Abstract: The invention presents a liquid crystal display device (1) characterized by forming pixel portions (15) of transparent electrodes (5), (6) in part of the confronting surface of a pair of light-transmissive substrates, (2), (3) forming orientation films (10), (11) on the pixel portions (15) and non-pixel portions (14) in the remaining surface of the light-transmissive substrates (2), (3) by way of insulation films, (7), (8), (9) and filling the gap of the light-­transmissive substrates (2), (3) with liquid crystal, (4) wherein 
at least on one of the light-transmissive substrates, (2), (3) insulation films (7), (8), (9) of different materials are formed in the pixel portions (15) and non-pixel portions (14), or the insulation film (7) is formed only in the pixel portions (15). According to the invention, therefore, the asymmetricity of liquid crystal molecular orientation is weak in the pixel portions (15), and a bistable memory effect may be obtained, whereas in the non-pixel portions (14) the orientation asymmetricity is intensified, so that a uniform clarity may be obtained.

Abstract: In a wafer scale integrated circuit device having functional blocks (2 11 ,2 12 ,...2 nm ) in rows and columns on the wafer (1) each of blocks are interconnected by local lines, power supply lines, and input signal lines constituted by a command signal transmitting line (43) and a wafer clock signal transmitting line (42). Input protection (5 11 ,5 12 ,...5 nm ; 6 11 ,6 12 ...6 nm ) for preventing an overshot or undershot level of the input signal are provided between each functional block and the command signal transmitting line (43) and the wafer clock signal transmitting line (42). Consequently, the input command signal (CMND) and the wafer clock signal (WCK) are delayed and rounded to the same degree for each and every functional block. Therefore, a high operational speed with a small operational margin can be realized by preventing synchronization error.

Abstract: Compounds of the general formula
      are cyclised to the corresponding isothiazolinone using a carbonyl halide of the formula RCOX where R is halogen or alkyl and X is halogen. R³ and R⁴ are preferably such as to form a 5 or 6 membered ring. Useful carbonyl halides are phosgene and propionyl chloride. Using acyl halides such as propionyl chloride, a mixture of the isothiazolinone and a salt of the carboxylic acid can be obtained, for example an essentially equimolar mixture of 2-methyl-4,5-­trimethyl-4-isothiazolin-3-one and sodium propionate.

Abstract: The blood sampling device consists of a blood sampling tube (1) with a screw cap (2), which has an attachment (3) for receiving a needle adapter, a piston (4) guided in the tube (1) and a piston rod (5) connected to the piston. At the point of connection to the piston the piston rod (5) has a predetermined breaking point (5.1). Provided on the blood sampling tube (1) between the frontmost and rearmost piston positions are markings (1a, 1b) which in each case indicate partial volumes of the full tube volume. The piston rod has at least one further predetermined breaking point (5.2, 5.3) which is in each case assigned to a marking (1a, 1b). In this way it is possible also to take up partial volumes of blood which do not correspond to the full tube volume. <IMAGE>

Abstract: 1. Heat exchange apparatus, in which solid particles are guided in an internal circuit. 2.1 In heat exchangers in which solid particles are guided for the purpose of tube cleaning in an internal circuit, so-called fluidised bed heat exchangers, problems arise during start up and in stationary mode, which are caused both by the particles themselves and by the influences on the tubular flow due to pulsations in the inlet chamber and outlet chamber. It is the object of the invention to improve the operational reliability and efficiency of such heat exchangers with the aid of simple structural means. 2.2 This object is achieved when for the purpose of forming an antechamber a perforated plate is arranged in the outlet chamber at a distance above the upper tube base and has at least one through opening which is separated from the antechamber by one or more separating plates.

IPC: C07C51/56

Abstract: The methyl iodide recycle stream to a carbonylation reactor for carbonylating methanol or methyl acetate to acetic acid, acetic anhydride or both is treated to remove carbonyl impurities by reacting the methyl iodide stream with an aqueous amino compound which reacts with the carbonyls to form water soluble nitrogenous derivatives, separating an organic methyl iodide phase from an aqueous derivative phase and distilling the methyl iodide phase to remove heavier impurities. The treatment of the methyl iodide recycle stream to the carbonylation reactor has been found to greatly reduce the carbonyls present in the product acetic acid or acetic anhydride and reduce tar formation in acetic anhydride and acetic acid-acetic anhydride co-production units. The formation of nitrile from the nitrogenous derivative during distillation is minimized by adding water to the distillation column which washes the nitrogenous derivatives from the methyl iodide overhead.

Abstract: A method for changing the sample rate of a sampled signal into another sample rate, comprising the following method steps:   a) When the sample rate is reduced, the sampled signal is conducted through such a digital filter that the highest frequency occurring in the spectrum present after the filtering is lower than or equal to half of the sampling frequency to be newly generated. b) When the sample rate is increased, the sampled signal is conducted through such a digital filter that within the frequency range between less than or equal to half the original and half the new sample rate no spectral interference terms occur. Via the requirements for band limiting specified in a and b, the digital filter can be used in both cases, that is to say of reduction and increasing the sample rate, for an even greater band limiting and/or spectral shaping of the signal at the input of the apparatus for sample rate conversion.   c) The signal produced is sampled at the new sample rate.   <IMAGE>

Abstract: A direct drive pressure control valve for hydraulic systems is described with a valve housing (1) with a primary connection (18), a secondary connection (19) and a pressure relief connection (20). In a stepped housing bore a control sleeve (5) is held so as to be axially movable, on on an annular piston face (6) of which the pressure medium acts under the pressure of the secondary connection (19) and the effective force of the pressure medium is counterbalanced by a working spring (26). A control slide valve (9) with axially succeeding pistons (10, 11) of equal size is located in the internal bore of the control sleeve (5). Should the pressure in the secondary connection (19) and thereby in the line to the consuming unit be increased, a connection from the primary connection (18) to the secondary connection (19) is opened by axial displacement of the control slide valve (5). Under the effect of the increase in pressure in the secondary connection (19) and hence in the control pressure chamber (8), the control sleeve (5) moves against the force of the working spring (26), thereby blocking the connection between primary connection (18) and secondary connection (19) on attaining the rated pressure. In the process the pressure of the pressure medium has no reaction on the control slide valve (9). Only the force of a relatively small control spring (16) needs to be overcome for operation to occur. In the case of a positive connection of the control slide valve (9) to a suitable operating element (17) such a control spring is not necessary. <IMAGE>

Abstract: Each of the signal processing units of a digital signal processing system is provided with a programmable timing delay unit having identical programming interface to control the signal timing of its signal processing circuitry. Additionally, a central timing unit is provided to the digital signal processing system to provide signal timing control inputs to the programmable timing delay units. Furthermore, a routing switcher is provided to the digital signal processing system to control configuration of the signal path, i.e. the order in which the signal is processed by all or a subset of the signal processing units of the digital signal processing system. As a result, the individual signal processing units are relieved the burden of providing circuitry for timing control, delay equalization and timing derivation. Furthermore, the timing offsets for the individual signal processing units may be easily recomputed for any signal path, thereby improving the reconfiguration flexibility of the digital signal processing system.
