Title: Movable coil control rod drive device
Inventor: KANAZAWA TAKASHI
IPC: G21C7/14
Filed: 1987-12-23
Abstract: PURPOSE:To obtain a drive device of short scram time and large cushioning effect by preparing freely ascendable check plate in a lower pipe plug while forming the lower end of a drive shaft in hollow cylindrical shape. CONSTITUTION:A check plate 23 having buoyancy in a lower pipe plug 22 at which a flange 22a is prepared on the upper end of a drive shaft 6 is sealed freely ascendably while the lower end thereof is formed in hollow cylindrical shape. The diameter of the check plate 23 is made a little larger than the outer diameter of a hollow cylindrical part 20, and the lower end opening part of the hollow cylindrical part 20 is closed. Since the coolant excluded by the drive shaft 6 rapidly descending at the time of scram is flowed in the drive shaft 6 from a center hole 21 of the hollow cylindrical part 20 till the coolant reaches a lower pipe plug 22 passing through a center hole 18 of the drive shaft 6 upward thereof, resistance is made small and the time necessary for descent is short, scram time can be shortened. On the other hand, when the lower end of the drive shaft 6 reaches the lower pipe plug 22, the end of the hollow cylindrical part 20 touches the upper face of the check plate 23 and the opening part is plugged, the drive shaft 6 receives resistance by the coolant and large cushioning force is produced.

Title: Fiber optic plate
Inventor: SUGAWARA TAKEO
IPC: G02B6/42
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a fiber optic plate which outputs bright rugged images, is easily mountable to a photodetector and is compact even after mounting. SOLUTION: This fiber optic plate 1 has an input end face 4 comprising surfaces 21 and 22 inclined at a slant angle α at which the disturbance light from the inside of the air is removable and, therefore, the fiber optic plate is capable of outputting the rugged images having the high contrast like heretofore. Since the plate has the output end face 4 perpendicular to the axial line of a unit fiber, the rugged images are eventually made incident substantially perpendicularly on the input surface of the photodetector when the output end face 4 is butted and fixed against and to the input surface of the photodetector. The bright rugged images are thus obtd. Further, since this fiber optic plate has the shape that the plate extends in a perpendicular direction from the output end face 4, the fiber optic plate is relatively easily mountable at the photodetector with the high accuracy.

Title: Temperature detecting circuit
Inventor: UCHIDA MASATOSHI
IPC: H05B3/00
Filed: 1988-12-22
Abstract: PURPOSE:To prevent the application of a DC component to a sensor wire with use of a single power supply by connecting a pair of clamp diodes set adverse to each other in parallel between an inverted input terminal and a non-inverted input terminal of an operational amplifier. CONSTITUTION:A pair of clamp diodes D8 and D9 set adverse to each other are connected in parallel between an inverted input terminal and a non-inverted input terminal of an operational amplifier OP1. Therefore a current flowed to the inverted input terminal of the OP1 from a smoothed capacitor via a 2nd resistance R24, for example, is led via the diode D8 or D9. As a result, the voltage level of the inverted input terminal is set less than the forward voltage of the diode. Then the DC component applied to a sensor wire SNW can be substantially neglected. Thus it is possible to prevent the application of the DC component to the wire SNW with use of a single power supply and to simplify the constitution of a power supply circuit.

Filed: 1989-12-18
Abstract: PURPOSE:To automatically count the correct number of bodies by counting the body by increasing a counter every time a scanning line encounters with a part decided to be 'included' by raster-scanning the picture of a calculated result, and in addition, by an arithmetic means to clear that body. CONSTITUTION:The body is extracted from the picture by binarizing processing, namely, the picture of the body 1 and a background are binarized by black and white respectively, and next, in respect of each picture A, arithmetic operation to make '1' when the whole circuit B of minimum diameter centering around that point is included in the body, and make '0' in other cases is executed. As the result, a black circle is displayed at the position of the body, and next, scanning is executed, and when the scanning line encounters with the part of '1', the counter is increased, and the inside of a dot line is cleared into 0. An area to be cleared is the circle whose radius is the difference of the maximum value and the minimum value of the radius of the body, and above-mentioned counting and clearing are executed extending over a whole picture, and the number of the bodies is counted. Thus, the two-dimensional body can be counted correctly.

Title: Manufacture of semiconductor laser
Inventor: UESUGI FUMITO
IPC: H01S5/00
Filed: 1989-12-14
Abstract: PURPOSE:To dispense with a thermally treating process which is carried out at a high temperature for a long time so as to obtain an excellent semiconductor laser small in thermal metamorphosis by a method wherein a multi-quantum well layer(MQW layer) is previously doped with impurity of Si in crystal growth and thermally treated at a low temperature to disorder the quantum well structure. CONSTITUTION:A resist 6 on a GaAs contact layer 5 is selectively removed, Be ions are implanted 7 using the resist 6 as a mask to enable Be ions to reach an N-AlGaAs contact layer 2, and a Be implanted region 8 is formed. At this point, the concentration of the implanted Be is made higher than that of Si implanted into an MQW layer 3. The resist 6 is removed, when a heat treatment is carried out, the MQW layer 3 where Be ions are not implanted is disordered by Si to be a layer of AlGaAs averaged in composition, but the MQW layer 3 in the Be implanted region 8 is not disordered. By this setup, a thermal treatment can be executed at a low temperature in a short time, so that a wafer can be protected against thermal metamorphosis and Al and Ga contained in an MQW layer which is to serve as an active layer can be prevented from diffusing mutually, and as a result an oscillation wavelength hardly deviates.

Abstract: PURPOSE:To eliminate loss due to diode recovery current by judging that the switching current from a detecting means went negative and sustaining OFF state of a switching element on non detecting side, during an interval when the switching current is negative, through a switching means. CONSTITUTION:Upon occurrence of such mode as frequency < inherent frequency, due to transient fluctuation of a load L0, drain currents ID1, ID2 flow through switching elements Q1, Q2. A recovery current is produced when negative current is interrupted, and when a current flows through the diode D2 to produce a negative voltage drop, a comparator COMP is operated and the output of the comparator COMP is held at H level up to the end of current flow through the diode D2. A switching element S is opened during that interval thus disabling the switching element Q1.

Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an air cell having high capacity. SOLUTION: Disclosed herein is an air cell having an improved positive electrode catalyst layer. The application amount of polyvinyl alcohol serving to adhere the positive electrode catalyst layer 6 to the separator 7 is 5-30 g/m2 for a unit area of the positive electrode catalyst layer. The application of the polyvinyl alcohol is carried out before press-adhering a water repellent layer 8 on the opposed side of the positive electrode layer. Thus, bubbles of the polyvinyl alcohol is prevented from being generated, thereby increasing adhesion of the separator. As a result, increase in internal resistance and reduction in available discharging can be prevented, thereby increasing the capacity.
