Abstract: PURPOSE: To facilitate smooth fluid supply into the mold by rotatably fitting a supply cylinder fixed thereto a plural number of conduits into a distributing cylinder fixed to a mold plate and slidably passing said conduits through a movable  plate.  
     CONSTITUTION: A fluid enters from the top end of a conduit 24, passes through the holes 22 1 , 22 2  in a feed cylinder 18 and the ring grooves 21 1 , 21 2  and then guided to the holes 20 1 , 20 2  in a distributing cylinder 16 and thence supplied into the mold through suitable piping. For return from the mold, the fluid passes said route contrariwise and is returned from another conduit 24. For replacement of the sealant 23, first the tie bar 13 and movable plate 10 are removed and then the distributing cylinder 16 is detached from the mold plate 15, whereby the feed cylinder 18, distributing cylinder 16 and conduits 24 can be removed all together through a hole 11 in the movable plate 10, allowing easy replacement of the sealent. Thus, since both distributing cylinder and feed cylinder are small in size and light in weight, parts assemblage can be accomplished with ease.

Abstract: PURPOSE:To obtain an uniform and vivid picture of high resolution by successively changing the pitch of picture elements from the center toward the periphery in the solid-state image pickup device which obtains an electric signal corresponding to an optical image. CONSTITUTION:On the side of the photosensitive face of a CCD 13, each picture element has the size gradually changed so that it is 2% smaller than a standard in the center part and is 5.1mum long and 4.9mum wide there and it is 2% larger than the standard in the peripheral part and is 5.3mum long and 5.1m wide there. Therefore, the whole of picture elements takes a form that is narrow in the middle. Color filters, micro lenses, of the like added to this CCD 13 are formed like inverted barrels in accordance with respective picture elements in the same manner. Since the optical image obtained by an image pickup lens for HDTV has a tendency to be distorted to a form that is narrow in the middle, the photosensitive face of the CCD 13 is formed like the inverted barrel to cancel this distortion of the optical image obtained by the image pickup lens.
