The method of fabricating the electrode of a non-aqueous electrolyte secondary battery according to the invention comprises the steps of forming an electrode plate providing a positive electrode or a negative electrode of a non-aqueous electrolyte secondary battery and forming and attaching a porous film of a polymer material on the surface of the electrode plate thereby to produce the electrode plate having the porous film on the surface thereof.

Abstract: There are provided coiled electrode batteries with high yields, while short-circuiting in the batteries is prevented. A coiled electrode battery according to the invention has coiled electrodes consisting of positive and negative poles 21, 22 and two separators 23 lying between them. In the coiled electrodes, insulating layers 216, 226 made of insulating resin are formed on both sides of the proximal sections of the protrusions 213, 223 of the positive and negative poles 21, 22. Thus, even if the non-protruding sections of the positive and negative electrodes 21, 22 become exposed due to winding misalignment of the separators 23 in the lengthwise direction, the presence of the insulating layers 216, 226 prevents short-circuits between the proximal sections of the protrusions 213, 223 of the positive and negative electrodes 21, 22. As a result, yields are increased as short-circuits are avoided inside the battery.

Abstract: A rectangular case of a battery has cover, which is inserted into an open end of the case with the peripheral edge thereof butted against an inner periphery of the case, forming an interface to be welded. In order to form an equal weld penetration depth, the welding of the corners of the weld interface and straight sides thereof is carried out differently. For example, when the corner of the weld interface is welded, the laser beam is aimed at a portion offset outside the corner of the weld interface while the laser beam is applied right on the weld interface when the straight side is welded. Each portion on the straight sides is, preferably, welded before the above main welding for temporary setting.

Abstract: A thermal type flow rate sensor comprising a sensor chip having a rectangular shape. The sensor chip is supported between supporting pins through ribbon-like leads connected to opposite ends of the sensor chip. The ribbon-like leads serve to correctly locate the surface of the sensor chip with respect to flow of fluid. The surfaces of the sensor chip is formed with a thin film heater. A heater portion of the thin film heater comprises a plurality of straight portions and a plurality of turn portions connecting the straight portions to each other. Each turn portion is formed in a smoothly curved shape to avoid the concentration of electric currents and is disposed at an end portion of the sensor chip which has a comparatively low temperature. This structure is effective in preventing generation of cracks in the turn portions. In addition, the plurality of straight portions are alternatively inclined to effectively utilize the surface of the sensor chip to form a long heating portion.

Abstract: A cap with valve includes a cap body 1, a flange portion 5, and a gasket 11. The cap body 1 has an external threaded portion 2 for threadedly engaging a fuel supply inlet. The flange portion 5 extends outwardly in the radial direction from an upper portion of the cap body 1. The annular gasket 11 has a substantially circular cross-section, and is disposed on a sealing surface of the flange portion 5. This gasket 11 has a projecting portion 15A in contact with flange portion 5 and this projecting portion extends along the entire circumference of the toroidal gasket 11. The projecting portion 15 A absorbs surface irregularities on flange portion 5 thus eliminating the need for additional manufacturing steps, such as grinding, thereby reducing the manufacturing cost of the cap with valve.

Abstract: A fuel cap 1 for controlling the pressure within a fuel tank which has improved sealing properties between a valve member 43 of a pressure control valve 41 and a seat surface 35. The pressure control valve 41 opens and closes a flow path hole 33 in a cap body 5 so as to control the pressure within the fuel tank. In this pressure control valve, the valve member 43 is seated on the seat surface 35 in accordance with the force of a spring 71 and the pressure within the fuel tank. The valve member has a disk portion 49 which is flexed when the valve member receives a large pressure in a valve closing direction. An outer lip 57 and an inner lip 58 are formed on the disk portion 49. The outer lip 57 is seated on the seat surface 35 when the pressure within the fuel tank reaches a predetermined pressure. When the pressure increases further, the disk portion 49 is flexed, so that the inner lip 58 is also seated on the seat surface 35.

Abstract: A cap for a container such as a gas tank or radiator including a valve built therein. The valve built into the cap works to equalize pressure between that inside the container and the exterior environment. The cap includes a valve subassembly joined with the body of the cap, the valve subassembly functioning to equalize the pressure by allowing ingress or egress of air.

Abstract: A fuel cap where a valve body held to a valve support plate for performing pressure adjustment is arranged in a cap body installed to a filler neck of a fuel tank, and the part number can be decreased. The valve body has an outer circumferential lip element which is projected from an outer circumferential edge and pressed against an annular projection projecting inward in a fluid flow path of the cap body, and an inner circumferential lip element which is projected from an inner circumferential edge in reverse direction to the outer circumferential lip element. The valve support plate supports the valve body from rear side of the outer circumferential lip element, and has a seal member against which the inner circumferential lip element is pressed from the support position to inner circumferential side. Biasing means for pressing the outer circumferential lip element of the valve body is connected to the valve support plate.
