Title: Semiconductor laser
Inventor: SEKII HIROSHI
IPC: H01S5/00
Filed: 1987-10-14
Abstract: PURPOSE:To make the effective refractive index change gently in the direction of a junction to expand a region where a fundamental mode stably operates, and enable the high output operation of the fundamental mode, by forming an active layer flatly, and changing the the thickness of crystal layer in a multilayer type or an inclination type. CONSTITUTION:By processing twice the trench of a substrate 1, the thickness of a N-AlyGa1-yAs clad layer 2 is gently changed. The trench processing is performed, for example, as follows. Firstly, a 6mum-wide stripe type window is made in photo resist formed on the substrate 1, and etched slightly to a depth of about 0.5mum by using ammonia system etching liquid. By a second lithography process, a 4mum-wide stripe type window is made in the photo resist. By using phosphoric acid system etching liquid, a trench about 2mum-deep is formed, which has a shape like an inverted trapezoid. Thus a trench having a two-step inclined surface of different inclination angle is formed. The effective refractive index in the vicinity of the active layer 3 has a distribution wherein the trench form made on the substrate 1 is turned upside down.

Filed: 1988-10-14
Abstract: PURPOSE:To prevent the segregation under the feeding head of a steel casting and to obviate the fracture and cracking of the casting by incorporating a specified amt. of Ca into the molten steel for producing the casting. CONSTITUTION:When the molten steel for a steel casting is charged into a ladle 5 from a steelmaking furnace 6 such as an arc furnace, a wire 4 of Ca-Si is supplied into the molten steel in the ladle 5 by the feeder 1 consisting of a feed roller 3 and a guide pipe 2 to incorporate about 400ppm of Ca, for example, into the molten steel. The molten steel is charged into a casting mold, and a feeding head part is provided at the upper part of the mold to produce a steel casting.

Abstract: PROBLEM TO BE SOLVED: To set up a capacitor in the motor frame of a motor which is driven by using the capacitor, and at the same time, to enable the capacitor to cope with a high-output motor that generates large quantity of heat. SOLUTION: A capacitor 24 is mounted on the capacitor-mounting section 17 of a terminal base set up in a motor frame 2.

Filed: 1986-10-28
Abstract: PURPOSE:To enable long-term suppression of internal shorting due to arborescent precipitation of metallic lithium by adding arsenic, antimony, and phosphorus or bithmuth trihalide to non-aqueous electrolytic solution. CONSTITUTION:At least one kind of arsenic, antimony, and phosphorus or bithmuth trihalide is added to non-aqueous electrolytic solution. Arsenic, antimony, and phosphorus or bithmuth trihalide added to the non-aqueous electrolytic solution are made to react to a solvent composing electrolytic solution and to form a high-molecular film on a lithium negative electrode. Lithium is dissolved and precipitated through this film by charging and discharging, and so arborescent precipitation of metallic lithium is prevented so as to suppress an occurrence of an internal shorting phenomenon. Moreover, the said effect is continued also in a long-term cycle because this film is not subject to oxidation and reduction and it is stable.

Abstract: PURPOSE: To automatically obtain the number of rotations of a motor corresponding to the quantity of dust without requiring the visual observation of dust due to the field manager of a furnace. CONSTITUTION: A CCD camera 1 outputs the video signal of photographed dust to an image processor 2. The image processor 2 forms a digital image having a predetermined number of gradation levels from the video signal and consisting of a plurality of pixels and subsequently calculates the ratio of a pixel having a predetermined gradation level or more to output the same to a sequencer 3.

Upon receiving the number-of-rotation altering command, the inverter 4 forms an AC having a predetermined frequency to output the same to the motor 50 of a dust collector. The motor 50 alters the number of rotations in response to the AC from the inverter 4.

Abstract: PURPOSE:To cut a wafer into individual chips while suppressing the damage to an element caused by chipping occurring at dicing and chipping fragments. CONSTITUTION:When an epitaxial wafer 10 having the chip pattern in which multiple emitting parts (p-type semiconductor regions 13) and electrode parts 14 are arrayed in parallel to a dicing line 22 is cut out into individual chips with a dicing blade 20, an ultraviolet ray curing resin film 30 is formed along the dicing line 22 before dicing.
