Title: Disk device
Inventor: OHASHI KAZUHITO
IPC: G11B21/02
Filed: 1987-01-13
Abstract: PURPOSE:To reduce the load of a spindle motor, and to execute an access of an optical head at a high speed by controlling a position of the optical head and a heavy object, so that the center of gravity position of the whole rotary part is positioned roughly at the rotation center of a guide rail. CONSTITUTION:An optical head 4 and a balancer 8 can move freely along a slide rail 10. However, the positions of the optical head 4 and the balancer 8 are controlled so that the center of gravity of the total weight of an object (rotary part) containing all of the optical head 4, the balancer 8 and the slide rail 10 is always positioned in the rotation center (the center line of a shaft 14 of a spindle motor 6) of the rotary part. It can be nearly realized by placing the balancer 8 whose weight is the same as that of the optical head, so as to become the same distance from the rotation center. In such a way, an access of the optical head can be executed at a high speed.

Title: Mold forming net
Inventor: YANO MASAYOSHI
IPC: B22D25/04
Filed: 1980-01-19
Abstract: PURPOSE: To form a titled net with the same appearance as that of a woven metal net by forming a mold parting line off the net center to the back side and taking the distance from said line up to a wire diameter size section in each part of both latitude and longitude as a wire diameter size.  
     CONSTITUTION: At the time of molding a mold forming a mold forming net of a metal net shape woven by latitude wire materials 2 and longitude wire materials 3 into one piece at their intersecting parts 4, a mold parting line L is positioned by deviating by a size h in the back side direction of the net from the apparent contact part point A that is, the center O of the net at the intersecting part 4 of both latitude and longitude parts 2, 3. The parts from this deviated line L up to part B of the wire diameter size D of both latitude and longitude parts 2, 3 in the front and back directions are formed to approximately the same size as the wire diameter size D. Since the line L is deviated to the back side direction, the sizes between LWB on the front side are elongated. Here, the sizes between LWB are made approximately the same as the wire diameter size D, whereby the size at which the die is removed at the net forming is obtained.

Abstract: PURPOSE:To contrive the improvement in gate withstand voltage by a method wherein a damage layer formed by ion implantation is provided in the neighborhood of a gate electrode. CONSTITUTION:After a GaAs layer 22 not doped with impurities is grown on a semi-insulation GaAs substrate 21, an Al0.3Ga0.7As layer 23 is grown. A metal serving as the gate electrode 28 is deposited on this epitaxial layer, and then an impurity region 24 is formed by ion implantation by using this electrode 28 as a mask. Next, a source electrode region 25 and a drain electrode region 26 are formed in continuity to the region 24, and further electrode metals 29 and 30 are formed, resulting in the production of an FET. The damage layer 41 is formed in the neighborhood of the electrode 28 by implanting protons with the electrode 28 as a mask. The self-alignment type FET thus formed can alleviate a field concentration in the neighborhood of the electrode 28 end by providing the layer 41, resulting in the improvement in gate withstand voltage.

Abstract: PURPOSE:To reduce the number of the times of an invalidation processing by replacing a distance between vector storage elements with the block size (2<n> bytes) of a buffer storing means and executing an addition when the distance is smaller than the block size (2<n> bytes). CONSTITUTION:An inter-element distance selecting means 5 compares a received inter-vector storage element distance (D) with the block size (2<n> bytes) of block data in a buffer storing means 10, replaces the inter-vector storage element distance (D) with the block size (2<n> bytes) of the buffer storing means 10 when the distance is smaller than the block size, and executes the addition. Consequently, the formation of a useless invalidation request for the same block data can be eliminated. Further, the means 5 compares a generated invalidation address with a vector storage completed block address and detects the completion of vector storage. Thus, the number of the times of the invalidation processing can be reduced.

Abstract: PURPOSE:To prevent effectively the overshooting of a shutter blade or mechanical collision and to obtain stabilized operating state, by applying integrating waveform voltage of a square wave to an electric distortion element in an exposure control device using mechanical distortion generated in the electric distortion element by applying a voltage as a driving source. CONSTITUTION:When a power supply is turned on and a trigger switch 16 is also turned on, a pulse appears from the output of a one-shot multivibrator 12 with pulse width specified by a variable resistor 11 for specifying a shutter speed. The output pulse is turned to amplitude set up by a variable resistor 14 interlocking with a diaphragm ring and a driving pulse for obtaining prescribed shutter seconds and a diaphragm's aperture is outputted from the output of a non-inversion amplifier 13. A square wave integrated by a resistor 15 inserted in series to the electric distortion element 1 is applied to the electric distortion element. Thus, the displacement of the electric distortion element 1 generated by the application of the voltage having a CR integrating waveform is transmitted to the shutter blade and the shutter blade is actuated by following the displacement of the electric distortion element 1 due to the application of the CR integrating waveform voltage.

Title: Intermusic sensor assembly
Inventor: KIKUCHI TAKASHI
IPC: G11B3/095
Filed: 1982-01-18
Abstract: PURPOSE:To detect the intermusic accurately, by adjusting a height of a light shield plate provided between a light emitting element and a photodetector forming an intermusic sensor so as to make the amount of photodetection of a tone arm almost equal at up/down position. CONSTITUTION:The light emitting element 1 and the photodetector 2 are sectioned at a slight shield plate 6 and they are contained in a holder 4. In determining the relation of each position as shown in Figure, the following relation is established; x=(W+w)h1/ (2h2-h1)], where W is the width of the element 1, w is the thickness of the plate 6, h1 is the height of the plate 6 from the photodetecting plane, and h2 is the height of the photodetection plane to a record disc. The x is proportional to the photodetection area and to the amount of photodetection accordingly. An output V of the photodetector 2 is  V=Kx, where K is a proportional constant. The x is increased with the increased h2 and although the photodetection area is increased, the distance between the elements 1 and 2 is increased to decrease the amount of the photodetection. Thus, in selecting the h2 to a suitable value, the amount of photodetection of the photodetector 2 is made almost constant at a certain range of the h1. Thus, the h1 at up/down position of the tone arm is kept within the said range. Then, the intermusic detection level is made constant and the circuit is simplified.
