Abstract:
Provided is an active energy ray curing resin composition for seal-material use that has high geometrical precision, has outstanding productivity, and is favorable for use in a bead-shaped seal material. In this active energy ray curing resin composition for seal-material use, at least 0.1-25 parts by weight of a thixotropy-imparting agent (B) is dispersed in 100 parts by weight of an active energy ray curing resin (A), the apparent viscosity (compliant with JIS Z8803, cone/plate rotating viscometer, 40°C) of the active energy ray curing resin composition in an uncured state is 50-5000 Pa.s in the 0.1-10/sec shear velocity range, the thixotropic factor as determined on the basis of the apparent viscosity in the shear velocity range is 1.1-10, the thixotropy-imparting agent (B) is silica microparticles, and the particle size distribution of the silica microparticles in the active energy ray curing resin (A) has a plurality of peaks.
Abstract:
PROBLEM TO BE SOLVED: To provide a cushioning material having novel cushioning action and visual effect as well as a guiding function of centroid shift, and also to technically develop a shoe equipped with this cushioning material. SOLUTION: This is a member for cushioning impact by being incorporated in a cushion requiring base material and by being elastically deformed. The member is integrally includes a heel pressure portion 2 and a deformationed portion 3 that develops in a fan shape around the heel pressure portion 2. In the deformed portion 3, a degree of deformation when a load is received is adjusted by forming a thickness reduced portion 5 in the depth direction. The thickness reduced portion 5 is structured so as to be seen through from an exposed surface 30. Because the deformation requiring part 3 has a shape developed in a fan-shape, when it is deformed with a load-imparted part depressed, the deformation takes place with both ends of the part raised, so that cushioning action is produced by springiness in the width direction of the deformation requiring part 3. Further, such deformed state of the deformation requiring part 3 can be visually recognized from the outside as the deformation of the thickness reduced part 5. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a novel buffer part exhibiting excellent buffering properties (shock absorbing properties) and capable of controlling the properties and its manufacture method. SOLUTION: The buffer part 1 is provided with a flexible casing 2, a super deformation absorbing body 3 housed inside it and functioning mainly as a shock absorbing material with a 500% or greater elongation and a deformation allowing part structure 4 for releasing a compressive load applied to the part 1 as an expansive deformation of the body 3 in a direction approximately orthogonal to the load direction. On a boundary face between the body 3 and the casing 2, at least a part is fixed. Thereby when the compressive load is applied to the part 1, the expansive deformation of the body 3 in the structure 4 absorbs the load and makes the body 3 recover an original figure after the release of the load.
