Title: Recovering method for germanium
Inventor: KAKIMOTO NORIHIRO
IPC: C22B41/00
Filed: 1981-02-16
Abstract: PURPOSE: To increase the recovering rate by allowing Ge to be adsorbed in algae cultured in waste water contg. a Ge compound as a culture ground.  
     CONSTITUTION: KOH is added to waste water contg. an org. or inorg. Ge compound to provide strong alkalinity to the liq. unlike general culture conditions. Algae such as Spirulina are culture and grown in the liq. as a culture ground to allow Ge to be absorbed in the algae. Ge is then recovered from the Ge absorbed algae by incineration, extraction or other means.

Title: Thin-film transistor, manufacture of the same, and display device
Inventor: ISHIDA SATOSHI
IPC: H01L21/336
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To provide an active matrix display device capable of preventing lower yield and generation of defective display. SOLUTION: A surface of polycrystalline silicon film 11 becoming an active layer of a TFT(thin-film transistor) 106 is flat, and its thickness corresponding to a drain region 82 and a source region 83 is thicker than the thickness corresponding to a channel region 93. The grain size in every part of the polycrystalline silicon film 11 is nearly uniform and this makes an element characteristic of the TFT106 uniform. This also optimizes a sheet resistance of each region, 82a and 83a, and makes an ON-current of the TFT106 uniform. This resultingly prevents lower yield and generation of defective display.

Title: Object passage detecting sensor
Inventor: KYOMASU MIKIO
IPC: G01V8/20
Filed: 1989-01-30
Abstract: PURPOSE:To eliminate a need of exact adjustment of the light intensity of a light source by detecting passage of an object to be measured based on the deviation of the phase of a signal which is obtained at the time when this object intercepts the light to each photodetector. CONSTITUTION:When an object 13 to be measured passes in front of plural light receiving elements, each light receiving element outputs a signal by light interception due to the object 13. Phases of signals from these light receiving elements are deviated because positions of photodetectors are shifted. A phase comparator 20 detects this phase deviation. Consequently, a user accurately detects passage of the object in accordance with the output of the phase comparator 20. Since the phase deviation is used, it is scarecely necessary to adjust the light intensity of the light source.

IPC: B65H43/08
Filed: 1994-02-18
Abstract: PURPOSE:To correctly detect the distinction between the machine glazed paper and a winding core by fixedly providing a photoelectric detector distinctively detecting the machine glazed paper and the winding core wound with it on a moving member kept in pressure contact with the outer periphery of the machine glazed paper. CONSTITUTION:As the machine glazed paper 2 is extracted by a sheet feed roller, the winding diameter of the machine glazed paper 2 on a winding core 1 gradually becomes smaller. A photoelectric detector 5 on a moving member 4 kept in pressure contact with the machine glazed paper 2 receives the reflected light from the machine glazed paper 2, and it receives the reflected light from the winding core 1 when the machine glazed paper 2 on the winding core 1 is used up. The received light quantity is compared with a set threshold value by a control circuit, and whether the reflected light is received from the machine glazed paper 2 or from the winding core 1 is judged. The light other than the reflected light from the machine glazed paper 2 or the winding core 1 is hardly received, thus the distinction between the machine glazed paper 2 and the winding core 1 can be correctly detected by the photoelectric detector 5 having a small luminescence output.
