Abstract: A high frequency module includes a layered substrate and an element for outputting a reception signal in a balanced state. The element includes a first and a second output terminal and is mounted on the top surface of the layered substrate. A first and a second reception signal terminal are disposed on the bottom surface of the layered substrate. The high frequency module further includes a first signal path connecting the first output terminal and the first reception signal terminal to each other, and a second signal path connecting the second output terminal and the second reception signal terminal to each other. The first and second signal paths are each formed using one or more through holes provided inside the layered substrate, and are not exposed at any side surface of the layered substrate.

Abstract: A fuse 1 of the present invention includes a fuse body 32, a housing 33 which is made of an insulative resin, and receives and holds the fuse body therein, the fuse body being inserted into the housing through an upper opening in the housing, and a cover 34 which is made of an insulative resin, and covers the upper opening in the housing. Retaining portions 50, corresponding respectively to retaining claws 47 of a withdrawing jig for withdrawing the housing, are formed at a side surface of the housing. Therefore, the retaining claws of the withdrawing jig can be positively fixed to the housing, and a relatively large force is not required for the withdrawing operation, and therefore the withdrawing operation can be effected efficiently.

Abstract: A fuse unit includes first and second fuse devices. Each of the fuse devices includes a attaching portion to be attached to a battery terminal of a battery, a housing provided on the attaching portion and having a cavity which is opened forward and backward of the housing, and a fuse body having a first end which is electrically connected to the battery terminal and a second end which is covered with the housing to form a wire connection part, the fuse body having a fusible portion which is disposed in the cavity. When the housings are superposed in a direction away from the battery, at least one of the housings and the fuse bodies are constructed so that the fusible portions are checked as viewed in a forward direction of the housings.

Abstract: A fuse includes a fuse element contained in an insulating housing made of synthetic resin. The insulating housing which includes a pair of housing bodies and an upper wall portion mutually connecting upper ends of the housing bodies is adapted to cover inner edges and upper edges of flat plate terminal portions and a fusible portion. On one side edge of a slit opening formed at a lower end of the insulating housing, a flap is continuously provided through a thin-walled hinge so as to freely rotate. The flap is rotated to a closed position in a state where the fuse element has been inserted into the insulating housing, and locked to locking projections which are projected from the inner edges of the respective flat plate terminal portions. The distal end edge of the flap which is abutted against the other side edge of the slit opening is joined by ultrasonic welding, thermal welding or the like.

Abstract: Disclosed are a process for laminating a functionally gradient material and a laminating apparatus for the same. The process therefor includes a suspending step and a functionally gradient material laminating step. In the functionally gradient material laminating step, solid-liquid separation is carried out to a suspension while varying the mixing rates of the suspension particles contained therein continuously or in a multi-staged stepwise manner. Therefore, the functionally gradient material layer thus laminated offers a composition gradient varying continuously or in a multi-staged stepwise manner in the thicknesswise direction thereof in a superior continuity, and the composition fluctuates less in the planewise direction thereof. In addition, the process and the laminating apparatus have obviated the atomizing and the spraying which adversely affect a working environment.
