Title: Residual heat removal system of boiling water type nuclear reactor
Inventor: FUJII MASAHIKO
IPC: G21C15/18
Filed: 1990-01-19
Abstract: PURPOSE:To improve the reliability of the whole low-pressure water injection mode (LPCI) without losing the functions on the whole owing to a single fault of the LPCI by selecting all recirculation loops unless there is a pressure difference between nuclear reactor recirculation loops. CONSTITUTION:The residual heat removal system has LPCIs 3a and 3b which select sound recirculation loops according to pressure differences between the nuclear reactor recirculation loops and inject emergency cooling water into a nuclear reactor. When neither of the recirculation loops 2a and 2b is broken, namely, when the pressure difference between the recirculation loops 2a and 2b is nearly an instrument error or less than a pressure difference with which sufficient cooling water can be injected into the reactor core even in case of a wrong selection is made, the injection lines 7a and 7b of both the recirculation loops 2a and 2b are lined up. The residual heat removal system makes the injection lines redundant when the LPCIs are the necessary major parts and the reliability of the whole LPCIs can be improved.

Title: Optical receiving circuit
Inventor: KUBO KIYOSHI
IPC: H04B10/60
Filed: 1983-01-20
Abstract: PURPOSE:To improve the distortion and especially the low band distortion of a video signal by setting the value at a level smaller than others for a resistance which is connected to the output end of an amplifier from both ends of a coupling capacitor set between a preamplifier and a photodetecting element via a resistance and has one end connected between a capacitor and an amplifier. CONSTITUTION:For the gate voltage of an FFT12, a DC feedback is carried out by a resistance 19 so as to obtain the best operation conditions and therefore the safety is secured in terms of a circuit. A photodetecting element is connected to the FET12 via a capacitor 16, and the capacitor 16 is put into a feedback loop of a feedback type amplifier 13 to improve the frequency characteristics of a low band. The resistance 19 applies the bias voltage to the gate voltage of the FET12; while a resistance 18 improves the frequency characteristics of the amplifier 13 with the resistance value R1 (resistance 19) and R2 set preferably at R1>R2. Therefore just the application of the gate bias voltage of the FET12 is needed since the DC input resistance of the gate of the FET12 is very large.

IPC: H01M8/06
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a compact fuel reformer good in efficiency. SOLUTION: This fuel reformer 20 is obtained by designing a shift reactional part 32 so as to provide about 40% based on the maximum capacity of a reforming part 30 as the maximum capacity. Air is fed from a blower 46 to a hydrogen-rich gas according to a feed rate in excess of the maximum capacity of the shift reactional part 32 when the hydrogen-rich gas is fed to the shift reactional part 32 at the high feed rate in excess of the maximum capacity. Thereby, an oxidizing reaction of carbon monoxide is carried out in addition to the shift reaction. The concentration of the carbon monoxide in the hydrogen- rich gas at an outlet of the shift reactional part 32 is regulated to a desired concentration or below by controlling the feed rate of the air. As a result, the fuel reformer 20 can be compacted and an energy required for heating up at the time of starting can be reduced.

Title: Highly accurate estimation of basic function
Inventor: SCHMOOKLER MARTIN STANLEY
IPC: G06F7/544
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce the number of times of repetition by accurately estimating a square root, an inverse square root and a reciprocal by calculating an estimated reciprocal through subtracting the product of a normalized input value and a first constant from a second constant. SOLUTION: A full accuracy input (x) is divided into a high-order part xH and a low-order part xL, then the high-order part xH is sent to a look-up table(LUT) 200. The LUT 200 sends a first constant as an inclination to a booth multiplexer 202 and sends a second constant as an offset to a multiplier array/ adder 204. Then, the multiplier array/adder 204 calculates an estimated reciprocal by adding the product of one part of the normalized input value and the first constant to the second constant, or by subtracting that product from the second constant. Thus, a square root, an inverse square root and a reciprocal can be accurately estimated and the number of times of repetition can be reduced.

Title: Manufacture of dishlike matter
Inventor: NAKAYAMA TAKASHI
IPC: B29C45/14
Filed: 1989-01-18
Abstract: PURPOSE:To manufacture a dishlike matter having a high function, by improving facial accuracy by specifying an injection gate diameter. CONSTITUTION:A thin matter 7 is set beforehand to a moving side of an injection mold and the thin matter 7 is fixed at the external fringe part of the mold. Then after the mold is clamped, thermoplastic resin containing the thermoplastic resin or an inorganic filler is filled out into the mold and cooled, a desired dishlike matter can be obtained by breaking the mold. Generally, injection pressure is 40-140kg/cm<2> and particularly 70-120kg/cm<2> is preferable. In addition, it is important that a gate diameter is 6-25mm. When the gate diameter is, less than 6mm, simultaneously with deterioration of flowability of the resin also a value of an index of facial accuracy of the dishlike matter becomes high and gains are lowered suddenly. On the one hand, when the same exceeds 25mm, since a hollow of the gate part of the dishlike matter becomes deep, it is not favorable from a point of a view of an external appearance.

Title: Pilot air regular of carburetor
Inventor: KUBO OSAMU
IPC: F02M1/10
Filed: 1990-01-20
Abstract: PURPOSE:To improve respective operating performance at the time of cold and warm-up operation by installing a thermal switching valve which operates so that it may close at lower temperature than at specified and opens at more than fixed temperature, around an engine unit. CONSTITUTION:Since a thermal switching valve 32 is closed at the time of cold operation, pilot air preset by a pilot air jet 28 is introduced from only the first pilot air passage 24 to supply fuel gas of relatively rich air-fuel ratio. This makes idling stable at the time of cold operation and eliminates engine stop, and improves acceleration performance. At the time of warm-up operation, the thermal switching valve 32 is opened by its heat to open the second pilot air passage 29 and introduce a large amount of pilot air together with the first pilot air passage 24, making the air-fuel ratio of a pilot system lean. It is thus possible to improve fuel consumption during idling and so forth at the time of warm-up and restrain harmful substance discharge.
