Title: Twist agitator
Inventor: YOSHIDA TAKUMI
IPC: G01M17/007
Filed: 1993-03-03
Abstract: PURPOSE:To provide a twist agitator which can make a desired agitation even when an agitation command has a low frequency. CONSTITUTION:A speed variation generated by torque ripple command value DELTAtaur* is operated as speed ripple R and added to a deviation detection point 6, so that torque signal tauN* outputted by a speed amplifier 7 is a signal resulting from cancelling a speed variation generated by torque ripple command value DELTAtaur*. Therefore, even when the frequency of the torque ripple command value DELTAtaur* is low, a torque ripple is not cancelled by a speed control loop.

Abstract: PROBLEM TO BE SOLVED: To prevent the positional deviation between respective parts caused by a change in temp. by attaching a forward and backward rotating fan member for introducing air into an image forming chamber or a thermal fixing chamber, to a casing or a partition plate. SOLUTION: The inside of the casing 1 is partitioned into the image forming chamber A and the thermal fixing chamber B by the partition plate 10 and the forward and backward rotating fan member 11 for introducing the air into the image forming chamber A or the thermal fixing chamber B is attached to the partition plate 10. When the temp. in the image forming chamber A is higher than a first reference temp., the fan member 11 is rotated forward, to introduce the air in the image forming chamber A into the thermal fixing chamber B. On the other hand, when the temp. in the image forming chamber A is lower than a second reference temp., the fan member 11 is rotated backward to introduce the air in the thermal fixing chamber B into the image forming chamber A.  Thus, the inside of the image forming chamber A is always kept at the temp. suitable for forming an image and the electric characteristics, etc., of each part, housed in the chamber A can be kept almost constant.

Title: Digital radio communication equipment
Inventor: INOUE SEIYA
IPC: H04B1/38
Filed: 1993-02-09
Abstract: PURPOSE:To suppress production of an error of reception data when an antenna is selected by applying differential coding to data to be sent. CONSTITUTION:Coded data outputted from a differential coder 21 have the same bits of one preceding data bits when information data are zero and coded by inverting one preceding data bits when information data are logical 1 and the coded data are subject to PSK modulation by a PSK modulator 2. Since the information data are sent as a change of the phase of a carrier by using the differential coder 21 and the PSK modulator 2 at a sender side, and when the data are received, a delay detection demodulator 22 is used to detect a change in the phase of a carrier of one preceding bit and a carrier of a current bit thereby demodulating the information data. As a result, even when an antenna is switched and a phase of a PSK modulation wave received by the delay detection demodulator 22 is jumped, no long burst error is caused differently from the use of a synchronization detection demodulator and only a 2-bit error at maximum is caused.

CONSTITUTION:At normal operation, a toggle switch 10 is in constant current control circuit position 7, and according to current reference 51, the current flowing in an electromagnet 5 is controlled by a closed loop control system. When the constant of electromagnet 5 is changed due to replacement, switching, etc., the toggle switch 10 is, by switching signal 54, switched to ignition phase signal position 53. With the phase determined by the ignition phase signal 53, a phase control circuit 8 operates a control rectifier 3. The electromagnet 5 is applied with a constant voltage. A calculation device 11, from DC voltage signal 55 and DC current signal 52, at the time when the electromagnet is applied with current in open loop, calculates resistance of the electromagnet and time constant determined based on inductance and resistance, so as to decide proportional gain and integration time of the constant current control circuit. With this, even if inductance and resistance of the electromagnet change, stable and effective control is available.

Abstract: PURPOSE: To supplement the reference signal having been missed by external noise in a weak electric field and prevent synchronization disturbance by charging  and discharging an integrating circuit at the output timings of a monostable multi  which generates the reference signal of cylinder control system.  
     CONSTITUTION: The vertical synchronizing signal A separated from the video signal triggers a monostable multi 19, by the rise of the output signal B whereof an integrating circuit 35 is charged and by the fall of the output B it is discharged. The output of the circuit 35 is applied to a differential amplifier circuit 36 and when it is below the reference voltage of a reference bias circuit 37, the output of the circuit 36 is not obtainable. On the other hand, when the period signal A is omitted by the timing-t of the signal D owing to noise, etc., the output of the circuit 35 reaches a reference voltage VTH and a pulse F is outputted from the circuit 36. This output is then applied to the input side of the monostable multi 19 and the monostable multi 19 is trigged by the frequency close to normal operation. Hence, the occurrence of disturbance in the control system is obviated within the evacuation range of the control system.
