摘要:
If a plurality of wafers are placed on each shelf of a rack in a pod, some problems will arise in processing processes. In addition, in some apparatus for detecting wafers, driving means having a not so high stability in the speed such as an air-operated cylinder is used for moving the sensor, in order to make the structure simple. In the case that detection is performed while the sensor is moved by such driving means, errors becomes large and it is difficult to detect wafers accurately. The present invention provides a wafer processing apparatus provided with a transmissive wafer detection sensor, a dog having index means and a transmissive sensor for the dog. The wafer processing apparatus calculates the ratio of the duration time of a signal from the transmissive wafer detection sensor and the duration time of a signal from the transmissive sensor for the dog corresponding to the index means and compares the ratio with a threshold value set in advance to determine the number of wafers.

In the present invention, for an NC program for controlling a machine tool, information for machining quality required by a machine tool is prewritten in the program. A measurement program for measuring the machining quality of the workpiece using a measuring machine is produced by analyzing the NC program. The machining quality of the workpiece is measured by the measurement program and the measuring machine. The machining quality of the workpiece can be judged by comparing the measurement results and the machining quality information included in the NC program. By utilizing this quality judgement, simple and effective system control can be achieved when a system such as CIM (Computer Integrated Manufacturing) is constructed in cooperation with other machine tools.

There is here disclosed a movement error compensating device for a movable unit such as a slider in a numerical control machine tool. A laser beam is emitted from a reference position beam generator installed on a fixed base in the movement direction of the slider. The slider is provided with a beam passing position detector, which detects a deviation on YZ planes of the laser beam. In order to properly detect the irradiation direction of the laser beam, the fixed base is equipped with a movement end beam position detector.

A method of simulation of NC machining, wherein machining simulation is carried out according to blank shape data, tool shape data and an NC program to modify the NC program or interpolation data by feedforward control so that optimum cutting conditions can be obtained. The simulation result can be used for correcting the NC program and the interpolation data at the next stage. Further, a record of tools used can be generated on the basis of this simulation result.

A method and system for determining the extent of deterioration of a bill includes generating transmitted and reflected light images. The reflected and transmitted light intensities of the transmission and reflection light intensity images are used to determine one or more disorder curve lengths for each image of the bill. Each disorder curve length is compared with a corresponding predetermined disorder curve length for a corresponding image of a reference bill to generate an evaluation factor. The positions of the evaluation factors on an evaluation map indicate the extent of deterioration of the bill.

A method of surface roughness measurement is disclosed which uses a fiber-optic probe having a sensor head constituted of a light-emitting fiber and multiple light-receiving fibers disposed coaxially with the light-emitting fiber. The surface roughness measurement includes the steps of: (a) pre-measuring a first correlation between detected intensity and gap distance for each of reference samples obtained under a plurality of different processing conditions; (b) searching a second correlation between maximum intensity and surface roughness for each of the reference samples, based on the first correlation, and storing the second correlation in memory; (c) adjusting the gap distance so as to set the probe in a position at which the maximum intensity is obtained for the reference sample machined under the processing condition to be monitored; and (d) monitoring the maximum intensity of the machined surface at the gap distance set in step (c), and determining the roughness of the machined surface based on the second correlation.

An automatic tape loading and unloading device for a magnetic tape recording and/or reproducing apparatus includes a cylindrical tape guide drum having at least one rotary magnetic head which moves in a circular path substantially coinciding with the circumferential surface of the drum. The tape used in the apparatus is stored on supply and take-up reels having the tape wound thereon in a tape holder such as a cassette or cartridge and in use the holder positions the tape supply at a relatively lower level with respect to the tape guide drum. The device further includes a first tape engaging member, for example, tape guide pins, carried by levers which are rotatable about a fixed pivot to draw the tape from the tape supply reel in a diagonally upward direction to the tape guide drum where it is helically wrapped about at least a portion of the circumferential surface of the drum and a second tape engaging member to draw the tape from the tape supply reel in a horizontal direction opposite to the direction of movement of the first tape engaging member.
