Patent JP-S5732367-A (JP)
Title: Ion plating apparatus
Inventor: KOGA KIKUO
IPC: C23C14/32
Filed: 1980-07-31
Abstract: PURPOSE:To obtain substrate heating time and ion bombardment time according to the kind of evaporated particles by a simple operation by applying AC power to the substrate and controlling the generation timing of negative power and positive power. CONSTITUTION:AC power is applied to a substrate 2 from an AC power source 9 through a timing circuit 10 and a chock 11 for stabilization. When positive power is applied, electrons generated by the ionization of particles evaporated from an evaporation source 3 by a high frequency electrode 8 bombard the substrate 2, so the substrate 2 is heated. Next, when negative power is applyied, the evaporated and ionized particles deposit on the substrate 2. At this time, the input timing of signals inputted in the gates of thyristors 10a, 10b of the timing circuit 10 is regulated to control the power to preferable heating time and ion bombardment time according to the kind of evaporated particles.

Abstract: PROBLEM TO BE SOLVED: To provide a moving stage device in which the height of a sample placement face is reduced to provide high vertical rigidity from the face to a base. SOLUTION: This device comprises a base 1 having a horizontal guide surface 1a, and when one of two axes which orthogonally intersect each other within the horizontal plane of the base 1 is used as X-axis while the other of the two axes is used as Y-axis, a Y-axis stage 2 is fixed on one side of the base 1 while an X-axis stage 3 is placed on the guide surface 1a of the base 1 and connected to the Y-axis stage 2 by a stage connecting member 4. A sample stage 6 is directly placed on the guide surface 1a of the base 1 and a sample 7 is placed thereon. The sample stage 6 is connected to the X-axis stage 3 by a sample stage connecting member 5.  The Y-axis stage 2 causes the X-axis stage 3, the sample stage connecting member 5, and the sample stage 6 to reciprocate in the direction of the Y-axis via the stage connecting member 4, and the X-axis stage 3 causes the sample stage 6 to reciprocate in the direction of the X-axis via the sample stage connecting member 5. Therefore, the sample stage 6 can be moved freely on the guide surface 1a of the base 1 and any desired position of the sample 7 placed on the sample stage 6 can be adjusted to a position directly below an observation head 10.

Filed: 1986-05-09
Abstract: PURPOSE:To enable a highly reliable fail-safe control by outputting an abnormality detection signal of a predetermined period in overlapping with an operation command signal, and cutting off the operation command signal of an operation element canon through detecting abnormality at the abnormality detection signal having become absent. CONSTITUTION:During an engine operation, a micro computer 8 outputs operation command signals a, b of an H level, putting 'on' the transistor Tr 17 in an abnormality detection circuit 11, and thus a condenser 16 is discharged. Also, signals c, d are respectively at an L level and H level, and a motor 5 is driven in one direction, and a throttle valve is operated in the direction of closing. Since a narrow abnormality detection signal e overlaps with the signal b at a predetermined period, the Tr 17 is left 'off' when the abnormality signal e ceases to overlap with the signal b. And then, the condenser 16 is charged, and the voltage at an F point surpasses a comparative voltage Vs, resulting in the abnormality detection signal e becoming H. Accordingly, signals c, d becomes respectively an L level and H level, and the throttle valve is operated in the direction of closing.
