Title: Semiconductor device and its manufacture
Inventor: SUZUKI TAKASHI
IPC: H01L21/76
Filed: 1995-03-31
Abstract: PURPOSE: To provide a semiconductor device with a trench having a smooth corner section so as to prevent the occurrence of crystal, defects. CONSTITUTION: The upper part of a trench 2, formed in a semiconductor substrate 1 near the surface of the substrate 1 is formed in a tapered V-groove 17 which expands toward the surface of the substrate 1 and the lower part 18 of the trench is formed by further extending the bottom section of the groove 17 downward into the substrate 1 in the vertical direction. The groove 17 is formed by etching the substrate 1 with an alkaline etchant. The lower part 18 of the trench 2 is formed by using the RIE method after the groove 17 is formed. The bottom part 19 of the trench, in addition, is formed in a round shape by reflecting the V-shape of the bottom part of the groove 17. Therefore, the occurrence of crystal defects can be prevented at the time of oxidation treatment, etc., because the concentration of stresses to the corner sections E and bottom section 19 of the trench 2 can be relieved.

Title: Balanced transmission line
Inventor: HARA TOSHIHIKO
IPC: H05K1/02
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent an unbalanced current from being supplied to other lines than a balanced transmission line consisting of a couple of signal transmission wires used for a display device and through which a small amplitude differential signal is transmitted. SOLUTION: A common mode filter 3 is placed to a transmission line 2 wired on an FPC 1 connected between an LCD panel 4 and a board 5 on which an LCD drive circuit is mounted. Thus, even when an impedance between a grounded metal 7 and one of two wires of the transmission line 2 is lower than an impedance between the two wires because of a stray capacitance 9, because an impedance is inserted between the grounded metal 7 and one of the two wires of the transmission line 2, an unbalanced current 8 flowing to the metal 7 through the stray capacitance 9 is reduced because of the presence of the filter 3 even when the wire approaches the metal 7, thereby reducing radiation noise.

Title: Circuit for adjusting position of screen in perpendicular direction
Inventor: KODAMA SHUICHI
IPC: G09G1/04
Filed: 1988-03-28
Abstract: PURPOSE:To automatically adjust the position of a screen in a perpendicular direction by selectively conducting switching elements in accordance with the switching signals inputted in association to a vertical synchronizing signal. CONSTITUTION:An input terminal 18 and an output terminal 15 conduct and a transistor 20 turns on to lower the potential at the point A when the switching signals of L and H are respectively inputted to switching signal input terminals 13, 14. On the other hand, the terminal 18 and an output terminal 17 conduct and a transistor 22 turns on and the TR 20 turns off when the switching signals of H and L are inputted thereto. The potential at the point A, therefore, rises by as much as the voltage drop of a resistor 23. Both the TRs 20, 22 turn off and the potential at the point A rises by as much as the voltage drop of the resistors 23, 24 when the switching signals of L and L are respectively inputted to the terminals 13, 14. The potential at the point A is thereby changed accordingly at every change of the switching signals of the vertical synchronizing signal, by which the charging and discharging currents of a capacitor 2 connected to a vertical deflecting coil 6 are controlled and the position of the screen in the perpendicular position is automatically adjusted.

Title: Brush unit for small motor
Inventor: YOSHIDA MAKOTO
IPC: H01R39/39
Filed: 1978-06-23
Abstract: PURPOSE: To simplify the machining of a leaf plate and prevent a brush to be inserted into the hole of the leaf plate from being damaged by forming the leaf spring and the brush so that the hole of the leaf spring may be partly superimposed in sectional shape with the heat of the brush, inserting the head of the brush into the hole of the plate while cutting the brush, and fixing the brush to the plate with conductive adhesive.  
     CONSTITUTION: The hole 2 of a leaf spring 1 and the head 3a of a brush 3 are so formed in sectional shape that one is rectangular and the other is in drum shape or  in saddle shape in a manner that, when the hole 2 is assembled with the head 3a,  the former is partly superimposed with the latter, the head 3a is inserted into the  hole 2 while cutting the head 3a, and the head 3a is then fixed to the hole 2 with a  conductive adhesive 4. Since the hole 2 can be thus pressed simply, it can simplify  the cutting step and eliminate application of large pressing force to the head when  inserting the head 3a into the hole 2 to thereby prevent the brush 3 from being  damaged.

Abstract: PURPOSE: To suppress the generation of plate camber by providing a quantity measuring type plate camber sensor on at least one side of the inlet and outlet sides of a rolling mill and executing light reduction rolling at the final pass when the measured plate camber exceeds the allowable critical value. CONSTITUTION: The signals from the fixed quantity type camver sensors 5 provided on the inlet and outlet sides of the rolling mill for rolling a material 1 to be rolled are fed through a a signal converter 7 to an arithmetic unit 8 with which rolling reduction of the next pass is calculated and control is executed with a screw-down controller 9.

Title: Controlling method of current for welding accompanying short circuit
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/073
Filed: 1983-04-30
Abstract: PURPOSE:To decrease generation of spatter and to improve working efficiency by making welding wire current nearly zero for a specified time in the initial period of a short circuit, increasing the same after a specified time and making the current lower than the same after an adequate time. CONSTITUTION:Welding wire current is maintained at the 1st value close to zero for the specified time only in the initial period of a short circuit and the value thereof is set at the substantially low value at which the arc is not generated even if the contact area between a droplet and the molten pool is small right after the short circuit in short circuit transfer welding. The current is then set at the large 2nd value and is set according to the feed speed of the welding wire after a specified time. The value is decreased to the 3rd value smaller than the 2nd value after an adequate time and said value is maintained. The preliminary sign for regeneration of the arc is detected and the vaue is decreased further down to the value smaller than the 3rd value when the arc is regenerated. The current decreases just before the regeneration of the arc is thus effectively accomplished and the generation of the spatter is decreased.
