Title: Liquid-metal cooled fast reactor
Inventor: KANBE MITSURU
IPC: G21C1/02
Filed: 1989-02-07
Abstract: PURPOSE:To eliminate the need for a control rod drive mechanism and fuel exchanging device by fixing an annular diametral reflector into a coolant and providing two upper and lower axial reflectors. CONSTITUTION:An output unit 2 is inserted to the diametral reflector 4 positioned at the bottom end of the nuclear reactor in order to start this nuclear reactor. Then, the disposition of the diametral reflector 4 and a reactor core 8 change gradually and the core 8 comes to be enclosed by the two axial reflectors 9a, 9b and the diametral reflector 4 so that the output of this reactor attains critical. Further, the output of the reactor increases gradually as the axial reflector 9a positioned at the bottom end of the output unit 2 is inserted deep into the diametral reflector 4. The output of the reactor is maximized when the core 8 is positioned at the center of the diametral reflector 4. The need for the control rod drive mechanism and fuel exchanging device which are heretofore required for the conventional liquid-metal cooled fast reactor is eliminated in such a manner.

Title: Exhaust gas treatment device of internal combustion engine
Inventor: SEKIYA YOSHIKI
IPC: F01N9/00
Filed: 1990-02-08
Abstract: PURPOSE:To charge a battery preliminary to meet a current-carring quantity during regeneration by increasing idling speed immediately before the regenera tion of an exhaust gas trap and increasing the speed more during the regenera tion. CONSTITUTION:In a negative pressure actuator 16, the negative pressure to be applied can be controlled by solenoids SOL4, SOL5, and an idling speed can be increased by operating the control lever 15 of a fuel injection pump 10. A control unit 20 turns on the solenoid SOL4, and the idling speed is increased to the first setting point before the regenerating operation of an exhaust gas trap 4 for preliminary battery charging. At the time of the regeneration, the solenoid SOL5 is also turned on to increase the idling speed to the second setting point higher than the first setting point. It is thus possible to prevent battery discharging due to sudden increase in the current-carrying quantity to an electric heater 11 and so on during the regeneration and to compensate a stable regeneration action.

Title: Optical switch
Inventor: TOMIYAMA TADAO
IPC: H01H35/00
Filed: 1989-02-08
Abstract: PURPOSE:To reduce the number of parts and improve a dynamic range by installing an optical fiber holding guide which takes a light projecting side optical fiber and a light receiving side optical fiber about in a covering case, and an actuator and a douser which opens and closes an optical path by means of an actuator. CONSTITUTION:An optical switch opens and closes an optical path by a douser 7 which makes frequent appearances in a gap between a light projection side optical fiber 3 and a light receiving side optical fiber 4 by means of an actuator 5. An optical fiber holding guide 5 is installed in a covering case 1 to position and hold the optical fibers 3, 4 of a light projection side and a light receiving side at a fixed position, and both end faces of the light projection side optical fiber 3 and the light receiving side optical fiber 4 are directly opposed to each other interposing a very narrow optical path gap where the douser 7 makes frequent appearances. All of such optical elements as a reflecting mirror, a prism, etc., therefore, become unnecessary between the light projection side optical fiber 3 and the light receiving side optical fiber 4, and also, it is possible to reduce a loss of a quantity of transmitting light by shortening the length of an optical path between optical fibers. Thereby, it is possible to greatly improve an optical transmissivity between the light projection side optical fiber 3 and the light receiving side optical fiber 4, or dynamic range and also reduce the number of parts and the cost.

Title: Video signal record reproducing device
Inventor: HIROSE KOUICHI
IPC: H04N9/86
Filed: 1983-02-25
Abstract: PURPOSE:To enable stable discrimination of color difference signals and realization of faithful reproduction of waveform by performing switching of color difference signal in back porch period during horizontal blanking period. CONSTITUTION:Line switch pulse is generated in a line switch pulse generating circuit 5 from a synchronizing signal (a) obtained in a synchronizing separator circuit 4, and the color difference signal is switched alternately every 1H to obtain line sequential color difference signal. When FM modulating the color difference signal, oscillating frequency is made different every 1H taking line discrimination in reproduction into consideration. For stable clamping, switching point of the line switch must be set at a position delayed from the position of synchronizing signal. However, if the delay is excessive, the switching point appears on the picture. Former waveform is reproduced correctly from the beginning of blanking to the switching point when the switching point is set during back porch period.
