A method is provided for making an integrated optics device having a substrate (12) formed of lithium niobate and having an optical waveguide (15) defined within the substrate. A slot (14), having a distal end wall exposing an end face (23) of the waveguide, is micromachined into the surface of the substrate by exposing the surface to a beam of light having an intensity and wavelength selected to ...

An X-ray diagnostic apparatus is to be provided which permits the taking of X-rays on the bed, without its being necessary to lift the patient in order to push an X-ray film cassette (9a) underneath. The intention is that the X-ray film cassette (9a) should be simply and accurately centred relative to the X-ray source (13). The bed has two supporting surfaces (1, 4), of which the upper one ca...

The utility model relates to a mechanical linkage system installed on a small size wind power electric generator, which aims to solve the defect that an existing small size wind power electric generator can not generate electricity when wind doesn't exist or only gentle wind exists. A crank shaft is arranged on the wheel shaft hub of a wind power machine, and a ball shaft sleeve is installed on th...

The utility model relates to a semi-tight lead-acid accumulator of an adsorption type for motorcycles. A layer of spacing mould that can avoid dendrite short circuit and the penetration and oxidization of partition boards is wrapped outside a positive plate. The partition boards adopt adsorbing insulation materials of high imbibition capacity and wrap every bottom of the positive and the negative ...

The invention relates to a cylindrical winding tube (1) made of cardboard, wound layers of paper or plastic, on which chemical yarns are wound to form cross-wound bobbins. Such a bobbin tube possesses in a normal plane, in the vicinity of one end face, a yarn-catching slit (2) which extends over some of the circumference and which consists of a drop-in piece (4) and of a clamping piece (5). To cat...

At the front and at the rear the ski binding has in each case a jaw which can be swivelled at least about the z-axis. The two jaws are connected to a control member (5). With known elasticity of the two jaws, the control member can establish on the basis of its movement (rotation/translation) whether the external loading is pure torsion (rotation only) or transverse force torsion (rotation with tr...

A boot-holder (4), which is pivotable about a vertical axis (3), is forced by means of a piston (11) into the normal position illustrated. At its end facing the boot-holder (4), the piston (11) is arranged so as to be displaceable with play in the transverse direction and at its other end virtually without play in a guide (6). Pivoting movements of the boot-holder (4) can thus take place to the gr...

For each test element being tested in a clinical analyzer, there is a corresponding calibration curve. However, the calibration curve is defined by an equation having calibration coefficients which must be imparted to the analyzer so that the appropriate results can be calculated from the measurements taken off the test element. One way of imparting the calibration coefficients is to supply them i...
