IPC: G10H1/057
Filed: 1992-03-19
Abstract: PURPOSE:To obtain a sound generating device of simple constitution which give depth and weight close to a natural sound to a timbre. CONSTITUTION:When a pulse is inputted to a terminal A to reset a signal generating circuit 2 and frequency dividers 12 and 13, the signal generating circuit 2 reads a frequency division ratio from a pitch control signal and sets it and a fundamental frequency generating circuit 1 generates a set pitch signal F1. A control circuit 11 puts switching circuits 5 and 6 in operation corresponding to the frequency of the pitch signal F1 to charge and discharge a capacitor 4 and an envelope signal containing a beat component is outputted to a multiplying circuit 20. The multiplying circuit 20 generates a sound signal composed of the pitch signal F1 and the envelope signal containing the beat component to output a sound from a speaker 22 through an amplifier 21.

Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To automatically set an optimum output channel of an RF converter even in the case of a tuning system for a television signal adopting voltage control. SOLUTION: The television signal receiver is provided with a tuner and intermediate frequency amplifier circuit 4 that automatically selects a channel where a broadcast station signal is present from a received television signal by means of a voltage control system and with an RF converter 6 that converts a video signal and an audio signal of the selected channel where a broadcast station signal is present into an RF signal and outputs the RF signal based on the output of the circuit 4.  Then a microcomputer 1 outputs sequentially a pulse width modulation PWM signal with a value corresponding to a voltage to select each channel to allow an automatic channel selector to sequentially select each channel where a broadcast station signal is present and to detect channels where broadcast station signals are not in existence over a prescribed channel number, obtains a value of a PWM signal corresponding to a voltage to select an intermediate channel and sets an output channel of the RF converter 6 based on the value of the obtained PWM signal.

Title: Recording system of electronic device
Inventor: YOSHINAGA YOSHIO
IPC: G06Q40/02
Filed: 1984-03-31
Abstract: PURPOSE:To judge the recording condition of recorded data of a PROM by reading recorded data, and collating them with data from the outside, and recording flag bits showing the collated result. CONSTITUTION:An IC card 1 as an electronic device incorporates an IC chip and a connector part 3, and the former consists of a microprocessor MPU4 and a PROM5 for recording the data processed by the MPU4. When a telegram consisting of a recording command code, a zone name of the PROM5 and recorded data is given to the IC card 1 from a reader/writer, it is stored in a RAM9 through the connector part 3 and a control part 6 of the MPU4. Then the control part 6 checks a flag consisting of two bits in the PROM5, discriminates whether the flag is nonrecording or effective recording of data, recording errors, or test recording; records the data stored in RAM9 from an address next to the address, where the final word is effective, to the PROM5, reads the recorded data after the recording is finished, and finally records the collated result with input data in the flag.

Title: Control system for automobile wiper
Inventor: TORII SHIYUUICHI
IPC: B60S1/08
Filed: 1979-05-25
Abstract: PURPOSE: To drive a wiper with the wiping motion most suitable for an automobile, by changing the cycle of its wiping motion in accordance wth the amount of rainfall or the car speed.  
     CONSTITUTION: A driving circuit for a motor M for driving a wiper has in series a load current detecting device 2. Output of a load current detecting device 2 is input to a wiper motor driving circuit 1 through an intermittent control switch SW 1 . In this arrangement, the load current to the motor M increases and the time for the wiper to begin the next wiping motion becomes longer when the amount of rainfall is small, because this makes the load for the wiper to wipe the front glass heavier. On the other hand, when there is a large amount of rainfall, the load of the wiper becomes smaller, which makes the load current to the motor M decrease and the time for the wiper to begin the next wiping becomes shorter. The wiper, therefore, can operate intermittently according to the amount of rainfall, giving the most suitable wiping motion to the automobile.

IPC: H01L21/02
Filed: 1995-02-27
Abstract: PURPOSE: To chamfer a semiconductor wafer at a stable high yield and, at the same time, to detect the optimum values of cutting conditions. CONSTITUTION: A semiconductor wafer is chamfered by sliding a chamfering wheel 12 rotated by means of a motor 14 incontact with the outer peripheral section of the wafer. During the chamfering operation, an ammeter 17 and voltmeter 18 continuously measure the load of the motor 14 and a controller 16 detects the pattern of the measured values. The controller 16 also detects abnormal chamfering by comparing the detected pattern with a normal pattern and, upon detecting abnormal chamfering, takes a necessary measure. When, for example, the chamfering wheel 12 becomes abnormal, the controller 16 makes the grinding surface of the wheel 12 to be automatically dressed. When wafer chipping occurs, the controller 16 makes the surface of a diamond grinding wheel to be automatically dressed and checks the material lot.  When the rotating speed of the wheel 12 fluctuates, the controller 16 checks the rotating system of the motor 14. When the rotating speed of the wafer fluctuates, the controller 16 checks the rotating speed of the wafer.
