A light source device includes a light source section that emits laser light, a reflection and diffusion member that diffuses and reflects the laser light emitted from the light source section, and a cooler that cools the reflection and diffusion member. The cooler includes at least one of an axial fan, an electronic cooling element, and a heat pipe.

An illumination light source system includes an excitation light source; a reflection/transmission member having a transmission area which transmits excitation light from the excitation light source and a reflection area which reflects the excitation light, the transmission area and the reflection area sequentially crossing an emission light path of the excitation light source; a fluorescent member provided in at least one of a reflection light path of the excitation light reflected by the reflection area and a transmission light path of the excitation light transmitted through the transmission area, the fluorescent member being provided with a phosphor which generates a color different from that of the excitation light by excitation with the excitation light; and a controller which reduces a light volume of the excitation light source while a boundary area between the transmission area and the reflection area of the reflection/transmission member is located on the emission light path.

An illumination light source device, comprising: a light path junction member which splits light emitted from a light source into a first light path emitting excitation light for phosphor and a second light path irradiating illumination light; a first diffuser disposed in the first light path; and a second diffuser disposed in the second light path, the second diffuser having a diffusion degree larger than that of the first diffuser.

An illumination apparatus emits light onto an optical modulation device for forming an image according to a modulation signal and illuminating an object. The illumination apparatus includes a light source; a fluorescent material that emits light of a color different from a color of light emitted by the light source; and a light guiding unit that switches between a state in which the light emitted from the light source is guided to the fluorescent material and a state in which the light emitted from the light source is not guided to the fluorescent material.

A polarization conversion element having plural polarization separation sections and plural phase modulation sections is disclosed. A light flux is separated into transmission light (P polarization) and reflection light (S polarization) by being input to a polarization separation section. The reflection light reflected at the polarization separation section is output in the same direction as that of the transmission light by being reflected again at an adjacent polarization separation section at a different position from a position where a light flux is input to the adjacent polarization separation section. The phase modulation section is disposed on an optical path of the transmission light or the reflection light and output light becomes the same polarization.

A delay circuit includes a first delay element, a second delay element, and an initializing section that measures a delay amount generated by the first delay element with respect to each delay setting value. The initializing section includes a first loop path that inputs an output signal of the first delay element into the first delay element and a second loop path that inputs an output signal of the second delay element into the second delay element. The initialization section includes a first measuring section that sequentially sets delay setting values mutually different from the delay setting value in the first delay element and sequentially measures delay amounts in the first delay element, a second measuring section that measures a delay amount in the second delay element, and a delay amount computing section that corrects a delay amount measured by the first measuring section.

摘要:
A hybrid saxophone is a combination of an acoustic saxophone and an electronic system, and the electronic system includes key sensors for monitoring the keys and a tonguing sensor for detecting the position of the tongue together with a breath sensor and a lip sensor, and the pieces of playing data are brought to an electronic tone generator for producing electric tones; the mouthpiece of the acoustic saxophone is replaced with another mouthpiece, which does not supply the breath to the reed, and a rotary type air-flow regulator is provided in the mouthpiece so that the player feels the blowing same as that in the acoustic saxophone.
摘要:
A picture reading apparatus with flaring light elimination capability, which includes a light source for emitting light, a contact glass with which a document to be scanned comes in contact, a lens array in which a plurality of lenses for converging the light from the light source are arranged at equal intervals therebetween, a roof mirror array in which a plurality of roof-like reflection surfaces are arranged corresponding to the plurality of lenses, a restricting plate for eliminating undesired light between adjacent lenses of the lens array, a housing in which the roof mirror array and the lens array are accommodated, a sensor, and a separation mirror. The apparatus further includes a light shield layer provided on the contact glass, at a portion other than a reading portion through which the light from the light source passes to scan the document, for eliminating undesired light, other than the converged light effective in supplying a picture signal.
