A hand-held staple gun comprises a housing, a driver, a spring means, a handle, and a safe actuation mechanism. The safe actuation mechanism includes a swing means, a link, and an actuation control rod. The swing means is pivotally secured to the housing and the link is pivotally connected with the swing means. When the staple gun is not in use, the link cannot engage the driver even if the handle is pressed down, and when the staple gun is in use, the actuation control rod is pressed upward int...

A toy support structure includes, a plurality of pivots provided on a center housing such that each axle center of the pivots is parallel to the axle center of center housing. By rotatably connecting the pivots and the hanging support set, the hanging support set can rotate in relation to the pivots so as to extend in radial form. Further, the hanging support set can rotate in relation to the pivots so as to be arranged in parallel on the same plane, thereby reducing the volume and accomplishing...

A triggering device of a nail driver has a single shooting mode and a continuous shooting mode. The triggering device is installed between a safety bar and a trigger of a driver body of the nail driver. The safety bar has an push sleeve extending out of a beating opening of the driver body; a trigger valve being on the driver body at an inner side of the trigger; a valve rod being in the trigger valve. When the trigger is triggered, the valve rod will be actuated so as to open the trigger valve ...

A magazine of a staple tacker includes a base plate and a cover slidably engaged to the base plate, the base plate having a stop disposed to an inner side thereof, the cover having a ridge extending from an outer surface thereof and an actuator pivotally mounted to the ridge with a spring biasedly disposed between the actuator and the ridge, the actuator having two side plates which extend through corresponding slots defined in the cover to contact the stop, a cap member having an open end for t...

A rotary developing device which facilitates a positional adjustment of developing units and prevents the developing units from being shifted even when they are used for a long period. Pins protruding from a revolver are inserted into elongated holes formed in developing units so that developing units are held in such a manner that the developing units are movable relative to the revolver. By mounting a spacer between the elongated hole and the pin, the positional adjustment of the photosensitiv...

Sintered shaped bodies are made of a pulverulent mixture of tin, copper and predominantly iron by sintering the mixture in which tin is present in an amount between 0.5 and 4.5%, copper is present in an amount of 0.3 to 7%, balance iron, and wherein the ratio of tin to copper is between 1 : 0.7 and 1 : 1.5. The formed sintered body is then cooled to for instance room temperature and thereafter subjected to a tempering treatment at a temperature between 750.degree. and 600.degree.C followed by co...

Stapler having a staple track locked in the base by means of a resilient plastic latch.

A stapler of the type having a top cover member and lever member mounted for pivotal movement between an operative position disposed in closing relation with the open top of the magazine chamber of a magazine member and a staple stick loading position displaced approximately 180.degree., a staple stick pusher mounted slidable on a mounting rod within the magazine chamber and a flexible elongated pusher retracting member molded of plastic material having one end portion abutting the pusher apertu...

The present invention relates to fatty acids. In particular, the present invention provides polyconjugated fatty acids, and methods of their synthesis and their use.

An ant exterminating apparatus operates to exterminate an ant colony using a energy producing element secured within a housing. The ant exterminating apparatus further includes a cover that is pivotally attached to a base plate. The cover is pivotable between an open position and a closed position, and an energy producing element is affixed to the cover to quickly generate radiation or heat energy between the cover and the base plate upon command of either the user or a conventional timing devic...
