A power controller for an appliance, especially a washing machine, is operative to place the appliance into a hyperspin mode. When in the hyperspin mode, the washing machine rotates its washing basket at a higher speed in relation to a traditional spin mode for the washing machine. In order to prevent damage to the washing machine that could result from spinning heavier, unbalanced loads at higher speeds (i.e. hyperspin speeds), a controller detects vibration of the washing machine basket while ...

A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. This coating is molecularly bonded to the tungsten carbide and is not an alloy. The unique properties of the shot pellet allow its density to be tailored. Under this process, the effective density of the pellet can be made to be identical to lead for direct replacement in current lead loading formulations. Additionally, the density can be made to be lower than lead for shotguns requ...

A differential device has a power-transmitting member mounted to undergo rotation in forward and reverse directions about a central rotational axis and to undergo linear movement in a direction along the central rotational axis. The power-transmitting member has meshing claws each having an inclined surface. A pair of driven shafts are mounted to undergo rotation about the central axis. A pair of rotational driven members have meshing claws confronting and for meshing engagement with the meshing...

An extremely light weight one-piece "thin-skin" molded RV body that can be manufactured without a heavy steel chassis frame, and which construction method minimizes costly hand labor . . . while lending itself to automated assembly line manufacturing processes as used in the automotive and sport boat industries. Aspects include a variable-height suspension system to decrease frontal area when towed, and which raises the body for use of slideouts; a streamlined storage nose cap that reduces air t...

A lighting device includes a handheld unit, a light bulb, and an accessory unit. The handheld unit defines a battery compartment, and includes a screw hole formed in one end of the handheld unit. The light bulb engages threadedly the screw hole. The accessory unit includes a positioning member attached to the end of the handheld unit, an arm extending outwardly from the positioning member and inclining with respect to an axis of the screw hole, and an accessory member connected to the arm and of...

An x-ray scanning imaging apparatus with a rotatably fixed generally O-shaped gantry ring, which is connected on one end of the ring to support structure, such as a mobile cart, ceiling, floor, wall, or patient table, in a cantilevered fashion. The circular gantry housing remains rotatably fixed and carries an x-ray image-scanning device that can be rotated inside the gantry around the object being imaged either continuously or in a step-wise fashion. The ring can be connected rigidly to the sup...

A plurality of lighting structures is provided for enhancing the visibility of a human powered vehicle at night. The visibility enhanced human powered vehicle has a frame with attached wheels having tires including sidewalls. The safety lighting structures include at least one photo-luminescent section and at least one reflective section being located on at least one of the wheels. A light source is attachable to the human powered vehicle to direct light against the photo-luminescent sections.

A structure of multi-directions socket for Christmas light includes a pair of first and a second sockets alternately and juxtaposedly integrated with one another toward opposite directions, a vertical slender common copper plate disposed between the sockets having a contact upper end engaged in an inner wall of the first socket and a hooked lower end retained in the second socket, a pair of electric wires each having a contact plate at inner end respectively inserted into the bottom and secured ...

Detonating projectiles are fired into a target area by a weapon, the time between firing and detonation being one second or less. By setting the target location at the same distance as e.g. the edge (1) of a building (3), however laterally displaced with respect to that edge, it is possible to obtain an effect also in an area invisible to the bearer of the weapon. For simulating this weapon, for example in house-to-house fighting, it is proposed to affix devices (5) comprising a sensor (22) and ...

A semiconductor light emitting device with improved luminous efficiency is provided. An underlying n-type GaN layer is grown on a sapphire substrate, and a growth mask made from SiO.sub.2 film or the like is formed on the underlying n-type GaN layer. An n-type GaN layer having a hexagonal pyramid shape is selectively grown on a portion, exposed from an opening of the growth mask, of the underlying n-type GaN layer. The growth mask is removed by etching, and then an active layer and a p-type GaN ...
