摘要： A chain tensioner for use with a chain of a vehicle engine, includes a housing and a plunger slidably mounted in a cylinder chamber formed in the housing. The plunger is biased outwardly by a return spring mounted in a pressure chamber defined in the cylinder chamber by the plunger. A check valve is provided in the cylinder chamber to prevent backflow of hydraulic oil in the pressure chamber. A relief valve, provided in the plunger, opens above a relief pressure, thereby discharging hydraulic oil in the pressure chamber. An oil leakage clearance is defined between the plunger and the inner wall of the cylinder chamber. The relief pressure and the oil leakage clearance dimension are determined such that the tension in the chain is kept at such a level that vibrations of the chain are minimum at any temperature of hydraulic oil and at any engine revolution speed.

摘要： A water purifying unit generates pure water by eliminating impurity ions from dielectric fluid. A corrosion-protection-ion generating unit generates corrosion protection ions, substitutes predetermined cations for impurity cations contained in the dielectric fluid, and substitutes the corrosion protection ions for impurity anions contained in the dielectric fluid. A switching unit switches a supply of the dielectric fluid between the water purifying unit and the corrosion-protection-ion generating unit. A switching control unit controls the switching unit based on a conductivity of the dielectric fluid measured by a conductivity measuring unit.

摘要： A chain tensioner includes a housing having a cylinder chamber. A plunger is slidably mounted in the cylinder chamber. A spring is mounted in the cylinder chamber to bias the plunger outwardly of the cylinder chamber. The plunger has a radially extending locking pin at its lower portion near its front end. The housing is formed with a pin hole extending substantially perpendicular to an axis of the cylinder chamber near the front end of the housing and under the cylinder chamber. The chain tensioner further includes a support pin inserted in the pin hole, and a locking lever supported on the support pin so as to be pivotable about the support pin. The locking lever can engage the locking pin when the plunger is sufficiently pushed into the cylinder chamber, thereby keeping the plunger pushed in the cylinder chamber.

摘要： A chain tensioner includes a housing defining a cylinder chamber having a closed end. A cylindrical plunger having a closed front end is slidably received in the cylinder chamber. A nut member and a return spring are mounted in the cylinder chamber. The return spring biases the plunger outwardly of the housing to press its closed end against a pivotally supported chain guide. The nut member has a serration-shaped internal thread formed on the inner periphery thereof which is in threaded engagement with a serration-shaped external thread formed on the outer periphery of the screw rod. The screw rod is biased toward the closed end of the plunger by a rod spring. A damper is mounted between the front end of the screw rod and the closed front end of the plunger for damping, in cooperation with the return spring, a pushing force applied to the plunger, and for allowing the screw rod and the plunger to move relative to each other in a direction in which the distance between respective remote ends thereof decreases by an amount not less than an axial play present between the internal and external threads.

摘要： A stepped set groove having shallow and deep portions is formed in the inner periphery of a cylinder chamber formed in a housing of a chain tensioner near its open end. A radially and elastically deformable set ring having circumferentially separated ends is received in the set groove in a radially compressed state. The set ring has at the respective ends thereof a pair of grip portions which are received in a cutout formed in housing at its front end. By engaging the set ring in an engaging groove formed in the outer periphery of the plunger near its front end and the shallow portion, it is possible to keep the plunger pushed into the cylinder chamber. In this state, the chain tensioner is mounted in position. One of the grip portions is brought into abutment with one of the circumferentially opposed end walls of the cutout to prevent the plunger from rotating about its axis in such a direction that the axial gap between an internal thread of the plunger and an external thread of a screw rod inserted in the plunger disappears. Thus, it is possible to keep the axial gap larger than the axial distance by which the plunger has to be moved to move the set ring from the shallow portion into the deep portion. This makes it possible to disengage the set ring from the engaging groove by pushing the plunger into the cylinder chamber.

摘要： A coding and decoding apparatus is constructed so that the coding side transmits coded data together with identifying information for identifying the device of decoding the coded data, and the decoding side is capable of storing a number of decoding schemes so as to perform decoding based on one of the previously stored schemes. The apparatus further has devices for storing the received tools and tool-correspondent information which numerically represents the capacities of the tools so that it can make a comparison between the decoding capacity and the processing capacities of the tools to determine the possibility of the operations of the received tools. Further, a set of the tools are hierarchized so that the coded data produced by the n-ranked tool can be decoded by the (n+1)-ranked tool. Alternatively, the tools are defined in a hierarchical manner so that the decoding tools installed in the decoding apparatus will be able to assure the minimum quality and the requested decoding process can be performed by the received decoding tool. Further, the identification code of the decoding scheme used can be transmitted as required so that the decoding scheme can be expanded by transmitting the differential information from the basic decoding scheme.
