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： An illumination apparatus includes a reflector including a parabolic or ellipsoidal mirror, a light source arranged near a (first) focal point of the reflector, and a front mirror having a transparent window and a mirror surface symmetrical about the light axis. Luminous flux emitted from the light source is reflected from the reflector. In the case of the parabolic mirror, the front mirror has the same size as an entrance of an output light utilizing optical system, and the luminous flux exits toward the optical system as collimated light. In the case of the ellipsoidal mirror, the front mirror is arranged between two focal points of the ellipsoidal mirror, and the luminous flux is directed toward the second focal point. However, at least one part of the luminous flux is reflected from the front mirror and returned toward the first focal point.

摘要： A light-source device includes an excitation light source to emit first color light; an optical member having a reflecting surface to reflect the first color light; a wavelength conversion unit including a wavelength conversion member on which the first color light reflected by the optical member is incident, the wavelength conversion member to convert at least part of the first color light into second color light having a wavelength different from a wavelength of the first color light and emit the second color light; and a light condensing element to condense the first color light emitted from the wavelength conversion unit. A straight line including a first optical path from a center of a flux of light rays emitted from the excitation light source, to the center of the first color light on the reflecting surface does not intersect with a light flux condensed by the light condensing element.

摘要： A light source device comprising: a light source section which generates any one of blue light, red light, and green light; a phosphor which generates a fluorescence including the two colors other than the color of the light emitted from the light source section; a color-changing section which changes one of the two colors of the fluorescence emitted from the phosphor to another color regularly and irradiates it to the image-forming element; and a light path-switching section which switches a light path in which a fluorescence excited by the color light emitted from the light source section passes towards the color-changing section and a light path in which the color light emitted from the light source section passes towards the image-forming element regularly.
