IPC: C25D5/48
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance of a metal plated steel sheet or a noniron metallic material used for domestic electric appliance or building materials. SOLUTION: A blast furnace slag powder or a convertor slag powder of a by-product in the production of iron and steel is controlled to be <=1μm in the particle diameter. An organic resin coating film such as an epoxy resin or an acrylic resin containing the slag controlled in the particle diameter is applied on the steel sheet with <=5μm film thickness. As a result, since chromium is not contained, the fear of the environmental pollution in chromating is eliminated. Keeping corrosion environment alkaline, the slag powder contained in the organic coating film acts to prevent the corrosion of zinc or tin of metals for plating.

Abstract: PURPOSE: To improve reliability of an MLS by constituting it by way of providing a plural number of beam control parts and a monitor to select the beam control parts in a normally working state. CONSTITUTION: An RF electric power signal from a transmitter 14 in a normal state selected by a switching apparatus 15 is distributed at a specified electric power ratio by a distributor 16 and each of the distributed signals is inputted to a phase converter 12. In the meantime, phase data from beam control parts 13, 30 are respectively accumulated and added by an adder and a latch of monitors 33, 34 respectively. When timing signals of the control parts 13, 30 are inputted to a comparator, two of the phase data stored in an ROM are compared with each other and they are outputted to a logical circuit 35. The logical circuit 35 selects either one of the input phase data of the control parts 13, 30, and a beam is formed in the specified direction from an input switching apparatus 32-the phase converter 12 a radiant element 11.  In this way, the control parts 13, 30 are monitored by a monitor 31, and as they are switched over to each other whenever either one of them fails and their phase data can be acquired, it is possible to improve reliability of a system without stopping the system.

Abstract: PURPOSE:To make it possible to detect an abnormal temperature, by forming shape memory alloy into such a shape that the valve closing force of a valve closing spring for a valve element for opening and closing a compressed air valve hole disappears when a predetermined temperature is attained. CONSTITUTION:A valve closing spring 13 for a valve element 10 for opening and closing a valve hole 13 surrounds around the outside of the small diameter section of a valve rod 26, abutting at one end against a spring retainer 27 on a valve rod 26 and at the other end against a spring retainer 14. The valve closing spring is set so that it is deformed to extinguish its spring action when a predetermined low temperature is attained. The spring action of the valve closing spring 13 disappears due to leakage of LNG so that the valve is opened, and therefore, compressed air is fed. Accordingly, an abnormal temperature is surely detected, thereby it is possible to expect safe operation.
