摘要： Green sheets of ceramic are stacked and sintered, to form a pressure-generating-chamber forming member 7 which forms pressure generating chambers 4 with its one surface sealed with an elastic board 2, a flow path regulating board 61 which has flow path regulating holes 60 which apply flow path resistance to ink supplying paths connected to the pressure generating chambers 4, and a common-ink-chamber forming board 18 which has a common ink chamber 19 which is communicated through the flow path regulating holes 60 with the pressure generating chambers 4 which are joined together with no adhesive layer, thus providing a flow path forming member. A green sheet of piezoelectric material is laid on the surface of the elastic board 2, and sintered, to form piezo-electric vibrating plates 3 thereon. The flow path forming member is great in mechanical strength, and is prevented from being bent by the contraction which may occurs when the piezo-electric material is sintered. In addition, the through-holes in the components of the flow path forming member can be corrected in position or in configuration when they are in the form of green sheets.

摘要： Disclosed are a semiconductor device of which a block having a plurality of portions that operate based on a plurality of clocks can be designed and inspected easily, and a method of designing the semiconductor device. First and second clocks whose frequencies are mutually different are used to generate an enabling signal that is validated only during a short period including a transition edge of the second clock. The enabling signal and first clock are supplied to the second portion. The second portion synthesizes the enabling signal and first clock to substantially generate the second clock. Thus, the second portion is regarded as a portion that operates synchronously with the first clock.

摘要： A method of inspecting a crack in a ceramic substrate that is not exposed on the surface. The method can detect all cracks and make objective judgement possible by expressing the inspection result as numerical data. Conductors are disposed on both faces of a ceramic substrate, wherein one of the conductors is a conductive liquid; the insulation resistance value or an electric property dependent on the insulation resistance is measured with the conductive liquid or other conductors electrically connected to the conductive liquid which are used as electrodes.

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 and 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： An ink jet recording head formed by laminating and fixing: a flow path forming plate having through holes for defining pressure producing chambers, ink supply inlets, and a common ink chamber, a nozzle plate having nozzle openings communicating with the pressure producing chambers, and a vibration plate having diaphragm portions that are resiliently deformed in response to displacement of piezoelectric vibration elements one upon another with an adhesive so as to be watertight. The vibration plate has frame-like thick wall portions that extend as far as to the ink supply inlet side of the pressure producing chamber as well as to the inner side of the nozzle opening, and portions closer to a piezoelectric vibration element than to both ends of the pressure producing chamber are made to be supported by a base. As a result of this construction, a nonsupported region of the pressure producing chamber can be shortened, which in turn improves the rigidity of a substrate unit as a whole.

摘要： A signal electrode drive circuit for driving a liquid crystal display panel includes a latch circuit for latching a digitized video signal, a buffer, a graduation signal-forming circuit, an intensity modulation pulse-generating circuit, and an analog multiplexer. The latch circuit holds the video data only once during one horizontal scanning period until a next latch pulse M is generated, thus considerably reducing current dissipation.
