IPC: H01S5/22
Filed: 2004-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To manufacture a ridge whose width and height is uniform at the same semiconductor substrate or between semiconductor substrates.  <P>SOLUTION: A polyimide resin film 3 of a heat resistant resin layer is applied to the surface of a gallium arsenide(GaAs) substrate 1, and a stripe-shaped opening 4 is formed at a position corresponding to the formation region of the ridge of the polyimide resin film 3. Then, a GaAs layer 5 being a semiconductor layer as the ridge constituted of the same materials as those of the substrate is grown by a metal organic vapor phase growing method or a molecular beam growing method on the surface of the GaAs substrate 1 exposed from the stripe-shaped opening 4 by using the polyimide resin film 3 as a mask. In this case, a growing temperature at the time of manufacturing the ridge is set so as to range from 425°C to 480°C lower than the decomposition temperature of the polyimide resin. After growth, the polyimide resin film 3 is removed, and the ridge is formed on the GaAs substrate 1. Also, the substrate is configured of not only GaAs but also at least one type of aluminum arsenide (AlAs), indium phosphide (InP), gallium antimonide (GaP) and antimonide (GaSb).  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Optical scanner and image forming apparatus
Inventor: NOMURA YUJIRO
IPC: G02B26/08
Filed: 2004-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical scanner which is small in size and allows a light beam to scan a surface to be scanned at a high speed and an image forming apparatus using the scanner.  <P>SOLUTION: Heat is generated by the friction of a movable plate 653 with air in the optical scanner which oscillates the movable plate 653 at a high speed. While the calorific value thereof is relatively large on a main scanning direction side, the calorific value is relatively small on an oscillation axis side. The light beam is thereupon converged in a sub-scanning direction Y on a sub-scanning plane and is linearly imaged near a deflection mirror surface 651 of a deflector 65. As a result, the dimension of the deflection mirror surface 651 in the the oscillation axis direction (sub-scanning direction) Y is made smaller. On the other hand, a second distance is longer than a first distance on the main scanning side and the movable plate 653 and a perpendicular side part (a second adjacent part) 652b are parted largely in the main scanning direction X. The air resistance to the movable plate 653 is therefore reduced and the calorific value itself is reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
