Title: Semiconductor laser
Inventor: MATSUOKA TAKASHI
IPC: H01S5/00
Filed: 1987-11-20
Abstract: PURPOSE:To obtain a high efficiency, a high output and a high speed modulation characteristic and to obtain a semiconductor laser having an easy manufacturing process and high yield production by burying a buried region of a side face parallel to the light propagating direction of a stripelike active region with a semi-insulating group II-VI compound material. CONSTITUTION:A current is injected from a metal electrode 8 to arrive at a metal electrode 9. In this case, the current is narrowed by an insulating diffusion stopping layer 6 and a buried layer 7, and injected only to an active layer 3. Since the layers 6, 7 are formed of a material having lower equivalent refractive index when a semiconductor substrate 1, a clad layer 2, an active layer 3, a clad layer 4 and a cap layer 5 are regarded as being one layer, the light can be enclosed in the layer 3. Further, since the layers 6, 7 are transparent, the light oozed from the layer 3 to the layers 6, 7 is not absorbed. Further, since the layers 6, 7 between the electrodes 8 and 9 do not have a junction in an elevational direction, no electric capacity is provided, and a high efficiency, a high output, a low threshold and a high speed modulation are performed.

Title: Manufacture of raw material oil for carbon black
Inventor: UCHIDA MASARU
IPC: C10C3/00
Filed: 1991-10-14
Abstract: PURPOSE:To simply and easily obtain a high-quality raw material oil for carbon black by subjecting a mixture of a tar-base heavy oil and a tar pitch to centrifugal separation to remove the precipitate therefrom so as to reduce the quinoline- insolubles content below a specified value. CONSTITUTION:A by-product heavy oil in the manufacture of pitch coke or a heavy oil obtained by the fractional distillation of coal tar is mixed with a tar pitch comprising a distillation residue of coal tar at a weight ratio of (1:9) to (9:1) to give a composition having a quinoline-insolubles content of 0.2wt.% or higher. This composition is subjected to centrifugal separation to remove the precipitate therefrom and recover a hydrocarbon material having a quinoline-insolubles content of 0.1wt.% or less, thus giving an objective raw material oil. Examples of the heavy oil to be used include creosote oil and anthracene oil; those oils which are usually used alone as the raw material for carbon black can be used.

Abstract: PURPOSE: To form a small R having uniform dimensions stably in the vicinity of a position where a fastener touches a chuck by making a groove on the rear surface side at the R of the fastener by means of a protrusion provided on a die. CONSTITUTION: A protrusion 3 on a die 4 has dimensions being set such that it abuts against the root at a flange part 6 on the rear at the R part 2 of a fastener 1. A circumferential groove 9 is made at the root of the flange part 6 on the outer surface of the fastener 1 by the protrusion 3 on the die 4. Consequently, the R part 2 is inflated to the surface side by an amount corresponding to the volume of the groove 9. Since the inner surface part of the fastener 1 is defined by the outer surface at the tapered protrusion 5 of a punch 8 and the surface at the flange part 6 of the fastener 1 is defined by the flat part 7 of the punch 8, these parts are not inflated. Consequently, the outline at the R part 2 of the fastener 1 is inflated outward and the radius of curvature is reduced at the R part 2.
