Inventor: OKAMURA TATSUROU
IPC: B29C44/56
Filed: 1982-09-28
Abstract: PURPOSE:To obtain the titled apparatus that can mold precisely corrugated sheets, by positioning feeding plates spaced a little after heating wires that will be traveled in an undulating manner so that when the traveling speed of the heating wires is lowered, the feeding amount of the heating wire is increased. CONSTITUTION:The feeding plates 5 are positioned with a space (t) after the heating wires 3, and the heating wires 3 are traveled in an undulating manner so that the foamed resin body 20 is melted and cut into corrugated sheets. When the heating wires 3 encounters harder part of the foamed resin body 20, the heating wires 3 are displaced backward as shown by dotted line to be engaged with the feeding plates 5 and are fed with an electric current through the feeding plates 5, so that the amount of generated heat is increased to increase the cutting force and therefore the strain would not be caused in the obtained corrugated sheets.

Title: Activated carbon for deodorization and removal of offensive odor component
Inventor: AIBE NORIO
IPC: B01J20/20
Filed: 1980-12-05
Abstract: PURPOSE: To obtain an activated carbon capable of deodorizing gases containing S compounds and N compounds as offensive odor components at one time, which supports Br 2  and inert acids.  
     CONSTITUTION: A raw material, e.g., char coal, coke etc., is activated by a well- known method of prepare an activated carbon having a surface area of 200W 2,000m 2 /g. The activated carbon is dipped in an aqueous solution of an inert acid, e.g., sulfuric acid, oxalic acid, etc., kept at 50°C and a vapor pressure of 10mm or less and then dried. In this case, the amount of the acid used is 1W 35wt% on the basis of the activated carbon. Then, a carrier gas containing Br 2  gas, for example, is brought into contact with the activated carbon so treated to support Rr 2  on the activated carbon. The activated carbon thus obtained has a very high effective deodorizing capability for gases containing S compounds, e.g., H 2 S, mercaptan, etc., and N compounds, e.g., NH 3 , amines, etc., as offensively odorous components.

Title: Infrared ray detecting element
Inventor: HIROTA MASAKI
IPC: H02N11/00
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To minimize the dispersion in sensitivity to positional fluctuation of a membrane end part, and increase its strength by forming the connecting part of a cold contact part with a thermocouple member long, and making it into a layered structure with a wiring layer. SOLUTION: The contact hole of the cold contact 14 part of a thermopile, or the connecting part is formed long, and made into a two-layer structure consisting of a p-type polysilicon 6 or n-type polysilicon 7 and an aluminum film which is a wiring layer. The two-layer structure part formed long is constituted so as to straddle a membrane end part 15, whereby the thermal resistance of this part is smaller than that in the part of the other thermopile part. Therefore, the temperature gradient of the contact 14 part is moderated. Thus, even when the position of the end part 15 formed by wet etching (anisotropic etching) difficult to minutely control is fluctuated, the fluctuation of thermal resistance of the thermopile is minimized to extremely minimize the dispersion in sensitivity. This structure increases the strength of the end part 15 where mechanical stresses are collected.

Filed: 1991-07-12
Abstract: PURPOSE:To form a fine element isolation wherein a crystal defect is small to be adapted to high integration of a semiconductor integrated circuit. CONSTITUTION:A silicon nitride film 12 which has been deposited in 160nm is removed selectively by a photolithographic technique and a dry etching technique; a filed oxide film 13 which has been buried deep in a semiconductor silicon substrate is formed to be a thickness of 600nm by a thermal oxidation operation (c).

Thereby, the field oxide film 13 and the silicon substrate 11 are etched down to a depth of 150nm (e). Consequently, the creeping of a bird's beak can be reduced as compared with that by a LOCOS method in conventional cases, a crystal defect is reduced because a silicon crystal near the bird's beak is etched, and a fine element isolation can be formed.

Abstract: PROBLEM TO BE SOLVED: To provide grinding mode identification technology which highly accurately measure and evaluate the grinding mode of a surface to be ground with non contact by identifying the grind mode of a surface to be measured from the angle formed by the normal direction and the grinding direction of the surface to be measured. SOLUTION: When a grinding surface of a hard and brittle material which is worked by changing the cut depth of a grinding wheel is observed by a scanning electron microscope, a ductile mode grinding surface, a brittle mode grinding surface, and a mixed surface having both modes mixed therein are observed.  Then, the grinding surface is divided into a lot of micro-surfaces of 1μm or less and the inclination of the micro-divided faces is expressed by a normal vector, so that all the micro-divided faces on the grinding surface are observed as shown in a figure by setting the angle formed by crossing the normal of the grinding surface and the normal vector of the micro-divided faces with each other as the inclination of the normal, and setting the angle of the normal vector in the case of projecting the normal vector of the micro-divided faces on the grinding surface as the direction of the slope. Then, there is a difference between the ductile and brittle modes in the angle formed by the inclination or the direction of the normal and the grinding direction so that the grinding mode can be identified by using this difference.

Filed: 1990-06-30
Abstract: PURPOSE:To improve a characteristic and to enhance a production yield by a method wherein this transistor is constituted of the following: a first recess, having a small width, which is formed in a compound semiconductor substrate; a second recess which is formed in this region so as to be shallower and larger in width than the first recess; and a gate electrode. CONSTITUTION:A source resistance Rs is decided approximately by the width size of a first recess 4; and a gate breakdown strength and a Cgd are decided apporximately by the width size of a second recess 5. As a result, the width sizes of the first and second recesses 4, 5 with reference to the Rs, the gate breakdown strength and the Cgd can respectively arbitrarily be set. While the Rs is reduced, the gate breakdown strength can be enhanced and the Cgd can be reduced. When a characteristic is deteriorated by the damage and the contamination at an etching operation to form the first recess 4 by using a dry etching operation, the damage and the contamination can be eliminated by a wet etching operation to form the second recess 5. As a result, it is possible to almost disregard the influence on the characteristic by the dry etching operation.
