摘要： The invention is to provide a multi-beam light source where the interval of core portions is reduced and the core portions are arranged on a straight line. The multi-beam light source includes a first substrate where a plurality of optical fibers each having a core portion and a clad portion surrounding the core portion coaxially are fixed at predetermined intervals, and a second substrate where a plurality of similar optical fibers are fixed at predetermined intervals. The first and second substrates are put and bonded on top of each other so that the core portion of each optical fiber on the second substrate is inserted between core portions of adjacent optical fibers on the first substrate, and the core portions of the optical fibers on the first and second substrate are arranged substantially on a straight line.

摘要： Print hammers in a printing head of a dot line printer for printing with an ink ribbon multiple dot lines in a single shuttling direction and for providing a character line by the combination of the multiple dot lines in accordance with reciprocal motions of the print head while feeding a printing sheet in a line to line direction include hammer springs and printing pins provided at the free tip end portions of the springs. The printing pins are positioned offset from one another in the shuttling direction to thus perform multiple dot line printings in the single shuttling motion. Each of the printing pins has a printing pin surface in abutment with the printing sheet through the ink ribbon. The printing pin surface has a polygonal shape defined by a combination of ridge lines. All ridge lines extend obliquely with respect to the shuttling direction for facilitating grinding of the printing pins.

摘要： An ink jet print head includes pressure chambers, a diaphragm forming a side of the pressure chambers, stacked piezoelectric elements, a piezoelectric element fixing plate, and a housing. The stacked piezoelectric elements are attached to the diaphragm in a one-to-one correspondence with pressure chambers. The piezoelectric element fixing plate is fixedly attached to and supports the stacked piezoelectric elements. The housing includes a common ink channel portion that supplies ink to the pressure chambers. The piezoelectric element fixing plate and the stacked piezoelectric elements are disposed at least partially in the space defined by the diaphragm and internal side walls of the ink channel portion with a gap existing between the piezoelectric element fixing plate and the internal side walls.

摘要： An on-demand ink jet head includes a plurality of piezoelectric elements in alignment with one another with one end of each facing in the same direction. The end of each piezoelectric element is bonded by an adhesive material to a diaphragm which, together with a nozzle plate, forms a pressurizing chamber. To confine the fluid state adhesive material expelled out of the endmost piezoelectric elements, a dummy piezoelectric element is disposed outside each endmost piezoelectric element. The adhesive material, when dried, serves as a damper of the piezoelectric element for damping unwanted vibrations of the piezoelectric elements. By the provision of the dummy piezoelectric elements, the distribution of the adhesive material becomes substantially even between the piezoelectric elements, resulting in uniform operations of the piezoelectric elements.

摘要： A method of and apparatus for fabricating an article having an aspheric figure, wherein the three-dimensional positional relationship between a work and a grinding spindle as a processing tool is controlled in terms of a polar coordinate system. The grinding spindle extends in a plane which is perpendicular to the direction of rotation of said work and is made to swing along an arcuate path. The distance between the axis of rotation of the work and the axis of the swing of the grinding spindle is changed in relation to the rotational angular position of the work.
