Title: Estimating apparatus for crevice corrosion of metal material
Inventor: INAGAKI KINYA
IPC: G01N17/02
Filed: 1993-10-06
Abstract: PURPOSE:To detect the generation time and the progress state of crevice corrosion by a method wherein an auxiliary electrode which is installed near a counter electrode is connected to a crevice-provided metal test piece via a resistanceless ampere meter. CONSTITUTION:An auxiliary electrode 14 which is installed near a counter electrode 4 is connected, via a definite liquid resistance R, to a crevice-provided metal test piece in which a metal test piece 10 and a crevice formation material 11 have been tightened by a Ti bolt-nut 12 or the like, and the potential of the crevice-provided metal test piece is controlled to the noble side by a natural immersion potential. Then, by using a no-resistance ampere meter 20 which is installed between an electrometer 15, which is connected to the test piece via the Luggin tube 19 for an electrometer, and the electrode 14 and the crevice-provided metal test piece, the change, with the passage of time, of a current which flows across the potential of the crevice-provided metal test piece and the electrode 14 and the crevice-provided metal test piece is measured. That is to say, when the potential is controlled to the noble side, a metal dissolution speed inside a gap is accelerated, and the generation and the progress of crevice corrosion are accelerated. In addition, the generation time of the crevice corrosion is found as a point of time in which a drop in the potential on the noble side of the gap part and an increase in the current are started, and the progress state of the crevice corrosion is evaluated on the basis of a current value after its generation.

Abstract: PURPOSE:To prevent a misalignment between a package substrate and its cap in a sealing operation and to prevent a glass protrusion due to the softening of a glass sealing material in a package for an airtight semiconductor device. CONSTITUTION:A low-melting-point glass 3 is applied to a sealing margin 8a on a cap 2 and a high-melting-point glass 4 is applied to a sealing margin 8b on a package 1 in such a way that they are respectively semicylindrically rounded.

IPC: G01B7/30
Filed: 1989-09-27
Abstract: PURPOSE:To enable detection of a position at a desired time without offset errors by exciting a primary side winding of a resolver by a pulse wave. CONSTITUTION:A pulse excitation signal generator 31 excites a primary side winding for uni-phase excitation of resolvers 20-30 by a pulse voltage Pex with a fixed width at a desired timing necessary for a position data based on a timing signal P2 from a timing controller 42.

Two kinds of pulse signals from the resolvers 20-22 are converted into numbers by a conversion start signal from the controller 42 with the converters 39 and 40 and outputted as sine signal Ds and cosine signal Ds to be inputted into a microcomputer 50. Thus, identification is made to clarity which resolver is involved by a timing signal t2.

Title: Initializing method for lens system
Inventor: SAKATA TOMOSHI
IPC: G03G15/04
Filed: 1988-10-07
Abstract: PURPOSE:To quit a serviceman call by moving a lens system according its position data stored in a nonvolatile memory and inverting the moving direction of the lens system unless a lens system reference position sensor detects the lens system by movement in a specific time. CONSTITUTION:The position data on the lens system is fetched from the nonvolatile memory 32 to decide whether the position is on the enlargement side or not, and the lens system is moved to the reduction side when on the enlargement side or to the enlargement side when on the reduction side. Then when the lens system begins to move, a timer is started, a lens driving motor 36 is reversly rotated unless the sensor 31 detects the lens system even after the timer counts up, and the timer is started again. In this case, when the sensor 31 detects the lens system before the timer counts up, the motor 36 is stopped and the initialization of the lens system is completed. Consequently, even if the position data stored in the nonvolatile memory 32 is different from the actual position of the lens system, the lens system is returned to its reference position and the serviceman cell is evaded.
