Title: Method and device for measuring three-dimensional position on curved surface
Inventor: YAMADA NAOKI
IPC: G01B11/00
Filed: 1993-04-22
Abstract: PURPOSE:To simply and accurately perform, with a video camera, the three-dimensional position measuring of the part on a car body coating surface where a coating flaw is generated. CONSTITUTION:A plurality of point data pieces are selected out of the CAD data for a car body expressed by the object coordinate system SIGMAb, and on the basis thereof the curved surface shape of the coated surface 4 of the car body is expressed as a curved surface approximating formula Eb, which is converted into a video camera coordinate system SIGMAc so that a curved surface approximating formula Ec is obtained. On the other hand, a line-of-view equation Ee expressing a straight line passing a coating flaw generation part Pd in the video camera coordinate system SIGMAc is calculated from the picture element position of the flaw generation part Pd on the image receiving screen of a video camera 16. Then the curved surface approximating formula and line-of-view equation Ee are solved as simultaneous equation so that the coordinates in the video camera coordinate system SIGMAc of the part Pd are calculated as the point of intersection, and the three-dimensional position measuring of the part Pd is conducted by converting the obtained coordinates into the coordinate system SIGMAw of the space to be measured.

Title: Slab with curved end
Inventor: HIRAMATSU TERUO
IPC: B21B1/00
Filed: 1979-07-27
Abstract: PURPOSE:To make the breadth of the slab after the roughing pass uniform, and to prevent the decline of the product yield, by giving the slab end before being fed to the broadside rolling pass the specified curvature in order to make the slab breadth narrow. CONSTITUTION:By previously giving the end part 1 the curvature as shown in the figure A, the breadth of slab B is narrowed to the specified breadth; this slab S is fitted into the edger roll (e) as shown in the figure B. At this point of time, the correction of breadth of the end part 1 is not performed. Next, the broadside rolling work is applied over the taper part 3 to the middle part 2 successively; with the progress of this rolling pass, the excess metal caused by the broadside rolling work is formed into the dog bone 4 along the side edge. Accordingly, the broadside rolled slab possesses the curved part at the end part 1 and the dog 4 at the middle part 3 (as shown in figure C). As a result, at the flat rolling pass shown in figure D, the slab is rolled into uniform breadth possessing no thickness deviation over whole length, so that the trimming of the end part of the product becomes unnecessary as shown in figure E.

CONSTITUTION:A large quantity of semiconductor crystal fine wafers 21 are housed in a container 13 having opening parts 11 smaller than the wafers 21 in its wall surface 12 and the container 13 and all are dipped into an etching liquid 15 in a liquid tank. The container 13 or the liquid tank 14 is rotated and the wafers 21 in the container 13 are etched. It is desirable that the numerical aperture of each opening part 11 is 5% or more from the viewpoint of a uniformity of etching and an exhaust of the etching liquid subsequent to the etching and it is desirable that the speed of rotation of the container 13 is 5 to 30rpm from a respect of the recovery percentage of the wafers. In this case, the wafers 21 or the liquid 15 are/is rotated and the fine wafers are further etched uniformly. Thereby, even if unnecessary fine wafers are generated in a large quantity, these wafers can be effectively utilized without decreasing the recovery percentage.

Title: Method of starting water turbine
Inventor: OKUMURA HIROSHI
IPC: F03B15/04
Filed: 1981-06-24
Abstract: PURPOSE:To enable to start a water turbine safely, by minimizing the time required for oscillation frequency to pass through a critical resonance zone, and thereby eliminating possiblity of causing resonance of the water turbine. CONSTITUTION:When starting instruction is given, a by-pass valve 8, a down stream seal ring 9 and a main valve 7 of the inlet valve are opened in this  order, and guide vanes 4 are kept once at the no-load opening. With opening of  the guide vanes 4, the speed of rotation of the runner 1 is increased gradually.  Here, since the opening angle of the guide vanes 4 is fixed, runner accelerating  torque is reduced gradually as the speed of rotation of the runner 1 is raised, so that the rate of speed change with time is lowered with time. In this connection,  a tolerable minimum rate of speed change with time is predetermined in consideration of the time required to pass through a critical resonance zone, and the  guide vanes 4 are opened to a great angle when it is detected that the rate of  speed change with time has becomes lower than said predetermined minimum  value. By employing such an arrangement, it is enabled to make the oscillation frequency pass through the critical resonance zone promptly.

Title: Photoelectric transducer
Inventor: MIYAJI KENJI
IPC: H01L31/04
Filed: 1991-04-26
Abstract: PURPOSE:To make an open end voltage higher and improve a photoelectric conversion efficiency so as to obtain an amorphous solar cell having a high capacity by applying to a conductive thin film a semiconductor thin film which has the crystalline property in the extra thin film state. CONSTITUTION:Two processings, i.e., a thin film formation under the process of irradiating ions on a generating surface and ion irradiation only, are repeated alternately to form a thin film of 1 to 100Angstrom  in thickness per one cycle, resulting in a photoelectric transducer having a crystalline semiconductor thin film of less than 300Angstrom  in total thickness. Therefore, this crystalline semiconductor thin film formation can realize the film thickness of less than 300Angstrom  which has not been reached by the conventional techniques, so that an open end voltage and photoelectric conversion efficiency can be improved by applying these semiconductor thin films to the conductive thin films comprising an amorphous solar cell.

Title: Flexible film dam
Inventor: MURAMATSU TAKEO
IPC: E02B7/20
Filed: 1985-05-09
Abstract: PURPOSE:To keep the water level of upstream constant all the time without the needs for man-power energy by a method in which water lifted by a pump to be driven by natural solar forces is sent through a water supply tube into a dam, and a drain valve is opened or closed according to the water level of upstream. CONSTITUTION:Whenever power is supplied from a solar cell 7, operations are performed regardless of the operations of an underwater pump 6 and the dam body 2. When water level in a water supply tube 3 reaches a given one H2, the internal pressure of the dam body 2 is kept constant. When river water is raised to a given water level at which the dam body 2 is fallen down, a rope 15 is tensed by the buoyancy of a float 14, and a drain valve 13 is opened. When the water level of upstream is lowered, the float 14 is loosened, the valve 13 is closed to stop water draining, and the dam body 2 is again raised by supply of water from the tube 3. The needs to feed a power source medium to the dam-setting site can thus be eliminated, and the internal pressure of the dam body can be kept constant to prevent the occurrence of excessive pressures.

Title: Control system for image display device and control method for image display system
Inventor: MORI MAKIKO
IPC: H04N5/44
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To easily adapt an image display part to be connected even if its characteristics change by providing in the image display part with a specific information transmitting means which transmits specification information specifying the characteristics of its device to a supply source and a display part communication means which communicates a signal including a video signal determined by a determining means for the supply source.

If the display part is not known and a standard monitor is not connected either, a specification request command is sent to the image display part 1. Once specification information is received from the image display part 1, it is stored in a nonvolatile memory on condition that it is applicable to its terminal part 2. Then the image display part 1 is requested to transmit necessary adjustment data according to selected specifications. On receiving the adjustment data, the specifications of the image display part 1 can be grasped, so normal processes begin.
