Abstract: PROBLEM TO BE SOLVED: To enable a band operation highly by providing sensing means forming the signals correlated to a vibration mode in an actuator, inducing correction adjusting signals from these signals and combining the adjusting signals and a position signal and feeding back them to the actuator to avoid the limitation of a gain filtering. SOLUTION: A position sensor 36 or a read/write head is connected to a digital servo 40 and the operation of an actuator 26 is limited based on the position of the read/write head. Sensors 32, 34 are connected to an active actuator control 44 via a filter 46 being an arbitrary selection and an acceleration interrupting circuit 48 being an arbitrary selection. The actuator control 44 has a stiffening part 54, an active control part 56 and an inertia reducing part 58 and it induces a stiffening correction, an active braking correction and an inertia reducing correction from signals 52 and these adjustment signals 60 are transmitted to a coupler or an adder 62 to be connected to the digital servo 40.

Title: Superconducting-normal conducting transition type current limiter
Inventor: TEJIMA HIDEKAZU
IPC: H01L39/16
Filed: 1993-04-07
Abstract: PURPOSE:To provide an inexpensive and downsized current limiter which can operate at the temperature of liquid nitrogen and in which the operation starting current can be controlled easily by employing an oxide superconductor and applying a magnetic field thereto. CONSTITUTION:The critical current of a superconductor 1 in a current limiter is controlled by applying a magnetic field from a magnet 2. Since the current limiter begins to function when the short circuit current exceeds the critical current of the superconductor 1 due to failure, the operation starting current of the current limiter can be controlled as designed by regulating the strength of magnetic field at a part applied with magnetic field. Furthermore, the set value of operation starting current of the current limiter can be altered any number of times. This constitution reduces operation cost and realized downsizing.

Abstract: PURPOSE:To detect rapidly the reciprocal of the period of input pulse by presetting a deduction counter and an addition counter by means of input pulse and at the same time controlling the frequency of an oscillator for counting by means of the outputs of both counters. CONSTITUTION:Input pulse is input to a monostable multivibrator MS2 through a monostable multi-vibrator MS1, and at the rise of signal S2 deduction counter CN1 and addition counter CN2 are respectively preset at 2N<-1> and 2N<-2>. By the outputs of a group of terminals of those counters CN1 and CN2, switches S0- SN-1 and W0-WN-1 are turned on, and the output pulse (p) of an oscillator OSC is inputted to the counters CN1 and CN2. The output of the decuction counter CN1 is maintained by a latch LA due to the rise of a signal S1 that is obtained by the next rise of the input pulse, and at the same time it is sent out to outside as digital output. With this arrangement values that are proportional to the reciprocal of the input period, that is the frequency can be obtained rapidly.

Filed: 1986-04-09
Abstract: PURPOSE:To execute local hardening to require both wear resistance and fatigue resistance to a part where hardening is difficult by irradiating a laser beam to a work to alternately produce parts hardened by the laser and temperature parts. CONSTITUTION:The laser beam OAB is irradiated to the surface of the work to form the hard part of the hardened part AB in the thin region under the surface. The laser beam or the work is then shifted by a specified distance until the irradiating parts are partly overlapped. The laser beam O'CD is then irradiated thereto. The hard part of the hardened part CD is formed by such irradiation and tempering is generated in the outside edge part PQRC of the region CD in the region AB by which said part is softened. The hardened parts and tempered parts are alternately produced on the surface of the work by repeating the above-mentioned heat treatment operation. The hardening consisting of the former having the wear resistance and the latter having the fatigue resistance is thus executed.
