Title: Roof-type groove for o-ring
Inventor: ARAI YOSHIO
IPC: F16J15/18
Filed: 1980-06-02
Abstract: PURPOSE:To lengthen the durability of the performance of O-ring by designating the width of a roof-type groove whose both ends are tapered, to approx. 1.7 times the diameter of the O-ring, and the depth of the groove to approx. 0.7 times the diameter of O-ring at both ends and also to the same as the diameter in the central part.

Title: Method and device for manufacturing helical tooth member
Inventor: MATSUNAGA SHUICHI
IPC: B21J5/06
Filed: 1988-03-28
Abstract: PURPOSE:To reduce the bending stress of a helical tooth profile by using the slag whose cross-sectional area is less than that of a helical tooth member and forming it by extruding in the state of no relative slide between the helical tooth formed on the inner face of a die hole and the slag. CONSTITUTION:The helical tooth profile 35 in the shape corresponding to the helical form to be formed is formed in the die hole 33 of a die 31. The slag 37 whose cross-sectional area is less than that of a helical face member is used, so the slag is not elongated toward the punch side when a punch 41 is pushed into the slag 37. The extruding is performed in the state of no relative slide between the helical face formed on the inner face of the die hole and the slag. At extruding time the stress acting on the helical tooth profile 35 of the die hole 33 is almost a compression stress, so the bending stress acting on the helical tooth profile 33 of the die hole 33 at extruding time can drastically be reduced. The extruding of the helical tooth profile having a large angle of torsion is thus enabled and the service life of a die can be extended as well.

Filed: 1985-04-08
Abstract: PURPOSE:To use the low pressure proof MOS FET by connecting, in parallel, the diode of the constant voltage action between drain sources of the second self arc-extinguishing element to suppress the excessive voltage due to the wiring inductance between the first and second self arc-extinguishing elements. CONSTITUTION:A MOS FET 2 is turned off by an off signal from a gate riving circuit. At such a time, by making a Zener voltage Vz1 of a Zener diode 8 and a Zener voltage Vz2 of a Zener diode 10 into Vz1<Vz2, the electric current, which flows from the collector of a bipolar transistor 1 to the emitter, com mutates to the collector of the bipolar 1, the base, and the channel of the Zener diode 8, and the junction between collector bases of the bipolar transistor 1 is reversely recovered and goes to be off. At such a time, the voltage impressed between drain sources of the MOS FET 2 by the wiring inductances 3 and 4 is suppressed to the Zener voltage Vz2 of the Zener diode 10. Thus, the low pressure proof and large electric current element can be used as the second self arc-extinguishing element.

Title: Reading device
Inventor: KURODA YASUO
IPC: H04N1/04
Filed: 1984-04-16
Abstract: PURPOSE:To attain the accurate read-out of information despite of the deterioration of an optical sensor in sensitivity by comparing the output of the optical sensor with the reference value and controlling the elecrtric power supplied to a light source based on the result of said comparison. CONSTITUTION:A bit terminal Q1 of a shift register SR15 outputs ''H'', and an SW1 is turned on to supply a current corresponding to a resistance R1 to an LED array 3. If the sensitivity of an optical sensor 7 is deteriorated under such conditions, the level of a current ISI flowing to a photodetecting element b1 is reduced. Then the output voltage -VSI rises up to satisfy -VSI>-VREF. A comparator 20 outputs ''H'', and the output pulse of an oscillator 23 is supplied to the SR15 as a shift pulse SH1 through an AND gate 22. Therefore the SR15 shifts the position of ''H'' to a terminal Q2 from the terminal Q1. Thus switches SW1 and SW2 are turned off and on respectively. The base voltage of a TR12 rises and the current flowing to the array 3 increases since R2-R1 is satisfied. This compensates the deterioration of sensitivity of the sensor 7. Then the above-mentioned action is repeated to select the brightness which satisfy -VSI<=-VREF.

SOLUTION: A working fluid containing a conductive powder particle is interposed between an electrode and a workpiece, whereby the conductive powder particle performs the electrophoresis along the power lien between the electrode and the workpiece. This phenomenon is repeated, whereby the conductive powder particle groups partially overlap to form a columnar bridge, and a discharge is generated from the bridge part. At the time of discharge, the columnar conductive powder particle groups are scattered to the workpiece surface to form a conductive surface layer. Thus, a conductive material is adhered to the surface of the nonconductive material, and the working fluid containing the conductive powder is interposed to perform the electrical discharge machining.  According to this, the conductive surface layer is formed in the initial stage, and the formation of the conductive surface layer and the removing work of the workpiece surface layer can be simultaneously progressed at the time of normal discharge.
