Abstract: The slurry for carrying zeolite of the present invention is slurry for attaching zeolite to a carrier and comprises zeolite and an organic emulsion binder dispersed in water. This slurry for carrying zeolite has viscosity not excessively high in spite of a large content of zeolite and binder and has a pH at which the zeolite and binder are stable. The slurry therefore can be stored for a long time in a stable manner.

Abstract: An oil application device having an oil application amount control layer bonded to an oil retaining member for retaining application-use silicone oil using the mixture of adhesive and mixture-use silicone oil. The ratio (VKS)/(VTS) of a viscosity (VKS) of the mixture-use silicone oil at 25° C. to a viscosity (VTS) of the application-use silicone oil at 25° C. ranges from 50/1 to 1/10. By using the oil application device, releasing oil can be applied to a thermal fixing roller uniformly. The oil application amount control layer does not peel off or is not displaced during operation, and no oil exudes during nonuse.

Abstract: A chemical filter is provided with an adsorbent filter medium for removing gaseous impurities and agglutinating organic substances in the air. The adsorbent filter medium is of a corrugated honeycomb structure comprising fiber material and is a fiber base paper having an interfiber void ratio of 80 to 95% upon which a gas adsorbent or a gas reactant has been deposited. As a result, using fiber which contains substantially no boric oxide as the absorbent fiber medium enables contaminants generated from the chemical filter itself to be removed, and therefore improves the yield of semiconductors and precision electronic components manufactured. Moreover, the amount of active carbon deposited is markedly high, and thus, if impregnated with a reactant, the amount of reactant deposited is able to be increased, leading to superior removal performance with respect to gaseous contaminants as well as reduced pressure loss and longer life of the filter.
