Title: Underwater motor
Inventor: IWATA MINORU
IPC: H02K5/132
Filed: 1984-12-28
Abstract: PURPOSE:To improve the entire efficiency of an underwater motor pump by gradually varying a suction passage from a suction passage to the pump between a suction casing and a motor frame,and slowing varying the direction toward a motor shaft. CONSTITUTION:When a motor is energized and an impeller 39 is rotated, liquid fed into a suction casing 21 from many suction holes at the lower portion of the casing 21 rises in a suction passage 44. When rising, a flow passage sectional area of an upper flange of a motor frame 1 reduced, but since the flowing velocity is not normally fast here, and almost no flowing loss occurs. When arriving at the inlet of the passage 46 of the upper bracket 2, the flow of the liquid is directed toward an axial center, and the distance from the axial center to the suction passage becomes near. Accordingly, the sectional area gradually decreases to increase the flowing velocity, but the passages 46, 45 are smoothly coupled so that the direction is smoothly varied. Thus, it does not abruptly alter to reduce the fluid frictional loss.

Title: Error detection circuit
Inventor: HATANO SATORU
IPC: H04J3/14
Filed: 1994-11-11
Abstract: PURPOSE: To provide an error detection circuit which can perform the distributed processing for the operation of B3 of a VC-4-Xc path that is stored in the payload of STM-N. CONSTITUTION: A J1 position pulse generation circuit 132 generates a prescribed detection signal 133 based on an AU pointer included in the section overhead of the STM-N signals which are expanded in parallel to each other and at a time point when the J1 byte of a VC-4 path included in the payload is received. The signals 133 are supplied to the even parity arithmetic circuits 122 to 1216 which scatter the data expanded in parallel to calculate the even parity of each bit. Thus the even parity operations equivalent to one frame are dispersedly processed from the head byte of the VC-4 path. These operation results are summarized by an even parity synthesization circuit 13 and the parity data of a single byte is produced. This data is compared with the B3 byte that is separated by a B3 byte separation circuit 136 so that an error is detected.

Title: Capacitor device
Inventor: OKAHARA ATSUSHI
IPC: H05K7/12
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To restrain transfer of oscillation to a clamp board and reduce the noise at the time of operation, by providing a conductive rubber between the clamp board and an insulating sheet. SOLUTION: In an element block 3 of a capacitor, an insulating sheet 8 is provided on both sides of a plurality of capacitor elements 1 which are formed by winding an electrode foil and a dielectric into a flat shape, and a conductive rubber sheet 9 is provided between the insulating sheet 8 and a clamp board 2. The clamp board 2 is fixed by a stud 4. Oscillation transferred to the clamp board 2 from the flat surface of the element, generated by application of an AC voltage, is damped by an internal friction of the conductive rubber sheet 9 when it passes through the conductive rubber sheet 9. Oscillation to a container 10 is also reduced, thereby reducing the noise. The conductive rubber sheet 9 has the same potential as the clamp board 2 by contacting the clamp board 2, and is not required to have insulating performance.  Thus, a sponge rubber including bubbles may be employed and the effect of reducing oscillation transfer may be further improved.

Title: Method for out-pile hydrogen-absorption acceleration
Inventor: TATEISHI HIROSHI
IPC: G01N17/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To realize a test method where the velocity theory of the corrosion of a zirconium alloy material is the same as that in pile and the hydrogen absorption of a base material is generated acceleratedly by allowing a reactor zirconium alloy material to absorb hydrogen in high-pressure vapor atmosphere at a lower temperature than the critical temperature of water. SOLUTION: In high-pressure vapor atmosphere at lower temperature than the critical temperature of water (atmosphere of the temperature at 288-373.95 deg.C, and with vapor at pressure lower than that of the saturated vapor of set temperature), hydrogen is absorbed by a reactor zirconium alloy material. At temperature that is the critical temperature of the water or higher, the water exists only as vapor and becomes superheated steam state or super-critical state, a balanced state of liquid and gas cannot be formed, and the absorption rate of the hydrogen being defined by the ratio of the amount of hydrogen generated from the water by corrosion reaction to that absorbed by an alloy base material cannot exceed 33%. At temperature lower than 288 deg.C, an acceleration test cannot be made since the temperature is lower than in-pile temperature.
