Abstract: A method of testing a test wafer includes shielding test centers on a test wafer using shielding tabs during the deposition of a layer. The test wafer has the same size and shape of product wafers. The shielding tabs are then removed from the test wafer. A plurality of predetermined points which are separated from each test center by a critical interval are checked, and whether each point is covered by the layer is determined through an interferometer or a microprobe. The test wafer is processed after adjustments to or maintenance on equipment, or after a fixed number of product wafers have been processed.

Abstract: A portable bicycle comprises a front bar having a front end coupled to a head tube, a rear frame section including a lower seat tube extended upwardly from a bottom bracket, a upper seat tube spaced and aligned with the lower seat tube, and a hollow rear bar for slidably receiving the front bar, the rear bar being intersected the upper and lower seat tubes, and a fastening mechanism for securing the front bar to the rear bar. Detaching a seat post and a saddle, unfastening the fastening mechanism, fully projecting the front bar from a rear opening of the rear bar, and fastening the fastening mechanism will shorten the distance between front and rear wheels to a minimum and facilitate the bicycle to store or carry in a much reduced size.

Abstract: The present invention relates to a phosphorus-containing epoxy resin, which is an epoxy resin modified with a side chain having a reactive phosphorus-containing compound. Also, the present invention relates to a flame-retardant resin composition, which comprises: (1) the phosphorus-containing epoxy resin, (2) a halogen-free hardener having a reactive hydrogen capable of reacting with the epoxy group in epoxy resin, and (3) a hardener promoter. The flame-retardant resin composition described above has improved excellent heat resistance and flame retardant property, and is especially suitable for adhesive laminates, composite materials, printed circuit boards, adhesive material for copper foils, and is suitable for IC packaging materials.

Abstract: The present invention relates to a comfortable shoe structure capable of preventing relative displacement between the shoe pad and the shoe, so as to make the walk comfortable. The shoe structure includes: a sole assembly comprising a big sole and a mid sole integrally formed with the big sole; at least a comfortable block fixed between the big shoe and the mid shoe and partially protruded out of the mid shoe; a vamp, a lower edge of which located between the big sole and the mid shoe.

Abstract: A stretching bicycle comprises a front frame section having a hollow front bar as a portion of crossbar, a rear frame section having a hollow rear bar for slidably receiving the front bar, the front and rear bars being disposed in a straight line not aligned with the front and rear wheels, and fastening means for securing the front and rear bars together at a front opening and a rear opening of the rear bar respectively. The bicycle has the advantages of adjusting length for accommodating users of different body heights in use, saving storage space after disassembly, and being structurally strong and lightweight.
