摘要： An airflow rate sensor is provided with a through hole, and a detection unit is disposed inside the through hole. The airflow rate is calculated based on the output voltage resulting from the temperature difference and the like caused in the detection unit by the air flowing through the through hole. A duct is provided with a concave portion so as to protrude from outside the duct toward the inside thereof. The airflow rate sensor is disposed in the duct so as to cover the concave portion, in which the through hole is in communication with the space in the concave portion. The concave portion has a bottom provided with an opening. Accordingly, an installation structure of a sensor for reliably sensing a flow rate and a projector apparatus having the same are provided.

摘要： A lens shifter includes a fixed base and a movable base, which is movable relative to the fixed member and receives a projection lens. A drive mechanism applies driving force to the movable base. The drive mechanism includes a driver that generates force. A gear train transmits the force generated by the driver. A rack converts the force transmitted from the gear train into driving force for the movable base. The rack includes a tooth face extending along a tooth trace direction. A contact surface is formed only on part of the tooth face and receives the force from the gear train.

摘要： Elements of an optical system (12) of a projection type image display apparatus are stored in an optical system storage (46) having an upper opening in such a way that the optical element to be arranged close to a light source is fitted in the frame provided in the high-temperature region of the optical system storage (46) close to the light source, while the rest of the optical elements are respectively fitted in the frames in the low-temperature region of the optical system storage (46) remote from the light source. The upper opening in the high-temperature region is covered, in the low-temperature region, with a resilient metal lid (471), and, in the low-temperature region, covered with a resilient resin lid (472). Portions of these lids are partially cut into spring-like narrow strips having tips configured to firmly and accurately hold the lenses fitted in the respective frames, whereby the dimensional tolerances of the optical elements and the frames can be absorbed solely by the lids without resorting to any other parts.

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 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： 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 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.
