Title: Protective device for ac/dc converting apparatus
Inventor: YOSHINORI NAOTO
IPC: H02P7/292
Filed: 1988-05-13
Abstract: PURPOSE:To prevent an element from damaging by extinguishing a thyristor in a switch circuit to disconnect an AC/DC converter from a DC capacitor when arms are short-circuited in the converter. CONSTITUTION:An AC/DC converting apparatus is composed of a switch 3, a transformer 4, AC/DC converters (PWM converters) 5-6 connected in parallel, a DC capacitor 7, etc., and has an arm short-circuit detection circuit 9, an arm short-circuit protective circuit 10, and a controlling circuit 11. Switch circuits 12, 13 are connected between the converters 5-6 and the capacitor 7, and composed of diodes 14-15, and thyristors 16-17 connected at their cathodes in anti-parallel with the AC/DC converters. Thus, when an arm short- circuit accident occurs so that the detection circuit 9 detects it, the circuit 10 outputs an arc-extinction command to the thyristors 16-17, outputs an arc- ignition command to both the converters 5-6, and outputs a switch 3 open command.

Abstract: PURPOSE: To easily select desired pilot pressure and improve work efficiency in the above described device used for a snow removing machine or the like, by arranging relief valve, throttle valve and flow regulating valve in parallel connection in the downstream of a pilot pump driven with an engine.  
     CONSTITUTION: A pilot pump 7 is connected to a power transmission mechanism 2 of an engine 1, and a relief valve 8, throttle valve 9 and flow regulating valve 10 are arranged in parallel connection to a pipe line 11 connecting the pilot pump 7 to a tank 12, then liquid pressure at the upstream side of these valves is guided to an input torque controlling mechanism part 19. In this way, since an increase rate of liquid pressure guided to the input torque controlling mechanism part 19 for speed of the engine is lower in a region of larger work line load while higher in a region of smaller work line load, running line horse power can be fully increased in the region of smaller work line load, permitting the increase of work amount in the work line and the improvement of work efficiency.

Filed: 1994-05-30
Abstract: PURPOSE:To provide a liquid crystal display device which realizes a high-quality image display by dissolving the problem that display irregularity(crosstalk) occurs on an image screen by a simple and inexpensive means. CONSTITUTION:Using the voltage detected by a first detection electrode 13a as a reference voltage, the difference between this reference voltage and the voltage detected by a second detection electrode 13b arranged on the open end side of signal electrodes 2 is calculated by an operational amplifier circuit 11 and, at the same time, it is negatively fed back to each signal electrode 2 via a signal driver circuit 9. Since this difference voltage has a voltage waveform similar to that of the mean of the waveform-distorted voltage components on the signal electrodes 2, this difference voltage is amplified by the operational amplifier circuit 11 in such a direction and at an amplification factor as to dissolve the distorted voltage component which tends to be generated on the signal electrode 2 and negatively fed back to each signal electrode 2.

IPC: D01H1/34
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To make a tail yarn winding smoothly fly about from a tail yarn winding part provided in a lower part of a spindle after restarting a frame. SOLUTION: A ring rail 9 is suddenly lowered after completing the top bunch winding to form an oblique winding on the surface of a full bobbin B. When the ring rail 9 reaches a position L0 for starting the tail yarn winding, the moving direction thereof is reversed upward and the ring rail 9 is lifted to a lifting and lowering position L1 at a prescribed speed. When reaching the lifting and lowering position L1, the ring rail 9 is lifted to a primary lifting position and then stopped. Thereby, a tail yarn winding Y is helically formed in a tail yarn winding part 41. At the time of doffing, the tail yarn Y1 connected to the full bobbin B is cut with a cutting blade 42b when withdrawing the full bobbin B.  After restarting a frame, a tail yarn Y2 connected from the tail yarn winding to the bobbin is cut with a device for treating the residual yarn and the tail yarn winding Y flies about as a fiber from cut ends of the tail yarns Y1 and Y2.

IPC: G01M1/22
Filed: 1984-06-06
Abstract: PURPOSE:To eliminate an error by correction at each pitch for an efficient correcting operation, by positioning the extreme end of corrected positions corresponding to the predetermined pitch in the specified position in conjunction with the number of corrected positions depending upon a size of unbalance. CONSTITUTION:In case when an amount of shift by a phase shifting circuit 7 is zero, a phase differences relative to the reference phase signals of square wave signals I, II become 0 deg., 90 deg. respectively. A 2-element composite circuit 1 issues a signal A by DC signals (x), (y) and I, II. An amplitude of the signal A is proportional to a magnitude of unbalance of a specimen and further, a phase difference relative to the reference phase signal of the signal A has a definite relationship with an angular position in which an unblance of the specimem exists. A content of a memory circuit 4 storing a signal after rectification of the signal A turns out to be a detecting value of the magnitude of the unbalance of the specimen and further, by positioning the specimen in a position where the difference becomes 0 by comparison of output signals of phases of the signal A and a resolver (c), an unbalanced angular position of the specimen can be positioned in the definite position.

Filed: 1984-06-07
Abstract: PURPOSE:To prevent effectively deterioration of characteristic, short service life and instable quality of a surface acoustic wave device by applying hermetic while a stem and a shell are subject to heating and thermal insulation. CONSTITUTION:The baked stem 4 is heated by heaters 16, 18 provided respectively to a magazine 7 and a stem tape feeder 16 and the temperature decrease is prevented. The stem 4 subject to heating and thermal insulation in this way is applied to a lower electrode 11 for welding. On the other hand, after the shell 5 is heated and the heating is maintained by heaters 20, 21 provided respectively to a part feeder 12 and a shoot 13 respectively, the result is fed to the lower electrode 11. Then the stem 4 and the shell 5 fed to the lower electrode 11 are subject to seal welding while thermal insulation is applied by a high temperature nitrogen gas in the hood 22. Since the seal welding is applied in this state, no water content remains in the surface acoustic wave device.
