Title: Control device for refrigerator
IPC: F25D17/08
Filed: 1992-03-24
Abstract: PURPOSE:To prevent production of an uncomfortable feeling owing to gear generating noise of a damper and vibration noise of a motor by providing a means which delays the operation of a damper by a given time during opening of a door, in a refrigerator provided with a detecting means to detect opening and closing of the door and the damper to perform regulation of temperature in a chamber. CONSTITUTION:A freezer refrigerator comprises a fan 3 to circulate cold air cooled by means of a cooler 2, a damper 6 to control cold air to a refrigerating chamber 4 by opening and closing an air duct 5 through which a part of cold air is guided to the refrigerating chamber 4, and a door detector 11 to detect opening and closing of the door. The damper 6 is controlled by a control means 15 according to the detected output of a thermistor 8 to detect temperature in a freezing chamber 9 and a refrigerating chamber 4. In this case, when opening of the door is detected by the door detector 11, control is effected so that operation of the damper 6 is delayed by a given time. This constitution prevents a user from hearing gear generating noise of the damper 6 and vibration noise of a motor when the door is opened.

Title: Optical communication system
Inventor: WATANABE AKISADA
IPC: H04B10/50
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a WDM optical communication system constitution appropriate for using an LED as a light-emitting light source. SOLUTION: This system is constituted by optically connecting a photodetector 9 for receiving the signal light and the LED 11 to be a light source of transmission light to a variable wavelength type branching filter 6 for selecting arbitrary wavelength signal light from wavelength multiplexed signal light 4 in a reception station 12, provided with the transmission/reception function of optical signals together. A demultiplexer 3 for connecting the light waveguide of a private branch wiring from the plural reception stations also functions as a multiplexer, and it is desirable to provide a bidirectional light amplifier 2 on a channel side.  Thus, since an inexpensive LED is used as the light source and the light of arbitrary wavelength is selected from the wide light-emitting spectrums of the LED by the variable wavelength branching filter, the need for stabilizing the light-emitting wavelength of the light source is eliminated, the need for a temperature controller required for that is eliminated and cost is reduced. Moreover, since the wavelength of reception light and the wavelength of the transmission light may be automatically made identical or set with a fixed difference, the constitution of the system is simplified.

Title: Automatic retrial dial system
Inventor: AOTANI YOSHIHISA
IPC: H04M1/27
Filed: 1988-03-18
Abstract: PURPOSE:To reduce number of times of retrial dialing by allowing a modulator- demodulator being an incoming side to extract a telephone number of the modulator-demodulator of the opposite party stored in the internal memory and to apply dialing thereby calling the modulator-demodulator of the opposite side after a prescribed time elapses from the interruption of line. CONSTITUTION:When a line connecting exchanges 3, 4 is a line with large deterioration, a modulator-demodulator 1 detects it by a data quality (SQD) signal to interrupt the line. Since a carrier detect(CD) signal is reset when the modulator-demodulator 1 interrupts the like, a modulator-demodulator 2 detects it to interrupt the line. Then the modulator-demodulator 2 being an incoming side extracts the telephone number of the modulator-demodulator 1 from the internal memory and makes dialing after the interruption of line to call the modulator-demodulator 1. Thus, the other transmission line is selected between the exchanges 3, 4 and when the deterioration of the line is less, the said line is used for data communication.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To restrain hole injection from a base layer to an emitter layer, and restrict conductivity modulation of a ballast layer which causes deterioration of temperature characteristics. SOLUTION: An HBT has an n-type AlxGa1-xAs ballast layer (0<=x<=0.45) 24, and an emitter layer is made a double structure of an n-type AlGaAs emitter layer 25 and an n-type InGaP emitter layer 26, and an InGaP/GaAs heterojunction is formed in between relative to a p+-type GaAs base layer 27. Thus, energy ΔEv of the valence electron band of the InGaP/GaAs heterojunction is set at 280 meV, and the injection of holes from the base layer 27 to the emitter layer 25 is restrained at high temperature and at high current density. As a result, even at high temperatures and high current density, effects of the n-type AlGaAs ballast layer 24 will not be hindered, and uniformity in satisfactory current and temperature can be attained.

IPC: G11B5/008
Filed: 1987-03-20
Abstract: PURPOSE:To prevent disturbance of pattern and crosstalk by controlling the running speed of a tape so that the deviation of horizontal synchronization between tracks is a half of a natural odd number and recording a television signal so that the television signal of the latter half of one field is retarded by 1/2 of the horizontal synchronizing period. CONSTITUTION:The tape running speed is controlled so that the deviation of horizontal synchronization between tracks formed at each other interval of the track formed on the tape is to be a half of a natural odd number at recording and the television signal at the latter half of one field is retarded by 1/2 of the horizontal synchronizing period and the result is recorded on the tape at recording. The first half of one field in the television signal is retarded by 1/2 of the horizontal synchronizing period at reproduction to match the phase with the horizontal synchronizing signal of the latter half of one field. Thus, the disturbance in the picture of joints of signals at the middle part of the reproduced pattern or pattern disturbance due to crosstalk from adjacent track is avoided.
