Title: Method for producing precursor fiber bundle of polyacrylonitrile-based carbon fiber, and precursor fiber bundle of polyacrylonitrile-based carbon fiber obtained by using the same
Inventor: ZUSHI HIROAKI
IPC: D01F6/18
Filed: 2011-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a precursor fiber bundle of a PAN-based carbon fiber capable of maintaining or improving a quality of a PAN-based fiber bundle to be obtained, in a high speed spinning process for the PAN-based fiber bundle.SOLUTION: A PAN-based polymer is spun at high speed by a wet spinning method or a dry-wet method using a coagulation bath. In a coagulating step of production of a PAN-based fiber bundle, when a fiber bundle is drawn while being coagulated, a strain speed in a liquid of a coagulated fiber bundle is set in a range of 4.0×10to 10.0×10(sec). When the fiber bundle is drawn while being coagulated, the temperature of a coagulation liquid is preferably 10 to 40°C. Owing to this construction, the solvent of the PAN fiber bundle is sufficiently removed at high speeds, and is dried and drawn by a known method to form a precursor fiber bundle of a PAN-based carbon fiber. The PAN precursor fiber bundle has 20 ppm or less of an amount of average residual metallic impurities, and 7.5% or less of a CV-value thereof.

Title: Lighting fixture
Inventor: MATSUSHIMA AI
IPC: F21V7/00
Filed: 2011-04-25
Abstract: PROBLEM TO BE SOLVED: To control light distribution so as to widen an irradiation range in one direction, while controlling deterioration of utilization efficiency of light and glare.SOLUTION: Since the light distribution in a short length direction is narrowed as a second reflection surface 31 of a light distribution part 3 is formed in a concave surface, the lighting fixture can irradiate light efficiently as compared with the case in which the second reflection surface 31 is a plane. Furthermore, since a third reflection surface 32 is formed in a concave surface rather than a plane parallel to the perpendicular direction (optical axis direction of a light-emitting diode), the light reflected by the third reflection surface 32 hardly enters into a 'glare zone', and as a result, the glare can be controlled. Further, in this embodiment, an inclination angle of the third reflection surface 32 is made close to perpendicular as compared with that of a first reflection surface 30, a degree of the irradiation range becoming narrower can be reduced as compared with the case in which the third reflection surface is of a perpendicular plane.

Abstract: PROBLEM TO BE SOLVED: To automatically measure a pitch of components aligned on a tray of a tray feeder.SOLUTION: A mark camera 18 is moved immediately above a center position of a leading component on a tray to pick up an image of the leading component. After the picked-up image is stored in a storage device as a reference image, images are continuously picked up while the mark camera 18 is moving in an alignment direction of the components. A correlation value of the picked-up image and a reference image stored in the storage device 14 (the picked-up image of the leading component) is calculated for each image pick-up, to store data of the correlation value in the storage device 14 in time series. When a moving amount of the mark camera 18 exceeds a width of the tray, movement and the image pick-up of the mark camera 18 are completed, to analyze time-series data of the correlation value stored in the storage device 14 and search a peak point of the correlation value. The moving amount of the mark camera 18 between the peak points of the correlation values for one cycle of variation of the correlation value is calculated, and the calculated value is stored in the storage device as a component pitch.
