Title: Production apparatus of composite metal sheet
IPC: C04B35/599
Filed: 1992-03-30
Abstract: PURPOSE:To provide thermal crowning weasures for a rolling roll not capable of direct water cooling. CONSTITUTION:In a production apparatus of composite metal sheet by electric heating, the deterioration of sheet shape such as not uniform joining on width direction and center buckling due to the thermal crowning of rolling roll occurs. The problem of the detrioration is solved by a press joining roll made of sintered ceramics. Because of the use of direct electric heating for passing sheet and being unable to direct water spray cooling like hot rolling, the use of the clad roll made of sintered ceramics, having a thermal expansion coefficient smaller than a metal, is indispensable. The structure of the roll can be either one holding ceramic sleeve 41 fitted in the metal shaft 40 or the other of the roll itself made of hollow ceramics.

Title: Micro-heater, its manufacture, and air flow sensor
Inventor: WADO HIROYUKI
IPC: G01F1/68
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide a micro-heater which can be improved in mechanical strength by increasing the thicknesses of a lower thin film and an upper thin film which hold the heat generating layer of a thin film heat generating section between them and, at the same time, to reduce the warping of the whole body of the micro-heater as much as possible. SOLUTION: In a micro-heater, a thin film heat generating section 4 is formed in the form of a bridge laid across a cavity section formed in a silicon substrate. The heat generating section 4 is constituted by successively laminating a lower thin film 6, a heater layer 7, and an upper thin film 8 upon another. Upon the thin films 6 and 8, tensile stress films and compressive stress films are symmetrically laminated with respect to the heater layers 7. The tensile stress films are formed as Si3 N4 films 9 and 12 having high moisture resistances and the compressive stress films are formed as SiO2 films having high adhesibility. Since the tensile and compressive stress films cancel internal stresses each other, internal stresses can be relieved and, since the films also cancel warping moment, the warp of the whole body of the micro-heater can be suppressed.  Therefore, the mechanical strength of the micro-heater can be improved even when the thicknesses of the films are increased.

Title: Aerosol washer
Inventor: MUNAKATA AKIHIKO
IPC: H01L21/304
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent impurities from being restuck to the surface of material to be washed by reducing ruggedness in a buffer chamber, making a washing chamber have such a Laval shape that its width is sufficiently larger than that of the material to be washed, and also directly connecting the buffer chamber and the washing chamber to cause purge gas normally flow from the buffer chamber toward the washing chamber. SOLUTION: Ruggedness in a buffer chamber 190 is made as small as possible, and no gate valve is provided between the buffer chamber 190 and a washing chamber 142. The vertical cross section of the washing chamber 142 has such a Laval shape that it gradually expands from an inlet to the center and it gradually gets narrower from the center to an outlet to straighten aerosol 24, accelerating gas, and purge gas and discharge them. The width of the horizontal cross section of the washing chamber 142 is made sufficiently large compared with the diameter of a wafer 10 to eliminate the influence of the flow and pressure from the sidewall of the washing chamber 142. Purge gas is caused to flow constantly form the buffer chamber 190 toward the washing chamber 142.

Title: Method for manufacturing silicon carbide semiconductor device
Inventor: KOJIMA ATSUSHI
IPC: H01L29/78
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To contrive high mobility in a channel region by a method wherein a large unevenness is not formed in the channel region by a heat process for activating impurities. SOLUTION: A p-type impurity is ion-implanted to a specified region of a surface layer part of an n<-> -type silicon carbide epitaxial layer 2. The p-type impurity is activated by a heat process under the silicon carbide atmosphere to form p--type silicon carbide base regions 3a, 3b having a specified depth. Thus, the heat process for activating the p-type impurity ion-implanted for forming the p<-> -type silicon carbide base regions 3a, 3b is made under the silicon carbide atmosphere, whereby silicon carbide sublimes (evaporates) from a surface of the n<-> -type silicon carbide epitaxial layer 2 and vanishes, and additionally the silicon carbide is supplied onto the surface by subliming (crystal-growing). Therefore, the n<-> -type silicon carbide epitaxial layer 2 can be formed so as not to form large unevenness.  Therefore, it is possible to make efficient a surface channel layer 5 formed on a surface of this n<-> -type silicon carbide epitaxial layer 2.

Subsequently, the above-mentioned aqueous solution is gradually cooled, and at a temperature of 50°C or lower, basic chromium formate is crystallized to be separated by filtration and recovered. It is preferable that the concentration of chromium matter is 3% or more as Cr 2 O 3  in the above-mentioned aqueous solution. As a result, 80W90% Cr in chromium-containing sludge can be recovered through a simple process.

Abstract: PURPOSE:To make smaller the capacity of an ROM necessary for a signal processing by forming a signal to correct the change of a color reproductivity with a color temperature, changing a coefficient for a chrominance signal modulation by it and obtaining a modulating chrominance signal correcting the color reproductivity. CONSTITUTION:A multi-phase modulation system is used as a means to obtain the modulating chrominance signal of an NTSC, etc., with a digital processing. A coefficient for this purpose is generated from an ROM 10 and the modulation chrominance signal for the NTSC, etc., and a high speed successive color difference correction signal to be outputted from an ROM 7 through a selector 8 are multiplied by a multiplier 9. Further, when the output and the high speed sequential color difference signal of the output (A) of one horizontal scanning period delaying line are modulate-processed by a multiplier 2, latches 3 and 4 and an adder 5, the modulating chrominance signal (NTSC signal) correcting the change of the color reproductivity by the color temperature is obtained. Thus, the ROM of a small capacity is enough as the ROM for the color reproduction correction.

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of electric characteristics of MOSFET by a method wherein there is formed a structure in which the width of an insulation material buried in an isolation groove of a semiconductor substrate is narrower than that of the insulation material projected from the isolation groove. SOLUTION: A side wall 14 of a width 15 is provided on a side face of an opening part. Namely, after a thermal oxide film 3 is deposited on the entire face of the opening part, the side wall 14 is formed by etching-back. Here, the shape of the side wall 14 after etching back has a curvature. Next, by using a silicon nitride film 2 and the side wall 14 as a mask, a silicon substrate 4 is selectively etched to form an isolation groove 5. Next, a thermal oxide film 6 is formed in an inner wall of the isolation groove 5 by thermal oxidization. At this time, if a thickness 16 of the thermal oxide film 6 is set smaller than the width 15 of the side wall 14, both regions isolated do not invade MOSFET.  Accordingly, both actual isolated regions are above the silicon substrate 4, and in other words are an isolation width 1 designed initially, so that deterioration of electric characteristics of the MOSFET is eliminated.
