摘要:
There is disclosed a process for producing iron and refractory material for use as a raw material for a refractory brick and as an aggregate for a castable refractory product. A mixture of aluminum smelting residue and scale is introduced into a furnace. The mixture is melted in the furnace and a thermit reaction is generated. After the completion of the thermit reaction, a molten iron and a molten slag are cooled. Particularly the molten slag is gradually cooled. The slag is crushed to form the refractory material.Alternatively, in order to produce iron and alumina cement, quicklime and/or limestone are further introduced into the furnace. The molten slag is cooled rapidly to form a clinker. The clinker is crushed to a powder size to form the alumina cement.

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).

A sash window includes two window frames disposed in lateral juxtaposition and each including a head member, a sill member and a pair of jamb members connected together into a rectangular configuration, and a pair of upper and lower sashes supported within a respective one of the window frames. A sill nose facing member is mounted to exterior sides of the sill members and extends continuously from an outer end of one sill member to an outer end of the other sill member. Each window frame has miter joints at corners thereof so as to provide sufficient structural strength. The miter joints formed between the sill member and the jamb members are covered or concealed and do not deteriorate an aesthetic appearance of the sash window.

A reduction gear capable of satisfying, at high level, each of: realizing a high reduction ratio; preventing backlash by securing rotation smoothness; and carrying out compactification and weight saving of entire mechanism is provided. The reduction gear of the invention is a modified crown reduction gear, comprising: a pressing mechanism 16 operated to rotate; a fixed crown gear 2 fixed to an external member 15; a movable crown gear 1, wherein the difference in the number of teeth between the gears is one; and an output axis 3 flexibly attached to the gear 1. The gear 1 engages with the gear 2 at a slant by pressing-force provided from the mechanism 16. In this instance, contact locations of teeth of the gears 1 and 2 are dispersed at two places existing at both sides between which a gradient center line intervenes.
