IPC: B23K9/12
Filed: 1988-06-28
Abstract: PURPOSE:To carry out control so as to always set a wire at the proper insertion position automatically by regulating the wire insertion position in receipt of the output of a circuit to discriminate the wire tip position. CONSTITUTION:A wire terminal voltage measuring circuit 15 is provided and a position controller 16 to control a wire guide leading the wire 5 to an arc generation part to the proper position in receipt of a voltage signal of the wire terminal voltage of said circuit 15 is provided. It is then confirmed that th wire 5 is in contact with base metal 2 from the wire terminal voltage and then, the proper wire insertion position is confirmed by the wire terminal voltage. When the wire insertion position is deviated from the proper limits, it is moved by one pulse and the terminal voltage is again measured to confirm the wire insertion position and this is repeated till it is set in the proper limits, by which the position of the wire guide can be controlloed up to the proper wire insertion position.

Title: Address decoding circuit
Inventor: HAYASHI SHIGEO
IPC: G06F12/02
Filed: 1993-06-04
Abstract: PURPOSE:To eliminate the need for a setting program for an I/O address and form the circuit to small size by providing a means which indicates a specific address value by using a reset signal, initializing hardware, as a trigger signal. CONSTITUTION:This circuit is arranged in, for example, the extension unit of a personal computer and an address signal, a data signal, a reset signal, etc., are inputted from the side of a main body device. Then when the whole personal computer is powered ON, the reset signal which initializes the hardware of the computer system is outputted from the main body device side. A mapping register 4 is reset with this reset signal and generates an output whose bits are all '0', so that a constant address value is inputted to the input terminal Q of a comparator 1. Consequently, the need for a jumper terminal for I/O address setting is eliminated and the circuit is reducible in size. Further, a program for I/O address setting is unnecessary.

Title: Carrier for electrophotographic development
Inventor: HONJIYOU TOSHIO
IPC: C01G49/00
Filed: 1982-09-13
Abstract: PURPOSE:To obtain a carrier which eliminates the leak of a bias voltage, deteriorates a little, and provides a less-edge picture by using granulated powder having such composition that the mole ratio of oxide of specific metal and Fe2O3 is less than a specific value. CONSTITUTION:Granulated powder which has composition shown by a formula (where M; Li, Mn, Ni, Zn, Cd, Cu, Co, or Mg) and a <=0.85mol ratio X/Y is used to manufacture the carrier for electrophotographic development. This carrier has the amount of electrification nearly equal to that of a conventional carrier formed by the oxidation of iron powder without oxidation and resin coating and is usable in combination with any kind of toner. Further, its resistance can be varied by performing reduction and oxidation adequately. A strong resin film is formed on the surface by resin coating to reduce peeling due to a shock greatly. Thus, the carrier which eliminate the leak of the bias voltage, has less deterioration, and forms a less-edge picture is obtained.

Title: Constant current source circuit
Inventor: INUZUKA TERUO
IPC: H03F3/343
Filed: 1990-06-16
Abstract: PURPOSE:To keep the current value of each unit current source at a constant level by making different the resistance level of an earth wire which earthes each transistor TR forming the unit current source, and therefore making the potential of a TR earthing terminal the same. CONSTITUTION:When the resistance value is set at R1 on a 1st source line SL1 of a MOS TR Q1, the resistance values of the 1st source lines SL2-SL4 of the MOS TR Q2-Q4 are set at R+R2, R1+2R2 and R1+3R2 respectively. Menawhile the resistance values of the 2nd source lines SL02 and SL03 provided among the lines SL2-SL4 are set at R2/2 and R2/3 respectively when the resistance value of a 2nd source line SL01 provided between the lines SL1 and SL2 is set at R2. As a result, all source potentials of the MOS TRs are set at I(R1+3R2) as long as the current value of a unit current source is set at I. Thus each current value goes to the same among plural unit current sources.

IPC: H01L29/06
Filed: 1977-12-28
Abstract: PURPOSE: To manufacture a SITL with its gate-drain capacity made small, by making the SIT drain of N-type doped poly-Si.  
     CONSTITUTION: In N - -type epitaxial layer 2 on N + -type substrate 1, P-type layer 3 and P + -type layer 4 are both formed and drain 8 of the SIT is formed of N-type doped poly-Si. The contact area between layer 8 and P + -type gate layer 4 can be halved in this constitution. As a result, the sum of power delay time can be reduced to half. Further, since the drain protrudes, bad influence upon the potential barrier in the channel is eliminated, so that a high-speed SITL of low power consumption can be formed.

Title: Combustion control system
Inventor: SAWABE UICHIROU
IPC: F23N5/20
Filed: 1977-12-29
Abstract: PURPOSE: In an oil heater, combustion control is performed by introducing a microprocessor. By this, problems that occur at the time of power failure, ignition or extinguishing are controlled each independently in a state where the number of parts, such as resistors, is reduced.  
     CONSTITUTION: When the power supply is turned ON, the voltage of terminal 1N of microprocessor 4 is checked. Here by the discharge time of condenser, time is set either to continue the state of control of the pre-power failure time when power supply is restored after the power failure (S 0 =1), or to change to the ignition cycle after the combustion chamber is cooled (S 1 =0). Next, when US is in operation at the driving switch (US), thermostat S 1  is controlled in accordance with the state of OFF (the combustion chamber temperature is low) or ON (the temperature is high), and the output terminal of S 0  is set at a high level. When US is set at "quench," quenching operation starts with S 0 =1, S 1 =ON. Then, the combustion chamber is cooled and thermostat S 1  becomes OFF, and thereby the operation stops.
