Title: Magnetic recording medium
Inventor: HIBINO KUNIO
IPC: G11B5/65
Filed: 1983-05-12
Abstract: PURPOSE:To obtain a magnetic recording medium having improved durability, particularly, drivability in still state by providing a thin film of a ferromagnetic metal having the surface consisting partly or wholly of a metallic hydroxide on a nonmagnetic substrate, and coating the thin film with a layer of a fatty acid base lubricant. CONSTITUTION:After immersing a substrate 1 of such as polyester film or sheet for 1 day in pure water at 35 deg.C, a ferromagnetic metal such as Co alone or alloy of Co-Ni, etc. is deposited continuously by slant vapor deposition to form a thin film 2 of a ferromagnetic metal. Or, a thin film 2 of the ferromagnetic metal is formed by the continuous slant vapor deposition method using electron beam in the presence of 8X10<-5>Torr O2 on a dry substrate 1, then the film is allowed to stand for 24hr in an atmosphere at 60 deg.C and 90% RH. In this way, a part or whole of the magnetic thin film 2 is converted to a hydroxide of the metal. Further, a fatty acid base lubricant such as a higher fatty acid or a metallic salt thereof, or a higher fatty acid ester is coated on the thin film 2. The fatty acid base lubricant is bonded firmly to the OH group on the surface of the thin film 2 to form a layer of lubricant having superior durability. Thus, a magnetic medium having superior drivability and durability in the still state is obtd.

Filed: 1978-07-10
Abstract: PURPOSE: To secure a high-accuracy conversion into the desired frequency by setting the power voltage of the oscillation circuit independently from that of the output circuit and then controlling the power voltage of the oscillation circuit from outside.  
     CONSTITUTION: Variable power voltage V 1  is supplied to the oscillation circuit comprising inverter 101, the crystal oscillator and others; while power voltage V 2  is supplied to inverter 107 and program division/output circuit 109. The output signal of inverter 101 is supplied to circuit 9 via inverter 107, and thus the desired high-accuracy output frequency is obtained through output terminal 110 by setting the program input signal. However, the output frequency becomes at randowm since its setting is given in a digital way at circuit 9. Then a fine adjustment is given to the oscillation frequency by varying voltage V 1 , and the output frequency is set continuously through combination of the digital setting and the analog setting via the voltage. Furthermore, a miniaturization is possible for the device by storing the IC including the oscillator, the oscillation circuit, the output circuit and others into a single package.

Abstract: PURPOSE:To make circumferentially uniform the temperature distribution of a piping for leading a liquid that has overflowed from a prescribed level of liquid in a tank so as to prevent the piping from locally diformation, by providing means within the piping for stirring the liquid in the piping. CONSTITUTION:In an overflow system of an FBR atomic power piping, the liquid in a tank 2 is introduced via suction pipe 4 into the container 1 to be kept there to a certain level at all times.

Title: Analysis of charged particle energy
Inventor: KAWASE SUSUMU
IPC: H01J49/44
Filed: 1982-05-21
Abstract: PURPOSE:To enable energy-decomposing ability or energy-detecting sensitivity to be enhanced by enabling energy analysis to be performed efficiently by making the amplitude of perturbative a.c. voltage added to sweeping voltage, proportional to said sweeping voltage. CONSTITUTION:When primary electron rays 1 are irradiated upon a sample 2, electrons containing Auger electrons are discharged from the sample surface. The thus discharged electrons are deflected by applying a negative voltage to the outer cylindrical electrode 4 of an electron energy analyzer 3, and only electrons having a specific kinetic energy reach a detector 6. Although a usual- type spectrum is obtained by sweeping the utput voltage of a sweeping power source 8, a differential type spectrum is obtained by rectrifying sweeping voltage by using a combined transformer, adding perturbative a.c. voltage which is the output of an oscillator 9 to the sweeping voltage, and amplifying only components of electrons reaching the detector which have the frequency of perturbative alternating current. These spectra are recorded by an X-Y recorder or an X-Y oscilloscope.
