Crossbow riser / Hunter's Manufacturing Co., Inc. Provided is a crossbow riser that may comprise a plurality of cells defined by walls. The walls may consist essentially of a material wherein the yield tensile strength at 0.2% strain is greater than 780 MPa, and either the specific strength is greater than 200 kN·m/kg, or the density is less than 6.0 g/cc. The cells may collectively define a first volume. The walls may collectively define a second volume. The ratio of the first volume to the second volume may be greater than 1.5. |

CRIMPED YARN HAVING FLAT CROSS-SECTION, METHOD OF MANUFACTURING SAID CRIMPED YARN, AND TEXTILE COMPRISING SAID CRIMPED YARN / MITSUBISHI CHEM CORP The problem addressed by the present invention is the provision of a crimped yarn having a flat-shaped fiber cross-section and exhibiting a superior crimp rate CC, the provision of a method of manufacturing said crimped yarn at a superior throughput, and the provision of a textile exhibiting superior insulation and coolness even if the density or basis weight is reduced. The problem addressed by the present invention can be solved by: a crimped yarn constituted by a multifilament having a cross-sectional shape with a planarity of 2.0?5.5 and a crimp rate CC of 15?60% in a cross-section perpendicular to the fiber axial direction of the unit fibers; manufacturing a crimped yarn by performing a false twist process, at a false twist coefficient of 16,000?42,000, upon a multifilament having a cross-sectional shape that includes hollow sections in a cross-section perpendicular to the fiber axial direction; and a textile that contains 50?100% by mass of a crimped yarn constituted by a multifilament, has a woven density of 0.40 g/cm3 or less, and has a transmittance of 33% or less for visible light having a wavelength of 400?780 nm, 50?100% by mass of the unit fibers that constitute the multifilament having a flat shape in a cross-section perpendicular to the fiber axial direction, and the planarity of the flat shape being 2.0?5.5. |

METAL HALIDE LAMP FOR RAISING AND ENJOYING WATER GRASS / IWASAKI ELECTRIC CO LTD PROBLEM TO BE SOLVED: To provide a metal halide lamp of low wattage usable for both raising and enjoying a water grass in common, and formed to contain luminescence necessary for the photosynthesis of the water grass including almost all types of seaweeds, and have a color rendering evaluation number Ra equal to or above 80. SOLUTION: A light emitting tube 1 of 0.6cc content volume having electrodes sealed to both ends, and containing 1.6mg of dysprosium iodide, neodymium iodide and cesium iodide respectively sealed to a ratio of 2:1:2, 7mg of mercury, and 1.33×104 Pa of argon gas, and a protection sleeve 2 arranged outside the light emitting tube 1 are built into an outer tube 5, thereby forming a lamp. Then, the lamp is vertically laid to form a metal halide lamp 11 usable for raising and enjoying a water grass, so as to have radiation energy equal to or 35% at wavelength between 380nm and 495nm among radiation energy in a visible zone, radiation energy equal to or above 30% at wavelength between 600nm and 780nm, and Ra equal to or above 80. |
