Title: Interchange type variable power lens
Inventor: KUDO YOSHINOBU
IPC: G02B15/08
Filed: 1987-11-13
Abstract: PURPOSE:To change the focal length of the entire system by providing a front group and rear group having a positive refracting power to the title lens system and moving the front group in an optical axis direction, then interchange the rear group with an auxiliary lens group having the refracting power different from the refracting power of the rear group. CONSTITUTION:A telephoto type is used in order to obtain a main lens of a short overall length. This lens system is divided to the front group I and rear group II having the positive refracting power and the front group I is moved in the optical axis direction; in addition, the rear group II is interchanged with the auxiliary lens group III having the refracting power different from the refracting power of the rear group II. The fluctuation in the aberration when the auxiliary lens group III is inserted is decreased and the constitution of the rear group II with a smaller number of lens elements is enabled if a stop is disposed between the front group I and the rear group II and is moved together with the front group I on the optical axis. The overall length of the main lens is thereby shortened and the focal length is changeable while the good aberration performance is maintained.

Title: Drum heater
Inventor: ENDO HIDEKI
IPC: G03G15/00
Filed: 1988-11-15
Abstract: PURPOSE:To shorten a time lag continuing until a change is compensated by allowing an infrared ray absorbing coating applied on the interior of a photosensitive drum to absorb infrared rays emitted from an infrared heater. CONSTITUTION:The infrared heater 1 is provided so that it is fixed on the rotational, central axis of photosensitive drum 4. Its internal surface is coated with the infrared ray absorbing coating 2, and a temperature sensor 5 composed of a thermistor, etc., is provided to be close to the external surface of the drum as much as possible.

Title: Cooling device of vehicle
Inventor: SUZUKI KAZUKI
IPC: F01P7/02
Filed: 1989-11-06
Abstract: PURPOSE:To execute cooling performance always appropriately for a wide range of vehicle speed by a method wherein a forward tilting angle of a cooler is so controlled as to suppress a draft resistance in accordance with a flowing condition of an outside air current. CONSTITUTION:An outside air current A flows into a condenser 40 and a radiator 30, while being displaced upward in accordance with a vehicle speed increase, through operation of an axial flow fan 60. When a microcomputer 130 generates a duty opening degree output signal in accordance with the vehicle speed detected by a vehicle speed sensor 90, a drive circuit 140 drives a solenoid valve 80 to generate a negative pressure and a negative pressure actuator 70 tilts the radiator 30 forward. Accordingly, a forward tilt angle of the radiator 30 increases in proportion to the vehicle speed and the outside air current A thereby flows in always nearly orthogonaly to the front surfaces of the condenser 40 and the radiator 30. The draft resistance caused by the inflow of outside air current A is therefore suppressed to a minimum value and a heat radiation effect of the condenser 40 and the radiator 30 is sufficiently secured for a wide range of the vehicle speed.

Title: Memory error detecting system
Inventor: MAEKAWA NORIAKI
IPC: G06F12/16
Filed: 1988-11-15
Abstract: PURPOSE:To early recover the error of the memory contents by detecting the occurrence of the error and at the same time holding the address signal value. CONSTITUTION:In the case one of memory chips 3a - 3n has a memory error, an error detecting circuit 7 detects the error and produces an error detection signal. Then an address latch circuit 8 performs a latching operation to latch the address signal (showing a reading address at occurrence of an error) outputted from an address expanding circuit 6. At the same time, the circuit 8 supplies the latched address signal to other circuits of a CPU 1, a decoder, etc., via a gate circuit 9. Thus it is possible to detect the occurrence of a memory error in a simple constitution and also to decide a specific memory chip that is produced an error. Then the error can be early recovered.

Inventor: HIRAMA HIDEO
IPC: H02N2/00
Filed: 1992-10-27
Abstract: PURPOSE:To attain high torque, without increasing spring pressure, through simple increase of the thickness of an oscillator while keeping the outer diameter thereof constant by employing a structure where two ultrasonic motors are opposed each other. CONSTITUTION:Ultrasonic oscillation generated from piezoelectric elements 3, 4 induces a traveling wave in the circumferential direction of oscillators 5, 6 and movers 9, 10 are rotated through protrusions 19, 20 and liners 7, 8 contacting therewith.
