Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To lessen the warp of a substrate by providing a processing distortion layer on the main face on the side of a support substrate out of both main faces. SOLUTION: A separation groove is made on the surface of a semiconductor substrate 10 to become a semiconductor single crystal region 11, and next, an insulating film 12 is made on the surface of the semiconductor substrate 10.

IPC: G10H1/22
Filed: 1987-12-02
Abstract: PURPOSE:To prevent the sound generation of other keys from being stopped by providing a continuous key depression detecting means, a detecting means, and a comparing and selecting means. CONSTITUTION:This electronic instrument is equipped with the continuous key depression detecting means 1 which detects whether or not the musical sound of the same key as a newly depressed key being already assigned to a musical sound generation channel and the detecting means 2 which detects the 1st quantity of sound generation of a musical sound to be generated by new key depression and the 2nd quantity of sound generation of a musical sound corresponding to the point of time when a sound is generated by new key depression with the same key which is already assigned to the musical sound generation channel. Then the comparing and selecting means 3 compares those 1st and 2nd quantities of sound generation with each other and selects the side of a large quantity of sound generation when continuous key depression is detected by the continuous key depression detecting means 1 to generate a sound preferentially. Consequently, the quantity of sound generation never increases unnecessarily at the time of continuous key depression and the musical sound generation channel is not occupied too much, so the stop of the sound generation of other keys can be evaded.

Filed: 1989-11-22
Abstract: PURPOSE:To obtain a stable analyzed result by executing the shape analysis of a picture based on a rough shape such as the distinguishment of a straight line and a curve or the direction of the curve. CONSTITUTION:By using a curvature code generation part 3, curvature code storing memory 7 and curvature code table 8 to show a relation between a picture element near an attention picture element and a curvature code, the curvature code is calculated to know which direction and how much angle a picture element train changes the direction and this curvature code is smoothed at every several picture elements. Therefore, the influence of the change in the local shape is suppressed at a minimum and while paying attention to the change of the rough shape, the picture element train is divided into a part, where a straight line is formed, as a linear part, a part, where the curve to turn to right is formed, as a right turn curve part and a part, where the curve to turn to left is formed, as a left turn curve part. Accordingly, it can be known which stroke components the picture is composed of. Thus, the rough shape feature is extracted and the stable analyzed result can be obtained.
