摘要： A hydraulic control apparatus for switching an operation of a hydraulically operated mechanical apparatus, by selectively operating two frictional engagement elements of a first, a second, a third, and a fifth frictional engagement elements, the hydraulic control apparatus including a first control valve which, in association with an event that respective hydraulic pressures to operate the first and second frictional engagement elements are both produced, drains one of the third and fifth frictional engagement elements and outputs a control hydraulic pressure; and a second control valve which, when at least two hydraulic pressures of (a) the control hydraulic pressure and (b) respective hydraulic pressures to operate the third and fifth frictional engagement elements are supplied to the second control valve, drains the other of the third and fifth frictional engagement elements.

摘要： A rear projection screen of the present invention includes lens sheets or optical sheets having an optical function of condensing or diffusing light. The lens sheets or optical sheets have, as a whole, two or more diffusing layers (diffusing parts) separately provided in the light-transmitting direction. It is preferable that one of the two or more diffusing layers be provided on the light-entering-side surface of the outermost lens sheet or optical sheet on the light source side and that another one of the diffusing layers be provided on the light-emerging-side surface of the outermost lens sheet or optical sheet on the observation side. Any two of the two or more diffusing layers are such that the light-source-side diffusing layer has a diffusing power lower than that of the observation-side diffusing layer. Further, it is preferable that the types (refractive indexes or average particle diameters) of diffusers to be respectively incorporated into any two of the two or more diffusing layers be different from each other.
