Abstract: In order to overcome a difficulty in which, when a moving image played back by an operated-side computer is displayed on an operating-side computer through a network, a smooth moving image cannot be displayed because of being adversely influenced by the variation of a transfer data amount or a network bandwidth, a moving image displaying method and system are arranged to capture moving image playback event information being remotely operated and convey the information about the playback of the moving image on the operated-side computer to the operating-side computer. The operating-side computer provides a function of obtaining and receiving the moving image data played back on the event information, playing back the display image from the obtained moving image data, and overlapping the display image with the remote operation view.

Abstract: A moving image displaying method to be executed in a network computer system having an operating-side computer and an operated-side computer coupled through a network, the operating-side computer coupling with the operated-side computer for performing input operation to the operated-side computer, and an operation result view appearing on the operated-side computer being displayed on a display unit of the operating-side computer, including the steps of: capturing, by the operated-side computer, event information inputted by the operating-side computer, the event information being information about a playback operation of a moving image; transmitting, by the operated-side computer, control information about playback of the moving image on the operated-side computer to the operating-side computer, based on the event information; receiving, by the operating-side computer, moving image data to be playback-controlled by the received control information about playback of the moving image; playing back, by the opera

Abstract: A spherical integrator has beam input and output apertures. The output aperture is opened at a position to which incident beam does not directly strike. The integrator has a curved inner surface which is a uniform diffusion surface. A galvanometer scanner has a mirror capable of adjusting a reflection angle of the beam from a light source such that a luminous energy beam reflected by the mirror to the input aperture is quantitatively varied. Beam from the light source is reflected by the mirror of the scanner to the input aperture of the integrator which diffuses and integrates the incident beam and outputs it through the output aperture.

Abstract: Mounted on a horizontal shaft 1 extending along surfaces of a film f are sprocket wheels 2 each having three tooth pairs 2a adapted to engage with perforations on the film. The tooth pairs 2a are angularily spaced apart from each other by 120 degrees around a periphery of the sprocket wheel 2. A triangular cam 11 is attached on one end of a horizontal shaft 7 rotatable in unison with the shaft 1. A lever 17 is attached to a horizontal shaft 15 carrying a cam follower 16 rotatable in unison with the rotation of the cam 11. A projection 20 which reciprocates registration pins 22 for engagement with and disengagement from the perforations g of the film f is fitted into an elongated slot 17a of the lever 17. A switching lever 14 is provided for displacement of the shaft 7 into a position where the shaft 7 is prevented from rotating even when the horizontal shaft 1 is rotated.
