Title: Method and tool for working precision parts
Inventor: SANENARI TOSHIMASA
IPC: B21J5/08
Filed: 1987-02-28
Abstract: PURPOSE:To reduce manufacturing cost and to improve yield by forming a recessed part for promoting material flow on both end faces of a working stock, then, subjecting to forging by the pressurizing and knockout punch providing the discharging path of a noncompressive medium. CONSTITUTION:In the case of forming a cylindrical outer peripheral face, recessed parts 43a, 43a are formed in advance on both end faces of a working stock 11a by performing forging by using a punch 1C for recessed part forming and a knockout punch 4C prior to the forging. In this case, the recessed part 43a of a working stock 11a on which a truncated conical projecting part 21 is formed at the end part of a head part 20a is easily formed by the punches 1C, 4C. Then, this working stock 12a is subjected to forging by the punches 1, 4 equipped with the discharging paths 44, 45, 51 of a non-compressive medium. Machining is not required at all because of punching being executed after forming the recessed part 43a to reduce the manufacturing cost. Due to the discharging of the medium being smoothed, the generation of flaws is prevented to improve the yield.

IPC: H01L21/822
Filed: 1985-03-08
Abstract: PURPOSE:To prevent error occurrence and reduce man-hours, by mounting an external memory interface circuit on the area in which bonding pads of the number, needed for evaluation chips, are arranged at nearly equal intervals on the surrounding area of a mass-producing chip. CONSTITUTION:A evaluation chip 1 is composed of an area 2, which serves as element pattern and wiring pattern, except on a ROM area, and a surrounding area 3. An address output buffer 5 and a data input buffer 6 are formed at a ROM area 4. Bonding pads 7, increased by the number needed for connecting these circuits to an external device, are mounted at nearly equal intervals on the area 3. Wirings to terminals 8', equivalent to the bonding pads of mass-producing chips, are formed in the same as the mass-producing chips, and the induction to the outside is realized by connecting pads 7 in a new chip. External connection wirings of buffers and connection wiring between new/old pads are limited to the needed minimum generated with reduction of ROMs. By this method, man-hour reduction and error prevention can be realized.

Title: Image forming device
Inventor: KAWABATA TAKASHI
IPC: G03G15/00
Filed: 1995-03-06
Abstract: PURPOSE: To prevent poor image quality due to defective transfer so as to excellently perform image formation on both sides by changing the setting of an output of a transfer preparation charger to a proper value on the basis of detected information for a retransfer toner quantity onto an image carrier. CONSTITUTION: A recording sheet 4 in which copying is carried out on the first sheet face is discharged onto a discharge tray once so as to be collected, and then, the discharged recording sheet 4 is reset in a manual feeding tray or a paper feeding cassette while the first sheet face side is sucked and held onto a transfer drum 3, and subsequently, a copying action on the second sheet face is carried out. In this process, a control unit 62 properly changes outputs of power source units 60, 61 respectively for a transfer corotron 41 and a transfer preparation corotron 14 during image formation on the second sheet on the basis of retransfer toner quantity information detected by means of an ADC sensor 63.  In this way, even when a moisture content of the recording sheet 4 fluctuates after a finish of the first sheet face image formation, no defective transfer due to the fluctuation of the moisture content occurs, and as a result, poor image quality can be avoided.

Title: Magnetic fluid composition and manufacture thereof
Inventor: YABE SHUNICHI
IPC: C10M171/00
Filed: 1987-02-28
Abstract: PURPOSE:To eliminate the detachment of surface active agent from the surfaces of particles due to an external factor, such as the application of an external voltage by using, as a dispersant of ferromagnetic fine particles, a coupling agent for rigid chemical bonding to the surfaces of the particles. CONSTITUTION:Magnetic fluid composition is composed of high boiling point organic solvent, ferromagnetic fine particles dispersed in the solvent, and coupling agent having at least one solvolysis group in addition to an organic group for chemically bonding through the solvolysis group reactive product to the surfaces of the fine particles. Thus, the bonding strength of the dispersive solvent and the fine particles is rigid as compared with a conventional surface active agent which merely absorbs by hydrophilic group and positive and negative charges to the surfaces of the fine particles. Thus, a phenomenon in which the surface active agent is detached from the surfaces of the particles due to external factors, such as thermal influence, mixture of polar solvent, such as acetone or methanol or the application of an external voltage, etc., can be completely prevented.

IPC: F02D29/02
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To give control resetting treatment to a timer operation flag, when in trouble, for constant speed run control to control acceleration/deceleration control output with timer counting treatment. SOLUTION: When an output mode is judged to be a deceleration mode by a eighth step ST8, it goes to a nineth step ST9. When a timer operating flag Ft is judged to stand by the nineth step ST9, it goes to a tenth step ST10. where deceleration output treatment is given. When the timer operating flag Ft is judged not to stand, it goes to a fourteenth step ST14, where system resetting treatment is given. Judgement of an acceleration mode through a eleventh step ST11 is made in the same procedure. When a timer is in trouble, automatic control resetting treatment can be given and so troublesome operation such as reset switch ON can be eliminated.

Title: High-frequency power supply circuit and device for lighting electrodeless discharge lamp
Inventor: YOKOZEKI ICHIRO
IPC: H05B41/24
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of power conversion with a simple circuit by inserting a reverse biased DC voltage between the gate and source of a switching transistor. SOLUTION: In the first secondary wiring of a transformer T1, a power source voltage VDD flows to the ground side via a resistor 4 and shunt resistors R1, R2. When a transistor TR3 is 'off,' a smoothing capacitor C1 is charged with the voltage corresponding to the shunt resistors R1, R2. This charging voltage generates a reverse biased DC voltage between the gate and source of a switching transistor TR1. If the fluctuations of the power source voltage VDD causes the drain voltage of the switching transistors TR1, TR2, for instance, to increase, the base current of the transistor TR3 changes. As a result, the change in the combined resistance value of the parallel circuit of the shunt resistor R2 and transistor TR3 increases reverse biased DC voltages E1, E2 to compensate for the fluctuated portion of the power source voltage VDD.
