Title: Three-phase potential transformer
Inventor: KOBAYASHI YASUYUKI
IPC: H01F38/38
Filed: 1983-04-26
Abstract: PURPOSE:To obtain a three-phase potential transformer (PT) of a small type, enabled to reduce the establishment area, and enabled to form a board to accommodate the PT in a small type by a method wherein the respective high-voltage terminals of the adjoining high-voltage lead- out parts of the PTs of two pieces, and the coils of high-voltage windings to face to the respective high-voltage terminals thereof are prevented from application of a voltage between them. CONSTITUTION:When high-voltage terminals V1A, U1B of two pieces are connected by a connecting lead 12, the outer peripheral sides of the respective high-voltage terminals V1A, U1B and coils 8A2, 8B1 are made to have the same electric potential. Therefore, even when the high- voltage lead-out part 3A2 of a PT 1A provided with the high-voltage terminal V1A approaches the surface of a synthetic resin 7B layer at the outside of the coil 8B1 of an adjoining PT 1B, and moreover even when the high-voltage lead-out part 3B1 of the PT 1B provided with the high-voltage terminal U1B approaches the surface of a synthetic resin 7A layer at the outside of the coil 8A2 of the PT 1A on the other side, because no voltage is applied between them, partially electric discharge is not generated in a gap part. Moreover, an interphase voltage is applied between the outer peripheral sides of the coils 8A1, 8A2, and lead-out leads 10A, 10B, while because only the synthetic resins 7A, 7B having high dielectric strength are interposed between them, generation of partially electric discharge at the part thereof is reduced. Accordingly, because a weak point part in regard to insulation is not generated even when the two PTs 1A, 1B are juxtaposed, the establishment area can be reduced.

Abstract: PURPOSE:To execute the sure fixation of a mirror to a holding frame by causing the holding frame to directly hold the mirror with shrinkage at the time of cooling. CONSTITUTION:A mirror 6 inserted into an overhang part 2 of a formed article main body just after a plastic sheet formed of, for example, an acrylonitrile butadien styrene is heat-softened, attracted to a mold by a vacuum force and form-given is formed in a dimension to be accepted in an accepting part J at a void S of the degree of 1mm from the overhang part 2 at the time of inserting.

Title: Annular array ultrasonic diagnostic device
Inventor: TAKAMIZAWA KINYA
IPC: G01N29/04
Filed: 1988-03-26
Abstract: PURPOSE:To enable the high resolution of an ultrasonic image by suppressing the deterioration of a sound field due to the influence of a refraction generated since the sound speeds of a coupling solution and an acoustic window are different from the sound speed of an organism. CONSTITUTION:A delay time control circuit 11 gives a correction to a wave surface shape so that sound waves radiated from all sound sources can be converged in a position P1 separated by an equivalent curvature radius r2 from a recessed surface annular array ultrasonic transducer 2, and sets the delay time of a transmission/reception delay circuit so that a satisfactory convergent beam pattern can be obtained at a converged point. Namely, on a wave surface a (conventional spherical wave surface) before the correction indicated by a broken line, since ultrasonic beams radiated from respective transducers 2a-2e are phase-shifted at an acoustic window 5, a correct convergence can not be executed in the actual converged point. Then, by changing the spherical wave surface [wave surface (a) before the correction] into an S-shaped wave surface [wave surface (b) after the correction] to be indicated by the full line drawn, the influence of the refraction due to the acoustic window 5 can be corrected.
