Title: Optical head
Inventor: NAKAJIMA TOSHIHIRO
IPC: G11B7/135
Filed: 1990-03-02
Abstract: PURPOSE:To facilitate the adjustment of a means for obtaining a super- resolution by disposing a super-resolution grating formed with a phase grating of a phase change type on a transparent or translucent material onto the optical path from a light source. CONSTITUTION:The super-resolution grating 18 made of the transparent or translucent material is disposed on the exit optical axis of a laser diode 16 and plural pieces of groove holes 20 of a certain size are formed at specified pitch intervals on the super-resolution grating 18 to constitute the so-called phase grating 21 of the phase change type. Namely, the laser beam passing the super-resolution grating 18 generates diffraction to generate + or -1st order light. Since the light quantity energy of a main beam (zero order light) is there by decreased, the super-resolution phenomenon is obtd. The intensity, spot diame ter and diffraction angle of the main beam and the ratio of the intensities of the main beam and the + or -1st order light, etc., can be arbitrarily adjusted by properly selecting the size (width, height), depth, pitch, shape, etc., of the groove holes 20. The adjustment of the transmission intensity, etc., for obtaining the super-resolution is facilitated in this way and the mass productivity and yield are improved.

Title: Led head
Inventor: KAMIMURA KATSUYA
IPC: G03G15/01
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To provide an LED head which never deteriorates image quality even when high-density printing is executed. SOLUTION: The LED head has an LED substrate, an LED array 32 having a plurality of LED elements loaded adjacent to each other linearly thereon, and an LED driver supplying electric energy to each LED element and letting light-emitting parts 37, 38 of each LED element emit light. A width w2 of the light-emitting part 28 is narrower than a width w1 of the light-emitting part 37. When the width w2 of the light-emitting part 38 is set narrower than the width w1 of the light-emitting part 37, a distance u3 is sufficiently secured regardless of an error when the LED array 32 is cut. Therefore, the light emitted perpendicularly to a surface of the LED array 32 from the light-emitting parts 37, 38 never leaks towards an end part of the LED array 32 from the light-emitting parts 38.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent an overspeed of a primary turbo-supercharger related to rise of an engine speed due to a down shift, when a shift of a manual speed change mode is lowered down by operation of a driver under a single turbo condition. SOLUTION: When a manual speed change mode is selected to lower down a shift by a driver under a single turbo condition, a rotational speed decision threshold NT2 for determining switching from a single turbo mode to a twin turbo mode, by comparing with an engine speed N is set by map reference based on the engine speed N, when a shift down is started, gear position GEAR when the shift down is started and a number of shift down times DWN (S21). The engine speed N and the rotational speed decision threshold NT2 are compared (S27), when a relation is N<NT2, single turbo mode control is maintained, when the relation is N>=NT2, the control is transferred from single to twin switching control, to prevent overspeed of a primary turbo-supercharger.
