IPC: B21D37/20
Filed: 1989-09-27
Abstract: PURPOSE:To make slipping of work better when forming and to improve formability by forming at least one of the 1st formed surface of products, the 1st hold-down surface, the 2nd formed surface of products and the 2nd hold-down surface like roughened surface with cutting marks due to cutting. CONSTITUTION:The end part of the work W is inserted and held with the 1st hold-down surface 1b of an upper die 1 and the 2nd hold-down surface 2b of a lower die 2. The upper die 1 is pushed down to the position of bottom dead center against the lifting force of a die cushion with which the 2nd hold- down surface 2b is energized upward and the work W is inserted and held between the product forming surface 1a of the upper die 1 and the product forming surface 2a of the lower die 2 and is press formed. Because the contact with the work W is made into point contact or tine contact by forming the surface of the product forming surfaces 1a, 2a and the hold-down surfaces 1b, 2b into rugged roughened-surface-like due to cutting marks, slipping resistance is made in smaller and the work W is extended over all width. Therefore, slipping-in is improved and press formability can be improved.

Abstract: PURPOSE:To restrain the shearing of resist and to obtain an exposure device with which a highly reliable pattern can be formed by a method wherein an irradiation light is projected in such a manner that the gas generating from the resist on an irradiation section is controlled at the level with which the resist will be separated from a substrate, or less. CONSTITUTION:In an exposure device, with which a resist pattern is to be formed by projecting an irradiation light on the resist formed on a semiconductor substrate 6, it is arranged that the irradiation light, the intensity of which is controlled in such a manner that it is brought to the level at which the resin is separated from the substrate 6 by the gas generated in the resist 7 on the part of irradiation, is projected on the resist. For example, a filter 15, which changes its transmittance by stages, is provided between a condensing lens 2 and a shutter 4. Then, the intensity of exposure can be increased gradually against the filter 15 at the prescribed speed from right side to left side as shown in the diagram when exposed. At the same time, the total quantity of nitrogen gas generated by the optically reflected resist 7 is prevented from becoming as high as the shear level of the resist 7.

Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for filling a culture medium into a seedling-raising pot, even if the expansion of the culture medium has a slight variation, and allowing the good growth of the seedling by adding water to a compression-molded culture medium charged in the seedling-raising pot to expand the culture medium in a larger height than the proper culture medium height of the seedling-raising pot, and subsequently pressing the expanded culture medium to give the proper culture medium height. SOLUTION: This method for charging a culture medium into a seedling-raising pot 5 comprises charging the compression-molded culture medium into the seedling-raising pot 5, adding water to the charged culture medium to expand the culture medium in a larger height than the proper culture medium height H2 of the seedling-raising pot 5, and subsequently pressing the expanded culture medium to give the proper culture medium height H2. The compression-molded culture medium is preferably charged into the seedling-raising pot in a posture that the compression direction is vertical. Peat moss is preferable as a material for the culture medium. Before compression-molded, the peat moss is preferably subjected to the adhesion of particles such as bentonite to the surfaces of peat moss fibers to improve the water-absorbability of the fibers.  The expanded culture medium may be pressed by the rolling of a sowing hole-forming roll on the culture medium. Thus, the compressed culture medium can properly be charged into the seedling-raising pot, and sowing holes can simultaneously be formed.
