Abstract: Disclosed is a resin sliding member, including: 0.5 to 25 vol % of calcium fluoride dispersed as particles; and a synthetic resin as a remainder. The calcium fluoride is crystalline, and a peak intensity of a (111) plane of the calcium fluoride exposed on a sliding surface is larger than a peak intensity of a (220) plane.

Abstract: The conventional holding mechanism for foldable side rails have such problems that the release lever can be accidentally pressed for release action and that if a double lock is employed for preventing it, automatic holding action cannot be performed.

Abstract: A biomass gasification system and operating method thereof are able to prevent hindrances caused by the tar component in a fuel gas and to thermally utilize a fuel gas containing a tar component. A gas reforming tower, able to thermally crack the tar component in a fuel gas by increasing the temperature thereof to a process temperature, is connected to a gas supply system, which routes a biomass-source fuel gas generated by a gasification furnace, to a utilization system. Fuel gas from the gas reforming tower is routed through a fuel gas induction system to the gasification furnace for use as fuel therein during the time required for the gas reforming tower to attain the process temperature.

Abstract: The present invention provides a complementary DNA for a rice chitinase having a lytic activity against moulds and a bacteria, a complementary DNA for a rice chitinase encoding a protein comprising an amino acid sequence described in SEQ ID NO: 1 in SEQUENCE LISTING, a plasmid vector containing said complementary DNA and a transformant having said plasmid vector. The present invention enables realization of a possibility of developing a recombinant crop plant having an acquired resistance against a wide range of pathogenic microorganisms by identifying a complementary DNA encoding a novel chitinase capable of lysing cell walls of both of moulds and bacteria and introducing the sequence thereof into a plant.

Abstract: A modified enzyme having a reduced maltopentaose decomposing activity and improvements in practical usability was provided by a gene coding for .alpha.-amylase highly producing maltopentaose, the .alpha.-amylase comprising an amino acid sequence where an amino acid residue at 57- or 139-position has been substituted in the amino acid sequence of maltopentaose-forming amylase derived from Pseudomonas sp. KO-8940 (Shida, O. et al., Biosci. Biotech. Biochem. Vol. 56, 76-80 (1992)).

Abstract: An object of the present invention is to isolate complementary DNA coding for ornithine carbamyltransferase derived from a rice plant, necessary for development of a plant ornithine carbamyltransferase gene mutated to have phaseolotoxin resistance, and further to establish an expression system in microorganisms for simply evaluating the functions of the gene mutated to have resistance. This object is solved by a rice ornithine carbamyltransferase gene coding for a protein consisting of the amino acid sequence shown in SEQ ID NO:6 in the Sequence Listing, a plasmid vector containing the gene, and a transformant carrying the plasmid vector.

Abstract: A glass vessel crusher including an external cylinder 1 and an internal cylinder disposed in the external cylinder, a glass-vessel crushing space A of ring shape in section being defined by the inner wall of the external cylinder 45 and the outer wall of the internal cylinder. At least one of the external cylinder and the internal cylinder is freely rotatable and is so designed that the glass-vessel crushing space is gradually narrowed along a direction from a glass-vessel throw-in side toward a fragment discharge side, and at least one of the inner wall of the external cylinder and the outer wall of the internal cylinder is provided with a spiral projection 57 extending into the ring-shaped glass-vessel crushing space.

Abstract: A method for fixing a nose unit having a shroud panel to the front portion of a car body. Shroud upper fixing brackets are temporarily attached to the shroud panel before various parts are mounted on the shroud panel so as to assemble the nose unit on a car assembly line. The brackets serve to fix the shroud panel to the car body. In the state of temporary attachment, the brackets are welded to the car body. Then, the shroud panel is removed from the brackets. The various parts are attached to the shroud panel so as to assemble the nose unit. The shroud panel of the nose unit is fastened to the brackets, so that the nose unit is fixed to the car body.

Abstract: An apparatus for cooling a blank mold in a glass receptacle forming machine which can adjust the amount of cooling air to be supplied to a blank mold. The apparatus for cooling a blank mold includes a blank mold for forming a glass receptacle, a plurality of passages for cooling air provided in the circumferential wall of the blank mold and piercing through the circumferential wall in a vertical direction. The apparatus further includes a plenum chamber provided adjacent to said passages for temporarily storing cooling air to be supplied to the passages and having at least one inner partition wall therein to define a plurality of cavities and a damper device provided in or adjacent to the plenum chamber for adjusting the amount of cooling air to be supplied to the cavities and having at least one damper, wherein opening degree of the damper is variable so as to adjust the amount of cooling air to be supplied to the passages through the cavities.

Abstract: There is provided a process for the heat treatment of coal which comprises heating and drying low grade coal such as subbituminous coal and brown coal containing less than 80% of carbon and more than 33% of volatile matter (dry mineral matter-free basis) and having a high moisture content and a particle diameter smaller than 2 inches, with a high-temperature gas containing less than 5% of oxygen in a fluidized bed for 2-10 minutes until the coal temperature reaches 180.degree.-400.degree. C., and subsequently cooling the coal by spraying water in a fluidized bed for 2-10 minutes until the coal temperature decreases to 60.degree. C. or below at which time the coal holds the maximum moisture given by wetting. The heating process may be performed in two steps, in which case coal is heated with a high-temperature gas to 80.degree.-150.degree. C. in the first step so that the moisture of coal is reduced below the inherent moisture.

Abstract: A pillared structure of a gas-treating apparatus of a construction such that a plurality of chambers defined by partition members adjoin in a circular arrangement in the outer peripheral part of a rotary cage, each chamber being packed with an adsorbent, the cage being adapted to rotate, bringing the chambers by turns into at least an adsorption zone and then a desorption zone, characterized in that a plurality of hollow pillars for holding the partition members in place are rigidly joined at the lower ends to the upper surfaces of a plurality of rigid bottom beams radially extending from a central rotating shaft of the cage, and that holes are formed in the pillars for introducing a cooling fluid into the uprights.

Abstract: In a process for heat treatment, highly hygroscopic coal, with a low carbon content and large equilibrium moisture, is rapidly heated with hot gas at a rate of temperature rise of at least 100.degree. C./min up to a final heating temperature in the range of 300.degree.-500.degree. C., and is then rapidly cooled at a rate of temperature drop of at least 50.degree. C./min to 250.degree. C. or below. As the hot gas, an inert gas whose oxygen concentration is not higher than 4% by volume is employed. The hot gas is either caused to contain not less than 20% by volume of steam or composed solely of the steam.
