Abstract: An addition system of a reducing agent in a semiconductor manufacturing process includes pre-treatment and post-treatment gas concentration detection devices, a process exhaust gas treatment device, a reducing agent supply device, and an addition system control device. The process exhaust gas treatment device purifies exhaust gas of a semiconductor manufacturing process and emits a post-treatment gas. The reducing agent supply device supplies a reducing agent gas into the process exhaust gas treatment device. The post-treatment gas concentration detection device detects a residual concentration of the reducing agent gas in the post-treatment gas. The addition system control device calculates destruction and removal efficiency (DRE) for process gases according to pre-treatment and post-treatment gas concentrations, and, according to the DRE and the residual concentration, sends a signal to the reducing agent supply device to control the amount of the reducing agent gas added.

Abstract: An eyeglasses enabling quick exchange of lenses is provided, in which the lower frame thereof mainly has two lens mounting apertures respectively provided at two sides for mounting lenses. First pivot connectors are provided at middle portion of the lower frame. A fastening member has second pivot connectors which are pivotally connected with the first pivot connectors. A snap-fit hook is provided on the upper end of the fastening member. An upper frame is to be fitted on the upper edge of the lower frame by fastening its two assembly portions provided at both sides of the upper frame to both sides of the lower frame. The upper frame has a snap-fit recess corresponding to the snap-fit hook provided at the middle portion thereof By turning the snap-fit hook upward or downward, the exchange of lenses can be easily conducted without using any tool for disassembly.

Abstract: An eyeglasses assembly structure is provided, in which assembly slots for joint members are mainly formed on both sides of the eyeglasses frame, and the joint members are pivotally connected therein. Locating members are respectively interposed between upper and lower elastic elements for holding the pivotal connection status of the joint members and the assembly slots. When the joint members are to be detached from the assembly slots, the locating members are pushed into sliding grooves of the joint members, and the upper and the lower elastic elements are pressed to be deflected inward so as to allow the upper and the lower pivots detached from the pivotal connection with the assembly slots. Therefore, temples or strap can be assembled on the rear ends of the joint members and then the eyeglasses patterns can be conveniently transformed according to users' needs.
