Title: Linearly reciprocating cylinder device
Inventor: SAIDA YOUICHI
IPC: F15B15/14
Filed: 1980-05-20
Abstract: PURPOSE: To make the device small-sized and light in weight by providing a free piston inside a cylinder employed in structure of a power-driven artificial leg and the like, constituting a gas chamber between a piston rod and the free piston and thereby unnecessitating an accumulating chamber.  
     CONSTITUTION: Inside the cylinder 1 a piston 4 having the piston rod 5 projecting outside through a rod guide 2 and the free piston 6 are provided slidably in the directions of arrows A and B. Furthermore, an oil chamber 7 is formed between the rod guide 2 and the piston 4, the gas chamber 8 wherein high-pressure gas is enclosed is formed between the piston 4 and the free piston 6, and another oil chamber 9 is formed between the free piston 6 and a bottom plate 3. When pressure oil flows into the oil chamber 9 by operation of a switching valve 18, the free piston 6 moves in the direction of the arrow A and contracts the gas chamber 8. Next, when another switching valve 11 is operated, the gas chamber 8 expands to move the piston 4 in the direction of the arrow A, thereby the piston rod 5 is projected. By this constitution, the accumulator is unnecessitated and thereby the device can be made lighter in weight by the part thereof.

Title: Fuel cell power generation system
Inventor: AMAMIYA TAKASHI
IPC: H01M8/06
Filed: 1985-03-30
Abstract: PURPOSE:To reliability prevent any unusual temperature increase of the reformation tube of a fuel reformation device which accompanies a rapid load variation of a fuel cell without causing any great variation of the pressure of the fuel electrode and any reduction of the fuel reformation characteristic by controlling the distribution of the air flow rate according to the result of the comparison between the actually determined temperature and the standard temperature of the reformation tube by installing a high temperature and a low temperature exchanger. CONSTITUTION:When the load of a fuel cell rapidly decreases and the temperature of a reformation tube 2 exceeds a standard level, according to a command from a control device 30 immediately a control valve 27 is controlled to increase the flow rate of air and a control valve 24 is controlled to decrease the flow rate of air. Accordingly, part or most of the combustion air branches into a low temperature exchanger 26 and then is cooled by cooling water 28 prior to being poured into a burner 7 thereby producing a great cooling effect. In addition, the amount of air branching into the exchanger 26 is increased according to the temperature increases and its speed of the reformation tube 2. Therefore, any unusual increase in the internal temperature of the combustion chamber 6 of a fuel reformation device 1 as well as any unusual heating of the reformation tube 2 are prevented.

Abstract: PURPOSE:To enable high grade printing by stably operating a printing head by making a scanning speed almost constant, by a method wherein a handy printer main body is supported by a hand to be moved by utilizing the driving force of an auxiliary power device and the position of the main body is detected to perform printing operation corresponding to said position. CONSTITUTION:When an operator is ready to perform printing operation, a current is supplied to a DC motor 2 at first to rotate rollers A7, B8 but no control of printing is performed in this state and, therefore, a printing head 1 is not operated. Thereafter, when the operator carries a main body 1 to a position where rollers A, B are contacted with a recording medium 9 and is supported by a hand, the main body 1 is moved by the rotary power of the DC motor 2 and, when the operator pushes a switch 10, it is regarded that a printing order signal is generated from an external apparatus 15 and the control of printing is started. By continuing this control for some times (24 times by one character is a usual KANJI case), a character or a mark can be printed. This printing control is continued until the operator releases the switch 10.

IPC: H01L21/331
Filed: 1989-03-20
Abstract: PURPOSE:To decrease capacitance formed around base region by forming an outer base region only on one side of an inner base region. CONSTITUTION:A reverse conductivity type inner base region 17 is formed in a surface region 13 by ion implantation and the like in self-alignment with a pair of film regions 25 and 29. A pair of insulating regions 21a and 21b are formed on the side wall. Thereafter, an emitter lead-out region 23 containing impurities is formed. Impurities formed by ion implantation is activated by heat treatment. The impurities are diffused into the lower semiconductor surface region from one film region 25 and the emitter lead-out region 23. Thus an outer base region 27 and an emitter region 19 are formed. Therefore, an outer base region 27 is formed only on the right side of the inner base region 17 and is not formed on the left side of the inner base region 17. Since capacitance between the outer base region and a collector can be reduced to about 1/2, the total capacitance around the base region can be reduced to about 1/2.

Filed: 1982-04-23
Abstract: PURPOSE:To simplify the constitution of a controller, to omit a positioning mechanism, and a space needed for it, and to enable size reduction, by using a signal from a paper detector directly as a scanning start timing signal. CONSTITUTION:The image of an original 5c is scanned by movement of a contact glass plate 5a in the direction of an arrow AR2 synchronized to the rotation of a photosensitive drum 1 in the direction of an arrow AR1. The light reflected from the image is passed through a lense 2 and an image is formed on the position of the drum 1. The whole image of the original 5c is projected during plural rotations of the drum 1, and a corresponding latent image is formed. This latent image is developed with a developing device 6, and the toner image is transferred onto a recording paper fed from a register roll 10 at the transfer station beta just under a transfer charger 11. Since the paper is conveyed from the detection time of a paper detector 8 at a speed same as that of the drum 1 surface, the front end of the paper coincides with the front end of the original image formed on the drum 1, when the paper detection signal of the paper detector 8 is used as an original scanning start signal and the paper reaches the transfer position beta.
