Title: Superconducting wiggler
Inventor: KADOI HIDEO
IPC: G21K1/093
Filed: 1990-06-01
Abstract: PURPOSE:To block radioactivity and to reduce the amount of evaporation of cryogenic solution with a low cost by linking and loading plural radioactivity blocking rings in which powder of heavy metal is sintered in ring shape at the outer periphery of a vacuum duct on which a cryostate is located. CONSTITUTION:In a superconducting wiggler, a superconducting coil 3 soaked in the cryostat 5 in which liquid helium 4 as the cryogenic solution is filled is provided, and an electron beam passing the vacuum duct 2 in the inside of the coil meanders. At this time, the radioactivity generated by the electron beam is blocked with a radioactivity blocking layer 6 loaded on the duct 2, which suppresses and blocks the invasion of the radioactivity to the cryostat 5, and the temperature of the helium 4 can be maintained at a satisfactory state. The layer 6 is formed by winding a wire rod of heavy metal with high radioactivity blocking capacity, and the layer is easily formed by applying hot working even when it is of inferior working capability, and is manufactured with the low cost.

Title: Heat exchanger
Inventor: KOMATSUBARA KOUSUKE
IPC: F28F9/00
Filed: 1983-08-02
Abstract: PURPOSE:To disturb airflow around pipes in first row and improve the heat conducting performance of the heat exchanger by providing cylindrical members, having rough outer surfaces, in zigzag with respect to the pipes of the first row. CONSTITUTION:The cylindrical members 5, having cylindrical outer peripheral surfaces and arranged in parallel along the side rim of upstream side of plate fins 1 with intervals into directions intersecting with the flow direction of the airflow, are provided while the outer surfaces thereof are worked into rough surfaces so as to generate strong disturbed flow in the wake flow thereof. The cylindrical members 5 are arranged in zigzag with respect to the pipes 2a in the first row. When air is flowed into the direction A, the airflow is disturbed in the wake flow of the cylindrical members 5 by the same members 5 and eddy currents X are generated. As a result, the airflow around the pipes 2a in the first row is disturbed and the heat conducting performance around the pipes 2 is increased. Further, the outer surfaces of the cylindrical members 5 are rough, therefore, the disturbance is strong and large, therefore, the heat conducting performance as the heat exchanger may be improved remarkably. Ventilating resistance is increased slightly by the provision of the cylindrical members 5, however, most of the ventilating resistance of the heat exchanger, consisting of the plate fins 1 and the pipes 2, is occupied by the frictional loss of the plate fins 1, therefore, the resistance of the heat exchanger due to the configuration of the cylindrical members 5 is not increased so much.

Title: System interconnection protection equipment for inverter
Inventor: OKATSUCHI CHIHIRO
IPC: H02J3/36
Filed: 1993-06-14
Abstract: PURPOSE:To prevent reverse charging by promoting vertical fluctuation of the rated frequency and by stopping the operation of an inverter through the detection of an abnormal state of the frequency caused by the fluctuations. CONSTITUTION:In the case of a delay power factor, if a circuit breaker 7 is opened, then the frequency rises and the current flowing through an inductance decreases and the power factor tends to approach 1. This is detected by frequency detecting circuit 23, and an output having a polarity with phase-lead is applied to an adder 25 by a function circuit 24. Then, a PLL circuit 22 performs a control by a PPL circuit 22 so as to make the output of the adder 25 zero, and thus an inverter current supplies a leading current. Because of this, the frequency rises to balance with the current. The frequency and the rate of frequency change having rapidly risen by the positive feedback effect are detected by a frequency relay 18, a rate-of-frequency change relay 27 and an abnormality detection circuit 19, and the inverter is stopped. By doing this, the inverter is certainly stopped and the reverse charging can be prevented.

Abstract: PURPOSE:To improve hot carrier breakdown strength, and reduce the deterioration of characteristics, by forming a low concentration diffusion region under a gate electrode formed of thermally oxidized silicon film of little surface energy. CONSTITUTION:A silicon nitride film 9 deposited on a polycrystalline silicon film 8 is etched, and coated with a silicon oxide film 11; etching is performed up to above a silicon substrate 1, thereby eliminating a thermally oxidized silicon film 7 and the polycrystalline silicon film 8. By this etching, the thermally oxidized silicon film 7 formed on the side surface of the polycrystalline silicon film 8 turning to a gate electrode is left, and a high concentration diffusion region 6 is formed by ion-implanting method. After the silicon oxide film 11 is eliminated, a low concentration diffusion region 4 is formed by ion-implanting method. Thereby, when electric field concentrates in the impurity diffusion region and hot carrier generates, capture is restrained because a gate oxide film 7 in contact with the low concentration diffusion region 4 is a thermally oxidized film so that an interface level is little.
