Title: Automatic sheet material feeder
Inventor: ONODA KIYOMI
IPC: B65H1/06
Filed: 1982-09-21
Abstract: PURPOSE:To separate and feed sheet materials of various qualities sheet by sheet without jamming and multi-feeding by varying the pressing force of a friction member to a paper feed roller in an automatic sheet material feeder. CONSTITUTION:A user changes and control the amount of projecting an adjuster 8 from the outside of an apparatus corresponding to the quality (thickness, firmness and roughness of the sheet surface) of a sheet material 1, so that the pressing force of a friction member 6 to a paper feed roller 5 is adjusted to the quality of various sheet materials. Thus, the sheet materials 1 of various qualities can be separated and fed out sheet by sheet without jamming and multi- feeding.

Title: Method for resetting to original point for robot
Inventor: NISHI YOZO
IPC: B25J9/10
Filed: 1985-07-24
Abstract: PURPOSE:To enable both upper and lower arms to be reset to each proper original point by driving the lower arm toward its original point while driving the upper arm so that the relative angle between both arms is kept constant in case the upper arm reaches it original point earlier than the lower arm. CONSTITUTION:When an upper arm 1 is moved to its original point, it is decided whether a lower arm 2 is set at its original point or not. If the arm 2 is not set at its original point, the arm 2 is moved toward its original point direction B while driving the arm 1 so that the relative angle between both arms 1 and 2 is kept constant. In other words, the relative angle theta is decreased by DELTAthetaas shown by the alternate long and short dash line when only the arm 2 is turned toward B by an angle DELTAtheta. Thus the arm 1 is shifted from its original point. In order to avoid this shift, the arm 1 is turned counterclockwise by the angle change DELTAtheta of the arm 2. As a result, the relative angle theta between both arms is always kept at theta0 regardless of the angle change of the arm 2. Then the arm 1 is kept at its original point until the arm 2 is reset to its original point.

Title: Production of rubber stamp
Inventor: NAGATANI TADAO
IPC: B41C3/04
Filed: 1981-10-12
Abstract: PURPOSE:To obtain a rubber stamp such as one for New Year's cards which is excellent in adhesion of an ink to a stamp surface, by a method wherein a plate form rubber stamp blank material provided with a rugged pattern on a surface thereof is molded by a metallic mold, thereafter projected surfaces of the blank material are efficiently roughened by blasting a particulate material against the surface of the blank material. CONSTITUTION:After a plate form rubber stamp blank material 1 provided with a rugged pattern on the surface thereof is molded by a metallic mold, particulate material 4 (e.g., sand grains, iron particles) is blasted against the surface of the blank material 1, so that the projected surfaces 2 are converted into roughened surfaces having minute ruggedness, and a rubber stamp excellent in adhesion of an ink is produced. The particulate material 4 is preferably blasted, for example, from the ejecting pipe 3 of a sand blasting machine in the form of a jet by using compressed air. EFFECT:Since the projected surfaces 2 brought into direct contact with a paper surface are minutely roughened, the ink is prevented from being repelled in the form of spherical particles due to surface tension.
