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.

摘要： A structure for cooling a semiconductor element includes an element body and a lead terminal extending from one surface of the element body in a direction intersecting the one surface. The semiconductor element cooling structure includes a heat sink. The heat sink includes a contact surface that is in contact with the one surface of the element body, a through-hole which is formed in the contact surface and through which the lead terminal passes, and a space portion that communicates with the through-hole and that is configured to house a substrate connected to the lead terminal.

摘要： A display device is provided with a plurality of solid-state light sources (101-103) and a coolant-circulating means (100) that is equipped with a flow path (100a) formed to pass through each of the solid-state light sources (101-103) and that circulates a coolant via the flow path (100a). Each of the solid-state light sources (101-103) has the property that the luminance thereof changes in response to a temperature change. The flow path (100a) is formed such that the coolant first passes through solid-state light sources having a greater degree of luminance change according to the above-described property of the solid-state light sources (101-103).

摘要： A vehicle brake fluid pressure control apparatus includes a control unit including a memory part for storing a valve closing map which shows a relationship between a differential pressure between an upstream side and a downstream side of a pressure regulator valve and an output current value for closing the pressure regulator valve and a valve opening map which shows a relationship between the differential pressure and an output current value for opening the pressure regulator valve. The control unit executes a current value switching control in which the output current value of the valve closing map is changed to that of the valve opening map and thereafter, the output current of the valve opening map is changed to an output current value which lies somewhere between the output current values of the valve closing map and the valve opening map.
