Title: Method for measuring interval between fuel pellet and cover pipe within fuel element
Inventor: IMAMURA MITSUTAKA
IPC: G01B17/00
Filed: 1988-02-04
Abstract: PURPOSE:To rapidly perform measurement with good accuracy without applying compressive deformation to a nuclear fuel element to a large extent, by a method wherein the gas injected in the nuclear fuel element is liquefied or solidified by cooling and an ultrasonic pulse is emitted into the nuclear fuel element to measure the reciprocating time of said pulse in the nuclear fuel element. CONSTITUTION:A nuclear fuel element 7 being an object to be measured is constituted by laminating fuel pellets 9 within a cover pipe 8 and providing a plenum part provided with compression spring above said pellets. Gas capable of being liquefied or solidified by cooling is injected in the plenum part by a gas injection device 6 and subsequently over-cooled by a fuel element cooler 1 until liquefied or solidified. Hereupon, the ultrasonic pulse generated by an ultrasonic pulse transmitter 2 is transmitted into the element 7. Subsequently, the ultrasonic pulse reciprocating in the element 7 is received by an ultrasonic wave receiver 4. This reciprocating time is measured to make it possible to measure the interval between each of the pellets 9 in the pipe 8 and the pipe 8 of the used element 7 without damaging the pipe 8.

Title: Numbering method of semiconductor wafer
Inventor: MATSUMOTO TAKASHI
IPC: H01L21/02
Filed: 1979-02-28
Abstract: PURPOSE: To number a semiconductor wafer with ease and without any effect upon it by numbering through injected radioactive substance into a selected and specified region at the circumference of a semiconductor wafer.  
     CONSTITUTION: A semiconductor wafer 2 to be numbered is placed on the stage 1 and radioactive substance such as  241 Am etc. is implanted by a ion implantating device 3. In this process when  241 Am is implanted for example with strength of 200keV, it gets to a depth of approximately 30Å into the Si wafer but it does not give any effect on the wafer and on the semiconductor device formed there. Thus radioactive substance is implanted selectively into the specified region a1Wa8 of the wafer 2. And by radioactive substance being implanted only into the hatched regions a5, a8 for example, number information 00001001 that is number 9 is given.

Abstract: PURPOSE:To rationalize the area measurement of a reproduced picture and to improve the precision of good/bad discrimination of an object by automatically adjusting the binarization level of a binarizing circuit in accordance with the reduction of illuminance of a light source with which the object is irradiated. CONSTITUTION:A video camera 1, a binarizing circuit 2, an area measuring circuit 3, an arithmetic processing part (CPU) 4, a storage part (memory) 5, and a D/A circuit 6 are provided.

Consequently, the binarization level is automatically adjusted in accordance with the variance of the level of the binarized signal 2a though this level is varied by the degradation of the light source with which the object is irradiated, disturbance, or the like. Thus, the area is accurately measured to discriminate whether a product is good or not with a high precision.

Title: Magnetic recording medium
Inventor: KAZAHAYA TOMIO
IPC: G11B5/66
Filed: 1988-02-05
Abstract: PURPOSE:To enhance the adhesiveness of a diamond-like carbon film as a top coat film to a thin magnetic metallic film and to prevent film exfoliation and cracking by adopting the constitution in which the content of the binding hydrogen in the diamond-like carbon film is decreased toward the surface side. CONSTITUTION:This recording medium is constituted by forming the thin magnetic metallic film 2 consisting of a Co film or the like on a base 1 consisting of an Al alloy formed with an Ni-P plating layer and forming the diamond-like carbon film 3 as the top coat film on the layer 2. The content of the binding hydrogen in the film 3 is decreased stepwise or continuously from the film 2 side toward the surface side. For example, plural layers of the thin film layers 3-1-3-3 which are different in the content of the hydrogen are formed by stepwise changing the reaction conditions for a gaseous carbon source (e.g.: methane) or gaseous carbon source and carrier gas (e.g.: hydrogen) in the case of forming the film 3 by an RF plasma DVD method. The thin films in which the content of the hydrogen decreases continuously are otherwise formed by continuously changing the reaction conditions.

Title: Controller for switching steam source of steam header
Inventor: HATSUMI HIROSHI
IPC: F01K13/02
Filed: 1989-02-03
Abstract: PURPOSE:To switch steam sources promptly while restraining the pressure fluctuation of a steam header by controlling the speed of opening movement of a switching valve to that speed at which it is possible to restrain the pressure fluctuation of the steam header, according to the rate of opening of a pressure control valve located downstream of the switching valve. CONSTITUTION:While steam sources A, B are switched, either a motor-driven switching valve 3A or 3B is opened and the other valves are closed. In accordance with the rate of opening of a pressure control valve 4A (or 4B) located downstream of the switching valve, the speed of opening movement of the switching valve 3A (or 3B) to be opened is controlled by opening movement speed control means 21A (or 21B) via a pressure controller 6A, 6B to that speed at which it is possible to restrain the pressure fluctuation of a steam header 1. While the pressure fluctuation of the steam header is restrained, the steam sources can thus be switched promptly.

Title: Power antenna output circuit for car audio
Inventor: KIZUKI DAISUKE
IPC: H02H3/08
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a power antenna output circuit for car audio which protects an output transistor from an overcurrent caused by the short circuit, etc., of an output load. SOLUTION: An output transistor Q1 is protected from an overcurrent caused by the short circuit, etc., of a power antenna output OUT by increasing a load (output current i1), dropping a potential V1, turning on a transistor Q3, and turning off the transistor Q1. When the transistor Q1 is protected, the value of the current i1 is arbitrarily decided from the turning-on voltage of the transistor Q3 and the value of a resistor R0. In addition, the potential V2 of the power antenna output OUT when the transistor Q1 is turned off is decided from the values of resistors R4 and R7.  (In this case, the values of resistors R4, R2, and R3 are set so that the transistor Q3 can be maintained in a turned-on state.) When the state returns to a normal state and the load is reduced (the value of the resistor R increases to a larger value from a smaller value) (when the current i1 becomes smaller and the potential V2 becomes higher), a protective circuit operates only when an excessive current flows by limiting a current iB, turning off the transistor Q3, turning on the transistor Q1, and making the current i1 to flow to the resistor R7 through a resistor R0.
