Title: Resist material
Inventor: TANIGAKI KATSUMI
IPC: H01L21/027
Filed: 1983-06-02
Abstract: PURPOSE:To obtain a resist material having high sensitivity to ionizing radiation, such as X-rays, gamma-rays, or electron beams, by using a polymer made from a specified trioxaspiro compd. as a structural unit, and having a specified weight average mol.wt. CONSTITUTION:A trioxaspiro compd. represented by the general formula shown here where (n) is an integer of 1-5 is high in sensitivity to ionizing radiation, and a copolymer of this unit and ethyl acrylate unit or the like rises in sensitivity as compared with the original ethyl acrylate homopolymer. Since the rise of sensitivity means that a necessary amt. of exposure is small, it can shorten exposure time. Sensitivity to ionizing radiation, such as electron beams and X-rays, rises as its mol.wt. increases, and when it has a mol.wt. of <=1,000, its sensitivity becomes insufficient, and when >=1 million, resolution is lowered by swelling occurring during development, and further, problems occur also in respects of solubility and coating performance. therefore, preferable mol.wt. of the copolymer is 1-1,000 thousand, and the best resist material can be obtained above all when the polymer has a weight average mol.wt. of 10-1,000 thousand.

IPC: B23Q7/00
Filed: 1985-05-13
Abstract: PURPOSE:To aim at surely discharging a short pipe which may not be discharged by rollers alone, by providing actuators for moving, in the axial and radial directions of a material, a bore section holder supported movably in the pipe-axial direction by means of a holder movable in the pipe-diametrical direction, and also by providing a pipe discharge means. CONSTITUTION:When a pipe P has a length which is less than a predetermined length 11, the gravity center of the pipe P comes to be nearer to a working machine body than the front most roller 57B, and therefore, the pipe P may not be fed even though the roller 57B is rotated. In this arrangement, a retaining roller 151 which is rotatably journalled to a roller receiver 153, is elevated together with the roller receiver 153 by means of a cylinder 157, and therefore, the roller 151 comes to be a position right above the roller 57B to transmit rotation to the pipe P. Further, if the length of the pipe P is less than 12 and therefore the front end of the pipe P does not reach the roller 57B, an insertion rod 161 is inserted until its front end pierces through the pipe P, and after being moved upward to be made in contact with the upper surface of the bore of the pipe P, the chuck is released so that the pipe P is held on the insertion rod 161, thereby it is possible to discharge the pipe P only by pulling out the rod 161.
