A grasping tool which is attached to a device includes: a main body which is provided with two extending portions extending out in substantially the same direction and a connecting portion that connects respective one-side ends of the two extending portions; and a reinforcement portion that connects and reinforces a position different from that of the connecting portion, in the two extending portions. The main body and the reinforcement portion include an attachment portion that attaches the grasping tool to the device.

Grasping tool and projector

A projector includes a circulation cooling device, a controller that controls the projector, and an exterior housing that accommodates the circulation cooling device and the controller and forms the exterior of the projector. The circulation cooling device includes a cooling fan that blows a cooling gas to an object to be cooled, a heat absorber that absorbs heat of the gas having cooled the object to be cooled, and a relay section that forms, along with the closed housing, a closed space and relays electrical connection between the cooling fan and the controller, and the relay section includes a double-sided substrate having an inner surface which faces the closed space and on which a connection member electrically connected to the cooling fan is arranged and an outer surface which faces away from the closed space and on which a connection member electrically connected to the controller is arranged.

Projector

A projection system includes a first projector and a second projector. The projection system superimposes images projected from the first and second projectors on a projection surface and displays a projected image. The projection system includes a support configured to support the first projector and the second projector. The support supports the first projector and the second projector in positions where projection distances from the first projector and the second projector to the projection surface are different.

Projection system, support, and image display method

A projector includes: an external housing; and an exhaust fan configured to suck an air within the external housing and discharges the sucked air to the outside, the external housing has a top and bottom surface crossing a vertical axis, an air discharge port through that the air discharged from the exhaust fan is discharged to the outside, and a side surface that connects the top surface and the bottom surface, the exhaust fan constituted by a turbo fan that has an impeller rotatable around a predetermined rotation axis, and the rotation axis extends along the vertical axis.

A projector includes a light source; a light modulating device that modulates the flux of light emitted from the light source on the basis of image information to form an optical image; a projection optical system that projects the formed optical image; and an exterior housing that accommodates the light source, the light modulating device, and the projection optical system. An opening that introduces air from the outside of the exterior housing into the inside thereof is formed in the exterior housing. An object to be cooled, a duct connecting the opening to the objects to be cooled, and a filter purifying the air introduced from the opening are provided inside the exterior housing. A cooling fan that sucks the air having been purified through the filter and sends the air to the object to be cooled are provided in the duct.

A wind velocity measuring device is used in an electronic apparatus including cooled objects and cooling fans for cooling the cooled objects and measures a wind velocity of air blown to the cooled objects. The wind velocity measuring device includes a wind velocity measuring unit that measures a wind velocity of air, and an air circulating unit that circulates a portion of the air blown to the cooled objects. The air circulating unit includes barrier portions that extend to cross a circulation direction of the air at a front stage side of the circulation direction of the air, and an exhaust port that discharges inner air to the outside and is formed at a rear stage side of the circulating direction of the air, and the wind velocity measuring unit measures a wind velocity of the air between the barrier portions and the exhaust port in the air circulating unit.
