Title: Wire cut electrical discharge working method
Inventor: TAKAWASHI TAMIO
IPC: B23H7/06
Filed: 1979-03-15
Abstract: PURPOSE:To facilitate adjustment by performing clearance adjustment of a punch and a die using an angle of a taper and a discharge gap. CONSTITUTION:When a taper portion is required on a working surface, a wire electrode is inclined. Its angle of inclination theta must satisfy an equation: theta=tan<-1> (G-C)/T. Where, the working groove width is G, plate thickness is T, and the desired clearance is C. When an angle of a taper is obtained, the threshold clearance Cmin is obtained from an equation: Cmin=G/2X(1-sin45 deg.). When the desired clearance is larger than the threshold clearance Cmin, the above expression is used. When it is equal to or smaller than it, the relationship between the discharge gap (G-D)/2 and the threshold clearance Cmin is obtained by using the diameter D of the wire electrode 1 as a parameter. This characteristic enables selection of the optimum working conditions.

Title: Strength inspecting device
Inventor: KANEKO SHUNJI
IPC: G01N3/08
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To inspect whether breakage or failure in strength is present or not at protrusions reliably and efficiently in regard to a sintered part with a plurality of protrusions protruded in the same direction to its one end. SOLUTION: At pressing parts 17 and 18, a predetermined force is exerted on the protrusions of a sintered part in the direction in which the protrusions approach each other. By this the protrusions short of strength are bent inward. Next at a diameter offset detecting part 19, a mobile body 65 is fitted between 4 plurality of protrusions. In the case that the protrusion is a non-defective unit, the mobile body 65 can be actually fitted. However, in the case that the protrusion is bent, the mobile body 65 strikes the tip of the protrusion and cannot be fitted. As a deficit in the protrusion cannot be detected by the mobile body 65, an optical sensor 73 further verifies whether each protrusion is present at a predetermined location or not at a part 20 for detecting the presence or absence of protrusions.

Title: Quick charge circuit
Inventor: OKITA HIROTAKA
IPC: H01M10/44
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To quickly charge each kind of battery by obtaining the difference between the voltage immediately after off of a DC pulse supplied to a secondary battery and the voltage in timing slower than it, and comparing it with a specified reference voltage, and changing the current value of a current pulse. SOLUTION: When a secondary battery 5 is connected to a quick charge circuit 1, an A/D converter 6 detects it, and starts charge. A microcomputer 7 outputs the first current value (10C) to a fixed current source 2. Here, C shows the charge current for one hour of the rated capacity of the secondary battery 5. The microcomputer 7, when a timer 8 measures the on time of one second, instructs off to a current switching circuit 4, and performs the charge of 10C for one second. The microcomputer 7, when 95ms pass away, converts the terminal voltage of the secondary battery 5 from AC to DC 6. Next, the microcomputer 7 turns off a current and gets the differential voltage between the voltage V1 of 5ms or thereabouts and the voltage v2 f 95ms or thereabouts (V1-V2), and compares it with the reference voltage.  It repeats the on-off while lowering the 10C value until the differential voltage becomes larger than the reference value. Hereby, each kind of secondary battery can be quickly charged.
