Title: Torque conversion regulator
Inventor: HAYASHI KENICHI
IPC: F16D35/00
Filed: 1987-02-20
Abstract: PURPOSE:To eliminate a change in limited torque transmitting quantity, and improve the reliability and the general purpose capability, by inserting a second rotary shaft into a first rotary shaft of a hollow cylindrical shape, and filling a viscous liquid having an almost constant viscosity independent of temperature, into a space between the first rotary shaft and the second rotary shaft. CONSTITUTION:A second rotary shaft 2 is rotatably inserted into a first rotary shaft 1 of a hollow cylindrical shape having a closed end. Then, a viscous liquid 3 such as silicone oil having a viscosity hardly dependent upon temperature is filled into a space between both the shafts 1 and 2. The leakage of the viscous liquid 3 is prevented by a sealing member 4. Accordingly, a desired limited torque transmitting quantity may be obtained by regulating a depth of insertion of the first rotary shaft 2 into the second rotary shaft 1. Thus, a change in the limited torque transmitting quantity with temperature and elapsed time may be prevented, and the reliability and the general purpose capability may be improved with a compact structure.

Title: Optical pickup
Inventor: NAKAMURA HIROYUKI
IPC: G11B7/135
Filed: 1987-02-20
Abstract: PURPOSE:To obtain a stable servo control signal and light information signal by forming one face of a concave lens which magnifies the reflected light from a disk and spots the same onto a photodetector to an aspherical face. CONSTITUTION:Light from a semiconductor laser 1 is condensed by an objective lens 3 onto the disk 4 and the reflected light thereof is detected through lenses 13, 16 by a photodetector 7. The one face of the concave lens 13 which magnifies the light spot on the element is formed to the aspherical face. Mapping directions 8, 9 of tracks and the virtual line perpendicular thereto in a spot diagram on the element 7 can be decreased in spherical aberration by the aspherical concave lens 13 and, therefore, said lines coincide with division lines 10a, 10b. The stable servo control signal and light information signal from which the false focus error by a tracking error and disk distortion is eliminated are thus obtd.

Title: Method for testing magnetic bubble memory element
Inventor: SATOU YASUSHI
IPC: G11C11/14
Filed: 1983-03-09
Abstract: PURPOSE:To relieve mis-decision due to improper contactness of a probe by pressing the probe into contact with circuit terminals of a memory element, collating a waveform outputted from a detector of the element not written with a mgnetic bubble and discriminating the propriety of the contact. CONSTITUTION:The contact resistance is measured by pressing the probe into contact with the circuit terminals of the memory element. If the result of decision of a memory element is NO, the measurement is finished at the point of time and if it is OK, the characteristic test is executed. If the result of this test is OK, the element is evaluated as a non-defective element and if the result is NO, the sense waveform is checked. The waveform is checked by applying a strong bias magnetic field to the element so as to annihilate written magnetic bubbles or annihilating all the written magnetic bubbles by an annihilating device 6, thereby decides the disturbance of the sense waveform from a detector 3. If no disturbance exists in the element, the cause to defective memory is in the element itself and the element is evaluated as the defective element. If disturbance exists, the cause is improper contact of the probe and the test is executed again.

Filed: 1994-03-09
Abstract: PURPOSE:To avert failure of a core chip by forming a slit to be inserted and fixed with the core chip in either of supporting parts existing in parts to be formed as right and left two air flowing surfaces. CONSTITUTION:The parts where the right and left air floating surfaces 24 re formed are supported by the columnar supporting parts 16 and are subjected, in this state, to grinding and polishing for the purpose of forming the air floating surfaces 24 and, therefore, a ski-jump effect does not arise at all, unlike heretofore in the production process of this composite type magnetic head. Since the core chip 22 is wound with a coil 26 in the state of holding the core chip with the right and left supporting parts 16a, 16b, the leg parts 30 of the core chip 22 are effectively protected. Consequently, problems, such as failure of the core chip, at the time of coil winding do not arise.

Abstract: PURPOSE:To reduce the man-hour of working of a magnetic head and to reduce the cost of the magnetic head by projecting coherent light to an optical head to position the optical head and projecting the coherent light to the magnetic pole face of the magnetic head thereafter to position the magnetic head. CONSTITUTION:The coherent light is projected to an optical head 4 to adjust the position of the optical head 4 so that the reflected light is obtained, and thereafter, a magnetic head 8 is placed in the optical axis position of the coherent light and the coherent light is projected to the magnetic pole face of the magnetic head 8 to adjust the position of the magnetic head 8 so that the reflected light is obtained. That is, the coherent light is projected to the optical head 4 and the reflected light is obtained to position the optical head 4 on the optical axis of the coherent light, and the coherent light is projected to a magnetic pole face 8M of the magnetic head and the reflected light is obtained to position the magnetic head 8 on the optical axis of the coherent light. Consequently, the optical head 4 and the magnetic head 8 face each other on the same axis. Thus, the man-hour of working is reduced to a half to reduce the cost of the magnetic head 8.

Abstract: PURPOSE: To reduce the size and thickness of a recording and reproducing device as a whole by reducing the numbers of the components and assembling processes of a rotational force transmitting mechanism for the device. CONSTITUTION: An F-R switching lever 51 is supported by a chassis 11 in a swingable state and a shaft 52 is erected from the front end of the lever 51. An oscillating gear 56 is rotatably supported by the shaft 52 and a hole section having the slit of a friction lever 57 is attached to the locking section 52a of the shaft 52 in a detachable state.
