Title: Digital-analog converter
Inventor: IKEDA OSAMU
IPC: H03M1/80
Filed: 1982-04-14
Abstract: PURPOSE:To obtain a smooth analog signal output which varies with the same step width, by using a digital signal of the highest bit to have a switch between the application of the 1st decoding part and the application of the 1st and 2nd decoding parts. CONSTITUTION:The signal of the highest bit (MSB)b3 applied to an input terminal 10 is inverted by an inverter 28 to be applied to NOR gates 14-16 and NAND gates 17-19 as well as to an MOS transistor 20 via an inverter 29. A ratio of 1:2:4 is secured for channel widths among MOSTR26, 25 and 24 as well as MOSTR23, 22 and 21 respectively. Then an internal impedance ratio is set at 4:2:1 for those MOSTRs to ensure the weighting.

IPC: B63B35/44
Filed: 1989-03-17
Abstract: PURPOSE:To obtain a floating type vibrationproof structure which possesses the vibrationproof effect for the vibration in the vertical direction by installing an air tank at the boundary part between the lower part of the earthquakeproof structure and fluid. CONSTITUTION:An air tank 6 is installed by forming a recessed place on the bottom surface of a structure 2. Then, the part which directly receives the fluid pressure 10 by the vibration 5 in the vertical direction is only the part P shown by the dotted line, and the force acting onto the structure 2 reduces. Therefore, even in the pressure variation is generated by the vibration 11 of the liquid level which is caused by the vibration 5 in the vertical direction, the air tank 6 operates as a kind of pneumatic spring, and the buffering effect is generated for the structure 2, and the earthquake force is reduced. Further, since, for the vibration 4 in the horizontal direction, the vibration 4 in the horizontal direction is insulated by the fluid 3 similarly in the conventional structure, the earthquake force is hardly transmitted to the structure 2.

Abstract: PROBLEM TO BE SOLVED: To prevent reactivity of fuel which is previously highly concentrated from locally suddenly rising, and prevent control rods from being poorly inserted, due to sudden increase of moderator flow by bending deformation caused by vibration of earthquake or the like, concerning nuclear fuel assembly to be charged in a boiling water reactor. SOLUTION: Adjoining nuclear fuel assembly (a1 ), (a2 ) are standingly mounted in the upper grid plate 4 of a reactor core 1 by elastic contact of the leaf springs 17a, 17b of the channel fasteners 17 of respective channel boxes 16. The degree of bending of the nuclear assembly (a2 ) on the channel fastener 17 side by earthquake is restrained by wholly pressure fitting the channel box 16 to the upper grid plate 4 by means of the lower adjoining elastically contact part 19c of the leaf springs 17a, 17b, and compared with this, the degree of bending of the nuclear fuel assembly (a1 ) on the upper grid plate 4 side is not so restrained. Hereby, width spreading of a narrow no control rod side cooling material flow passage G2 is restrained, and sudden rise of reactivity of the highly concentrated fuel and defective insert of the control rods are restrained.

Title: Solid-state electron emitting device
Inventor: TSUKAMOTO TAKEO
IPC: H01J1/30
Filed: 1990-03-16
Abstract: PURPOSE:To improve electron emitting efficiency by forming a heterojunction with different band gaps in a base region and injecting electrons to the base region from an emitter region and at the same time applying reverse bias to the base region and a collector region. CONSTITUTION:When a reverse bias is applied between a base and an emitter with an electric power source 10, electrons in the emitter layer 2 are injected into a first base region 3. The electrons cross a heterojunction between a second base region 4 and the region 3 while running on the base. At that time, the discontinuity ALPHAEC of the bands of the heterojunction is about 0.3eV and owing to the energy level difference, the electrons injected into the base become thermal electrons. The thermal electrons are accelerated further by the electric field between the base 4 and the collector 5 and spring out to vacuum. The collector layer 5 is thinned and Cs, etc., is deposited on the surface so as to make the work function of the surface small and increase the electron emitting amount.
