A crank cover assembly for a bicycle which includes a molded shell member and a molded leaf member which cooperatively encase a forged crank of a bicycle. The molded shell and molded leaf are configured to substantially perform to the outer contour of the forged crank, and each has formed therethrough openings substantially aligned with through openings in the forged crank. The shell and leaf members are coupled together by use of fastening mechanisms such as a catch-tongue joint or a hot-melted joint.

A control method for a TV system is provided. The TV system has a digital signal port connected to a player. The control method includes the following steps. After the TV system is turned on, a first set value is written into an EDID rewritable memory of the TV system. After the player is connected to the TV system, the TV system judges whether a quality of the first digital signal group is good or bad. If the quality of the first digital signal group is good, a video/audio signal is issued by the TV system according to the first digital signal group. Whereas, if the quality of the first digital signal group is bad, a second set value is written into the EDID rewritable memory.

A source driving circuit is provided. The source driving circuit includes a plurality of source drivers, first switches, and second switches. Each transmission line of each source driver is coupled to the first switch and the second switch. In a first period, the first switches are turned on, and the source drivers generate a first driving signal to drive pixels in odd columns of a display panel through the transmission lines and the first switches. In a second period, the second switches are turned on, and the source drivers generate a second driving signal to drive pixels in even columns of the display panel through the transmission lines and the second switches. Therefore, the problem of the prior art that each transmission line of the source driver drives pixels in only one column of the display panel is improved and the hardware cost is greatly decreased.

A bottom bracket bearing for a bicycle is provided which includes an axle, a pair of ball bearings, a flanged cup, and an adjusting cup disposed within a five-way tube. The axle has a reducing quadrangle extending from both ends thereof, and a continuation area between the quadrangle portion an a cylindrical portion of the axle, and has a flat circular flange formed adjacent the cylindrical portion. A joint-packing is positioned against the flat circular flange, the thickness of the joint-packing extending at least 1 mm beyond the flat end of the flanged cup, thereby substantially preventing the crank with the chain wheels from contacting the flanged cup.

A system for displaying images including a display panel and a fabrication method thereof are provided. The method includes forming a first gate line and a second gate line at each row of pixels of the display panel, wherein the first gate lines and the second gate lines are separated and electrically isolated from each other. A first insulating layer is formed to cover the first gate lines and the second gate lines, and a plurality of via holes are formed in the first insulating layer to expose the first gate lines and the second gate lines. Then, a first conductive pattern is formed on the first insulating layer, such that the first gate line at each row of the pixels is electrically connected to the second gate line at an adjacent row of the pixels, by the first conductive pattern, through the via holes.

A power supply unit provides a voltage, and a driving current to a series of light emitting diodes. A dimming unit adjusts a duty cycle of an original dimming signal to generate a dimming signal according to the driving current and an ideal current. A current sink coupled to the series of light emitting diodes adjusts a duty cycle of the driving current according to the dimming signal.

A distribution layer of silicon quantum dots are fabricated. After the layer is exposed to sun light for a while, the layer absorbs energy and produces pairs of electron and hole. By limiting the movement of the electrons and their moving directions through the structure obtained, the efficiency of an optoelectronic conversion is enhanced.
摘要:
A semiconductor device is constructed of at least one indium nitride or indium nitride alloy nanostructure on a substrate or other thing film layer. The method used to create the semiconductor device involves illuminating the substrate with a lateral intensity patterning of ultraviolet light in the presence of at least hydrazoic acid and a compound containing indium gas flows. Additionally, a semiconductor light-emitting/detecting modulating device composed of at least one indium nitride or indium nitride alloy nanostructure. The method used to create the semiconductor light-emitting/detecting modulating device involves embedding at least one nanostructure in the interior layer of the device. Further, a monolithic photovoltaic-photoelectrochemical device where one layer is composed of an indium nitride or indium nitride alloy film or nanostructure.

The present invention provides a mean axis of bicycle, which includes a five-way pipe, an internal pipe, an axle, two setting rings, two ball housings and two ball bearings. Wherein the inside walls at both ends of the internal pipe and the outside walls of the two ball housings are turned threads separately, and one ball housing has a ring shoulder at the middle position of the thread. Thereby the two ball housings fixed one ball bearing, the axle and another ball bearing in the internal pipe respectively with the outside threads to form a mean axis assembly. Then the two setting rings fix the mean axis assembly in the five-way pipe from both sides by connecting to the ball housings of the mean axis assembly in thread joint, and to the five-way pipe in bell and spigot joint. When turning the setting rings in or out from both sides of the five-way pipe, the axle in the mean axis assembly can be moved from the right to left or from the left to right along the axis to make the master chain wheel set keep in an allowable range with the rare sprocket set.
