Title: Semiconductor device
Inventor: KOJISAWA MASAYA
IPC: H01L27/10
Filed: 1988-02-18
Abstract: PURPOSE:To find addresses simply, by forming symbols by which the addresses of bit line and a word line can be found in a wafer process in a memory cell on a semiconductor wafer. CONSTITUTION:Bit lines 5 are formed in a memory cell part. At the same time a symbol 7 is formed. That is, is the process for forming a semiconductor device, the bit lines 5 are formed by using a photoengraving technology, and the symbol 7 is formed at the same time. For example, the symbol 7 is formed at every fifth bit line. A symbol is also formed in the memory cell by the same way when word lines 6 are formed. The symbol 7 is formed at every fifth bit line, but the symbol can be formed at every arbitrary number of the lines. The numeral that indicates the address can be used instead of the symbol.

Title: Document processing system
Inventor: KUNO SHIGERU
IPC: G06F17/21
Filed: 1989-02-15
Abstract: PURPOSE:To automatize the generation of an index, to reduce the manhour for generating the index and to improve quality by providing an index table storing a character string and a logical number required as the index. CONSTITUTION:The index table 3 which controls a document by the logical number at every assembly of sentences recognized from the start of the character string to a decided terminating code and which stores the character string and the logical number required as the index is provided. Whenever the document is inputted, the document in which the character string is included is registered in the index table 3 with the logical number and the intra-document position of the document string as control information. Then, an index generator 5 for generating the index by control information is provided. Since the document is controlled as the logical number, the logical number as the attribute of the index character string and accompanying information are dynamically controlled at the same time as the input of document data, and index information can be generated. Thus, a defect that the index has to be generated by a manual operation after all the documents are defined is eliminated.

Title: Method for continuous heating of steel strip by vertical type direct heating furnace
Inventor: KOMATSU ATSUSHI
IPC: C21D9/573
Filed: 1995-02-02
Abstract: PURPOSE: To continuously heat a steel strip with a uniform temp. distribution with respect to the transverse direction of this steel strip by suppressing the excessive temp. elevation at the edges of the steel strip which is the defect associated with a vertical type direct heating furnace. CONSTITUTION: The flow rate of the cooling gas of a temp. lower by >=100 deg.C than the steel strip temp. ejected out of cooling gas nozzles or combustion/ cooling burners is controlled in such a manner that the temp. deviation with respect to the transverse direction of the steel strip is kept within a target range by using the vertical type direct heating furnace installed with the cooling gas nozzles or combustion/cooling burners. The control of the combustion rates of the burners in addition to the flow rate control of the cooling gas may be executed as well.  As a result, the excessive temp. rise at the edges of the steel strip is suppressed and the continuous heating of the steel strip with the temp. distribution uniform with respect to the transverse direction of the strip is made possible and the annealed steel sheets and plated steel sheets having the stable product quality are produced.

Abstract: PURPOSE: To set a source-drain interval with high precision while making the parasitic capacity extremely small, by controlling the lateral source-drain expansion and lateral etching of a gate electrode film.  
     CONSTITUTION: An opening is made in SiO 2  thick film 20 of p-type Si substrate 11, n layer 14 is provided, and the exposed surface is covered with SiO 2  thin film 16. Then, p-type poly-Si of W 21 is formed, layers 21 and 16 are etched by resist mask 22, and ions are injected to form n + -layers 12 and 13. Since the gate electrode uses p-type poly-Si or W, a depletion layer produced by the work function difference with n layer 14 cuts off the channel completely. Next, etching electrode 21 laterally  forms gate electrode 18 between layers 12 and 13. After the mask is removed, the  surface is covered with SiO 2 23, an electrode window is formed, and electrodes 17,  19 and 24 are provided. In this way, a process of complex mask matching is omitted and the parasitic resistance of channel 14 is reduced extremely; and the parasitic capacity due to the overlap between the gate electrode, and layers 12 and 13 is made extremely small, so that a miniature and high-speed enhancement MOSFET can be obtained.

IPC: G10K11/16
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To improve safety, facility, durability, weatherability, corrosion resistance, a recycle characteristic and economical efficiency of a sound absorbing material by performing compression molding by sandwiching a material obtained by accumulating belt-like metallic foil such as aluminum by a metallic net-like member. SOLUTION: A belt-like metallic foil sound absorbing material having the whole thickness of about 5 mm is formed by performing compression molding so as to become, for example, bulk density of 0.15 g/cm<3> by arranging/sandwiching a metallic net-like member 3 on/by its both surfaces by covering the surface with sheet-like aluminum foil 2 by accumulating belt-like aluminum foil 1 having, for example, a thickness of 15 μm, a width of 3 mm and the length of about 150 mm. Safety and facility are enhanced since a component and a material do not scatter in the air in a manufacturing process, at installing work time or disrupting time by performing compression molding by accumulating belt-like metallic foil. A metallic net-like member composed of aluminum foil, sheet-like aluminum foil and expanded metal having the same material can enhance strength and durability. This sound absorbing material can be recycled since special chemical work is not required, and a cost can be restrained since the manufacturing process is easy.
