Title: Semiconductor laser system
Inventor: ADACHI AKIHIRO
IPC: H01S5/0687
Filed: 1988-11-14
Abstract: PURPOSE:To maintain a fixed oscillation spectrum rays width and obtain a stable laser output by receiving one part of irradiation light of a semiconductor laser which is subject to light feedback by light-receiving means and controlling resonator length of the semiconductor laser so that voltage or current obtained by converting a specific frequency element may be reduced. CONSTITUTION:Irradiation light from a irradiation edge surface 6 at the rear part of a semiconductor laser 1 is reflected by a reflection light 3 and then incides the semiconductor laser 1 again, making oscillation spectrum rays width to be narrow. On the other hand, irradiation light from an irradiation edge surface 7 at the front is separated by a half mirror. Then, one of them is taken out as output light and the other is fed to a light-receiving element 11 and is converted into current. However, since frequency distribution of output current differs, it cannot be detected in in-phase state and a frequency fL which can be detected in out-phase state is set and a frequency/voltage conversion means 12 is set to convert a frequency above it into voltage. Then, output is led to a resonator control means 13 and a resonator deviation means 9 is controlled so that voltage may be equal to 0. Thus, a laser output of a narrow oscillation spectrum rays width can be obtained constantly and stably.

Abstract: PURPOSE:To satisfactorily supply toner by constituting a developer supply member of a foamed elastic body. CONSTITUTION:A wire 4 to give an electric field to toner exists between a photosensitive drum 1 and a developing roll 2. A supply roll 5 and a cleaning roll 3 are arranged around the developing roll 2, and the former supplies a uniform thin layer of toner, and the latter cleans the toner layer for the purpose of preparing for the next development. The supply roll 5 as the developer supply member is a porous sponge roll and is rotated in a toner hopper 12, and thereby, a proper quantity of toner charged by triboelectrification is carried by the porous supply roll 5. When nonmagnetic toner is used as toner, the porousness usefully functions for the carrying force. Further, a desired toner thin layer is obtained by a control roll 6, and a satisfactory uniform thin layer is obtained because the roll 5 has a proper elasticity at the time of contact between the control roll 6 and the roll 5.
