Title: Stc signal generation circuit
Inventor: TANAKA TETSUZOU
IPC: G01S7/34
Filed: 1982-04-16
Abstract: PURPOSE:To enable a smooth switching with an automatic correction of a gap at a switching point by determining the difference in the sensitivity time control (STC) voltage after and before the switching when a switching signal is generated corresponding to a specified distance and bearing in a radar receiver to be added to or subtracted from other STC control voltages after the switching thereof. CONSTITUTION:A differential voltage is determined with an adder 19 between two STC control voltages outputted from adders 16 and 17 and fed to a gate circuit G20. When a switching signal is generated at the distance r1, the differential voltage is fed to an adder 21 with the output of the adder 16 and subtracted therefrom and results are outputted from a selection circuit 18 so that the R<4> characteristic will be switched over to the R<2> characteristic smoothly at the distance r1 and the R<2> characteristic is set in the range of distances r1-r2. A differential voltage is determined with an adder 22 between outputs of adders 17 and 21 and fed to a gate circuit G23. When a switching signal is generated at the distance r2, the differential voltage is fed to an adder 24 with output of the adder 17 and outputted from the selection circuit 18 so that the R<2> characteristic will be switched over to the R<4> characteristic without gap at the distance r2 and the R<4> characteristic is set in the range of distances r2-R.

Title: Magnetic recording medium and its production
IPC: G11B5/84
Filed: 1992-03-19
Abstract: PURPOSE:To enhance the wear and corrosion resistance of a magnetic recording medium by improving the hydrophobic property of a protective film formed on the magnetic film of the magnetic recording medium. CONSTITUTION:Fluorine atoms are bonded to the surface of a protective film 3 of carbon, etc., formed on a magnetic film 2 by fluorination to form a fluorinated layer 4. Since the surface of the protective film 3 is stabilized and the hydrophobic property is improved, the sliding characteristics (wear resistance) and corrosion resistance of the resulting magnetic recording medium are enhanced. The fluorination is carried out by forming activated parts (high energy state) on the surface of the protective film 3 by dry etching such as plasma treatment or ion etching, adsorbing gas contg. fluorine atoms on the parts and tightly bonding fluorine atoms to the parts.
