This mixture is pushed upward while being stirred and mingled by means of the screw conveyor 3 and a coil spring 4 so that the abrasive P absorbs dirt from the pin balls B. Then the mixture is discharged from the cylindrical member 1 onto an inclined separating drain-board, and falls down to a side slope where the abrasive P is separated and collected in a hopper from which the abrasive P is returned to a box 5 to recirculate through the polishing device. Meanwhile the pin balls are moved to pin ball game machines through a chute and a trough.

IPC: H01L21/027
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To make a plurality of level profiles during photoresist by a method wherein lights are directed to photoresist through first mask patterns and continuously lights are directed to photoresist through second mask patterns. SOLUTION: First, lights are passed through a photoresist layer 52 through first mask patterns, and exposure patterns 72 which received lights through an opening part of the first mask patterns are formed. Next, lights 90 having a second exposure level pass through mask patterns 85 of a reticle 88 and invade into the photoresist layer 52 to make second exposure patterns 100. The second exposure patterns 100 contain two regions 102, 104 corresponding to locations of opening parts 92, 94 of the reticle 88. Next, the photoresist layer 52 is developed. At this time, a greater amount of light are received in the regions 102, 104 than in the region 72 by two-time exposure, so that earlier development can be performed. By stopping developments at the time of development completion of the regions 102, 104, a photoresist mask of a desired shape can be made.

IPC: G01J5/48
Filed: 1992-03-16
Abstract: PURPOSE:To provide sensitivity characteristics, namely sensitivity deviation, of a plurality of photodetectors, by moving in the direction of the optical axis in an optical system, a light-receptor in which the photodetectors are juxtaposed. CONSTITUTION:An optical system 11 converges reflected rays of an observation object by a plane mirror 12 into a light-receptor 13, and a plurality of photodetectors within the receptor 13 output voltages proportioned to the intensity of light. On this, the receptor 13 is driven by a photodetector driver 55 and moved between the position 13b of the focal point of the system 11 and the position 13a shifted in the direction of the optical axis. In an observation mode, the receptor 13 is located in the position 13b of the system 11, and a focused image of the observation object is formed. In a calibration mode, on the other hand, the receptor 13 is shifted from the position 13b to the position 13a. An optical image inputted to the receptor 13 is fuzzy and extends over the whole surface in the case where the observation object for example is the sea, etc., small in irregularity of reflection characteristics, and the incident rays of photodetectors become almost uniform. Consequently, the parameters other than photodetector sensitivity in a specific equation of output computation of a radiometer can be used in common to each photodetector, and output data, namely sensitivity deviation data, corresponding to the sensitivity of each picture element of the light- receptor 13 are obtained.

Abstract: PURPOSE:To attain accurately the detection of corresponding point of an object on various conditions by detecting a corresponding point after forming a position having a change in contrast on the object by using an auxiliary means if the correspondence between corresponding positions is not accurate. CONSTITUTION:An image signal of the object 1 image picked up by different visual points by means of TV cameras 2, 3 is stored in memories 13 and 14. A processing circuit 15 detects a corresponding point between left and right pictures in the memories 13, 14 and when the detection of the corresponding point is not accurately obtained, the circuit 15 activates a pattern projector 17 being an auxiliary means. The projector 17 forms a prescribed pattern 18 caused by the change in the contrast of light on the object 1. Further, the distance is calculated to the corresponding point based on the image input by the cameras 2, 3 again so as to obtain the distance picture data. As a result, the data as to each point of the object image is stored in a memory 16 so as to form the distance picture relating to the object 1.
