Title: Temperature controller of fuel cell
Inventor: TAGUMA YOSHIYUKI
IPC: H01M8/04
Filed: 1986-03-25
Abstract: PURPOSE:To make a structure compact, simple, and inexpensive by connecting a plurality of cooling pipes with common first and second manifold pipes, and connecting the first manifold pipe with a radiator and the second manifold pipe with a heater. CONSTITUTION:When a fuel cell 11 is heated, supply of cooling water to a radiator 13 is stopped, and a heating medium such as steam and hot water is passed to a drum 18 of a heater 16. A heating medium in a tube 17 of the heater 16 is heated by the heating medium in the drum 8. The heating medium whose density is decreased by increase in temperature rises through the second manifold pipe 10b and reaches a cooling pipe 7 through the second header pipe 9b and the second connecting pipeline 8a by buoyancy based on the difference in density to a heating medium in the cooling pipe 7. The heating medium gives heat to a cooling plate 6 to heat the fuel cell 11. The heating medium whose density is increased by losing heat falls the cooling pipe 7, the second connecting pipeline 8b, the second header pipe 9b, and the second manifold pipe 10b by gravity and returns to the tube 17 of heater 16. When the fuel cell 11 is cooled, the vapor generated in the fuel cell 11 is cooled in the radiator 13 and circulated.

Filed: 1978-06-07
Abstract: PURPOSE: To permit the high density automatic wiring of a number of insulated small-diameter conductors by making the ultrasonic junction of conductors coated with a thermo-melting insulator while melting the insulator by means of a heat produced by a vibrating friction.  
     CONSTITUTION: A conductor coated with a thermo-melting insulator, e.g., an approx. 40 micron diameter copper conductor coated with polyurethane resin, etc., is used. The insulating coat is such as to be melted at approx. 300°C and also removable by blushing, etc. Using an ultrasonic wire bonding, etc., the capillary 6 for connection which is applied an ultrasonic wave is wound with the coil heater to heat it to a necessary temperature by passage of pulse current, whereupon the contact point 8a supported by the capillary 6 is locally heated to melt and upon contacting with the lead 4 by pressure, a vibrating friction is produced between the contact point 8a and the terminal 4, resulting in the removal of the insulator and the completion of ultrasonic junction of conductors. Thus, the connecting operation can be shortened and also its yield can be raised.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily rescatter a sediment in an ink tank by constituting a stirring member stored in an ink writing instrument in a freely movable manner of plumb parts and an elastic material connecting and fixing these plumb parts. SOLUTION: In a writing instrument of such a type that a valve is released by the sliding of a pen point 1, a stirring member 10 is constituted of two plumb parts 10a, 10b and a coil spring 10c as an elastic material which connects the plumb part 10a to the plumb part 10b. When the plumb 10a on the front side of the stirring member 10 is buried deep into the sediment 9a of an ink component, the supply of an ink into the ink through hole 4a of a valve seat 4 fails and the ink in the pen point is depleted, resulting in the generation of a blur in writing. Therefore, if the writing instrument is shaken, the plumb part 10b is vibrated into a motion which in turn, is transmitted to the coil spring 10c and the plumb part 10a buried in the sediment 9a. Consequently, the sediment 9a is rescattered to its original state, and the wiring instrument is recovered to a normal use condition.

Title: Device for supplying fuel
Inventor: KIMATA KEI
IPC: F02D3/02
Filed: 1978-06-09
Abstract: PURPOSE: To finely pulverize fuel by coinciding both fuel injecting direction and air stream direction.  
     CONSTITUTION: In order to accelerate the pulverization of fuel in a fuel ejector 19, the ejector 19 is so disposed at the center line thereof as to be coincident to that of the throttle body 23a of a suction manifold 23 on the same axes at the upstream of a throttle valve 22 and in a manner that the injection directing is coincident to the air stream direction flowing through the manifold 23.
