In one embodiment, an aqueous dispersion liquid contains at least one particles selected from tungsten oxide particles and tungsten oxide composite particles. A mean primary particle diameter (D50) of the particles is in the range of 1 nm to 400 nm. In the aqueous dispersion liquid, concentration of the particles is in the range of 0.1 mass % to 40 mass %, and pH is in the range of 1.5 to 6.5. The aqueous dispersion liquid excels in dispersibility of particles and capable of maintaining good liquidity for a long period.

An internal combustion engine with a turbocharger that can favorably prevent an exhaust gas purifying catalyst from being clogged with a manganese oxide contained in an exhaust gas is provided. The internal combustion engine includes a turbocharger that includes a turbine disposed in an exhaust passage, the turbine being operative by exhaust energy of the internal combustion engine; an upstream catalyst, disposed in the exhaust passage at a downstream side of the turbine, for purifying an exhaust gas; an exhaust bypass passage for bypassing the turbine; and a waste gate valve for opening or closing the exhaust bypass passage. The waste gate valve is controlled to be in an open state during performance of a fuel cut of the internal combustion engine.

A wire guide housing (1) which contains a wire guide (6) for supporting a running wire electrode (W) and in which a wire running passage (32, 23b, 41, 26, 63, 66a) through which the wire electrode passes is formed. The wire guide housing includes: a cleaning liquid supply opening (43), for introducing a cleaning liquid (C) into the wire guide housing; a cleaning liquid discharge opening (44), for discharging the cleaning liquid from the wire guide housing; a first flow passage (46), for connecting the cleaning liquid supply opening to the wire running passage; and a second flow passage (48), for connecting the wire running passage to the cleaning liquid discharge opening. The cleaning liquid flows into the wire running passage at a side more upstream than the wire guide.

摘要:
An object of the present invention is to provide a novel antischistosomal agent, and more specifically, to provide a novel drug capable of inhibiting a growth of schistosomes in vivo to prevent development of liver dysfunction due to eggs of the schistosomes in the case of infection with the schistosomes. The novel antischistosomal agent includes as an active ingredient a peroxide derivative. Specifically, the novel antischistosomal agent includes as an active ingredient a peroxide derivative represented by the general formula (I): where C represents an alicyclic hydrocarbon ring group which may be substituted, and n represents an integer of 1 to 6.
