The present invention discloses a conductive composition comprising a plurality of polymers and at least one conductive filler. The polymers are compatible under a molecular size and the form of the conductive filler includes a flake. The conductive composition of the present invention owns better electrical characteristics than a conventional conductive composition that comprises a single polymer. The present invention further discloses an over-current protection device comprising two metal foils and a PTC (positive temperature coefficient; PTC) composition layer. The PTC composition layer contains the conductive composition.

The invention is relative to a ceramic socket, which is established on the baseboard of lamps and lanterns through bearing leg. The said socket consists of a body and a cap. The lateral side of body where the cap fastens on it and towards the baseboard has wire entrances for polar wires. Polar wires go into the baseboard through their independent entrance connect to corresponding slug and tongue in order to settle wires between the socket and the baseboard. This structure avoids the shadow projected on the lamp body to affect the appearance. On the other hand, wires being concealed between the socket and the baseboard are isolated from lamps. Even it multiple lamps sit on a single socket, this structure will still remove hidden peril of short circuit even when the electrical insulating material of the wire sheet is heated or damaged

The present invention is an air permeable and waterproof stretchable woven fabric. It is a multi-functional woven fabric comprising the following processes: warping and weaving the warps and the wefts to obtain a gray fabric; adding stretchable yarns into the warps and the wefts; and, dyeing and finishing the gray fabric. Accordingly, without coating with or laminating rubbers or films, the fabric can obtain elasticity and better stretchability in the directions of the longitude or the latitude or both and is also waterproof and highly air permeable.

A wireless network transmission device is disclosed. A network control chip, a communication control chip and a control chip set are arranged in parallel. The network control chip, communication control chip, and control chip set are connected to the first USP module and the second USP module through a bus. The first USP module is connected to an external network communication protocol module and the second USP module is connected an external mobile phone communication protocol module. Thus, the system is communicable with network communication protocol module and mobile phone communication protocol module in parallel; thereby, data of different protocols being transmitted in one device. The control chip set serves to connect a PCMCIA interface to the first USP module and second USP module through the network control chip and the communication control chip.

A case coupling and reinforcing structure is provided on an inner surface of a first and a second case of an apparatus. The first and the second case are primarily assembled and locked to each other using a plurality of screws. The case coupling and reinforcing structure includes a plurality of perpendicular rib reinforcements spaced along an inner side of a peripheral edge of the first case, and a plurality of cuts provided on a peripheral edge of the second case at positions corresponding to the rib reinforcements, such that the rib reinforcements are tightly received in and engaged with the cuts when the first and the second case are assembled to each other, giving the assembled cases a reinforced structural strength to enable a reduced number of screws being used and a reduced material thickness of the casing, and accordingly, reduced material and manufacturing costs of the casing.
摘要:
An electric generating device includes a rotatable shaft, an electric generator having one or more rotors coupled to and driven by the shaft, and one or more flywheels attached to the shaft and rotated in concert with the shaft, the flywheels each includes one or more weight members for increasing a moment of inertia to the flywheels and for facilitating a rotational movement of the flywheels and the shaft. It is preferable that the weight members are attached the outer peripheral portions of the flywheels. The weight members of the flywheels are angularly offset from each other for stabilizing the flywheels and the shaft.
摘要:
An external optical disk stabilizer, for use in stabilizing an optical disk comprising a coating of self-adhesive material set to a non-recording side of an optical disk substrate. The self-adhesive viscous material includes silicon gel, epoxy or other like material. The stabilizer may include a thin sheet of dampening material permanently or non-permanently applied over the non-recording side. The stabilizer may also sandwich the optical disk therebetween.
