IPC: H04L69/40
Filed: 1982-11-01
Abstract: PURPOSE:To allow an optional modem to test another modem by inhibiting the operation of one circuit when the other circuit which detect test start signals from receive and transmit data once detects a start signal. CONSTITUTION:When a modem 3 tests a modem 5, the modem 3 sends a test start signal to a communication circuit 7. This signal is inputted to the test signal detecting circuit 12 of a modem 4 and sent to a control circuit 16. The control circuit 16 inhibits a test signal detecting circuit 15 from operating. Similarly, modems 5 and 6 are handled similarly. Then, the modem 3 sends the number of the modem 5 to be tested and the circuit 15 of the modem 5 when detecting the signal reports it to the circuit 16. The circuit 16 energizes a relay 17 to instruct a test signal generating circuit 11 to send an answer signal, and the circuit 11 sends the answer signal to the modem 3. The modem 3 receives the signal, and judges that the device 5 enter a loop-back state, thereby executing the test.

Title: Remote control system
Inventor: NISHIO MASAAKI
IPC: H04Q9/00
Filed: 1987-07-31
Abstract: PURPOSE:To attain a correct remote control by prohibiting that a remote control signal is transmitted by itself when other remote control unit transmits a signal judging from the output of a pair of receiving circuits. CONSTITUTION:Transmission circuits 12 and 22 respectively control light emitting diodes 14 and 24 and the light emitting diodes 14 and 24 emit an infrared- ray signal in which a carrier frequency is f0 as a remote control signal. At such a time, control circuits 11 and 21 emit the infrared-ray signal after it is confirmed that receiving circuits 13 and 23 do not receive the signal. The infrared-ray signal goes to an acknowledgment signal to a transmitting/receiving unit 1 or a transmitting/receiving unit 2 to emit the infrared-ray signal and goes to an infrared-ray signal emission prohibiting signal to the transmitting/ receiving unit 1 or the transmitting/receiving unit 2 not to emit the infrared-ray signal. Even when plural remote control units are used, a correct remote control can be executed without the competition between remote control units.

Title: Method of working semiconductor substrate
Inventor: MANABE MASAMICHI
IPC: H01L21/027
Filed: 1984-09-13
Abstract: PURPOSE:To accurately form both main surfaces of a semiconductor substrate without using an expensive device by opening a through hole at the substrate by anisotropically etching, and forming the both main surfaces of the substrate with the hole as a working reference position. CONSTITUTION:Silicon nitride films 2a, 2b of approx. 1,000Angstrom of thickness formed both main surfaces 1a, 1b of a silicon substrate 1 having 100 azimuth and 400mum of thickness are provided, and at least two positions of the film 2a are multiple-exposed by a projecting exposure unit to forma square hole 3 for anisotropically etching. The substrate 1 is dipped in KOH aqueous solution of approx. 40% of concentration to etch the substrate 1. At this time, since the etching velocity at the 100 surface is as fast as aprox. 400 times as compared with the 111 surface, the etching in the vertical direction to the main surface of the substrate 1 becomes positive to form a through hole 4. The etching amount in the direction parallel to the main surface of the substrate 1 of approx. 400mum of thickness is too small to be ignored in the working of approx. 1mu.

Title: Line sequence discrimination circuit
Inventor: KURIBAYASHI MICHIO
IPC: H04N9/86
Filed: 1983-10-15
Abstract: PURPOSE:To eliminate almost the delay of discrimination in comparison with the discrimination by frequency difference with a filter by comparing a potential just after a clamped horizontal blanking period with a reference value so as to discriminate kinds of a color difference signal. CONSTITUTION:A frequency division circuit 27 inputs a pulse MD at each horizontal scanning period and divides it into 1/2, a clamp pulse generating circuit 30 is triggered in synchronizing with an output signal of the circuit 27, a clamp pulse CP is outputted in the horizontal blanking period HBLK and a clamp circuit 22 clamps a line sequential chrominaice signal. A sampling circuit 23 samples said signal at a period just after the clamped period HBLK at least among the periods HBLK. A reset pulse generating circuit 25 compares each sample value with a reference value and when the value satisfies a prescribed condition, a reset pulse RP is outputted so as to reset the circuit 27. Thus, a discrimination signal ID is obtained from said circuit 27.

Title: Semiconductor device and fabrication thereof
Inventor: KOTANI NAOKI
IPC: H01L29/732
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device provided with a bipolar transistor suitable for high frequency having stabilized emitter-base breakdown strength and high frequency characteristics, and a fabrication method thereof. SOLUTION: After native oxide film on a substrate is removed thoroughly by dip etch, a wafer is thrown in at a low temperature of about 400 deg.C and an amorphous silicon film is deposited under a state where oxide film is not present on the surface of the substrate. A base electrode 43 is then formed by patterning and impurities in the base electrode 43 are diffused into the substrate thus forming an external base diffusion layer 41a. Subsequently, an intrinsic base diffusion layer is formed by ion implantation and an emitter diffusion layer 42 is formed by impurity diffusion from an emitter electrode 45. Since an oxide film between the base electrode 43 and the substrate can be reduced, spreading of the external base diffusion layer 41a due to impurity diffusion can be suppressed resulting in the enhancement of emitter-base breakdown strength and high frequency characteristics.

Then, the film 105 is removed; the groove 106 is filled with an insulator 107; after that, an etching-resistant film 108 is formed; a vertical groove is formed by an anisotropic etching method; an insulator is filled. Thereby, an element region composed of single-crystal silicon 111 is separated electrically from the substrate 101. Since a high-temperature heating operation is not required in this manner, a deterioration of an element characteristic can be eliminated.

Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To provide an audio device for listening to a music even in a noisy situation in the same way as a situation that there is not any noise as much as possible. SOLUTION: A gain/signal characteristics in various kinds of noise levels are preliminarily stored in a memory MM of a loudness compensation gain calculating part 8. A noise signal is separated from the output of a microphone 7 by a signal separating part 6, and inputted to the loudness compensation gain calculating part 8 with a music signal. The loudness compensation gain calculating part 8 wavelet converts those signals, and detects the level for each frequency band, and calculates the optimal gain for each frequency band by referring to the gain/signal characteristics stored in the memory MM, and sets it at a filter 3 for correction. The filter 3 for correction adds the gain to the music signal, and supplies it to a loudspeaker 5.

Title: Light quantity control diaphragm
Inventor: MORO SHUJI
IPC: G03B9/02
Filed: 1994-07-25
Abstract: PURPOSE:To make the constitution of a device simple and compact and to easily drive a diaphragm blade by constituting an electrostatic actuator for driving the diaphragm blade of a high resistor and an electrode part. CONSTITUTION:When voltage is impressed on the desired electrode of the respective electrode parts 25 and 26 from the outside through a cable, induced charge is charged to the spots of the high resistor parts 23c and 24c of the diaphragm blades 23 and 24 disposed to be opposed to the electrode parts 25 and 26 corresponding to the electrode. By switching the polarity of the electrode, thereafter, the induced charge charged to the corresponding spots of the high resistor parts 23c and 24c remains where it is without moving in the high resistor parts 23c and 24c because the high resistor parts 23c and 24c are high resistance. Therefore, the induced charge is attracted to the electrode whose polarity is switched. Thus, the high resistor parts 23c and 24c of the blades 23 and 24 move in the direction of an arrow X against the tensile force of a tension spring 27 so as to move the blades 23 and 211 in the direction of the arrow X.
