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.

A tensioner for maintaining tension in a timing chain or belt comprises a pivotally mounted lever body biased in a direction to increase tension in the chain or belt, and having a built-in, one-way clutch permitting the lever to pivot the tension-increasing direction but blocking pivoting movement in the opposite direction.

In a hydraulic tensioner having a relief valve mechanism in which a spring-biased valve element is reciprocable in a bore, hitting sounds produced by collision of the relief valve element with a plug in the bore, and wear and breakage of the biasing spring, are prevented by providing an oil relief hole in a peripheral wall of the relief valve bore at a position where it is closed by the relief valve element when he relief valve element is moved by a rapid increase in oil pressure.

A magnetic recording medium containing a support having provided thereon a lower layer containing a nonmagnetic powder and a binder and further provided thereon at least one magnetic layer containing a ferromagnetic powder and a binder. The lower layer can contain as a binder at least a monomer unit containing from 5 to 45% by weight of a (meth)acrylate unit containing a benzene ring and from 1 to 45% by weight of a radical polymerizable monomer unit containing a nitrogen atom, with these units making a total amount of 100% by weight. It can also contain an acrylic resin having a hydrophilic polar group. The magnetic recording medium may also contain a support having provided thereon at least one magnetic layer containing a ferromagnetic powder and a binder each in the dispersed state. The magnetic layer can contain at least a monomer unit comprising from 15 to 75% by weight of an alkyl (meth)acrylate as a binder and from 1 to 45% by weight of a radical polymerizable monomer unit containing nitrogen, with these units making a total amount of 100% by weight. It can also contain an acrylic resin having a hydrophilic polar group used in combination with a resin (A) defined herein; a resin (B) defined herein; or a resin (C) defined herein.
摘要:
A solid state relay has a first external connection terminal which is conductive with one end of a main switching element, and a second external connection terminal which is conductive with another end of the main switching element, and is used with a load and a power source connected in series between the external connection terminals. A third external connection terminal is disposed in the solid state relay. The third external connection terminal is connected to the second external connection terminal via a capacitor. The load and the power source are connected in series between the first external connection terminal and the second external connection terminal, and a node of the load and the power source is connected to the third external connection terminal, thereby allowing the resistance of the load and the electrostatic capacitance of the capacitor to constitute an RC filter circuit for preventing noise leakage. Therefore, a solid state relay is obtained in which less EMI noise (noise terminal voltage) is generated, and which can be produced without especially increasing the cost and the size as compared with a relay of the conventional art.

An interline fishing rod which not only prevents stress centralization but also includes a fishing line guide and is high in strength. A rod pipe (12) includes a joining portion (12T) in the leading end portion thereof, a forwardly narrowed taper portion (12S) located just in the rear of the joining portion (12T), and a straight or forwardly narrowed and gently tapered rod pipe main body portion (12H) located in the rear of the taper portion (12S). A fishing line guide (RG2) is provided on and protected from the inside wall of the rod pipe main body portion (12H), while the inside diameter (d2) of the fishing line guide (RG2) is set larger than the inside diameters (d0) and (d4). Reinforcing layers (H1, H2) for reinforcing a main body layer are provided in such a manner that it extends from the joining portion (12T) to at least the front-most position of the fishing line guide (RG2).
摘要:
To provide a tensioner lever having a shoe made of resin is molded to prevent distortion of the shoe and increase the precision of shape and reduce the power loss caused by the abrasion of the shoe surface by friction with the chain. A tensioner lever (1) in which a shoe (3) made of resin in sliding contact with a chain is secured to a lever base (2) made of metal having a proximal end (2A) is supported rotatably about a pivotal axis so that an extreme end (2B) can be pivoted, wherein a portion of the shoe (3) having a large wall-thickness is formed with cored-out portions (3F, 3H) whereby when the shoe is molded, the resin for material thereof uniformly flows within a mold, a curing speed of the whole shoe (3) is made uniform, and distortion when molding is prevented to enhance the shape precision of the shoe (3) and the mounting precision to the lever base (2).
