Filed: 1988-06-22
Abstract: PURPOSE:To make it possible to separate a semiconductor chip favorably from a resin sheet without damaging the semiconductor chip and the resin sheet by arranging the constitution wherein the semiconductor chip can be pushed up in order at multistage from a push-up body positioned on the outer periphery. CONSTITUTION:As a push-up means 10, the one constituted of plural push up bodies 11-14 which are arranged such that the centers of the figures may be aligned from the outer periphery side to the inner periphery side is adopted. And when separating a semiconductor chip 2, the semiconductor chip 2 is pushed up more upward in order at multistage from the push up body at the outer periphery side. As a result, since the semiconductor chip 2 comes to be stripped of sheets 1 by degrees from the end on the outer periphery, concentrated loads are never added to one part of the semiconductor chip 2, and exfoliation of the sheet 1 from the semiconductor chip 2 can be done smoothly. Hereby, it comes to be stripped while always keeping horizontal direction without damaging the semiconductor chip, nor tearing the sheet.

Filed: 1991-06-26
Abstract: PURPOSE:To spread a hard coat material or protective coat material to a uniform coated amt. and to prevent unequal coating by applying the hard coat material or protective coat material on an optical disk from its middle periphery to the inner periphery to a uniform amt. while rotating the optical disk at a low speed, then stopping the rotation for a specified period of time and thereafter, rotating the disk at a high speed. CONSTITUTION:After a substrate 1 is set on a turn table 6 for spin coating, the hard coat material 7 is ejected from a nozzle 8 for applying the hard coat material under rotation at a low speed of 60rpm. The nozzle 8 is moved at 1mm/sec speed from the position of 29mm radius from the center of the substrate 1 to the position of 23mm radius and the coat material 7 is ejected under 0.4kgf/cm<2> pressure. The rotation is thereafter stopped for 4 seconds to naturally spread the coat material 7 and the coat material 7 is uniformly spread over the entire surface of the substrate 1 by the high-speed rotation of 6000rpm. The coat material is irradiated with UV rays 9 and is thereby cured. The nonuniformity of the coated amt. of the coat material 7 is eliminated in this way, by which the unequal coating is prevented and the yield is improved.

Abstract: PROBLEM TO BE SOLVED: To lengthen the lifetime of a frame, and to prevent the overturn accident of an execution car due to the damage of the frame by extending a plurality of each core material in the horizontal direction while laminating the mutually superposed core materials by adhesive layers in the main body of the frame. SOLUTION: Core materials 21A constituting the main body 21 of a supporting panel 20 for the frame 10 for the execution of works and the main body of a slope panel are laminated by adhesive layers 21B, and the adhesive layers 21B function as slip induction joints. Accordingly, when excessive bending stress works to the frame 10, the core materials 21A mutually slip through the adhesive layers 21B, and each of the core materials 21A is deflected and the whole frame 10 is deformed elastically. The slip induction joints corresponding to bending stress are formed among the superposed core materials 21A by using the adhesive material of the adhesive layer 21B having shear strength of 1.0 kg/cm2 or more and elongation of 100% or more at that time. A butyl rubber tape is used as the adhesive layer 21B, and material characteristics can be maintained stably for a prolonged term.  Consequently, the lifetime of the frame 10 for the execution of works is lengthened, and the execution of works can be conducted safely.
