A building-block-combined-type high power transformer includes a first iron core body contacting a second iron core body, a plurality of plate bodies, and a plurality of isolating bodies. The first iron core body and the second iron core body have a first side wing part and a second side wing part respectively at both sides thereof. Both the first side wing part and the second side wing part respectively have a first open channel and a second open channel formed there between. Each of the plate bodies is positioned in both the first open channel and second open channel. Each of the isolating bodies is positioned between first plate bodies and second plate bodies of the plurality of plate bodies. The first side wing part and the second side wing part are inserted through an open hole of corresponding plate bodies and a through hole of corresponding isolating bodies.
Abstract:
A laminar transformer having double-face secondary winding includes a primary winding part and a secondary winding part. The primary winding part further includes an isolating body seat and a plurality of coil sets. The secondary winding part further includes two plate-body set, each being positioned in the containing channel has a plurality of plate bodies and a plurality of insulating bodies. Each of the plate bodies has an opening for containing the central column and a guided channel that being positioned on a side of the opening has on both side thereof a pole lead respectively. The insulating bodies being a ring-shaped structure and being positioned in-between the plate bodies has a through hole for containing the central column. The plurality of plate bodies are laminated alternately and positioned in the central column making each of the plate-body sets form the one with four pole leads.
Abstract:
The invention relates to a chemical etching composition and to methods to produce a photovoltaic cell with transparent regions. The methods comprise a step to locally dispense an etching composition on the photovoltaic cell in a pattern, or adjacent to the edge thereof; an optional step to apply heat to the cell; and a step to remove the etching composition. The methods are further characterized by the chemical removal of one or more chemically distinctive layers of the photovoltaic cell where the etching composition is applied. The methods may be used to produce a thin film photovoltaic panel.
Abstract:
A method for fabricating an image sensor is described. A substrate is provided. Multiple photoresist patterns are formed over the substrate, and then a thermal reflow step is performed to convert the photoresist patterns into multiple microlenses arranged in an array. The focal length of the microlens increases from the center of the array toward the edge of the array.

The method comprises following steps: providing a plurality of chirp JK pairs; detecting the plurality of chirp JK pairs, and loading a power on a terminal resistor of a USB device end of the universal serial bus and its coupled to a terminal resistor of a USB host end of the universal serial bus; detecting a voltage level variation of the chirp JK pair; and processing the online calibration according to the voltage level variation to maintain the voltage level within a preset range.
Abstract:
In an example embodiment, a device for generating a cleaning foam includes a female housing and a male plug. The plug includes an aperture into which a fluid flows from another component of the cleaning system. The plug includes a premix chamber which receives the fluid from the aperture and into which a gas is injected to form a foam. In an example embodiment, the chamber is a hollow cylinder and the gas is injected into the cylinder through channels which are tangential to the cylinder. The plug also includes a solid cylinder with a continuous helical indentation on the outside of the solid cylinder. When the male plug is inserted into the female housing, the continuous helical indentation and the inner surface of the housing form a helical channel through which the foam flows and is further mixed on its way back into the cleaning system.
Abstract:
An expression system for producing a multi-enzyme complex, the system including a nucleic acid molecule containing a promoter operatively linked to a nucleotide sequence including multiple genes encoding multiple enzymes that are components of the multi-enzyme complex.
Abstract:
A wall-following moving device consists of a base; a determining drive unit; multiple collision sensing units; two signal transceiver units arranged at the same lateral side of the base parallel to the moving direction of the base for synchronously transmitting and receiving specific signals, and being electrically connected to the determining drive unit; and a moving element mounted to the base and controlled by the determining drive unit to perform various movements. The determining drive unit compares two reflected signals from a wall received separately by two signal transceiver units, and uses the intensity difference of the signals as a basis to control the moving element to orientate the robot parallel to the wall. By an intricate coordination of the collision sensing units, two signal transceiver units, determining drive unit, and the moving element, the distance between the robot and a wall can be precisely determined and controlled.
Abstract:
The present invention provides a method of thinning a wafer. First, a wafer is provided. The wafer includes an active surface, a back surface and a side surface. The active surface is disposed opposite to the back surface. The side surface is disposed between the active surface and the back surface and encompasses the peripheral of the wafer. Next, a protective structure is formed on the wafer to at least completely cover the side surface. Last, a thinning process is performed upon the wafer from the back surface.
