Abstract: A front liquid crystal display projector includes a housing having an exhaust port and a projection opening, an optical block, installed in the housing, having a light source, a reflection mirror, a light separator, an image display unit using liquid crystal, an image combining unit, a projection lens, and an exhaust fan installed between the light source and the exhaust port. The reflection mirror changes the direction of the light from the light source, and the projection lens and the light source are disposed parallel to each other. The exhaust port and the projection opening are provided at a first side of the housing. An image formed by the optical block is projected from the first side and from the projection opening, and air in the housing is discharged from the exhaust port and also from the first side. In addition, the exhaust port prevents stray light from the light source, which exits the exhaust port, from overlapping the image projected from the projection opening.

Abstract: A light source, a color separator, a plurality of liquid crystal panels, a polarizing plate, a color synthesizing optical unit, and a projecting lens are disposed. The color synthesizing optical unit includes an X prism, a bonding base, a panel retaining member, and a panel installing member. The panel retaining member is fixed on the bonding base. The liquid crystal panels and the polarizing plate are installed on the panel installing member. The panel installing member can be separated from the panel retaining member. By this configuration, deviation of the convergence can be prevented with respect to the liquid crystal panels. Further, in practical use, it is easy to replace or repair the liquid crystal panel or the polarizing plate.

Abstract: A microwave circuit includes a concentric-circle-like prominence (7) formed on a contact surface which is on the side of a metal body (3) serving as an external conductor of a coaxial line and which connects a conductor strip (1) of an MSL formed on a dielectric substrate (2) to an internal conductor of the coaxial line through a through-hole (9) extending from a ground plane (11) of the MSL through the dielectric substrate (2). The construction involves no mismatched portion and can prevent a loss and deterioration in VSWR in the coaxial-line/MSL conversion section, thereby making it possible to obtain satisfactory characteristics.

Abstract: A nut 13 is provided on a holding board 9 of a barrel 8 housing a projection lens. At both sides of a holding base 11 are supporting plates 12 having a stepping shape for presenting a sliding gap, and the holding board 9 is inserted in the sliding gap. At an upper corner of the holding base 11 is a pivot pedestal 14, and a shift rod 15 is attached revolvable to the pivot pedestal 14, the shift rod 15 having a screw portion 16 that engage with the nut 13. The projection lens moves up and down driven via nut 13 by revolution of the shift rod 15, for the height adjustment of projection lens.

Abstract: A liquid crystal display projector comprising a light source, a group of mirrors, liquid crystal display devices, a projection lens, a main body containing the light source, group of mirrors, liquid crystal display devices and projection lens, and a mechanism whereby the projection lens is allowed to retract into and protrude from the main body. The projection lens comprises an outer cylinder having a ring-like shape; a drive motor with a gear; a ring-like intermediate cylinder with a first cam groove, second cam groove and gearwork provided on the exterior thereof with the gearwork meshing with the gear of the drive motor and is installed on the inner side of the outer cylinder so as to be made movable by sliding; a first inner cylinder having a first axis to fit in the first cam groove and fits with the inner surface of the intermediate cylinder in the front portion thereof so as to be movable by sliding according to the movement of the first axis caused by the rotation of the first cam groove; a second inner cylinder having a second axis to fit in the second cam groove and fits toward the back of the inner surface of the intermediate cylinder so as to be movable by sliding according to the movement of the second axis caused by the rotation of the second cam groove; and a plurality of lenses installed in the cylinders at specified positions. The projection lens operates such that driving of the drive motor causes the intermediate cylinder to rotate and the rotation of the intermediate cylinder allows the projection lens to zoom by extending and retracting the first inner cylinder.
