with the relative movement between the inner and outer tubes 21, 22 and the fore side thereof deforms by a compression while the rear side thereof deforms by the tension. As a result, the outer tube 22 is moved forwardly while the same tube 22 of the elastic body 20b is moved rearwardly because the compression and tension deformations of the elastic body 20b becomes reverse to the same body 20a, therefore, the member 3 pivoted to the right upon the right turning of the car as shown by a chain line. Accordingly, an arm 2 and a wheel D are pivoted together with the member 3 in the feeling of under-steering and the steering may be stabilized.

Title: Semiconductor device
Inventor: IKUMA HIDETAKA
IPC: H01L21/52
Filed: 1977-10-14
Abstract: PURPOSE: To obtain a semiconductor device which excels in the heat radiation effect by enhancing the mounting performance of the semiconductor element.  
     CONSTITUTION: Lead-tin group solder 3 is welded to copper heat sink 1 in the H 2  atmosphere. The oxide on the surface of the copper and solder is removed to give Ni plating 2 of 3W10μm. When element 4 is mounted on the heat sink, plating film 2 enters solder layer 3 to eliminate the effect of the gas produced from the Ni plating. At the same time, the oxidation is avoided by the Ni film on the solder surface, so the solder and the element can be sticked together well. Thus, the oxide product is reduced with a uniform solder layer formed, ensuring an easy fixture between the element and the heat sink

Title: Memory dump control system
Inventor: FUKAURA YOSHIAKI
IPC: G06F11/34
Filed: 1989-05-17
Abstract: PURPOSE:To execute a dumping process with a simple device constitution without causing any operational error by allowing a user to execute the dumping process successively followed by the restarting of data processing by operating one resetting switch only. CONSTITUTION:When a user operates one reset switching means 40 only, he can dump the information dumped in a memory section 13 in an external storage device 30 and, at the same time, restart data processing. In addition, even when the user wrongly presses the switching means 40 successively, no wrong operation is executed, because a resetting operation detecting section 11 does not inform a memory data processing section 16 of the second actuation of resetting operation when a flag is set in a resetting flag area 15. Therefore, a dumping process can be executed with a simple device constitution without causing any operational error.
