Abstract:
A rigid-flex PCB includes at least one rigid PCB (RPCB) and at least one flexible PCB (FPCB). Each RPCB has a connection section; first and second sections separately extended from two lateral edges of the connection section and having at least one FPCB bonding side each; and a weakening structure formed along each joint of the connection section and the first and second sections. Each FPCB has a bending section corresponding to the connection section on the RPCB; first and second sections separately extended from two lateral edges of the bending section and having at least one RPCB bonding side each corresponding to the FPCB bonding sides of the first and second sections of the RPCB. When a proper pressure is applied against the weakening structures, the RPCB may be easily bent broken at the weakening structures to remove the connection section therefrom.
Abstract:
The present invention relates to a gas filtering-buffering device, which comprises at least one gas filtering unit; a gas inlet, the gas to be processed flows into the at least one gas filtering unit from the gas inlet; and a gas outlet, the gas processed by the at least one gas filtering unit is discharged out of the at least one gas filtering unit via the gas outlet, wherein the at least one gas filtering unit comprising: a gas buffering cavity for performing buffering function for the gas, and a gas filtering part for performing filtering function for the gas. In the present invention, it is not only provided with a gas filtering part which is able to filter the moisture and organic substance in the gas, but also provided with a gas buffering cavity, which integrate the filtering and buffering functions together. The buffering cavity may expand the capacity and stabilize the pressure of the gas, and balance the concentration, pressure and flow rate of the gas, it is advantageous to reduce the on-way pressure lost and partially pressure lost, decrease fluctuation of the flow current and the pressure thus, the detecting performance of the detector is improved.
Abstract:
An improved method of reducing wear dust and torque required to turn a multi-port rotary disc valve utilizes a thrust bearing to hold the valve seat and/or valve disc such that they are not in contact with each other, or have light contact each other.

Abstract:
A multi valve two-stage pulse tube type GM refrigerator having a rotary valve that comprises one track for flow to the regenerator and two tracks for flow to the pulse tubes where the valve has two high pressure ports to the pulse tubes located on a single track and two low pressure ports from the pulse tubes located on a separate single track and where there are two cooling cycles per revolution of the rotary face valve.
Abstract:
By understanding a website author's intention through an analysis of the function of a website, website content can be adapted for presentation or rendering in a manner that more closely appreciates and respects the function behind the website. A website's function is analyzed so that its content can be adapted to different client environments. A function-based object model (FOM) identifies objects associated with a website, and analyzes those objects in terms of their functions. Desktop oriented websites are adapted for mobile devices based on the FOM and on a mobile control intermediary language.
Abstract:
A chemical processing bath and system used in semiconductor manufacturing utilizes a dynamic spiking model that essentially constantly monitors chemical concentration in the processing bath and adds fresh chemical on a regular basis to maintain chemical concentrations at desirable levels. Etch rates and etch selectivities are maintained at desirable levels and contamination from undesirable precipitation is avoided. The system and method automatically compare concentration levels to a plurality of control limits associated with various technologies and identify the technology or technologies that may undergo processing.
Abstract:
A chuck is provided with a body, a plurality of jaws and an adjustment ring. The adjustment ring is threadably engaged with the jaws. When the adjustment ring is rotated in one direction, the jaws tighten by moving closer to each other. When the adjustment ring is rotated in the opposite direction, the jaws loosen by moving away from each other. An impact member is also provided for engagement with the adjustment ring. When the drive shaft of the power tool is rotated, the adjustment ring impacts against the impact member. As a result, the adjustment ring and the body of the chuck rotate relative to each other causing the jaws of the chuck to loosen or tighten depending on the direction the drive shaft is rotating.
Abstract:
A housing (10) is applied to an electronic device. The housing includes a transparent base (12) and a first metal coating (14). The base contains a first surface (122). The first metal coating is formed on the first surface of the base. A plurality of first through holes (142) is defined in the metal coating. The first through holes are in an arrayed pattern.
