摘要:
An improved and simplified outboard motor construction wherein the cooling and exhaust systems for the engine are formed with a minimum number of components and sealing joints and incorporating a non-metallic cam shaft for reduced cost and weight without sacrifice of durability. The exhaust system includes an elongated expansion chamber formed in the drive shaft housing. In addition, the drive shaft housing has a cylindrical section that is journaled within a swivel bracket for its steering movement. The volume between the external portion of the drive shaft housing and the internal portion of the swivel bracket forms a second expansion chamber that is employed for the low speed above the water exhaust gas discharge. The flow of cooling the water to and from the engine is controlled so that the exhaust gas interchange area between the power head and the drive shaft housing will be well cooled, as will the oil reservoir for the engine and the oil returned to it.

Several embodiments of venting arrangements for the lubricant pump of a two-cycle, crankcase compression internal combustion engine for an outboard motor and having a positive lubricating system. In each embodiment, the lubricant pump is provided with a vent passage that extends from an upper portion of a chamber of the pump for venting air from it. In each embodiment, an arrangement is provided for permitting air flow from the fluid pump without returning to the fluid pump. In some embodiments, this means comprises a check valve and in another embodiment, it comprises a restricted orifice.

The present invention is to provide a nonaqueous electrolytic solution capable of enhancing electrochemical characteristics in a broad temperature range, an energy storage device using the nonaqueous electrolytic solution, and a specific trifluoromethylbenzene compound. There are provided a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which comprises at least one halogenoalkylbenzene compound represented by the following general formula (I), an energy storage device using the nonaqueous electrolytic solution, and a specific trifluoromethylbenzene compound. (In the formula, Y1 represents an alkoxycarbonyl group having from 2 to 8 carbon atoms, an alkenyloxycarbonyl group having from 3 to 9 carbon atoms, an alkynyloxycarbonyl group having from 4 to 9 carbon atoms, an aryloxycarbonyl group having from 7 to 12 carbon atoms, an alkanesulfonyl group having from 1 to 6 carbon atoms, or an arylsulfonyl group having from 6 to 12 carbon atoms; RX represents a halogenoalkyl group having from 1 to 4 carbon atoms; n indicates an integer of from 1 to 5. However, when Y1 is an alkoxycarbonyl group having from 2 to 12 carbon atoms or an aryloxycarbonyl group having from 6 to 12 carbon atoms, the number of carbon atom of RX is 1. In the substituent represented by Y1, at least one hydrogen atom may be substituted with a halogen atom.)
摘要:
A photosensitive member unit includes: a first image forming unit including a first photosensitive member rotatable on a first axis line; and a second image forming unit including a second photosensitive member rotatable on a second axis line parallel with the first axis line and disposed in parallel with the first image forming unit at a first side in an orthogonal direction perpendicular to the first and second axis lines. The first image forming unit includes a charger and a cartridge containing portion. The charger includes: a charging member; a cleaning member for cleaning the charging member; and an operating member for operating the cleaning member. The operating member is inoperable when the developing cartridge is installed in the cartridge containing portion, and is exposed to be operable in the cartridge containing portion when the developing cartridge is removed from the cartridge containing portion.

The non-aqueous electrolytic solution includes a non-aqueous solvent and an electrolyte salt dissolved in the non-aqueous solvent, wherein the non-aqueous electrolytic solution further comprises one compound represented by general formula (I): wherein R1 represents alkyl having 1 to 6 carbon atoms, cycloalkyl having 3 to 6 carbon atoms, alkenyl having 2 to 6 carbon atoms, alkynyl having 3 to 6 carbon atoms, or aryl having 6 to 12 carbon atoms; X represents a divalent linking group that has 1 to 6 carbon atoms and is optionally substituted by a halogen atom; and Y1 represents a specific substituent, for example, alkylcarbonyl.
摘要:
A shaft-receiving device connects a rotating member and a frame. The rotating member has a rotational axis extending in a first direction and at least one end in the first direction. The frame extends in a second direction perpendicular to the first direction and is formed with a through-hole having an inner peripheral surface. The shaft-receiving device includes a shaft-receiving portion and a pressing member. The one end is inserted into the shaft-receiving portion in the first direction. The shaft-receiving portion is inserted into the through-hole in the first direction and opposes the inner peripheral surface in the second direction. The pressing member opposes the inner peripheral surface in the second direction to press the rotating member toward the inner peripheral surface.
摘要:
A composition for stabilizing chlorine dioxide maintains a chlorine dioxide concentration nearly constant in the agent containing chlorine dioxide dissolved therein even when chlorine dioxide is continuously released as gas from agent, and includes a chlorite and a pH adjuster. The pH adjuster is an acid or a salt thereof having a buffering property whose pH is 2.5 to 6.8 as a 5% aqueous solution at 25° C.
