Patent JP-H0328794-A (JP)
Title: Fuel assembly for boiling water reactor and its water pipe for cooling water flow
Inventor: TSUDA KATSUHIRO
IPC: G21C3/326
Filed: 1989-06-27
Abstract: PURPOSE:To make a pressure drop small by nearly equalizing overall axial length to the fuel effective length of a fuel rod and making the tube plate thickness in a lower area having its border at a height position which is about 1/3 - 2/3 time the overall axial length larger than the tube plate thickness in an upper area. CONSTITUTION:A short-sized W channel has maximum deformation due to creeping at the position P of about 1/3 height from the short-sized channel. This results from that the acceleration factor of fast neutrons affects the creep deformation fo the short-sized channel in addition to the inside/outside pressure difference. For the purpose, the plate thickness (d) in the upper area U of the short-sized W channel is so determined that the creep deformation quantity at the part is nearly equal to or less than the maximum deformation quantity. For example, when the plate thickness (d) in the lower area U is 0.7mm, the plate thickness (d) in the lower area D is 1.5mm. Consequently, the pressure drop in an in-channel area to a two-phase flow is reduced and channel stability is improved.

Title: Rear door switch circuit
Inventor: NAKAJIMA SACHIHIRO
IPC: B60J5/10
Filed: 1985-07-25
Abstract: PURPOSE:To stop the application of voltage and prevent an electrical shock and the occurrence of a short circuit when a connector on the body side is disconnected from that on a door side, by applying voltage to said door side connector through a relay circuit and actuating the relay circuit on currents running through both of said connectors. CONSTITUTION:When a switch 4 is operated with a door side connector 6 coupled to a body side connector 5, an electric current runs from a battery 1 to the coil 8a of a relay 8 and each terminal 5c, 6c, 6a and 5a of both connectors 5 and 6, thereby closing each contact point 8b and 8c. As a result, a hot-wire defogger 9 is applied with voltage from the battery 1 and an indicator 7 is lit on. On the other hand, when both of said connectors 5 and 6 are disconnected from each other, terminals 5c and 6c, and 5a and 6a are disconnected from each other and no driving current runs to the coil 8a, even if the switch 4 is turned on, thereby keeping each contact point 8b and 8c open and the terminal 5b free from the application of voltage.

Abstract: PURPOSE:To improve the efficiency of the execution arithmetic of a digital signal processing means by providing an external storage control means with a storage buffer means and an external storage control means which indicates writing/reading operation when there is a request to write or read data in and out of the external storage means. CONSTITUTION:The external storage control means 9 confirms the end of data writing/reading operation between the digital signal processing means 3 for processing such as the actual arithmetic of a signal and the storage buffer means 10 which writes and reads the arithmetic result of the digital signal processing means 3 in and out of an external storage means described below, and instructs the external storage control means 8 to perform the writing/ reading operation of the storage buffer means 10 and external storage means 7 when there is a request to write and read data in and out of the external storage means 7, thereby controlling the operation states at all times. Consequently, a decrease in the efficiency of the execution arithmetic of the signal processing based upon the frequency of data access to the external storage means 7 is reduced.

Title: Internal pump
Inventor: OKADA AKIHISA
IPC: F04D13/06
Filed: 1980-11-21
Abstract: PURPOSE: To enable to supply a sufficient amount of cooling water into a motor case, by providing a back-flow preventing means at a portion of a fluid passage in the motor case of an internal pump used for circulating nuclear reactor cooling medium.  
     CONSTITUTION: When a shaft 4 is set into rotation and cooling water is supplied forcedly by an auxiliary impeller 3, water tends to flow reversely from a water chamber A to a water chamber B but it is prevented by a back-flow preventing means 19. At the time when operation of a pump is stopped, temperature of the pump is raised by the heat transmitted from a pressure vessel of a nuclear reactor, with the temperature rise being greater toward above, and water is made to flow from the water chamber B to water chamber A by way of natural convection, so that the back-flow preventing means 19 is not operated. Therefore, a sufficient amount of cooling water flows as shown by dotted lines in the drawing by way of natural convection, by-passing small gaps in bearings, so that heat transmitted from the pressure vessel of the nuclear reactor can be absorbed by the cooling water.

Filed: 1986-07-11
Abstract: PURPOSE:To detect the toner concentration of a developer always with high accuracy by forming a transparent window for a toner concentration detector on a developer carrying thickness regulating member and forming a smooth curved surface connected to the ceiling surface of a developer container on the upper part of the regulating member. CONSTITUTION:Excess developer is raised along the inwall surface of the blade developer carrying thickness regulating member 109 in the arrow P2 direction, after scrapping the surface of the transparent window 109a so as to clean the surface of the window 109a, guided by the curved surface 109b of the blade 109, inverted in the direction along the ceiling surface 104a of the developer container 104, and then dropped in the arrow P3 direction. The curved surface 109b acts so as to increase the flow rate of the developer slided on the surface of the window 109a and interrupt the adhesion of the developer to the window 109a. Infrared rays or the like are radiated from the toner concentration detector 111 through the window 109a, the reflected light from the developer is converted into an electric signal and a developer toner concentration detecting signal is generated. Consequently, the toner concentration can be accurately detected and the toner concentration in the developer can be controlled always at a fixed value.

Title: Automatic gain control circuit
Inventor: TAKENAKA SHINYA
IPC: G06K9/20
Filed: 1990-06-21
Abstract: PURPOSE:To satisfactorily read the symbols after the regular reflected light is made incident on a detecting element by resetting the peak holding level of a peak holding circuit when the peak holding level exceeds the prescribed reference value. CONSTITUTION:The output signal of a variable gain amplifier 10 is applied to a peak holding circuit 20, and the output signal of the circuit 20 is inputted to the circuit 10 as a control signal which controls the gain of the circuit 10. A reset circuit 30 is connected to the circuit 20 to reset the peak holding level of the circuit 20. Thus it is possible to evade such a case where the gain of the amplifier 10 is kept extremely reduced even if the output signals of a detecting element are temporarily increased due to the light reflected regularly from the symbol surface. As a result, a normal reading state is quickly reset even though the light reflected regularly from the symbol surface is received by the detecting element.

Filed: 1995-06-07
Abstract: PURPOSE: To reduce the reflection of a fluorescent lamp, etc., to eliminate flicker on a display surface and to easily watch an image by specified the average projection interval of surface roughness on a coordinate input surface for handwriting input device. CONSTITUTION: When inputting a character or a graphic while using this handwriting input device, a handwriting input pen 8 is taken with a hand, a tip 9 of the pen is abutted to the prescribed position of a coordinate input surface 10 as the upper surface of an upside insulated substrate 5, and the prescribed character or graphic is written while abutting the tip 9 of the pen to the coordinate input surface 10. Here, the tip 9 of the pen and downside and upside electrode parts 4 and 5 are capacitance-coupled and a coordinate signal is detected. This coordinate signal is inputted to the arithmetic circuit of a computer or the like. In this case, it is necessary for the coordinate input surface 10 to set the average projection interval of surface roughness from 0 to 100μm.  When this average projection interval is 0μm, light from the outside such as the fluorescent lamp is reflected and the display of the screen is hardly watched because it is dazzling. When the average projection interval exceeds 100μm, the effect of flicker prevention can not be provided and the displayed image is hardly watched.
