    摘要: A basic spiral operation of a tool is controlled by storing, in a controller, an automatic operation program of a threading cycle which regulates the basic spiral operation of the tool corresponding to a thread shape by specifying a spindle revolving speed RC, a thread lead ZR and a thread cutting finish point Z2 or the like. A depth of cut by the tool is determined by an operator who operates a handle of a manual pulse generator to cut the work and confirms the cutting conditions.

    摘要: A machining limit area specifying method and a manual feed machining method using a numerical control unit capable of easily performing machining in a desired shape by manual feed. In specifying a machining limit area on an X-Y plane, a desired machining shape is defined by shaping data or a combination of some shaping data on the X-Y plane at a predetermined Z-coordinate, and the desired machining shape defined by the shaping data is specified as a machining limit area in which movement of a tool is permitted on the X-Y plane in manual machining using the numerical control unit. In specifying a machining limit area in the Z-axis direction, an inverse function using an X- or Y-coordinate value as a parameter is obtained based on a function for specifying the machining limit area on the X-Y plane on condition that a Z-coordinate value is used as a parameter, and the machining limit area in the Z-axis direction is specified based on the inverse function.

    摘要: A semiconductor photoelectric conversion device comprises a first non-single crystal semiconductor layer of a first conductivity type. A second non-single crystal semiconductor layer of substantially an intrinsic conductivity type is formed on the first semiconductor layer; the second layer comprises a first crystallized region and a second crystallized region. The second crystallized region has a similar crystalline structure as that of the first semiconductor layer and extends from the first semiconductor layer toward the first crystallized region where the degree of crystallization of the first crystallized region is less than that of the second crystallized region. A third non-single crystal semiconductor layer of a second semiconductor type opposite to said first conductivity type is formed on the intrinsic layer.
