Title: Method for drying coated body
Inventor: KATSUTA HIDEO
IPC: B05D3/04
Filed: 1988-03-25
Abstract: PURPOSE:To uniformly heat a coated body by rotating the body around a horizontal axis in a drying furnace provided with a heating source at the upper part. CONSTITUTION:Far IR radiating panels 11 as a heating source are arranged on the surface of the upper wall of a drying furnace 10.

A body W can be uniformly heated by rotating the body W around a horizontal axis to the fixed heating source 11. The direction of gravity acting on paint is varied, so the smoothness of the coated surface can be increased by utilizing the flowability of the paint.

IPC: C21C7/00
Filed: 1986-03-28
Abstract: PURPOSE:To thoroughly remove fine inclusions as well and to produce a high Cr steel having excellent cleanliness by refining the high Cr steel under specific operating conditions in a secondary refining furnace using refractories contg. MgO at a low ratio at the time of producing a clean steel by secondary refining of the high Cr steel. CONSTITUTION:A stainless steel such as ferritic or austenitic stainless steel contg. 0.5-35wt% Cr as precision electronic parts is required to have the cleanliness and therefore, the refractories contg. <=10% MgO are used to make reduction refining by adjusting the basicity of the slag to 1-2 and to incorporate at least one kind of 0.05-2% Si in the molten steel and 0.01-1.0% Al in the range of Si+Al<=2% into the steel throughout the entire refining period at <=1,700 deg.C at the time of secondary refining. The elution of MgO from the refractories of the furnace is low and even if MgO exists therein, the MgO is reduced to Mg by Si and Al or is easily adsorbed into the low basicity slag. The fine nonmetallic inclusions, sized <=10mu, by the existence of the MgO are easily removed and the Cr steel having the high cleanliness is obtd.

Title: Fuel cell, separator for fuel cell, and manufacture thereof
Inventor: TASHIRO AKITSUGU
IPC: H01M8/10
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a separator, causing no problems in characteristics such as electrical resistance, gas permeability, liquid swelling properties, and mechanical strength, and satisfactory in moldability, by thermoforming a mixture including a phenol resin to be ring-openingly polymerized by reaction with a carbon material. SOLUTION: A separator for a solid high-polymer fuel cell is manufactured by thermoforming a mixture including a phenol resin to be ring-openingly polymerized by reaction with a carbon material. Preferably, powder of expanded graphite is used as the carbon material. As the expanded graphite, expanded graphite having worm-like shapes and compression characteristics, can be obtained, for example, by immersing graphite in a solution with an acid constituent, thereby producing a graphite interlayer compound, rinsing the graphite, and then rapidly heating it so as to cause graphite crystals to extend in the C axis direction. As the phenol resin cured by ring-opening polymerization, a resin including a dihydrobenzoxazine ring is preferable because of its excellent moldability and heat resistance.  This resin, when heated, produces a ring-opening polymerization reaction, without using any catalyst or curing agent, and without generating any volatile matter.

IPC: E04G23/08
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To interrupt an automatic operation regardless of operating quantity and keep the stopped state after the operation is released by outputting a switching signal to an automatic control valve according to the signal from a crushing operation sensor when an automatic operation start command is inputted, and stopping this signal when a pedal is operated in operation. SOLUTION: When the automatic operation start command from a start switch 25 is inputted to a controller 19, the expanding and contracting operation of a crushing cylinder 12 is controlled through an automatic control valve 16 by the controller 19 on the basis of the signals from crushing operation sensors 20, 21. When a pedal is operated in automatic operation, the signal output from the controller 19 to the automatic control valve 16 is stopped on the basis of the signal from a pedal operation sensor 23. The automatic operation is thus stopped, and transferred to the manual operation by the pedal. Thus, the movement of a crushing machine 11 unexpected by an operator just after the release of pedal operation can be eliminated.

Abstract: PURPOSE:To enable high speed measurement with high resolving power, by using a clock signal not related to measuring timing and a triangular wave synchronous to said signal. CONSTITUTION:The clock outputted from an oscillator 301 through an AND gate 304 closed by an input signal 101 to be measured is counted by a count means 305. The frequency of the clock from the oscillator 301 is divided by FF302 to generate a triangular wave synchronous to the clock from a triangular wave count circuit 303 and said triangular wave is held to the sample holding circuit 306a controlled by the timing signal generating circuit 102 responding to the signal 101. The holding value of the circuit 306a corresponding to the clock non-count period of the signal 101 is supplied to an operation means 309, to which the count output of the means 305 is also supplied, through an A/D converter 308a. The non-count period of a signal terminal is processed similarly and the time of a signal period is measured at a high speed with high resolving power using the clock not related to measuring timing and the triangular wave.
