    摘要： It is a main object of the present invention to provide an oil ring which is capable of reducing sliding friction even in a high speed revolution region of a piston, and capable of reducing the consumption of oil. To achieve the object, the present invention provides an oil ring which is formed into cross-section substantially of an I-shape that two rails are connected at a columnar portion thereof, wherein a sliding projection formed in each of the two rails comprises an outer side surface of sliding projection which forms an outer portion of the sliding projection, a inner side surface of sliding projection which forms an inner portion of the sliding projection, and a sliding surface which slides on a cylinder inner wall and forms a tip end of the sliding projection; wherein a taper angle of the outer side surface of sliding projection is in a range of 10° to 60°; and wherein the outer edge portion, where the outer side surface of sliding projection and the sliding surface are joined to each other, is formed into the curved surface, and the sliding surface has the curved surface sliding portion which is joined to the outer side surface of sliding projection and formed into a gently curved surface.

    摘要： A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements arranged at regular intervals and fixed at their one ends to a base, the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures, the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30 V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element and the nozzle aperture is discharged to the outside as an ink drop. Because the driving voltage required for forming an ink drop is as low as possible, it is possible to simplify a driving circuit, and because of cutting a piezoelectric plate, it is possible to form small-sized piezoelectric elements with the same accuracy as in a process of producing a semiconductor.

    摘要： A method of manufacturing an inkjet recording head including drive electrodes arrayed at fixed pitches on the surface of an elastic plate, a common lead-out electrode lead from a common electrode formed on the surface of the elastic plate, the common lead-out electrode being arrayed extending in the direction of the arrays of the drive electrodes, while being spaced a fixed distance from the drive electrodes, the ends of the common lead-out electrode being connected to external, and piezoelectric vibration plates of which the reverse sides are in contact with the drive electrodes, and to the first ends are continuous, covering the common lead-out electrode. No disconnection is formed in the area of the piezoelectric vibration plates where the two groups of the piezoelectric vibration plates face, thereby ensuring a reliable bonding of the piezoelectric vibration plates and the elastic plate.
