    • A liquid cooling type projector is provided with greater flexibility to meet different screen sizes of a projection television and, thus, contributes to the reduction of production cost. The projector has a cylindrical frame containing a projection lens unit mounted by a liquid-tight member thereto and coupled at a rear end to a CRT in liquid-tight arrangement such that a liquid-sealing space is established between the projection lens and the CRT. In particular, the projection lens unit is arranged so as to be movable with respect to the frame along its optical axis. Also, the liquid-tight member is arranged to maintain the liquid-tight condition regardless of the position of the projection lens unit relative to the frame. Thus, the projection lens unit can arbitrarily be displaced towards and away from the CRT, increasing a focusing range. Accordingly, the projector will successfully be matched to different sizes of projection screens contributing to the reduction of the production cost of projection televisions.
    • 液体冷却型投影仪具有更大的灵活性以满足投影电视的不同屏幕尺寸,并因此有助于降低生产成本。 该投影仪具有圆筒形框架,该框架包含由液密构件安装在其上的投影透镜单元,并且在后端以液密方式耦合到CRT,使得在投影透镜和CRT之间建立液体密封空间。 特别地,投影透镜单元布置成可沿其光轴相对于框架移动。 另外,无论投影透镜单元相对于框架的位置如何,液体元件被布置成保持液密状态。 因此,投影透镜单元可以任意地朝向和远离CRT移位,从而增加聚焦范围。 因此,投影机将成功地匹配不同尺寸的投影屏幕,有助于降低投影电视的生产成本。

    • A coupled lens assembly comprises a plurality of lens units coupled by an intermediate layer disposed between the adjoining lens units, the intermediate layers being formed of an additional type silicone filler. A coupled lens assembly comprises a plurality of lens units coupled by an intermediate layer disposed between the adjoining lens units and formed of a bonding agent. Each of the lens units has a central lens portion and a peripheral portion surrounding the central lens portion and wherein one of the adjoining lens units has a flanged portion formed to a peripheral portion and the other one of the adjoining lens units has an engaging portion formed to the peripheral portion to be engaged with the flanged portion when both the lens units are coupled with optical axes of both the lens units being aligned. A groove is formed to at least one of the peripheral portions of the adjoining lens units for receiving an excessive fillet such as bonding agent when the filler is excessively applied and/or a discharge passage is formed to at least one of the peripheral portions of the adjoining lens units for discharging the excessive filler outward the coupled lens assembly. The groove may be formed so as to communicate with the discharge passage.
    • 耦合透镜组件包括通过设置在相邻透镜单元之间的中间层耦合的多个透镜单元,中间层由附加型硅氧烷填料形成。 耦合透镜组件包括多个透镜单元,该透镜单元通过设置在相邻透镜单元之间并由粘合剂形成的中间层耦合。 每个透镜单元具有中心透镜部分和围绕中心透镜部分的周边部分,并且其中一个邻接的透镜单元具有形成于周边部分的凸缘部分,并且相邻透镜单元中的另一个具有形成的接合部分 当两个透镜单元与两个透镜单元对准的光轴耦合时,到与凸缘部分接合的周边部分。 在邻接的透镜单元的周边部分的至少一个周边形成有凹槽,用于当填料过度施加时,接收诸如粘结剂的过多的圆角和/或排出通道,形成至少一个周边部分 相邻的透镜单元,用于将过量的填料向外耦合到耦合的透镜组件。 凹槽可以形成为与排出通道连通。

    • A lens frame consists of a lens barrel with a built-in projection lens and a support member in which the lens barrel is inserted and supported. The lens barrel has on its outer surface a pair of axially spaced projections as a slide member. The support member has on its inner surface projected guide strips that extend inclined with respect to a plane perpendicular to the axis of the support member. The support member also has axially extending ribs on the inner surface that tightly engage with the outer surface of the lens barrel as the latter is inserted into the former, in order to keep their axes aligned. With the lens barrel inserted and the projected guide strip received between the paired projections, the lens barrel is rotated and the paired projections are guided along the inclined projected guide strip, causing the lens barrel to move forward or backward in the axial direction. In this way, the focus adjustment can easily be made. The tight engagement between the ribs and the lens barrel produces contact friction that helps prevent the lens barrel from being turned inadvertently after the focus adjustment is made.
    • 透镜框架由具有内置投影透镜的镜筒和支撑构件组成,其中透镜镜筒被插入和支撑。 镜筒在其外表面上具有一对作为滑动构件的轴向间隔开的突出部。 支撑构件在其内表面上具有相对于垂直于支撑构件的轴线的平面倾斜延伸的突出导向条。 支撑构件还具有在内表面上的轴向延伸的肋,当其插入到前者中时,其与透镜镜筒的外表面紧密接合,以便保持它们的轴线对准。 在插入透镜镜筒并且将投影的引导条接收在成对的突起之间的情况下,透镜镜筒旋转,并且成对的突起沿着倾斜的突出的导带被引导,使得镜筒在轴向上向前或向后移动。 以这种方式,可以容易地进行焦点调整。 肋和镜筒之间的紧密接合产生接触摩擦,这有助于防止在进行焦点调节之后镜筒被无意地转动。
