Title: High voltage stabilizing device
Inventor: HAYASAKA JIYUNICHI
IPC: H01F38/42
Filed: 1982-12-10
Abstract: PURPOSE:To realize a high voltage stabilizing circuit sufficiently capable of response to a high voltage change in a fast changing speed by incorporating a high voltage breeder resistor into a flyback transformer at a position where the effect of leakage inductance of the said flyback transformer is less. CONSTITUTION:In the figure, 1 is the high voltage breeder resistor, 14 is a high voltage rectifier diode, 15 is a high voltage cable, 16 is an anode cap, 18 is a ferrite core, 19 is a gap, 20 is a high voltage winding and 21 is a drive winding, 22 is a high voltage breeder resistor storage section, and 23 is a cable connected to a point (e), i.e., variable resistor. A shield wire is used for the cable so as not to generate an induced voltage even if the cable approaches to a coil of the flyback transformer. Since the fitting position of the high voltage breeder resistor is at the uppermost part of the flyback transformer and positioned laterally, the effect of leakage inductance is least and the level gives no problem in the circuit operation. Further, one high voltage cable is enough, since it is connected from a point (a) of the flyback transformer 12 to a point (d) of a cathode ray tube.

Title: Feedback pulse width modulation system analog-digital converter
Inventor: FUJITA TAKAO
IPC: H03M1/56
Filed: 1985-09-30
Abstract: PURPOSE:To provide high speed and high accuracy characteristics by measuring a pulse width within an integration time with the resolution higher than the resolution of the frequency of a clock pulse. CONSTITUTION:Fraction pulse widths DELTAT1, DELTAT2 are extracted by a pulse generating circuit 4 and inputted to a time expansion circuit 5, where they are expanded by N times. Then the pulse widths NDELTAT1, NDELTAT2 expanded by N times in this way are counted by the 2nd counter 6 by using the same clock pulse CLK as that of the 1st counter 7. When the count of the NDELTAT1 is C2 and the count of NDELTAT2 is C3, then the count C1 of the 1st counter 7 and the counts C2, C3 of the 2nd counter 6 are inputted to an operation processing section 9 to operate a value TPW. Thus, the entire pulse width TPW of a pulse width modulation signal PW is measured by the resolution of TO/N. Thus, the resolution of the A/D conversion is increased, thereby resulting that high speed is attained. Further, when the multiple of the time expansion circuit 5 is N, the A/D conversion time Tc is Tc/N, which shows a remarkable reduction.

Title: Inspector for insertion of multi-lead electronic components
Inventor: HIRAI HIROYUKI
IPC: G01R31/04
Filed: 1985-09-30
Abstract: PURPOSE:To enable inspection on whether leads of an electronic component are all inserted into substrate holes or not, by using a plurality of contact pieces with their tips held in such a manner as to approach to and separate from the leads thereof independently. CONSTITUTION:First, when a printed wiring board 2 is mounted on a board positioning holder, a base 6 and a stopper 8 lift suppressing the base part 4b of a contact piece 4 with the stopper 8 and approach the position where leads 3 of a specified electronic component 1 stick out to stand by. Then, as the leads are inserted into substrate holes of the board 2, the stopper 8 moves upward and the base part of the contact piece 4 tilts toward the leads 3 to abut thereon 3. Consequently, a through hole h provided in each of the contact pieces 4 coincides with the optical path of a light source 9a of a transmission type sensor 9, which allows a light receiving element 9b to receive light from the light source 9a to ascertain that the leads 3 are all inserted into the substrate holes of the board 2. Here, when one lead happens to bend, the contact piece 4 corresponding to the lead fails to abut on the lead and hence, the light from the light source 9a is intercepted by the contact piece 4. This keeps the lead 3 from being inserted into the substrate hole.

Filed: 1982-12-11
Abstract: PURPOSE:To produce respective parts with good productivity and good accuracy by shearing and separating a blank material before forging which is molded integrally with the parts to be made into a connecting rod and a cap to said parts with a sintering and forging die and sintering and forging the respective parts. CONSTITUTION:Raw material powder is compression-molded with a plunger die and is sintered in an ordinary way, whereby a blank material 3 before forging having the shape wherein the parts 1A, 2A to be made into a connecting rod and a cap are united to one body is formed. The material 3 is set, as shown in the figure, in a sintering and forging die 9 wherein the upper and lower punches 11 and 16 divided to punches 11 and 12, 15 and 16 having different descending strokes are held afloat by means of springs 14, 18. When the punches 11, 12 are lowered, the part 1A is held by the punches 11, 15, and the part 2A which is sandwiched by the punches 12, 16 descends in this state and is sheared and separated from the part 1A. The rolling force of the punches 11, 12 acts directly on the parts 1A, 2A thereafter and therefore said parts are compressed and are then sintered and forged. The resulting connecting rod part 1 and cap part 2 are subjected to post working.
