Inventor: HARA TOSHIO
IPC: G01N21/90
Filed: 1988-09-21
Abstract: PURPOSE:To detect a fine flaw regardless of the R-shape of a bottle mouth part by uniformly arranging a plurality of spot opening parts on a predetermined plane in a ring shape and irradiating the bottle mouth part with light in the tangential direction thereof from the diagonal upward position of a bottle. CONSTITUTION:The light detected by a light detection part 1 is transmitted to a light guide part 2. Spot opening parts 4 are uniformly arranged to the spot arrange part 3 divided into a plurality of parts on the single side of a light guide part 2 on the same plane in a ring shape so that a bottle mouth part 6 is irradiated with incident light L in the tangential direction thereof at a proper downward angle from the diagonally upward position of the bottle mouth part 6. By this constitution, when a bottle 6 to be inspected is a good product, the incident light L becomes transmitted light and reflected light but the component of light going to the part above the bottle is not almost present and, when the bottle has a flaw, the incident light L becomes transmitted light L and the reflected light from a flaw part. At this time, the image only of the component going to the part above the bottle in the reflected light is taken to detect a flaw.

Title: Array type semiconductor laser device and manufacture thereof
Inventor: YAMANAKA YUTAKA
IPC: H01S5/00
Filed: 1990-09-05
Abstract: PURPOSE:To minimize the fluctuations in optical output by installing a plurality of light emitting sections capable of driving independently and a non-light emitting section which has an equivalent amount of heating value on the same board on a monolithic basis. CONSTITUTION:This device is provided with two light emitting sections 11 and 12 and two non-light emitting sections 13 and 14. The non-light emitting sections form an active layer which does not emit light easily by intentionally forming a defect on a part of the direction of optical axis or its end face and an amount of heating value equivalent to that of the light emitting sections. When it is necessary to modulate the light emitting section 11, if current switch over between the light emitting section 11 and the non-light emitting section 13 is carried out by means of a switch 15, the amount of heat interference in the light emitting section 12 will be always constant since both the light emitting section 11 and the non-light emitting section 13 are located in the same distance. This construction eliminates the generation of optical output fluctuations even in a constant current drive. it is also possible to enhance the performance by carrying out current switch over with the non-light emitting section 14 by means of a switch 16 if it is necessary to modulate the light emitting section 12.

IPC: G11B11/105
Filed: 1989-09-12
Abstract: PURPOSE:To control the variation in C/N by forming a first dielectric protective layer, recording layer, second dielectric protective layer and metal reflecting layer on a substrate and specifying thickness of each layer to a specified range so as to reduce phase difference in reflected light. CONSTITUTION:The medium has a four-layer structure composed of the first protective layer of 350 - 650 Angstrom  thickness, recording layer of 150 - 250 Angstrom  thickness, second dielectric protective layer of 100 -600 Angstrom  thickness, and metal reflecting layer of 200 - 800 Angstrom  thickness. By this constitution, phase difference due to rotation of polarization plane of the reflected light is made as small as <=15 degrees in absolute value. This almost prevents the reflected light from changing into elliptically polarized light and prevents reduction of the carrier output. Thus, the obtd. medium is hardly influence by the variation in performances of drives, namely, variation of C/N due to drives can be decreased. Thickness of these layers are controlled in a manner that the phase difference shows minimum against variation in thickness of the first protective layer which particularly affects the phase difference, and thereby, time of forming films can be reduced.
