Title: Air blowing device using double-acting air cylinder
Inventor: NEO SUMIO
IPC: B23Q11/00
Filed: 1994-10-18
Abstract: PURPOSE: To heighten the exhaust pressure of a double-acting cylinder so as to be able to use the exhaust air as air blow by connecting an air blowing pipeline to the exhaust side of the double-acting cylinder, and providing a shock absorber, actuated in the vicinity of both ends of the travel of the double-acting cylinder, on the driven body side. CONSTITUTION: The collars 7, 8 of a shock absorber 10 are spaced, and a movable cylinder 12 moves rapidly without the action of the shock absorber 10 until reaching the vicinity of the ascent end. Exhaust air exhausted from a lower chamber 12b is thereby blown off from the tip of an air blowing circuit 20 while keeping sufficient exhaust pressure to clean a desired place. When the movable cylinder 12 reaches the vicinity of the ascent end, the collar 7 of a rod 6 comes in contact with the upper face of an arm 5 to actuate the shock absorber 10, and a driving shaft 13 is slowly stopped, so that there is no fear of displacement and falling of a piston supported on the upper end.

Title: Catalytic combustion type fluid-heating apparatus
Inventor: KAYAHARA TOSHIHIRO
IPC: F23C99/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent burnout or fusion of a catalyst due to overheating so as to maintain combustion in a stabilized state and lower the emission of CO in the exhaust gas from the combustion even in the case of a mixed gas with a low air ratio by alternately arranging in a combustion heattransfer part in a gas-passageway a catalyst part and a heat-transfer part in the direction of the flow of the mixed gas. SOLUTION: A catalyst part 11 in a combustion heat-transfer part 10 is preheated and when the temperature has risen to a point that enabls the start of catalytic reaction, the supply of mixed gas 4 to a gas passageway 2 is started. Since the catalyst part 11 has already been preheated to a temperature that enables catalytic combustion, the arrival of the mixed gas 4 instantly causes the combustion reaction to start. Through catalytic combustion the mixed gas 4 becomes a high-temperature gas as it flows past the catalyst part 11 and flows into a heat-transfer part 14 in the following step. Since in this heat-transfer part 14 the high-temperature heat of the mixed gas 4 is transferred to a fluid to be heated 7 in a fluid channel 1, the temperature of the mixed gas 4 rapidly falls.  This fall of temperature sufficiently allows to start catalytic reaction when mixed gas 4 flows into the next catalytic part 11.
