Patent JP-H03274491-A (JP)
Title: Boiling water nuclear reactor
Inventor: SUZUKI KENICHI
IPC: G21C5/16
Filed: 1990-03-26
Abstract: PURPOSE:To enable prevention of substantial blocking of an inlet part at a lower part of a fuel assembly by foreign objects by providing a prevention net for flowing-in foreign objects at a lower plenum underneath a reactor core part in order to prevent the foreign objects from flowing into the reactor core part. CONSTITUTION:In case that cooling water into which foreign objects are mixed, flows into a nuclear reactor pressure vessel 1 and flows from a lower plenum part 4 to a reactor core part 3, larger objects are captured by a mesh of a metal net 15 for prevention of foreign objects flowing-in and therefore flowing-in of the objects are well prevented. Since an area of the metal net 15 is highly larger compared to an area of an inlet part of a fuel assembly in the reactor core part 3, even if a part of the metal net 15 is blocked by the foreign objects, the cooling water can flow into the reactor core part 3 through the part other than the blocked one and therefore the net 15 is not completely blocked. Also, the fact that a large enough amount of the foreign objects are mixed into the cooling water, is very far from probable. Furthermore, the fact that foreign objects small enough to come through the mesh of the metal net 15 flow into fuel assemblies 2 and block them locally, is rather probable, but fuels do not melt by such a local blocking and there is no possibility for the local blocking to extend to a large scale accident.

Abstract: PURPOSE: To obtain the titled device which can accelerate printing speed by a mechanism wherein a drive gear mechanism is provided with a gear having a tooth lacking portion for temporarily stopping the revolution of type rings, the blank portions of the type rings can be omitted, and a single small-sized motor is used as a drive source.  
     CONSTITUTION: When a drive gear mechanism 23 is operated by means of a pulse motor 25 to start the revolution of a type ring drive gear 35 by means of the main drive gear 37, type rings 22 are rotated. Printing corresponding to one line portion is conducted by instructions from the outside during the time when the type rings 22 make one revolution, and the revolution is temporarily stopped because a tooth lacking portion 41 of the main drive gear 37 is directed at a location of the type ring drive gear 35 when the type rings 22 precisely make one revolution. During that time, a rubber roller drive gear 40 is rotated by means of a tooth lacking gear 38, and paper is fed corresponding to one pitch by means of a rubber roller 29. The outer diameters of the type rings 22 are decreased, and printing speed can be accelerated only by a portion corresponding to the portions.

Title: Processing circuit for video signal of positive polarity synchronizing signal
Inventor: YAMADA HIDEYUKI
IPC: H04N5/16
Filed: 1989-03-27
Abstract: PURPOSE:To realize the sure detection of a frame pulse by superposing a signal varying gradually on an input video signal and generating a period in which the center level of a video signal coincides with the center level at the time of A/D conversion. CONSTITUTION:Before a PLL 8 is locked, a switching circuit 11 is changed over to (a)-side, and the gradually varying signal SV from an oscillation circuit 12 is superposed on the input video signal. Owing to this processing, even if the center level of the input video signal deviates widely from the center level at the time of the A/D conversion, the period in which the center level of the video signal coincides with the center level at the time of the A/D conversion is always generated, and the PLL 8 is locked during this period. When the PLL 8 is locked, the switching circuit 11 is changed over to (b)-side by a switching control signal from the PLL 8. Then, a clamp pulse SCL is outputted from the PLL 8, and the input video signal is clamped at a prescribed clamp level by a clamping circuit 4, and the frame pulse can be detected.

IPC: H01L21/82
Filed: 1986-03-31
Abstract: PURPOSE:To enable the attainment of efficient and stable operations by constructing at least one kind of wirings by means of parallel connection of a plurality of conductor layers. CONSTITUTION:Wirings 2a and 2b and wirings 3a and 3b, as well as lead wirings 7a-7c and 8a-8c, are provided on a semiconductor substrate, and the wirings 3a and 3b are arranged from pads 9a and 9b in such a manner that one part of these wirings is disposed inside a chip while the other part of them is so disposed as to hold buffer circuits 4a-4i between, and that the lead wirings 7a-7c aud 8a-8c are surrounded thereby. Moreover, one part of the wirings 3a-3b extending inside connects the lead wirings 7a-7c and 8a-8c together respectively through through holes 10 so as to supply a circuit element with a power, while the other part of them connects the wirings 2a and 2b disposed in parallel through through holes 10 so as to supply the buffer circuits 4a-4i with a power through connecting portions 5a-5i aud 6a-6i. Accordingly, resistance is made smaller in wiring portions of the buffer circuits 4a-4i than in the case of a single layer by connecting the wirings 2a and 2b and the wirings 3a and 3b together respectively, and therefore it can be avoided to enlarge the width of wirings and consequently to increase an area occupied by wiring elements.

Title: Start system for external storage device
Inventor: FUJII SHOZO
IPC: G06F3/06
Filed: 1990-03-22
Abstract: PURPOSE:To prevent the delay of processing for a preferential request by taking out one non-preferential request from a non-preferential start queue buffer at intervals of a frequency (n) in start request taking-out from a preferential start queue buffer, and starting a large-capacity external storage device. CONSTITUTION:Immediate requests 4 and 6 are successively stored in a preferential start queue buffer 2, and a holding request 5 is stored in a non-preferential start queue buffer 3. A CPU 7 takes out one start request from the buffer 3 at intervals of the frequency (n) in start request taking-out from the buffer 2 to start large-capacity external storage devices 1A and 1B. Thus, the start request of devices 1A and 1B is processed preferentially to the start request due to a holding start factor when being due to an immediate start factor. Consequently, the delay of processing of the immediate request is prevented.

Title: Automatic sound volume adjuster
Inventor: TANIYAMA TAKASHI
IPC: H03G3/32
Filed: 1980-06-03
Abstract: PURPOSE:To prevent the malfunction of an automatic sound volume adjuster at the interruption of broadcast signals, by the constitution that a reception signal voltage is compared with a reference signal voltage and the operation of sound volume adjuster is controlled by turning on and off the gate circuit according to the result of comparison. CONSTITUTION:A DC voltage from an intermediate frequency amplifier 12 is fed to a comparison circuit 14 together with a reference signal voltage obtained at a reference signal voltage generator 13, and the operation of a sound volume adjuster 3 is controlled by turning on and off a gate circuit 15 according to the result of comparison. If a broadcast signal is temporarily interrupted, since a DC voltage from the amplifier 12 is small, an input voltage less than the reference voltage is fed to the comparison circuit 14, which is inverted to turn off the gate circuit 15. When the circuit 15 turns off, since it is provided between a subtraction circuit 10 and an integrator 11, the detected voltage based on the amount of surrounding noise is not transmitted to an integrator 11, resulting that the operation of the sound volume adjuster 3 is automatically stopped. Thus, even if noise is produced in the surrounding, no sound volume is increased and the malfunction increasing noise can be prevented.
