Abstract: A stripping tool for an armor-wrapped cable is provided, which includes a first handle and a second handle. The first handle includes a cutting portion, a pivoting portion and a gripping portion. The second handle includes a clamping portion, a pivoting portion and a gripping portion. The first handle and the second handle are pivotally connected at the pivoting portion of the first handle and the pivoting portion of the second handle, so that the user can pivot the second handle relative to the first handle by holding the gripping portion of the first handle and the gripping portion of the second handle, so as to clamp the armor-wrapped cable between the cutting portion of the first handle and the clamping portion of the second handle, and cut the cable by the cutting portion of the first handle.

Abstract: A powered cutting tool for cutting tubular or cylindrical workpieces such as pipe is described. The cutting tool includes a base, an electric motor, a collection of rollers, a frame, a feedscrew, an auto cut wheel system, and a handle for rotating the feedscrew and adjusting the position of the auto cut wheel system relative to the rollers. In certain versions, the cutting tool includes torque-limiting provisions, to limit the amount of torque applied to the feedscrew. In certain versions, the cutting tool includes rollers and press wheels featuring non-metal outer surfaces.

Abstract: Various surface cam planetary mechanisms are described that convert rotational motion to linear reciprocating motion. Also described are assemblies using such mechanisms such as pump drives. A surface cam component used in the mechanisms includes a cam race that exhibits an undulating surface.

Abstract: An energy economizing combination includes a switch device coupled to an energy output unit, an energy discharging device coupled to the switch device for energy dissipating purposes, and one or more energy units coupled to the switch device, for selectively receiving energy from the energy output unit. The energy unit includes a switch member coupled to the switch device, and a load facility coupled to the switch member, for being controlled by the switch member. The energy unit includes two pipings coupled between the switch member and the load facility. A heat reservoir and a cold reservoir may further be coupled to the switch device, for receiving and storing cold energy.

Abstract: The invention provides a voltage-multiplier circuit, and comprises a voltage-pumping block and a functional generator. The voltage-pumping block is composed of a first diode, a second diode, a first couple capacitor, a second couple capacitor to pump an input voltage. The invention can form the multi-level voltage-pumping blocks, and the voltage-pumping block is only needed to replace the diode and the capacitor to repair and increase/decrease the numbers of the diodes and the capacitors to achieve easily adjust the range of the voltage-pumping to achieve the object of decreasing the time and costing saving.

Abstract: The present invention relates to a cap structure for a container outlet, which comprises a cap body and a separating blocker, wherein the top side of said cap body is contrived into closed plate, and its bottom side is contrived into vent opening, a lateral side links top side and bottom side such as being surrounded as an unitary body; a hollow compartment is created in said internal round top of said cap body, and a hollow cap linking channel is formed near the other end of said bottom side, and said separating blocker is inserted at the joint of said hollow compartment in said cap body and said cap linking channel, its top side faces said hollow compartment, and its bottom side faces said cap linking channel. Any granule solid or liquid material being stuffed in said hollow compartment in said cap body can be separated and blocked from leaking, if said separating blocker is inserted in duly position.

Abstract: A digital frequency-hopping (FH) transceiver and a method thereof, which can be applied to FH communication system with a short FH time, are disclosed. The transceiver employs a digital signal processing (DSP) in baseband (BB) circuits to implement FH without need to adjusting the RF carrier frequency. Wherein, the digital FH transmitter performs DSP on a digital BB transmission signal to frequency-hop between BB sub-bands corresponding to sub-bands of a channel, converts it into an analog signal, and then modulates the analog signal to the channel sub-bands for transmission. The digital FH receiver then performs carrier demodulation, analog-to-digital conversion and DSP on a received signal to regain the original digital BB transmission signal.

Abstract: A method for forming a contact window is provided. First, a substrate is provided. On the substrate a dielectric layer is formed. Then, the dielectric layer is etched to form an opening, which defines a sidewall. Afterwards, on the sidewalls a low leakage dielectric isolation layer is formed. Finally, a contact window is formed by etching the substrate through the opening.
