Title: Anticorrosive coating method
Inventor: FUKUSHIMA TATSUO
IPC: B05D7/14
Filed: 1984-02-24
Abstract: PURPOSE:To prevent the softening and dissolution of the coated film of inorganic zinc dust by coating a paint, contg. a high condensate not having a silanol group at the end of the molecule as a vehicle, on the coated film of zinc dust. CONSTITUTION:A paint contg. zinc dust as an anticorrosive pigment is painted on the material to be coated by using mater-soluble alkali silicate or alkyl silicate as a vehicle. A high condensate not having a silanol group at the end of the molecule is obtained by hydrolyzing a mixture of organic silicon compds. shown by formula I (where, R is a hydrocarbonic group having 1-8C) and formula II (where, R' is a hydrocarbonic group having 1-12C, and R is the same as before) and/or its low condensate, and regulating the pH to >=7. And a paint contg. high condensate as a vehicle is painted on anticorrosive coating. An anticorrosive coating having excellent resistance to water, inert gas, and solvents can be obtained in this way.

Title: Image pickup device
Inventor: YAMADA KUNIHIKO
IPC: H04N5/232
Filed: 1992-02-21
Abstract: PURPOSE:To provide an image pickup device which can obtain a zooming in- focus state in a simple mechanism. CONSTITUTION:The diaphragm 23 of an image pickup optical system has a substantially symmetrical shape with addition of an ND filter 24. Thus, the luminous flux becomes symmetrical on an image pickup surface 2-1 in an out- focus state as shown in the diagram. Under such conditions, the video signal equivalent to an edge of an object is transmitted through a logarithmic amplifier. Thus, the waveforms A5 and B5 are produced in response to the back and front focus states, respectively. As a result, a back focus, front focus, or in-focus state can be judged without vibrating a lens system or an image pickup element in the direction of an optical axis.
