  • Patent number: 9752866
    Abstract: A measurement system is configured to measure a surface structure of a sample. The surface of the sample has a thin film and a via, the depth of the via is larger than the thickness of the thin film. The measurement system includes a light source, a first light splitter, a first aperture stop, a lens assembly, a second aperture stop, a spectrum analyzer and an analysis module. The first light splitter disposed in the light emitting direction of the light source. The first aperture stop disposed between the light source and the first light splitter. The lens assembly is disposed between the first light splitter and the sample. The second aperture stop is disposed between the lens assembly and the first light splitter. The spectrum analyzer is disposed to at a side of the first light splitter opposite to the sample.

  • Patent number: 7431613
    Abstract: The present invention provides an electronic charging cup assembly, including an electronic charging cup and charging cup holder. The electronic charging cup is provided with an embedded cell module and a button set, so that the cell module supplies sufficient power to the linear conducting strip covering the cup core. Since the cell module is a rechargeable cell structure, it is only required to place the electronic charging cup into the charging cup holder in the event of electric exhaustion of cell module, thereby achieving the purpose of additional power supply with improved applicability.

  • Patent number: 5649607
    Abstract: An escape assembly has two rows of parallel slide frames positioned on an outer wall. A curved slip frame connects to a last slide frame of each row of parallel slide frames. A slide rail connects to each slide frame. Each slide frames has an H-shaped middle frame connecting to two U-shaped side frames. A slide way is formed in the middle frame. A slide passage is formed between two side frames. The middle frame has two positioning plates. Each side frame has spaced retarding blocks therein. The side frame has a notch thereon. One end of the slide rail is fastened on the side frame. The escape device has a transverse rod, two triangular blocks, two wheels, two parallel longitudinal belts, two loops and a transverse belt with a fastening device thereon. Each end of the transverse rod has a wheel abutting a triangular block. Two rings are disposed beneath the transverse rod. Each ring connects to a longitudinal belt. A loop is disposed at an end of each longitudinal belt.
