Abstract: PURPOSE:To make equipment compact and enhance operability by arranging a switching circuit comprising four kinds of semiconductor switches for charge/ discharge and a bypass in a plurality of secondary batteries connected in series to a d.c. power source and an electronic load unit. CONSTITUTION:Secondary batteries B1-Bn connected in series are 7 charged with a d.c. power source 1 by turning on a semiconductor switch Q1 in corresponding switching circuits 3-1-3-n and turning off other semiconductor switches Q2-Q4. When a voltage detecting processing unit 4 turns off the switch Q1 in the corresponding switching circuit and turns on the switch Q3 to bypass the charging current from the battery. When only the switch Q2 is turned on, the batteries B1-Bn are discharged through an electronic load unit 2. The current of the battery whose discharge is finished is bypassed by turning off the switch Q2 and turning on the switch Q4.

Title: Method for manufacturing catch basin
Inventor: NODA HIROSHI
IPC: E03F5/10
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing catch basin by which the catch basin can be easily constructed and its scene can be improved. SOLUTION: The main body 4 of the catch basin is formed of an FRP and, in addition, the connecting pipe section 11 at the lower end of the main body 4 is formed in a bent form, with its front end side being directed in the lateral direction. Consequently, the catch basin can be easily constructed, because the main body 4 can be carried and handled easily due to its reduced weight. In addition, since a drainage pipe is laid in such a way that the pipe is extended closely to the lower surfaces of, for example, floor slabs of a bridge when the lateral pipes of the drainage pipe are directly connected to the front end side of the connecting pipe section 11, the scene is improved.  The bent connecting pipe section 11 is manufactured in such a way that, after the section 11 is formed in a straight pipe, the section 11 is cut halfway obliquely to the axial center of the section 11 and the cut bodies of the section 11 are again coupled with each other by bringing the cut faces of the cut bodies into contact with each other after the front-side cut body is turned around the axial center.

Abstract: PROBLEM TO BE SOLVED: To enable adjusting the stroke of a press in a crank shaft when the press is started by stopping rotation between an eccentric bushing and a press connecting member by connecting both of them and enabling the rotation of the 2nd eccentric member in the 2nd eccentric bushing. SOLUTION: In operation of a usual press, when the crank shaft 14 is rotated, the eccentric bushing 20 is held in a prescribed place of the eccentric part of the crank shaft by press-fixing in the vicinity of the eccentric part of the crank shaft or interference adaptation and, thus, sufficient torque to execute striking or forming motion is transmitted. When oil is supplied to smooth the rotation of the eccentric bushing 20 to a connecting part 10, an oil film on which the eccentric bushing 20 is rotated is formed by passing through a conduit pipe through the head part of the connecting part or the like and flowing into a clearance 26 in the radial direction. The crank shaft 14 and its eccentric bushing 20 revolved together are revolved to the connecting part 10, so the reciprocating motion of a slide is generated.

Title: Input/output buffer device and management method therefor
Inventor: TSUTSUMI YASUNORI
IPC: G06F13/28
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To improve the memory transfer performance by performing control so that data regarding DMA transfer are not held unnecessarily. SOLUTION: A block end detecting circuit 150 detects the final data of a block at the time of DMA transfer and blocks in an input/output buffer devices are invalidated through a control circuit 110, so blocks having small possibility of reuse are not left in the input/output buffer device 100, and can be released early. Further, a DMA end detecting circuit 170 detects data being the tail data of the DMA transfer and then blocks in the input/output buffer device 100 are invalidated through the control circuit 110, so even when a block is not accessed up to the final data, the input/output buffer device 100 can be made ineffective at the end of the DMA transfer. Therefore, the device is invalidated for every used block, so the blocks can be released at early stage and the device can effectively be utilized.

Abstract: PURPOSE:To prevent the generation of chip in the corners of the surfaces of semiconductor device by a method wherein the devices are transferred in a state that an adhesive tape is made to warp upward. CONSTITUTION:Semiconductor devices 1 after diced, frame rings 3 are respectively held by suction pads 7, and in a state that a suction jig 8 holding the whole semiconductor wafer, separately from the pads 7, is brought into contact with an adhesive tape 2, a space defined by the tape 2 and the jig 8, is evacuated to a vacuum sate through a tube 9 so that the pressure in the space becomes from the atmospheric pressure to a negative pressure. In a state that the tape 2 is made to warp upward, the pads 7 and the jig 8 are simultaneously moved and the devices 1 are held and transferred so that the intervals between the device surfaces are made larger than the intervals between the device rears bonded firmly on the tape 2. Thereby, as the adjacent devices 1 are transferred without bringing the corners of their surfaces into contact with each other, chip in the corners of the element surfaces can be prevented from being generated and the yield of the devices 1 can be made high.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To highly accurately measure the position of a moving machine irrespective of the attitude of the machine, by measuring yawing angular speed, pitching attitude, rolling attitude, and speed, and calculating the position of the moving machine based on the angle, attitudes and speed. SOLUTION: An optical fiber gyro 1, a pitching attitude sensor 2 and a rolling attitude sensor 3 respectively measure yawing angular velocity, pitching attitude and rolling attitude. A position-calculating apparatus 5 obtains a yawing attitude based on the information. A speed sensor 4 continuously measures the speed while the gyro 1 and sensors 2, 3 measure the attitude. The position- calculating apparatus 5 further obtains a position of the moving apparatus from the yawing attitude, pitching attitude, rolling attitude and speed. The position-calculating apparatus 5 is adapted to integrate after correcting the yawing angular velocity with the pitching attitude and rolling attitude, and therefore can obtain an attitude of the moving apparatus correctly irrespective of the attitude. Accordingly, the position of the apparatus can also be correctly obtained.
