Title: Polarization-plane independent type light amplifier
Inventor: NIRUZU ANDAASU ORUSON
IPC: H01S5/50
Filed: 1989-06-28
Abstract: PURPOSE: To simplify an optical amplifier device by re-transmitting radiation receiving the rotation of a plane of polarization to an amplifier so that the gains of both modes substantially become equal by permitting TE and TM modes to pass through the amplifier the even number of times. CONSTITUTION: The TE and TM modes passing the amplifier 12 forward in the polarization plane depending-type amplifier 12 of multiplex passage (reciprocal passage, for example) are exchanged each other in a return route. Thus, the TE and TM modes obtain substantially equal gains on average after they pass through the amplifier means 12 for the even number ofo times (twice, for example). Radiation emitted from one end parts 12 and 2 of the amplification means 12 rotates the polarization plane by 90 degrees (or odd times) by making it pass through a polarization plane rotation means before it passes through the amplification means 12. Thus, only one amplifier 12 and one coupler 14 are required.

Title: Ultrasonic probe
Inventor: FUJISHIMA KAZUO
IPC: G01N29/24
Filed: 1990-06-27
Abstract: PURPOSE:To optionally vary the opening angle of the concave surface of an acoustic lens by providing two shield bodies which move in opposite directions at the same time below the lens concave surface of the acoustic lens. CONSTITUTION:When a knob 14 is rotated, a screw rod 13 also rotates and arms 11a and 11b move according to the rotation. If a critical angle matching a replacing body to be inspected is smaller than a critical angle obtained with an opening angle which is used for a last body to be inspected at the time of replacing the body to be inspected with the body to be inspected, an inspecting person rotates the knob 14 anticlockwise to put the shield plates closer to each other and thus decrease the interval (t), thereby varying and setting the opening angle THETAA to an angle where a proper critical angle is obtained. When a larger critical angle is required, on the other hand, the knob 14 is rotated in the reverse direction to increase the interval (t) and the opening angle THETAA is varied to an angle where the proper critical angle is obtained. Consequently, the need to replace the ultrasonic probe before the body to be inspected is replaced is eliminated and the handling is facilitated.
