Title: Generation of work contour
Inventor: UERUNERU GORUSUKII
IPC: G05B19/4069
Filed: 1985-02-02
Abstract: A process for generating a data structure of a computer model of a processed workpiece. The contours of the workpiece and the cross section of the tool, as well as the path movement of the tool, are analyzed in a grid such as is presented by a raster picture screen and associated image point memory of a microprocessor controlled graphic control unit of a numerically controlled machine tool. At each point of the coordinated grids the height of the workpiece is linked with the programmed processing depth of the tool and in this way the altered data structure of the workpiece is determined. The altered data structure can serve for the representation of the computer model thus determined on a picture screen. The linkage of the data from grid point to grid point is thus reduced to a number comparison for the Z coordinate, thereby maintaining both computer and apparatus capital expenses at a low level.

Inventor: NAKAI TADASHI
IPC: H03K17/687
Filed: 1981-02-10
Abstract: PURPOSE:To reduce influence by variance on the process, and to obtain a stable output characteristic, by inserting a resistance between a load driving buffer and an output terminal. CONSTITUTION:A resistance R1 is inserted between a connecting point of the drains of a P channel transistor T1 and an N channel transistor T2, and an output terminal 1. When a current flowing in the transistor T1 is denoted as I2 in a state that the transistor T1 is conducting, a potential difference against the ground potential VDD of the output terminal 1 becomes VDS+R1.I2 (in the expression, VDS denotes a potential difference between the source and the drain in a state that the transistor T1 is conducting). Therefore, when the transistor T1 is designed so as to satisfy VDS<<R1.I2, I2 is nearly decided by R1 and an outer load connected to the output terminal 1. This condition is realized easily by a shape of the transistor T1.
