Title: Correcting and controlling system for head position of disk storage device
Inventor: MOGI EIJI
IPC: G11B21/10
Filed: 1986-07-08
Abstract: PURPOSE:To always perform reading/writing actions with a head kept at a normal position on a track by writing previously servo information on plural disk surfaces to read out this servo information by another head and correcting and controlling precisely the head position based on the off-track value detected from the servo information reading signal. CONSTITUTION:A stepping motor 60 drives a head to a writing position for servo information corresponding to one of reference positions from a prescribed vector revolving direction. Then a servo information writing command SW is delivered to another switch circuit 81 from a processor 90 and the servo data SD is given to the write input W of a read/write circuit 30 from a servo information generating means 80. Then the servo information is written on a disk. The reading signal that read out the servo information out of the head designated by a conversion head selecting command HSS is always given to an off-track detecting means 40 regardless of the state of a read/write command RW. The processor 90 receives the detected off-track value output OS and corrects and controls the head position via a driving circuit 64 and the motor 60 in order to eliminate the off-track value.

Inventor: ASANO MASATOSHI
IPC: F16H48/10
Filed: 1987-06-27
Abstract: PURPOSE:To provide self-braking within a low range of reductive gear ratio by interposing meshingly a gear for load free to swing and rotate between the major dia. cogged part of a differential planet gear with its minor dia. cogged part meshing with a sun gear and a central idling gear loosely fitted on a main shaft.

Filed: 1987-06-30
Abstract: PURPOSE:To enable the realization of an inexpensive package which dispenses with a window by a method wherein a means is provided which sets temperature so as to make the conductivity of a superconductor interposed between a floating gate and a control gate larger than a prescribed value and also potential of the control gate to a prescribed value. CONSTITUTION:In case of erasing a written information, temperature is so set as to make superconductors 11a and 11b superconductive or their conductivity larger than a prescribed value and potential of control gates are set to a prescribed value, for instance, a ground potential. Therefore, floating gates 5a and 5b are made to be of a ground potential through being electrically connected with word wires Wa and Wb through the intermediary of the superconductors 11a and 11b and the control gates 6a and 6b. And, for instance, electrons stored in the floating gate 5a dissipate through the superconductor 11a, the control gate 6a, and the word wire Wa. In this case, all the word wires larger than 2 bit are grounded at the same time, the information of all bit is erased out all together. By these processes, a non-volatile memory of this design can be mounted in a low cost package with no window.

Filed: 1978-12-28
Abstract: PURPOSE: To prevent spring-up by holding the magnetic field current of a motor for driving mandrel at the specific value after the point when the strip has passed through the finishing mill thereby decreasing the armature current in correspondence to the decrease in back tension.  
     CONSTITUTION: At the point when the tail of a strip 7 has passed through the final stand 6 of the finishing mill, the detection signal from a detector 12 causes the output of a tension reference control circuit 16 to decrease by the value corresponding to the amount of decrease having been in a tension decrease amount setting circuit 14. Based on this decreased output value, the armature current of a motor 11 decreases by the specified value corresponding to the decrease amount having been set in the decrease amount setting circuit 14. The magnetic field current of the motor 11 is held at the value of that point and further the output of the tension reference control circuit 16 decreases linearly according to the rate of decrease having been set in the tension decrease rate setting circuit 15 until the coiling ends after the point with the tail of the strip 7 has passed through the final stand 6. Upon ending of the coiling, the power supply to the motor circuit 11 is stopped by a mandrel stop circuit, whereby the coiling is ended.
