Title: Controller of fluid joint clutch
Inventor: NAKAMURA SHOJI
IPC: F16H61/14
Filed: 1994-04-19
Abstract: PURPOSE:To reduce changeover shock at the time of changeover between partial cylinder operation and all cylinder operation by reducing feed oil pressure to a clutch once into first oil pressure by means of a first pressure reducing means, reducing pressure further at a first slope by means of a second pressure reducing means, when the operation of an engine is changed over from all cylinder operation to partial cylinder operation. CONSTITUTION:When the operation of an engine 1 is changed over from all cylinder operation to partial cylinder operation, feed oil pressure to a damper clutch 28 is reduced into first oil pressure once by means of a first pressure reducing means, and is further reduced at a first slope by means of a second pressure reducing means. As a result, the damper clutch 28 falls rapidly into the state of non-direct connection or the state of slipping with very small torque, and torque change following cylinder changeover is absorbed. Afterwards, feed oil pressure to the damper clutch 28 is increased at a second slope by means of a pressure decreasing means, and transfer to a partial cylinder operation time operation state in which, for example, feedback control is made so as to slip at a predetermined slip amount, is carried out.

Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To precisely control the additive concn. in an electrolyte feed liquid by subjecting an electrolyte to an active carbon treatment and adding a prescribed amt. of an additive into the electrolytic feed water after the treatment. SOLUTION: Copper is electrodeposited on a cathode drum rotating in an electrolytic cell 1, thereby copper foils for printed circuit boards are produced. The electrolyte in the electrolytic cell 1 is accepted through a tail liquid vessel 2 and a dissolving vessel 3 into a make-up liquid storage tank 4. The electrolyte in this make-up liquid storage tank 4 is fed to an active carbon column 5 where the old additive included in the electrolyte is adsorbed away and the electrolyte is sent to the make-up liquid storage tank 4'. The prescribed amt. of the additive is added from an additive storage tank 6 to the electrolyte in the make-up liquid storage tank 4'. The amt. of the additive is adjusted by the flow rate of the electrolyte. After the old additive in the electrolyte is removed, the prescribed amt. of the additive is freshly added thereto and, therefor, the precise control of the additive concn. is made possible. Then, the properties of the copper foils are easily controlled. The selective production of the copper foils varying in the level of a hot elongation rate is made possible by adjusting the amt. of the additive to be added.
