Title: Production of l-amino acid containing sulfur
Inventor: HATAMOTO OSAMU
IPC: C12N9/10
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To simply produce an L-amino acid containing sulfur from L-serine in high yield as compared with a conventional method. SOLUTION: An L-amino acid containing sulfur is produced by reacting (A) L-serine with (B) a sulfide, (C) an acetyl-CoA, (D) acetyl phosphate and (K) a microbial cell of a microorganism transformed with a recombinant DNA prepared by integrating DNAs respectively coding for a serine acetyltrasferase(SAT), a phosphotransacetylase(PTA) and an O-acetylserine-lyase(OASL) into a vector DNA and/or its treated substance. Since the reaction is carried out in the presence of the PTA and acetyl phosphate, the L-amino acid containing sulfur can be produced at a low cost without requiring the addition of a large amount of the acetyl-CoA thereto.

IPC: H01L27/112
Filed: 1986-07-17
Abstract: PURPOSE:To decrease the time required for overall processes by a method wherein the formation of ROM patterns and the formation of interconnection patterns are performed by the same photoetching process. CONSTITUTION:A field oxide film 2, a source-drain region 8, a channel region 4, a gate insulating film 5 and a gate electrode 6 are formed on a P type substrate 1. Next, a protective insulating layer 7 is formed and then a contact holes 8 are made in the positions corresponding to overall region of layer 7 to form a conductive layer 10 thereon. Thus, overall region 3 is commonly connected to the layer 10 Later, when any data to be written are presented by a user, ROM patterns are designed conforming to the data to decide if any MOSFET elements on an array are necessary or not. The overall region 3 being connected to the layer 10, this shortcircuited state may be maintained for any unnecessary elements while the layer 10 may be removed to isolate the source-drain from each other for any necessary elements. Through these procedures, the time required from receiving order to delivery can be cut down.

Title: Headstock structure
Inventor: YAMAWAKI HIROSHI
IPC: B23Q1/72
Filed: 1990-06-27
Abstract: PURPOSE:To set the thermal displacement direction of a headstock close to the direction in which the working precision is given with the least influence, by installing a means for elongating or shortening a heat transfer passage on the correction side or opposite side of the thermal displacement direction of the headstock, on the headstock of a lathe. CONSTITUTION:As for a lathe, a slant head is fixed on the rear side on the upper surface of a leg installed on a floor, and a headstock 6 is fixed on the left side on this side on the leg, and a main spindle 7 is bearing-supported in turnable manner on the headstock 6. On the headstock 6, a plurality of holes 6a-6d are formed on this side of the vertical plane passing through the main spindle axis center, and the heat transfer to a surface part 6e on this side from a bearing part is carried out through a rib between the holes 6a-6d, and the heat transfer distance is prolonged. Accordingly, when the main spindle 7 is revolved, the temperature of the main spindle 6 rises gradually by the heat generation at the bearing part. When the heat generation quantity is constant, the heat radiation quantity and the heat generation quantity are balanced after the lapse of a certain time, and the temperature of the headstock 6 is stabilized. The temperature of the front side part 6e is kept at a low temperature by the effects of the holes 6a-6d.

Title: Production of optical waveguide
Inventor: HIROSE CHIZAI
IPC: C03B19/14
Filed: 1993-07-08
Abstract: PURPOSE:To suppress an increase in propagation loss by suppressing the generation of heterogeneity in a vitrified film. CONSTITUTION:This process for production of the optical waveguide consists in forming the optical waveguide having a core 132 essentially consisting of quartz and a clad layer 122 enclosing this core by deposition of a glass particulate layer 140 by a flame deposition method and formation of the transparent glass particulate layer 142.

Title: Deoxidation of molten steel in oxygen steel-making furnace by aluminum wire injection
Inventor: KITAGAWA MASAKI
IPC: C21C7/04
Filed: 1979-12-26
Abstract: PURPOSE: To ensure deoxidation of molten steel with enhanced Al yield and free from anticipation of phosphorus return by forcibly adding a specified amount of Al wire into molten steel in furnace after the end of blowing.  
     CONSTITUTION: After the end of blowing in converter steel making, the furnace body of the converter 1 is tilted to measure the temperature in the molten steel 2 and to sample from the furnace, then an Al wire 4' is charged from the furnace inlet into molten steel 2. In more detail, a feeder 5 is used to supply Al wire 4' from Al-wire drum into the furnace 1 via guide pipe 6 so that the Al wire passes through slag layer 3 into the molten steel 2 to cause deoxidation in the furnace. This Al-wire infurnace deoxidation contributes to a high-yield and stable deoxidation process, and eliminates adverse effects due to phoshporus return, thereby providing a clean steel having less oxygen content.
