Methods for manufacturing a panel for a ball, in particular for a soccer ball, as well as panels manufactured by these methods and balls with such panels. A method comprises the following steps: providing a carrier material having an outer side and an inner side within a mold having at least one first and at least one second mold part. Three-dimensionally molding an outer layer of the panel on the outer side of the carrier material within the mold. Three-dimensionally molding an inner layer of the panel on the inner side of the carrier material using at least the first mold part.

A concrete form clip includes a main clip body, a first channel, a second channel, and at least one anchoring feature so that the concrete form clip can receive a form mat and secure to the ground surface. The first channel is terminally connected to the main clip body from top, and the second channel is terminally connected to the main clip body from bottom. As a result, the main clip body, the first channel, and the second channel are able to receive the form mat. The concrete form clip can be secured to the ground surface with the at least one anchoring feature through a wooden stake and/or a metal stake. The form mat and multiple concrete form clips collectively delineate the section shape of the area that concrete is poured.

An object of the present invention is to provide a golf ball striking a good balance between flight distance on driver shots and spin rate on approach shots, and excellent in stain resistance and shot feeling. The present invention provides a golf ball comprising a paint film, wherein a base resin of the paint film contains a polyurethane obtained by a reaction between a polyisocyanate composition and a polyol composition containing a urethane polyol having a polyether diol with a number average molecular weight in a range from 800 to 3,000 as a constituent component, and the following requirements are satisfied: Mp≦200×X−75 Mp≦100 Minm−Moum>40 Moum−Mc Tc>Tp (Tinm×Minm)/(Toum×Moum)>2.0 (Toum×Moum)/(Tc×Mc) 10.0 [where Mp, Minm, Moum, and Mc represent a 10% elastic modulus (kgf/cm2) of the paint film, inner intermediate layer, outer intermediate layer and cover, respectively; Tp, Tinm, Toum, and Tc represent a thicknesses (mm) of the paint film, inner intermediate layer, outer intermediate layer and cover, respectively; and X represents a molar ratio (NCO/OH) of a NCO group in the polyisocyanate composition to a OH group in the polyol composition.].
摘要:
A stacked composite material having at least one glass fiber layer, at least two nanocomposite layers comprising multi walled carbon nanotubes dispersed in an epoxy matrix. Each glass fiber layer is sandwiched between two nanocomposite layers and the glass fiber layers are oriented in a unidirectional or a quasi-isotropic orientation with respect to adjacent and non-contiguous glass fiber layers in the stacked composite material. A method of preparing a stacked composite material comprising applying a nanocomposite layer onto a mold, overlaying a glass fiber layer on top of the nanocomposite layer, rolling an aluminum roller over the glass fiber layer, repeating the applying, overlaying, and rolling to form a stacked composite material.

A thermosetting resin molded article including: a metal member; a first thermosetting resin layer containing a chelating agent in an amount of 0.5% by mass or more; and a second thermosetting resin layer containing no chelating agent or containing a chelating agent in an amount of less than 0.5% by mass, in which the metal member, the first thermosetting resin layer, and the second thermosetting resin layer are stacked in this order is provided. A semiconductor device including: a semiconductor element mounted on a substrate and metal members, which are sealed with a sealant, in which the sealant includes: a first thermosetting resin layer stacked on the semiconductor element and the metal member; and a second thermosetting resin layer stacked on the first thermosetting resin layer is also provided.
摘要:
An optic can manage light emitted by a light emitting diode. The optic can comprise a backside that faces the light emitting diode and a front side opposite the backside. The front side can be convex. The backside can have a central region that is adjacent the light emitting diode and that is either concave or convex. One or more grooves can extend peripherally about the central region. An injection molding system can produce optics in which the backside comprises the concave central region as well as optics in which the backside comprises the convex central region. The molding system can utilize one molding member shaped according to the front side of the optic. That molding member can be compatible with two other molding members that are shaped according to the different backsides of the optic. Thus, two different optic forms can be produced with three molding members.
