IPC: B41J2/16
Filed: 1990-05-29
Abstract: PURPOSE:To prevent the occurrence of defective products due to a short circuit between each segment electrode by a method wherein the segment electrodes on a base plate for giving instructions to piezoelectric transducers are so arranged as not to reach the end face of a base plate. CONSTITUTION:Since segment electrodes 12 do not reach the edge of a stamped part 13 of a base plate 8, there is neither occurrence of the burr resulting from the press working of a conductor nor entry of a conductive adhesive agent between the segment electrodes and a base member. Therefore, no short circuit occurs between the base member 10 and the segment member 12. The structural pattern of the conductors on the base plate spaced apart from one another can be achieved by electroless deposition in a plating process.

Abstract: PURPOSE:To adjust an input level automatically in response to audio input signals of levels different from each other coming from a sound source by providing a level variable means corresponding to an output level of plural electronic devices so as to correct an output level difference of the electronic devices in response to the selection of a selector. CONSTITUTION:Analog or digital audio signals from a CD player 1, a DAT player 2, an FM tuner 3 and a cassette deck 4 or the like being plural sound sources are fed to a control amplifier 11 in a control section 6 via a switch S of a selector 5. The control amplifier 11 acts like an electronic volume able to adjust, e.g. the output level of the control amplifier 11 linearly by applying a DC control signal to the amplifier 11. When any of the electronic devices 1-4 being the plural sound sources is selected, the level variable means 11 is automatically adjusted so that the output level of the device reaches a preset level in response to the selection output. Thus, the audio level adjustment is not required in the case of selection of the sound source connected to the selector due to a difference from an input analog signal level depeneing on the source device connected.

IPC: F04D19/04
Filed: 1981-09-04
Abstract: PURPOSE:To reduce loss of rotational energy by a method wherein three freedoms out of five freedoms other than rotation are controlled and bound positively and two freedoms are bound passively. CONSTITUTION:The axial-flow molecular pump is a mechanism by which gas molecules are transferred from the intake port to the exhaust port by high-speed revolution of rotor disk 8-a by a high-frequency motor 10.
