摘要:
In a hydraulic chain tensioner having a housing, a hollow plunger slidable in a plunger-accommodating hole in the housing, and a hollow sleeve extending into the plunger from a bottom of the plunger-accommodating hole, and a check valve mounted at the opposite end of the sleeve, a passage is provided on the outer surface of the sleeve to accelerate the balance of pressure between a first high pressure chamber between the check valve and the protruding end of the plunger and a second high pressure chamber between the inner end of the plunger and the bottom of the plunger-accommodating hole. In an alternative embodiment, balance is accelerated by communication between the second high pressure chamber and an oil reservoir inside the sleeve on the upstream side of the check valve.

A check valve unit in a hydraulic tensioner comprises a check ball, a steel ball guide having an inner wall allowing a limited range of longitudinal movement of the ball but restricting its lateral movement, a steel retainer attached to the high pressure oil chamber side of the ball guide, and a steel ball seat attached to the oil supply side of the ball guide. Bulged portions formed on an outer surface of the ball guide are press-fit into the plunger-accommodating hole of the tensioner.

In a tensioner lever assembly for a chain transmission, an auxiliary lever, arranged to pivot relative to a main tensioner lever, engages a free span of the chain approaching the main lever from a driving sprocket. The auxiliary lever can be pivoted coaxially with the main lever, and can extend either toward the center of the main lever, or toward the driving sprocket. Alternatively, the auxiliary lever can be pivoted on the main lever at a location remote from the pivot axis of the main lever, and engaged with a free span of the chain moving away from the main tensioner lever and approaching a driven sprocket.

The present invention is intended to provide halogen-free propylene-containing flame retardant resin formulations having high levels of impact resistance. More particularly, the present invention is intended to provide a halogen-free propylene-containing flame retardant resin formulation which is excellent in mechanical properties such as tensile strength, flexibility, low temperature flexural properties, chemical resistance, heat resistance and abrasion resistance, and an electrical wire having insulation coating formed of the same halogen-free propylene-containing flame retardant resin formulation and having high levels of impact resistance.The afore-mentioned object can be achieved by a polypropylene-containing flame retardant resin formulation having viscoelastic property value tan δ of greater than or equal to 0.1 at 25° C., for a frequency of 1 to 30 Hz, and type D durometer hardness of 68 to 74, comprising a base resin composition comprising 65 to 90 parts by weight of polypropylene, and 10 to 35 parts by weight of at least one component selected from the group consisting of polyethylene-based resins, olefin-based thermoplastic elastomers, and styrene-based thermoplastic elastomers, based on the total parts by weight of the base resin composition, and 60 to 100 parts by weight of an inorganic flame retardant additive, based on the total parts by weight of the base resin composition.
摘要:
The present invention provides a fuel gasification furnace including a gasification chamber (1) for fluidizing a high-temperature fluidizing medium therein to form a gasification chamber fluidized bed having an interface, and for gasifying a fuel in the gasification chamber fluidized bed, a char combustion chamber (2) for fluidizing a high-temperature fluidizing medium therein to form a char combustion chamber fluidized bed having an interface, and for combusting char generated by gasification in the gasification chamber (1) in the char combustion chamber fluidized bed to heat the fluidizing medium, and a first energy recovery device (109) for using gases generated by the gasification chamber (1) as a fuel. The gasification chamber (1) and the char combustion chamber (2) are integrated with each other. The gasification chamber (1) and the char combustion chamber (2) are divided from each other by a first partition wall (15) for preventing gases from flowing therebetween, and which extends vertically upward from the interfaces of the respective fluidized beds. The first partition wall (15) has a first opening (25) provided in a lower portion thereof, and the first opening (25) serves as a communication between the gasification chamber (1) and the char combustion chamber (2), for allowing the fluidizing medium heated in the char combustion chamber (2) to move from the char combustion chamber (2) via the first opening (25) into the gasification chamber (1).

摘要:
In a lever for a transmission device comprising a lever body including a shoe and a support on the back of the shoe, the lever body is integrally molded of a synthetic resin, and a metal reinforcing plate is held on the support so that it extends along the longitudinal direction of the lever body. The lever body and the metal reinforcing plate are integrally formed by insert molding using the metal reinforcing plate as an insert fitting.
摘要:
An ion implantation apparatus includes an ion irradiation unit. The ion irradiation unit irradiates a plurality of areas of a target substrate with ion beams each of which reaches the substrate at corresponding one incident angle. An incident angle measuring instrument measures the incident angle of each of the ion beams. A controller is provided with information from the incident angle measuring instrument and controls the ion irradiation unit in accordance with the information so that a difference among incident angles is set to within ±0.1°.
