Title: Single crystal growing apparatus
Inventor: FUJII SHINZO
IPC: C30B15/20
Filed: 1992-12-18
Abstract: PURPOSE:To produce a single crystal having high quality and little crystal defects with an apparatus having a simple structure in a high yield by monitoring the temperature gradient on the interface of a molten liquid in pulling up a seed crystal from the molten liquid to grow a single crystal and controlling the rotational speed in the pulling up of the crystal to the optimum level by the monitored result. CONSTITUTION:The apparatus is provided with a crucible 4 holding a molten liquid 5, a temperature monitor 6 to determine the temperature gradient on the interface of the molten liquid 5 in the crucible 4, a rotary pull-up mechanism 11 to pull up a seed crystal 18 from the molten liquid 5 in the crucible 4 under rotation to grow a single crystal 8 and a rotational pull-up optimizing controller 9 to control the rotational speed of the crystal pulling up with the rotary pull-up mechanism 11. The rotary pull-up mechanism 11 is controlled to a critical rotational speed (a predetermined rotational speed to give a flat interface of the single crystal) or a slightly lower speed by the rotational pull-up optimizing controller 9 basing on the temperature gradient on the interface determined by the temperature monitor 6. A uniform single crystal 8 is grown by this process.

Title: Picture display control device
Inventor: FUJIMOTO TERUHISA
IPC: H04N5/85
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to display computer graphics of non-interlace display on a home TV in a high quality state. SOLUTION: Graphics data for plural lines including lines to be displayed are time-dividedly and alternately read out from a video memory 103, sent to a horizontal scaler 104b and successively applied to horizontal scaling processing. Horizontally scaled data on the same pixel position are vertically filtered by a vertical filter 104C in each data unit of plural lines. Since the horizontal scaling processing and the vertical filtering processing are executed like a pipeline, scaling processing and vertical filtering processing can be efficiently applied to graphics data read out from a video memory without using an off screen area in the memory 103.

Moreover, at a second area where the displacement volume of the hydraulic pump/motor 8 is maximum and another hydraulic pump/motor 7 is held to less than the maximum value, it is kept to a compensation value when the displacement volume of the one side hydraulic pump/motor 8 is maximum at the first area.

Filed: 1993-12-07
Abstract: PURPOSE:To completely prevent foamed resin from coming off cut of a spacer by a method wherein the spacer in a laminated structure, formed by applying plastic films to both sides of a foamed resin base, is made up with heat sealing or adhesion applied partly or entirely. CONSTITUTION:A spacer to be interposed between adjacent pancakes, each of which is made up by winding a magnetic tape round a winding hub, for packaging such pancakes is made up by applying plastic films 2 and 3 to both sides of a foamed resin base 1 and by means of laminate processing in which pressure heat sealing is applied with a heat plate partly or entirely to the obverse and the reverse. A combination of a foamed polystyrene board or a foamed polyethylene board and two high-density polyethylene films or a combination of a foamed polyurethane board and two polyvinyl chloride films is desirable as a material to be used for the laminate processing. As the spacer is made up in a three-layer structure with protection provided to the obverse and the reverse by plastic films, foamed resin can be prevented from coming off. Since the plastic films are in very thin structure, the spacer can be manufactured at low cost.

Since the apex 2 has an angle of advance relative to the other portion of the cutting edge, the cutting edge 3 receives force in the direction of the rotational axis during cutting. Since the cutting edge 3 has a rake angle, it receives force in the direction of cutting into the object. Also the cutting edge 3 has a secondary angle to improve a cutting property. The cutting tool rotating at high speed can obtain satisfactory cutting-in to the object and cutting force by the sum of these force.
