Title: Gap measuring adhesive paper
Inventor: SUZUKI HIROFUSA
IPC: G01B5/14
Filed: 1988-12-16
Abstract: PURPOSE:To make it possible to judge the value of a gap simply by sticking papers having the different thicknesses in a staircase pattern, coating the uppermost part of each thickness with a soft metal at a uniform thickness, and checking the thickness of the paper which is damaged and discolored by compression. CONSTITUTION:On a sheet of adhesive paper 4 having a thickness of 0.05mm, base papers 3 each having a 0.05-mm thickness are arranged increasingly in a staircase pattern. A metal film coating 2 whose main component is a soft metal and thickness is 0.05mm is stuck on the surfaces of said papers. Numerical values 1 showing the total thicknesses are printed at the centers of the coatings 2. To measure a gap C between a rotary body 5 and a projection 6 of a stationary part, gap measuring adhesive papers 7 are stuck to the outer surface of the rotary body 5, and the rotary body 5 is slowly rotated. The adhesive papers having the thicknesses less than the gap C pass the part beneath the projection 6. When the paper 7 having the thickness larger than the gap C comes, the coating 2 is damaged. The part between the maximum thickness and the thickness having the damage is judged to be the value of the gap.

Title: Deflection yoke
Inventor: OKUYAMA NORITAKA
IPC: H01J29/00
Filed: 1988-12-19
Abstract: PURPOSE:To reduce unnecessary radiation both in front of and in the rear of a deflecting yoke simultaneously by installing two sets of auxiliary coils that cause horizontal deflection current to flow, in such a manner that they are separated from each other along the tube axis and are located symmetrically with respect to the center axis in horizontal deflection direction outside the deflecting yoke. CONSTITUTION:The compensating magnetic field produced by a first auxiliary coil 6a acts in a direction opposite to the unnecessary radiation field caused by a high frequency horizontal deflection field both in front of and in the rear of a deflecting yoke 1. As a result, the unnecessary radiation field is nearly offset in front of the deflecting yoke 1, while an unnecessary radiation field of inverse polarity is produced by excessive compensation in the rear. At the same time, the compensating magnetic field produced by a second auxiliary coil 6b hardly acts in front of the deflecting yoke 1 but acts in the same direction as the unnecessary radiation field caused by a horizontal deflection field in the rear of the deflecting yoke 1. Thus, the unnecessary radiation field of inverse polarity remaining in the rear of the deflecting yoke despite compensation by the first auxiliary coil 6a can be compensated for by the second auxiliary coil 6b. This results in the cancellation of the unnecessary radiation fields both in front of and in the rear of the deflecting yoke 1.
