Title: Optical pickup
Inventor: NOBUYOSHI TERUKI
IPC: G11B7/135
Filed: 1989-11-30
Abstract: PURPOSE:To attain miniaturization by using the recording face of a recording medium as one end face, constituting a laser resonator of another end face of a laser diode (LD) opposite to the one end face subject to non-reflection processing, and reading information from a change in the oscillating characteristic of the LD due to a return light. CONSTITUTION:Non-reflection processing is applied to an end face 2 of a laser diode LD 21 to make an end face 1 as a reflecting face, the reflecting face of the recording face of the recording medium of an optical disk 6 is formed to be an end face 3 and the faces 3, 1 form a laser resonator. Information is recorded on the face 3 of the optical disk by a change in a reflectance or a polarized face with respect to the irradiating light similarly as a conventional recording and the change causes a change in the oscillating characteristic of the LD 21. The light radiating from the end face 1 of the LD 21 is detected by a photodetector PD 23 in response to the change and the signal is processed to read a recording data. Thus, the optical branch system is omitted to attain miniaturization and the durability and reliability are improved.

Abstract: PURPOSE:To efficiently produce a dead soft steel sheet having good workability at a high yield by subjecting an ingot or slab of a dead soft aluminum killed steel to hot rolling, cooling and coiling under specific conditions, then to hot rolling and continuous annealing. CONSTITUTION:The ingot or slab of the dead soft aluminum killed steel contg. about <=0.01wt% C, about <=0.4% Mn, and about 0.02-0.1% SolAl, etc., is subjected to the hot rolling in which >=1 passes of rolling at >=20% draft per pass are executed in at a least the two-phase region of delta+alpha between the Ar3 transformation point and (Ar3 transformation point -80 deg.C). The hot rolled sheet is cooled at >=10 deg.C/sec cooling rate before coiling after the end of the rolling. The hot rolled sheet is thereafter coiled at a relatively low temp. of 650-600 deg.C. The hot rolled sheet is then subjected to cold rolling, continuous annealing and further temper rolling selectively at about 1-10% draft. The dead soft steel sheet having excellent deep drawability and good workability is thus obtd. by the low-temp. hot rolling and coiling.

Abstract: PURPOSE: To obtain magnetic thin films with which the magnetically permeability between magnetic materials having different shapes and magnetic characteristics is improved with the magnetical loss of the device itself is lessened by limiting the distribution of the saturation magnetic flux density in the magnetic thin films formed on a ferrite within a specific range. CONSTITUTION: The distribution of the saturation magnetic flux density within the magnetic thin films 2 formed on the ferrite 1 having the saturation magnetic flux density B1 (tesla) is so limited that B1, B2, B3 are expressed by the relation B1<=B2<=B3-0.1 (tesla) when the average saturation magnetic flux density of the magnetic materials up to a thickness of 10nm in a direction perpendicular to the film plane viewed from the substrate side is defined as B2 (tesla), the average saturation magnetic flux density of the first magnetic material thin film 2a and the magnetic material thin film 2 described above as B3 (tesla). As a result, the change rate of the saturation magnetic flux density in the direction perpendicular to the film plane is lowered and the transmission efficiency of the magnetic fluxes between the ferrite and the magnetic material thin films is enhanced.

Abstract: PURPOSE:To protect a motor during high and low speed rotation without burning protective relay group, by protecting a pole changing motor through independent protective relay groups during high and low speed operations. CONSTITUTION:In a protector for a pole changing motor(PAM)1, when a power cable 3 is connected with a terminal group 22 and a terminal group 23 is shortcircuited, PAM1 is rotated at high speed side and protected by a protective relay group 51.
