Abstract:
Electroplating of aluminum may be utilized to form electrodes for solar cells. In contrast to expensive silver electrodes, aluminum allows for reduced cell cost and addresses the problem of material scarcity. In contrast to copper electrodes which typically require barrier layers, aluminum allows for simplified cell structures and fabrication steps. In the solar cells, point contacts may be utilized in the backside electrodes for increased efficiency. Solar cells formed in accordance with the present disclosure enable large-scale and cost-effective deployment of solar photovoltaic systems.

Abstract:
A welding system for automatically welding a welding seam includes a welding arm, a sensor and a controller. The controller includes a welding seam contour detection component, a welding seam contour calculation component, a welding trajectory point calculation component, and a welding parameter setting component. The welding seam contour detection component is used for detecting an initial welding seam contour and detecting remaining welding seam contours after welding each layer of the welding seam. The welding seam contour calculation component is used for calculating the detected welding seam contours. The welding trajectory point calculation component is used for calculating welding trajectory points based on the calculated welding seam contours. The welding parameter setting component is used for setting welding parameters based on the calculated welding seam contours and the calculated welding trajectory points.

Abstract:
A method of making a porous bushing for an impeller shaft of a heat dissipation fan, includes: compacting a porous body-forming material in a mold to form a green body that has a shape conforming to the porous bushing; and sintering the green body to form the porous bushing. A heat dissipating fan incorporating the porous bushing is also disclosed.
Abstract:
The present invention discloses a dual color molding apparatus for a measuring tape and its molding method, and a dual color plastic technology is used to replace the existing label and decoration such as a label on the measuring tape and provide a different design of words, numbers or logos on a concave and convex surface to facilitate users to identify the molding apparatus. The molding apparatus includes a male mold fixing base, a first male mold, a second male mold, a female mold fixing base, a first female mold, a second female mold, a central axle and a middle plate. The first female mold forms a first cavity with any one of the male molds, and the second female mold forms a second cavity with any one of the male molds, and a glue injection is performed in the first cavity and the second cavity by a first glue injection unit and a second glue injection unit respectively. The first female mold and the second female mold are coupled to the female mold fixing base, and the first male mold is installed above a first male mold insert fixing base of the male mold fixing base, and the second male mold is installed above a second male mold insert fixing base of the male mold fixing base, and both first male mold and second male mold are coupled to the middle plate, and the first male mold is rotatably installed at the top of the second male mold insert fixing base and the second male mold is rotatably installed at the top of the first male mold insert fixing base through the central axle connected to the middle plate. Therefore, a dual color glue injection can be completed for the dual color mold without replacing the molding apparatus.
Abstract:
A personal routine system that automatically traces and links a users' time, locations and activities. The person routine system includes a position recording unit for recording the user's location information, a routine tracking system having a first mapping module for matching data and files the data with the user's time and location information, and a service platform. The routine tracking system also provides a browse function and a search function for the matched records and transfers them to the service platform. The service platform stores the records transmitted from a second network interface into a second storage unit and uses a user interface to display the records stored in the second storage unit and further provides the browse and search functions.
Abstract:
An art design knife structure that includes a case, the case including a left case half and a right case half that are assembled together, a blade frame capable of sliding back and forth disposed within the interior section of the case, and a push button sleeved onto the upper edge at the tail end of the blade frame. The push button projects through a slot hole in the case and, furthermore, the push button consists of two perpendicularly and individually disposed L-shaped push blocks, while the push button is capable of rotating 90 degrees. As such, when cutting objects from the left or the right, the angle and orientation is selectable by an optimal push button direction, the structure of present invention thereby increasing art design knife utility and, furthermore, enhancing their industrial practical value.
Abstract:
A magnetic recording medium having at least an adjustable magnetic property is provided. The provided magnetic recording medium includes a substrate and a layer sequence located thereon. The layer sequence includes a underlayer, a buffer layer and a recording layer made of a magnetic material. According to the present invention, the adjustable magnetic property of the magnetic recording medium is adjusted via the variation of the thickness of the underlayer.
Abstract:
A telephone device 100, integrated with a telephone or as a telephone add-on device, improves receipt and processing of network information such as Caller ID from conventional telephone networks. A comparator 103 decodes incoming Frequency Shifted Keying (FSK) signals by transforming transform the FSK signal into a square wave signal with corresponding periodic pulse widths. The transformed signal is sent to a microcontroller 105. The microcontroller is preprogrammed to further decode the transformed signal to obtain digital data representative of Caller ID information. Multiple devices connected to the same telephone line 410 may receive off-hook Caller ID simultaneously by selective disablement of an acknowledgment tone transmission through use of a switch 440. Configurable function keys 471 on a user interface 430 controls other network services, such as voice mail, regardless of different command code formats utilized by various network service providers. By grouping and selecting network service command codes, a user can automatically configure a telephone device to interact with the selected network service provider.
