Patent JP-S60263733-A (JP)
Title: Electromagnetic powder type clutch
Inventor: GOSHIMA TAKAHIRO
IPC: F16D37/02
Filed: 1984-06-12
Abstract: PURPOSE:To improve reproductivity of transfer torque, by a method wherein a magnetic flux generating means, which generates magnetic flux only in the central part of a motion gap and in a position in the vicinity thereof, is located independently from an electromagnet. CONSTITUTION:Electricity is charged through slip rings 21a and 21b from a brush 22 to an exciting coil 3, which causes a motion gap 37 to emanate magnetic flux. The flow of a current through the coil 3 results in formation of a magnetic circuit passing through yokes 1a and 1b, the motion gap 37, and a rotor 10 to generate magnetic flux. Thus, the presence of an exciting current to the coil 3 determines whether rotary torque may be transmitted or not. Thus, even when the charge of electricity through the coil 3 is disconnected by means of magnetic flux PHI8 of a permanent magnet 8, magnetic powder 4 is continued to be held at the central part of the motion gap 3 without scattering. This reduces movement of the magnetic powder 4 into the motion gap 37, decreases production of a change in a coupling condition of the magnetic powder during magnetization effected through the working of the coil 3, and improves reproductivity of transfer torque.

Title: Repair engineering method of pipe path
Inventor: WAKAGI YASUHIRO
IPC: B29C63/36
Filed: 1987-05-20
Abstract: PURPOSE:To repair a pipe path on the spot without digging up a road, by a method wherein along with insertion of a tubular liner within a pipe path, the liner is pressed against an inner circumferential surface of the pipe path with fluid pressure, a resin absorbent material of the liner is impregnated with resin while keeping this state as it is and then curable resin is cured. CONSTITUTION:A liquid poured into an inversion guide pipe 4 through a water pouring hose 2 extrudes a tubular liner 3 composed of a flexible resin absorbing agent with its static pressure while inverting the tubular liner 3, inserted into a time-worn pipe 1 and penetrated through the time-worn pipe 1 at last. Thermosetting resin agitated by an agitating material 7 within an agitating tank 8 is sent within a resin pouring hose 10 with pressure by a pump 9 and kept permeating into the liner 3 through a resin casting port 6. In this instance, the thermosetting resin pressurized by the pump 9 stays especially much on a damaged part of an inner wall surface of the time-worn pipe 1. therefore, an irregular surface is changed into a flat surface by repairing its irregular surface. A temperature of a fluid pressing the liner 3 against the inner wall surface of the time-worn pipe 1 is raised through circulation of the fluid heated by a boiler and the cure of the foregoing thermosetting resin progresses. With this construction, a rigid lining pipe is formed on the inner wall surface of the time-worn pipe 1 and repairing is completed.

IPC: F04C15/00
Filed: 1994-06-02
Abstract: PURPOSE: To ensure temporary disconnection of a steering assisting pump by providing the steering assisting pump with a hydraulic clutch which can be operated via the lubricating oil circulation system of a drive. CONSTITUTION: A steering assisting pump 20 having a hydraulic clutch 18 is connected via a branch pipe 16 to a lubricating oil circulation system 14 extending from a lubricating oil pump 12 driven by an internal combustion engine 10, and is similarly driven by the internal combustion engine 10 via a belt pulley 22. When the internal combustion engine 10 is in a high rotation range and wheel power is small, low manual torque is generated on a steering wheel 32. The manual torque is detected by a torque sensor 34 and transmitted to a control circuit 26, and when the manual torque is not greater than a predetermined value, a solenoid valve 26 is switched to connect the branch pipe 16 to the clutch 18. Thus, pressure from the lubricating oil pump 12 disconnects the clutch 18 to disconnect the steering assisting pump 20 from the belt pulley 22.

Filed: 1988-05-18
Abstract: PURPOSE:To suppress ill influence of noise by judging whether the latest interrupt period is smaller than half the interrupt period on the occasion before the former one about the ignition signal fed as an interrupt signal. CONSTITUTION:An ignition signal given by a distributor 2 is fed into a sensor circuit 23 of an ECU 10 through a signaling line 1 and shaped into a rectangular wave at a specified voltage level. The CPU 30 clocks the interrupt timing, and thereform the latest interrupt period and the interrupt period on the occasion before the former one are computed. They are subjected to comparison to know if the latest interrupt period is smaller than half the interrupt period on the occasion before the former one, and if yes, it is judged that noise has generated interruption, and the value as the sum of the previous interrupt period and the latest interrupt period is corrected as the latest interrupt period. The interrupt period corrected in this manner becomes an ignition period getting rid of noise influence, and thereby precise number of engine revolutions and fuel injection signal can be emitted.

Abstract: PURPOSE: To make it possible to relieve or suppress a 'burn' by providing the device with a driving means including a means for setting the display state of pixels, a means for impressing DC voltage between electrodes and a means for changing over the polarities of the DC voltage. CONSTITUTION: The voltage exceeding the one threshold voltage of the chiral smectic liquid crystals is impressed on the pixels on the scanning electrodes selected by the first phase (1/2.ΔT period) of a scanning selection signal SS, by which the display state of the pixels is non-selectively erased.

The DC voltage VDC of ±1.5V0 is impressed as the scanning non-selection signal SN on the scanning electrodes not impressed with the signal SS.  The first and second periods may be set in on one perpendicular scanning period of one frame scanning period or one field scanning period and may be set in one horizontal scanning period and, therefore, the polarities of the DC voltage VDC are changed over in these periods.

Abstract: PURPOSE:To obtain good acoustic characteristics by installing opposite strings opposite strings for playing which are fixed to the surface diaphragm of the stringed instrument. CONSTITUTION:The stringed instrument 20 is provided with the strings 28 opposite the strings 25 for playing. The strings 28 generate tension 2A by a peg 23.

IPC: C04B38/06
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain pottery improved in strength and capable of using for various uses by including carbon fiber into porous pottery in which pores are dispersed. SOLUTION: This pottery is obtained by mixing clay with resin filler and carbon fiber and kneading, forming and drying the mixture and baking the mixture and applying glaze and baking the glaze. For example, drying can be carried out by natural drying or forced drying and ungrazing may be carried out for 6-8 hr at 550-800 deg.C and baking can be carried out for 13-18 hr at 1,150 to 1,300 deg.C. For example, a hollow resin filler is used as the resin filler. In the above step, the resin filler is removed by burning and pores are formed in the part of the resin filler. In the carbon fiber, the content ratio may be different according to place, though uniform disperse of carbon fiber is generally preferable. A carbon fiber woven into fabric can be used in addition to fibrous carbon fiber as the carbon fiber.  It is also preferable that disperse ratio of pores is low (or high) in the inside and high (or low) in the surrounding part.

Abstract: PURPOSE:To improve the performance of a cache memory device by previously deciding whether the entry of the succeeding address of a current address outputted from a CPU exists in a cache or not and detecting coincidence between the address concerned and an address used for the decision of the preceding program to decide a hit. CONSTITUTION:Using a surplus time obtained after deciding a hit or mishit by checking a TAG memory 201 in the cache, an entry deciding circuit previously decides whether the data of the succeeding address of the current address outputted from the CPU are entered in the cache or not. An address comparator 203 compares the address outputted from the CPU at the time of accessing the succeeding program with the address used when the entry deciding circuit 1 decides the entry by the preceding program to detect their coincidence or discrepancy. When the coincidence is detected by the address comparator 203, a hit is immediately decided. Consequently, data entered to the cache memory is read out without requiring a weight cycle.
