Abstract: A work machine control system includes: an acquisition unit configured to acquire a plurality of pieces of current topographical data indicating a current topography of a work site where a work machine performs work; and a combining unit configured to generate combined current topographical data of the work site in accordance with a predetermined rule based on the plurality of pieces of current topographical data acquired in the acquisition unit.

Abstract: A lamp socket device includes a socket body preferably made of a resilient material and a pair of electrically conductive terminals disposed therein and each including clamping portions having free ends bent as locking arms and a base having a locking hook bent from an upper edge thereof in a direction transverse to the locking arms. The locking arms and hooks are held in engagement with inner walls of the socket body which are positioned in mutually transverse relation. The terminals are thus easily and firmly mounted in place in the socket body against undesirable electric faults such as short-circuiting while the lamp socket device is used in a vibratory condition. Waterproof sealing characteristics and vibration resistance of the socket are improved by forming the socket body of resilient material.

Abstract: Disclosed is a device for simulation of projected image comprising a support member, a frame and an eye member attached respectively to the opposite ends of the support member. The relation between the size of the frame and the distance from the frame to the eye hole in the eye member is similar to the relation between the size of the projected image and the distance from the surface of the projected image to the viewer's seats. When the user looks through the eye hole at a given original and finds the contents of the image discernible, he is assured that a projection film to be produced by photographing the image enclosed with the frame, on being projected on a screen, will reproduce an image amply discernible by the viewers.
