Abstract: PURPOSE:To stably manufacture a buried-type semiconductor laser whose laser characteristic is good and whose reliability is high. CONSTITUTION:An n-InP buffer layer 102, an InGaAsP active layer 103, a p-InP clad layer 104 and a p-InGaAsP surface protective layer 105 are epitaxially grown sequentially on an n-InP substrate 101 whose main plane is a (100) plane. A stripe-shaped mask 106, for etching use, which is parallel to a <011> direction is formed by a photolithographic method and a dry etching method. The n-InP buffer layer 102 is etched down to the lower part of the InGaAsP active layer 103 by using a mixed solution which contains hydrochloric acid, hydrogen peroxide water and acetic acid; a mesa stripe 107 is formed. Then, the insulating film 106 is removed; the p-InGaAsP surface protective layer 105 is removed by using a mixed solution of sulfuric acid with hydrogen peroxide water; after that, InP current-blocking layers 108, 109 are grown selectively in regions other than the mesa stripe 107 by a liquid epitaxial growth operation; a laser by a buried-type heterostructure is formed.

Title: Casting device for strip
Inventor: HONJIYOU HISASHI
IPC: B22D11/126
Filed: 1984-06-07
Abstract: PURPOSE:To decrease the nonmetallic inclusions remaining in a continuous casting strip and to improve the quality of a product by constituting a casting device for strip of a freely rotatable cooling mold which forms a molten metal to a tubular solidified layer, a device which draws out a solidified layer from the cooling mold and a device which cuts the solidified layer to a strip shape. CONSTITUTION:A vessel 1 and the cooling mold 6 are rotationally driven via a pinion gear 5 and a gear 5 by a driving device 4 and pinch rolls 10, 12 for drawing out are also rationally driven respectively by driving devices 14, 15. The blade 11a of a cutter 11 is set in the prescribed position by a driving device 16. The mold 6 is cooled by cooling fluid and therefore the molten metal 17 is decreased in th temp. by the mold 6 and is co-rotated along the inside group thereof when the vessel 1 and the mold 6 rotate. The tubular solidified layer 18 is thus formed. Since the solidification is effected only in one direction, the nonmetallic inclusions are not attracted into the layer 18. The solidified layer is then drawn out by the rolls 10 and is spirally cut by the blade 11a of the cutter 11, by which the strip 19 is formed. The strip is drawn out by the pinch rolls 12.

Title: Image exposing device
Inventor: HARA YOSHIMASA
IPC: G03G15/01
Filed: 1991-05-22
Abstract: PURPOSE:To form an image in a short time at a higher exposing speed than that at multi-level when the gradation of inputted data is two-level in an image exposing device using a photosensitive recording medium. CONSTITUTION:Two video signal amplifiers 31 and 45 having different gains are provided in the image exposing device which forms a full color image on the photosensitive recording medium based on the image formed on a cathode ray tube. When the inputted data is multi-level, the video amplifier 31 having the smaller gain is used to allow the contrast of the image on the cathode ray tube to coincide with the linear part of the gamma characteristic of the photosensitive recording medium. When the inputted data is two-level, the high contrast video amplifier 45 having the larger gain is used to make the contrast of the image on the cathode ray tube higher to perform exposure, thereby making the exposing time shorter than at the multi-level.
