Title: Permanent magnet erasion head
Inventor: HASEGAWA KYOICHI
IPC: G11B5/325
Filed: 1985-03-05
Abstract: PURPOSE:To reduce greatly the noises produced when a head is detached from a magnetic tape by scattering the hard and soft magnetic materials on a tape rubbing surface alternately and adjacently to each other and furthermore increasing and decreasing the magnetic field intensity of those magnetic materials at the entrance and exit sides of the tape respectively. CONSTITUTION:Both N and S areas are formed with rod-shaped soft magnetic materials 2 and powder type hard magnetic materials 1 which are arranged alternately and adjacently to each other. The magnetic field intensity is increased at the tape entrance side and decreased at the tape exit side respectively in each of areas N and S. Thus a gradually reducing alternating magnetic field is formed in the tape drive direction together with an alternating magnetic field in the tape width direction respectively according to the distances between both materials 2 and 1. As a result, the number of alternating magnetic poles is increased and the residual magnetization gets close to a magnetically neutral point after erasion. This improves the S/N. In addition, the multipolarization is carried out also in the tape width direction. Therefore the magnetic fluxes have the components of the directions opposite to each other in a reproduction mode of a reproduction head even though a magnetization pattern is transcribed to a magnetic tape. This reduces the head detachment noises due to an eliminating transfer pattern.

Title: Circuit breaker
Inventor: MATSUDA JUNICHI
IPC: H01H33/59
Filed: 1990-02-23
Abstract: PURPOSE:To generate an alarm signal after occurrence of an overcurrent and a prescribed time before operation of a tripping means and to make it possible to operate a brake circuit by the alarm signal, by executing a tripping operation after a prescribed time since the alarm signal on the overcurrent is generated. CONSTITUTION:A current detecting means 1 detects currents on lines (u), (v) and (w), and when an overcurrent occurs, a determining means 2 generates an output signal. The output signal of the determining means 2 makes a first timer circuit 17 of an alarm signal generating means 3 start the operation. After a prescribed time passes, a relay 24 for alarm operates and an alarm signal is generated. On the occasion, a brake circuit is made to operate by the alarm signal. Simultaneously with the generation of the alarm signal, a timer circuit 25 of a tripping signal output means 5 operates, the tripping means 5 operates with generation of a tripping signal of a signal generating means 26 after a prescribed time passes, and thereby a main contact part 6 is opened. When a short-circuit current flows through the lines (u), (v) and (w), a transistor 36 turns ON and, therefore, the tripping means 5 conducts a tripping operation immediately.

IPC: G02B27/46
Filed: 1981-03-25
Abstract: PURPOSE: To obtain an optical low pass filter which was high performance for double image separation and can be produced in an easy way, by selecting the angle of a slope forming a phase diffraction grating to satisfy the blazed conditions under which the coincidence is obtained between the direction where the beam is tilted by the slope and the direction where the diffractive beam emerges.  
     CONSTITUTION: A grating part comprising a face 2 vertical to an optical axis and a face 3 of an angle α of inclination forms the phase diffraction gratings which are arrayed with pitch P, and the angle α is selected. As a result, the blazed conditions is satisfied to obtain the coincidence between the beam bent by the face 3 and the direction where the diffractive beam emerges. Thus the properties approximate to the double image separating performance of a double diffractive crystal like a quartz crystal, etc. is obtained although the production has some variance. In such a way, an optical low pass filter having high performance for double image separation is obtained without deterioration caused by the polarization and with the facilitated production.

IPC: G01M11/00
Filed: 1988-02-26
Abstract: PURPOSE:To reduce the size of a light signal transmitting unit by disposing a half mirror to one output of laser diodes which constitute a ray group. CONSTITUTION:A CPU 21 applies a signal selection command to a modulation signal generating circuit 22 to generate a modulation signal. This modulation signal is branched to two signals in a branching circuit 23, one output of which is sent to a channel selection circuit 24. The other output of the circuit 23 is inputted directly to the laser diode (LD) 4, by which the light signal modulated in intensity by a modulation frequency is generated in the output of the diode LD 4. This light signal is branched to two signals by the half mirror 27, one of which is entered as a reference light signal via a reference light signal output terminal of the transmitting unit 20 to a reference fiber 61, the other is reflected by a prism 28 via optical switch groups 261-263 and is entered as a measuring light signal via a measuring light signal output terminal to a fiber 62 to be measured. The light signal of the laser diode is branched to two signals and the branched signals are used as the reference and measuring light signals in such a manner, by which the need for a light source to be exclusively used for generating the reference light signal is eliminated and the size of the unit is reduced.
