摘要： A projector includes: a liquid crystal panel in which liquid crystal molecules to be irradiated with light from a light source are sealed; a polarizing plate disposed in a position to face the liquid crystal panel; and an optical compensation sheet disposed between the polarizing plate and the liquid crystal panel and compensating birefringence of the liquid crystal molecules. The optical compensation sheet can be adjusted by being swung in a plane orthogonal to the optical axis, and its normal can be adjusted so as to be tilted from the optical axis.

摘要： A central position detection section has a detection width in which the central position has a median value along one axial direction. When the direction from a position, which is located at the time at which returning is started toward the central position is defined as a go direction, the control section commands that a drive mechanism should sequentially perform following operations: a first operation of driving a the projection lens assembly in the go direction; a second operation of allowing the projection lens assembly to travel in a return direction at least by the detection width; and a third operation of allowing the projection lens assembly to travel in the detection width in the go direction by ½ of the detection width traveled in the go direction.

摘要： A projection display device includes: a light source; a rod-type integrator which unifies light emitted from the light source in intensity distribution; an imager which modulates the light emitted from the integrator; and an optical axis adjuster for adjusting an optical axis of the light source with respect to an incidence plane of the integrator. In this arrangement, the integrator has the incidence plane formed in the shape of a rectangle and inclines around an optical axis of the integrator with respect to an installation surface of a main body cabinet in which the light source is disposed. In addition, the optical axis adjuster shifts the light source relatively with respect to the incidence plane in a direction parallel to a shorter side of the incidence plane.

摘要： A projector comprises: a cooling fan for sucking ambient air through a filter; switching means for switching the operational mode of the cooling fan between a lowland mode and a highland mode; and control means adapted to obtain current fan voltage to determine the normal rpm value for that current fan voltage in reference to a highland voltage-rpm characteristic when the switching means is in the highland mode, obtain current fan rpm, and enables alarming means to issue a filter clogging alarm in the event that the current fan rpm is larger than the normal rpm value plus a predetermined value. Thus, filter clogging can be detected with precision in highlands.

摘要： A projection display device includes an imager portion which is arranged in a position closer to one side surface of a main body cabinet to modulate light and guide the light in a direction away from the side surface, and a projection portion. The projection portion is formed by a projection lens portion and a mirror portion which reflects the light through the projection lens portion toward a projection plane. The mirror portion is disposed so as to be shifted from an optical axis of the projection lens portion in a direction opposite to a direction in which the light from the projection lens portion is turned back. A control circuit portion and a holding member are disposed within a space produced between the projection lens portion and the main body cabinet due to a position gap between the projection lens portion and the mirror portion.

摘要： A projection type image display apparatus has a light source unit (11) that includes an arc tube (110) enclosed by a reflector (111) for reflecting the light emitted from the arc tube in one direction through its opening (111a). The opening (111a) of the reflector (111) of the light source unit (11) is covered with a transparent member (112). Formed in one side of the reflector (111), adjacent the opening is an air inlet port (113), while the side facing the air inlet port (113) is closed (i.e. has no port). Formed in the remaining two sides of the reflector (111), and adjacent the opening (111a), are air outlet ports (114) one for each side. This arrangement causes the cooling air to be uniformly circulated in the entire reflector (111) of the light source unit (11) without stagnation to regulate the temperature of the arc tube (110) in an easy and costless manner, and enables installation of the light source unit (11) at any angular position, free of angular limitation.
摘要翻译：投影型图像显示装置具有光源单元（11），该光源单元包括由反射器（111）包围的电弧管（110），用于通过其开口（111a）沿一个方向反射从电弧管发射的光。光源单元（11）的反射器（111）的开口（111a）被透明构件（112）覆盖。在反射器（111）的一侧形成有与开口相邻的空气入口（113），而面向空气入口（113）的一侧是封闭的（即没有端口）。在反射器（111）的其余两侧形成并与开口（111a）相邻的是空气出口（114），每侧有一个。这种布置使得冷却空气在光源单元（11）的整个反射器（111）中均匀地循环而没有停滞，以容易且无成本的方式调节电弧管（110）的温度，并且能够安装光源单元（11）处于任何角度位置，没有角度限制。
