Title: Controller of record player
Inventor: ONO TSUYOSHI
IPC: G11B19/20
Filed: 1982-07-09
Abstract: PURPOSE:To attain high speed accessing, by driving a stepping motor with a drive signal having a phase in response to a count number and obtaining pickup position information in response to the count number, detecting the reproducing position of a pickup and controlling the rotation of a record disc with the number of revolutions in response to the pickup objective position. CONSTITUTION:A counter circuit 15 adds or subtracts the count in response to a comparison error signal and a drive signal having a phase in response to the count number is outputted. Thus, the stepping motor 14 is rotated forcedly to the objective address based on this drive signal and the pickup 1 is displaced forcedly to the reproducing position of the objective address. A speed control signal Vi in response to the objective address is extracted with a control signal from an objective value set circuit 19 at the same time. A rotating speed control circuit 13 compares a present rotating speed signal Vo from the record disc 2 with a high speed control signal Vi, and the number of revolutions of the record disc 2 is changed forcedly with a number of revolutions in response to the objective address location of the pickup 1.

Abstract: PURPOSE:To prepare crystal stably by a small-sized device with small power loss, by setting a conductive material plurally wound round the same axis of an airtight container, applying DC to it, carrying out crystal growth in a state where DC magnetic field is impressed on melt heated at high temperature. CONSTITUTION:The silicon melt 1 is put in the quartz crucible 2 contained in the graphite crucible 3, the silicon single crystal 5 is being pulled up, and they are put in the cylindrical airtight container 6. The magnetic field application coil 7 is plurally wound round the same axis of the periphery of the airtight container 6. The coil 7 consists of the conductive material part 8 made of a steel material, etc., the electrical insulating part 9 such as cotton tape, etc., and the cooling water part 10. DC or pulsating current close to DC is impressed on the conductive material part 8 of the coil 7, magnetic field is generated in the silicon melt 1, and crystal is grown in the state. Since sufficient ferromagnetic field can be generated only by the small-sized coil compared with a large-sized electromagnet using a well-known iron core of magnetic material, power consumption can be reduced.

Filed: 1990-05-10
Abstract: PURPOSE:To reduce the effect of rolling on a floating quantity by providing an electromagnetic conversion element on one of three floating faces formed integrally with a metallic oxide sintered body. CONSTITUTION:Floating faces 16, 17 are formed on a front ridge of a floating head slider and chambers 19, 20 for generating a pressure at floating are formed on each front edge. A floating face 18 including a magnetic head element 23 is formed on a rear edge of the floating head slider and floated especially quickly when the recording face is moving at a low speed.

Abstract: PURPOSE:To prevent the damage of ridge lines of track due to projections and dirts on disc surface, by gradually making broader the width of track for recording and reproduction of variable type magnetic head for magnetic disc of monolithic type, from the rear end to the front end. CONSTITUTION:The width between the ridge lines 12,12 of the recording and reproduction track 11 of the variable magnetic head is gradually made broader from the rear end to the front end. The ridge line 14 of the slider shoe 13 is parallel. Further, 15 is magnetic air gap and 16 is coil turn. Thus, the angle of projections and dusts on the disc to the ridge line 12, theta'-theta is, where theta is the angle between the center line of the track 11 and the ridge line 12 and theta' is the angle between the projection P and the center line. Accordingly, the shock to the ridge line of projection can be reduced. Further, to the ratio of the turning speed of disc to the shift speed toward head radial direction, by taking theta as a suitable angle, the collision due to projections and dusts can be avoided.

One 11 among such wires is used as a sample for measuring the temp. and a thermocouple 12 is previously mounted on the tip thereof. The steel wires 3 and 11 are heated by heating withe a heater 6. The plasma of the gaseous Ar is projected from a hollow cathode gun 5 on Ti in a crucible 2 to heat and evaporate the same when the indicating temp. of the thermocouple 12 attains 400 deg.C. Gaseous N2 is simultaneously introduced from a nozzle 7 into the vessel and is deposited by evaporation as TiN on the wires. The steel wires 3 for vapor deposition and the steel wire 11 as the sample for measuring the temp. are taken out and the hardness of the wire 11 is measured upon ending of the vapor deposition. The temp. of the steel wires 3 at the time of vapor deposition of TiN is thereby exactly decided from the relation between the already measured heat history (tempering temp.) and hardness of the steel wire 11.
