Abstract: An apparatus for sorting objects by color, such as coffee beans, peanuts, beans and other small granular objects. The apparatus includes a means of conveying the objects, uniformly and individually, to the interior of an illuminated analysis chamber that contains one or more sorting channels. Each sorting channel contains at least one lens group connected to photodetectors. The photodetectors are interconnected to electronic circuitry capable of transforming light reflected, transmitted or emitted by the objects into analog electrical signals that are digitized through electrical level detectors. Color analysis of the objects is based on a matrix sorting process that identifies color by comparing the above digitized electrical signals to the contents of a sorting matrix. There is also a matrix apparatus that allows the operator to select, modify, create and display the sorting matriz. There is a means of automatically generating the sorting matrix based on a sampling of electrical signals produced by passing a group of objects with specific color characteristics through the analysis chamber. Microprocessors in a process controller operating on real time are utilized. Adopting the matrix sorting process, this controller classifies objects as acceptable or unacceptable, as well as controlling and supervising all electronic apparatuses linked to the photodetectors. The process controller operates in every sorting channel so as to ensure that article sorting will be based on the matrix process and the sorting matrix.

Abstract: A membrane (14), which is clamped in at its edge (16), has a flat centre field (18) as well as a rolling fold (20) arranged between the latter and its edge (16). Three switches (36, 36', 36") can be actuated by pressure acting on the membrane (14). For transmitting the actuation forces resulting from the pressure on the membrane (14) to coupling points (32, 32', 32") on one of the switches (36, 36', 36") in each case, a support plate (22) is provided. The centre field (18) of the membrane (14) can only be displaced to the edge (16) of the membrane (14) together with the support plate (22). The support plate (22) is supported at the coupling points (32, 32') of two switches (36, 36') so as to be tiltable in such a way that the active area of the membrane (14), defined by the centre field (18) and an adjoining part of the rolling fold (20), shifts towards the other of these two switches when one of these two switches (36, 36') is actuated. In this way it is achieved that these two switches (36, 36') reliably switch in a given order even if their switching pressures differ only slightly from one another. <IMAGE>

Abstract: In the context of the conventional condensation of naphthalene- 1,4,5,8-tetracarboxylic acid with 1,2-diaminobenzene, the napthoylene- bis-benzimidazole isomers formed are obtained together in the cis and transform. In practice, there was the object of shifting the isomer ratio of the mixture obtained, i.e. of increasing the yield of the desired trans product and of reducing the yield of the cis product. At the same time, there was the necessity to develop a preparation process which optimised the yield and improved the waste water situation. 
<??>This object is achieved according to the invention in that the starting compounds are subjected to a precondensation at 60 DEG  to 110 DEG C in aqueous medium using virtually stoichiometric initial amounts and the condensation is then completed in a second step at 130 DEG  to 180 DEG C.

Abstract: Disclosed is a thermal print head (1) in which heating resistance elements (14) are arranged with high density. The thermal print head comprises a head substrate (10), formed of a single-crystal silicon wafer, and a print driver circuit element (3, 4). The print driver circuit element (3, 4), which is formed by doping the head substrate (10) directly with an impurity, is composed of an MOS-FET. A FET used to form the single-crystal silicon substrate (10) has high electrical mobility, and serves to improve the operating speed of the thermal print head (1). Each heating resistance element (14), whose base material is polycrystalline silicon, is adjusted to a predetermined resistance value by being subjected to diffusion of an impurity. The resistance elements (14) are formed on a protuberance (12) which is formed on the head substrate (10). Thus, the portion of an insulating protective film (15) which corresponds to the protuberance (12) projects outward from the rest, thereby ensuring contact with a printing sheet. An earthing diode (16, 17) or laminate structure is used for an earth line of each heating resistance elements (14) so that the resistance element (14) is situated close to a side edge portion of the head substrate (10).

Abstract: In a microwave integrated circuit, a series circuit of an inductive element (6) and a variable capacitance element (7) is inserted between a source of a field effect transistor (5) of an initial stage circuit and ground. The capacitance of the variable capacitance element (7) is controlled by an input signal applied to an external terminal (10) so that an input impedance of the initial stage circuit is properly changed by the input signal applied to the external terminal (10). Thus, it is possible to set a system to an input matching characteristic which has both a noise matching characteristic and a gain matching characteristic which fit to a system specification.
