Title: Straight line approximation system for linear graphic input device
Inventor: KOIZUMI JUNICHI
IPC: G06T3/00
Filed: 1989-03-20
Abstract: PURPOSE:To approximate a line segment array, which links >= three specific points, to a single straight line by continuing a tracing processing and an approximation processing from a branch point to be the specific point by means of a selecting/ continuing means. CONSTITUTION:A tracing/approximating means 10 decides the propriety of approximation using the shifted distance between the straight line, which uses the arbitrary specific point to be the branch point or an open point in the point series of the linked line array as a trace starting point, and, when the approximation is attained, the series point in the point series array as a reference, the next series point is traced, and the propriety of the approximation is decided. When the advanced series point is the branch point, a first tracing/approximating means 11 selects the point series having the line segment, which forms a cosine angle closest to + or - pi together with the straight line, out of the connected line segments, and when the trace start point is the branch point, a second selecting/continuing means 12 selects the point series having the line segment, which forms the cosine angle closest to + or - pi, in the same way. Thus the line segment array linking >= the three specific points can be approximated to the single straight line.

Abstract: PURPOSE:To reduce a load torque of a correction wheel and a sliding pinion while enabling the securing of the strength of teeth of a gear part of the correction wheel by forming the teeth thereof in a taper so that the thickness thereof becomes less gradually toward the center of the sliding pinion. CONSTITUTION:In the normal state with a winding stem 1 forced in, a sliding pinion 15 is made free and when a pointer is operated by a driving with a motor, the sliding pinion turns idly even when the rotation of a minute wheel 20 is transmitted to a crown gear 16. At this point, as the thick of the teeth 21 of the minute wheel 20 is made less in a taper toward the center of the sliding pinion, the torque by the meshing with the gear 15 becomes so less that the pointer operation will not be disturbed by a load torque, Even when the rotation of the sliding pinion 15 is transmitted to the minute wheel 20 under the correction of time, the gear part 21 can secure the strength of the teeth thereof because of the tapered tooth part and withstands the action of the load torque sufficiently as caused by a second slip mechanism for stopping a second pointer.

Filed: 1988-03-25
Abstract: PURPOSE:To execute the back-up of receiving data and to attain high speed communication by providing a means to record and reproduce an analog signal, which is received or transmitted and received, as a sound band signal. CONSTITUTION:When paper exhaustion is generated in a printer 15, a paper exhausting flag is set and a printer output is omitted. Then, receiving data are wholly recorded to a tape recorder 13. When the communication is ended, the recording is stopped and line connection is disconnected through a network control unit NCU11. Then, processing is ended.
