Abstract:
A pull exerciser includes a handle, a resilient cord including an end piece attached to an end thereof, and a positioning plate. The positioning plate includes several holes that allow passage of the end piece of the resilient cord through the positioning plate. The positioning plate further includes several retaining slots each having a cord-receiving portion and a guiding portion. The respective cord-receiving portion has a diameter smaller than that of the end piece of the resilient cord. The respective cord-receiving hole is communicated with the outside via the respective guiding portion. The respective guiding portion includes a reduced section having a diameter smaller than that of the resilient cord. The resilient cord extends through the handle and the respective hole, and the resilient cord is removably, forcibly inserted into the respective cord-receiving hole through the respective guiding portion.
Abstract:
A method for regulating the skin and hair color in a post-natal mammalian by preparing a recombinant vector in which an agouti-encoding DNA segment is positioned under the control of a promoter and introducing the recombinant vector into skin cells of the mammalian. The recombinant vector carrying the genes expresses related proteins after they are introduced to most mammalian cells.
Abstract:
A temperature-homogenizing device for uniformly dissipating heat generated from electronic components in an electronic device to a housing of the electronic device includes a first and a second higher thermally conductive layers and a first lower thermally conductive layer. The first lower thermally conductive layer is disposed between the first and the second higher thermally conductive layers, and made of a material or a medium having a lower thermal conductivity than each of the first and the second higher thermally conductive layers. By means of this temperature-homogenizing device, the heat is homogeneously distributed throughout the first and the second higher thermally conductive layers at a higher thermal conduction rate and transferred through the first lower thermally conductive layer at a lower thermal conduction rate so as to maintain homogeneous temperature distribution on the housing.

The present invention is an electropolishing process and device for electropolishing an inner surface of a long tube, especially applied to a long tube of greater than two meters and a diameter range between 0.3 and 5 cm. Wherein, the present invention comprises at least one tube, and one complex electrode. An inner surface of the tube is for electropolishing process, and it is an anode as well. The electrode is a cathode and placed on a center of a partition. An end of electrode connects to a cable, the cable is driven by an axial mechanism to be moved the electrode toward the axial mechanism itself. Inside of the tube is full o electrolyte, which is an electrifying medium to connect both anode and cathode. Further, electrolyte cooperates with the electrode to perform the electropolishing process on the inner surface of tube.
Abstract:
A uniform pressure type three-dimensional pressure bearing surface measuring instrument structure includes a housing, multiple measuring rods, multiple height sensors, multiple connection support cylinders, and multiple connection pipes. The connection support cylinders are connected with the connection pipes which are connected with each other, so that the connection support cylinders and the connection pipes may form a pressure connection system. Thus, the three-dimensional pressure bearing surface measuring instrument structure may be used to the pressure distribution of the user's hip by measuring the height variation of the measuring rods, thereby forming a three-dimensional spatial curve of a constant pressure so as to make a seat cushion of a constant pressure according to the three-dimensional spatial curve, so that the seat cushion may satisfy the ergonomic design.

A circuit board indicator comprises a plurality of lamps with cut and bent terminals, an outer plastic holder and an inner plastic holder. The outer plastic holder contains an accommodating chamber, which has a plurality of rounded holes on a lateral side thereof. The inner plastic holder has a plurality of positioning recesses and each of the positioning recesses has a guiding slot on topside thereof. The terminals of the lamps are guided by the guiding slot and inserted into corresponding positioning recesses. The inner plastic holder further has a plurality of clamping dents to clamp corresponding lamps. The inner plastic holder has barbs on two lateral sides thereof and corresponding to rectangular grooves on the outer plastic holder. The barbs are engaged into corresponding rectangular grooves when the inner plastic holder is assembled to the outer plastic holder.
Abstract:
An automatic turning headlight structure includes a headlight structure, a running gear and a server, the headlight structure being mounted through a rotatable main shaft at the front side of the car. The server is placed inside the headlight structure, and connected by a shaft with the main shaft. The server receives a signal to turn and to transmit a force to the shaft to drive the main shaft to make the headlight turn left or right, following the movement of the steering wheel.

Abstract:
A liquid level controller comprises of a control circuit, a control box, a sump pump, and a liquid level indicating means, the liquid level indicating means comprising a high level indicating device and an impulse indicating device, the high level indicating device and the impulse indicating device comprising pipe bodies, magnetic switches, floating element or impulse element. The pipe body of the impulse indicating device has a connecting pipe connected to the side thereof. The magnetic switches located on the top of the pipe bodies and connected to the control circuit with electric wires. When the liquid surface raises and buoys the floating element of the high level indicating device to contact the magnetic switch, the magnetic switch produces a signal to the control circuit and the sump pump is started to draw the liquid out of the tank. The liquid is drawn through the impulse indicating device, the impulse element, of the impulse indicating device is raised by the buoyancy of the liquid to contact the magnetic switch, then the sump pump is controlled by the impulse indicating device and the liquid is drawn out until the impulse force of liquid is not strong enough to support the impulse element, that is, the liquid is completely drawn out.
Abstract:
An electrically programmable and electrically erasable MOS memory device having a floating gate which is separated from the semiconductor substrate by a thin oxide layer, the memory device also having an impurity implant in the substrate which extends under an edge of the floating gate beneath the thin oxide layer. In one embodiment the thin oxide layer underlies the entire floating gate while in another embodiment only a portion of a small thin side window extends under the floating gate's edge. Also disclosed is a fabrication process in which the one embodiment is formed by first forming the floating gate over the thin oxide layer and then implanting the impurity near an edge of the floating gate. Later steps with heating cause the implanted impurity to diffuse under the floating gate edge. An alternative process first forms a window in the gate oxide layer and implants the impurity through the window. The window is filled with a thin oxide layer and the floating gate is formed so that its edge lies over a portion of the window. Control gates, sources and drains are formed last.
