Title: High speed search system in video disc reproducing device
Inventor: YAMANOUCHI TAKASHI
IPC: G11B27/10
Filed: 1983-04-22
Abstract: PURPOSE:To attain high speed search by obtaining a track pitch correcting amount before start of search, feding a head in high speed when an objective track is far, switching the mode to the continuous jump when the track is close to a value below a prescribed value and applying the continuous jump immediately when the objective track is near. CONSTITUTION:A rotating angle detecting signal generated by a photosensor 13 and a rotary angle detecting circuit 14 is given to a track pitch correcting device 16 and the track pitch correcting amount is calculated based on the address information relating to the track number from a control circuit 11 and the rotary angle detecting signal. In starting the search, this correcting is applied to the difference between the objective address and the present address and when the value after correction reaches a prescribed value (when a distance to the objective addresss is far), a pickup means is moved in high speed. In the process of the high speed feeding, the moving track number is subtracted based on the said rotary angle detecting signal and the amount of correction and when the result of subtraction is zero or negative, the high speed feeding is stopped and the continuous jump is started. That is, the difference with the address is detected at one TV-field and the track number is corrected and then the continuous jump is applied.

Title: Processing method for solid surface
IPC: H01L21/268
Filed: 1992-03-27
Abstract: PURPOSE:To solve the problem of the contamination of a vacuum vessel by etching atomic layer units on a solid surface through repeating a process for forming a stable compound layer of one to several-molecule layers of oxide, nitride, etc., on the solid surface and for removing the compound layer. CONSTITUTION:In an oxygen molecule, a vibrational state is mainly excited by heating so that the oxygen molecule has energy being higher than that of oxygen in a normal ground state. An oxidizing velocity increases by this energy so that an extremely thin oxide film can be formed stably. When the oxygen molecule 111 is OFF, a chopper 110b opens and HF is applied to a sample 103. This oxide film-removing method is high in selectivity so that only a layer oxidized in a previous cycle can be removed. When this process is repeated, e.g. the sample 103 is etched for each three-atom layer. The atomic layers to be etched in one cycle are adjusted in the size of the notch hole of a chopper 110a, rotational speed, sample temperature, furnace temperature, etc. Thus, it is possible to control the number of the atomic layers to be etched in one cycle.
