Abstract: The object is to improve a test container for checking apparatuses for measuring and detecting gases which contains a test substance atmosphere which contains a specified concentration of test substance and into which the measuring head of the apparatus for measuring gases can be introduced, in such a way that it is possible to provide in the container over a prolonged period of time a test substance atmosphere which is such that its composition does not change substantially and which does not have to be prepared immediately before carrying out the check. The container should be easy to manufacture, be of low weight, easy to handle and convenient to transport and store. For this purpose a liquid (7) which is composed of a solution of the test substance in a solvent which does not affect the measuring head in such a quantity and concentration that the vapour of the test substance is saturated is introduced into the test container (1) which is sealed in a gastight manner by a pierceable seal (5).

Abstract: A relay for wideband signals is provided having a rotor which includes a permanent magnet structure, an armature, and a microstrip pattern for selectively engaging microstrip patterns on a substrate and having a stator which includes an electromagnet. To minimize wear, while maintaining high frequency performance, the rotor is raised, rotated, and lowered by a stator or electromagnet onto the new position relative to the substrate microstrip pattern. In a first stable state the electromagnet is inactive and the rotor engages the substrate microstrip pattern in a first position. To place the relay in a second stable state, the electromagnet is energized which simultaneously attracts the armature, raising the rotor, as well as repulsing the permanent magnet structure. The rotor then rotates to the desired second position and the electromagnet is inactivated. The rotor then lowers and engages the substrate microstrip pattern in a second position.

Abstract: A modular compiler (120) is used to compile code for execution by an agent engine (108) and a plurality of application programs (100). The modular compiler (120) includes a class independent parser (122) which parses program code which is to be executed by the agent engine (108). The modular compiler (120) also includes a class dependent parser (123,124,167,168) for each application program (100). Each class dependent parser (123,124,167,168) parses program code which is to be executed by its respective application program (100). When an application program (100) is added to the computing system, an associated class dependent parser (123,124,167,168) is added to the modular compiler (120). When an application program (100) is removed from the computing system, the associated class dependent parser (123,124,167,168) is removed from the modular compiler (120).

Abstract: The present invention relates to a method to binarize multivalued image with variable density. 
     As the method for binarization, ordered dither method and error diffusion method are known, whereas satisfactory reproduction of the image is not always achieved in case of color image. 
     According to this invention, input signal from the input pixel is binarized by threshold. The error between the input signal and the threshold is divided at the predetermined co­efficient ratio and is accumulated and added to input signal from the subsequent input pixels, and the predetermined ratio is determined in proportion to the coefficient of the element of partical matrix fixedly corresponding to the input value matrix. 
     By performing this procedure on all pixels of the color image through scanning, binary value image of monochromatic image of the color image can be obtained. In case the monochro­matic image to be superimposed is reproduced for each color, coefficient matrix is rotated at different angle for each color, and the above processing is performed.

Abstract: A detrack detecting system for detecting deviation of the beam spot from the track in an optical recording/­reproducing apparatus in which recording and reproducing of data are performed by irradiating optical beams onto an optical disc. Three beam spots are irradiated at positions on the optical disc which are shifted from each other by a predetermined distance laterally of the track. The reflected lights are respectively detected by three photodetectors whose photosensitive surfaces are divided into two parts and tracking error signals are detected by a push-pull system. A tracking error signal obtained from the centre beam spot of the three beam spots and tracking error signals obtained from other two beam spots are respectively added to obtain the first and second composite tracking error signals. Detracking state is detected based on the polarities of the first and second composite tracking error signals.

Abstract: A method for forming a field oxide structure in an integrated circuit is disclosed. The resulting structure exhibits minimal bird's beak formation and has dimensions smaller than what can be achieved by straightforward lithography. The process includes formation of a pad oxide (e.g., 13) and an overlying silicon nitride layer (e.g., 27) (an optional polysilicon stress buffer layer (e.g., 15) may be sandwiched between the oxide and nitride.) An opening is lithographically created in the oxide/ nitride stack. Then the oxide is wet etched to create a small gap underneath the overlying nitride. Next a nitride spacer (e.g., 29) is formed within the opening. The spacer has a foot-like protrusion (e.g., 27) into the gap. Then a field oxide (e.g., 29) is grown within the opening defined by the spacer.
