Title: Brake device
Inventor: INEO TAKESHI
IPC: F16D57/06
Filed: 1987-11-05
Abstract: PURPOSE:To apply brake smoothly and to enable accurate stoppage at a predetermined position by arranging a switching valve to a sub-path having high flow resistance in the way of a main oil circulation path of a hydraulic pump which rotates as a movable member moves. CONSTITUTION:Upon movement of a movable member 1, a rotary body 6 rotates to drive a hydraulic pump 8. If a changeover valve 13 is switched to a main path 10 side at this time, oil delivered from the hydraulic pump 8 passes through the main path 10 and returns back to the suction port of the hydraulic pump 8, and thereby the hydraulic pump 8 and the rotary body 6 rotates with low resistance this applying brake scarcely onto the movable body 1. Upon switching of the changeover valve 13 to a sub-path 11 side, oil delivered from the hydraulic pump 8 passes through the sub-path 11 having high flow resistance and suppress rotation of the hydraulic pump 8 and the rotary body 6. Consequently, the movable body is braked and stopped subsequently. In such a manner, movable body can be stopped accurately at a predetermined stopping position through braking at the movable body side.

Title: Parity circuit
Inventor: NAKAJIMA KATSUTO
IPC: H03M13/00
Filed: 1989-10-27
Abstract: PURPOSE:To make correspondence to the number of bits in an arbitrary data bit and to reduce man-hour for design by executing cascade connection to a deciding means, which is composed of a holding means to hold one bit of input data and a selecting output means, to an input in the next step. CONSTITUTION:A deciding means 9 is composed of a latch 1 to hold one bit of the input data and a selecting output means 2 to turn a first input 3 as a first output 8 while not-inverting or inverting the input corresponding to the output of the latch 1. The cascade connection is executed for the means 9 so that the number of bits in the input data and the output 8 can be connected to the input 3 in the next step. Thus, in the case of an even-number parity, when the total sum of '1' in the data bit is an even number, '0' is outputted as a parity bit and when it is an odd-number '1' is outputted as the parity bit. Similarly, in the case of an odd-number parity, the parity bit can be obtained by setting the input 3 in the initial step to '1'. Thus, since the parity circuit of regular circuit configuration can be constituted, the correspondence can be made to the number of bits in the arbitrary data bit and the man-hour for design can be reduced.

The advance and reverse clutches 6 are cut off by power of an engine 1, and the power is not transferred to right and left driving wheels 5L, 5R. Since a vehicle is not started with crawling travel, it is possible to prevent creep.

Filed: 1987-11-06
Abstract: PURPOSE: To make the passage resistance of a refrigerant flowing in a heat accumulator uniform and improve a heat exchanging efficiency by making the void ratio of the buffer space side of the heat accumulator higher than that of an expansion space and sequentially combining materials high in their specific heat and thermal conductivity in respective temperature zones. CONSTITUTION: A heat storage material 15 is formed with a nickel wire gauze 18 and a copper wire gauze 20 in its buffer space 11 side in the order of high specific heat. The expansion space 12 side thereof is formed with a tungsten wire gauze 19. The number of meshes of the wire gauze of the buffer space 11 side is smaller than that of the expansion space 12 side to enlarge clearances. The heat storage material 15 for precooling working refrigerant for cooling a load heat exchanger 17 to cryogenic temperature serves to make the passage resistance of the working refrigerant uniform even when the temperature of working refrigerant flowing in a displacer 10 becomes low from the buffer space 11 side to the expansion space 12 side and the specific volume thereof is reduced. Thus, uniform heat exchanging efficiency is obtained in respective passages.

Title: Manufacture of semiconductor device
Inventor: NODA MASANORI
IPC: H01L21/31
Filed: 1984-12-31
Abstract: PURPOSE:To reduce the number of processes by providing a process, in which an insulating film formed on the back side of a semiconductor substrate is removed, after a process in which the insulating film is formed to the substrate. CONSTITUTION:Insulating films 2 are shaped onto a semiconductor such as a silicon substrate 1. The insulating film 2 on the back side of the substrate 1 in the insulating films 2 is removed to expose the substrate 1, and polysilicon is grown. Consequently, a film 3 for a gate consisting of polysilicon is wired onto the insulating film 2. A polysilicon film 4 directly grows on the back side of the substrate 1, and applied stress to the substrate 1. A process in which an impurity is diffused is conducted in order to give the film 3 conductivity. Heavy metals, such as molybdenum, tungsten, etc. made to be contained in the substrate 1 are captured to a defective region formed on the basis of stress and strain generated due to the formation of SiP, etc. in the substrate 1 through heat treatment. As a result, double gettering effects are acquired through the growth of the polycrystalline semiconductor and the diffusion of the impurity. Accordingly, a gettering exclusive process is unnecessitated only by adding one process in which the insulating film on the back side of the semiconductor substrate is removed.
