Title: Method for deciding overload of tool for machining along ridge line, and method for machining along tool overload prevention ridge line by using the method
Inventor: KURODA YOSHINORI
IPC: B23Q15/00
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To properly evaluate a tool load by a CAM system. SOLUTION: At a process 1, data of a three-dimensional mold shape mode, data on a tool route along a ridge line, data, such as the outside diameter of a tool, and data on a machining condition, such as quality of a material, containing machining allowance, and a tool feed speed, are inputted. The tool in a three-dimensional shape and a mold shape are brought into a two dimensional model on a reference plane passing through the position of each constituting point of the tool route, crossing an X-Y plane at right angles, and also crossing a tool route, projected on an X-Y plane, at right angles. At a process 2, a cutting area at the periphery of a tool is roughly calculated by using a tool and a two-dimensional model in the shape of a mold. From the roughly calculated cutting area and the input data, it is decided whether or not the tool is brought into an overload.  At a process 3, information on a deciding result is added to data of each constitution point where a reference plane to effect decision of the tool route is positioned, and data on a tool route with overload information is outputted.

When the molding machine is closed, the porous elastic member 7 is brought into tight contact with an outer surface of a plastic member 2 which is to be fitted in a molding surface protrudingly formed in a lower mold 4, and depressed to shrink. A degreasing solution is supplied to the porous elastic member 7 through a hose 9 connected to a supply opening 8 and passing through the upper mold 3. The degreasing solution runs from a supplying means 12 placed on a supporting member 11 protrudingly secured to a column 10 of a press 1, to the supply opening 8. When the porous elastic member 7 is brought into tight contact with the plastic member 2, the porous elastic member 7 shrinks, and the degreasing solution soaks, out. Consequently, the oil is melted away from the plastic member 2 which is in turn heat- exchanged by the cold degreasing solution and accelerated in curing.

The final product, 7-ACA, is then prepared by cleavage of the adipoyl side chain using an adipoyl acylase. The entire synthesis, accordingly, is carried out using bioprocesses, and is efficient and economical.

Abstract: PROBLEM TO BE SOLVED: To prevent the resolution of luminance gradation from decreasing with respect to a dark video signal. SOLUTION: An interface device 9 prevents the resolution of luminance gradation from decreasing by setting a dynamic range Vref of an A/D converting circuit according to peak value of an analog video signal Vin. Further, an interface device 9 sets a luminance control signal BCONT for deciding a luminance value of the video signal to be displayed according to the peak value of the analog video signal. As the result, the interface device can generate a display signal, even if it is a dark video of which analog video signal level is relatively low, has luminance (brightness) according to the darkness and displays the video having sufficient resolution of gradation. Moreover, it is also possible to display a video having similar optimal resolution of gradation by converting a supplied digital display signal into a converted digital display signal according to a maximum gradation level.
