Title: Coil forming device of galvanized iron wire
Inventor: ISHIKAWA KOUJI
IPC: B21F3/04
Filed: 1978-12-14
Abstract: PURPOSE:To form the coils of the same shape without waste up to the end by subsequently winding rotating metal wire curved pins around a winding core. CONSTITUTION:A metal wire material W is supplied for the specified length along the guide part 13a of a guide plate 13. A circular cylindrical stem body 15a is slided in a sleeve 18 and a winding core 15b is protruded from a guide plate 13. When the circular cylindrical stem body 15a and revolving shaft 32 approach most, the winding core 15b fits into the 32c provided to a revolving shaft heat part 32b. As the winding core 15b moves, the metal wire is bent with the lower radius surface of the metal guide 14 as a fulcrum, whereby the coil neck part A1 is formed. Following to this, a motor starts running, causing the revolving shaft 32 to revolve in the Q direction. Hence, the metal wire material W is first pre-bent by the 1st pin 33a thence correctly bent along the outer edge of the winding core 15b by the 2nd pin 33b and is coiled up to the final end A2 of the metal wire material W, whereby the coil A is formed.

Title: Protective cover for fuel pouring hole
Inventor: OSAWA HIROBUMI
IPC: B60K15/04
Filed: 1986-07-04
Abstract: PURPOSE:To prevent a damage of a car body panel owing to a fuel feeding gun, by connecting a receiver to be developed freely to receive the fuel feeding gun, at the installing part of a fuel pouring hole protective cover. CONSTITUTION:This protective cover is composed by connecting an installation part 10 and a receiver 11 made of metal plate, through a hinge 12, and a rubber stopper 15 is furnished at the receiver 11. When the cover is used for fuel feeding, the receiver 11 is developed at the lower side, and then a cap 3 is removed from a pouring hole 6, to be hooked to a fixing hole 16 of the receiver 11. Then, while the nozzle of a fuel feeding gun 5 is inserted to the pouring hole 6, the gun 5 is placed on the receiver 11 from the upper side of the cap 3 to feed the fuel. Therefore, the gun 5 never contacts directly to the car body panel 1, but the rubber stopper 15 contacts thereto. Consequently, a damage of the car body panel can be prevented.

Title: Manufacturing method of shadow mask
Inventor: KIDO FUSAKICHI
IPC: H01J29/07
Filed: 1978-12-20
Abstract: PURPOSE:To obtain a fluorescent face having uniform brightness by determining the shift between large and small rectangular patterns while considering the inclining angle due to the curvature of shadow mask after press work and the incident angle of electron beam. CONSTITUTION:After forming photo-sensitive films 22, 23 on both faces of shadow mask material 21, original negative plate 25 for small rectangular printing pattern and original negative plate 27 for large rectangular pattern are located while shifting the centers of said patterned sections 24, 26, then printing, optical hardening and etching are performed to form rectangular opening 27.

Title: Automatic clear circuit
Inventor: YOKOYAMA KOUZOU
IPC: G04G5/00
Filed: 1978-12-15
Abstract: PURPOSE:To produce the automatic clear signal excellent in the noise proof performance and small in error, by using the delay time for the output response due to the time constant of the boosting circuit. CONSTITUTION:The gates G1 and G2 of the boosting circuit 1 are conducted at the low level of the clock outputted from the frequency demultiplier 6 and the gates G2, G4 are conducted at high level. Thus, the capacitor C1 is charged with the time constant of the resistor of the gates G1, G2 and the internal resistor of the battery E, and the charging up voltage of the capacitor C1 is discharged to the capacitor C2 and distributed with the time constant of the similar resistors of the gates G2, G4. As a result, high level output sets D-type FF3 after the time T in response to the time constant of the circuit 1 to the application of power supply by the switch 8 from the level down circuit 2 to which the threshold value voltage is set. Thus, via the latch circuit 4 producing the output delayed by a half period than the clock and the leading detection circuit 5 consisting of NOR gates, the automatic clear signal is accurately produced with the clock shifted by a half period through the response delay for a given time at the application of power supply having many noises.
