Abstract: A pressure regulation device is attached to a waterproof case and regulates pressure within the waterproof case. The device has abase part for attachment to the waterproof case and an air conduit is joined with the base part so as to extend in the direction away from the waterproof case when the base part is attached to the waterproof case. The air conduit has first and second apertures, such that the first aperture is joined to the base part and communicates with the interior of the waterproof case and the second aperture communicates with the surrounding atmosphere. The air conduit has at least one bent part between the first and second apertures, and the second aperture is arranged between the bent part and the first end part in the height direction perpendicular to the base part.

Abstract: A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member movably coupled to the flange unit. The joint member is configured to move in an upward/downward direction relative to the flange unit. Two side tubular portions extend from the flange unit in the upward/downward direction and are positioned side-by-side. Column portions extend in the upward/downward direction from the joint member. The column portions are moveably disposed in the side tubular portions. The column portions are configured to move in the upward/downward direction relative to the side tubular portions. The side tubular portions are connected to each other via a rear side wall and a front side wall of a center tubular portion disposed between the side tubular portions.

Abstract: A fuel supply device includes a fuel supply passage, a fuel pump, a pressure-regulating valve, and a housing. The fuel supply passage is in communication with the fuel injector. The fuel pump pumps the fuel to the fuel supply passage. The pressure-regulating valve regulates the pressure of the fuel in the fuel supply passage. The housing is disposed in the fuel tank. The housing accommodates the fuel pump and the pressure-regulating valve. The fuel supply passage is formed within the housing. The pressure-regulating valve is connected to an end portion of the fuel supply passage formed in the housing. The volume of the end portion of the fuel supply passage in the housing is configured to increase with increasing pressure of the fuel.

Abstract: A sender gauge adaptor includes an adaptor body pressed against a bottom wall of a fuel tank by a spring. The adaptor body includes a suction inlet part having a hollow cylindrical shape that opens downward. Recesses allowing fluid communication between the interior and the exterior of the suction inlet part and projection parts having a polygonal-shaped lower surfaces are alternately arranged in the circumferential direction along a lower end of the suction opening. The adaptor body includes a seat part in surface contact with the bottom wall of the fuel tank at a position below the lower surfaces of the projection parts.

Abstract: A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member connected to the flange unit. The joint member is movable in an upward/downward direction. The flange unit includes a side tubular portion extending in the upward/downward direction. The joint member includes a support column portion extending in the upward/downward direction. The support column portion is movably disposed in the side tubular portion so as to be movable in the upward/downward direction. The support column portion is connected to the side tubular portion by a snap-fit so as to be movable and suspendable in the upward/downward direction.

Abstract: A fuel passage structure of a fuel supply device is configured to supply fuel from a fuel tank to an internal combustion engine. The fuel passage structure includes a passage-forming member that forms a fuel passage and a check valve. The fuel passage includes a vertical passage extending in a vertical direction and a lateral passage extending in a horizontal direction. The check valve is disposed at an intersection of the vertical passage and the lateral passage. The check valve includes a valve body configured to close under its own weight. The valve body is movably arranged within the vertical passage in the vertical direction. The check valve is provided with a restriction member which restricts movement of the valve body into the lateral passage, while at the same time the restriction member does not disturb the forward flow of the pressurized fuel.

Abstract: A fuel supply system has a fuel tank, a sub-tank, a fuel pump, an attachment member, and one or more shaft members. The fuel tank has an upper wall and a lower wall. The sub-tank is located on the lower wall inside the fuel tank and has one or more guide portions. The fuel pump is housed in the sub-tank. The attachment member is attached to the upper wall of the fuel tank and has a plurality of support portions. The shaft members are attached to the support portions so as to extend downward from the support portions and are slidably inserted into the guide portions of the sub-tank, respectively, such that the attachment member is connected with the sub-tank and is movable relative to the sub-tank in the vertical direction. The number of the support portions is greater than the number of the shaft members. The shaft members are selectively attached to the support portions.

Abstract: An ultraviolet irradiation apparatus for curing an ultraviolet curable coating agent applied to a substrate, by irradiating an ultraviolet light to the ultraviolet curable coating agent, which includes a low-pressure mercury lamp as a light source. According to the present invention, the problems associated with the use of an ultraviolet irradiation apparatus, whose light source is a high-pressure mercury lamp, can be solved, such as the need of a high voltage power source, degradation of quality, potential hazard to operators and the like. The present invention also provides a method of forming a cured coating film having the same properties as achieved by the use of a high-pressure mercury lamp, such as resistance to stain, adhesion to substrate and the like. This method requires a shorter time for curing of a unit area of the film as compared to the use of a high-pressure mercury lamp (100 V type).

Abstract: An error correcting and controlling system having syndrome generating means for generating syndromes of data to be checked and memory means for storing error bit positions in which system the syndromes form addressing inputs to the memory so that the error bit position information stored in the address positions corresponding to each syndrome in the memory may be read out and processed for the purposes of error detection and correction. As a result, the check circuits of the present system have been simplified as compared with conventional check circuits.
