Title: Circuit board structure
Inventor: OKAMOTO MASAHIRO
IPC: H05K3/10
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To increase the electric currents made to flow to the circuit patterns of a circuit board structure in which the circuit patterns are provided along a substrate which can be mounted with electronic parts and to suppress the generation of heat from the circuit patterns by constituting the circuit patterns of surface sections formed along the surfaces of the substrate and end face sections which are connected to the surface sections and formed along the end faces of the substrate. SOLUTION: A pair of circuit patterns 20 and 20 is formed along a groove-like through hole 13 formed through a substrate 11. Each pattern 20 has a front surface section 21 formed on the front surface 12 of the substrate 11 and a rear surface section 23 which is connected with the section 21 and an end-face section 22 formed along the internal surface 14 of the hole 13 and formed on the rear surface 15 of the substrate 11 and has a U-shaped cross section over its full length. Therefore, the cross-sectional areas and surface areas of the patterns 20 and 20 can be increased remarkably against the occupying ratio of the patterns 20 and 20 to the surface area of the substrate 11.  Moreover, the electric currents which can be made to flow to the patterns 20 and 20 can be increased and, at the same time, the heat radiating effects from the patterns 20 and 20 can be improved by leaps and bounds. Particularly, the cross-sectional areas and surface areas of the patterns 20 and 20 can be increased remarkably due to the U-shaped cross sections.

IPC: E21D11/08
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To improve the execution property and strength by inserting male metals into female metals buried on the connecting face of a segment when the segments are connected. SOLUTION: Male segments 3 are inserted into the female metals 2 of an adjacent segment 1 for connection at the time of execution. Each metal 2 is welded to an anchor bar and buried in the segment 1, and its front end is exposed to a connection face 11. A comb-like groove is provided at the rear end of a buried section and squeezed, the inside is made smaller in diameter than an exposed section, and the middle is inclined. A cap made of an elastic material is covered on the outside of a small-diameter section to prevent the infiltration of concrete, and the comb-like section is expanded when the metal 3 is inserted. The metal 3 has projections at both ends each constituted of a tapered front face on the outer periphery and a vertical rear face, and the vertical face is locked on the inner diameter section of the metal 2 to prevent an extraction.  A reinforcing sheet is wound on the middle section of the metal 3 to increase shearing resistance. The cost can be reduced lower than for bolt boxes, assembling can be simplified, and the yield strength and chemical resistance can be improved.

Filed: 1993-04-09
Abstract: PURPOSE:To increase the read speed and to improve the linearity of photoelectric conversion characteristics by dividing a photo transistor between a light reception part area or a photo diode and the base area of a bipolar transistor. CONSTITUTION:An anode 10 is initialized divisionally in two stages. At the time of carrier storing operation, the anode 10 of the light reception area is irradiated with light, and the generated carrier is stored in the anode 10 and a base 3. At the time of carrier read operation, a PMOS transistor TR 8 is operated independently of the photo diode because of being in the non-conductive state, and the carrier stored in the base 3 is read out through an NMOS TR 5 made conductive by a pulse phiRD. When one electrode 7 of the NMOS TR 5 is grounded through a load having a low impedance at this time, the accumulated carrier stored in the base 3 is amplified by an NPN TR 1 and is read out. Initialization, storage, and read operations are repeated in this manner to execute the photoelectric conversion operation.

Title: Method and device for controlling transistor as rectifier
Inventor: SHIAN PEI E
IPC: H02M7/21
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a rectifying method and a rectifying device using a SRMOS (synchronous rectifying MOSFET) to minimize the errorneous turn-on/turn-off states. SOLUTION: This rectifier consists of an SRMOS 48, an inductor 50, and a control circuit 40, and the SRMOS 48 is provided with a gate, a drain, and a source. The gate is connected with the output of the control circuit 40, and the drain is connected with the inductor 50. Two detecting trace lines 42 and 44 are used to determine a voltage to be applied between the inductor 50 and the source. When forward characteristic is detected, an SRMOS forward bias allows a current to flow in the SRMOS 48, and when reverse characteristic is detected, an SRMOS reverse bias blocks a current. Hysteresis is used to set the threshold voltages of the forward and reverse biases. When the SRMOS 48 is subject to reverse bias and forward bias, a voltage at a gate terminal (Vgs) is controlled step-wise, so as to prevent the SRMOS 48 from being errorneously turned on/off.
