This aims to provide a porous filter cartridge which is hardly contaminated, which is advantageous in the cost aspect, and which can perform efficient filtration and extraction without any breakage. The porous filter cartridge includes a porous filter retained in the bottom and inside of a bottomed cylindrical cap 5 having a discharge opening 29 formed in the center of the bottom. A plurality of ribs 35, 37 and 39 for supporting the porous filter are erected radially around the discharge opening 29 in the bottom of the cap 5. At least any of those ribs is connected across the discharge opening 29 at the central portion of the discharge opening 29, and a protruding face 41 protruding toward the porous filter is formed on the crest face of a connected rib portion 43.

A photobioreactor comprising a sealed, covered plastic sheeting coated with a thin layer of a highly dense culture of photoautotrophic single celled organism. Carbon dioxide is exchanged from a gas space above the culture through attendant mixing by subtending wave motion. The photobioreactor provides a substantial improvement in processing costs in growth media sterilization as well as reduced expenses related to energy and raw materials, especially carbon dioxide. Capital expenses are reduced by eliminating the need for sparging and compressors for suspending cells and mixing carbon dioxide.

To select a shoulder-tap method or a set of methods that optimizes the delivery of a shoulder-tap with respect to feasibility, reliability, and cost, in accordance with the present invention. Each shoulder-tap method can be evaluated on its feasibility, reliability and cost. A shoulder-tap method can be selected and used that optimizes reliability and cost with respect to feasibility constraints.

The present invention discloses an arched steel fiber for reinforcement of a cement-based material, of which a main body is arched in a length direction and opposite ends of the main body are curved such that the steel fiber has a higher pullout resistance strength compared to a conventional steel fiber, thereby improving mechanical performance such as a tensile strength, a flexural strength, an energy absorption capability, and the like of a cement compound. In addition, compared to a conventional art, a mixing amount of steel fiber to performance can be reduced so that an added economic value in terms of consumable cost can be created.

The present invention relates to a method for pretreatment of molten iron, which uses a single converter type refining furnace to continuously perform desiliconization and dephosphorization of molten iron with an intermediate slagging process, in which a sufficient amount of The slag is quickly discharged out of the furnace, and sufficient dephosphorization treatment can be performed in terms of cost and quality. The pretreatment method of the present invention includes: a desiliconization treatment process, supplying a gaseous oxygen source to the molten iron (5) in the converter type refining furnace (1) from a top blowing lance (2) to desiliconize the molten iron; a slagging process, At least a part of the slag generated in the desiliconization process is discharged from the converter type refining furnace; in the dephosphorization process, after the slagging process, a CaO-based flux is added to the converter type refining furnace, and a gaseous oxygen source is supplied from the top blowing lance , dephosphorize the remaining molten iron, wherein, in the desiliconization process, the slag height in the furnace is measured, and the measured slag height is defined by the distance from the molten iron bath surface in the furnace to the furnace mouth The desiliconization process is completed in a state where the height ratio of the melting chamber in the furnace is in a predetermined range.

The invention relates to a lighting device and a lighting tool. A semiconductor light-emitting element favorable for the cost aspect is used as the light source. The lighting device (10) comprises a thermal-conductive main body (13) with a substrate support part (13e) at one end; a substrate (14) provided with the semiconductor light-emitting element (11) and arranged on the substrate support part of the main body; a conductive wire-winding pin (15) arranged on the substrate and connected with the semiconductor light-emitting element (11); a lighting device (12) housed in the main body and lighting the semiconductor light-emitting element; a conductor for power supply (16) with one end connected with the lighting device and another end winded and connected with the wire-winding pin; a light seat part (17) arranged at another end side of the main body and connected with the lighting device. The lighting tool comprises a tool main body with a socket and the lighting device mounted on the socket of the main body. The cost is effectively reduced.

Provided is a haulage vehicle having an air cleaner that is realistic from the viewpoints of fabrication steps and cost aspect. An air cleaner (24) arranged in a haulage vehicle is provided with a swirling flow generator (26), a separator (27) and an outer cylindrical casing (25). The swirling flow generator has a fixed shaft (28) and a plurality of guide blades (29) arranged and shifted from one another over a predetermined angle in a direction in which the guide blades rotate about the fixed shaft, and by the plurality of guide blades, a swirling flow of cooling air is generated. The separator has a flange (32) attached on and along an inner peripheral wall of the outer cylindrical casing (25), an inner cylindrical member (30) arranged on an outer edge of a center bore of the flange, and a collection pocket (31). Dust contained in the cooling air is taken by the swirling flow into a space between the inner cylindrical member and the outer cylindrical casing and is allowed to accumulate in the collection pocket.

The invention relates to a loop wheel with a detachable wearing layer. The loop wheel is characterized by comprising a guide wheel shaft, wherein a bearing is mounted on the guide wheel shaft; a check ring is arranged on the upper part of the guide wheel shaft; the check ring is used for fixing; the loop wheel further comprises a positioning sleeve; the bearing is mounted in the positioning sleeve; a first end cover and a second end cover are respectively arranged at upper and lower ends of the loop wheel. The design is more suitable for the rolling of high-speed wire rod products; the exchanging times of the loop wheel can be greatly reduced; the steel ratio is increased; the yield in one shift is greatly promoted; the labor intensity of on-site workers is relieved; the production is stabilized; at the cost aspect, only the worn sleeve is exchanged, and the other parts can be repeatedly used, so that the cost of spare parts is greatly reduced.

A carbon nano-tube electrode suitable for mass production and favorable in the cost aspect. Its production method is also disclosed. When the carbon nano-tube of catalyst particles on an endless belt reaches from a chemical vapor deposition zone to a transfer zone by the movement of the belt, and is gradually collapsed horizontally as the tube is turned around the outer side of a driven drum, the carbon nano-tube is pressed against a conductive film from a tip thereof. The conductive film is fed downwardly from a film feeder, and heated by a heater to the temperature not lower than the softening point and not higher than the melting point. By pressing the carbon nano-tube against the conductive film, the carbon nano-tube is transferred to a surface of the conductive film from the catalyst particles in a substantially perpendicular manner.
