摘要:
A pipe joint for connecting water supply pipe together and which utilizes compression seals between the pipe and the joint, and is comprised of a holding housing having a band body that surround a seal ring and a holding ring. A locking bolt is threadably tightened onto the holding housing. The seal ring is embedded and sealed within outside surface of both ends of the separated pipes after the locking bolt is threadably tightened. The holding ring is positioned to engage and become fully engaged within the groove at each of outside of the separated pipes, and hold the separation pipes against being easily separated after the locking bolt is threadably tight-end onto the holding housing.

A pipe joint for connecting water supply pipe together and which utilizes compression seals between the pipe and the joint, and is comprised of a holding housing having a band body that surround a seal ring and a holding ring. A locking bolt is threadably tightened onto the holding housing. The seal ring is embedded and sealed within outside surface of both ends of the separated pipes after the locking bolt is threadably tightened. The holding ring is positioned to engage and become fully engaged within the groove at each of outside of the separated pipes, and hold the separation pipes against being easily separated after the locking bolt is threadably tight-end onto the holding housing. The ring spring having a turned up portion eliminate swell out of the holding ring from the holding housing, and circumference rotation by itself. The ring expander creatable enlargement of circumference clearance between adjacent segment of the holding ring allowed the diameter enlargement of the holding ring against compress force of the ring spring. The setting member maintainable diameter enlargement of the holding ring after removal of the ring expander is at ease of prior to installing of the pipe joint for connecting the separated pipes.

A projection type display apparatus includes a housing having a first side on which an air intake opening is arranged and a second side on which an air exhaust opening is arranged, a light source for supplying light, and a light valve device which modulates the light output from the light source. A first fan is provided which draws air from the air intake opening into the housing, and a first ventilation path is coupled with the air intake opening so as to lead air flow from the air intake opening toward a lower portion of the light valve. A second ventilation path is formed from the lower portion of the light valve to an upper portion of the light valve, and a second fan is provided which draws out air flowing from the second ventilation path through the air exhaust opening to outside of the housing.

A liquid crystal projector comprises an illuminating optical system including a light source, a color separating optical system for separating illuminating light rays emitted by the illuminating optical system into light rays of three colors, a projection lens unit comprising a projection lens, a cross dichroic prism disposed near a light receiving end of the projection lens, and a plurality of liquid crystal panels arranged around the cross dichroic prism, and a light source power supply for supplying power to the light source. The projection lens unit, the color separating optical system, the illuminating optical system and the light source power supply are arranged in that order. The liquid crystal projector has an outside size in a horizontal plane of 263 mm by 318 mm or below. The liquid crystal panels have a display screen size of 0.9 in. A cooling fan for cooling the plurality of liquid crystal panels is disposed beside the projection lens.

A projective display apparatus having an illumination unit which includes a light source, an integrator lens and a collimator lens, a light splitter unit which splits light beams from the illumination unit into a plurality of color components, a plurality of light valves, a cooling fan, and a wind guiding unit. A respective one of the light valves corresponds to a respective one of the color components. The wind guiding unit guides the cooling wind from the cooling fan to the illumination unit and the light valves. The wind guiding unit splits and forms at least two branch wind guiding paths. One of the branch wind guiding paths guides cooling wind from the cooling fan to the illumination unit and another of the branch wind guiding paths guides the cooling wind to the light valves.

A projection type display apparatus includes a housing having a first side having an air intake opening and a second side having an air exhaust opening, a light source for supplying light, and a light valve device which modulates the light output from the light source. A centrifugal fan is associated with the air intake opening so as to draw air from the air intake opening. A first ventilation path is coupled with the air intake opening so as to lead air flow from the air intake opening toward a lower portion of the light valve, and a second ventilation path is formed from the lower portion of the light valve to an upper portion of the light valve. An exhaust fan is associated with the air exhaust opening so as to draw out air flowing from the second ventilation path through the air exhaust opening.

An optical equipment having a discharge lamp for supplying light and a light valve device for projecting the light from the equipment having an air intake opening arranged on one side of the equipment. A ventilation device is associated with the air intake opening so as to draw in air from outside of the equipment through the air intake opening and a ventilation path arranged so as to extend from an outlet of the ventilation device continuously. The ventilation path includes a partition member proximate to an outlet of the ventilation device and air flow through the ventilation path is divided into a plurality of air flows by the partition member so as to cool different parts of the light valve device respectively.

摘要:
A display device, such as a reflecting type liquid crystal projector, in which dust is prevented from becoming attached to a reflecting type light valve, such as a liquid crystal panel, and an improvement in cooling effect are attained. The device has a structure having a partition wall for forming an enclosed space including at least an incidence/emission optical system of the reflecting type light valve. The reflecting type light valve is provided in the partition wall such that a light incidence/emission surface of the light valve faces into the side of the enclosed space. A part opposite to the light incidence/emission surface of the reflecting type light valve faces outside the enclosed space. In a structure where a cooling arrangement or a thermal conductive partition wall is connected to the part opposite to the light incidence emission surface, the cooling effect is further improved.
