Abstract:
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.
Abstract:
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.

Abstract:
The present invention is to provide a nonaqueous electrolytic solution prepared by dissolving an electrolyte salt in a nonaqueous solvent, wherein the nonaqueous solvent includes 0.01 to 40% by volume of an ester having two alkyl groups at the α-position carbon of the carbonyl group and being represented by the following general formula (I), and an energy storage device. (in the above formula, R1 is an alkyl group, an alkenyl group or an alkynyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom, R2 and R3 are an alkyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom, and R2 and R3 may be linked to each other to form a ring. However, when R2 and R3 do not form a ring, R3 is an alkyl group in which at least one of the hydrogen atoms may be substituted with a halogen atom.).
Abstract:
The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a broad temperature range, such as low-temperature cycle properties and low-temperature discharge properties after high-temperature storage, and provides an energy storage device using the nonaqueous electrolytic solution. The invention includes (1) a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, which comprises from 0.001 to 10% by mass of a compound represented by the following general formula (I), and (2) an energy storage device comprising a positive electrode, a negative electrode, and a nonaqueous electrolytic solution of an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolytic solution is the nonaqueous electrolytic solution of (1). (In the formula, Y represents a group —C(═O)— or a group —S(═O)2—; R3 and R4 each independently represent an aryl group having from 6 to 10 carbon atoms in which at least one hydrogen atom is substituted with a halogen atom, or R3 and R4 bonding to each other represent a cycloalkanediyl group or a benzenediyl group, having from 5 to 12 carbon atoms. R represents —C(R1)(R2)— or -L-; R1 and R2 each independently represent a hydrogen atom, a halogen atom, or an alkyl group having from 1 to 4 carbon atoms; and L represents a divalent linking group having from 1 to 6 carbon atoms and optionally substituted with a halogen atom).
Abstract:
In an image forming apparatus, photosensitive bodies are mounted in a first frame. Developing units are detachably mounted in the first frame. A second frame is movable relative to the first frame. Each developing unit is movable relative to the first frame between a separate position, at which a developing roller is separate from a photosensitive body, and a contact position, at which the developing roller is in contact with the photosensitive body. The second frame moves relative to the first frame, thereby moving the developing units relative to the first frame between the separate positions and the contact positions. The second frame positions each developing unit relative to the first frame in a direction to move the developing roller toward the corresponding photosensitive body when the developing unit is in the contact position.
