Title: Recording or reproducing device
Inventor: WATANABE HIROSHI
IPC: G11B17/04
Filed: 1984-04-14
Abstract: PURPOSE:To prevent a device from invasion of a foreign material in the device in error by providing a slide cover inhibiting the movement of a closing cover when the closing cover closing an opening is closed when no cassette is loaded. CONSTITUTION:The interval between detecting members 3, 3' is set narrower than the width of a cassette 1 when no cassette is loaded. Since a turning cover 5 is locked with a slide cover 6 pressed into contact with the rear side of the cover 5, the cover 5 is not opened by a foreign material narrower than the width of the cassette 1 even if the cover 5 is pushed. When a motor is started attended with the loading of the cassette 1, a guide shaft 9 is pressed into contact with an end 18e of a moving lever 18 and the moving lever 18 is turned toward the arrow F. Thus, the slide cover 6 is elevated against the energizing of the springs 15, 16, moved in the direction closing the opening OP so as to prevent the invasion of a foreign material externally.

Title: Data processor
Inventor: KATO AKIRA
IPC: H04Q3/545
Filed: 1992-02-26
Abstract: PURPOSE:To prevent processing speed from being lowered by queuing. CONSTITUTION:In case of storing programs and data in a memory, a processor 3 turns a transfer circuit 11b to an allowable state by an access inhibiting line 200 and simultaneously writes the same program and data into memories 1 and 2. When all the required programs and data are written, the transmission/ reception circuit 11b is turned to an inhibited state by the access inhibiting line 200, and access from a bus 100 to the memory 2 is inhibited. When a system is turned to an operating state, the processor 3 reads an instruction required for running a program from the memory 2 through an instruction control circuit 33 and in the case of making access to the memory contents as data, the memory 1 is made access through a data access control circuit 32 and the bus 100. An input/output device 4 transfers data through a transfer circuit 11d, bus 100 and transfer circuit 11a to the memory 1.

Abstract: PURPOSE: To reduce the number of parts of a slat plate type compressor by fitting  in slidable condition a slant plate and a ball fitted swingingly in a piston by and simplifying the coupling structure of a piston and a slant plate and improve the operational efficiency of assembling and workability.  
     CONSTITUTION: A spherical receiving face 5 opening toward the center axis of a cylinder block 1 is formed in the center portion of a piston 4. A fitting groove 9 is cut in a ball 8 fitted swingingly in the receiving face 5, and a slant plate 7 and the piston 4 are engaged by inserting, in slidable condition and in the direction of turning, the peripheral edge of the slant plate 7 in the fitting groove 9.

Accordingly, the operational efficiency of assembling the both and the workability of parts can be improved, and the accuracy of assembling can  be increased, and, in its turn, the cost of production can be reduced.

Filed: 1989-03-28
Abstract: PURPOSE:To always obtain an accurate exposure value by measuring the chromaticity of an object, estimating the reflectance of the object by fuzzy inference and correcting and operating the exposure value based on the estimated reflectance. CONSTITUTION:Light from the object and light from an illuminating light source are respectively made incident on filters F1-F6, photoelectrically converted E1-E6 and sample-held H1-H6 to successively turn on selection switches S1-S3 and S4-S6. Then, they are successively A/D converted 1 and inputted in an arithmetic control part 3. The arithmetic control part 3 calculates the chromaticity, brightness and the exposure value corresponding to reference reflectance based on the brightness of the object and calculates the chromaticity of the illuminating light source. Then, it performs the fuzzy inference 4 based on the chromaticity value of the object and the illuminating light source and membership function stored in a memory 2 and outputs a correction value for the reference reflectance corresponding to the reflectance estimated from the chromaticity value. The accurate exposure value is calculated by correcting and operating the exposure value and displayed on a display part 5 so as to perform automatic exposure by an exposure control part 6.

Title: Pneumatic brake system for automobile
Inventor: KOJIMA HIROSHI
IPC: B60T15/36
Filed: 1980-06-06
Abstract: PURPOSE: To prevent a normal brake from being affected by air leakage, by using a valve, which acts in response to the pressure difference between a right and a left brake lines, to immediately stop supplying compressed air to the air-leaking line when air starts leaking from one of the brake lines.  
     CONSTITUTION: When a brake valve 12 is operated, compressed air in an air tank 11 is supplied to brake chambers 17W20 through valves to apply pressure to these chambers. If there is no air leaking from each brake line, no pressure difference is made between the ports 43, 45 of air leak prevention valves 15, 16 so that shuttles 47 are maintained in neutral position and the port 43, 45 are open. If air leaks from one of a right and a left front brake lines, for example, a pressure difference is made between the ports 43, 45 of the valve 15 so that the shuttle 47 comes into tight contact with the pressure-reduced port and closes it. For that reason, the compressed air is not supplied to the air leakage line.
