摘要： The present invention relates mainly to a small dielectric antenna capable of obtaining a good VSWR characteristic even if it is placed in the vicinity of a grounding pattern when mounted on a circuit board. A dielectric antenna is formed in which a feed point of an antenna element 13 having a resonance frequency set to a first frequency in a first frequency band and a feed point of an antenna element 14 having a resonance frequency set to a second frequency are connected to an external feed terminal 12b, and an open stub 15 connected to the antenna element 14 in the vicinity of the feed point. The open stub 15 is provided to enable resonance at each of frequencies to be used while the lengths of the antenna elements 13 and 14 are shorter than ordinary lengths determined according to the wavelengths of the frequency to be used. Further, even in the case of placement in the vicinity of a grounding conductor pattern 3 at the time of mounting on a circuit board 1, the frequency bandwidth through which a good VSWR characteristic can be obtained in a used frequency band can be extended.

摘要： A manual breaker for cutting sheet glass. The manual breaker includes a rotational shaft (6) that rotatably holds first and second arms (2) and (4). A sheet glass having a scribe line formed thereon in advance is pinched among rollers (24) and (45). When handles (20) and (40) are actuated to narrow a distance between rollers (24) and (45), the roller (45) moves in a Y-axis direction and an impact shaft (51) impacts the sheet glass, accordingly. The sheet glass can be thereby easily cut into pieces along the scribe line and a sectional quality having a smooth cut surface can be ensured for the sheet glass.

摘要： In a glass cutter wheel where a blade edge is formed on a disk-shaped wheel, grooves having a predetermined shape are formed at a predetermined pitch in a 1/4 or smaller or 3/4 or smaller blade edge line portion of the entire perimeter of the blade edge. The ratio of the groove portion to the entire perimeter, which largely contributes to a scribing characteristic, is changed such that a desired scribing characteristic can be obtained.

摘要： Provided is a manual cutter comprising a holder fitting unit (30) having a holding hole portion (35). A tip holder (10) for the column-shaped manual cutter includes a tip (14) rotatably fitted at its one end, and a positioning attachment part (16) formed by notching the other end. The holder attachment part (30) is caused to fix the tip holder (10) in the holding hole portion (35) by abutting and pushing a fixing screw (38) onto the positioning attachment part (16). As a result, the complicatedness of the tip fitting and replacing works can be eliminated to make the tip proper without any error.

摘要： A piezoelectric element having a crystal structure that enables a piezoelectric film to be formed in an unstressed state is provided. The piezoelectric film contains an a-axis oriented crystal and a c-axis oriented crystal, where a difference in lattice constant between the a-axis oriented crystal and the c-axis oriented crystal is not more than 0.06 Å. The present inventors have newly found that a stress accumulated in the piezoelectric film can be reduced while maintaining favorable piezoelectric properties when a condition that the difference in lattice constant between the a-axis oriented crystal and the c-axis oriented crystal is not more than 0.06 Å is satisfied. When the condition is satisfied, the c-axis oriented crystal and the a-axis oriented crystal are properly balanced and as a result crystal particles of the piezoelectric film are closest-packed on its base in an ideal state, which contributes to a reduced stress.

摘要： A scribe method for a brittle material substrate is a method in which a plurality of scribe lines are formed in directions intersecting with one another in a surface of the brittle material substrate, wherein at least one scribe line in a first direction is formed by a scribe means generating a high-penetration vertical crack in the brittle material substrate by applying impacts of a short period to the point on the surface of the brittle material substrate. After this, at least one scribe line of a second direction in a direction intersecting with the at least one scribe line of the first direction is formed with the scribe means by scribing without producing intersections with the scribe lines of the first direction.

摘要： A cutter wheel for brittle materials includes a disk with two side planes and an outer peripheral portion between the planes. The outer peripheral portion includes two bevel portions and a ridge portion between the bevel portions. The ridge portion has a plurality of peaks aligned along a circumferential line. For example, the ridge portion includes a straight line connecting two adjacent peaks in the plurality of peaks. Alternatively, the ridge portion is a depression between two adjacent peaks in the plurality of peaks, and the depth of the depression is deeper than the straight line connecting the two adjacent peaks. Preferably, the peaks are spaced apart at an equal distance.
