Patent number: 5939656Abstract: A music sound correcting apparatus for correcting a music sound signal entered thereinto to selectively supply the corrected music sound signal to a speaker and a headphone, is provided with a jack into which a plug of the headphone is inserted, and a detector for detecting whether or not this plug of the headphone is inserted into the jack. When the detector detects that the plug is not inserted into the jack, a frequency of the entered music sound signal is changed so as to be properly reproduced by the speaker. On the other hand, when the detector detects that this plug is inserted into the jack, the entered music sound signal is corrected so as to be properly reproduced by the headphone in such a manner that a sound image produced based upon the entered music sound signal is localized to a predetermined position. As a result, preferable music sound can be reproduced even when the speaker is used and the headphone is employed irrespective of a small amount of hardware.Type: GrantFiled: November 18, 1998Date of Patent: August 17, 1999Assignee: Kabushiki Kaisha Kawai Gakki SeisakushoInventor: Masayuki Suda

Patent number: 5686207Abstract: A method of forming a mask for photolithography comprises forming a transparent conductive film on a transparent substrate. The substrate and an electrode having a sharp front end are immersed in an electrolytic solution. The sharp front end of the electrode and the transparent film are then positioned close to each other while controlling a distance therebetween. The substrate and the electrode are then scanned relative to each other in two-dimensions while maintaining the distance between the sharp front end of the electrode and the transparent film constant. Thereafter, an electrochemical reaction is processed on the substrate while a voltage is applied between the transparent film and the electrode to form a mask pattern on the substrate. During repair of the mask thus formed, the substrate and the electrode are immersed in the electrolytic solution.Type: GrantFiled: July 19, 1995Date of Patent: November 11, 1997Assignee: Seiko Instruments Inc.Inventors: Masayuki Suda, Akito Ando, Tatsuaki Ataka
