Title: Synthetic aperture sonar system
Inventor: YAMAGUCHI ISAO
IPC: G01S15/89
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a synthetic aperture sonar system which reduces range curvature correction errors, prevents a wave transmitter-receiver from being large in size and eases limitations to a multi-transmission count due to the speed of a hull. SOLUTION: A divided aperture propagation time-calculating part 32 is set at a range curvature-correcting part 30. The calculating part 32 calculates a signal reciprocation propagation time with the use of positions of a transmitting divided aperture part and a receiving divided aperture part, and obtains a range curvature correction time. A wave-transmitting receiving part 10 is provided with a PRF adjuster 14 and a divided aperture switch 16. The PRF adjuster 14 adjusts a PRF so that a ratio of an aperture length of a transmitter receiver and a divided aperture length becomes an integer. The divided aperture switch 16 switches a holding output of an acoustic conversion element of each divided aperture, calculates a sum of the outputs and transmits to a distance- compressing part 20.

Title: Valve driving device
Inventor: TSUJI TOSHIO
IPC: F01D17/10
Filed: 1987-11-24
Abstract: PURPOSE:To simplify the construction of a valve driving device by controlling supplying/discharging of a pressure oil to a hydraulic cylinder by means of a solenoid valve, thereby controlling both opening/closing operation of the valve and emergency opening/closing operation, by means of the hydraulic valve thus no more requiring a plurality of solenoid valves exclusively used for each operation. CONSTITUTION:Pressure oil from an oil pressure generator 11 is supplied sequently to an emergency trip unit 12, a solenoid valve 14 and a hydraulic cylinder 10, so as to drive a main steam stop valve 1. When the solenoid valve 14 is opened, the pressure oil is supplied from the emergency trip unit 12 to inlets 10b, 10d of the hydraulic cylinder 10. Then a disc dump valve 15 is pressurized to raise a piston 10c with exhaust oil passage 10a closed, and thereby the valve port 1c of the main steam stop valve 1 is released. On the other hand, when the electromagnetic valve 14 is closed, the pressure oil in the lower part of the piston 10c is discharged to a discharge oil receiving part 18 through an oriffice 16 and the solenoid valve 14, and then a valve body 1a is lowered so that the valve port 1c is closed.

Title: Vacuum cleaner
Inventor: ISHIHARA HIROYASU
IPC: A47L9/00
Filed: 1990-10-30
Abstract: PURPOSE:To prevent a temperature sensing switch from being heated and an electric blower from being unexpectedly stopped by providing a partition wall plate for opening an exhaust circuit when a shutter is closed and closing the exhaust circuit when the shutter is opened integrally with the shutter and providing the temperature sensing switch nearer to a suction port side than to the partition wall plate of the exhaust circuit. CONSTITUTION:During circulation of exhaust air, a hose is removed from a suction port 5. A shutter 9 is closed so that a partition wall plate 10 opens an exhaust circuit 11. Exhaust hot air from an electric blower 7 enters a dust collection chamber 6 through the exhaust circuit 11. Microorganism sucked in to the dust collection chamber 6 is killed by the hot air. At this time, when a temperature sensing switch 12 provided in the exhaust passage of the circuit 11 is heated and its temperature reaches a prescribed setting temperature, for example, the killing temperature of the microorganism, the switch 12 operates to stop the driving of the electric blower 7. Therefore, after the microorganism is killed, the electric blower is prevented from being driven.

Title: Encoder interpolation device
Inventor: YUGAWA HIROSHI
IPC: G01D5/36
Filed: 1991-11-11
Abstract: PURPOSE:To generate sensing signals of high accuracy by controlling the counting operation of two up/down counters, allowing assumed Lissajous signals to follow up after two real Lissajous signals having 90 deg. differing phases, reading interpolation data from a memory means using the assumed Lissajous signals as address, and interpolating the output of encoder. CONSTITUTION:Two Lissajous signals having 90 deg. differing phases emitted from an encoder are converted into digital signals by A/D convertoors 1, 2 and supplied to comparators 3, 4 as real Lissajous signal. The outputs of up/ down counters 5, 8 are fed as assumed Lissajous signal to one of the comparators 3, 4, and the two are compared. AND gates 6, 9 supply signals to other AND gates 7, 10 depending upon the result from comparison, and thereby the operation of the counters is controlled, and the assumed Lissajous signals are left following up after the real Lissajous signals. These assumed Lissajous signals are fed to a ROM 11 as address signals, and corresponding data is obtained. This, way permits interpolation of the encoder output accurately at all times, which leads to precise sensing of the displacement and velicity of the object.

IPC: G03G21/10
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To hold an excellent cleaning performance even under a low temperature environment by disposing a cleaning blade and a pressing member or a coupling member almost in parallel. SOLUTION: This device is provided with the cleaning blade 3 fitted to a discharge toner recovery container 5 by a blade holder 7 and the plate-like pressing member 4 made to adhere to the whole part or one part of an abutting part(on the container 5 side) between the container 5 and a photoreceptor case 2 by an adhesive layer 31 such as hotmelt. Then, the pressing member 4 is made of an identical material to the blade 3 and disposed almost in parallel with the blade 3. Thus, when abutting pressure with respect to the surface of the photoreceptor becomes weak because the blade 3 contracts, the pressing member 4 also contracts and the thickness thereof is reduced. Then, since the blade 3 approaches the photoreceptor 1 by as much as the reduction of the thickness, the abutting pressure is held to be almost constant.
