Title: Correction of erroneous recording
Inventor: KUWABARA NOBUYUKI
IPC: B41J2/36
Filed: 1986-12-25
Abstract: PURPOSE:To enable a recorded image to be lifted off from a recording medium, by reducing the quantity of energy supplied to a thermal head by a predetermined quantity when a correction medium laid upon a recorded image is adhered to the image by heating the thermal head. CONSTITUTION:A correction medium 4 comprises a base 4a laminated with a thermal adhesive layer 4b. Generation of heat by a thermal head 6 is conducted by energizing heat generating elements 6b in the same pattern as that of a recorded image 6 while reducing the quantity of energy as a predetermined quantity of energy is supplied to the elements 6b. For example, when the recorded image 2 is corrected by a serialtype thermal head 6, the quantity of energy supplied for the first line l1 is taken as a reference value, and the quantities of energy supplied to the elements 6b for lines l2-l24 are sequentially reduced from the reference value. As a result, heat accumulation in a heat substrate 6a or a glaze layer is corrected, and an adhesive layer 4b caused to display uniform adhesiveness adheres to the recorded image 2. The recorded image 2 is lifted off when the correction medium 4 is separated from a recording paper 1, whereby correction is securely performed.

Title: Numerical control system
Inventor: SHIMA ATSUSHI
IPC: G05B19/4155
Filed: 1986-12-25
Abstract: PURPOSE:To increase the processing speed of a numerical controller in a high- speed working part by constituting the high-speed working part of an execution data format and outputting data of a read block if this block is constituted in accordance with the execution data format. CONSTITUTION:A program consisting of blocks constituted in an NC program language generated on the outside and blocks constituted in accordance with the execution data format is inputted to a numerical controller 2. When the block of a high-speed working command code is read in, the numerical controller 2 outputs read data to a servo system as it is in the case of a move command to perform pulse distribution because blocks following this block are already converted to binary data of the execution data format. In the case of an auxiliary function command, this command is outputted to a machine, a programmable machine controller, or the like. Thus, it is unnecessary for the numerical controller 2 to perform the decoding processing, the preprocessing, etc., of blocks stored in the execution data format, and therefore, the working speed is increased to perform the work at high speed.

CONSTITUTION:By the thermal oxidation of a silicon substrate 1, a silicon oxide film 2 is formed, and thereafter, a silicon nitride film is formed on the film 2. By the etching of this silicon nitride film, a new silicon nitride film 3 is formed, and thereafter, by the thermal oxidation of the silicon oxide film 2, a first oxide film 4 is formed out of a part of the film 2. Hereupon, in case of the forming of the first oxide film 4, a local stress is generated in a silicon crystal present below the end part of the first oxide film 4. By the further heat treatment of the same, this stress is further increased. By this stress, the diffusions of oxidation seeds are suppressed, and thereby, the oxidizing rate of the same is changed. Therefore, in case of the performing of this thermal oxidation, a part 6 made into a thin film and a protruding part 7 of silicon are formed respectively in the end part of the first oxide film 4. Still, after the forming of the first oxide film 4, a second oxide film 5 is formed by a thermal oxidation. In this way, both a gate oxide film which has along the shape of the first oxide film 4 and the protruding part 7 of silicon are utilized, and thereby, a quantum wire structure can be formed.
