Title: Semiconductor laser
Inventor: MORIMOTO MASAHIRO
IPC: H01S5/12
Filed: 1985-12-11
Abstract: PURPOSE:To reduce crystal defects and a reactive current by a method wherein, after a corrugation is formed on a substrate, an etching stopper layer is formed thereon and a structure like the VSB laser of a conventional Fabry-Perot resonator is formed on the etching stopper layer. CONSTITUTION:The surface of an N-type InP substrate 1 is etched with bromine-based etchant to form an InP corrugation 2 with a pitch of about 200nm. An InGaAsP layer 3 with a wavelength lambda 1.15mum and a thickness of about 0.1mum as an etching stopper layer and a P-type InP layer 4 with a thickness of about 1mum and an N-type InP layer 5 with a thickness of about 2mum as lateral light confinement layers are successively formed on the corrugation 2 by a liquid phase growth method (LEP). Further, a silicon dioxide layer is formed by a chemical vapor phase deposition method. By a lithography process using resist, a stripe window with a width of about 1.5mum is drilled in that silicon dioxide layer in parallel to the direction of <0-1-1>. After the resist is removed, etching is carried out in hydrochloric to form a mesa groove 6 which has an etched surface 6A and the SiO2 layer is removed. An InGaAsP layer 7 as a waveguide layer, an InGaAsP layer 8 as an active layer, a P-type InP layer 9 as a light confinement layer and a P-type InGaAsP layer 10 as a contact layer are formed successively by LPE covering the mesa groove 6. A Ti/Pt/Au layer 11 as a P-type side electrode is formed on the contact layer 10 and an AuGe/Au layer 12 as an N-type side electrode is formed on the backside of the substrate.

Title: Image processing method
Inventor: OKAMOTO SHINYA
IPC: G06T1/00
Filed: 1993-11-09
Abstract: PURPOSE:To reduce image processing time by performing plane approximation according to distance using distance data of a picture element near each picture element of a distance image and then obtaining the amount of change in the distance between the close picture elements. CONSTITUTION:A laser range finder RF scans a laser beam to the front of an automobile and prepares a distance image R1 where distance data D are stored at each picture element. The data D are the function of rotary angles e and d of a two-axis scanner mirror. Performing plane approximation for distance on the image R1 is equal to acquisition of the amount of change in the distance in theta and phi directions which are the horizontal and vertical directions of an image R1. When performing the plane approximation of a picture element in the image R1, eight picture elements near the picture element are used and then the amount of change the DELTADtheta and DELTADphi of the distance between close picture elements are obtained by the method of least squares. The degree of inclination and the inclination of the oblique surface of a position corresponding to the picture element are calculated. These calculation ranges are limited to the image R1 measured by a finder RF, thus reducing processing time.

Abstract: PURPOSE:To maintain uniform electrification and to obtain an excellent copied picture free from picture defects such as a void by maintaining the relation between the 10-point average surface roughness of a photosensitive body and that of an electrifying member under specific conditions. CONSTITUTION:The relation between the 10-point average surface roughness R of the photosensitive body 2 and that RZ2 of the electrifying member 1 is denoted by an inequality, 0.1mum<=RZ1+RZ2<=6.0mum. Provided that, 0.05mum<=RZ1<=5.0mum, and 0.05mum<=RZ2<=5.0mum. Consequently, appropriate rough parts being a discharging start are formed on both the photosensitive body 2 and the electrifying member 1. Since a discharging start voltage falls to improve the electrification capacity of the electrifying member 1, uniform electri fication excellent in a potential characteristic can be performed. Consequently, voids and fogging caused by irregular electrification and picture defects caused by current leak are eliminated to obtain a high quality copied picture. Moreover, the printing resistant life of the photosensitive body is prolonged.
