Title: Machine translation system
Inventor: NAKAZATO SHIGEMI
IPC: G06F17/28
Filed: 1986-10-31
Abstract: PURPOSE:To simplify the editorial operation of an operator by presenting plural interpretations concerning only character string specified by the operator to the operator and translating a sentence with the interpretation selected by the operator. CONSTITUTION:In case of editing a translated sentence displayed on a display part 8, if an input part 1 indicates other interpretations concerning a certain character string of an original, an other interpretation control part receives the indication and retrieves interpretation information stored in a parsing syntactic analysis part so as to extract all the interpretation information concerning the specified character string and display it on the display part 8. And the input part 1 selects a piece of information and the other interpretation control part transmits the selected interpretation information to a construction conversion part. The construction conversion part examines cases according to the interpretation information and converts the case into the case of an object language. And a translated sentence generation part generates the translated sentence based on the case information of the objective language. Thus the operator can easily obtain the translated sentence with other interpretation.

Activation energy rays are irradiated onto the positive type light-sensitive resist film through a photo mask screening the part for forming a conductor from the activation energy rays. Then, as a discrimination treatment of an exposed and non-exposed parts on development, the resist film is dipped into a weak-alkali solution and then is dried. The resist film is developed, the exposed copper plating part is removed by etching, and the resist film on the remaining part for forming conductors is eliminated. An approximately 1-3% aqueous solution consisting of sodium carbonate, metasilicic acid soda, amine, etc., is desirable for the weak alkali aqueous solution. It is desirable that the temperature of a dipping liquid should be 20-35 deg.C and the dipping time should be 10-30 seconds.
