    Abstract: PURPOSE:To obtain the subject new fiber, containing crystalline and amorphous carbon and silicon-carbon-oxygen substances in a specific proportion as components and excellent in oxidation resistance and wettability for plastics with a high electric conductivity and a small thermal expansion coefficient. CONSTITUTION:The objective fiber is obtained by mixing (A) an organosilicon polymer prepared by heating dimethylchlorosilane, etc., in an inert gas with (B) a polycyclic aromatic compound such as petroleum-based pitch, reacting both at, e.g. 250-500 deg.C, providing a random copolymer, mixing the resultant random copolymer with (C) a polyacrylonitrile-based polymer, spinning the prepared mixture and then infusibilizing and burning the spun fiber. The aforementioned fiber contains crystalline carbon in which condensed aromatic rings are elongated in the fiber axis direction, crystalline carbon in which the turbostratic structure is not agreement with the fiber axis direction, amorphous carbon and aggregates, composed of ultra-fine particles having

    Abstract: PURPOSE:To obtain a light racket frame with high rigidity and a satisfactory hitting feeling by composing the racket frame of a fiber reinforced resin for which a specified reinforcing fiber is used. CONSTITUTION:The racket frame is formed while being composed of the fiber reinforced resin for which C-SiC fiber and/or C-SiC-MC (M is one kind at least to be selected out of a group composed of Ti, Zr and Hf) is used. The fiber is inorganic fiber to be obtained from Si included polycyclic aromatic polymer and the constituting component is a amorphous phase practically composed of Si, C and O and/or crystalline ultrafine-grains practically composed of beta-Si which grain diameter is less than 500Angstrom and an aggregate composed of amorphous SiOx(0

    Abstract: PURPOSE:To pulverize a refrigerant injected from nozzles for jetting the refrigerant finely, and to improve the efficiency of heat exchange, by a method wherein a rotary drum with the nozzles in revolved at high speed in a box body to which brine is filled. CONSTITUTION:A rotary drum 9, to whose circumferential surface nozzles 10 are mounted in projecting shapes, is arranged to a lower portion of a crystal pan 1. One end of shafts 12 of the rotary drum 9 is hollowly formed, and connected to a conduit 5 of a liquefied refrigerant through a rotary joint 15. A pulley 16 is fixed to the other outer end of the shaft 12, and a belt 19 is stretched between the pulley 16 and a pulley 18 fastened to an output shaft of a motor 17. The liquefied refreigerant dispersed as minute particles from the nozzles 10 deprives brine of heat, evaporates and floats, and is discharged from a discharge port 6.

    Abstract: PURPOSE:To form a golf club head having a face insert excellent in repulsion properties and durability by using either one of two kinds of specific fibers as the reinforcing fiber of the face insert. CONSTITUTION:In a golf club head consisting of a face insert 1 made of a fiber reinforced resin, a core 2 and a sole plate 3, the reinforcing fiber of the face insert 1 is composed of a C-SiC fiber and/or a C-SiC-MC fiber (M is at least one element selected from a group consisting of Ti, Zr and Hf). The C-SiC fiber and the C-SiC-MC fiber shows excellent resin adaptability, for example, good wettability and adhesiveness as compared with a conventional carbon fiber by SiC and MC finely dispersed in the fiber in spite of high strength and high elasticity. Therefore, the face insert 1 composed of a fiber reinforced resin containing the inorg. fiber as a reinforcing fiber shows excellent repulsion properties and durability.

    Abstract: PURPOSE:To obtain the title shaft with a good torsion-characteristic and with a high shock-resistance, by a method wherein the reinforcing fiber for a tubular shaft consists of C-SiC fiber and/or C-SiC-MC fiber (M is selected from among elements of Ti, Zr and Hf). CONSTITUTION:For a tubular shaft made of fiber reinforced resin, its reinforcing fiber consists of C-SiC fiber and/or C-SiC-MC fiber (M is at least one element selected from among a group of elements of Ti, Zr and Hf). The C-SiC fiber is an inorganic fiber obtained from a polycyclic aromatic polymer containing silicon, and the C-SiC-MC fiber is another inorganic fiber obtained from the polycyclic aromatic polymer containing metal, the polymer of which contains at least one element selected from among a group of elements of titanium, zirconium and hafnium, and silicon. Although these C-SiC fiber and C-SiC-MC fiber have high strength and high elasticmodulus, they have excellent plastic compatibility owing to SiC and MC which are finely scattered in the fiber. In this way, a good torsion-characteristic and high impact-resistance is given to the title shaft.
