Title: Driving system
Inventor: YAMAMOTO HIROTOSHI
IPC: B25J19/02
Filed: 1987-05-21
Abstract: PURPOSE:To easily improve the resolution of position detection at a low cost by mounting a light reflector formed with the arrangement of a light reflecting pit group on the movable portion side of an actuator and reading the light reflecting pits by a reflection type light pickup. CONSTITUTION:In a direct drive motor 1 as an actuator, when an AC current flows through a stator coil 5, a driven body connected to a flange 13 is driven for rotation by a relative motion between a fixed stator 3 and a rotor 8. A position detector generates a signal corresponding to a relative-positional relationship between the stator 3 and the rotor 8. The light reflecting disc 20 of the detector is formed with linear pits according to a prescribed rule in the surface of a transparent substrate. A light pickup 30 irradiates the disc 20 detecting light focused on it by an automatic focus controller. Reflected light obtained by the reflection of detecting light from the pits is detected and a light detection signal is generated in accordance with a detected result to generate a position detection signal.

Abstract: PURPOSE:To prevent earlier deficiency of insulation film and to increase the number of rewriting, by providing the auxiliary region for charge supply in contact with at least a part or one of one of the source and drain. CONSTITUTION:The SiO2 4 and Si3N4 5 are laminated by bridging the p<+> type source and drain 2 and 3 on the n type substrate 1, and the gate electrode 7 is provided. At the boundary of the films 4 and 5 or a part of the film 5, charges are stored and held 6 and memorized. The layers 2 and 3 are provided with the n type auxiliary region 10 and charges are supplied. The region 10 is present under the gate and the end of the region 10 is present in the depletion layer 11 formed by the layers 2 and 3. In writing in, the layers 2 and 3 are back biased to the substrate 1, spreading the depletion layer under the charge holding means 6 and keeping the layer 10 at the same polarity and same potential as the back bias. The gate 7 is held at the potential close to the substrate 1. Thus, the n type carrier is induced with the different potential from the substrate region on the depletion layer of the substrate surface and the n type carrier is injected to the holding means 6. Accordingly, the bias can be less than the avalanche breakdown, no current concentration is caused and the insulation film is not deteriorated.
