Patent JP-H01278787-A (JP)
Title: Method and apparatus for stabilizing temperature of optical device
Inventor: ONAKA HIROSHI
IPC: H01S5/024
Filed: 1988-05-02
Abstract: PURPOSE:To prevent the occurrence of a temperature drift with a comparatively simple structure by a method wherein a part or all of an oscillation circuit is provided in one piece with a member, an oscillation frequency of the oscillation circuit is so controlled as to make the oscillation frequency constant. CONSTITUTION:A device is composed of a member 1 which releases or absorbs heat corresponding to a flowing current, an optical component 2 attached to the member 1, an oscillation circuit 3 which is wholly or partially provided in one piece with the member 1, a means which detects the oscillation frequency of the oscillation circuit 3, and a means 5 which controls a flowing current so as to make the oscillation frequency constant. And, the temperature of the member 1 is detected as the change of an oscillation frequency which changes corresponding to the temperature change of the member 1. A temperature drift, which used to become a problem generally, appears primarily as a voltage change. By these processes, a temperature change is converted into a frequency change, which is fed back as a control parameter, whereby the effect of a temperature drift can be canceled.

Patent JP-H06315449-A (JP)
Title: Dish washer
Inventor: OSHIMA SHIN
IPC: A47L15/42
Filed: 1994-04-21
Abstract: PURPOSE:To prevent pollution of water for washing at the time of rinsing, by providing a bypass route for disconnecting a filter from a circulation route and a means for blocking one of the circulation route and the bypass route, and by closing the bypass route at the time of preliminary washing so as to pass the water through the filter, while closing the circulation route at the time of rinsing so as not to pass the water through the filter. CONSTITUTION:In preliminary washing, a pump 9 is actuated to turn clockwise, and water for washing is spouted from a spout nozzle 7 to wash tablewares in a vessel 2. At the same time, a heater 13 inside a blast pipe 12 in a wash tank 15 ventilated by a fan 19 heats the water for washing as well as the air inside the vessel 2. When the preliminary washing is finished, a motor 8 is actuated to turn counter clockwise. This drains polluted water, and the hydraulic pressure caused thereby elevates a piston 19 inside a drainage pipe 6, so that a bypass cover 16 is pushed up to open the bypass route. Thus, the water used in preliminary washing enters the filter 22, and, after being filtrated, enters a washing tank 15. This water is sucked and spouted for rinsing. This drainage water does not pass through the filter 22 but flows in the bypass route.

Inventor: FURUMIYA MASAAKI
IPC: G11B7/09
Filed: 1992-04-27
Abstract: PURPOSE:To prevent the occurrence of focus offset and track offset even when the fluctuation of the wavelength of a light source occurs by prolonging the separation line of a photodetecting element in the same direction as a beam spot or in the direction of a specified angle. CONSTITUTION:Since a beam made incident on the photodetector PD 4-2 and PD 5-2 is + or -1st-order beams diffracted by a hologram element 2 and a zeroth order beam transmitting the hologram element 3, when the wavelength fluctuation occurs in a laser diode LD 9, the beam spot is moved in the direction of an arrow G. But, since the separation lines of the photode-tectors PD 4-2, PD 5-2 coincide with the moving direction of the beam spot, no focus offset occurs. Further, since the beam spots made incident on the tracking error signal detecting photodetectors PD 4-1, 4-3 and PD 5-1, 5-3 are the + or -1st-order beams of the element 2 and also the + or -1st-order beams of the element 3, when the wavelength fluctuation occurs in the LD 9, the beam spots are deviated in the direction of a diagonal deviated by 45 deg. and no track offset occurs.

Title: Surface inspecting device
Inventor: TAKEUCHI MUNEAKI
IPC: G01N21/892
Filed: 1982-06-21
Abstract: PURPOSE:To judge the major defect accurately even in the case of discontinuous defects, by detecting the total length from the beginning of the defects to their end, and judging the result as the major defect when the difference between the total length and accumulated length is larger than a specified value. CONSTITUTION:The defect signal, which is optically detected by a sensor 1, is inputted to a counter 12 through an amplifier 5, a waveform shaping circuit 6, a comparator circuit 7, and a gate circuit 8. A pulse is generated by a pulse generator 4 every time a plate to be checked 3 is moved by unit length. The pulse is inputted to a defect interrupt detecting counter 10, which is controlled by an FF circuit 9. When the counted value reaches a preset value 11, the data in the counter 12 is latched by a latch circuit 13. Meanwhile, a total length counter 16 counts the input pulses during the period an FF circuit 15 is set. When the difference between the value, which is obtained by subtracting a preset value l from the total length of a latch circuit 17, and the accumulated length from the latch circuit 13 is larger than a preset value (k), a microcomputer 14 jusdges the result as the major defect.

Title: Telephone line automatic equalizer
Inventor: UEMURA TAKUYA
IPC: H04B3/06
Filed: 1991-04-15
Abstract: PURPOSE:To save the time and labor replacing an equalizer by compensating a line loss automatically in response to the length of a telephone line even when the length is revised. CONSTITUTION:The speech current of a telephone set 4 flows through a telephone line 3 from an output terminal 1. The speech current in changed with the distance of the telephone line 3 and the magnitude of the current is detected by a detector 5. The detection signal of the detector 5 is inverted by a signal inverter 6 and since the signal controls the amplification factor of a variable amplifier 7, the amplified quantity is changed almost inversely proportional to the ampltude of the speech surrent. That is, when the length of the telephone line 3 is long, the loss of the line is large and the speech current is small, the amplification factor of the variable amplifier 7 is increased. Conversely, when the length of the telephone line 3 is small, the loss of the line is small and the speech current is large, the amplification factor of the variable amplifier 7 is decreased. Thus, even when the length of the telephone line 3 is revised, the speech current is controlled almost constant automatically, thereby keeping the speech sound volume constant.
