Title: Infrared detector
Inventor: KAJIWARA NOBUYUKI
IPC: H01L31/10
Filed: 1989-06-28
Abstract: PURPOSE:To obtain an infrared detector high in sensitivity to infrared rays of long wavelength and small in dark current by a method wherein the infrared detector is provided with a photodiode whose P-N junction region with a prescribed pattern is formed on a semiconductor substrate, where the substrate is continuously decreased in minority carrier density starting from the P-N junction along the depthwise direction of the substrate. CONSTITUTION:An infrared detector is provided with a photodiode whose P-N junction region 11A with a prescribed pattern is formed on a semiconductor substrate 11 by introducing impurity atoms whose conductivity type is opposite to that of the substrate 11 into the semiconductor substrate 11, where the substrate 11 is continuously decreased in minority carrier density starting from the P-N junction 11A along the depthwise direction of the substrate. For instance, the P-type Hg1-XCdXTe substrate 11 so structured as to increase in carrier density 11A along the depthwise direction is employed, where the minority carrier concentration of the substrate 11 decreases continuously starting from the P-N junction 11A along the depthwise direction form 10<10>/cm<2> through 10<8>/cm<2>. By this setup, the electron density decreases in rate of change at the end of a P-N junction when a reverse bias is applied, and a detector small in dark current can be obtained.

Title: Short discharge pipe of pump incorporated with cooler
Inventor: KOMATSU TAKEHIKO
IPC: F28D7/00
Filed: 1979-12-26
Abstract: PURPOSE: To prevent clogging of a river water flow passage to facilitate thr cleaning thereof by constituting the short discharge pipe of the pump incorporated with a cooler in which the river water is used as a coolant by two pipes the inner pipe of which has a corrugated cross section and flowing a fluid to be cooled between the inner and outer pipes and the river water through the inner pipe.  
     CONSTITUTION: The pump discharge short pipe is double layered, i.e. an inner pipe 8 and an outer pipe 7; the inner pipe 8 has a linear shape longitudinally, while its sectional shape has a corrugation wherein its trough is widened axially. With such a construction, when the fluid to be cooled is fed into a passage 9 formed between the inner and outer pipes 8 and 7, it flows through the passage 9 meandering in the axial direction. In this while, the fluid is cooled by the river water and then discharged out of an outlet port 11. This configuration of the inner pipe 8 is very advantageous in preventing the dust contained in the river water from clogging the inner pipe 8 and in facilitating the removal of grease attached to the inner wall of the pipe. Accordingly, it becomes unnecessary to provide an automatic strainer, water take-in and supply pumps, which results in the minimization of the system in size.

Title: Safety device control device for boiler during spontaneous power failure
Inventor: KAYAHARA TOSHIHIRO
IPC: F23N5/24
Filed: 1992-06-02
Abstract: PURPOSE:To make it possible to secure safety and reopen the operation in automatic mode when spontaneous power failure occurs by forcibly halting combustion if spontaneous power supply is detected and scavenging a combustion chamber after the spontaneous power failure is returned and restarting the combustion under the condition that there exists a heating demand signal. CONSTITUTION:A detection section 1B controls a fuel valve VQ or the like based on a control procedure for spontaneous power failure when spontaneous power failure is detected based on a voltage value of a power supply line 3. A heating demand detection switch 2 detects hot water temperature in the upper level in a drum and it is turned on or off according to the detected value. A control section 1 drives a fan FM when a heating demand signal is received, and opens the fuel valve VQ after having pre-purged for a specified time, then drives an igniter IG and transfers the combustion to steady combustion mode after having confirmed the ignition. This construction makes it possible to secure safety and, what is more, to reopen the operation in automatic mode without producing any interlocked state.

Abstract: PURPOSE:To display the tuning state between a frequency received at present and neighboring broadcast frequencies, by counting the intermediate frequency from an intermediate frequency amplifier with a counter, in a radio receiver to know the degree of shift to a normal intermediate frequency. CONSTITUTION:Electromagnetic waves caught on an antenna 11 are selected through resonance at a harmonic tuning circuit 12, transmitted to a mixer 13, mixed with a local oscillation frequency of a local oscillator 14, outputted to an intermediate frequency amplifier 15. The output of the amplifier is fed to a detector 16 and applied to a frequency counter 19, where a frequency is counted and the counted value is loaded to an intermediate frequency range discriminating circuit 20. The circuit 20 discriminated the range of a shift (the shift might be about 455kHz) depending on the degree of the tuning frequency shifted to the frequency of broadcast electromagnetic waves and outputs the result of discrimination to a display control circuit 21. Further, an output of the amplifier 15 is detected of its strength of electric field, at an electric field strength detection circuit 18, and an output of a control circuit 21 applied to a display 22 is controlled by said electric field strength and the discriminated output is displayed when the electric field strength is a prescribed value or over.

Title: Integrated packet communication system
Inventor: ABE MINORU
Filed: 1987-07-08
Abstract: PURPOSE:To transmit different kinds of media efficiently by predetermining the constitution of a frame being a transmission unit of the medium in response to the kind of the media. CONSTITUTION:When a voice packet is transmitted, at first the presence of voice information is sent from an information transmission section 6 to a transmission frame identification setting section 4. The setting section 4 generates a frame identification field FI for voice and sends it to a transmission control section 5 and a frame transmission section 3. Then the section 5 generates only the address for communication party selection and sends the voice information packet via the frame transmission section 3. On the other hand, when a data packet is transmitted, the section 4 generates a data identifier field and sends it to the transmission control section 5 and the section 3. Thus, the section 5 generates the address for communication party selection transmission control information and transmits the data packet via the transmission section 3.
