Title: Rotary ring-one side belt type continuous casting device
Inventor: NIIYAMA EISUKE
IPC: C08F290/06
Filed: 1980-06-04
Abstract: PURPOSE: To make continuous casting possible at high speeds without increasing the size of a rotary ring by forming notches having a prescribed gradient along the mutually opposing lateral circumferential edge parts of the rotary ring.  
     CONSTITUTION: Molten metal which is continuously supplied from a molten metal pool 14 is spouted from a nozzle 15, and is pressed into a moving mold. At this time, a rotary ring 4 and an endless belt 7 are cooled by water. Hence, the molten metal pressed to the inside of the moving mold beings to solidify from the opposite circumferential edge parts of the ring 4 and the parts in contact with the belt 7. The central part thereof turns into the state that is contains unfrozen molten metal. When this striplike ingot detaches from the moving mold, it is fed into between rolls 12 and 13, and further the ingot 17 moves while being placed on the belt 7 moving on a horizontal plane. Since the solidified shell of the ingot 17 arriving at around a roll 8 has sufficient strength, there is no possibility of leaking of the unsolidified molten metal on account of bending deformation or cracking.

IPC: H01J37/244
Filed: 1982-04-30
Abstract: PURPOSE:To obtain an electron microscope device in which the contraction rate of a beam can be increased, the beam diameter can be made small while maintaining beam current high and any curve or distortion of the beam can be prevented. CONSTITUTION:A pair of secondary-electron detectors 10a and 10b are installed symmetrical relative to the center axis of a mirror body 1a. A cylindrical secondary-electron decelerating electrode (called a secondary electrode hereafter) 29 is used and installed inside an objective lens 7. The above pair of detectors 10a and 10b are positioned above the secondary electrode 29 and the objective lens 7, and detect secondary electrons B2 deflected and decelerated with the secondary electrode 29, the secondary electrons B2 then being applied to a common video amplifier. Owing to such a constitution, alphas can be made large by decreasing working distance, thereby enabling the beam diameter to be made small while maintaining the beam current at a high level. Besides, there is no possibility that a beam (B1) is curved or distorted by secondary-electron-drawing voltage applied to the detectors 10a and 10b.
