Disclosed is a trimethine dimer compound represented by the following general formula (I) and optical recording medium containing such a compound in a recording layer. (I)(In the formula, symbols are as in the description. When both Xa2 and Xb2 are imino groups, one of Xa1, Xb1, Xa3 and Xb3 is necessarily a 1-alkyl-1-benzylmethylene group which may have a substituent, a 1,1-dibenzylmethylene group which may have a substituent or a cycloalkane-1,1-diyl group having 3 to 6 carbon atoms which may have a substituent.)

A phthalide compound of general formula (I) and a near infrared absorber and a recording material each utilizing the phthalide compound are disclosed. ##STR1## wherein ring A represents a substituent group of the following formula ##STR2## where the other substituents are as defined in the disclosure. The near infrared absorber and the recorded image on the recording material absorb strongly the near infrared region with no appreciable absorption in the visible region of the spectrum. The near infrared absorber is colorless or pale in color and yet highly capable of absorbing near infrared radiation. The recorded image on the recording material can hardly be read with the eye but can be read with the OCR. Moreover, the effect on the developed shade of any concomitant color former in a recording material is minimal.

In the present invention, a CPU obtains the number of notes for each skill type from note data included in a phrase segment for which musical performance input has been performed, compares the note data included in the phase segment for which the musical performance input has been performed and musical performance data inputted by the musical performance so as to obtain the number of correctly played notes for each skill type, and accumulates evaluation values for the respective skill types each found by multiplying an accuracy rate for each skill type obtained from the obtained number of notes and the obtained number correctly played notes for each skill type by a skill value of each type so as to obtain an overall musical performance evaluation value.

A musical score extracting unit specifies areas of each of measures and the measure number of each measure on a musical score based on positions of musical-score composing elements such as part lines, staffs and bar lines. A music-data dividing unit divides music-data file based on time information in the music-data file to generate plural unit music-data files containing pitch information and time information for one measure. The music-data dividing unit specifies measures where repeat marks are placed based on sorts and positions of the repeat marks and positions of the part lines, staffs and bar lines on the musical score, thereby removing unit music-data file to repeat as instructed by the repeat marks from the plural music-data files to obtain a final unit music-data files associated with the respective measure numbers.

An exemplary method for a producing a piezoelectric vibrating piece having at least one mesa step includes forming a metal film on a main surface of a piezoelectric wafer. A through-groove is formed through the thickness of the wafer to form a plan profile of a desired piezoelectric substrate. A film of photoresist is formed on the surface of the metal film. A resist is applied, exposed, and formed into a resist pattern that defines a first mesa step along at least a portion of the plan profile. In regions not protected by the metal film, the piezoelectric substrate is etched to a defined depth to form a mesa step. The denuded edge surface of the metal film is edge-etched. A second mesa step, inboard of the first mesa step, can be formed by repeating the edge-etching and substrate-etching steps using the metal film as an etch protective film.

The present disclosure provides a mesa-type AT-cut quartz-crystal vibrating piece, in which amount of the vibrating unit is adjusted to appropriate amount, in order to inhibit unnecessary vibration and to prevent degradation. The mesa-type AT-cut quartz-crystal vibrating piece (30) for vibrating piece vibrates at 38.400 MHz comprises a rectangular excitation unit (31), a peripheral region (32) formed in periphery of the excitation unit and thinner than the excitation unit. The thickness difference h (μm) between one principal surface of the excitation unit and the adjacent peripheral region is obtained by the following equation: h=(0.2×Mx)−143 The length of the x-axis direction of the crystallographic X-axis is Mx (μm).
