Owing to such constitution, when seen from the outside of the screen, the refraction surfaces 8 of the border surfaces 6 and 7 intersect each other and form a pattern consisting of many rhombuses, a so called diamond pattern, as is indicated in the figure. Light discharged from phosphor stripes G1, R1, B1, G2, R2...... is refracted by the refraction surfaces 8, and appears on each rhombus part, which is a component unit of the above diamond pattern, by being dispersed into the pattern indicated by the figure. Consequently, the apparent grain size of the screen becomes small.

Abstract: PURPOSE:To operate two switchovers by one driving means by providing a signal-passage which leads out the pressure of the first valve downstream chamber into a pressure-receiving chamber which actuates a diaphragm valve abutting the second valve seat. CONSTITUTION:As for the first passage 2, when a valve body 14 of the first valve seat 5 is opened by a driving means 13, the fluid led in through the first inflow passage 4 flows into the first outflow passage 7 via the first valve seat 5 and the first valve downstream chamber 6.

Next, when a valve body 14 of the first valve seat 5 is closed by the driving means 13, the flow of the first chamber passage 2 is stopped and the pressure in the first valve downstream chamber 6 is lowered. As a result, the diaphragm valve 16 is pushed to open by the fluid pressure in the second inflow passage 8, and maintained in the opened state.

Abstract: PURPOSE:To increase the resolution of a projection-type television set or the like without causing any decrease of the luminance by providing a translucent shielding body so that the amount of at least part of light transmitted by the outermost periphery of a spherical-aberration correcting body is reduced. CONSTITUTION:In the figure, a spherical-aberration correction body 14 is made of a Schmitt lens or something similar, a supporting frame 15 which is attached in front of a face plate coaxially with the face plate supports the body 14, and an annular body 22 is a translucent shielding body. The shielding body 22 is fixed between the body 14 and a flange 15' which is provided at the front end of the frame 15. The shielding body 22 decreases the amount of light, which passes through the periphery of the body 14 and becomes the cause of deteriorating the resolution of the peripheral part of a picture projected on a screen. Therefore, the resolution of the peripheral part of a picture projected on the screen is improved. In addition, since the shielding body 22 doesn't shield the whole peripheral light, the decrease of the total luminance can be reduced.
