Abstract: A fire detector consisting of a body and a base. An inner wall part is provided in a circumferential wall of the body in such a manner that the inner wall part can be cut away therefrom. Further, an engaging member abutting on the inner wall part is provided in the base. If it is unnecessary to lock the body to the base, the inner wall part is not cut away therefrom. In contrast, if it is necessary to lock the body to the base, the inner wall part is cut away therefrom. Thereby, the engaging member 12 can be fitted into a recess portion formed on the circumferential wall by cutting away the inner wall part therefrom. If the body is pushed against the base, a leading end of the engaging member is pushed up by the top surface of the circumferential wall. When the body being in such a state is turned in the circumferential or clockwise direction thereof to a fixing position at which the body is fixed, the leading end is fitted into the recess portion and moves downwardly.

Abstract: In a preferred embodiment, a device for sustaining longitudinal compressive loads applied to the ends thereof, the device including: a longitudinally extending tube; devices to seal the ends of the tube; pressurized fluid within the tube, the pressurized fluid having a pressure greater than the external pressure on the tube.

Abstract: The present invention provides an ionized water generating device enabling decreased manufacturing costs together with facilitating its mass production. Therefore, in the ionized water generating device generating ionized water by introducing tap water into a purifying block and an electrolyzing block installed in said device through a faucet, the device is characterized in that water channels connecting each of the functioning blocks are provided in an intermediate water channel block which is put together in one piece with a pair of plastic resin panels, and one of the panels is provided with a plurality of independent water passage respectively surrounded by shallow V-shaped grooves, and the other panel is provided with a plurality of V-shaped projections engaging with each of the V-shaped grooves to prevent leakage of water.

Abstract: An I/F portion 3 which connects and switches a CD-ROM drive 1 and a digital sound circuit 2 to a host computer 5, is provided to integrate the CD-ROM drive and the sound board. And at the left and right sides of an insertion entrance 35 of a cabinet 31 having an accommodation portion which accommodates a drive unit A of the CD-ROM , an amplifier 38 which outputs sound output to the speaker by amplifying the output from the CD-ROM drive unit A and a speaker 33 which operates by the output of the amplifier 38 are provided.

Abstract: An improved tool tray support assembly comprises a center section, opposed extensible lateral support members and end support assemblies. The end support assemblies fit onto end sections of the lateral support members, and support the assembly on opposed edges of an engine compartment of a motor vehicle. The lateral support members slide within the center section and can be locked at any desired position to adjust the spacing of the end supports to accommodate various engine compartments. The angular orientation of the center section can be varied by adjustment of the position of the lateral support members with respect to the end supports. Tool trays of standard dimensions fit between the opposed lateral rails of the support member to enable convenient storage of small tools and parts. The tool tray assembly may also be supported beneath a vehicle service lift or the like, and the tool trays may be supported by brackets on wheeled stools for increased flexibility in their use.
