Title: Cr system composite plating steel plate excellent in corrosion resistance after work
Inventor: ANDO SATOSHI
IPC: C25D5/26
Filed: 1993-02-05
Abstract: PURPOSE:To obtain the Cr system composite plating steel plate excellent in corrosion resistance after work by decreasing the Cr content of the plating film of the first layer and controlling a film thickness in a specified value in the Cr system composite plating. CONSTITUTION:The plating layer on the steel plate is a two layer constitution, the first layer is the Zn-Cr composite plating layer which has 2-10mum film thickness and contains 0.1-5wt.% Cr. The second layer is the Zr-Cr composite plating layer which has 0.01-2mum film thickness and contains 5-60wt.% Cr. By compositing the Cr in a suitable ratio in the first layer like this, the sacrificial corrosion preventive period of Zn is turned into durable state. By incorporating at least one kind of ferrous group metal among Fe, Ni and Co beside Zn and Cr in the plating film of the first layer, the corrosion resistance and the weldability of the first layer is improved. Because the second plating film layer rich in Cr content is readily stripped off when the layer is too thick, <=2mum thickness is preferable.

IPC: G01L13/06
Filed: 1995-03-01
Abstract: PURPOSE: To provide a highly reliable pressure sensor having a highly accurate detecting characteristic regardless of a temperature cycle and high static pressure. CONSTITUTION: Since the outside diameter of a post 12a is smaller than the external shape of a silicon stand 10 and is larger than the diameter of a through hole 100 in a central part, the joining area of the post 12a and the silicon stand 10 is small. In order to avoid contact between a central rigid body part 2 and the silicon stand 10, a notch part 10a is formed on the silicon stand 10. The notch part 10a is almost a circular shape, and the diameter of this notch part 10a is set larger than the diameter of the central rigid body part 2. The through hole 100 having a diameter smaller than the diameter of the notch part 10a is formed in succession to this notch part 10a. Since the jointing area is small, heat strain in a joining process can be reduced, and a difference in offset voltage of a pressure sensor by heat strain and modulation of a span can be restained, and an output temperature characteristic of the pressure sensor can be improved.
