摘要： A normally open electromagnetic valve includes a fixed core, a movable core, a coil, a valve body, a valve seat member, a return spring, a raised portion formed at one of the fixed and movable core so as to project towards the other core and a recessed portion formed at the other core so as to face the raised portion. A relationship between the raised and recessed portions is set such that while a distance therebetween is within a predetermined range, an attraction force acting between the fixed core and the movable core by virtue of an excitation force of the coil decreases as the raised portion approaches or moves into the recessed portion, and when the valve body and the valve seat surface are brought into abutment with each other by exiting the coil, the distance between the raised portion and the recessed portion stays within the predetermined range.

摘要： The projection lens shifting mechanism is for locating the projected picture at a desired position on the screen by shifting the projection lens with respect to the display surface of the display device, including a base plate secured to the housing of the projection lens shifting mechanism and having a guide surface parallel to the display surface, a moveable plate rigidly holding the projection lens and movable in a prescribed direction parallel to the display surface guided by the guide surface, a holding plate linked to the moveable plate through elastic members, constituting, together with the moveable plate, an elastic clamp structure that holds the base plate and elastically clamps the base plate. When an external force works against the elastic force to release this clamp, the holding plate can move integrally with the moveable plate in a direction parallel to the guide surface of the base plate.
