Title: Thick line drawing system for dda circuit
Inventor: KATO MASANORI
IPC: G06T11/20
Filed: 1987-12-22
Abstract: PURPOSE:To form a thick line as a result by drawing a line segment in a more vertical width direction at every point in a length direction with the aid of a DDA when the respective points in the length direction based on the DDA (digital differential analyzer) algorithm of Bresenham. CONSTITUTION:At first, an error term for a length direction (lerr) and an error term for a width direction (werr) are prepared. The path of (b) in a figure is decided according to the code of the (lerr) and the path of (a) or (a') is decided according to the code of the (werr). Since the length direction is intersecting orthogonally with the width direction, the initial value of the error term, an increment when the error term is negative and an increment when the error term is positive are equally expressed by formula I for both of the error terms. Then, when the sequence of points are formed in the width direction and in an inverse order for satisfying a condition that the point is not pinned by an identical coordinate point, the identical path is needed to be traced inversely to the case of a correct order. For example, the path 11 in the figure is decided, the update of the error term there is expressed by formula II.

IPC: B29C45/76
Filed: 1987-12-25
Abstract: PURPOSE:To enable the abnormality in the check-valve of a screw tip portion and a screw to be detected automatically by providing a means for detecting it as an abnormality when the rotating torque exerting a screw during the injection and the keeping pressure becomes over the predetermined tolerance. CONSTITUTION:When abrasion or damage produces in the check-valve 1, the molten rein compressed by the screw 2 during the injection and keeping pressure flows backwards along the spiral groove formed by a cylinder 3 and the screw 2, so that the rotating torque opposite to the one in its metering time produces in the screw 2. Inasmuch as this rotating torque is transmitted to a motor shaft 7 and a rotating displacement produces in a servo-motor 8, a pulse corder 9 detects the rotating displacement and the error rate of the present position to the servo-motor stopping position is stored in the error resister of a servo- circuit 10. As the error rate becomes above the limitation of the tolerance (epsilon), CPU 19 for PMC outputs an alarm via BAC 18 and performs an abnormality indication by means of CRT/MDI or the like, furthermore, discontinues the driving force of the servo-motor for an injection shaft.

Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To improve the operability by automatically displaying menu items by slight operation for only fixing an input pen on a screen for a certain time. SOLUTION: An elapsed time measurement processing part 13 measures the time elapsed after a pen tip part is brought into contact with a display screen, i.e., the time when the pen tip part is continuously in contact with the display screen. Then a pen movement recognition processing part 18 decides whether or not the coordinates measured by a pen coordinate measurement processing part 13 changes according to the time measured by the elapsed time measurement processing part 13. Then a menu call processing part 14 calls prepared menu items onto the display screen when judging that the pen is fixed on the display screen for the specific time.  For example, when the pen movement recognition processing part 18 judges that the coordinates of the pen tip part is fixed to the same coordinates for the specific time, the starting items of the menu are called onto the display screen and displayed.
