A method of making a resonant frequency tag which resonates at a predetermined frequency comprises the steps of forming a first conductive pattern comprising an inductive element and a first land, the first land having a first end connected to one end of the inductive element, and a second end spaced a predetermined distance from the first end; separately forming a second conductive pattern comprising a second land and a link element, the second land having a predetermined width; placing the second conductive pattern proximate to the first conductive pattern at a first predetermined location so that the second land overlies at least a portion of the first land with a dielectric therebetween to establish the plates of a capacitive element with a first predetermined capacitance which with the inductive element forms a resonant circuit; measuring the resonant frequency of the resonant circuit and comparing the measured frequency with the predetermined frequency; if the resonant frequency does not match the predetermined frequency within a selected tolerance, moving the second conductive pattern so that the second land moves along the length of the first land to thereby change the capacitance of the capacitive element; repeating the last two steps until a match occurs; and securing the second conductive pattern to the first conductive pattern.

The front surface of a wooden overlay sheet, having a wooden material on the front surface thereof, is subjected to a color treatment with a colorant comprising a primer resin; the wooden overlay sheet, which was subjected to color treatment, is positioned in a metal mold for molding, and a transparent resin layer is molded on the front surface thereof by means of injection-molding. Furthermore, a synthetic resin core material is molded on the rear surface of the wooden overlay sheet. A composite molded article is thereby produced, wherein a synthetic resin core material is molded on the rear surface of the wooden overlay material, and a transparent resin layer is molded on the front surface of the wooden overlay sheet. Thus, the present invention enables the enhancement of the outer appearance of the product and the enhancement of the adhesion of the wooden overlay sheet and the transparent resin layer.

A semiconductor relay circuit includes a MOS FET receiving a photovoltaic output generated across a photovoltaic diode array. The photovoltaic diode array is responsive to a light signal from a light-emitting element. A cross gate and source electrodes of a MOS FET is connected a control circuit which is at a high impedance state during the generation of the photovoltaic output but to be at a low impedance state upon disappearance of the output. Additionally, resistors are inserted in series respectively in each of current, one path flowing from the photovoltaic diode array across the gate and source electrodes of the MOS FET and the other path flowing a discharge current from a capacity across the gate and source electrodes of the MOS FET to the control circuit, whereby the setting of rise and fall of circuit output signals can be made easier.

A method of manufacturing a high pressure fluid supply pipe of a double pipe structure in which an outer pipe is tightly fit over the outer circumference of an inner pipe, wherein the method comprises a step of forming a double pipe by tightly fitting an inner pipe with an outer pipe having a thermal expansion coefficient greater than that of the inner pipe while putting a brazing material therebetween, and a step of subjecting the double pipe to a heat treatment and then to a gradual cooling treatment to join and tightly fit the inner pipe and the outer pipe integrally to each other, thereby providing at least the inner surface of the inner pipe with a compressive residual stress. The resistance to high inner pressure can be improved and destructive strength, in particular, fatigue resistance to the repeated inner pressure can remarkably be improved.

There is disclosed a method of fabricating a double pipe capable of attenuating vibration. The pipe can be used in an automobile exhaust system. The method is initiated with forming a coating either on the outer surface of an inner pipe or on the inner surface of the outer pipe. The coating is made from an epoxy resin, an acrylic resin, or other resin. The inner pipe is inserted into the outer pipe, and then they are brought into intimate contact with each other via the coating to couple them together. The coupled pipes are heated beyond 400.degree. C.
