摘要:
Provided is a chlorine dioxide-generating product comprising an inorganic porous carrier carrying a chlorite and an alkali agent. In the product, the alkali agent is carried in an amount of more than 0.7 molar equivalent and not more than 2 molar equivalents relative to the amount of the chlorite carried, and the product has a water content of 10% by weight or less. The chlorine dioxide-generating product can stably generate chlorine dioxide gas in an amount that sufficiently achieves deodorization, sterilization, virus removal, mold prevention, antisepsis, or the like of spatial environments, foods, or others but exerts no harmful effect on humans, over a long period of time.

A substrate holding apparatus can meet the request for a smaller-sized compact apparatus while ensuring a sufficient immersion depth of a substrate in a processing liquid. The substrate holding apparatus includes: a substrate holder for supporting a substrate (W) by bringing a peripheral portion of a surface of the substrate (W) into contact with a first sealing member; and a substrate pressing section for lowering relative to the substrate holder so as to press the substrate (W) held by the substrate holder downward, thereby bringing a first sealing member into pressure contact with the substrate (W). The substrate pressing section is provided with a second ring-shaped sealing member which makes pressure contact with an upper surface of a ring-shaped holding section of the substrate holder, thereby sealing the peripheral region of the substrate pressing section.

A transparent multilayer stretched product is produced through a process including: providing a resin laminate including at least on layer of polyglycolic acid resin, heat-forming and cooling the resin laminate, reheating the resin laminate until the polyglycolic acid resin is crystallized to be opaque and then stretching the reheated resin laminate. The thus-obtained multilayer stretched product is excellent in gas-barrier property in addition to the transparency and is suitable as a packaging material or container.

There are provided a bottle which has a laminate structure including a glycolic acid polymer layer showing good gas-barrier property in addition to a principal resin layer and is yet provided with excellent recyclability, and also an efficient method of recycling the bottle. More specifically, a bottle having a laminate structure including at least one layer of glycolic acid polymer in addition to a principal resin layer, is obtained. After breaking the bottle, the broken pieces are washed with alkaline water, water or acidic water to remove the glycolic acid polymer layer, thereby recovering the principal resin.

A reciprocating piston type compressor for compressing refrigerant gas includes a plurality of pistons slidably provided within cylinder bores for reciprocation. A pair of housings are mounted to the either ends of the cylinder block with valve plates therebetween. The housings include at least a refrigerant gas suction chamber which is fluidly connected to the cylinder bores. An oil sump is provided for containing lubricating oil. An oil pump is provided for distributing the lubricating oil to the compressor elements. The oil pump includes oil suction which is fluidly connected to the oil sump through a oil suction passage. The pressure in the refrigerant gas suction chamber is introduced into the oil suction chamber to direct the lubricating oil into the oil suction chamber from the oil sump during the initial stage of the starting of the compressor.

A method for producing a polyglycolic acid fiber, including: obtaining undrawn yarns by melt spinning a polyglycolic acid resin; keeping the undrawn yarns under a temperature condition of 1 to 20° C.; obtaining drawn yarns by drawing the kept undrawn yarns; and, if necessary obtaining a staple fiber by cutting the drawn yarns.

A method for dismantling a furnace having a multilayered refractory structure including: a furnace shell; a containing layer that is formed of a containing refractory that contains asbestos, and covers the inner side of the furnace shell; and a multilayered non-containing layer that is formed of a non-containing refractory that contains no asbestos, and covers the inner side of the containing layer, the method includes: a primary dismantling process; and a secondary dismantling process conducted after the primary dismantling process. In the primary dismantling process, the non-containing layer is dismantled from a furnace-core side thereof but the containing layer and at least one layer of the layers forming the non-containing layer, which is in contact with the containing layer, are left as a remnant. In the secondary dismantling process, the remnant is dismantled while asbestos measures are implemented.
摘要:
A laminate includes: a crystallized polyglycolic acid-based resin layer containing 100 parts by mass of a crystallized polyglycolic acid-based resin having a spherulite diameter of 1 to 30 μm and 0.0075 to 0.20 parts by mass of at least one nucleating agent selected from the group consisting of boron nitride particles, molybdenum sulfide particles, and tungsten sulfide particles; and a thermoplastic resin layer adjacent to the crystallized polyglycolic acid-based resin layer.
