Title: Automatic classification system in recycling waste plastic containers
Inventor: HUNG SHIOU-WAN
IPC: B07C5/00
Filed: 1999-05-14
Granted: 2002-01-11
Abstract: The present invention relates to an automatic classification system in recycling waste plastic containers. At present, the classification of waste plastic containers is done manually. This type of manual classification is not accurate and the plastic containers can not be classified reliably. As a result, the products of recycled plastics have a poor quality and the profit of the recycling process is low. The automatic classification system in recycling waste plastic containers according to the present invention comprises: an identification bar code, a bar code classification regulation, and a bar code identification device. Such a system of classification by using machines can accurately classify the plastic containers and increase the recycling rate of the plastic containers.

Title: Method for promoting generation of hydrogen from biological sludge by heat pretreatment
Inventor: LIN CHIOU-YU
IPC: C01B3/02
Filed: 1999-12-29
Granted: 2003-09-21
Abstract: The anaerobic decomposition of an organic material can generate hydrogen. The combustion of hydrogen will not generate a green house effect gas. Therefore, hydrogen can be used as an important future energy. Clostridium is an important bacterium for generation of hydrogen in waste water sludge and mainly exists in a spore state. Heating can inhibit the propagation of methane formation bacteria in waste water sludge and promote the propagation of hydrogen-generation bacteria. Therefore, heating can promptly obtain hydrogen-generation bacteria having a better activity. Furthermore, the anaerobic decomposition of hydrogen-generation bacteria can be used to produce hydrogen from an organic waste water sludge.

Abstract: The present invention relates to double access and sculpture processes for printed circuits with single copper layer. The structure is similar to single side printed circuits, but this invention can access both sides of the copper layer without the expensive traditional precision punching hole techniques such as laser punching to avoid punching through the copper layer. Moreover, it can reduce the cost of printed circuits material with less weight and size as compared that of double side printed circuits. This invention of double access and sculpture processes mainly consists of (1) the pre-pressed procedure is needed before laminating the first punched cover layer and a punched copper layer to form a copper clad laminated layer. It is also needed before laminating the second cover layer with a copper clad laminated layer. This procedure is aimed to avoid generating the air bubble or misalignment during laminating procedure. (2) Applying anti-over-etching material procedure is added to prevent the copper from over-etching, because the contact area between the first cover layer and the copper layer can easily generate air bubble to cause over-etching the copper. (3) Adjusting suitable temperature and pressure is needed during laminating procedure to reduce the deformation of material or misalignment.
