Title: Repairing method for concrete construction
Inventor: ITOU YOSHIKAZU
IPC: E04G23/02
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To easily peel an old coating film without personal assistance by applying a form oil composition composed of an alkaline compound consisting of a compound having a specified weight% of composition, thickener and solvent to the surface of a concrete construction, and installing a sheet on it, and then peeling it. SOLUTION: An alkali metal compound is used at 1-50weight% on the total weight% of the alkali metal compound and an alkaline earth metal compound, and consequently the alkaline earth metal compound is used at 99-50weight% on the above total weight%. The proper thickener and the solvent are used for the alkaline compound composed of both the above compounds at each fixed weight% on the weight of a form oil composition, and in the case of need, a proper optional additive is blended. When this release agent composition is applied to a coating film existing on the concrete construction surface, the form oil composition decomposes, swells and then peels the coating films, and the lower applied film having decomposed is therefore simultaneously peeled.

Title: Cathode for molten carbonate fuel cell
Inventor: SOTOIKE YOSHIAKI
IPC: H01M4/86
Filed: 1988-03-15
Abstract: PURPOSE:To decrease the internal resistance of a cathode, to decrease voltage drop in a cell and to increase cell performance by folding the extended parts on both sides of reinforcer comprising a metal mesh or punched metal arranged inside a sinter mainly comprising nickel oxide on the cathode gas supply side to form a current collector. CONSTITUTION:A cathode 1 consists of a sinter mainly comprising nickel oxide and a reinforcer 2 comprising a metal mesh or punched metal arranged inside the sinter. The extended parts on both sides of the reinforcer 2 are folded on the cathode gas supply side to form a current collector 3. Since the metal reinforcer 2 and the current collector 3 are formed in one body, the contact resistance between the cathode 1 and the current collector is eliminated, and electrons from an outside load are directly conducted to the reinforcer in the cathode and distance to reaction site is shortened. The internal resistance of the cathode is decreased and voltage drop in a cell is also decreased. The performance of the cell formed by stacking many unit cells is especially improved.

Further, in the fourth step, the water-washed galvanized steel plate ZnS or stainless steel plate ST is heated and a fluorine resin film Ff is deposited on the plate. Next, the film is heated at a temperature of about 34 deg.C from the surface to be molten. Consequently the fluorine resin film Ff seeps into the acute-angled rough surface of the galvanized steel plate ZnSt or the stainless steel ST. Then the plate is cooled down to 100 deg.C and in the fifth step, the molten fluorine resin film Ff is baked at about 320 deg.C for about 10 minutes. Finally in the sixth step, the plate is shaped as desired.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To suppress decrease of on-current by specifying the peak angle of a protrusion on a rough surface present at the interface between a semiconductor film and a gate insulating film to be at least a right angle, or specifying width and height of the protrusion on the rough surface. SOLUTION: The thin-film transistor comprises a semiconductor film 2 and a gate electrode 4 with a gate insulating film 3 between them. Here, an apex angle A of the protrusion of a rough surface 8 present at the interface between the semiconductor film 2 and the gate insulating film 3 satisfies A>90 deg.. Otherwise, a width W and height H of the protrusion of the rough surface 8 satisfy an equation: (W/2)H>tan(90 deg./2). Since the shape of the rough surface 8 does not prevent conduction of carrier, drop of on-current is suppressed.

Filed: 1984-03-29
Abstract: PURPOSE:To prevent deterioration of image density and fixability of a toner image to a transfer paper, and to enhance fluidity and storage stability by adding hydrophobic silica and carbon black to the outsides of toner particles in a proper amt. CONSTITUTION:The toner powder used here has a particle diameter distribution of <=30mum and contains carbon black in the inside of the particles in an amt. of 3-20wt%.

Title: Detecting circuit of power supply voltage
Inventor: TSUJIMOTO JUNICHI
IPC: G06F1/00
Filed: 1985-03-28
Abstract: PURPOSE:To attain the stable detection of the power supply voltage regardless of the variance of the transistor characteristics, by using a p channel MOS transistor for pull-up and an n channel MOS transistor for pull-down. CONSTITUTION:The difference between the voltage of a fixed level supplied to the gate of a transistor TR22 and the power supply voltage VDD is larger than the threshold value Vth of the TR22 with increase of the voltage VDD. Thus the TR22 is turned on and therefore the voltage 43 of a detecting signal output terminal 21 is suddenly changed to a level close to the VDD from the standard power supply voltage VSS. Then the output signal of an inverter 24 is suddenly inverted and then the voltage 44 of an output terminal 26 of the following inverter 25 is also changed suddenly. Here the voltage 43 of the terminal 21 is changed suddenly to a level close to the VDD from the VSS. This can eliminate the variation of the detected voltage owing to the change of characteristics at a level close to the threshold voltage of a conventional inverter circuit.
