Abstract: A diaphragm valve comprises a housing (1) provided with a supply and a discharge opening, and adapted to be inserted in a conduit. A sleeve-shaped elastic diaphragm (4) is accomodated in the housing (1), and extends between the openings. The diaphragm (4) is adapted to be loaded from the outside by a pressure fluid. In its unloaded condition, the diaphragm (4) is at a radial distance from a core body (5) located centrally therein, and the valve is open. In its fully loaded condition, a middle section (11) of the diaphragm (4) is pressed against the core body (5), and the valve is closed. The wall of the resilient diaphragm has means (10) for increasing its stiffness. These means (10) only extend from an end of the diaphragm (4) to a place near its middle section (11), thus simplifying manufacture of the diaphragm (4) and improving its sealing.

Abstract: In a color liquid crystal display device (1) according to this invention, since the color filter (3) is provided over the entire surface of the glass substrate (2a), the shape of the color filter (3) cannot be seen and parts where the color filter (3) is provided do not appear colored. Also, since the light passing through the liquid crystal layer (23) becomes white light due to the mixing of the three colors red, green and blue, coloring of areas other than the display area is prevented. 
     In a color liquid crystal display device (21), the transmissivity of light passing through the liquid crystal layer (29) can be varied in levels by making the display electrodes (23,26) in two-layer, operating voltage on each of the electrodes independently, and varying in levels the amplitude of voltage applied on the liquid crystal layer (29) by the display electrodes (23,26). 
     In a color liquid crystal display device (51), the amount of light transmitted in the display area can be varied by varying the area on which voltage is applied on the display electrodes (53,56). 
     In this manner, the same color can be displayed in a plurality of levels, thus increasing the variety of display colors and improving the diversity of display. 
     Further, in a color liquid crystal display device (71)   by disposing a third polarizer plate (88) between the first and second liquid crystal elements (72,73), the linearly polarized light transmitted by the liquid crystal layer (79) when voltage is applied on the first liquid crystal element (72) is blocked by the third polarizer plate (88) and does not reach the second liquid crystal element (73). Therefore, the display color is prevented from becoming a complementary color even in the area where the area in which the first display electrodes (76) are formed and the area in which the second display electrodes (82) are formed overlap, thus improving display quality.

Abstract: The present invention is a system that interacts with the translator user by requesting information relevant to process operating procedures. Information such as constraints on the process and the logic for ascertaining completion of various procedure steps are obtained from the user, such as a technician or plant operator, who is providing the information from a previously created written procedure or procedure flow diagram or from a user such as a plant design engineer, who is creating a procedure for a newly designed process. The system requests the information from the user in an order which allows the technician to follow the written procedure in answering system queries or in a top down order as would be the design approach taken by the engineer. As query answers are provided, lines of executable code in various procedure templates are completed and written to temporary files. After all queries are answered for a particular step within a procedure, the system arranges the template code in an order that ensures all variable values are read in or calculated before they are needed and that all plant operator response requests appear in the appropriate position in the procedure that is produced on the operator monitor as the procedure is executed. The system also allows the translator to designate other procedures for execution or initiate other actions such as production of nonprocedural displays on adjacent monitors. The information appearing on the operator monitor and any adjacent monitors, and produced or initiated by the code, aids the operator in performing the procedure correctly.
