| 20080224440 | Crank for Bicycle and Method of Producing the Same - A crank for a bicycle, excellent in production efficiency, excellent in fatigue durability and rigidly, and light in weight. The crank has an outer shell made of a fiber-reinforced plastic, a first insert member configured and arranged to introduce a load from a pedal shaft, and a second insert member coupled to a bracket spindle and configured and arranged to transmit a load to a sprocket. The outer shell comprises at least two fiber-reinforced plastic members at least a part of each of which is molded in advance. | 09-18-2008 |
| 20090047516 | CONDUCTIVE COMPOSITE FIBER AND METHOD FOR PRODUCING SAME - Provided is an electrically conductive conjugate fiber formed by conjugating an electrically conductive layer (A) including 60 to 80% by weight of a thermoplastic resin and 20 to 40% by weight of electrically conductive particles and a protective layer (B) including 50 to 95% by weight of polyethylene terephthalate and 5 to 50% by weight of polyethylene-2,6-naphthalate, wherein the fiber has a degree of elongation (DE) of 100 to 350%. This provides an electrically conductive conjugate fiber which exhibits a small change with time in physical properties such as a degree of elongation or boiling water shrinkage during its transportation or storage, while having a certain degree of elongation. | 02-19-2009 |
| 20090117800 | ELECTRICALLY CONDUCTIVE COMPOSITE FIBER AND PROCESS FOR PRODUCING THE SAME - An electrically conductive composite fiber comprising an electrically conductive layer formed of a polyester-based polymer (A) having a melting point of 200° C. or higher and containing from 23 to 33% by weight of electrically conductive carbon black, and a protective layer formed of a polyester-based polymer (B) having a melting point of 210° C. or higher, wherein the difference between the SP value of the (A) and the SP value of the (B) is adjusted to not greater than a predetermined value and the fiber strength and the elongation at break are adjusted within certain ranges. This can make it possible to obtain an electrically conductive composite fiber that has a superior antistatic performance, which is not degraded very much over a practical wearing for a long term, though it contains only a relatively small amount of electrically conductive carbon black, and that is suitable for the field of clothing such as clean room wears and working wears. | 05-07-2009 |
| 20090318049 | CONDUCTIVE SHEATH-CORE CONJUGATE FIBER AND PROCESS FOR PRODUCING THE SAME - In an electrically conductive sheath-core conjugate fiber including an electrically conductive layer made of a thermoplastic polymer (A) containing electrically conductive carbon black fine particles which constitutes a sheath component and a protective layer made of a fiber-forming thermoplastic polymer (B) which constitutes a core component, the ratio of the (A) to the total weight of the (A) and the (B) is 10 to 35% by weight, the L | 12-24-2009 |
| 20100178487 | PREPREG AND CARBON FIBER REINFORCED COMPOSITE MATERIALS - A prepreg containing a carbon fiber [A] and a thermosetting resin [B], and in addition, satisfying at least one of the following (1) and (2).
