Title: Device for preventing vibration of wire electrode in wire cut electrical discharge machining
Inventor: INOUE KIYOSHI
IPC: B23H7/02
Filed: 1983-07-12
Abstract: PURPOSE:To make it possible to damp or cease vibration of a wire electrode which generates upon electrical discharge machining, by generating high-frequency oscillation for damping or ceasing the free-vibration of the wire electrode with the use of electrostrict materials or magnetostrict materials. CONSTITUTION:When a wire electrode 1 comes to a position indicated by the chain line due to generation of vibration, the capacitances or distances between detectors 14a vary, and therefore, these variations in capacitance are taken out by means of vibration detecting devices 14 to discriminate the frequency, amplitude and direction of the vibration of the electrode 1 with the use of vibration detectors 14b which delivers detection signals to vibration drive and control devices 10d for vibrators 10a. Each device 10d controls magnetic excitation to an electrostrict member 10a which is disposed in the same phase as that of each vibration detecting device 14 that detects displacing vibration from the center position of the electrode, so that there is generated oscillation having the inverse phase but the equal amplitude with respect to the detected free vibration of the electrode 1. The oscillation of the electrostrict member 10a is applied, as vibrating force having an inverse phase, to the electrode 1 through a ring 11 so that the electrode 1 is excited by being contacted with the ring 11, thereby the free vibration of the electrode 1 may be damped, ceased or extinguished.

Title: Fuzzy arithmetic circuit
Inventor: HASEGAWA KOHEI
IPC: G05B13/02
Filed: 1990-05-17
Abstract: PURPOSE:To obtain a new fuzzy arithmetic circuit with the high responsiveness by providing two operational amplifiers, a comparison signal, a control part, and a function generating circuit and actuating the operational amplifiers only in a linear area of the arithmetic circuit. CONSTITUTION:When an input signal V1 is inputted to the operational amplifiers OP1 and OP2 respectively, the outputs P1 and P4 of the amplifiers OP1 and OP2 cross the voltage of 0 level at the positions decided by the comparison voltage levels VR and VL respectively. Thus both outputs P1 and P4 rise or fall. These output characteristics are turned into the outputs P2 and P5 having the changed slopes by the regulators VR1 and VR2. The comparators DC1 and DC2 are set at a contact voltage level -VBE and then turned into the outputs P3 and P6 at the negative and positive sides centering on the cross positions decided by the comparison voltage levels VR and VL respectively. At a function generating part FG, the outputs P3, P6 and P7 are inputted to the bases of transistors 5 - 7 respectively and synthesized. Thus the trapezoidal output characteristic VOUT is obtained. Therefore a fuzzy arithmetic circuit using the amplifiers OP1 and OP2 can maintain high speed responsiveness.

Title: Governor rope bracing apparatus for elevator
Inventor: YAMAKI MASAMITSU
IPC: B66B7/06
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus which can restrain swinging of a moving body side governor rope effectively without generating malfunction in an emergency bracing apparatus. SOLUTION: A cushioning member 9 such as sponge is fitted between governor ropes 7a, 7b and a hoistway wall 8. If the governor rope 7 swings due to earthquake, strong wind or the like and amplitude is beyond a fixed value, the governor rope 7 collides with the cushioning member 9 and absorbs swing energy, so that swing of the governor rope 7 can be restrained. Even if a pull-up lever 6 comes into contact with the cushioning member 9, the cushioning member 9 is sufficiently soft, which will not generate any catch. It is thus possible to avoid malfunction in an emergency bracing apparatus.
