Abstract: The device concerns measuring the propagation and bending losses that take place in the individual mode of the multi-mode waveguide. The method applied is a new one comprising butt-couple and prism-couple together with phase-modulation method. Electrodes are made on the waveguide, and applied with voltage. The electro-optical effect is used to modulate the effective length of the waveguide in forming a Fabry-Perot etalon. From here, the contrast of the butt-couple's output and the loss can be measured. At the same time, as the prism-couple is able to separate the multiple modes individually, and measure the contrast and loss of each mode through every output mode which are then compared with the butt-couple, each mode's propagation and bending losses values of the multi-mode waveguide can be derived.

Abstract: A device for unlocking a tubular-type door lock in conjunction with the indoor handle is disclosed. A hollow shaft is fitted into the outdoor plate, while a hollow sleeve is axially received in the hollow shaft to be movable in opposite directions. The sleeve is normally and rotatably positioned in the opening of the outdoor plate to be unlocked, but selectively engages with the locking slot of the outdoor plate to be locked. A ratchet unit, consisting of locking and unlocking ratchets, is received in the sleeve, thus being operable in conjunction with the indoor handle to selectively move the sleeve. The two ratchets, individually having a ratchet face, engage with each other at their ratchet faces to be relatively slidable on their slope surfaces in conjunction with the indoor handle, thus selectively and axially moving the sleeve from the locked to the unlocked position.

Abstract: A method is described for depositing a complex optical multilayer coating on a substrate. The coating consists of multiple layers of at least two material types. The layers are sequentially deposited in a deposition chamber by reactive deposition; preferably sputtering, and the thickness of the deposited layers is determined one or more times during the layer deposition by taking optical measurements of the deposited layer and fitting theoretical values derived from a model of the deposited layers to the corresponding actual values obtained from said measurements. A process variable is continually controlled to ensure homogeneity of the deposited layers so that a valid thickness determination can be made from said theoretical model.
