摘要： A blind rivet comprising a shank and a rivet body enclosing the shank, the rivet body containing in the cylindrical wall thereof wedge means and windows possessing spaces for admitting the wedge means such that, when the blind rivet is inserted through holes perforated in advance in the panels to be joined therewith and, subsequently, the shank is slid up the interior of the rivet body, the cylindrical wall of the rivet body is bent outwardly in the radial direction and, at the same time, the wedge means are raised and forced into the spaces of the windows, causing the cylindrical wall of the rivet body to be brought into tight contact with the edges of the holes in the panels and consequently enabling the blind rivet to be secured to the panels.

摘要： A resettable thermal cut-off fuse, under normal temperature condition, keeps the circuit in a closed state by allowing a switch member which is energized by a spring in the circuit-breaking direction to be joined through the medium of a thermal pellet capable of retaining a solid state under the normal temperature condition to a check means which is prevented from rotating in the spring's energizing direction. When the ambient temperature rises to a prescribed level and, consequently, the thermal pellet melts, the fuse allows the switch member to rotate in the spring's energizing direction to open the circuit. When the ambient temperature falls and returns to its normal level, the fuse can be manually reset by rotating in the circuit-making direction until it resumes firm engagement with the check means to close the circuit.

摘要： In a thermal cut-off fuse of the type in which a resilient contactor interposed between the electrodes opposed to each other inside a housing is bulged with the pressure resulting from insertion of a thermal pellet inside the housing so as to establish an electric circuit between the electrodes, desired reduction in the contact resistance between the contactor and the electrodes is accomplished by the improvement which comprises having formed on each of the opposite surfaces of the contactor confronting the opposed electrodes a plurality of raised contacts adapted so that all the raised contacts will remain in fast contact with the electrodes so long as the thermal pellet retains its solid state.

摘要： PROBLEM TO BE SOLVED: To support a load applied on a pocket coil, directly by the load support surface of a storage chamber for the pocket coil with which the end part of a stored compression coil spring makes internal contact. SOLUTION: Fixed mounting parts 4, each pointing to the direction of width, of a cylindrical body 3 formed that two side parts 20 and 20 extending along the direction of the length of belt-form cloth 2 are overlapped are formed with a distance therebetween in the direction of the length of the cylindrical body 3. A pocket coil is constituted that a compression coil spring 1 is stored in each of storage chambers 5 divided from each other by the respective fixed mounting parts 4 such that the winding axis of the coil points to the direction of the width of the cylindrical body 3. Constitution is that the height of the pocket coil P in a position where the fixed mounting part 4 is formed is not increased to a value higher than size between upper and under load support surfaces 6 and 6 of the pocket coil P with which the end part of the compression coil spring 1 in the storage chamber 5 makes internal contact.

摘要： PROBLEM TO BE SOLVED: To manufacture a clip holder for moving clips successively to the punching position. SOLUTION: Openings 14 into which ends of a clip pressing member for pressing a connecting section 2 without dropping the connecting section 2 of a clip 1 are formed at the given pitches by support sections 12 facing each other and horizontal crosspiece sections 13 disposed at the given intervals between support sections 12 in the longitudinal direction of the support sections 12, and engaging sections 15 holding releasably the ends of the connecting sections 2 and positioned on openings 4 are formed by the given pitches on the support sections 12 facing correspondingly to the openings 14.

摘要： PURPOSE:To elevate an accuracy by maintaining the switching of ON or OFF in order of an optical circuit between a light source and plural received light transmitting path means by a sectorial shielding plate, in accordance with the movement of a float in order in a height direction over the prearranged places. CONSTITUTION:A float supporting part 26 is divided into two branches and one end side of a rotary shaft 27 which penetrates both sides is fixed to a float supporting lever 25 via a float assisting frame 28. As the amount of liquid is increased then a shielding plate 29 starts to rotate to right according to the rise of a float 24 and the clockwise rotation of the rotary shaft 27 and a light receiving cable is released from the interposition of the shielding plate in a space from those connected to an empty indicating part at the left end, and an optical path is closed, and when a tank is filled up in due time and the float is lifted up, the shielding plate 29 is completely released from the space 22 and closes the optical path up to the light receiving cable of the right end corresponding to a fill-up indication F and the total indication parts of an indicator 8 are turned on. Since the detection of the height of a liquid surface can be correctly performed at the desired intervals by such an instrument, the accuracy is elevated.
