Title: Position sensor axis and position sensor apparatus
Inventor: MURAKAMI TAKU
IPC: G01B7/00
Filed: 1989-09-28
Abstract: PURPOSE:To detect characteristics of each position for continuously detecting absolute positions by placing an alteration pattern with hardness or chemical composition different from that of a matrix on the surface of a position sensor axis so that it continuously varies in a direction of detection. CONSTITUTION:An alteration pattern C1 with hardness or chemical composition different from that of a matrix is placed on the surface of a position sensor axis 1 so that the pattern continuously varies in a detection direction X from high to low or from low to high. When the axis material is thus altered, electric and magnetic characteristics such as an electric resistance value and magnetic permeability are varied so that the characteristics of the position vary in a position detection direction from high to low or from low to high. Thus characteristics in each position can be detected permitting absolute positions to be known continuously.

Title: Pasting method for electronic part and formation method for ditching on adhesive tape
Inventor: NOGUCHI ISATO
IPC: C09J7/02
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To accurately, easily, and efficiently form, from one surface side of an adhesive tape, a ditch by engraving ditches which are orthogonal each other and are not cut through to the other surface side on the supplied adhesive tape using a ditching means. SOLUTION: Ditch pitches P1 and P2 are formed on an adhesive tape by moving a slider along a guide rail in Y direction by a moving amount P3 between chips 12a of an electronic part 12 while moving it along the guide rail in X direction. Thus, a cutting blade is moved in X-Y direction based on a pre-input data. When the cutting blade is moved in Y direction, a cutting-blade rotary mechanism provided in a cutter holder rotates the cutting blade by 90 deg., cutting the adhesive tape in Y direction as well. Thus, ditches 30a are formed for die (square) or strip (rectangular) in the specified region of the adhesive tape.
