Title: Film thickness measurement of non-electrolytically plated layer
Inventor: ITO KATSUTO
IPC: C23C18/31
Filed: 1986-03-06
Abstract: PURPOSE:To measure film thickness of an electrolytically plated layer continuously and easily with high accuracy, by converting into the film thickness a change of a value of electric resistance of a conductive member established in the same non-electrolitic plating environment as an electrolytically-plated part. CONSTITUTION:A metallic wire W is pinched at a top portion to a clamp 7 made of teflon, etc. located in a bucket frame 6 through an insulating sheath 8 such as a vinyl tube. A metallic-wire monitor is put in the same environment as a substrate during the course of the non-electrolytic plating and undergoes the same treatment process as the substrate. After immersion of a bucket 1 in electrolytic-plating solution, a clip 11 is placed between both ends of the metallic wire and thus, a change in the value of electric resistance of the metallic wire occompanying depositing of plated material thereafter can be identified continuously.

Title: Stepping motor
Inventor: AOSHIMA TSUTOMU
IPC: H02P8/38
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To accurately detect the step-out even when the step-out has occurred at any position of a rotor by detecting the information of the rotary board, wherein the rotation is performed in relation to the rotor, the board is divided equally in the circumference direction and a plurality of signal patterns, in which binary signals are recorded at the respective duty ratio, are sequentially arranged. SOLUTION: A male-screw shaft 4 is rotated by the drive of a stepping motor 3, and a lens holder 1 is moved in the parallel direction with the optical axis in correspondence. The moving amount is determined by the number of the drive pulses of the stepping motor 3. The problem occurs, however, when the load is increased by some reasons and the stepping motor 3 is driven under the state, wherein the step-out has occurred. Therefore, the presence or absence of the step-out is detected by a slit plate 5 of the rotary board and a photointerrupter 6 of a detecting means. Therefore, the step-out of the rotor can be securely detected with the simple constitution.
