Title: Swash plate type compressor
Inventor: HATSUTORI MITSUHIRO
IPC: F04B39/00
Filed: 1980-09-09
Abstract: PURPOSE: To prevent seizure of sliding elements for transmitting the driving force of a swash plate to a piston even if the lubricating conditions are severe, by shaping the flat part of the substantially spherical sliding elements to have a slightly convex curvature.  
     CONSTITUTION: In a swash plate type compressor shown in the Fig, a flat portion 10b of each spherical sliding element 10 is shaped to have a slightly convex, smoothly curved surface 10c having an extremely large radius of curvature, so that the height H 1  is less than 15μm. Since, with such an arrangement, a wedge-shaped clearance, having an extremely small wedge angle that is decreased gradually in a smooth manner, is formed between the curved surface 10c of the sliding element 10 and the surface of a swash plate 8, lubricating oil attached to the surface of the swash plate 8 is readily drawn into the clearance at the time of high-speed operation, so that a film of lubricating oil for preventing direct contact between them is formed. Further, since the contact point of the swash plate 8 and curved surface 10c is changed for each rotation along with swinging motion of the sliding elements 10 and the amount of lubricating oil circulated is increased resultantly, so that the lubricating conditions can be further improved. Thus, it is enabled to protect the sliding elements 10 against seizure.

Title: Emergency call system
Inventor: KASAI SHIGERU
IPC: H04Q1/28
Filed: 1979-09-28
Abstract: PURPOSE:To enable a call from a maintenance station during an electric power failure at an unattended exchange by calling an unattended station on the no- power-source system and by supplying a calling circuit from the maintenance station. CONSTITUTION:When unattended station SO is in a power failure, calling-signal receiving bell BEL is connected to stand-by talking circuit Ts and communication calling handset TR is connected to stand-by talking circuit Ts to hold calling-current supply from maintenance station TC in readiness. Then when connection key ON and calling key R1 is maintenance station TC are operated, a calling signal of 16Hz is sent to unattended station SO to put BEL into operation, letting a patrolling inspector know incoming. Next, the patrolling inspector operates answer key ANS to supply a calling current from maintenance station TC to handset TR, permitting a communication call. Thus, the communication call can be made even in a power failure at the unattended station.

Abstract: PURPOSE: To determine the contour of tantalum by etching by constituting each heating element of the high temp. pyrolytic silicon nitride layer deposited on a resistance layer in predetermined thickness and the cavitation stress protecting layer deposited thereon. CONSTITUTION: A pyrolytic silicon nitride layer 17 is directly deposited on an exposed polysilicon heating element in a thickness of about 1500 Å and, succeedingly, a tantalum layer 12 with a thickness of 0.1-1.0 μm is deposited thereon in order to protect the pyrolytic silicon nitride layer 17 from cavitation stress. The pyrolytic silicon nitride is deposited by reacting ammonia (NH3 ) and dichlorosilane (SiCl2 H2 ) at about 800 deg.C. Since the pyrolytic silicon nitride is slowly etched by a mixed soln. of a caustic alkali soln. conc. at high temp. and HF/HNOH3 , Ta can be subjected to wet etching. Thereafter, Ta functions as a mask for determining wet or plasma etching of pyrolytic Si3 N4 in boiled phosphoric acid.

Title: Antilock brake controller
Inventor: TSUTSUMI JUNJI
IPC: B60T8/66
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To quicken pressure reduction timing at the time of antilock brake control in a high liquid pressure brake mechanism so as to prevent the fluctuation of deceleration when a vehicle runs on a road surface having high coefficient of friction. SOLUTION: A wheel speed detection value Vwi (i=FL, FR, R) of a wheel to be controlled is detected, and wheel acceleration Vwi ' and a ground speed VIG are calculated based on the detected value. When a road surface has a high coefficient of friction and the number of pressure increase production NZ is above a set value NS after the second control cycle, target wheel speed VW* is changed from a normal value (for example, 90% of the ground speed VIG) into the direction in which wheel slip is reduced to quicken pressure reduction timing and suppress a pressure reduction amount in a high hydraulic pressure brake mechanism to a proper value so as to prevent the fluctuation of deceleration. After that, when the wheel acceleration Vwi ' exceeds a positive threshold value γ2 , it is returned to the normal value to avoid the delay of the pressure increase production timing.
