An object is to readily visualize a propagation state of sound emitted within a sound space. A sound to light converter includes: a microphone; a light emitting unit; and a light emission control unit that acquires an instantaneous value of an output signal from the microphone in synchronization with a strobe signal and that allows the light emitting unit to emit light with a luminance level corresponding to the acquired instantaneous value. The strobe signal is generated and output in a signal generator of the sound to light converter. Alternatively, the strobe signal is generated and output in a control device of a sound field visualizing system in synchronization with an emission of sound to be visualized by the sound to light converter.

A blade front edge of a turbo fan has, between a main-plate-side blade front edge and a shroud-side blade front edge, a projecting blade front edge which distances away from a blade rear edge (located in a rotation direction A) as it furthers away from a main plate, which curves to a position away from a rotation center, and, in a range close to the main plate, a main-plate-side front-edge skirt portion which distances away from the blade rear edge and inclines away from the rotation center as it becomes closer to the main plate. On the other hand, a main-plate-side blade rear edge, which is a range close to the main, plate of the blade rear edge, is substantially perpendicular to the main plate and a shroud-side blade rear edge, which is a range close to a shroud, is inclined so as to gradually distance away from the blade front edge (behind in the rotation direction A) as it furthers away from the main plate.

A display device has a light source that radiates light from a light-emitting portion. A light guide body receives an incident light from the light-emitting portion of the light source and emits light. A display element is illuminated by light emitted from the light guide body and has a color filter having a coloring layer of RGB. A filter layer reflects components of light having a wavelength in a preselected region of 570 nm to 590 nm among the light radiated from the light source and emitted from the light guide body. A phosphor is excited by the components of light in the preselected region reflected by the filter layer and emits red light that passes through the filter layer and through the color filter of the display element.

To provide a lighting device capable of a substantial color adjustment and unlimited control of spectral components, a lighting device of the present invention puts a first transparent plate in which a phosphor layer dispersed with a first phosphor is formed in places and a second transparent plate in which a phosphor layer dispersed with a second phosphor is formed in places in a path of light from a light source, and stacks the first transparent plate and the second transparent plate on top of each other. The second phosphor differs from the first phosphor. How much in terms of area the phosphor layers overlap with each other is made variable, and the color tone of the lighting device can thus be controlled. The lighting device uses a blue light source as its light source, a green phosphor as the first phosphor, and a red phosphor as the second phosphor. An intended chromaticity can be obtained by varying how much in terms of area the green phosphor layer and the red phosphor layer overlap with each other and thereby adjusting the green light absorption amount of the red phosphor.

A lighting device surface-emits light from a light emitting surface of a light emitting element and guides the emitted light using a light guide member. The lighting device has a first wavelength conversion member for converting light emitted from the light emitting device into light having a first peak wavelength and a second wavelength conversion member for converting light emitted from the light emitting device into light having a wavelength shorter than the first peak wavelength. The first wavelength conversion member is provided between the light emitting element and the light guide member and is contained in a resin potting the light emitting element. A film has a layer containing the second wavelength conversion member. The film is provided on a light emitting surface side of the light guide member.

An illumination device for emitting light includes a light incident body having a first end portion that has a light incident surface on which light from a light source is incident, a second end portion, and an outer oval-shaped surface portion interconnection the first and second end portions. A light guide plate is optically coupled to the second end portion of the light incident body and has a light emitting surface through which light that propagates through the light incident body is emitted. The light guide plate and the light incident body are integrally formed and may comprise a one-piece body. A display device utilizes the illumination device for illuminating a display element of the non-self light emitting type.

A thin illumination device with a high efficiency of utilizing light and a display element using the same are realized. In an illumination device according to the present invention, a light incident body (3) having a light incident surface (4) is optically coupled to a light guide plate (2), light coming from a light source (1) being incident on the light incident surface (4). At least part of the light incident body between the light incident surface (4) and the light guide plate (2) is oval in cross section.
摘要:
An automatic transaction apparatus for allowing users to deposit money in the form of financial documents such as checks has a depository inlet, a document feed mechanism, a reading mechanism, a printing mechanism, and a storage mechanism, all for automatically settling financial documents deposited by users. The depository inlet has a guidance mechanism for indicating a pattern in which to insert the financial document into the depository inlet. According to the pattern indicated by the guidance mechanism, the user can insert the financial document with face and back sides properly directed and in a proper orientation into the depository inlet. Since the financial document is properly inserted into the depository inlet, the automatic transaction apparatus may have a relative simple document deposition mechanism for processing the inserted financial document as the document deposition mechanism does not need to handle financial documents inserted in different patterns.

Blades forming a turbofan included in an indoor unit each have, in a blade outer-circumferential surface of the blade and near a blade rear-edge portion, a plurality of rear-edge horizontal grooves extending horizontally (in a plane perpendicular to a center of rotation) with predetermined lengths L2 reaching the blade rear-edge portion. The rear-edge horizontal grooves are each a combination of a groove recessed portion provided with a predetermined depth in the blade outer-circumferential surface and a groove wrapping portion continuous with the groove recessed portion and provided at the terminal end of the blade rear-edge portion. The rear-edge horizontal grooves are provided in a region extending upward from the main plate defined by a distance H1 and in a region extending downward from the shroud defined by a distance H2.
