Title: Roll interval controller
Inventor: MATSUBARA MASAMI
IPC: B22D11/20
Filed: 1979-12-26
Abstract: PURPOSE:To improve the quality of products by setting a preferable roll reaction force range at a reference roll interval in terms of the quality of producs and then by adjusting the roll interval so that when the detected roll reaction force deviates beyond the set range, it will enter in the set range automatically. CONSTITUTION:When a reference set mode signal and the set value of reference roll interval are inputted from command device 11 to controller 2, set data X is read in circuit 14. When the data is faulty, a data fault signal is outputted to command device 11 and when normal, pulse generator 17 inputs a pulse signal to pulse driving unit circuits 15 and 16 or servo cylinder 10 at the same time and counter 18 counts number (y) of pulses. Consequently, upper frame 9 ascends when y<x and descends when y>x. On the other hand, comparing circuit 18 makes a comparison between (x) and (y) and, when y=x, send a pulse generation  stop signal to pulse generator 17 and a driving completion signal to command device 1. As a result, servo cylinder 10 stops and upper and lower rolls are kept at  the reference interval.

IPC: H01L21/3205
Filed: 1989-07-06
Abstract: PURPOSE:To efficiently execute an accurate inspection of a step coverage by means of a nondestructive inspection by a method wherein a holder on which a wafer to be inspected is loaded so as to face a light source of an inspection light in such a way that its angle with reference to an optical axis of the inspection light can be changed arbitrarily. CONSTITUTION:When one wafer is inspected, an angle of a wafer 1 to be inspected with reference to X-rays 7 as an inspection light is arranged so as to changed freely. That is to say, when the wafer 1 to be inspected is tilted in such a way that its right is raised, the X-rays 7 are transmitted through a discontinued part of a metal film in a right-faced stepped part 41 and can be detected with an X-ray vidicon 9 even when the X-rays 7 are incident from directly above. However, the X-rays cannot be transmitted at a left-faced stepped part 42. Then, when the same wafer 1 to be inspected is tilated in such a way that its left is raised, the left-faced stepped part 42 is faced toward an incident direction of the X-rays 7; as a result, the X-rays 7 are transmitted through the discontinued part of the metal film at the left-faced stepped part 42 which could not be transmitted; they can be detected with the X-ray vidicon 9. Thereby, problems that the inspection light cannot be transmitted and the like are not caused; an accurate inspection can be executed.
