Title: Focus pulling-in device
Inventor: AKAISHI HITOSHI
IPC: G11B7/085
Filed: 1990-03-07
Abstract: PURPOSE:To realize the pulling-in of a focus smoothly, safely and surely by driving a focus actuator in a state that servo gain is lowered for a definite period. CONSTITUTION:When the focus actuator 6 reaches a just focus point, a detection circuit 2 outputs a just focus signal, and a input signal to a driving circuit 4 is switched from the output signal of a waveform generation circuit 1 to the output signal of a focus servo circuit 3a by an analog switch 7. Simultaneously, a timer circuit 8 makes the analog switch 9 activate for a definite period. During this operation, a resistor 304 is connected in parallel with the resistor 303, and the servo gain of the circuit 3a is lowered. Even if the focus error signal of a large level is inputted immediately after the input signal to the circuit 4 is switched to the signal from the circuit 3a, the actuator 6 is pulled-in smoothly, and it can be surely given focus servo.

CONSTITUTION:Electric current flows from anode electrodes 2 to cathode electrodes 3 and magnetic fluxes flow from an N-side magnetic pole 4 toward an S-side magnetic pole 5 and therefore the org. material which is the pulverous diamagnetic material having high electrical conductivity in fluid 9 is attracted toward a diamagnetic material outlet 13 side at the time when the fluid 9 passes between the electrodes 2 and 3. The inorg. material and ash which are the pulverous paramagnetic material are attracted to ferromagnetic wires 6 which are magnetized by N-side and S-side magnetic poles 7, 8 are curved and are formed to have a small diameter on the upper stream side and are formed to have a larger diameter on the down stream side. The inorg. material and ash are thus attracted by said wires 6 as a guide toward the side opposite from the org. material. Fluid 10 incorporated therein with the org. material so as to contain much org. material is directed toward an outlet 13 for the diamagnetic material. Fluid 11 incorporated therein with the inorg. material and ash to contain much inorg. material and ash is directed toward an outlet 14 for the paramagnetic material. The inorg. and org. materials are thus separated.

Filed: 1987-03-12
Abstract: PURPOSE:To simply cancel the component elements without changing the connecting method among these elements by providing previously the valid bits in response to those component elements connected to a queue structure respectively. CONSTITUTION:A queue structure 1 contains plural component elements connected to each other and each of these elements has a valid bit showing its validity or invalidity.

Abstract: PURPOSE:To decrease the number of processes necessary for reinforcing diffusion by doping imurities to a channel region of a FET while also doping impurities to the contact hole forming regions of a source and a drain. CONSTITUTION:A MOS field-effect transistor is preferable for an element which has a shallow source-drain diffusion layer and dopes the impurities of a conduction type reverse to a substrate to a channel region comparatively deep (-0.3mum). The ions of N type impurities are injected using resists 13 as masks and dope layers 14, 20 are formed to the channel region and the contact regions of a source and a drain at a stage when a thin oxide film 12 is made up in an FET such as an N channel type FET. Ions are injected using a poly Si layer 15 as a mask and source-drain diffusion layers 16 are built up, and Al electrodes 19 are formed to the contact hole sections of layer films 18 by means of an electrode forming process and employed as the FET. Thus, the diffusion layers 20 preventing the breakdown of junction can be made up without conducting a reinforcing diffusion process, and the number of processes can be decreased remarkably.
