Abstract: An impeller element includes a plurality of blades disposed along an outer circumference of a circular support plate. Each blade is divided into a plurality of blade sections in a rotational axis direction. At least one of the divided blade sections as a long-chord blade section is configured such that a chord as a line segment connecting a blade outer-circumferential edge and a blade inner-circumferential edge of the blade in a cross section perpendicular to a rotational axis of the blade has a greater length than a chord of another one of the blade sections as a short-chord blade section. The blade inner-circumferential edge of the at least one long-chord blade section having the longer chord protrudes toward the inner circumferential side, relative to the blade inner-circumferential edge of the at least other one of the blade sections as the short-chord blade section having the shorter chord.

Abstract: A cross flow fan including an impeller having at least two rings arranged with intervals in a fan rotation axis O direction and a plurality of blades that are arranged, between correlated rings, with intervals in a circumferential direction of the rings, in which the blade is divided into plural areas in the fan rotation axis O direction, and both ends adjacent to the rings are denoted as the blade-ring proximate sections and the center portion of the blade is denoted as the inter-blade-ring center section. The blade is formed such that the thickness of the inner peripheral blade end of the blade that is the inner peripheral end of the impeller is smaller in the inter-blade-ring center section than in the blade-ring proximate section.

Abstract: This projector comprises a source lamp, a lamp storage portion, storing the source lamp therein, including an air discharge opening for discharging internal air from the lamp storage portion and a netlike member so arranged as to cover the outer side of the air discharge opening of the lamp storage portion for inhibiting fragments of the source lamp from being discharged outward from the lamp storage portion through the air discharge opening when the source lamp is broken. The lamp storage portion further includes a protrusion provided on the outer side surface close to the air discharge opening to protrude in a direction intersecting with the extensional direction of the netlike member with a function of inhibiting the fragments of the source lamp from passing through a clearance between the lamp storage portion and the netlike member.

Abstract: An angle adjusting mechanism (3) of a video projector (1) comprises a support (31) which can be pulled out downward from a bottom (2e) of a lower housing member (2b) to protrude a desired height, a lock member (32) to lock movement of the support (31), a link lever (33) to release locking of the support (31) by the lock member (32) when it is moved, and an operation button (35) having a top end portion (35e) inserted into a button hole (2c) of a upper housing member (2a) and movably held on a mounting base (33b) of the link lever (33) in a direction substantially parallel to the top face (2d) on which the button hole (2c) is formed.

Abstract: The invention provides a remote controller which can prevent a discordant rattle noise and an operation sound of a button from being generated without deteriorating operability of the button.

Abstract: A lens cap of a projector has a front portion covering a lens and a cylindrical side portion. The front portion has an opening to which a prescribed string holding member is attached. The string holding member is formed to have a pair of engaging portions, a string inserting portion, a cover portion and a guide groove. The pair of engaging portions are engaged with the opening formed in the lens cap. A string is inserted through the string inserting portion, and the string is retained as a knot of the string prevents the string from being pulled out. The cover portion covers the opening with the string holding member engaged in the opening. The guide groove is formed on the back side of the cover portion, and guides the string from the back side to the front side of the front portion of the lens cap. Thus, the lens cap can easily be put on the focus ring without any interference with the front panel.

Abstract: In a circular opening of an upper surface of a chassis, a disk-like zoom adjusting knob and a circular ring-like focus adjusting knob are disposed so as to be rotatable.

The zoom adjusting knob, zoom interlocking mechanism, and zoom adjusting member and the focus adjusting knob, focus interlocking mechanism, and focus adjusting member are fitted to a common body structure to construct a projecting optical unit.

Abstract: A post in a fluid passage for passing a fluid flow extends across a part of the fluid flow; a measuring duct in the post extends through the post; and a flow rate detector is located in the measuring duct. The measuring duct has a fluid introduction port with an elongated shape, the measuring duct is constricted and has at least a portion located between the fluid introduction port and the flow rate detector, substantially smoothly narrowing toward a downstream direction of the flow in a longitudinal direction of the elongated shape.

Abstract: A diversion passage is constructed into an inverted U shape in which an upstream diversion passage and a downstream diversion passage each having a passage direction in a direction of projection of a detector flow tube communicate by means of a curved portion. An inflow port is constructed by removing a portion of a wall of the upstream diversion passage on an upstream side in the main direction of flow, and removing a portion of first and second side walls of the upstream diversion passage facing each other in a direction perpendicular to the main direction of flow and the direction of projection of the detector flow tube. In addition, a wall surface on a downstream side of the upstream diversion passage in the main direction of flow at the inflow port is formed into a curved surface shape that is gradually displaced upstream relative to the direction of projection of the detector flow tube to constitute an air lead-in surface.

Abstract: A rib, provided on an outer periphery of a projection ring, includes: a first rib extending along a direction in which an optical axis of a lens main body extends (an attachment direction of a focus lens); and a second rib, brought into contact with one end of first rib, extending along a direction approximately orthogonal to first rib so as to have one side and the other side. On the other hand, a protrusion, provided on an inner periphery of the cylindrical focus ring, includes a pair of protrusion parts arranged with a spacing in a direction in which an optical axis extends. With this structure, it is possible to obtain a projector having a focus ring capable of being easily attached to a lens main body and being easily molded.

The string holding member is formed to have a pair of engaging portions, a string inserting portion, a cover portion and a guide groove.

A string is inserted through the string inserting portion, and the string is retained as a knot of the string prevents the string from being pulled out. The cover portion covers the opening with the string holding member engaged in the opening. The guide groove is formed on the back side of the cover portion, and guides the string from the back side to the front side of the front portion of the lens cap. Thus, the lens cap can easily be put on the focus ring without any interference with the front panel.
