    摘要: A piezoelectric transformer is described that features high energy-conversion efficiency and high reliability. Four driver piezoelectric ceramic plates are provided on the upper and lower surfaces at both ends of a generator piezoelectric ceramic plate having a rectangular shape, the driver piezoelectric ceramic plates having the same width and one-third the length of the generator piezoelectric ceramic plate. Vibration is not hindered and the energy-conversion efficiency is therefore increased in this construction because the draw-out positions of the four input electrodes and three output electrodes are all positioned at the nodes of mechanical vibration. In addition, the reliability of lead wire connections is improved because vibration places no load on the lead wires. Finally, input capacitance and step-up capabilities can be raised by adopting a multilayer construction for the driver piezoelectric ceramic plates.

    摘要: A piezoelectric transformer element includes a piezoelectric plate made of a ceramic material, and input and output electrodes formed on the piezoelectric plate, and outputs a voltage from the output electrode upon application of a voltage to the input electrode. A reinforcing layer is selectively disposed on that portion of the piezoelectric plate where tensile stress concentrates when the piezoelectric transformer element is driven. The reinforcing layer is made of a material having the same composition as that of the ceramic material forming the piezoelectric plate and a particle size, after sintering, smaller than that of the ceramic material. A method of manufacturing a piezoelectric transformer element includes the steps of selectively disposing a reinforcing layer made of a ceramic powder at a required portion of each of ceramic sheets that form a piezoelectric plate of the piezoelectric transformer element, and molding and sintering the ceramic sheets and the ceramic powder, thus fabricating the piezoelectric plate. The ceramic powder has the same composition as that of the ceramic sheets of the piezoelectric plate and a specific powder surface area larger than that of the piezoelectric plate.

    摘要: A stacked piezoelectric transformer is formed by stacking piezoelectric ceramic sheets each formed with internal electrodes at their predetermined regions, and has portions formed with the internal electrodes as input portions, and a portion not formed with the internal electrodes as an output portion. Ceramic layers, which are formed by mixing a small amount of metal powder to a ceramic powder made of the same material as that of the piezoelectric ceramic sheets, are formed among layers of the output portion. A method of manufacturing a stacked piezoelectric transformer includes the steps of forming an internal electrode at a predetermined region of a piezoelectric ceramic sheet, forming a ceramic material at the remaining region of the piezoelectric ceramic sheet, and stacking a plurality of piezoelectric ceramic sheets each obtained in this manner. The ceramic material is obtained by mixing a small amount of metal powder to a ceramic powder made of the same material as that of the piezoelectric ceramic sheet, and is formed to have the same thickness as that of the internal electrode.

    摘要: A battery pack is provided which can be suitably used in a case where charging of a dedicated secondary battery in a portable terminal device is difficult. The battery pack is mounted in a battery mounting section in a portable cellular phone (portable terminal device) proper. In the battery pack, alkaline accumulators are connected in series. Alkaline accumulators generate electromotive forces having a voltage (3V) being lower than that of the dedicated secondary battery. A power source circuit has a boosting-type DC/DC converter which boosts a voltage of the alkaline accumulators being connected in series at a level being same as that of the dedicated secondary battery (for example, 4.5V), and outputs the boosted voltage. An electrical double layer capacitor has a capacity to feed stable power to an internal circuit in which power consumption increases or decreases in a burst manner and is charged by application of an output of the power source circuit and stores the power.

    摘要: An external cathode terminal (16) is adhered to one surface of a capacitor element while a prepreg (25) is adhered to another surface of the capacitor element. A reinforcement plate (26) is adhered to the prepreg. Heat and pressure are applied to the external cathode terminal, the prepreg, and the reinforcement plate to elute thermosetting resin from the prepreg in the side of the capacitor element, thereby sealing the side of the capacitor element with eluted material (27A, 27B). Inasmuch as transfer molding is not used as exterior package, the element never deforms by injection pressure of resin. It is possible to thin by a thickness of exterior package resin. Inasmuch as eluted thermosetting resin does not include a mold release agent, it has good adhesion for the external cathode terminal.
