Title: Accuracy measuring device for gear engagement
Inventor: NAKAMURA SADAO
IPC: G01M13/02
Filed: 1979-12-14
Abstract: PURPOSE:To simplify both the structure of an accuracy measuring device and its operation, by counting the number ni of output pulses in the other side every time the when number of output pulses in one side reaches plural number N among the pulse generators connected to two units of gears. CONSTITUTION:The rotations of the gears 1 and 2 having the number of teeth Z1 and Z2 each are applied to the pulse generators 5 and 6, and the generators 5 and 6 produce the pulses in proportion to the rotational angles respectively. These output pulses are applied to the arithmetic circuit 8. Here the same device is used for both generators 5 and 6. In such constitution, the output count number ni of the generator 6 is taken into the register 83 every time when the output of the generator 5 is counted by plural number N. The number ni multiplied by the rotational angle means tne actual rotational angle of the gear 2, which is then converted logically into the rotational angle of the gear 1. Then the difference DELTAepsiloni is obtained to the actual rotational angle of the gear 1 from the equation 1, and the accuracy epsilonn of engagement is obtained from the equation 2 respectively. In this way, both the structure of the device and the operation can be simplified.

Filed: 1986-07-15
Abstract: PURPOSE:To moderate ionic concentration on the central part of a substrate to enable a thin film uniform in thickness and quality to be formed, by making mesh electrodes be disposed facing to electron-drawing electrodes and on the central side of an ionization part. CONSTITUTION:In an ionization part, mesh electrodes 30 having the same potential as ionization filaments 9 are disposed facing to electrondrawing electrodes 10 and on the central side of the ionization part against the electron-drawing electrodes 10.
