Abstract: An object of the invention is to provide a positive clutch that has a high rigidity and simple structure, and offers potential to allow easy adjustment of torque limit load, suppress friction loss and noise generation, realize a size reduction, and extend the service life. This positive clutch is configured to prohibit relative rotation of an outer and inner races by circumferentially holding each of a plurality of rollers between an outer race slope portion and an inner race slope portion. The clutch includes a torque limiter mechanism, which includes a piston member having a flat portion that forms the outer or inner race slope portion, and a resilient member that applies a constant load on the piston member. The piston member is slidably accommodated in a piston member accommodating hole formed in the outer race or the inner race.

Abstract: An object of the present invention is to provide a tensioner with a simple structure that effectively maintains the oil pressure inside an oil pressure chamber at a correct level, while also making the machining and assembling processes less demanding. The tensioner includes a relief mechanism, which includes an orifice member that has an oil passage designed to form an orifice structure. The orifice member has a flat circular end wall part and a circumferential wall part that extends rearwards from the peripheral edge of the end wall part. The circumferential wall part includes a bulged portion that extends rearwards and is curved radially outwards. The bulged portion is designed such that the diameter of the circumscribed circle of the orifice member is greater than the inside diameter of the plunger as viewed in plan from an axial direction before the orifice member is press-fit into the plunger.

Abstract: Provided are a charging and discharging device, a charging and discharging control method, and a computer readable medium storing a computer program capable of causing a higher-level device to implement appropriate charging and discharging control. The charging and discharging device has a connector for connecting to an in-vehicle storage battery provided in a vehicle, one or more processors that processes to control charging and discharging in the in-vehicle storage battery, a memory, a communication unit that communicates with an in-vehicle control device of the vehicle, and a higher-level communication unit that communicates with a higher-level control device. The processor stores, in advance, stores values for performing charging and discharging, determines the values based on data transmitted to and from the in-vehicle control device for controlling charging and discharging; and notifies the higher-level control device of either the determined values or the values read from the memory.

Abstract: To provide a simple-structured cam clutch that does not require precise control and is operable with a smaller drive force and less prone to damage on cam surfaces or inner and outer raceways. The cam clutch includes a plurality of cams circumferentially arranged between an inner race and an outer race and supported by a cage member, and a selector capable of changing an orientation of the cams. The selector includes a driven part allowing a rotation angle thereof to be controlled relative to the inner race or outer race to which the cage member is fixedly attached, and a selector body circumferentially displaceable relative to the driven part in a resilient manner by a spring-loaded mechanism. The selector body includes a cam orientation control protrusion capable of changing the orientation of the cams by making contact with the cams.

Abstract: To provide a simple-structured cam clutch that does not require precise control, uses a smaller drive force for forcibly changing cam postures, and provides improved clutch operation stability and high responsiveness. The cam clutch includes a plurality of cams circumferentially arranged between an inner race and an outer race and supported by a cage member, and a selector allowing a rotation angle thereof to be controlled relatively to the inner race or the outer race to which the cage member is fixed. The selector has a cam posture control surface in contact with cam surfaces of the cams and capable of causing the cams to change posture thereof. The cam posture control surface includes a cam release portion radially protruded toward the cams more than a cam actuator portion and causing the cams to change posture thereof to a non-operating posture.
