  • Patent number: 5816144
    Abstract: A precision roll stand includes a roll housing absorbing the rolling forces. In the roll housing rolls constituting a roll pair with their roll chocks are mounted so as to be rotatable and mutually adjustable by an adjustment device which changes the axial distance between the pair of rolls. A drive housing including a roll drive is connectable with the roll housing while establishing a drive connection of the roll drive with the rolls and being removable from the same while undoing the drive connection. In order to produce rolled products exhibiting extremely high measuring accuracies and to be able to exchange the rolls quickly and without difficulty, the roll housing has a frame which is open in the direction of adjustment of the rolls and contains and guides the chocks of the rolls. A crosshead for closing the frame carries the adjustment device designed as a pressure medium cylinder and is rigidly connectable with the frame. The drive housing is supported on the crosshead.

  • Patent number: 5811019
    Abstract: A method for a hole inclined relative to the direction of thickness of a workpiece by light energy. A groove is formed in an energy-concentrated portion of a plate as a workpiece for opening on a major surface of a plate operating as a light energy irradiated surface for forming an irregular surface portion. The light energy is illuminated on this irregular surface portion from the major surface of the plate in an oblique direction relative to the direction of thickness of the plate. The irregular surface portion of the workpiece is formed integrally with the workpiece by injection molding. The irregular surface portion may also be formed by sand-blasting, chemical etching or by an abrasive brush. The light energy is a laser, especially an excimer laser. The workpiece may be formed of an inorganic material, an organic material or a metallic material. The hole of a larger angle of inclination is formed by employing the light energy.

  • Patent number: 5808868
    Abstract: The protective housing (11) of the module IS placed in the manner of a cap on the outer edge (3) of a cooling body (1), on whose heat contact surface (5) facing the protective housing (11) lie the power components (9) or the circuit bearer (6) of a hybrid circuit (8). The protective housing (11) is made of plastic and has integrated clamp and lock areas (12, 13). The outer edge (3) of the cooling body (1) is fashioned so that by placing on of the protective housing (11) an annular positive and frictional connection can be produced between the protective housing (11) and the cooling body (1). The placing on simultaneously effects the surface pressure between the power components (9) and a heat contact surface (5) of the cooling body (1) by means of frictional connection elements (16, 17, 21) arranged between the power components (9) and the protective housing (11).

  • Patent number: 5808533
    Abstract: The modular relay has a base (1) on which a relay system (2, 3, 4) is constructed, as well as a printed circuit board (6) which stands upright on the base. Contact elements (41c, 42c, 43) of the relay are directly connected to flat connectors in the base, via conductor elements. Further conductor elements in the base likewise form flat connectors as connections for a modular circuit which is arranged on the printed circuit board. All conductor elements of the base additionally form solder connecting pins (51b to 56b), which are integrally formed, which all emerge in a row on one side wall of the base, and which are soldered to the printed circuit board in the lower edge region of said printed circuit board. This results in a compact modular structure for a relay having a maximum number of connecting elements, the allocation of these connecting elements being variable for different modular circuits.

  • Patent number: 5803934
    Abstract: Vanadium doping has been found to increase the sinterability of La.sub.x Ca.sub.y CrO.sub.3 (x+y=1) while retaining its high temperature electrical and chemical properties. Specimens of La.sub.x Ca.sub.y CrO.sub.3 with about 2 mol % V were sintered at 1,300.degree. to 1,450.degree. C. for 2 to 8 hours to achieve more than 92% theoretical density, as compared to less than 75% for those specimens not containing V. The electrical conductivity of La.sub.0,76 Ca.sub.0,26 CrO.sub.3 +2 mol % V in 10.sup.-16 and 1 atm of O.sub.2, was measured to be 12 and 30 S/cm, respectively. Preliminary experiments with tape cast laminates and spray coated specimens give indication that La.sub.x Ca.sub.y CrO.sub.3 +V can be sintered on YSZ with good adherence between the two materials.

  • Patent number: 5805744
    Abstract: Even when manufacturing of a waveguide is fluctuated and an optical parameter is fluctuated or a wavelength of emitted light is fluctuated, a phase difference between two intrinsic modes can be compensated (positive integral multiple of .pi.). Thus, it is possible to prevent a reproduced signal from being deteriorated by elliptically polarized light. A magneto-optical reproducing pickup includes an optical waveguide (4) for guiding light reflected on a magneto-optical recording medium to a differential photo-detecting unit (9) side and phase compensating circuitry for compensating a phase difference between light components of a TE mode an a TM mode included in reflected light.
