Title: Dynamic-random-access-memory
Inventor: SANGU FUU DONGU
IPC: G11C29/04
Filed: 1991-08-06
Abstract: PURPOSE: To prolong refresh interval by replacing a DRAM cell of a short data hold time with a redundant static memory cell. CONSTITUTION: Charges stored in capacity in the DRAM cell are discharged to an allowable level or below after a prescribed time interval T1 in many cells, and are discharged to the allowable level or below after a shorter time interval T2 in few cells. The refresh cycle of the DRAM is adjusted so as to become longer than the T2. This DRAM circuit contains plural redundant storage cells 50, a decoder receiving the addresses of the cells and a switch circuit. The decoder generates a first output when the receiving address is the address of the many cells, and generates a second output when the receiving address is the address of the few cells. The switch circuit allows to access the redundant storage cell in response to the first output to block the access of the few cells.

Title: High breakdown voltage output circuit
Inventor: ISHIOKA TAKESHI
IPC: H03K17/10
Filed: 1990-08-23
Abstract: PURPOSE:To make an output of the high breakdown voltage output circuit stable by keeping a gate electrode and a point of a 2nd reference potential to a prescribed voltage higher than a 1st power supply. CONSTITUTION:When an input signal is at an L level, a transistor(TR) 3 is turned on, a TR 4 is turned off and a signal with an H level closer to a power supply VDD is fed to a gate of a TR M2. The TR M2 is turned on through the application, a TR Q1 is turned on and a constant current flows from an emitter of the TR Q1 to a constant voltage diode D2. Thus, a prescribed voltage Vz set higher than the voltage of the power supply VDD is fed to the gate of the TR M2 and a drive current of the TR M2 is much increased. Thus, the output of the high breakdown voltage output circuit is made stable.

Title: Burner of vehicle burning heater
Inventor: ARAI KAZUMITSU
IPC: F23D5/04
Filed: 1988-09-02
Abstract: PURPOSE:To always hold the burning condition of a mixture good by attaching a porous member to a burning gas flowing-out opening of a burning cylinder. CONSTITUTION:After a high temperature burning gas is flowed through a porous member 8 and burning gas passages 24, 25, it is exhausted from an outlet 22a of an inner cylinder 22. Because the porous member 8 is attached to a burning gas flowing-out opening 4c of a burning cylinder 4 so as to partition off a burning chamber 3 and a burning gas passage 24, the burning gas of the burning chamber 3 is sent to the side of the burning gas passage 24 through the porous member 8. Since the porous member 8 has many minute holes 8a, ventilation resistance is small and the burning gas smoothly passes the porous member 8 through their holes 8. Further, since the porous member 8 is heated at a high temperature by a flame even if a unburnt gas is scattered, the unburnt gas surely burns when it flows through the holes 8a of the porous member 8. As the result, the burning condition of the burning chamber is always good and a noise is not generated by pulsation while soot does not adhere to the circumferential face of a burning cylinder 4.

Abstract: PURPOSE: To discriminate the kind of an optical disk with a simple constitution by converging luminous fluxes using a converging optical system corresponding to plural transparent boards having different thickness and detecting the diffracted light components in the luminous flux returned from the transparent boards. CONSTITUTION: When a cartridge 2, which contains a first or a second optical disk, is loaded to the device, an LED 8 emits a light and a photodiode 9 detects the presence or the absence of the transmission light which passes discrimination holes 7. When a transmission light is detected, a controller 13 judges the inner material of the loaded cartridge 2 to be a second optical disk and outputs a control signal to a servo circuit 11 so as to drive a second head 5 and a second linear motor 6. When the photodiode 9 detects no transmission light, the controller 13 judges the inner material of the cartridge 2 to be a first optical disk and outputs a control signal to the circuit 11 so as to drive a first optical head 3 and a first linear motor 4. Simultaneously, while the head 3 is in its operation, the controller 13 controls the motor 6 and the head 5 is retracted to the outer side of a disk surface.

Title: System and device for monitoring moving body
Inventor: UEHARA TERUAKI
IPC: G01S1/68
Filed: 1989-08-29
Abstract: PURPOSE:To monitor whether or not the moving body is within the specific range of the monitoring device by generating a reference signal and a disturbing signal. CONSTITUTION:This system consists of the monitoring device 100 and a moving device 200. In this case, the monitoring device 100 generates the reference signal and disturbing signal. The reference signal and disturbing signal have specific directivity respectively and at least a 1st area where the reference signal and disturbing signal can both be received and a 2nd area where only the reference signal can be received are formed. When the moving body 200 is in the 1st area, the reference signal and disturbing signal are both received, so the reference signal can not be decoded. When the moving body is in the 2nd area, only the reference signal is received, so the reception of the reference signal is sensed. Consequently, the moving body can senses the position about the monitoring device.

Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To improve the read-out performance of a signal by making the shape of a light spot formed on a disk circular and decreasing jitter. SOLUTION: A filter 10 for compensating the transmitting characteristic of a whole PBS 4 is provided on the surface of PBS 4 on which a light beam transmitted from a semiconductor laser 1 is made incident.

Consequently, the shape of the light spot formed on the disk 7 is circular.
