Title: Temperature controller having liquid level detecting function
Inventor: BABA TETSUO
IPC: G01K7/36
Filed: 1982-08-14
Abstract: PURPOSE:To obtain a device having a liquid level display function which interlocks a temperature control circuit and displays the liquid level even at night, by providing a temperature-sensitive element which delivers voltage signals different by the fluctuation of a prescribed temperature, a float made of a magnetic matter and floating on the liquid level, etc. CONSTITUTION:A temperature sensitive element delivers voltage signals different by the fluctuation of a prescribed temperature, and a float made of a magnetic matter is put on the surface of a liquid. For instance, if a float 5 of a tank 1 is set at the position of an empty water detecting transformer coil 4 set at the detecting position for empty water, a light emitting diode (empty) for display of empty water is switched on. Then the LED (full) for display of full water is switched on when the float 5 is set at the position of a transformer coil 3. When the float 5 is set at the middle between transformers 3 and 4, both LEDs (empty and full) are turned off. Then an LED (medium) showing that the liquid is set at a medium level. The voltage output of a temperature sensor 6 changes with a rise of temperature. Thus a bilateral 3-terminal thyristor is turned off to discontinue the supply of a current to a load.

Title: Image forming apparatus
Inventor: SERIZAWA YOJI
IPC: G06F3/12
Filed: 1995-06-07
Abstract: PURPOSE: To simply detect the change of the state of a printer engine. CONSTITUTION: An engine control part 202 investigates the respective parts of a printer and, when there is a change state, the engine control part 202 forms a status STATUS 2 representing the change state and outputs a/CNFG signal to a controller 201. The controller 201 knows the change state from the/CNFG signal and reads the STATUS 2 to investigate which state is changed. When the change state is cleared, this state is read to know a present state. Therefore, it becomes unnecessary to read a state periodically to investigate the same and image forming processing can be made efficient.

Abstract: PROBLEM TO BE SOLVED: To provide an automatic gain control(AGC) circuit with which the circuit scale of a resistor to control the gain is suppressed and control accuracy is improved. SOLUTION: When an upper limit set voltage (u) and a lower limit set voltage (d) of a prescribed amplitude area are continuously exceeded within one cycle of output of a comparator 4, an upper limit detecting signal CMP/U and a lower limit detecting signal CMP/D are continuously outputted from an upper limit comparator circuit 7 and a lower limit comparator circuit 8 and continuously held by D flip-flop circuits 15 and 20.

Filed: 1980-10-08
Abstract: PURPOSE:To find the occurrence, a position, and a size of a breakage in a flexible film, by a method wherein a photo fiber is attached to a flexible film, and it is detected that a photo fiber, simultaneously, breaks when the flexible film is broken down. CONSTITUTION:A photo fiber 2 is caused to trail over a flexible film 1 by attaching the photo fiber 2 to the surface of the flexible film 1 or by placing the photo fiber 2 in the flexible film 1. If tearting, wearing, or breaking of the flexible film occurs, the photo fiber 2, trailing over the flexible film 2, is concurrently broken down. Thus, the disappearance of a reflection light cut surface of the photo fiber permits the estimation of a breakage position. A numeral 3 is a light-emitter, 4, 4'  are light-receivers, 5 is an incident light, and 6 is a reflection light. A plurality of  the photo fibers 2 are placed in a grating or in the proximity of each other and this enables the estimation of even a size of a breakage.

Title: Arc spot welding of thin plate structure
Inventor: SHIMADA WATARU
IPC: B23K9/007
Filed: 1977-11-26
Abstract: PURPOSE: To enhance the reliability of welding by preventing the deformation of thin plate structure by procedure in which arc spot welding torch is put on the reingorcing material side with perforated hole and welding is made while cooling it from the side of outside plate.  
     CONSTITUTION: The perforated hole 5 having a fixed diameter determined by the thickness of the outside plate 1 is bored at a point to be welded of the reinforcing matrial 2. The reinforcing material 2 and the outside plate 1 are combined, the arc spot welding torch 3 is put on the side of the reinforcing material 2, and the cooler 6 is symmetrically arranged on the side of the outside plate 1. When welding is made in this state, the perforated hole 5 is filled up with weld metal and thus the outisde plate 1 and the reinforcing plate 2 are exactly weded in a short time. And, the presenc of the perforated hole 5 reduces the amount of weld metal, so that the deformation of weld due to the coagulating contraction of theweld metal is smaller. In addition, the temperature rise of the outside plate 1 by welding heat can be suppressed by the cooler 6, and thus the deformation of weld can furthermore be reduced, raising the reliability of arc spot welding.

Abstract: PURPOSE:To realize the waveform shaping with high accuracy and to improve the error rate by providing a waveform shaping means consisting of a combination of a waveform equalizing means for compensating a peak of a regenerative signal and a false eliminating means for eliminating a false pulse of the regenerative signal. CONSTITUTION:The regenerative signal read by a read/write head 21 is amplified by an amplifier 22, and is afterward waveform-shaped by a waveform equalizing circuit 27, so that a peak of the regenerative signal is compensated. The regenerative signal wave-formed by the waveform equalizing circuit 27 is inputted to a false pulse eliminating circuit 31. In this false pulse eliminating circuit 31, an input waveform is delayed by a delay line 28 by tau, and its amplitude is adjusted to be K times by a gain adjusting resistor 29 to generate a delay waveform, and this is synchronized with the input waveform by a differential amplifier 30, thus performing the waveform shaping by way of eliminating the false pulse of the input waveform. By this method, lowering of the level of the regenerative signal and lowering of a margin due to an effect such as a peak shift, etc., can be prevented, while erroneous detection of the signal due to the generated false pulse is prevented so that the error rate of the device can be improved.
