Title: Power supply circuit
Inventor: SUGIMOTO SATOSHI
IPC: H02M3/28
Filed: 1994-05-31
Abstract: PURPOSE:To prevent a failure of a switching transistor due to overcurrent by providing a photocoupler capable of forcibly turning off first and second switching transistors when a detecting circuit detects an overcurrent. CONSTITUTION:In a moment when a power supply to a circuit is turned on, excessive currents flow to first and second switching transistors Q11 and Q12 and a primary coil L13. An excessive current flowing to the primary coil L13 flows to the primary coil CT1 of a current transformer CT, by which an induced electromotive force is induced to a coil CT2 at secondary side and rectified by a rectifier circuit 15A and a detected voltage Vs is created and input to a comparator circuit 15B at which a comparing processing is performed between the detected voltage Vs and a reference voltage Vref. If an excessive current flows, a light emitting diode(LED) of photocouplers PC1 and PC2 are lighted, and the first and second switching transistors Q11 and Q12 are turned off. As a result, failure of switching transistors can be suppressed.

IPC: H03K5/153
Filed: 1985-05-31
Abstract: PURPOSE:To change a voltage division ratio to detect plural voltages by feeding back contents of a comparison output storage part to a voltage dividing part of the input. CONSTITUTION:When a comparison output storage part 10 is cleared in the system initial state, contents of the cleared output storage part 10 are discriminated by a division ratio setting control part 11 to issue a control signal which sets setting variable switches of a variable voltage dividing part 7 to the initial state, and the voltage detection value is initialized in these procedures. When the voltage of a voltage line 6' to be detected reaches the detection value after initialization, a detection signal is issued from a comparing part 8 and is taken into the comparison output storage part 10 capable of successive storage, and the control output of the division ratio setting control part 11 is changed in accordance with the change of stored contents, and turn-on/off of setting variable switches of the variable voltage dividing part 7 is changed to set the next voltage detection value. This operation is repeated to change the voltage detection level in order. Thus, plural voltage levels can be detected.

Inventor: TSUBAKI MASAMITSU
IPC: H04N1/40
Filed: 1982-07-08
Abstract: PURPOSE:To obtain a facsimile character recognizer which has the reduced probability for incapability of character recognition and a short transmitting time, by varying selectively the linear density of the picture signal which is transmitted via a communication circuit. CONSTITUTION:When an input original is read by a scanner 202 with the highest linear density, the surface information is transferred to a compressing/expanding circuit 216 by a linear density selecting circuit 204 and then coded to be stored in a memory 210. The picture signal sent to a compressing/expanding circuit 206 undergoes band compression and is transmitted to a facsimile receiving device 300 from an MODEM208 through a circuit 100. The picture signal received at an MODEM308 is expanded by a compressing/expanding circuit 306 to be decoded to the original raster scanning picture signal and transmitted to a character recognizer 400. When a character which cannot be recognized by the recognizer 400 is detected, the recognition is discontinued. Then the generation of the recognition unable character is informed to the circuit 306. A facsimile transmitting device 200 receives the signal from the circuit 306 through the MODEM 208, and this signal is discriminated by the circuit 206. The circuit 206 informs the generation of the recongnition unable character to the circuit 204 through a signal line 212.

Title: Frequency dividing circuit
Inventor: ASHITA HIDEO
IPC: H03B19/16
Filed: 1980-08-29
Abstract: PURPOSE:To obtain a broad band and stable operation with simple constitution by composing a higher-harmonic generator of a rectifying circuit. CONSTITUTION:When a higher-harmonic generator 15 is composed of a full-wave rectifying circuit, its rectification output is a frequency-doubled wave. Therefore, when an input frequency is f1 and an output frequency is f2, a band-pass filter 16 applies a signal of 2f2 to a frequency converter 12 to obtain a conversion output of a frequency f1+ or -2f2, and a band-pass filter 13 extracts an output frequency of frequency f1-2f2, i.e. f2=f1/3. Then, this output signal is amplified by an amplifier 14 and applied to the higher-harmonic generator 15, whose output is rectified to output a frequency-doubled output. Since the higher-harmonic generator 15 only performs rectification, it operates immediately after the application of the input signal and does not require synchronous oscillation, thereby widening its band.

Abstract: PURPOSE:To prevent the rear of a wafer from being plated and to prevent a crack during a grinding operation of the rear by a method wherein, before a plating operation is executed at a bump formation operation, a resin film is formed in a peripheral part of the wafer. CONSTITUTION:A wafer 1 is sucked to a spinner 2 and rotated to coat its peripheral part with a resin such as a photoresist, a electron beam resist or the like by using a brush squeezing the resin from a side face of the wafer 1. A resin film 3' is thus formed. During a posterior process, a bump is formed by a plating method of a jet stream system. The water 1 is placed on a claw 7 at the tip of a tube 6 in such a way that its surface is faced downward, and a plating liquid 8 is blown off from the upper part and is sprayed onto the surface of the wafer 1. However, it is possible to prevent the rear and the side face of the wafer 1 from being sprayed by the plating liquid 8 thanks to the resin film 3' formed at the peripheral part of the wafer 1. Then, the rear of the wafer is ground. Since the rear of the wafer is not plated, a grinding blade is not loaded and an incidence that the wafer is cracked is reduced remarkably.
