An endocavity ultrasonic probe (2) includes a backing member (4) of cylindrical or convex shape, and a plurality of strip shaped ultrasonic transducers (5) arranged on the backing member. The ultrasonic transducer is composed of three piezoelectric layers (10), electrode layers (11a, 11b) formed above and below each piezoelectric layer, insulating films (12) formed at one side face of each electrode layer, and side electrodes (13a, 13b) formed along both side faces of the piezoelectric layers and the electrode layers. The electrode layers are electrically connected to one of the side electrodes but insulated from the other side electrode. Two vertically adjacent electrode layers are electrically connected to a different one of the side electrodes.

A method of producing fine-particles of an organic pigment, comprising: the step (A), allowing an organic pigment solution in which an organic pigment is dissolved in an aqueous medium containing at least one dispersing agent, and a solution for adjusting the pH of the organic pigment solution, to flow and contact with each other, in a laminar flow state in a channel (flow passage), wherein a hydrogen ion exponent (pH) of the organic pigment solution is changed in the channel flow; and the step (B), employing, in combination with said (A), at least one controlling means selected from the group consisting of (a1) controlling the ratio between flow rates of the solutions, (b1) changing the molecular weight of a polymer dispersing agent to be contained in the organic pigment solution, (c1) controlling the content of the dispersing agent, and (d1) controlling the temperature during the contacting and flowing, thereby to form fine particles of said organic pigment of a desired particle size.
摘要:
In the production of a laminate (127) by nipping a support (124) and a resin film (112) of a thermoplastic resin by means of a nip roller (118) and a cooling roller (116) while coating the resin film (112) onto the surface of the support (124), the accompanying air following the rotation of the cooling roller (116) to the nip point (P) is shut off by blowing a gas permeable through the resin film from a gas jet nozzle (126) toward the surface of the cooling roller (116). Thereby, the occurrence of craters can be inhibited, a laminate excellent in surface appearance can be produced and the production of a laminate effective especially at the time of a line speed rise in the laminate production is performable.
