摘要： A device for reducing friction while maintaining characteristics identical to the pressure characteristics of a common oil pump based on provision of a plurality of discharge sources and a newly devised method of switching oil passages. The device is configured from a first discharge passage from a first rotor assembly to an engine, a first return passage that returns to an intake side of the first rotor assembly, a second discharge passage from a second rotor assembly to the engine, a second return passage that returns to an intake side of the second rotor assembly, and a pressure control valve whose valve main body is provided between a discharge port from the second rotor assembly and the first discharge passage. The first discharge passage and the second discharge passage are coupled, and a flow passage control is executed in each of: a low revolution range in a state in which only the first discharge passage and the second discharge passage are open; an intermediate revolution range in a state in which the first discharge passage and second discharge passage are open and the first return passage is closed while the second return passage is open; and a high revolution range in a state in which the second discharge passage is closed while the first discharge passage is open and the first return passage and second return passage are open.

摘要： An estimation system for estimating an injection-molding related cost comprises an input unit, storage, a data processing unit, and an output unit. The storage stores a mold estimation function for each of cost items of a mold used to produce a molded product, and a mold estimation reference value table for recording mold estimation reference values in association with prescribed conditions. The data processing unit acquires a fabrication condition of the molded product through the input unit, reads the mold estimation function and one of the mold estimation reference values from the storage corresponding to the fabrication condition, and estimates a cost of the mold based on the mold estimation function and the selected mold estimation reference value. The output unit outputs a mold cost estimation result made by the data processing unit.

摘要： A throttle valve device for use in an internal combustion engine comprises a valve shaft extending across an air induction passage of the engine. A valve plate is fixed to the valve shaft to rotate therewith in the air induction passage. An electric actuator is connected to one end of the valve shaft to rotate the valve shaft with the aid of electric power. A biasing cam structure is incorporated with the valve shaft to bias the valve place toward a predetermined intermediate open position. The biasing cam structure comprises a cam plate which is secured to the other end of the valve shaft to rotate therewith and has a generally V-shaped cam edge; a loading lever which has a base end pivotally connected to a fixed portion; a follower member which is connected to a leading end of the loading lever and slidably engaged with the V-shaped cam edge; and a biasing member which biases the loading lever in a direction to press the follower member against the V-shaped cam edge.
