Patent JP-H10330514-A (JP)
Title: Production of prepreg
Inventor: IKETANI KUNIO
IPC: B29K105/08
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To minimize the generation of resin powder to thereby reduce defective moldings due to the powder in laminating and multilayer molding by impregnating base glass fibers with an epoxy resin varnish, cutting the prepreg to a necessary size, strongly pressing the end of the prepreg, and treating the end with a liquid that does not dissolve the epoxy resin and then with a liquid that dissolves the resin. SOLUTION: A pair of rotating rolls are used for strongly pressing the end of the prepreg. Water is preferably used as the liquid that does not dissolve the prepreg. Particularly, water containing little ionic impurities is used from the viewpoint of electrical reliability. An organic solvent (e.g. acetone) is suitably used as the liquid that dissolves the prepreg. Heating at 100 deg.C or higher is not necessary for drying. Hot air at 90 deg.C or lower is blown for drying to shorten the time of liquid treatment steps. This technique gives a prepreg which is most suitable for multilayer molding of an article flat all over the surface, without occurrence of ruggedness and waviness, and which scarcely generates resin powder from the cut sections, etc.

Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent the pressure variation of the blocking space in a dust sleeve when a sleeve yoke and a spline shaft are displaced in the axial direction, and to prevent the invasion of a muddy water into the blocking space. SOLUTION: In this propeller shaft, a shaft which consists of a hollow shaft (propeller shaft) 41 and a spline shaft 42, and a tubular yoke (sleeve yoke) 2, are engaged through a ball spline mechanism 5, and near the front end of the tubular yoke 2 is covered by a dust sleeve whose one side end is fixed to the spline shaft 42, while its other side end is sliding contacted to the outer peripheral surface of the tubular yoke 2. In this case, a blocking space G in the dust sleeve 6 is communicated to the inner space H of the hollow shaft 41 by a through hole 420 for air removing formed to the spline shaft 42. As a result, the pressure variation in the blocking space G can be prevented without opening the through hole 420 for air removing directly to the outer side.

Title: Production of diffraction grating
Inventor: MUROTANI YOSHIHARU
IPC: H01L21/027
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To improve the field junction accuracy of an electron beam exposing device and to improve the control accuracy of a diffraction trating pitch without being restricted by an electronic beam minimum unit moving distance by obliquely forming the diffraction grating at a certain inclined angle from the wafer stage moving direction of the exposing device. SOLUTION: In the case of exposing two parallel line patterns of which interval 13a is d1 , an angle 16 formed between the stage moving direction of the exposing device and an electronic beam scanning direction is set up as θ. The angle θ formed between a center line connecting grating points mutually separated by m columns and n rows and the row line becomes θ=tan m/n. The interval dm between parallel center lines passing grating points mutually separated by m columns becomes dm =m×do ×cos θ = m×do × n/√(m<2> +n<2> )} when the minimum unit moving distance (=minimum inter-grating point distance) of an electronic beam is set up to d. Since (m) and (n) are positive integers which are mutually prime, m×n parallel lines passing grating points can be drawn between two parallel lines.
