Abstract: A wire loop comprises a wire connecting a first bonding point and a second bonding point therethrough, wherein the wire includes a ball bonded to the first bonding point, a neck portion adjacent to the ball and a major portion extending from the neck portion to the second bonding point. The neck portion includes a riser part which extends, from the bonded ball, obliquely upward in a direction toward the second bonding point, and the riser part is formed by a top portion of the ball which has entered an opening of a capillary and been shaped at the time of ball bonding. The riser part is formed by inclining the top portion of the ball, which enters the opening of the capillary at the time of ball bonding, which inclining is done by moving the capillary obliquely upward toward the second bonding point.

Abstract: An elastic endless crawler including an annular belt-shaped elastic crawler body, the crawler body includes a series of driven elements for operation of the crawler and a reference plane which passes through respective centers of the drive elements and extends in a longitudinal direction of the crawler, and a thickness of one side relative to the reference plane and a thickness of the other side relative to the reference plane are different from one another. The lengths between respective crawler body end surfaces facing in a crawler widthwise direction, and the reference lane are different from one another. A thickness of one side, which is shorter in length, of the crawler body is greater than that of the other side, which is longer in length, of the crawler body.

Abstract: In an elastic endless crawler comprising an annular belt-shaped elastic crawler body, according to the present invention, the crawler body comprises a series of driven elements for operation of the crawler and a reference plane, which reference plane passes through respective centers of the drive elements and extends in a longitudinal direction of the crawler, and a thickness of one side relative to the reference plane and a thickness of the other side relative to the reference plane are different from one another. Preferably, lengths between respective crawler body end surfaces facing in a crawler widthwise direction, and the reference plane are different from one another. Further, preferably, a thickness of one side, which is shorter in length, of the crawler body is greater than that of the other side, which is longer in length, of the crawler body.

Abstract: An annular elastic track having sprocket-driven protrusions on the inner circumference and lugs on the outer circumference. The annular elastic track comprises a plurality of annular thin plates spaced radially from one another with a predetermined interval and embedded in layers in the track in its circumferential direction. The annular thin plates are a plurality of concentric annular plates having different diameters or a spirally formed single thin plate. Such an annular elastic track is used for vehicles as well as a monocycle comprising a flat plate-shaped cross-section, at least two external rollers arranged outside the annular elastic track for applying a load onto it, at least one internal roller arranged inside the annular elastic track to hold the track by these internal and external rollers therebetween, and crank device including pedals provided inside the annular elastic track for driving one of said external and internal rollers.

Abstract: A carbon dioxide clathrate having a lump diameter enough to precipitate on a desired abyssal position of the sea without being drifted by a seawater flow of the abyss can be produced by bringing an aqueous solution into contact with carbon dioxide with the interposition of an interface in a reactor and retaining this contact; adjusting the pressure in the reactor to 13 atm or more, the temperature of the aqueous solution to a level of more than 5.degree. C. to 10.degree. C., the temperature of the interface to a level of more than 10.degree. C. to 15.degree. C. and the temperature of a lug inserted into the aqueous solution to a level of more than 0.degree. C. to 5.degree. C.; producing/growing the carbon dioxide clathrate on the lug; and then heating the lug to a temperature of more than 10.degree. C. to 30.degree. C. to separate/drop the carbon dioxide clathrate therefrom.

Abstract: A power generation system with flat fuel cells of solid electrolyte construction permits the building up of a large capacity system. There are a train of pile units of flat fuel cells of solid electrolyte disposed in a horizontally extending fuel gas duct. The gas fuel duct supplies to the train of pile units of flat fuel cells fuel gas. Each of said pile units of flat fuel cells has a horizontal flat flow path for the fuel gas disposed above each fuel-side porous electrode sheet of the fuel cell opening freely at two path ends on the opposing side faces of the pile unit. There is a horizontal flat flow path for the oxidant gas disposed beneath each oxygen-side porous electrode sheet separated from the fuel gas flow paths and each connected at two path ends to either a supply line or to an exhaust line for the oxidant gas.

Abstract: A cylindrical solid electrolytic fuel cell which includes an oxygen electrode constituting the innermost layer of the fuel cell and having a thickness of 1 mm or more, a solid electrolyte covering the outer peripheral surface of the oxygen electrode, and a fuel electrode covering the outer peripheral surface of the solid electrolyte, is disclosed.

Abstract: An SiO.sub.2 insulating layer is formed on an Si substrate, and an Si.sub.3 N.sub.4 insulating layer is formed on the SiO.sub.2 layer. A notch is formed in the Si.sub.3 N.sub.4 layer using a resist film as a mask. The SiO.sub.2 layer is etched using the Si.sub.3 N.sub.4 layer as a mask, thereby forming an opening larger than the notch cut in the SiO.sub.2 layer. As a result, the Si.sub.3 N.sub.4 layer extends over the opening in an overhanging manner. When As.sup.+ ions are implanted in the periphery of the notch of the Si.sub.3 N.sub.4 layer, the ion-implanted portion of the Si.sub.3 N.sub.4 layer is arcuated toward the base region. When a metal such as Ti is deposited on the arcuated portion, the metal is also deposited on the arcuated portion and the portion of the emitter region matching with the notch, thereby forming an emitter electrode portion.
