Abstract: PURPOSE:To absorb a difference in tape speed during recording among respective VTRs by detecting a DC component applied to a head actuator, deciding on the direction of deviation in speed reference on the basis of the DC component detection result, and correcting the speed reference finely. CONSTITUTION:The speed reference value from a speed command setter 2 is passed through an addition point 1 and compared 3 with the speed signal from a speed detector 9 and the obtained speed error signal is converted by a gain corrector 4 so that the gain is invariably constant. A tracking error signal is added to this signal by an adder 5, whose output is passed through a compensating filter 6 and a driving circuit 7 to drive a capstan 8. The rotation of a motor 8 is converted 10 into a tape traveling phase, whose relative difference from the head displacement by a head actuator servo device 13 is obtained from an adder 11. This difference is supplied to a tracking error detector 12 and tracking control is performed by the motor 8. Further, the DC component from a device 13 is detected 14 and a same speed reference value is corrected finely 16 on the basis of the decision result as well as in recording and applied to the addition point 1.

Title: Manufacture of compound semiconductor device
Inventor: KAMAGUCHI TOMOKO
IPC: C23F1/12
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To remove sulfur adhering to the surface of a gate electrode after the gate electrode is formed by drying etching with SF6 gas. SOLUTION: A WSi film is deposited on a compound semiconductor substrate 1. Then a gate electrode 6a is formed by over-etching the WSi film with CF4 gas after the film is etched through a resist mask 7 with a reaction gas of SF6 . Since the sulfur which adheres to the surface of the electrode 6a during the etching with the SF6 gas is removed by the over-etching with the CF4 gas before the next heat-treating process, the thermal diffusion of the sulfur to the n-type layer of the substrate 1 is prevented and the Schottky barrier height can be stabilized at a high level. In addition, the threshold voltage of a compound semiconductor device can be stabilized and the yield of the device can be improved.
