Title: Punching device
Inventor: NAKADA KAZUHIKO
IPC: B26F1/44
Filed: 1990-02-07
Abstract: PURPOSE:To prevent the return of a punch chip to the passage of a bored member by forming the edge of a punch pin into an inclined surface, and making the cutting quality of the maximum diameter part in the middle of the inclined surface duller than the cutting quality of the other part. CONSTITUTION:A punch chip 70 is started to cut by the inclined surface top part 2a of a cutting edge 2, and cut out by the inclined surface bottom part 2b of the edge after forming a burr 70 by the dulled part 2b. Then, the punch chip 70 in a hole 4 is tilted according to the inclined surface of the edge 2 of a punch pin 1, and the center of the rotation is laid in the burrs 70b, 70b formed in the maximum diameter part of the inclined surface. The burrs 70 are formed not by cutting by the edge 2, but by being pulled off according to the lifting of the pin 1, and protruded to the inner circumference of the hole 4. When the edge 2 is returned toward a home position shown by a chain line 2A, the punch chip 70 is never moved downward as the burrs 70b, 70b are caught by the inner circumferential surface of the hole 4. Namely, the punch chip 70 at the time of boring is never fallen to a card passage 5 in accordance with the movement of the pin 1.

Title: Wire rod take-up roller
Inventor: MATSUMOTO HIROSHI
IPC: B65H54/28
Filed: 1989-02-07
Abstract: PURPOSE:To automatically correct winding malfunction by monitoring a winding state of wire rods at both ends of a bobbin, judging the winding malfunction, and on the basis of this judgement, controlling a driving means so as to correct the turnover position of a traverser. CONSTITUTION:When the turnover transfer of a traverser 11 is not performed at proper timing, a winding malfunction occurs in and around both sides of a bobbin 20 and thereby there is produced a winding crest. Two sets of distance detecting sensors 51, 52 and 53, 54 are installed in and around both these ends, and when the winding crest is produced, a distance between these sensors 51, 52 or 53, 54 is varied so that it comes to a different detected value. Accordingly, it is judged to be something wrong by a judging means 50 and outputted to a control means 30. Consequently, a motor 13 is controlled so as to cause travel of the traverser 11 to be turned over at a short distance as long as a distance between these sensors 51 and 52 from the next time. When the winding crest is eliminated, the traverser is restored to its original travel range. Therefore automatic adjustment can be thus performed.

Abstract: PURPOSE:To prevent the ineffective consumption of a power source battery after the completion of charging by indicating that a main discharge capacitor is in charge when a converter is in action and stopping the action of the converter when charge voltage of the main discharge capacitor attains the specified voltage. CONSTITUTION:When a main switch SW3 is closed, a trigger circuit 40 attains a operational state in response to the turning on of a cynchro-contact SW4. At the same time, a converter latch circuit A3 attains turning on state. A DC-DC converter 30 starts oscillation, and boosts the low voltage of a power source battery E2, and starts charging to capacitors C5 and C7. A light emission diode L1 is energized and the indication by light emission is made to show that the charging is in progress. When the charge voltage of the main discharge capacitor C7 arrives at a specified voltage, a neon tube Ne2 starts discharging by the charge of the capacitor C5 and the circuit A3 releases on state. Consequently, the current to the light emission diode L1 is cut off, and the DC-DC converter 30 stops operation.

Title: Positioning control method
Inventor: AOYAMA TADAMASA
IPC: G05D3/12
Filed: 1981-03-02
Abstract: PURPOSE:To perform high-precision positioning by subtracting a current position signal, supplied from a length measuring instrument according to the next positioning movement, from an increment movement extent signal supplied in advance, and stopping the movement of a table when an incremental counter shows that the remaining amount is zero. CONSTITUTION:A command part 11 sends an increment signal regarding an expected value from a command value register 13 to a calculator 15 as an expected position signal. The current position of a table is detected by a length measuring instrument 4, which sends a current-position signal to an absolute counter 14 and an incremental counter 16 at the same time, Differences between >=2 expected position signals and the current-position signal passed through the counter 14 are supplied to the counter 16 as signals that show the expeted increase extent of movement. The counter 16 subtracts the current position signal from the expected increase movement extent signal and, when the expected increase extent of movement becomes zero, outputs the signal, thereby positioning the table.
