Title: Image forming device
Inventor: TOMOSADA MASAHIRO
IPC: G05D13/62
Filed: 1983-04-22
Abstract: PURPOSE:To control the inversion of a reciprocating means for scanning a document at the time of multi-stage variable power in a short time by controlling the speed of a movable member in accordance with a pulse for detecting the speed of the movable member for image formation, and when the abnormality of the pulse from a pulse generating means is detected, outputting an error signal. CONSTITUTION:A DC amplifier 34 is actuated by a high level optical system scanning forward signal FAW, a transistor (TR) 35-1 is turned on and a TR35-2 is also turned on. Consequently, current flows through the TR35-1 and the TR35-2 and a motor M2 rotates forwardly to scan a document. An encoder 36 generates pulses E1 having the same frequency as clock pulses CLK driving the motor M2 during the rotation of the motor M2. When the motor M2 reduces its speed, a PLL compares E2 with the CLK and outputs V repeated by the high level H pulse. Therefore, a filter 33 is slightly charged by the pulse and the input voltage of the DC amplifier 34 is risen so that current supply to the motor M2 is increased so as to increase the speed of the motor and when the output of the encoder 36 coincides with the CLK, the output V is stopped.

Abstract: PURPOSE:To effectively control especially the lateral mode by burying a channel on the surface of a substrate by a semiconductor with a refractive index of n1 and sequentially layering layers with refractive indexes of n1<n2<n3, and n3>n4. CONSTITUTION:The channel 10 is formed on N type GaAs6 and is buried by N type Ga1-xAlXAs layer 1 with the refractive index n1. A layer 2 with n2 is placed. N type or P type active layer 3 with the refractive index n4 are sequentially layered. P type GaAs5 is provided. In order to conduct power only the vicinity of the channel, an oxide film stripe 7 is formed, and electrodes 8 and 9 are formed. Since the indexes are determined such that n3>n2>n1 and n3>n4, conductive paths are formed at the layer 4 in the channel forming part, and at the layer 3 outside the channel, and a zero-order mode is interrupted at the part of the layer 3. When the zero-order mode is interrupted all the transmission modes are interrupted at the part other than the channel, and the light can be conducted only at the channel part. By properly selecting the crystal mixing ratio of Al, the basic wave mode can be transmitted only in the channel part, and the lateral mode of the laser can be stabilized.
