Title: Rotary driving device
Inventor: HAYASHI IKUO
IPC: F16K31/06
Filed: 1983-06-15
Abstract: PURPOSE:To increase an effective magnetic flux through reduction of leak in the direction of axis of a magnetic flux and to increase a rotation force, by a method wherein a part of a yoke is projected to the vicinity of the permanent magnet of a rotor. CONSTITUTION:Projection parts 1a and 1b of a housing yoke 1 are protruded further inwardly from a bridge part 1c, and projection parts 13a and 13b of a top yoke 13 are also protruded inwardly from a bridge part 13c. This causes magnetic resistance in the vicinity of the bridge parts 1c and 13c to be considerably increased over magnetic resistance around a permanent magnet 8. Thus, a magnetic flux, generated resulting from electrification of a coil 11, is effectively exerted on the projection parts 1a, 1b, 13a, and 13b and the permanent magnet 8 to reduce a magnetic flux leading through the bridge parts 1c and 13c. This enables increase of a rotation force exerted on a rotor 7 and provision of high-speed response.

Title: Microstep driver for solenoid
Inventor: SUGANO HIROYUKI
IPC: H01F7/18
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To drive a solenoid to substantially stop at a discretionary position between a magnetizing part and a part to be magnetized, by balancing the cycle of the current flowing through a magnetizing coil and the press of a pressing spring. SOLUTION: When a current is permitted to flow through a coil 2, a magnetic field is generated, and a plunger 1 overcomes the press of a pressing spring 4 and is attracted to the coil 2. On the contrary, when the conduction is interrupted, attraction due to the coil 2 is eliminated, and the plunger 1 returns to the original position by press of the pressing spring 4. When the current is permitted to flow in the form of pulse through the coil 2 and the cycle of the pulses is gradually shortened, the plunger 1 shifts to the subsequent vibration before it completes the vibration of the whole amplitude and the vibration gradually becomes small and stops somewhere. The duty of the pulse is changed and a position where the plunger 1 substantially stops is freely set.  Thus, a multistep diaphragm structure is obtained with a simple structure, a required capacity is reduced and downsizing is facilitated.
