Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To enable the synchronous rotations of plural motors, with a simple constitution by controlling the working speeds of the other motors, based on a signal corresponding to the working speed of a specified motor, out of the plural motors. SOLUTION: Four vibration type motors 342-345 are used for rotationally driving a photoreceptor drum. The rotation speed control of the vibration type motors is executed by speed feedback control based on the number of the revolutions of an encoder. But when the rotation speeds of the vibration type motors are independently controlled with plural control means respectively, it is difficult to attain the synchronous rotations, because of the influence of dispersion caused by a solid difference in the rotational characteristics of the vibration type motors. At this time, for synchronously rotating these photoreceptor drum driving motors 342-345, the output of the encoder for the motor 342 is used for target speeds set by target speed setting parts 605 for the motors 343-345, to attain the synchronous rotations with higher accuracy.

Title: Optical semiconductor element and manufacture thereof
Inventor: SASAKI YOSHIHIRO
IPC: H01S5/042
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To allow control of the phase of a diffraction grating to a desired phase at an end surface by providing a wafer, where a plurality of optical semiconductor elements are formed by cleaving with a cleavage V-groove wherein the phase of the diffraction grating of the optical semiconductor element at the end surface is decided by adjusting its lateral width dimension. SOLUTION: Using EB exposure method, a pattern of a cleavage V groove 102 is exposed in the same process as for pattern exposure of a diffraction grating 101. Here, if a pattern dimension width of the cleavage V groove 102 is set to a length obtained by adding, for example, odd number times of pattern trimming width of the diffraction grating 101 to even number times of mask width, the bottom of a formed cleavage V-groove 102 is matched with the valley of the diffraction grating 101. Thus, if at pattern formation of the cleavage V-groove, a start point for EB exposure is set with a diffraction grating pattern position as a reference and the EB exposure is performed on a decided exposure width, the phase of the diffraction grating at the end face of a cleaved bar is a desired phase based on a decided width.
