Title: Shift magnet mechanism
Inventor: YANAGIDA SHIYOUJI
IPC: B41J1/30
Filed: 1981-09-04
Abstract: PURPOSE:To prevent variation in the shift position due to wear and tear and a disconnection caused by repeated stress on a leader line of a coil by supplying power to a coil wound on an armature through two elastic wires. CONSTITUTION:A base end of an armature is supported on an anchor member 13 with two conductive elastic wires, for example steel wires 11 and 12. The steel wires 11 and 12 also serves as a conduction channel to a coil and one thereof is connected to the coil while the other thereof to a leader wire 6. The wires 11 and 12 can be mounted in any construction only if the armature is displaced. As a wire is used instead of bearing to support the armature, this eliminates variation in the shift position due to wear and tear and disconnection of the leader wire hardly occurs.

Title: Chattering eliminating system
Inventor: WATANABE SHIGEHIKO
IPC: H03K5/1254
Filed: 1978-11-13
Abstract: PURPOSE:To eliminate the chattering with a small-capacity capacitor by applying the AND circuit of the switch contact signal and the sampling signal featuring a sufficiently high rate to the chattering waveform to the monostable multivibrator capable of retrigger. CONSTITUTION:TW1 is the minimum pulse duration of the chattering occurring at the ON/OFF time of switch S1; TW2 is the repetitive cycle of oscillator OS; TW3 is the maximum duration of the retrigger interval to monostable multivibrator F; and TW4 is the output pulse duration in case vibrator F is operated by resistance R3 and capacitor C2. Now in case the relations of TW1>>TW2 and TW3<TW4 are satisfied at one time, the signal of the ON time of switch S1 is inverted through inverter G1 to be sampled with the signal of OS through AND gate G2. And this sampled signal is supplied to vibrator F with the interval of under TW3. In such way, the contact signal of switch S1 including the chattering can be caught without increasing the capacity of capacitor C2 for elimination of the chattering.
