Abstract: PROBLEM TO BE SOLVED: To provide a reflection type projector which allows light radiated to digital micromirror device (DMD) to accurately restrict to the contour of the DMD.
SOLUTION: An irradiation aperture having an opening part obtained by distorting the shape of a micromirror array of the DMD (a rectangle having an aspect ratio of 4:3) by an incidence angle (20°) is provided on the side of a light source lamp of an incidence optical system which radiated light of the light source lamp to the DMD. In the incidence optical system, the irradiation aperture and the DMD have a positional relation between an object surface and an image surface. Thus the shape of the opening part is deformed by the incidence angle and is imaged on the surface of the DMD, and this shape is an accurate shape of the micromirror array.

Abstract: PROBLEM TO BE SOLVED: To provide an electronic instrument and a device for displaying performance calorie consumption capable of measuring the calorie consumption by performance action of a player. SOLUTION: A database of calorie consumption by performance is stored in a ROM 11 or a hard disk 13, and this database is the one for calculating how much calorie has been consumed by performance action, based on performance information, for example, velocity and frequency of keystrokes, inputted from a keyboard 15. This device calculates calorie consumption based on the database every time the performance information is inputted, and notifies the player of the calorie consumption by displaying integration of the calorie consumption on a display part 17.

Abstract: PROBLEM TO BE SOLVED: To provide a calorie consumption measuring device in musical perfor mance capable of measuring the calorie consumption by player's performance operation and singing. SOLUTION: Performance sounds (including singing voice) inputted from a microphone 10 are converted to performance information such as MIDI data by a converting part 11. According to the performance information, a computing part calculates the consumption calorie of the performance by operation on required calorie for generating the sound of that sound level and that sound intensity. The computed result is integrated by an integrating part 14, and an integrated value is displayed on a display part 15. Thus, the calorie consumption amount by the performance operation of a musical instrument and singing is integrated to be noticed to a player.

Abstract: PROBLEM TO BE SOLVED: To automatically adjust the sound volume of a guide melody according to a singing state. SOLUTION: When a singer sings in a shrill at the start to of a singing period and the voice gradually approaches the interval of the melody and matches the interval of the melody at time t1, the sound volume of the guide melody is made large almost at time t0, and consequently the singer remembers the interval of the melody and sings in tune with the melody. As the difference between the interval of the singing and the interval of the melody decreases, the value of a sound volume control signal GC decreases and the sound volume of the guide melody also decreases correspondingly.

Abstract: PURPOSE:To provide the highly reliable digital communication system at a low cost. CONSTITUTION:After KARAOKE playing data from a computer 22 are processed into packets by an encoder 24, the encoder 26 applies EFM processing to the data. Then a modulator 28 modulates a carrier by EFM data and sends a modulation output to KARAOKE terminal equipment 30 via a communication line 10. A demodulator 32 of the KARAOKE terminal equipment 30 demodulates the modulation output to obtain EFM data, a decoder 34 decodes the EFM data, a decoder 36 implements un-packet processing and obtained KARAOKE playing data are stored in a memory 44. A MIDI player 46 is driven based on the KARAOKE playing data in the memory 44 to implement KARAOKE playing. Request data of a desired music are sent to the computer and then 2-way communication is attained.

Abstract: PROBLEM TO BE SOLVED: To provide a technique for localizing echo sound in a plurality of positions with a simple configuration. SOLUTION: A multi-tap delay circuit 14 of an echo device 1 outputs echo signals (first echo signals) resulting from delaying an original sound signal input to an input terminal 11 by delay times t11, t12, ..., t1n. A delay circuit 16 delay the first echo signals output from the multi-tap delay circuit 14 by a delay time t2 to output second echo signals. Gain controllers 172L and 172R amplify the first echo signals output from the multi-tap delay circuit 14 and output the amplified first echo signals to mixing circuits 18L and 18R. At this time, the gain controllers 172L and 172R amplify the first echo signals by different amplification factors. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a KARAOKE sing along machine network system which simplifies the configuration of KARAOKE sing along machine terminal sides and does not degrade the contents of services.
SOLUTION: A plurality of KARAOKE sing along machine terminals (30) and a common center office (20) are connected to each other by a LAN (Local Area Network) (10). The KARAOKE sing along machine terminals request the center station for music data of desired performance music. The center station transfers the music data corresponding to the requests to the terminals making the requests. The center station keeps channeling off the video data of a plurality of channels at all times independently from the transfer of the music data. Consequently, the terminal sides can reproduce the performance music based on the musical sound data included in the music data, can reproduce lyric images based on lyric data and further can select the video data and can reproduce animation image videos based on video channel assignment data.
