IPC: B41J35/20
Filed: 1988-03-23
Abstract: PURPOSE:To facilitate assemblage and adjustment and stabilize printing quality, by oscillating a holder provided on a frame through a drive-transmitting part member until a locking member makes contact with a fixed pert, thereby detecting the position of an original point. CONSTITUTION:With a power supply switched ON, a motor 10 is supplied with a predetermined number of pulses to be rotated in the direction of an arrow A, whereby a large gear 30 engaged with a pinion 12 is rotated in a counter arrow direction, and a ribbon cassette holder 2 is oscillated on a support shaft 6 in the direction of the arrow A. A locking part 32 is also rotated to collide against a fixed part 36. The collision causes step-out of a stepping motor 10, and 8 specified exciting phase of the motor 10 is excited after inputting of a predetermined number of pulses is finished. The motor 10 is rotated in the direction opposite to the arrow A, is stopped at a stable position, and is maintained at the position by a static torque. This position is the position of an original point, and a predetermined gap C1 is generated between the locking part 32 and the fixed part 36. Thus, the gap C1 can be set to a large value, assemblage and adjustment are facilitated, and printing quality is stabilized.

Abstract: PURPOSE:To achieve a stable combustion of coals at a high efficiency by a method  wherein a carbonaceous material is converted ino a vaporized fuel, the resultant by- product solid carbon residue is subjected to fluidized combustion to produce oxygen  for combustion, and the fuel and the oxygen thus produced are mixed and burnt. CONSTITUTION:A carbonaceous material is supplied by a feeder 2 into a furnace 1 and is gasified by a gasifying agent flown therein from the bottom of the furnace  while it makes swirling motion so as to produce a combustible gas. Then, cyclone dust  containing unburned carbon component is separated in a cyclone 4 and is fed as a fuel gas through a flow path 13 into a combustion chamber 18. The cyclone dust is supplied  by a feeder 8 into a fluidized combustion furnace 7 and is then subjected to fluidized  combustion at the bottom 10 of the furnace by the secondary and tertiary airs 11 and  the resultant heat preheats a large amount of excess air. The ash content in the resultant high temp. preheating air containing the exhaust gas generated by the combustion is separated by a cyclone 14 and at the same time the unburned ash content is  burnt or removed by the action of the cyclone burner. Subsequently, the preheating air  free of ash is introduced into the combustion chamber 18 so as to burn the aforementioned fuel gas fed from the gasifying furnace 1.

Abstract: PURPOSE:To reduce the power loss of an engine at temperature control by separately controlling the temperature of the upper blow off air using an electric control means for controlling the evaporator cooling performance and the temperature of the lower blowoff air using a temperature control damper that controls the hot to cool air ratio. CONSTITUTION:The air sent from an air blower 13 is blown from only an upper blowoff port 14 at cooling since a damper 19 from a first air path 17 is closed. When the temperature control section is set between the maximum cooling position and the maximum heating position, the preset temperature of an evaporator 12 is controlled through a thermostat 26a and a temperature control damper 43 is opened and closed. Thus, the cool air is blown only the upper blowoff port 14 and cooling is obtained. At heating, the first to third dampers 19, 21, and 24 are opened separately and the cool air and the hot air allow the air flow ratio to be controlled by the temperature control damper 43 and are blown from a lower blowoff port 22. As a result, the waste of engine power can be prevented by performing the upper blowoff temperature depending upon the cooling performance control of the evaporator.
