Filed: 1993-06-23
Abstract: PURPOSE:To prevent the severe wear and heating of seal rings by bringing a static seal ring into sliding contact with a rotary seal ring only when a rotating member requiring the supply of fluid is stopping, and insuring the sealing property between the both. CONSTITUTION:A fluid is guided to a pressurizing chamber 9 through the fluid inlet port 4e of a retainer 4 in the state where the rotation of a rotating shaft 1 is stopped, a static seal ring 3 is pushed onto a rotary seal ring 2 by the fluid pressure to seal the space between seal end surfaces 2a, 3a. O-rings 7, 8 are twisted as being rolled according to the seal ring 3, the seal ring 3 is energized by its reaction in the direction of separating from the seal ring 2 against the pressure of the fluid guided to the pressurizing chamber 9, and the fluid in the pressurizing chamber 9 is supplied to the fluid passage 1b of the rotating shaft 1 through a communicating passage 10. The fluid to the pressurizing chamber 9 is stopped according to the rotation of the rotating shaft 1, whereby the sealed ring 3 is separated from the seal ring 2 by the reaction accompanying the twisting of the O-rings 7, 8 to release the sealed state. Thus, the severe wear and heating of the seal end surfaces 2a, 3a can be prevented.

Title: Image forming device
Inventor: YANO KOJI
IPC: G03G21/14
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To make timing when the temperature of a fixing device rises to a fixable temperature almost the same as timing when a polygon motor reaches a normal rotation state by starting the driving of the polygon motor after performing detection by a temperature detection means of the fixing device. SOLUTION: It takes time t1 until the temperature of a fixing device rises to a fixable temperature after starting energizing an AC heater in a heating roller and it takes t2 until a polygon motor reaches the normal rotation state where its rotation becomes stable after starting rotating the polygon motor. The driving of the polygon motor is started by energizing the polygon motor when the fixing device reaches such a temperature (K1 deg.C) that the time required for the fixing device to reach the fixable temperature becomes t2 by energizing the fixing device so that the temperature of the fixing device is made to rise in order to make the timing when the temperature of the fixing device rises to the fixable temperature the same as the timing when the polygon motor reaches the normal rotation state.

IPC: E02D9/00
Filed: 1984-07-23
Abstract: PURPOSE:To automate the measurement of a position, by moving three or more of receiving coils for detecting magnetic fields to allow the interlinkage surfaces of the receiving coils to be parallel to the longitudinal direction of a tunnel and allowing the positions of transmitting and receiving coils to coincide to measure the induced voltage of each receiving coil. CONSTITUTION:Receiving coils 4-1-4-7 are suspended from coil support shafts 8-1-8-7 arranged to receiver 5 horizontally in parallel relation to each other at equal intervals and the interlinkage surfaces of said coils are allowed to be parallelly spaced apart to each other in a vertical state at equal intervals. Each receiving coil group is rapidly moved to the vicinity of the position directly above a transmission coil by using a measuring vehicle 7 and induced voltage measuring machinery such as a selective amplifier is placed on the measuring vehicle 7 to perform measurement on the site. By this method, because the change-over of the receiving coils for measuring induced voltage can be controlled by a microcomputer and the induced voltage measuring machinery can be connected by an on-line system, the positional measurement can be performed automatically and safely at a high speed in a wide range.

Title: Speed ratio controller for continuously variable transmission for vehicle
Inventor: OSANAI AKINORI
IPC: F16H61/662
Filed: 1983-08-22
Abstract: PURPOSE:To obtain highly economical fuel consumption during acceleration by suppressing change of the gear ratio of a continuously variable transmission till attainment of the target value of engine speed after the actual engine speed has exceeded the gear ratio suppression judgement reference value. CONSTITUTION:This gear ratio suppression device is equipped with a gear ratio change suppression judgement speed decisional means and a gear ratio changing speed suppression means. After the actual engine speed has exceeded the gear ratio suppression judgement reference value determined by a gear ratio suppression judgement speed decisional means, the said gear ratio changing speed suppression means shall suppress the change of gear ratio in the continuously variable transmission until the target value of the engine speed is attained. Thereby the stepless speed changer transmits the engine power at a constant gear ratio during acceleration of the car. Accordingly drop of the transmission efficiency otherwise likely to originate from change of gear ratio of the said transmission can be prevented, and a high economical performance is obtained even under output acceleration.

Title: Count pulse generation circuit
Inventor: ADACHI SATOSHI
IPC: H03K21/02
Filed: 1987-06-19
Abstract: PURPOSE:To prevent a pulse recognized erroneously from being generated and a count pulse from being missed, by providing a direction discrimination circuit, a reservation circuit, a count direction storage circuit, and a pulse synthesis circuit, reserving the number of superposition of an edge change signal when it occurs in a prescribed period, and outputting the signal as a count pulse at an appropriate time corresponding to the leading direction of a phase. CONSTITUTION:In a case where the phase difference phi of input signals phiA and phiB that are square waves and a duty factor of 50%, etc., are set at normal ranges and an operation in a forward direction is performed, the edge change signal UEN synchronized with a clock pulse CK is outputted from the direction discrimination circuit 10. Therefore, for example, a count pulse generation circuit 100 in the periods hi and ij of the clock pulse detects the generation of the superposition of the signals phiA and phiB in the period hi. And the circuit outputs one normal up count pulse U1 by judging from a count direction just before stored in the count direction storage circuit 50, and also, accumulates a spare count pulse as a reserve signal. Since it is not required to handle a pulse as the abnormal one as the pulse counted erroneously or to issue alarm even when change in a superposed edge occurs, it is possible to attain a fast operation.

In addition, the nonconductive and nonmagnetic part 20 is formed by the sputtering method to protect the surface of the device 21. In such constitution, the piece 13a is on the substrate to eliminate the adhesion between the piece 13a and the device 21. Thus the deterioration of sensitivity caused by the shift of position and the liberation can be prevented.

Abstract: PURPOSE:To dispense with the starting circuit of a rotary electric machine for a turbocharger and the like by providing a control means which drives the rotary electric machine and operates a compressor when an output signal is obtained from a rotational decrease detection means. CONSTITUTION:ON/OFF operation of a manual switch 9 is checked, and in the case when it is set ON, a turbine rotational speed Nt is measured by a frequency signal from the fixed coil of a rotary electric machine 3. Then, the measured turbine rotational speed Nt is compared with a specified rotational speed N* (the turbine rotational speed for which electric motor drive is required since a turbine is stopped because of its low rotation). In the case when the rotational speed Nt equivalent to the specified rotational speed N* has not yet been achieved it is compared with a turbine rotational speed Nl which enables electric motor operation without using starting circuit. When the rotational speed Nt is larger than Nl, an electric converter 41 is commanded to electrically drive the rotary electric machine 3, and energize a compressor 22 so as to increase supercharger pressure.
