Title: Electroless plating method of thermoelectric semiconductor
Inventor: KATO SEIKI
IPC: H01L35/34
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To make a plating film on thermoelectric semiconductor uniform.

After that, the bogie 10 is moved to a standby position to rotate a main arm 12 by 1/3 and a new sleeve for changing use is stopped in a delivering position. If the main arm 21 is rotated clockwise by Po, an intermediate gear 26c is rotated clockwise by P1 and a planetary gear 26b is rotated counterclockwise by Q since a sun gear 26a is fixed. Since the diameter of the pitch circle of the gear is the same diameter, the receiving claw 25 always moves in parallel at same attitude in the direction of horizontally projecting.

Title: Image inputting device
Inventor: HABA YOSHIHITO
IPC: H04N17/02
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To eliminate a write box, a vector scope, a waveform monitor, etc., by performing image adjustment, photographing a test image that is shown on a computer display part. SOLUTION: For hue adjustment, a camera part 1 picks up the image of a test video window for display on a VGA monitor 4. In such cases, places both near and far of the part 1 and the monitor 4 are adjusted so that only a color bar may be shown on an image display window. When amplitude and phase do not stay within a regulation range where each color signal makes a vector scope ideal value as a center, a host part 3 sends a hue adjustment command to an image processing part 2 to perform hue adjustment so that they can stay inside the regulation range. Also, for luminance adjustment, far and near adjustment of the part 1 and the monitor 4 are performed so that only 5600K white image may be shown on the image display window.  When waveform monitor window display luminance does not stay inside the regulation range of a white uppermost position, the part 3 sends a luminance adjustment command to the part 2 and performs luminance adjustment.

Abstract: PROBLEM TO BE SOLVED: To provide a method executed without depending upon the technique of a skill worker to restore the recess and the defect of a part in a further complicated shape than those of a corner part and other plane part to an original shape by putty, in repair of a car body. SOLUTION: In a method wherein the shape of the recessed part or the defective part of a car body is restored to an original shape by piling up putty, a thermoplastic resin lump in an amount enough to allow covering of other car body part is heated to temperature higher than a softening point of resin and pressed against other car body part formed in the same surface shape as the original shape of the recessed part or the defective part. A contact part therebetween is plastically deformed in a manner that the surface shape of the contact part coincides with that of other car body part and this state is held. With this state, cooling as it is effected for curing and this way effects making template of the surface shape of car body part.  By pressing the obtained template against putty before curing piled up on the recessed part or the defective part in an amount enough to allow restoration of the recessed part or the defective part, the surface shape of the putty coincides with the template. The template is held until the putty is cured to hardness high enough to maintain the shape by itself and thereafter the template is removed.
