Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To automatically recognize the hollows of a turning machining product and to decide a tool that is suitable to the hollow machining. SOLUTION: The finishing shape of a turning machining product is successively defined as segments AB, BC, CD... at a single end A of the finishing shape and traced for each of branch points B, C, D... at and after an intersection point A. If the machining product moves in its axial direction and also in the direction (minus direction of axis Z) opposite to the axial direction, the section set between both directions is decided as an end face hollow. If the machining product moves in the direction perpendicular to its axial line (axis X) and also in the direction opposite to the vertical direction, the section set between both directions is decided as the radial direction hollow. In such a way, the hollows are recognized for the turning NC data.

Abstract: PURPOSE:To reduce the number of setup units of an autotransformer, by installing each electric-car line and a common cable line in parallel, and connecting a communication trouble preventing autotransformer, serving as common use, to each electric car line and each rail, while setting up each switching device among them. CONSTITUTION:At the time of usual feeding, each of switches ST and SR is turned on, while each switch SFT comes off. Therefore, each feed circuit is formed in both up and down lines, and each induced current to be produced as an electric car travels on an up electric-car line 1b and a down electric-car line 1f is absorbed by each autotransformer AT. In consequence, inductive interference against a communication-information line is surely preventable.

Title: Detection of ink reside in ink jet printer
Inventor: ONOZATO TAKU
IPC: G01F23/00
Filed: 1991-07-29
Abstract: PURPOSE:To eliminate the possibilities of generating blank print and maintain high printing efficiency even when data is printed on a large-sized sheet by detecting a residual ink amount frequently in the equal speed motion area of a carriage. CONSTITUTION:A residual ink amount in an ink tank 10 is detected each time a carriage 8 moves in one direction and during the movement of the carriage 7 at an equal speed. A cloee area inside B and C which are residual ink amount detection positions, that is, a printing completion position can be determined by detecting said area with the counting of the number of printing pulses. If the carriage 7 arrives at this position, a bias current is run for a short time to the base of a transistor at that time, and in turn, an electric current is run to the ink of the ink tank 10 through a partial voltage resistor. Subsequently, an output from a comparator changes over depending on the residual ink amount of the ink tank 10. If the output changes over, a printer control circuit stops the operation of a printer temporarily.
