Abstract: An operation guide system is disclosed which is able to inform an operator only of input operations presently available for a computer, a word processor or the like, and guides operation automatically in case of invalid operation. When an operator taps one of the keys arranged on a keyboard, a key signal is sent out to a key comparison section. The key comparison section determines whether the input key signal is from a key assigned to an available operation in a current operation state or not by referring to information in a key table storing unit. When it is determined that the key signal is not from a presently valid key, it is determined whether a condition for outputting the guide is satisfied or not with reference to a guide condition setting section. If the condition is satisfied, an instruction is given to an operation guide output section to output the operation guide. Further, if the condition is not satisfied, another key signal is awaited.

Abstract: Provided is a code input apparatus for a computer or a word processor, in which determination is made whether a data file or a document file attached with a file name is prevented from being erroneously erased or from being kept in a confidence, and in the case of the prevention of erroneous erasure, the file name is directly used as a code for the file, but in the case of the prevention of keeping the file in a confidence, a code datum received by manual input is attached to the file, so that a time-consuming and laborious procedure in which a code for keeping a file in a confidence is attached to a file required to merely prevent the same from being erroneously erased can be eliminated, so that it is possible to prevent the file from falling into such a condition that the file cannot be opened.

In the method amorphous magnetic alloy ribbon prepared by quenching a melt of raw material is annealed at an elevated temperature lower than a crystallization temperature of the alloy, in a magnetic field.
