摘要:
An input data check control portion, which compares input data with a decimal point check target word (step 64, 65) and, issues a warning when the input data is the decimal point check target word and the numerical value data of the input data is not given a decimal point (step 66), is provided. This structure enables the prevention of input mistakes of coordinate data and the like, which are easily made at the time of manual programming of a machining program for an NC machine tool, and also enables said input mistakes to be easily found.

An extrusion molding apparatus and an extrusion molding method is provided that permits deformation of molded body to be prevented and a sound extrusion molded body to be obtained even in the case where a soft extrusion molded body having low rigidity in a direction perpendicular to extrusion direction is molded. An extrusion molding apparatus 1 comprises a screw extruder 12 that kneads a molding raw material 80 and extrudes an extrusion molded body 8 from a molding die 11, and a conveying apparatus 3 that supports said extrusion molded body 8 extruded continuously from the screw extruder 12 and conveys same in the extrusion direction. The screw extruder 12 has an inclination angle θ between the extrusion axis A and horizontal axis H in the range of 15° to 85°. The conveying apparatus 3 is constructed so as to move a reception stage 32 that supports said extrusion molded body 8 extruded along said extrusion axis A on the outer circumferential surface thereof, generally in parallel to said extrusion axis A. The inclination angle θ is preferably in the range of 30° to 75°.

There is described a method for compensating tail end of rolling materials for rolling shaped steel sections in an optimum manner. According to this method, in a continuous tension free rolling operation of a shaped steel section comprising a flat section and a flange section through a plural number of roll stands, the operating speed of a first roll stand is reduced by a predetermined amount as compared with a second or succeeding roll stand when the crop at the tail end of the rolling material enters the first rolling unit, thereby to prevent overfeeding.

An apparatus for discriminating optical disks has an optical pickup provided with an objective lens having an effective numerical aperture of 0.55 to 0.65, which can compatibly reproduce information from a CD and an SD. The apparatus discriminates presence/absence of waveforms of two focus error signals detected when the effective numerical aperture of the objective lens is set at 0.55 to 0.65 and 0.20 to 0.45 respectively in a process of performing focus servo control, thereby discriminating various types of optical disks from each other. Thus, optical disks having different substrate thicknesses, different track pitches, different minimum pit lengths and different reflectivity can be quickly and simply discriminated from each other.
