Abstract: The pattern design, grading and marking optimiz­ing system for garment industries is featured by the fact that the first module digitizer comprises a table includ­ing a two-dimension grating, and a locating device con­sisting of a pencil-like body to generate a magnetic field the intensity of which is picked-up at the grating junc­tion, the table being provided with a digitizing menu com­prising a plurality of icons adapted to be selected by means of the locating pencil, each said icons correspond­ing to program options permitting to progressively define an outline on the computer console of the first module. 
     The use of the icon menu allows to dispense with the creation of a special keyboard each of whose keys rep­resents a particular graphic option, besides the digit­izer, to create and move two-dimension patterns. This provides a cost improvement and a technical simplification enhancing the system reliability and increases the system ergonomics.

The final structure comprises polysilicon features (36) flanked by either oxide isolation or additional polysilicon features and is planar without requiring a planarization etchback. The process is applicable to polysilicon electrodes over active areas as well as polysilicon resistors over isolation oxide.

Abstract: To measure the torque of a rotating twist cylindrical body, the torque sensor device on the body contains two spaced-apart arrangements of magnetic-field-generating elements. These two arrangements are in each case associated with stationary magnetic-field sensors (3, 3'). Electronics are used for measuring the phase shift of the voltage pulses caused in the respective magnetic field sensors (3, 3') by the two magnetic-field-generating arrangements. Each magnetic-field sensor (3, 3') contains a compound element (6) of two strip-shaped ferromagnetic element parts with uniaxial magnetic anisotropy and with different coercive field strengths, enclosed by a coil winding (7). In this arrangement a spontaneous remagnetisation is to be produced only in the element parts of the compound elements (6) having the lower coercive field strength by means of an external magnetic switching field of the magnetic-field-generating elements. Electronics are then used for measuring the phase shift of the voltage pulses caused in the respective magnetic-field sensors at the two arrangements. The magnetic-field sensors (3, 3') associated with each magnetic-field-generating arrangement should in each case form an array (2). They are produced as thin-film structures on a carrier (4). <IMAGE>

Abstract: An optical waveguide light redirecting arrangement includes an optical waveguide having a solid portion that guides light in a first path along a longitudinal axis, with at least one grating region being embedded in the solid portion at a location remote from its end portions. The grating region includes a multitude of grating elements extending at such longitudinal spacings and at such oblique angles relative to the longitudinal axis to redirect light reaching the grating elements between the first path and at least one second path extending externally of the waveguide and diverging between a focus situated at a predetermined distance from the waveguide and the grating region. When light is directed in one of the first and second paths toward the grating region, it is redirected by the grating elements into the respectively other of the second and first paths with attendant in-phase combination in the other path of light having a wavelength within a range around a central wavelength. The grating elements are formed in the waveguide by exposing the waveguide to an interference pattern of two ultraviolet radiation beams that are symmetrical with respect to a plane extending at the oblique angle relative to the waveguide axis at the center of the grating region.

Abstract: A semiconductor-controlled rectifier provides an example of a semiconductor device having enhanced resistance to electrical breakdown upon application of high voltage in the forward blocking mode. Enhanced breakdown voltage is achieved by having field shaping regions such as buried layers (11,16,19) or one or more bands (29) of relatively heavier doped semiconductor material within a lighter doped region (21) between the electrical connections (12,17) to the device. Such field shaping regions (11,16,19,29) provide termination of the electric field away from the location where electrical breakdown may commence, by shaping the electric field or the depletion region adjacent to the semiconductor junctions.

Abstract: The disclosed system and method authorises a process running at a client data processing system to have access to a service at a server data processing system. The data processing systems are connected by a communication link in a distributed processing environment. A set of credentials for the process are created at the server in response to a message from the client requesting a service. The server returns a credentials id identifying the created set of credentials to the client process. The client uses this returned id in subsequent requests and is authorised access as controlled by the set of credentials identified by the returned id in the subsequent request. The server can deny access to the service by the process if the id returned in a subsequent request is determined by the server not to identify the set of credentials. The server denies the access if the server requires an authentication of the process.

Abstract: A simple reliable process for decaffeination with a high degree of decaffeination is created, in which denaturation of the green coffee is avoided. In this process, the green coffee moistened to a high water content of 35 to 50% by weight is held for some minutes to some hours at a temperature of 20 to 80 DEG C under a gas atmosphere of 75 to 300 bar and, if necessary, is stirred during this. The pressure is then reduced abruptly or within a few minutes with avoidance of freezing to pc >/= p >/= 1 bar (pc = the critical pressure of the gas used). The green coffee is washed with the supercritical gas to give selective extraction of the caffeine and, if required, the process is repeated several times. The green coffee is then predried in a centrifuge and roasted.
