  • Publication number: 20120302118
    Abstract: A sheet for a fiber-reinforced resin according to the present invention includes a conjugate fiber that contains a low melting point polymer component and a high melting point polymer component. The low melting point polymer component and the high melting point polymer component are polymers of the same type. When the sheet is formed into a fiber-reinforced resin molded article, the low melting point polymer component serves as a matrix resin, while the high melting point polymer component serves as a reinforcing fiber. The conjugate fiber is arranged in at least one direction. A fiber-reinforced resin molded article according to the present invention is obtained by heating the sheet for a fiber-reinforced resin to a temperature equal to or higher than the melting point of the low melting point polymer component and lower than the melting point of the high melting point polymer component, followed by compression molding.

  • Patent number: 5199937
    Abstract: A centrifugal separator able to function as an agitator. A motor controlled by a control box drives a disk-like rotor. For agitation, the motor makes the rotor intermittently rotate, and for centrifuging, the motor makes the rotor constantly rotate. The rotor has a pair of pins which are extended in a tangential direction to the rotation of the rotor. A bucket for accommodating a sample container is freely swingably supported by a pair of pins. During the alternate repeat of the rotation and stopping of the rotor, the bucket with the sample container performs regular swing like a pendulum in the radial direction of the rotor. The rotation of the rotor and the swing of the sample container generate a smooth circular flow of the liquid content in the sample container.

  • Patent number: 5023288
    Abstract: The silicone rubber adhesive film of the present invention is characterized by simplicity of handling and an excellent workability and useablility, as well as by adhesiveness for various types of substrates and an excellent durability of adhesion. These characteristics are obtained because the silicone rubber adhesive film of the present invention comprises a silicone rubber composition which consists of components (A) through (G), particularly the specific wet-method hydrophobicized reinforcing silica comprising component (C) and the specific compounds of components (D) and (E) or components (D), (E), and (F), and because the tensile strength of said uncured silicone rubber composition falls within the range of 1.5 kg/cm.sup.2 to 5.0 kg/cm.sup.2 at 25 degrees Centigrade (JIS K 6301). Accordingly, when used on flat substrates such as textiles, glass, rubber sheet, etc., it can tightly bond the adhered partners into a single, integral body.
