  • Patent number: 9142013
    Abstract: A substrate storage condition inspecting apparatus includes an illumination device, an imaging device, and a substrate storage condition determining unit. The illumination device includes, on the front side of an opening of a transport container located at an inspecting position, a first illumination portion and a second illumination portion that are spaced apart in the width direction of the opening. The substrate storage condition determining unit detects a pair of high-luminance portions on an inspection image captured by the imaging device, the pair of high-luminance portions being generated in locations circumferentially spaced apart in the peripheral edge portion of the semiconductor substrate by light applied by the first illumination portion and the second illumination portion, and determines whether or not the storage orientation of the semiconductor substrate is abnormal on the basis of the positional correspondence in the vertical direction for the pair of high-luminance portions.

  • Patent number: 7347497
    Abstract: A manipulation device is for wheelchair footrests that have a pair of shafts (8) extending forwards from opposite forward sides of the main frame (2) and a pair of foot plates (9) pivoted at lateral portions to the shafts. This device has manual levers (21) at the forward sides and actuating means (40) that connects the levers (21) to foot plates (9) and consists of a resilient tube (41), a metal wire (42) and a setting retainer (43) for securing the tube to the wire. The tube (41) can elongate in response to an extraordinary tension exceeding a normal stress imparted to said tube, and the wire (42) loosely inserted in the tube (41) can alter an exposed length. An end of each wire (42) is connected to the foot plate (9) at its rear portion located near the shaft (8) pivoting the foot plate. An end of each tube (41) is connected to the manual lever (21) operating to pull up the tube (41) with the wire (42) such that the foot plate (9) rotates and rises to the upright idle position.
