摘要:The vibration seat 20 comprises a seat body 22, a laminated sitting portion 24 supported at its periphery by the seat body such that the sitting portion 24 is free to vibrate relative to the seat body 22. The vibrator 4 is connected to the sitting portion 24 at a single node 1 and it too is free to move relative to the seat body 22. Structural details of the laminated sitting portion are described in relation to figure 2 and include an aluminium textured actuator plate 7, stainless steel upper and lower spreader plates 2, 3 and foam layers 6, 7.

摘要:An acoustic imaging system includes multiple acoustic transducers disposed to circumscribe a portion of imaging surface. An acoustic imaging system also includes a controller and an image resolver. The acoustic transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals. The controller is adapted to apply an electrical signal to the acoustic transducers which, in response, induce a mechanical wave, such as a surface wave, into the circumscribed portion. The controller is also adapted to receive electrical signals from the acoustic transducers. The image resolver uses the electrical signals received by the controller in order to construct an image of an object in physical contact with the imaging surface.

摘要:PURPOSE:To eliminate spurious radiation and to increase the resolution of an ultrasonic wave diagnostic device, by constituting an array type ultrasonic wave probe given with the piezoelectricity only for the piezoelectric ceramic plate located at the lower part of surface electrode. CONSTITUTION:Conductive layers 12-14 are vapor-deposited on both sides of a piezoelectric ceramic plate 11 such as PZT not polarized and on at least one side surface. Photo resist is coated on a surface conductive layer 13 to form surface electrodes 131-13n and folding electrode 141 through processing such as exposure and development. A lead 15 is connected to the electrode 141 and leads 161-16n are connected to electrodes 131-13n, and a lead 17 is located. Thereafter, the piezoelectric ceramic plate 11 is immersed in heated oil, a specified DC voltage is applied to a terminal 18 to give polarized processing to the piezoelectric ceramic plate 11. Thus, regions given with stripe piezoelectricity as shown in hatching can be formed.

摘要:PURPOSE:To change the oscillation frequency in an oscillation driving part in follow up to the temp. deviation in a mechanical resonance point by providing a temp. characteristic compensator and compensating the change with the temp. in a series resonance part. CONSTITUTION:A self-oscillation system is formed of an inductor 17, a series resonance part consisting essentially of an equiv. capacity component of an atomizer, and an amplifier 18, and a capacitor 20 as a temp. compensator compensates the change with the temp. in the series resonance part. Then the oscillation frequency in the oscillation driving part is changed in follow up to the deviation in the temp. of the mechanical resonance point operating efficiently as an atomizer.

摘要:A taut armature reciprocating impulse transducer (100) includes an electromagnetic driver (24, 26) which effects an alternating electromagnetic field in response to an input signal. An armature (12) includes an upper planar suspension member (14) formed by a first pair of non-linear spring members arranged along a first radial axis (50), and a lower planar suspension member (16) formed by a second pair of non-linear spring members arranged along a second radial axis (52) which is substantially perpendicular to the first radial axis (50). The upper and lower planar suspensions members are coupled to the electromagnetic driver (24, 26) and suspend a magnetic motional mass (18) therebetween. The alternating electromagnetic field alternately moves the magnetic motional mass (18), the movement being transformed through the upper and lower planar suspension members (14, 16) and the electromagnetic driver (24, 26) into motional energy.

摘要:PURPOSE:To prevent erroneous operation by elastically energizing a vibration element by an energizing means so as to allow a head part to protrude to the outside of a case and arranging a contact probe for applying driving voltage to a piezoelectric vibrator in opposed relation to the upper surface electrode of the piezoelectric vibrator and covering the surface of the upper surface electrode with conductive rubber. CONSTITUTION:Unless a head part 1 is pushed in a case 6, the upper surface electrode of a piezoelectric vibrator 3 comes into contact with a contact probe 14 and a state such that vibration is generated in the piezoelectric vibrator is not obtained. Therefore, no vibration is outputted from the head part 1 and, as a result, three is no inconvenience such that coordinates data is taken in by mistake due to mere placing of an input pen for a digitaizer on a propagation medium 16 carelessly. When the head part 1 is pressed to the propagation medium 16, for example, when the writing pressure of the head part 1 reaches a predetermined value, a vibration element 4 is pushed in the case 6 against the elastic force of an energizing means 7 and the upper surface electrode comes into contact with the contact probe 14 and the vibration generated in the piezoelectric vibrator is outputted from the head part.
