    摘要: To provide a variable valve driving device which can accurately control the lift amount of valves and can be manufactured at a low cost. The device has: valves (10) serving as intake valves or exhaust valves of an engine; springs (11) for biasing the valves (10) in the valve closing direction; a cam (12) for pressing the valves (10) in the valve opening direction against a biasing force of the springs; a piston (19) joined to the valves (10); a control chamber (21) configured by a piston insertion hole (20) into which the piston (19) is inserted; and a control mechanism (24) for changing the valve closing timing of the valves (10) by controlling the introduction and discharge of a working fluid into and from the control chamber (21).

    摘要: A diaphragm for loudspeakers comprises chitin as a natural high polymeric material having a large value of Young's modulus and kraft pulp having large mechanical internal loss. Therefore, the deformation and the partial vibrations of the diaphragm during diaphragm operation do not come out due to the use of the chitin, because the flexural rigidity of the diaphragm is considerably large. Mechanical internal loss is also large owing to the use of the kraft pulp. As a result, it is possible to obtain a loudspeaker which has little fluctuation in frequency response, and which provides a superior sound pressure-frequency response, a superior distortion factor and a superior phase response.

    摘要: In a vane pump, a pump housing contains a cam ring having an internal cam surface, in which a rotor carrying eight vanes is rotatable by a drive shaft. A pair of side plates positioned in the receiving bore in contact engagement with the opposite end surface of the cam ring, the internal cam surface and the rotor define a pump chamber. Each of the side plates is formed at its inside surface contacting the cam ring with a pair of intake ports, a pair of exhaust ports and a vane back pressure groove. This groove is always filled with pressurized fluid supplied from the exhaust ports such that the pressurized fluid is directed into vane support slits formed in the rotor. The angular width between the start point of each of the intake ports and the start point of one of the exhaust ports is chosen to an angle of 90 degrees which is twice the pitch of the vanes, and the angular width of each of the exhaust ports is chosen to be not larger than or angular width which outer end surfaces of two successive vanes make, whereby the volume of pressurized fluid which leaks from the vane back pressure groove towards the intake ports through a clearance between the rotor and each side plate can be maintained constant.
