Title: Shield plug for fast neutron reactor
Inventor: HASHIGUCHI ISAO
IPC: G21C13/06
Filed: 1978-05-19
Abstract: PURPOSE: To improve a performance of thermal insulation with an infiltration prevented of the sodium vapor, by means of hanging a thermally insulated part in the cylindrical unit, protrusively provided below a rotary plug, to provide a ring-shape plate through an adiabatic material.  
     CONSTITUTION: A cylindrical unit 15 is protrusively provided below a rotary plug, and in its interior is hung a layer-built thermally insulated part 20. To the thermally insulated part 20, are tightened a spacer 22 and a shield disc 23 made of metal by a nut 24, and to the disc 23 is connected a ring-shape disc 26 through a thermally insulating washer 25. With peripheral surfaces of the disc 26 so made as to be contacted to inner surfaces of the cylindrical unit 15 and an infiltration of sodium vapor prevented, a deterioration of the thermal insulation performance due to the sodium can be prevented. And no clearance between the cylindrical unit 15 and the layer- built thermally insulated part 20 eliminates a production of convection, capable of improving the thermal insulation.

Title: Superconductive device
Inventor: TANABE KEIICHI
IPC: H01L39/22
Filed: 1986-03-17
Abstract: PURPOSE:To reduce leakage currents between a base and a collector by covering the periphery of a base superconductor and adding a gate electrode controlling the curve of the energy band of a compound semiconductor surface layer just under the base superconductor. CONSTITUTION:An MIS type gate electrode 114 is formed around a base 111, and bias voltage is applied to the gate electrode 114. Consequently, the curve of the potential of an energy band in the vicinity of the surface of a compound semiconductor layer 110 just under the base 111 is changed, and a current path having high conductivity is interrupted by bringing a superconducting device to a depletion state, thus preventing leakage currents between the base and a collector. Leakage currents can be inhibited to quasiparticle currents or less positively by gate voltage having proper magnitude when there are a large number of interface levels in order to change the storage state of carriers into the depletion state.

IPC: B41J2/355
Filed: 1995-03-17
Abstract: PURPOSE: To obtain a cooling time for preventing a break of a heat-generating element thereby to effectively protect the heat-generating element, by generating a power feed prohibition timing signal with an approximately fixed ratio to a printing cycle, observing a power feed timing signal by the power feed prohibition timing signal, and stopping the supply of power when the power is being supplied. CONSTITUTION: An optical sensor is set at each end of a guide shaft to detect each end position of a head carriage 3. A transmission-type optical sensor is disposed adjacently to a slit rotary plate fitted at a projecting part at a rear end of an output shaft 81 of a D.C. motor 8. A rise signal of a detection signal of the transmission-type optical sensor is input to a driving/controlling circuit as a power feed synchronous signal. A power feed width is determined at the driving/controlling circuit based on detection results of surrounding temperatures and a supplied voltage to achieve proper generation of colors, and a power feed timing signal is output. A power feed time is determined from an AND of the power feed timing signal and a power feed prohibition timing signal. A power feed pulse signal is consequently output.

Title: Power transmission device by timing belt
Inventor: YAMAGUCHI TOSHIHIRO
IPC: F16H7/02
Filed: 1983-04-06
Abstract: PURPOSE:To prevent timing belt teeth from being damaged and worn by setting the pitch of the timing belt teeth eithe larger or smaller relative to the pitch of teeth of a belt wheel. CONSTITUTION:In a case where a timing belt 2 is driven by a belt drive wheel 1, if the pitch of teeth of the timing belt 2 are elastically displaced smaller than that of belt wheels 1, 3, 4, load will be larger on the trailing side of the teeth engagement than the leading side, resulting in wear or damage in certain teeth of the timing belt 2. A similar situation occurs when the pitch of the timing belt teeth are elastically displaced to become larger than that of the belt wheel teeth. Therefore, in order for the load on each tooth in an area where the timing belt engages the belt wheel to be uniform, the pitches of their teeth are changed relatively in advance to lessen the load on the teeth.

IPC: H02H7/08
Filed: 1978-05-18
Abstract: PURPOSE: To detect a trouble of the primary and secondary sides of an induction motor, by detecting only secondary current of the motor and processing the detected current.  
     CONSTITUTION: Two optional phase (U2, V2) currents of the secondary side of the induction motor are detected by secondary current probes 4, 5. The detected current signals 4', 5' are converted into envelope forms 6c', 6d' through detection circuits 6a, 6b and envelope circuits 6c, 6d. The envelope forms are applied to an imbalance ratio calculation circuit 6e consisting of an addition circuit, a differential circuit and a division circuits to pick out an imbalance ratio 6e', i.e., (IU a -IV a ) Δ/(IU a + IV a ). One optional detected current signal 5', for example, is applied to a band-pass  filter 64 to pick out a 2f(1-s) component. This component is converted into a DC  signal by an AC-DC converter 6g to obtain a 2f(1-s) level 6g'. The levels of the  output signals 6e', 6g' are displayed by an indicator 7.

Subsequently, when an organic solvent is dropped down uniformly by a prescribed quantity to an organic solvent holding member 40 on an organic solvent holding base 39, and the base 39 is put into the vessel 41, an organic solvent vapor is generated. Its vapor passes through an opening part 39b of the base 39, becomes full in the vicinity of a copy 38 on the plate 37, and starts to dissolve the toner on a transparent copy. After a prescribed time elapses, the placing plate is drawn out, the copy 38 is taken out, and the toner layer side is dried. In this way, the toner is color developed without generating an uneven part.

Abstract: PURPOSE: To reduce an opening area of a valve where flowing sound of water flowing in a cock is generated and to improve stillness by increasing a sectional area of a water channel on the downstream side immediately after the valve interposed in the water channel. CONSTITUTION: A water channel 12 is formed inside of a cock 11 for hot water flow rate control used for a heating route of a vehicle, etc., a hose insertion port part 13 is provided on an upstream end, a heater core connection port 14 is provided on a downstream end, and a valve 15 is interposed in the middle of the water channel 12.

Title: Heat accumulating device
Inventor: YAMAGUCHI KOICHI
IPC: F28D20/02
Filed: 1988-03-16
Abstract: PURPOSE:To make a device compact and to reliably prevent a latent heat accumulating material from being brought into an overcooling state without consuming surplus energy, by a method wherein a part containing a connection part between a branch pipe and a container is formed by a material having thermal conductivity lower than that of the container, and the other part is formed by a material thermal conductivity higher than that of the container. CONSTITUTION:With a switch 6 turned ON, a heater 5 is charged with a current, a metallic container 2 is heated, and heat is accumulated in a heat accumulating material 4. In this case, the heat of the heater 5 is transferred to a branch pipe 8 through the container 2, but since the root part of the branch pipe 8 is a low thermal conductivity material part 9, a quantity of heat transferred to the branch pipe 8 is extremely low. A high thermal conductivity material part 10 is located to the forward part of the low thermal conductivity material part 9, and besides since a radiation fin 11 is mounted, heat possessed by a heat accumulating material 4 in the branch pipe 8 is rapidly dissipated in the surrounding air. As noted above, an amount of heat flowing out to the surrounding air can be set to a high value as an out of heat coming in the branch pipe 8 is suppressed. When, after completion of heat accumulation, the heat accumulating material 4 is cooled to take out heat, the heat accumulating material 4 can be reliably prevented from being brought into an overcooling state.

Abstract: PROBLEM TO BE SOLVED: To precisely diagnose an electric apparatus by excluding the influence due to a wind velocity, by a method wherein the wind velocity near a temperature measuring part at the electric apparatus is measured and various set values of a thermal image in a thermograph are set on the basis of the wind velocity.

As a result, the electric apparatus can be diagnosed precisely by excluding an influence due to the wind velocity.
