Title: Manufacture of semiconductor laser
Inventor: NAKAJIMA TETSUHITO
IPC: H01S5/00
Filed: 1994-10-31
Abstract: PURPOSE: To provide a method for formation of the contact window of a ridge waveguide semiconductor laser in a highly precise manner. CONSTITUTION: A contact layer, an etching layer and an etching cap layer are successively formed on the base layer on which a waveguide is formed. Then, after a stripe-like insulating mask has been formed on the etching cap layer, a spare ridge is formed by conducting anisotropic etching on the region ranging from the etching cap layer to a part of the base layer in the direction of thickness. Subsequently, an aperture part 21 is formed by selectively etching the outer circumferential part of the etching layer part which constitutes a spare ridge. Then, insulating films 26a and 26b, having a step-disconnection at the aperture part, are formed on the exposed surface of the lower layer which is left on the surface of the spare ridge where the aperture part is formed.  Besides, the etching layer part, which is left by selective etching, is removed and a ridge 31, having a contact window 29, is formed.

Title: Track jump preventing circuit of optical disk reproducer
Inventor: HAYASHI YASUHIRO
IPC: G11B7/09
Filed: 1984-12-19
Abstract: PURPOSE:To prevent surely a track jump phenomenon by extracting the low band component after adding the outputs of the 1st and 3rd detectors through a detecting circuit, and controlling variably the open loop gain of a tracking servo. CONSTITUTION:The outputs of subphotodetectors 22 and 23 are added together by an adder 32 for acquisition of a frequency signal approximately equal to an RF signal. The low band component of said frequency signal is extracted through an LPF33 for acquisition of a voltage signal S33 (g). The output S33 of the LPF33 is lowered less than the reference voltage V1 of the 2nd signal comparator 34 when a flaw part is reproduced. Thus the 2nd detection signal S34 outputted from the comparator 34 is shown in a figure (h). Here it is detected that a transparent disc substrate has a flaw. The signal S34 passes (i) through an OR gate circuit 31 as it is for changeover control of an analog switch SW. Thus the open loop gain of the tracking servo is reduced when the flaw part is reproduced. In such a way, the tracking jump scarcely occurs.

IPC: C23C8/44
Filed: 1985-11-29
Abstract: PURPOSE:To form a metallic film having excellent corrosion resistance on a base material by coating a metal on the base material then carbonizing or nitriding the metallic film. CONSTITUTION:The film of the metal (for example, Ti) is formed by a CVD method on a substrate consisting of a carbon steel, etc. This film is the assemblage of the columnar crystal extending from the surface of the base material to the film surface. Since there is a defect at the boundary of the adjacent columnar crystals, a pin hole penetrating to the base material is formed. The formed metallic film is carbonized or nitrided by the conventional method to increase the volume thereof for the above-mentioned method. The defect of the film is eliminated by such increase of the volume. The ceramic film which is dense and contains less defects is thus obtd. The structure is made discontinuous and the penetration defects are further decreased if the multi-layered film are formed by repeating such operation.

Abstract: PURPOSE: To make a feeder small by grasping a mono-filament by means of a collet chuck in the case of the forward movement of a piston in a cylinder provided with a guide port and a supply port of mono-filament and releasing the grasp in the case of a return movement. CONSTITUTION: When air is supplied to a rear part space in the cylinder 1 from an air hole 8, the piston 7 is moved in the direction of the supply port 6.

When a collet ring 11 is abutted on the rear end surface 3a of a front end member 3, it comes off from the collet chuck, the grasp of the mono-filament is released and its progress is stopped. Besides, when air in the cylinder 1 is made to be in a dischargable state from the air hole 8, a spring 1 is abutted on a wall part 12 and the collet chuck 10 is fastened again by the collet ring 11. Thus, a fixed length of mono-filament is successively fed and the feeder can be made small.
