Patent JP-S5920757-A (JP)
Title: Deceleration sensitive type hydraulic control valve
Inventor: KUBOTA HITOSHI
IPC: B60T8/28
Filed: 1982-07-27
Abstract: PURPOSE:To compensate the delay of response of a deceleration responding valve, by providing a pressure difference valve responsive to the pressure increase speed of inlet hydraulic pressure between the deceleration responding valve and a confining chamber. CONSTITUTION:A pressure liquid from a master cylinder 36 is led via a chamber 33, an orifice 25a, and a chamber 31 into a control valve CV, and the pressure thereof is proportionally decreased and is transmitted to a rear wheel brake. On the other hand, the pressure liquid passed through the deceleration responding valve GV reaches the confining chamber 10a via the pressure difference valve DV to control the pressing force of a spring 15. The pressure difference valve DV is pressed by an actuator 25 arranged to the orifice 25a through a spring 27, and thus the working pressure of the difference pressure valve can response to the speed of increase in the inlet hydraulic pressure. If the deceleration of the vehicle is behind the increase in the hydraulic pressure due to abrupt braking, the confining pressure can be precisely controlled and therefore the control of turning point becomes accurate.

Title: Device for attaching, detaching and fixing die
Inventor: ITOU NOBORU
IPC: B21D37/14
Filed: 1983-07-20
Abstract: PURPOSE:To make die exchange quick and easy in attaching, detaching and fixing the die to and from a die base plate by installing a guide for fixing and supporting the die to one end of the die base plate and a spring-energized wedging pawl to be rollably moved by a lever operation on the opposite side. CONSTITUTION:A die H is fixed to a die base plate 1 by means of a guide 12 for supporting the end part of said plate and a wedging pawl 2 which is energized by a spring 6 and is pressed to the pawl 2b of a cam for operating the stationary pawl. When a lever 11 is operated in the direction U, the operating cam 4 moves to the right and pushes the pawl 2b with the projecting part 4b, then the pawl 2 falls around a shaft 3 and sinks into recesses 1a, 4a. The die H is therefore easily taken out. The installation is accomplished by the operation reverse from the above. The installation and exchange of the die are extremely easily and quickly performed by the above-mentioned procedure.

Title: Track accessing method for optical information recording medium and optical information recording and reproducing device
Inventor: MIZUHATA SHINJI
IPC: G11B21/08
Filed: 1993-06-02
Abstract: PURPOSE:To perform accurate track access by moving a light beam by different quantity between movement quantity calculated based on the number of cross counted by a count step and the prescribed movement quantity by a coarse movement step in a movement step. CONSTITUTION:A TADD is compared with a prescribed threshold level A in a track count 1c 27, and a binary ON track signal (DTADD) is generated. The track count circuit 27 performs count up (or count down) depending on variation of TES for each track crossing making the direction of access the normal direction, while compensates a count value by performing count down (or count up) depending on variation of TES when an optical head is moved to the reverse direction for the direction of access. Thereby, even if the moving direction is changed in moving owing to disturbance and the like, the accurate track count can be performed.

Abstract: PURPOSE:To select and receive an optional sound out of plural sounds corresponding to an image by selecting an optional cell from plural cells included in a sound signal by a sound cell selecting part and converting the output cell into a sound input signal to be inputted to a TV image receiver. CONSTITUTION:When an image signal 4 is inputted to the input of a video cell assembling part l, an image cell 6 is outputted. When individual monophonic sound signals 5-1 to 5-3 are respectively inputted to the inputs of sound cell assembling parts 2-1 to 2-3, sound cells 7-1 to 7-3 are outputted. A cell multiplexing part 3 multiplexes these cells and outputs an output 8 to a wide band ISDN.

Title: Radiation temperature measuring instrument
Inventor: HISHIKARI ISAO
IPC: G01J5/08
Filed: 1986-06-06
Abstract: PURPOSE:To easily obtain an accurate measured value by finding the temperature of an object of measurement from the ratio of a detection signal by the projection by light sources at plural angles upon a position normal to the measurement position of the object of measurement and a detection signal in the absence of the projection signals. CONSTITUTION:A light source 21 projects light upon the normal l to the measurement position P of the object 1 of measurement at an angle theta1 and a light source 22 projects light at an angle theta2; and a detector 3 performs photodetection at an angle theta0. The light sources 21 and 22 are controlled to turn on and off by turning on and off a power source E through switch devices S1 and S2. When there is light from neither of the light sources 21 and 22, light from a light source 2 is photodetected by the detector 3. Therefore, the temperature of the object of measurement is corrected and found from the ratio of the detection signal based upon projection signals from the light sources 21 and 22 and the detection signal in the absence of the projection signals from both light sources.

Title: Pump nozzle of internal combustion engine
Inventor: SAITOU ATSUSHI
IPC: F02M63/02
Filed: 1982-07-26
Abstract: PURPOSE:To improve the injection characteristic and simplify the internal construction by assuring reliable operation of a solenoid valve and placing a change-over valve and the solenoid valve in the coaxial and adjacent arrangement. CONSTITUTION:When a solenoid valve 5 is lifted upward, the outlet opening of a change-over valve chest 18 of a change over valve 4 is opened. Working oil inside the change-over valve chest 18, at this time, flows into a servo piston chamber 16. Fuel oil inside a fuel in a fuel inlet passage 15, at the same time, flows into the change-over valve chest 18. Since the bore of a change-over valve chest inflow opening 36 is smaller than that of a change-over valve chest outflow opening 37, a pressure of the fuel inside the change-over valve chest 18 will not balanced with a pressure of the fuel inside the fuel inlet passage 15 so that the change-over valve 4 is moved up because of the differential pressure. The fuel inside the fuel inlet passage 15 flows into the servo piston chamber 16, hence forcing a servo piston 2 down together with a plunger 3.

Then the frequency search 13 is conducted and the registration frequency is confirmed (14) by the frequency selection circuit 4.  As a result, when a frequency fixing instruction 16 is disabled, a frequency search disable report 17 is given to a search frequency counter 5, and when the number of counts is a specified value or over by a timing circuit 6, the searching is made standby till a frequency re-search start instruction 19 is received. Thus, a useless frequency search time is reduced.

Filed: 1989-05-25
Abstract: PURPOSE:To use a common receiver in a single frequency and to simplify the circuit constitution of a receiver by differentiating the transmission period of a data request signal of each relay station and a mobile station data of a mobile station respectively. CONSTITUTION:A data request signal with its own relay station identification code added thereto is sent to mobile radio stations 15a-15c for different periods from relay stations 10-12 while the plural relay stations 10-12 are synchronized.
