Title: Detection of abnormality in continuous casting
Inventor: SHIRAISHI YUKITAKA
IPC: B22D11/20
Filed: 1984-06-05
Abstract: PURPOSE:To decrease defective billets and to prevent equipment trouble by detecting the generation of abnormality from the difference between the total theoretical drawing force from a mold for continuous casting upto pinch rolls and the total actual drawing force determined from the total electric power for driving pinch rolls and the drawing speed. CONSTITUTION:The total theoretical drawing force SIGMAFw is calculated from the deformation resistance, frictional resistance, etc. corresponding to the respective sectional sizes, speeds and temps. in the course of the mold 3, grid 4, roller apron 5 and pinch roll group 6 of a continuous casting machine and is inputted to a setter 12. On the other hand, the total actual drawing force SIGMAFn determined from the feed volage and current to motors 6M for driving the pinch rolls 6 and the drawing speed 14 of the billet is put into an arithmetic unit 11 which compares said force with the force SIGMAFw and executes immediately an inspection and countermeasure by judging that some abnormality arises if the difference therebetween exceeds a set permissible value alpha. The abnormality is known even in the stage of stable drawing or size changing and the generation of the defective bilets is decreased by the countermeasure. The equipment trouble is thus prevented.

Title: Torque transmission
Inventor: KASHIMA MITSUHIRO
IPC: F16D43/284
Filed: 1990-05-02
Abstract: PURPOSE:To transmit large torque in a small-sized torque transmission by providing a pump driven by relative rotation between a rotary shaft and a case, and a piston capable of exerting a compressing force according to a discharge pressure of the pump to a rotor and a stator. CONSTITUTION:Upon rotation of a rotary shaft 1, rotational torque is transmitted from the rotary shaft 1 to a case 2 by a frictional force generated between a rotor 5 and a stator 6. If a load applied on the case 2 is large, slide is generated between the rotor 5 and the stator 6, thus causing relative rotation. Accordingly, an inner rotor 13 and an outer rotor 14 are relatively rotated, and this relative rotation drives a trochoid pump 12, thus expanding or compressing an operating chamber. In the case of expansion of the operating chamber, operating oil staying in an oil chamber 22 is sucked through a check valve 19 while in the case of compression of the operating chamber, the operating oil is discharged to another oil chamber 27 via another check valve 20. Therefore, an increase in pressure of the oil chamber 27 increases, a compressing force of a piston 10 exerted on the rotor 5 and the stator 6 so that the frictional force between the rotor 5 and the stator 6 is increased, thereby enlarging transmission torque.

Title: Cloth holding device of sewing machine
Inventor: SAKAKIBARA YASUO
IPC: D05B29/12
Filed: 1990-05-02
Abstract: PURPOSE:To prevent the presser foot supporting body from turning at the time of sewing, and also, to simply execute the change of a presser foot by small force by providing an energizing member for suppressing the turning of the presser foot supporting body, when the presser foot is provided in a cloth holding position by turning of the presser foot supporting body, and an energizing force suppressing member for suppressing the energizing force of the energizing member, when a holding rod is in an ascent position. CONSTITUTION:When a presser foot is provided in a cloth holder 3 position by turning of a presser foot supporting body 12, an energizing member suppresses turning of the presser foot supporting body. Also, when a holding rod 4 is in an ascent position, an energizing force suppressing member suppresses energizing force of the energizing member. Therefore, when the holding rod 4 is in a descent position, that is, when a sewing work is executed, turning of the presser foot supporting body 12 is suppressed by the energizing force of the energizing member, cloth can be held down satisfactorily by a presser foot 8, and on the other hand, when the holding rod 4 is in an ascent position, the presser foot supporting body 12 can be turned by small force. In such a way, when the holding rod is in an ascent position, it is unnecessary to hold cloth by the holding foot, therefore, in such a state, by suppressing the energizing force of the energizing member, the presser foot can be changed simply.

Title: Transmitter for digital signal
Inventor: SEKI TOSHIMICHI
IPC: H04J4/00
Filed: 1981-07-23
Abstract: PURPOSE:To improve substantial signal transmission speed, by using a frequency shift modulation wave with different channel number, and transmitting one digital signal on the same transmission path at the same time. CONSTITUTION:An output of frequency shift modulators 110 and 111 is both transmitted with a transmission line 31, a frequency shift demodulator 240 receives frequencies f0 and f1 for demodulation, and a frequency shift demodulator 241 receives frequencies f0 and f1 for demodulation. A serial parallel converter 250 modulates an output of the demdoulator 240 into a parallel signal and a serial parallel converter 251 converts the output of the demodulator 241 into a parallel signal. Thus, the output of the converter 250, the output of the converters 120 and 251 and the code of the converter 121 are respectively equal. When the output of the converters 250 and 251 are arranged overlappingly, the code is the same as that of an A/D converter 13 and the code is converted into a D/A converter 26. Thus, since the transmission line is operated in parallel, the  amount of information transmitted for a specified time can by doubled for a prescribed bit.

Title: Playback servo device
Inventor: OKITA MASAYA
IPC: G11B19/28
Filed: 1985-05-29
Abstract: PURPOSE:To prevent a playback image from being distorted by detecting the interval of a playback horizontal synchronizing signal and computing and storing a speed distribution state including an irregularity in rotation during recording, and performing open loop control over a motor driving system on the basis of the stored speed distribution state. CONSTITUTION:The AC component of the output of a D/A converter 19 is passed through a power amplifier 23 to apply a control voltage of the same frequency to a disk driving motor 2. When the frequency of the applied voltage is low, the output of an F/V converter 21 is controlled to the same AC waveform with the output of the D/A converter 19 and as the frequency increases, the phase of the output voltage of the F/V converter 21 is delayed. The frequency, gain, and phase of the irregularity in rotation during recording are calculated from the value obtained by counting the interval of the playback horizontal synchronizing signal HD with specific reference clock pulses and they are divided by the transfer function of a motor control means and stored in a motor control means as control references to obtain the same irregularity in rotation with the recording. Consequently, speed control which reproduces the same irregularity in rotation with the recording is performed and an image is prevented from being distorted during reproduction owing to the irregularity in rotation during the recording.

Title: Transmission delay time automatic correction method, center equipment using this method and communication terminal equipment
Inventor: MOGI UMIHIKO
IPC: H04N7/10
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To properly correct a transmission signal timing for each channel in response to an actual transmission delay time without giving an effect on usual communication by using a different channel from a communication channel and its control channel to periodically correct a transmission delay time of a communication terminal equipment. SOLUTION: A mixing/distribution section 7c of a center equipment 10 provides an output of a high frequency signal received from a terminal equipment to an incoming transmission line interface section 5c for each high frequency channel. The incoming transmission channel interface section 5c demodulates the high frequency signal into a digital signal and measures its delay time and informs a difference from an optimum value to a central control section 1c.  The central control section 1c reports a timing correction value of a transmission signal to be set by a terminal equipment A at a succeeding transmission to an outgoing transmission channel interface section 4c based on the difference and uses a transmission delay time correction exclusive channel different from data and its control channels to send the correction value superimposed on a transmission signal to the terminal equipment A via the mixing/ distribution section 7c.
