Title: Ultrasonic washing method
Inventor: MIZOKOSHI KAZUHIKO
IPC: H01J9/18
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic washing method capable of eliminating washing unevenness due to standing waves of ultrasonic waves. SOLUTION: A grid electrode part 100B of an electron gun 100 is immersed in pure water 200 stored in a storage tank 210 to carry out ultrasonic washing. An ultrasonic oscillator 300 is installed in the bottom part of the storage tank 210 and generates ultrasonic waves with three frequencies (28 kHz, 45 kHz, and 100 kHz). Moreover, the electron gun 100 is swung in the vertical direction (the direction vertical to the liquid surface) or in the transverse direction (the direction parallel to the liquid surface) by a swinging mechanism through a chuck mechanism 400. Due to the swinging, the washing position by the standing waves of the ultrasonic waves to the electron gun 100 is shifted and also a turbulent current is caused in the surrounding of the electron gun 100, so that the cavitation degree is increased and washing by standing waves can evenly be carried out.

Title: Optical switch and optical switching method
Inventor: OZAWA KAZUMASA
IPC: G01J1/02
Filed: 1992-12-28
Abstract: PURPOSE:To improve the precision of alignment in an optical switch which aligns a 1st and a 2nd light guide with each other by using sensing light and optically couples them without contacting. CONSTITUTION:This optical switch emits the sensing light from a sensing light source 15, propagates it in a tester-side optical fiber 12, and makes the light incident on a non-test optical fiber 7. This sensing light after being branched by an optical coupler 5 is emitted from a branch optical fiber 8 and its quantity is detected by a photodetector 16. The quantity of the sensing light becomes maximum when the optical axes of the optical fibers 7 and 12 are aligned with each other, so a controller 18 finely adjusts the relative positions of the optical fibers 7 and 12 basing on the signal from the photodetector 16 so that the quantity of the sensing light becomes maximum. In this constitution, the sensing light is hardly attenuated, so the detection result which is always stable is obtained.

IPC: F16C33/34
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a roller bearing which can accomplish a long service life, by absorbing an edge load corresponding to a moment load, without rising a processing cost, and without generating a fatigue failure.
