    摘要: Aspects of the invention provide a projector capable of comparatively easily achieving a contrast ratio higher than the original contrast ratio of the liquid-crystal light valve by a simple mechanism. The illumination light modulated by liquid-crystal light valves, i.e., image light, can be combined together in a cross dichroic prism, and then light intensity of suitable pixels is reduced by a proper amount by a liquid-crystal light valve, and then sent to a projection lens. The image light entering the projection lens can be projected to a projection surface. Because the light intensity of the image light formed by the liquid-crystal light valves is appropriately attenuated at suitable pixel areas by the liquid-crystal light valve, image light projection with a contrast ratio exceeding by far the contrast ratio achievable by the liquid-crystal light valves alone is possible due to cumulative light-intensity adjustment.

    摘要: A connector includes contacts each having a contact portion, an elastic portion and a fulcrum portion between the contact portion and a connection portion, and a pressure receiving portion; a housing fixing the contacts; and a slider having urging portions pivotally moved between the connection and pressure receiving portions of the contacts to urging the contact portions against the circuit board, thereby achieving reliable connection and miniaturization of the connector. In an aspect, the housing is formed on the side of a board insertion opening with a recessed portion for conducting the board. In another aspect, the contact includes upper and lower contact portions one above the other arranged alternately staggered so as to be connected to a circuit board having contact portions alternately staggered, so that no defective connection occurs, even if the circuit board is inserted erroneously upside down. In a further aspect, the connector further includes locking members having an engaging portion which engages an anchoring portion of the circuit board to prevent the circuit board from being removed. In one aspect, contacts of two kinds are inserted into the housing from opposite sides, respectively so that these contacts of the two kinds are into contact with the contact portions on respective surfaces of the circuit board. In a further aspect, moreover, a plate-shaped piece is provided in opposition to the contact portions of the contacts to prevent the housing from being deformed.

    摘要: A manufacturing method of an endless metal belt having metal rings built up and differing in circumference, includes the following steps of: a first circumference correction step of expanding each of the metal rings; and a second circumference correction step of expanding each of the metal rings after conducting a solution heat treatment to the expanded metal ring. In the manufacturing method, by executing the first circumference correction step and the second circumference correction step before and after the solution heat treatment, respectively, an expansion quantity for setting a circumference of each of the metal rings to become a predetermined length is attained.
