  • Publication number: 20140061535
    Abstract: A liquid crystal composition in which deterioration of viscosity that is associated with an increase in ?n and an increase in ?? is suppressed, and a liquid crystal display element having a markedly improved response speed by using the relevant liquid crystal composition. The liquid crystal composition has a large value of ?n and negative ??, and have large absolute values thereof. Also, the liquid crystal composition has low ?, has excellent liquid crystal properties, and exhibits a liquid crystal phase that is stable in a wide temperature range. Furthermore, since the liquid crystal composition is chemically stable to heat, light, water and the like, the liquid crystal composition is capable of low voltage driving, and is practically useful and highly reliable.

  • Publication number: 20120120231
    Abstract: A first optical system irradiates a target with a detecting wave and making the detecting wave that is transmitted through the target incident upon the electrooptical crystal. A second optical system slants a pulse plane of a probe wave relative to a pulse plane of the detecting wave and making the probe wave incident upon the electrooptical crystal. A camera detects the probe wave passing through the electrooptical crystal. The first or second optical system includes a compensating component which partitions a beam cross section of the detecting wave or the probe wave into unit areas. The optical component makes different an optical path length of a beam passing each unit area and compensates a phase shifting between the pulse plane of the detecting wave and the pulse plane of the probe wave at positions in a crossing direction of a surface of the electrooptical crystal and the virtual plane.

  • Patent number: 8070342
    Abstract: A light emitting element is mounted on the surface of a board. The light emitting element emits light. The light passes through a translucent optical member. The light enters the translucent optical member through a incident surface. The lines of protrusions make the incident surface jagged. The jagged surface resulting from the protrusions enables diffusion of the light entering through the incident surface. The light spreads along the surface of the board. Simultaneously, the emitted light is partly reflected on the incident surface. The reflected light is reflected on a reflecting surface placed behind the light emitting element. The reflected light then enters the translucent optical member. The translucent optical member is thus allowed to illuminate over a wide range with a sufficient brightness. An impressive illumination can be realized.

  • Patent number: 5763802
    Abstract: A chord analysis apparatus which includes a table memory for memorizing a plurality of sound timing patterns in a performance section of a predetermined number of beats, a plurality of tone pitch difference patterns corresponding with the sound timing patterns and a plurality of harmonic tone information data corresponding with the tone pitch difference patterns. In the tone pitch difference patterns, each difference in tone pitch between adjacent tones is represented by the number of semitones. After a performance information data of a desired musical tune has been divided each at two times, a pattern corresponding with the sound timing and tone pitch difference patterns in each divided section is searched at the table memory to read out a harmonic tone information data corresponding with the searched pattern thereby to detect each chord of the divided sections based thereon.

  • Patent number: 5492049
    Abstract: In a pattern memory are stored plural performance patterns, each of which has one or more measures. Plural ones of the performance patterns are optionally selected and read out from the pattern memory, so as to make a music piece made up of time-series combinations of the selected performance patterns. The thus-made music piece is stored into a song memory. A suitable device such as a switch or a detector or a suitable process is employed to instruct to make a music piece in auftakt form. For this purpose, such a method may be employed, for instance, where it is detected that the melody part is in the form of an auftakt music piece, and in response to this detection, it is automatically instructed that the music piece made up of combinations of the performance patters should also be made in auftakt form.

  • Patent number: 5484957
    Abstract: In an automatic arrangement apparatus, a melody of a part of an original musical tune is memorized in a melody memory (4), chord data of the original musical tune is memorized in a chord progression memory (5), and a rhythm pattern in a rhythm pattern memory (12) is selected in accordance with the style and composition of the original musical tune. At a timing of a note code of the selected rhythm pattern, a top-note, an additional tone, a bass part and a drum part are produced. The top-note is produced by referring to a top-note table stored in a top-note table memory (15) and corresponds with the chord. The additional tone is produced in accordance with the top-note and the chord on a basis of a voicing table stored in a voicing table memory (16). The top-note and additional tone can be selected at a continuous two-tone pair.
