Abstract:
The invention relates to a transducer laminate in which electrical contact is made between electrical conductors (C1, C2) and a transducer layer (TY). The transducer laminate includes two adhesive-coated foils (F1, F2), whose adhesive coatings (AC1, AC2) are arranged to face each other. At a first position (A-A′) along the length of the two electrical conductors (C1, C2) the two electrical conductors (C1, C2) are sandwiched between the adhesive coatings (AC1, AC2) of the two adhesive-coated foils, and the transducer layer (TY) is also sandwiched between the two electrical conductors (C1, C2) such that electrical contact is made with the electrodes (E1, E2) on the transducer layer (TY). At a second position (B-B′) along the length of the two electrical conductors (C1, C2) the two electrical conductors (C1, C2) are sandwiched between the adhesive coatings (AC1, AC2) of the two adhesive-coated foils and there is no transducer layer (TY) sandwiched between the two electrical conductors (C1, C2).
Abstract:
The invention relates to a transfer stack (TS) for transferring a portion of a foil within a perimeter (P) that includes a transducer (T) to an article (A) such as a medical device or a medical needle. The transfer stack includes a carrier substrate (CS), a foil (F) having a transducer (T) incorporated therein, and the transducer is laterally surrounded by a perimeter (P). The foil (F) is separable from the carrier substrate (CS) by overcoming a first peel retaining force (PRF1). An adhesive layer (AL) is also attached to the foil. The adhesive layer (AL) is configured to provide adhesion between the foil (F) and an article (A) such that when the article (A) is attached to the foil via the adhesive layer (AL) the foil (F) is separable from the surface of the article (A) by overcoming a second peel retaining force (PRF2). The second peel retaining force (PRF2) is greater than the first peel retaining force (PRF1).
Abstract:
A mounting structure includes a first substrate which has a first surface on which a functional element is provided, a second substrate that has a second surface facing the first surface, a wiring portion that is provided at a position which is different from a position of the functional element on the first surface, has a third surface facing the second surface, and is electrically connected to the functional element, and a conduction portion that is provided on the second surface, protrudes toward the first surface, and is connected to the third surface so as to be electrically connected to the functional element, in which an area of the third surface is larger than an area of a first end section of the wiring portion on the first substrate side in a plan view which is viewed from a thickness direction of the first substrate and the second substrate.
Abstract:
An ultrasonic transducer array, and a method for manufacturing it, having a plurality of transducer elements aligned along an array axis in an imaging plane. Each transducer element includes a piezoelectric layer and one or more acoustic matching layers. The piezoelectric layer has a concave front surface overlayed by a front electrode and a rear surface overlayed by a rear electrode. The shape of each transducer element is selected such that it is mechanically focused into the imaging plane. A backing support holds the plurality of transducer elements in a predetermined relationship along the array axis such that each element is mechanically focused in the imaging plane.
Abstract:
A method for preparation of a biaxially stretched polyester film with good slip and release properties comprising coating an acrylic resin-based aqueous resin compound, which is derived from adding an amino-modified silicone compound having the structural formula (1), a waxy additive and inert inorganic particles to an acrylic resin, on at least one surface of a mono-axially stretched polyester film, drying the polyester film coated with the aqueous resin compound, mono-axially stretching the dried polyester film in a direction perpendicular to that of the previous mono-axial stretching and heat-treating the stretched polyester film: ##STR1## wherein R' is a hydroxyl group, a methyl or an ethyl; R" is a hydrogen carbide which has 0 to 10 carbon atoms and to which NH or NH.sub.2 is bonded; m is an integer in the range of 5 to 1,000; n is an integer in the range of 100 to 20,000; and n/(m+n)=0.5.
