IPC: H01J31/10
Filed: 1980-10-25
Abstract: PURPOSE:To improve the assembling accuray of a bulb by splitting a cylindrical member axially into two while pre-applying a face plate and an end plate to each cylindrical member then sealing the open end face of each cylindrical member. CONSTITUTION:A cylindrical member is splitted axially into two thus to produce two cylindrical members 14a, 14b. A face plate 1 is applied to the first cylindrical member 14a through a frit glass 15 thus to form a sub-assembly (m) while an end plate 5 is applied to the second cylindrical member 14b thus to produce a subassembly (n). Thereafter two sub-assemblies (m), (n) are sealed into single assembly (bulb). Consequently the assembling accuracy of the bulb can be improved.

Title: Photodetector
Inventor: FUJIWARA ICHIRO
IPC: H01L31/107
Filed: 1989-06-14
Abstract: PURPOSE:To acquire enough sensitivity at a long wavelength band and to improve ionization rate of a multiplication layer by using a semiconductor material of a large mismatching of a lattice constant and by forming a photoabsorption layer and a carrier multiplication layer. CONSTITUTION:A material having enough sensitivity at a long wavelength band is used for a photoabsorption layer 6, and a material having a large ionization rate is used for a carrier multiplication layer 3. When a lattice constant of the multiplication layer 3 and that of the photoabsorption layer 6 do not match, a lattice constant of the multiplication layer 3 whereto high electric field is applied is matched to that of a substrate. A photoabsorption layer is laminated on an upper part of the multiplication layer holding a distortion super lattice 5 between them, whose effect is exhibited logically and experimentally. An avalanche photo diode(APD), where to a reverse bias voltage is applied, operates forming a depletion layer by a semiconductor layer. A signal light 12 which is rapidly modulated is absorbed in the photoabsorption layer 6, produces electron/hole as a photocarrier, transits inside the depletion layer and is injected to the multiplication layer 3. Thereby, it is possible to acquire a very high speed APD having enough sensitivity in a long wavelength band and a large ionization rate in a multiplication layer.

Title: Jack type rosette
Inventor: HOSOYA TSUTOMU
IPC: H04M1/738
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide the jack type rosette that is used in common independently of a communication network to which a user of a terminal subscribes. SOLUTION: Both 2-wire subscriber lines of a jack JA are bridged by a series circuit consisting of an inductor L, a capacitor C and a resistor R. The impedance Z of the series circuit with respect to its frequency (f) is expressed as Z=R+j(2πfL-X) by providing the series circuit as above to the jack JA, where X=1/2πfC. In the case of using the series circuit for a telephone network, the impedance of a 2nd term of the right side of the equation above is low at a telephone signal frequency. On the other hand, in the case of using the series circuit for an INS network, a 3rd term of the right side of the equation is negligible because the signal frequency is very high and the 2nd term shows a high impedance. Thus, the operation of the L, C, R series circuit is equivalent to that of an L, R series circuit.  Then the impedance of the L, C, R series circuit is high and the series circuit gives no much effect on signals transmitted in the INS network.

Filed: 1985-07-10
Abstract: PURPOSE:To prevent the flowing of overcurrents or transient currents through a semiconductor laser on the ON-OFF of a power supply or on the abnormality of a partial power supply by detecting the change of supply voltage within a range of supply voltage, in which a driving circuit for the semiconductor laser is operated under a stationary state, and controlling the currents of the semiconductor laser regardless of the operation of an automatic power control circuit. CONSTITUTION:When supply voltage rises up to a value such as approximately 90% value on the closing of a power supply, supply voltage is detected by a supply voltage detection circuit 4, and a switch circuit 3 is turned OFF. Consequently, input voltage 8 from an automatic power control circuit is applied to an input terminal 9 for a DC driving circuit 2, but the voltage of the input terminal 9 is applied gradually by a resistor R0 5 and a capacitor C0 7, and currents flowing through a semiconductor laser 1 slowly flow. When voltage lowers up to approximately 90% on the OFF of the power supply or on the trouble of some power supply, on the other and, voltage is detected by the supply voltage detection circuit 4, input voltage 8 from the automatic power control circuit is short-circuited with -Vcc when the switch circuit 3 is turned ON, the input voltage of the DC driving circuit 2 is brought to zero potential, and the currents of the semiconductor laser do not flow quickly.

Abstract: PURPOSE:To detect the stop of a clock supplied to a microprocessor by means of a simple circuit which can be constituted of the small number of parts and to prevent the occurrence of a serious fault by initializing a device by means of a clock stop detection signal by the output of a clock stop detection circuit. CONSTITUTION:A clock leading/trailing edge detection circuit 21 in the clock stop detection part 20 detects the leading edge or the trailing edge of a clock signal and a capacitor in a time constant circuit 22 is discharged. When the clock stops, the leading edge or the trailing edge of the clock signal is not detected. Thus, the capacitor in the time constant circuit 22 is continuously charged and the output voltage becomes larger than a prescribed value. A judgement circuit 23 detects it and outputs the clock stop detection signal. A reset circuit 17 transmits a reset signal to the microprocessor 12, an I/O port 13, a driver part 14 and the like by the clock stop detection signal and initializes the device. Thus, a necessary processing when the clock stops can be executed by the simple circuit.

Title: Automobile compressor
Inventor: YANO MIKIO
IPC: F04B49/00
Filed: 1982-09-01
Abstract: PURPOSE:To improve car fuel cost by making a suction control valve, positioned in the refrigerant inlet, freely operable through a negative pressure actuator connected to the negative pressure source, in an engine driven refrigerant compressor. CONSTITUTION:When the number of revolution, i.e., the engine load, is small, the negative pressure in the intake manifold is large, and bellows 21 is constricted against a spring 22, widely opening the inlet 11 of refrigerant compressors 8 and 9, to carry out smooth circulation of refrigerant. As the engine load increases, the negative pressure approaches the atmospheric pressure and a suction control valve 20 starts to close the inlet 11, restricting the circulating quantity of refrigerant and, therefore, suppressing the increase in the load of the refrigerant compressor, i.e., the engine load. Thus, the work for unnecessary circulation of refrigerant is excluded, improving the car fuel cost, while the acceleration capacity is not failed when the cooler is in used. And, being continuous controlling, the riding comfortableness is not affected.
