Title: Smelting method for dead soft, extra-low nitrogen high chromium steel
Inventor: NOMURA HIROSHI
IPC: C21C7/10
Filed: 1989-11-10
Abstract: PURPOSE:To obtain a dead soft, extra-low nitrogen high Cr steel in a shortened refining time with high productivity by successively subjecting Cr-contg. molten pig iron to rough decarburization in a converter, decarburization in vacuum and denitrification with Al, removing the remaining Al and regulating the compsn. CONSTITUTION:Cr-contg. molten pig iron is rough-decarburized to 0.03-0.15 wt.% C with a converter having function to blow gas from a position under the surface of the bath. The molten pig iron is further decarburized to <=60ppm C with a vacuum degassing and refining apparatus provided with a ladle and >=2% Al or Ti is added to denitrify the molten pig iron to <=80ppm N. The remaining Al or Ti is oxidized with gaseous or solid oxygen in vacuum until the desired residual content is attained and the resulting product is floated and removed. The compsn. is then regulated. Secondary refining time can be shortened and productivity is enhanced.

IPC: E04B1/86
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To efficiently absorb noises even if there are many noise sources and noises of different frequency level are generated. SOLUTION: The sound absorbing material 1 is fitted onto the surface of a hood panel P on the side of an engine room, and this sound absorbing material 1 has a felt layer 2 and a resonance layer 3 which is provided covering the felt layer 2. The felt layer 2 is arranged nearby a noise generation source (lower side in figure) and the resonance layer 3 is arranged at a distance from the noise generation source (upper side in figure). The resonance layer 3 consists of a bored plate 5 having many holes 5a provided at constant intervals and an air layer 6 provided behind it. The felt layer 2 mainly absorbs noises in a high-frequency range. Further, the resonance layer 3 mainly absorbs noises of a relatively low frequency range.  In this case, the felt layer 2 is arranged closer to the noise generation source than the resonance layer 3, so the trouble that noises are reflected by the bored plate is eliminated and the noises can efficiently be absorbed.

Title: Semiconductor photodetective device
Inventor: YAMAGUCHI MASAKI
IPC: H01L31/107
Filed: 1989-11-09
Abstract: PURPOSE:To diffract an incident light vertical to the incident direction so as to elongate a light absorbing layer in absorption length and to improve a semiconductor photodetective device not only in quantum efficiency but also response speed by a method wherein an echelette diffraction grating is formed in the light absorbing layer. CONSTITUTION:When light is made to be incident on a semiconductor photodetective device from above, it penetrates through a P<+> region 9 and an N-InP layer 6 without being absorbed by them. As a reverse bias is applied between an N-side electrode 12 and a P-side electrode 11, an N<->-InGaAs light absorbing layer 3 is made depleted, and electron pairs and hole pairs are photo-generated by the incident light in the layer 3 and travel toward the N-side electrode and the P-side electrode respectively. The incident light is diffracted in a direction parallel to the deposition plane of the light absorbing layer 3 by an echelette diffraction grating 4, whereby the absorbing layer 3 can be made large enough in absorption length lessening electrons and holes in traveling time by the reduction of the layer 3 in light incident area. A primary maximum which usually appears at a zero order is transferred to a high order, whereby an angle which are laminated plane forms with the plane where the echelette diffraction grating is provided can be made small and the layer 3 can be made large in light receiving area, and a fiber cable and a photodetective device can be optically coupled with ease.

Title: Manufacture of semiconductor device provided with contact part
Inventor: HIGUCHI KOICHI
IPC: H01L21/3065
Filed: 1987-11-20
Abstract: PURPOSE:To prevent any denatured matter of a photoresist at a through-hole part from being produced together with prevention of breakage of any wiring by etching an insulating film in parallel to at least a partial interval of a process of making an opening through the through-hole part, and making an opening through a dummy region which has not been completed at the time said opening through the through-hole has completely been made. CONSTITUTION:Holes corresponding to both of a hole part 15 and a dummy region 17 are patterned on a photoresist film 14 on a plasma silicon nitride film 13 only by a single development process, and the through-hole part 15 and the dummy region 17 are etched at the same time. Hereby, the through-hole part 15 is completely opened to expose the surface of a first layer aluminum wiring 12 to the outside. Thereupon, in the dummy region 17, after the silicon nitride film 13 has completely been opened, etching for an insulating film in a substrate 11 located as a lower layer of the silicon nitride film 13 proceeds. For this, no denatured matter of the photoresist is sticked to the through-hole part 15. Thus, any breakage of an upper layer wiring (second layer aluminum wiring 18) can be prevented.

Title: Thin film forming device
Inventor: OTA WASABURO
IPC: C23C14/32
Filed: 1989-11-10
Abstract: PURPOSE:To form the thin films of various kinds of compds. with excellent adhesive strength even on a substrate having small heat resistance by ionizing the particles of a material to be evaporated and an active gas by thermions in a vacuum chamber and accelerating the ions by a grid, thereby bringing the ions into collision against the substrate surface. CONSTITUTION:A crucible 8 consisting of a conductive metal, such as W or Mo is placed in a vacuum chamber 1 and a metal for vapor deposition, such as, for example, Al, is put therein and is energized by a power source 20. The crucible 8 is heated to a high temp. to melt and evaporate the Al therein. The evaporated Al particles are heated to a high temp. by a power source 21 and are ionized by the thermions generated from a meshed W filament 7. The ions are accelerated by a net-like grid 6 impressed with a more positive voltage than the filament 7 by a power source 22 and the vacuum chamber 1, by which the ions are brought into collision at a high speed against the substrate 100 mounted to a counter electrode 5. On the other hand, a gaseous mixture composed of an active gas, such as O2, and an inert gas, such as Ar, introduced from a pipe 4 is ionized as well and the ions thereof are collide against the substrate 100 to react with the Al. The thin film of A12O3 is thus formed with the high adhesive strength. The material to be evaporated is ionized and has electrically high energy; therefore, the excellent thin film of the compd. is formed at the low temp. even if the substrate 100 has the small heat resistance.
