Filed: 1992-10-29
Abstract: PURPOSE:To obtain a distortion-less spot shape, to improve the quality of a focusing and a tracking error signals and to improve the reliability of information recording/reproducing. CONSTITUTION:In an optical head having a form in which a divergent beam from a laser light source 110 is made incident on light collecting elements 30, 40 through a beam splitter 120 and a reflection type hologram element, the light emitting axis 112 of the laser light source is arranged while inclining to the principal light beam 109 of an optical system and the intensity distribution of the divergent beam is deviated in advance from the principal light beam 109 of an optical system. Or, the entrance pupils of the light collecting elements(objective lenses) 30 40 are intentionally shifted and arranged. Consequently, the deviation of the intensity distribution in the divergent beam caused by interposing the beam splitter and the reflection type hologram element is compensated. Thus, the beam whose intensity distribution is almost symmetric is made incident on the entrance pupil of the light collecting element and a desired spot is formed on the recording medium.

Since one NMOS TR is OFF, the power consumption is reduced.

Title: Method for housing vibrator device and vibrator
Inventor: KUROIWA SHIGETOSHI
IPC: G01C19/56
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To reduce the generation of a compression wave in a medium around a vibrator so as to reduce the effect of the reflected wave of the wave due to the compression wave from a case housing a vibrator by evacuating the case to a vacuum. SOLUTION: Paired piezoelectric elements 2 are respectively stuck to the adjacent two faces of a vibrator 1 which has a square pole body and is supported by U-shaped supporting wires 4 in a case 3. When such a medium as the air, etc., exists between the vibrator 1 and the case 3, the molecules of the medium come into collides with each other and generate a compression wave and, when the wave come into collide with the case 3 after being propagated through the medium, most of the wave is reflected. Therefore, the space between the vibrator 1 and case 3, namely, the inside of the case 3 is evacuated to a vacuum.  When the degree of vacuum is increased and the average free path of the molecule of the medium becomes longer, no compression wave nor its reflected wave is generated, because molecules on the surface of the vibrator 1 do not come into collision with each other, but with the case 3.

Title: Aperture stop for semiconductor laser optical system
Inventor: ITABASHI AKIHISA
IPC: G02B26/10
Filed: 1988-11-18
Abstract: PURPOSE:To obtain the aperture stop for a semiconductor laser optical system which improves the condensability of a laser luminous flux by determining the length and breadth of the aperture part to prescribed sizes and specifying the aperture shape thereof. CONSTITUTION:The contour line of the light intensity on a luminous flux section is elliptical in case of the semiconductor laser 1. The deterioration in the light condensability is caused by being significantly influenced by the diffraction in the four corner parts of the rectangular shape if the luminous flux shape of the laser luminous flux having such light intensity distribution is regulated by the aperture stop having the aperture of the rectangular shape. The length and breadth of the aperture of the aperture stop 3 are, therefore, determined to the prescribed sizes and the aperture shape is formed to a polygon with sides 2n of n>=3 or an oval or elliptic shape. The deterioration in the condensability by the diffraction is then effectively decreased. The laser luminous flux is well condensed onto an imaging plane 7 in this way.

Title: Control method for idle rotation variation
Inventor: ISHIDA TETSURO
IPC: F02D45/00
Filed: 1989-11-13
Abstract: PURPOSE:To limit the decreasing amount of a rotating speed by limiting the generating ratio of a generator if an electric load is abruptly increased when an engine is idling. CONSTITUTION:A regulator 10-3 alters the duty ratio of an exciting current flowing to a field coil FC in response to an electric load capacity. Thus, the current from a generator 10-1 is regulated. In other words, the duty ratio is increased for larger load current and decreased for smaller load current. The duty ratio of the exciting current is detected by an electronic controller 15. When the terminal G of the regulator 10-3 is grounded through a control unit 16 in response to a command from the controller 15, the exciting current flowing to the field coil FC becomes zero so that the generator current becomes zero, and generation is cut OFF.
