Title: Pad for magnetic head
Inventor: UMEDA AKIFUMI
IPC: G11B17/34
Filed: 1983-09-16
Abstract: PURPOSE:To eliminate the variance between a magnetic disk and a magnetic head as well as a shift of the disk from a signal track by forming a round hollow or a doughnut-shaped hole to a counter surface of a pad to the disk in order to secure stable contact between the head and a recording medium. CONSTITUTION:A pad 3 is attached to a support rod 4 extending in the direction rectangular to the radius of a magnetic disk 2, and a cone-shaped hollow or a doughnut-shaped hole are formed at the center part of a contact surface of the pad 3, i.e., on the counter surface to a magnetic head 1. In such constitution, the pad 3 has circumferential contact with the disk 2 centering on the head 1. Thus the disk 2 receives the pressure from equidistant positions centering on the head 1. Therefore, the head 1 receives the force in its radius direction and functions to restore a tracking shift. The gap part of the head 1 always is in contact with the disk 2 although the head 1 receives the force rectangular to the radius of the disk since the disk 2 is held at the points before and after the head 1. In other words, the head gap part always is in contact with the disk 2 produce a stable reproduction output.

Title: Electrically driven exposing device
Inventor: YAMAMOTO HIROSHI
IPC: G03B9/02
Filed: 1986-07-18
Abstract: PURPOSE:To improve control responsibility and rapid operation and to reduce the weight and size of the titled device in spite of a large aperture by forming a rotor for a motor as a cylindrical body with a small diameter and constituting a motor supporting member of a material not resonating with the motor. CONSTITUTION:Since the rotor 2 for the motor has a small diameter, the inertia mass of the rotor can be reduced, and because coils 12, 13 for a stator can be tightly wound up, the density of magnetic flux can be increased. Thereby, the rotor can be easily started and stopped and rapid responsibility can be attained. Since the motor supporting member 1 is constituted of the material not resonating with the motor, harmful vibration is not generated in the exposing device even if a stepping motor is used. A rotary member 17 carrying a stopping blade is constituted as a decelerating driven gear and large torque is generated by sharply decelerating the rapid rotation of the rotor 2 by the decelerating driven gear 4, so that a stopping device with a large aperture can be driven even if a rapid and small output motor having the rotor with a small diameter is used.

Filed: 1980-12-03
Abstract: PURPOSE:To continue processing without using a buffer storage BS even if the contents of an address register has an error, by sending a coincidence signal only when the contents of the address buffer and those of a buffer address array BAA are coincident with each other. CONSTITUTION:When an error detector 14 detects an error, a comparator 15 supplies a dissidence signal to an AND gate 17 through a line 15b without reference to coincidence between the high-order address bits of an address register 11 and a BAA 12. Then, data from a BS13 is not used and the address of the register 11 is supplied to an MS to output the readout data of the MS through the gate 17 and an OR gate 18. The dissidence signal opens AND gates 19 and 20 to store new data from the MS and its corresponding address in the BS13 and BAA12. Thus, processing is continued by using the data in the MS without using the BS13.

Abstract: PURPOSE:To make the device small by a method wherein a longitudinal-type collector resistor surrounded by a cylindrical p-layer is formed in an N type collector layer on a P type Si substrate. CONSTITUTION:An N+ buried layer 11 is formed on the P type Si substrate 10 and an N-epitaxial layer 12 is piled thereon. If necessary, a poly-Si 5' is allowed to selectively be formed on the part where the collector resistor is formed, after the formation of the layer 11. Then, the n-epitaxial layer 12 is separated by the P-layer 13 to form the cylindrical P-layer 4. As the bar-shape N eptiaxial layer inside the cylinder is used as the collector resistor, the layer 4 must be formed taking enough its diffusion in transverse direction into consideration. Then the P-layer 4 comes in touch with the buried layer 11, there arises no great difference in the value of a resist element to be formed. Subsequently, a P-base 14, an N emitter 15 are formed, an N- resist connection layer 16 is provided and electrodes 1-3 are attached to finish. With the contact of the P-layers 4 and 14, the device can be made smaller, or the diode by the P-layer 4 and the N-collector layer 12 can also be connected in parallel with the collector resistor 5, and only one collector electrode 3 is enough to be provided on a chip surface, thereby enabling the device to be made very small.

Abstract: PURPOSE:To facilitate the easy control of gain and to attain the stable control for drive of an unmanned carrier by separating the carrier speed component and the steering component from the rotational frequency signals of right and left motors. CONSTITUTION:A guide wire 2 is set to a driving course 1 of an unmanned carrier to generate a magnetic field 3. This field 3 is detected by a pair of guide sensors 5L and 5R attached to the body 4 of the carrier. The signals detected by both sensors 5L and 5R are applied to a differential amplifier 6.
