Title: Relay valve for air brake
Inventor: FUKUOKA NOBUO
IPC: B60T15/18
Filed: 1982-01-31
Abstract: PURPOSE:To prevent the abnormal braking force in transition by setting the ratio between the area of an air supply passage from an air tank and that of an air supply passage to a power cylinder within a fixed range. CONSTITUTION:A ratio between an area S1 of an air supply passage 12 from an air tank and an area S2 of an air supply passage 13 to a power cylinder 13, S2/S1, is set within a range between 0.1 and 0.4. In this constuction, air is introduced from a brake valve into an introduction pipe 2 by the operation of a brake, and a piston 4 is pushed down to intercept the connection between chambers C and D, which a chamber E is connected to the chamber D for supplying air from the chamber E to the chamber D via an introduction pipe 6 and a passage 12. The air is sent to a power cylinder from the chamber D via a passage 13 and an air pipe 11. At this stage, since the ratio of area between passages 12 and 13 is set within the set value, even a hard braking operation cannot cause an abnormal braking force in transition.

Filed: 1982-01-29
Abstract: PURPOSE:To improve the bondability as well as to prevent the contamination of an electric torch electrode and a capillary of the titled device by a method wherein the ball is formed in the atmosphere of gas which blows out of a nozzle. CONSTITUTION:N2 is blown out at all times or when the ball is being formed into the space between the capillary 2 and the electric torch electrode 13 from the nozzle 12 through a tube 15 and a pipe 11, a high voltage current is applied to the electric torch electrode 13, and the ball 3a is formed by the spark generated between the point of a wire 3 and the electric torch electrode 13. The flowing quantity of said N2 gas changes a little according to the diameter of the wire 3, but 2-4l/min or thereabout is considered to be suitable. As the ball 3a is formed by blowing inert gas as above and by generating sparks in the gaseous atmosphere, the ball can be formed without inflicting the effect of the oxygen, vapor, dust, ozone and the like contained in the air, thereby enabling to improve the bondability and to prevent the contamination of the electric torch electrode 13 and the capillary 2.

Title: Disk performing method
Inventor: KUROHARA HIDEO
IPC: G11B7/005
Filed: 1995-02-01
Abstract: PURPOSE: To instantly restart the performance from a performance position where ACC is turned off when the ACC is turned on after it was once turned off. CONSTITUTION: When the ACC off is detected during the performing time, a system controller 17 stores a performance address of the point of time in an incorporated RAM 17A, and thereafter, when the ACC on is detected, the controller 17 searches the stored performance address, and restarts the performance of a mini-disk 1. When the compressed musical data are stored in a DRAM by a fixed amount, after the controller 17 stored a read-out address from the mini-disk 1, it interrupts the read-out of the compressed musical data from the mini-disk 1 while continuing the read-out of the compressed musical data from the DRAM 9, and it reads out TOC information (UTOC information) to store it in a prescribed area of the DRAM 9. Then, it searches the stored read-out address to restart the read-out of the compressed musical data from the mini-disk 1 after completion of searching.

Title: Deciding system for working or spare state
Inventor: MASUDA HIROKI
IPC: H04Q3/545
Filed: 1986-01-27
Abstract: PURPOSE:To fix both working and spare central control units CP with a duplexed CPU by securing a time difference between the application of a power supply and the transmission of the start signal received from each start time limit part. CONSTITUTION:A connection terminal 39a is connected in a CPU 3a and a connection terminal 39b is cut off in a CPU 3b respectively. When the power supply voltage V0 is applied, the input voltage V1a has a sudden rise compared with the input voltage V1b. Thus a gate A in a power supply application circuit 31a can set the output voltage V2a to a high level from a low level in a short time compared with a gate A in a power supply application circuit 31b. Therefore the start signal (ra) is outputted from the circuit 31a earlier than the circuit 31b. Thus the signals Sa and Sb are set in a using state and a spare state respectively.

IPC: F04B27/10
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce noise generated from a thrust bearing, and achieve calm operation by providing a slide bearing as the thrust bearing between a lug plate and a inner surface of a housing. SOLUTION: A thrust bearing 50 is formed between an inner surface of a front housing 22 and a front surface of a Jug plate 35. A swash plate 39 thus receives gas pressure of a cylinder bore 30 to receive axial direction force from the right side to the left side for supporting the force in the same direction applied to the Jug plate 35. This thrust bearing 50 is composed of a semi- spherical bearing element 51 of which spherical surface part is fitted with a spherically recessed holding part formed in an inner surface of a front housing 22 to be supported. A radius of a spherical surface part of the holding part is set to be only a little larger than a radius of a spherical surface of the bearing element 51, so the bearing element 51 is slidably engaged in the holding part, and that lubricating oil can be easily taken in.  Slide characteristics can thus be improved to provide calm operation.
