Title: Optical storage device
Inventor: SANO KOUICHI
IPC: G11B7/003
Filed: 1984-06-29
Abstract: PURPOSE:To increase the information density of a recording medium per unit area by scanning a laser beam crossing slantingly the moving direction of the recording medium, and forming tracks at right angles to the moving direction of this recording medium. CONSTITUTION:The laser beam reflected by a reflecting mirror 17 changes the direction of irradiation to the recording medium 14 while maintaining polarization of 90 deg., and the laser beam is scanned on the recording medium 14 while crossing its moving direction slantingly. At this time, the laser beam before being reflected by a rotary mirror 12 slants at an angle alpha to the moving direction of the recording medium 14, the scanning direction of the laser beam deviates by the angle alpha from the direction perpendicular to the moving direction of the recording medium 14. The recording medium 14, however, moves at a specific speed, so a time lag corresponding to the movement during the scanning of the laser beam is generated and there is a deviation generated between the scanning direction of the laser beam and the direction of track formation and tracks are formed at right angles to the moving direction of the recording medium 14.

Title: Driving system for semiconductor laser
Inventor: TOUFUKU ISAO
IPC: H01S5/00
Filed: 1981-08-27
Abstract: PURPOSE:To perform a precise self-control of a wavelength of emitting light, by a method wherein a part of laser light, whose wavelength is selected, is detected by a collection element, a driving current for laser is controlled by said detecting output so that a light output is maximized in terms of a given wavelength. CONSTITUTION:A part of radiating light is introduced to a microcomputer 13 through a first photo detector D1 immediately before laser light is radiated from a detector. A laser driving current value I0, bringing a maximum value P1, is stored in a memory circuit 14 of the microcomputer 13. In case laser radiation light, which is displaced in a wavelength, passes a difraction grating G, a light power is reduced to P2. If the light power, brought to P2, is detected by a first photo detector, it is compared with a light power set to P1, and it is immediately decided that irradiating light is displaced in a wavelength. Thus, the microcomputer 13 controls a constant-current power source through a laser driving current to work so that spread of irradiating light is narrowed to the original. This enables to perform a precise self-control of a wavelength of emitting light.

Filed: 1989-05-29
Abstract: PURPOSE:To enable the consecutive recording with high accuracy by starting the recording by detecting directly a picture recording termination point with a control signal of a changed duty ratio recorded on a tape. CONSTITUTION:N-number (N>=1) of control signals having the duty ratio changed at the recording termination is recorded by a recording-ending-time control-signal control means 2, and at the time of the consecutive recording, the control signals under the changed duty ratio are regeneratively detected by a control signal duty ratio detecting means 6 so as to start the recording, and at the same time, they are rewritten into the control signals of the normal duty ratio but remaining n-number (n<N) of the control signals unchanged by a control signal recording means 7. Consequently, N-number of the control signals under the changed duty ratio are written in the last recording terminal position, while n-number of the control signals under the changed duty ratio are written in a consecutive recording position. By this method, the accuracy of the consecutive recording is enhanced, and useless overwrite parts are reduced so that editing work can be facilitated.

Title: Electrostatic charge image developing carrier and developer
Inventor: TAMURA KISHIOMI
IPC: G03G9/10
Filed: 1995-06-01
Abstract: PURPOSE: To suppress uneven image density or decrease in density and to obtain an output image having high density and uniform and high resolution by preparing core particles from a mixture of spherical particles and irregular particles and specifying the mixing ratio on the basis of numbers of spherical particles to irregular particles. CONSTITUTION: This carrier for electrostatic charge image development is prepared by coating surface of core particles with a polyolefin coating layer. The core particles consist of a mixture of spherical particles and irregular particles with the mixing ratio of spherical particles to irregular particles on the number basis is 95:5 to 60:40. When the irregular carrier particle touches another carrier, the probability of the edge part of the irregular particle in contact with another carrier is high so that the edge part where the core surface is exposed without the resin coating film has an effect to leak the charge accumulated in the other carrier in contact with. Thus, by properly controlling the amt. of the edge part in the developer, accumulation of charges (charge-up) which is a problem for a polyolefin resin-coated carrier can be suppressed, and therefore, uneven image density or decrease in density can be suppressed.
