Title: Rust preventing method
Inventor: INOUE YOKO
IPC: C23F11/00
Filed: 1993-03-19
Abstract: PURPOSE:To prevent the generation of rust due to oxidation in a period between surface preparation for coating a metallic structural material and coating by treating the surface of the metallic product with an ascorbic acid solution. CONSTITUTION:The surface of the metal of the various metallic structural materials such as a tank for storing is coated with the ascorbic acid solution. The concn. of the ascorbic acid solution is preferably 0.1-0.5 weight/volume%.

Abstract: PURPOSE:To provide a polyurethane paint which has excellent transparency and fillability and fixability to wooden vessels, gives a coating film having excellent long-term stability, elasticity, etc. and is suitable for use in woodworking, by mixing a polyol contg. starch with a polyisocyanate. CONSTITUTION:A mixture of a polyol and starch is mixed with a polyisocyanate to obtain the desired polyurethane paint for woodworking. The amount of starch in the mixture of the polyol and starch is 5-60wt% and the particle size of starch is 2-100mum. Since the resulting polyurethane paint for woodworking contains an appropriate amount of starch having an appropriate particle size in the mixture of the polyol and starch, the filling of the paint into wooden vessels can be smoothly carried out and there is no possibility that wood part is readily exposed by polishing. Further, since the refractive index of starch particle is nearly the same as that of the vehicle, lowering in transparency is not caused by priming, etc.

Abstract: PURPOSE:To avoid a signal from a time delay element from inputting to a PID operation section, when an input signal is in failure, by providing the time delay element and a succeeding signal interrupting means at the post stage of an input processing section. CONSTITUTION:If an input signal from a transmitter 1 is in failure, a signal from an input processing section 3 is inputted to a time delay element 8, and an interruption processong element 9 is operated while the signal stays in the element 8 so that the signal can not input to a PID operation section 4, allowing to stop the operation of the operation section 4 with the failed input signal. Thus, an output signal 6 as the result of operation before the generation of a failure can be held so that the signal can be outputted from an output processing section 5 to avoid greater external disturbance to the process. On the other hand, the operator can know the failure through the display at a display section  10 due to a failure deciding output from the input processing section 3, and the  holding output signal 6 can be operated manually with an automatic-manual switching mechanism of the output processing section 5.
