Title: Replacement method of arc sensor protecting window
Inventor: TORII NOBUTOSHI
IPC: B23K9/32
Filed: 1991-04-02
Abstract: PURPOSE:To adequately find the replacing time of a protecting window of an arc sensor by using a function originally provided for the arc sensor. CONSTITUTION:An unused (new) arc sensor protecting window 28 is mounted for an arc sensor unit 20. A reference reflecting plane 30 is provided at a predetermined position from the front face of the arc sensor protecting window 28. In this state, when a laser light 26 is scanned to the reference reflecting plane 30, a reflecting light 27 is detected. The detecting amount of the reflecting light is stored in a memory as the first detecting amount. Subsequently, after the arc sensor protecting window 28 is subjected to arc welding as it is, the reflecting light 27 from the reference reflecting plane 30 is detected in the same manner as when the arc sensor protecting window is not yet used. The detecting amount of light is set as the second detecting amount. Based on the first and second detecting amounts of light, the degree of dirtiness of the arc sensor protecting window 28 is evaluated, thereby to determine whether the arc sensor protecting window 28 should be replaced.

Abstract: PURPOSE: To enable the continuous operation of an inverter, by suppressing the output voltage of the inverter and raising its output frequency by a detection signal corresponding to the excess in the output voltage of the inverter beyond a prescribed level when an ozone generator is partly defective.  
     CONSTITUTION: When the fuse 52 of the ozone generator 5 melts off and the output voltage Vo of the inverter exceeds the detection level of an overvoltage detection circuit 30, a signal m is applied from the detection circuit 80 to a turn-on pulse generator 81. A signal e is supplied from the generator 81 to an oscillation circuit 77 and a pulse amplifier 78. At that time, the oscillation circuit 77 is reset to produce a signal d of constant period again and the turn-on pulse generator 81 decrease the current setpoint g of a voltage control circuit 71. The signal e is thus sequentially increased with the decrease in the input current Id to the inverter. Finally, the signal e reaches the inherent period of the oscillation circuit 77 and the output voltage Vo coincides with the prescribed level. Therefore, the inverter can be operated continuously.

A controller 5 receives an output shaft rotation angle signal s1 and an accelerator open degree signal s2, and delivers an open and close signal s3, in accordance with the afore-mentioned signals, to a solenoid 4b for controlling shut-off valve 4. The opening timing of the shut-off valve 4 is synchronized with an air-intake valve 11, for controlling the shut-off valve in such a way that the opening time period is short upon low load conditions but long upon high load conditions, thereby the volume of intake-air may be precisely controlled without the shut-off valve 4 being opened before the opening of the air-intake valve 11 and the pumping loss of the engine may be reduced.

IPC: H04L7/00
Filed: 1983-06-03
Abstract: PURPOSE:To prevent the generation of distortion by providing a control means controlling write/read of a write/read asynchronizing memory and a memory circuit correcting shortage of a receiving PCM signal so as to attain ease of decoding when the received PCM signal and a frame clock of a terminal station device are asynchronous. CONSTITUTION:A marker signal is inserted at each frame to the received PCM signal by data selecting circuits 1, 12 of a buffer circuit and the PCM signal inserted with the marker is written in or read out of an FIFO memory 2 by a clock from 9 write control circuit 3, and a read control circuit 4. Further, the phase of the marker signal read from the memory 2 and the frame phase from a read control circuit 19 are compared by a comparator circuit 16 so as to synchronize the PCM signal with the frame phase. A numeral train inserted to a time slot of the marker is generated from a counter 10 of the buffer circuit and applied to circuits 10, 16. Thus the phase synchronism between the PCM signal and the frame clock is taken easily by the read control circuit 19, FF 20, 21 and a memory circuit 23 or the like so as to decode the PCM signal with no distortion.

Title: Ink jet head
Inventor: ABE TOMOAKI
IPC: B41J2/055
Filed: 1989-04-19
Abstract: PURPOSE:To improve the response property of frequency and, to obtain sufficient discharge speed and sufficient discharge amount of ink by a method wherein a width in a direction parallel to a nozzle forming substrate of a pressure generating component is so constructed not to be uniform. CONSTITUTION:When applicable voltage 16 is impressed to a pressure generating component 13, the pressure generating component is displaced to the arrow 22 side, and an ink drop 20 is discharged from a nozzle 14. When a shape of a section A-A of the pressure generating component 13 is taken as a T character form likely to have a thick root part and a thin top part, since inertia moment around the root of the pressure generating component 13 is decreased and resilience as a beam is improved, natural oscillating frequency of the pressure generating component 13 is shortened. Therefore, ink discharge interval time can be decreased, and response property in frequency is increased. Since the pressure generating component 13 is deformed by equal moment, when a maximum value of applicable voltage 16 is constant, displacement at a top of the pressure generating component 13 is constant irrespective of a shape of the pressure generating component 13 at the section A-A, and the discharge speed and discharge amount of the ink are hardly varied.

IPC: H02P9/04
Filed: 1988-04-22
Abstract: PURPOSE:To maintain the generating power of a generator at maximum power at all times by sequentially altering a speed command value to a higher speed value when the generated power tends to increase, and temporarily altering the command value to a low speed value when the generated power is shifted from the increasing trend to a decreasing trend.

Here, a speed instructing circuit 10 sequentially alters a speed command signal to a high speed value when the generated power detected by a generated power detector 16 tends to increase, and temporarily alters the command signal to a low speed value when the detected power is shifted from the increasing trend to a decreasing trend, and then again returns the speed command signal to the high speed value. Thus, the efficiency of a generation system can be maximized.
