Title: Production of magnetic recording medium
Inventor: NIIMI HIDEAKI
IPC: G11B5/84
Filed: 1985-08-28
Abstract: PURPOSE:To substantially improve durability by providing a protective film layer on a magnetic layer by vapor deposition of an org. compd. contg. a straight chain hydrocarbon having a polar group as skeleton in a specific vacuum. CONSTITUTION:The protective film layer consisting of the org. compd. contg. the straight chain hydrocarbon having the polar group as skeleton is formed on the magnetic layer. The vacuum deposition is preferably executed in a vacuum kept under 1X10<-3>-1X10<-1> Torr. The average free stroke of the org. compd. contg. the straight chain hydrocarbon having the polar group is made short and the satisfactory vacuum deposition is not executed if the vacuum is lower than sand degree. The surface of the magnetic layer is contaminated by the oil flowing backward from a vacuum evacuation pump such as oil rotary pump or oil diffusion pump if the vacuum deposition is executed in the vacuum higher than said degree. The deposition of the org. compd. contg. the straight chain hydrocarbon having the polar group as skeleton on the magnetic layer with good adhesiveness is then not possible and the wear resistance is not substantially improved.

Abstract: PURPOSE:To eliminate the inclination of a ceramic board and the dispersion in the thickness of a semiconductor device by a method wherein a ceramic board provided with four legs of the equal length at the respective four corners is placed over a ceramic substrate whereon a semiconductor is installed. CONSTITUTION:A semiconductor pellet 3 is installed on one surface of a ceramic substrate 2 and is sealed off by a resin 5. A ceramic board 6 is placed on top of the resin 5. The ceramic board 6 is constituted of a rectangular portion 7 and legs 8 of the equal length extending in the same direction from the four corners of the rectangular portion 7. Due to the surface tension generated in the resin 5 in its gel stage prior to hardening, the substrate 2 positioned under the resin 5 and the board 6 over the resin 5 are attracted toward each other before they are fixed hard. The board 6 is now arranged parallel to the substrate 2 with a prescribed distance between them, which eliminates the inclination of the board 6 and the dispersion of thickness in the semiconductor device itself.

Abstract: PURPOSE:To approximate the output characteristic of a detector for a component having a large coefft. of absorption to linearity and to enhance the accuracy of measurement by providing the detector for the component having the large coefft. of absorption among the plural detectors corresponding to the plural components to the side face of a cell. CONSTITUTION:Both of the direct light which is emitted from a light source 20 and advances rectilinearly along an optical axis L and the reflected light enters the detectors 41, 43 provided on the optical axis L, but only the reflected light enters the detector 42 provided to the side face 10s of the cell 10; therefore, the quantity of the incident light on the detector 42 corresponding to the component having the large coefft. of absorption is sizably smaller than the quantity of the incident light on the other detectors 41, 43 and since the effective cell length of the detector 42 is shorter than the effective cell length of the other detectors 41, 43 the output of the detector 42 is not saturated to be broken of the linearily, unlike with the conventional analyzer, and the signal output characteristic itself approximates to the linearily; therefore, the signal correctly indicating the concn. of CO2 which is the component to be measured is outputted. As a result, the need for providing a costly linearizer on the output side of the detector 42 is eliminated and the constitution of this kind of the analyzer is simplified; in addition, the cost of the analyzer is reduced.
