Abstract: An endoscope system includes an endoscope and a processor device that includes a system controller formed of an image control processor. The system controller determines whether or not the endoscope is a length measurement-compatible endoscope in a case where the endoscope is connected to the processor device, and enables switching of a mode to a length measurement mode in a case where the endoscope is the length measurement-compatible endoscope.

Abstract: An inverter includes: a housing base which includes a front area and a rear area opposite to the front area; a main body which is arranged in the front area of the housing base and houses a plurality of electronic components forming a power conversion circuit; a first duct which is arranged in the rear area of the housing base and includes a first end connected to an intake port of cooling air; a first heat sink which is arranged in the rear area of the housing base and includes a first fin and a first heat sink base extending perpendicular to an extension direction of the first duct; and a reactor which is arranged in the heat sink base in the rear area of the housing base, and generates heat at the time of energization.

Abstract: A stereoscopic display apparatus that performs a stereoscopic display using a right-eye image and a left-eye image acquired by radiographing a subject plural times while changing an incidence angle of radiation on the subject, includes a display unit that stereoscopically displays the right-eye image and the left-eye image, and a changing unit that shifts at least one of the right-eye image and the left-eye image displayed on the display unit to change an inter-image distance being a distance between the right-eye image and the left-eye image in a direction parallel to a straight line connecting the right eye and the left eye of an observer.

Abstract: A stereoscopic display apparatus that can perform a stereoscopic display using a right-eye image and a left-eye image acquired through radiography, includes an image display unit that can display a planar image of at least one of the right-eye image and the left-eye image as a planar display along with the stereoscopic display, a display selecting unit that selects any one of the stereoscopic display and the planar display, and a position pointing unit that can be operated in the selected stereoscopic display or planar display and that can be operated to interlock in the stereoscopic display and the planar display, wherein the position pointing unit includes a depth changing unit that changes the depth thereof in the stereoscopic display.

Abstract: A valve performance control apparatus has a low speed cam, a high speed cam, and an intermediate speed cam. A rocker arm is arranged between the cams and a valve. The rocker arm contacts the low speed cam. A pair of cam followers are reciprocally supported in the rocker arm to contact the high speed and intermediate speed cams. Lock members are slidably received in bores (or grooves) of the rocker arm. The lock members, when positioned in an unlocked position, permit the free reciprocation of the associated cam followers with respect to the rocker arm, which causes the valve to be driven by the low speed cam. When locked, the lock members abut against the associated cam followers and lock the cam followers to the rocker arm, which causes the valve to be driven by the cam with the largest profile. The lock member has an abutment surface, which contacts and is pressed by the cam follower.

Abstract: An engine has a crankshaft, a combustion chamber and a valve that selectively opens and closes the combustion chamber. The valve has a timing relationship to the crankshaft and lift characteristic. A control device hydraulically alters at least one of the timing relationship and the lift characteristic. A lubricant passage is connected with the control device to supply oil to a mechanism that is formed by engine parts slidably contacting one another within the engine. An auxiliary passage is provided for supplying the oil to the mechanism. Oil supplied from an oil pump to said auxiliary passage is restricted by an electromagnetic valve that is actuated based on the instruction from an electric controller when engine speed is lower than a predetermined value.

Abstract: An engine has a crankshaft, a combustion chamber and a valve. The valve opens and closes the combustion chamber. The valve has a lift characteristic that is altered by a control device according to a change of hydraulic pressure therein. The engine has a lubricant passage that is connected with an oil pump and supplies oil to a mechanism formed by parts slidably connecting one another within the engine. A hydraulic pressure passage extends into an interior of the control device to exchange the hydraulic pressure with the control device, thereby the control device is actuated to alter the lift characteristic. The oil pump supplies the oil to the pressure passage when connected with the pressure passage. The oil pan supplies the oil to the pressure passage when connected with the pressure passage. A switching valve selects one of the oil pump and the oil pan to connect the selected one with the control device based on the engine speed.

Abstract: There is disclosed a valve performance controller for an internal combustion engine. A camshaft is provided with a plurality of cams having different cam profiles. Changeover of the cams is performed through operation of a valve lift control mechanism. Also, a valve timing control mechanism is provided on the camshaft. The valve timing mechanism has a pulley, which is connected to a crankshaft of the engine via a timing belt. The pulley is connected to the camshaft via a ring gear. Through movement of the ring gear along the axis of the camshaft, the relative rotational phase between the pulley and the camshaft is changed. At least during cam changeover operation, oil is charged and retained within the hydraulic chamber located on both sides of the ring gear in the moving direction thereof. This structure reduces an impact which acts on the timing belt upon changeover of the cams.
