Patent EP-0368554-A2 (EP)
Inventor: SUZUKI SHUNJI
IPC: G02F1/133
Filed: 1989-11-01
Abstract: The present invention relates to a twisted nematic liquid crystal display device comprising a first transparent electrode which has been subjected to orientation treatment in a first direction, a second transparent electrode which has been subjected to orientation treatment in a second direction, a liquid crystal layer, the major axes of the molecules of which have been subjected to twisted orientation by 90°, located between said first and second electrodes, a first transparent polarizing plate having a direction of polarization coinciding with the first direction and located outside the first electrode, and a second transparent polarizing plate having a direction of polarization coinciding with the second direction and located outside the second electrode. In such a device, when no voltage is applied between the two electrodes, light incident on the first polarizing plate is not able to pass through the liquid crystal layer due to the twisted orientation through 90° of the major axes of the molecules of said liquid crystal layer. However, when an excitation voltage is applied between the two electrodes, the major axes of the molecules of the liquid crystal layer are re-orientated so as to lie parallel to the electric field and light incident on the first polarizing plate is able to pass through the liquid crystal layer and out through the second polarizing plate. 
     According to the invention, the display device is characterised in that the optical path length difference (Δnd) of the liquid crystal layer, which is equal to the product of the thickness (d) of the liquid crystal layer and the double refraction index (Δd) of the liquid crystal layer, has a value such that 1.4 µm ≦ Δnd ≦ 1.7 µm.

Abstract: What is described is a method for operating a ring spinning machine, in which the traversing movement of the ring rail (10) is generated by means of a heart sheave (70). To perform specific functions dependent on the rotary-angle position of the heart sheave (70), the rotation time of the heart sheave (70) is first determined. A predetermined initial rotary-angle position of this heart sheave is then ascertained, and starting from the specific rotation time the time from the occurrence of the initial rotary-angle position to the occurrence of at least one further predetermined rotary-angle position assigned a respective function is calculated in each case. The particular function is performed when the time assigned to a respective rotary-angle position has elapsed. …<IMAGE>…

Abstract: In order to adjust the ink metering device of a printing press to a zero ink application position at any time, the control (6, 7, 8) of the ink metering device is extended by a control device (9) and the position indicators (5) of the ink metering elements (1) are constructed as sensors (13). The control device (9) switches on the adjusting drives (2) of the ink metering elements (1) in the direction of the inking roller (3), determines whether the measurement signals of the position indicators (5) change with time and switches off those adjusting drives (2) of the ink metering elements (1) whose positions no longer change with time since the ink metering elements (1) are resting on the inking roller (3). These zero positions of the individual ink metering elements (1) can be stored in the control (6, 7, 8) for the further adjusting operations.   <IMAGE>

Abstract: An improved RAM has a dummy word line (DWL) having the same pattern and same gate as the word lines provided RAM cells (101) in order to detect that one of word lines (WL₁-WL n ) is selected until the end of the word lines, then operate a sense amplifier (109). A transistor (T₁) having the same W/L (W: channel width; L: channel length) as an output transistor (T₁) in the RAM cell is connected in series between a transistor (T₂) similar to a transfer gate (T₂) in the RAM cell at the final stage and a ground voltage supply, for example, and receives an enable signal as its gate input. Provided between the transistor (T₂) and a V DD  voltage supply a transistor (T₃) which has a different polarity from that of the second transistor (T₁), and receives the enable signal as its gate input. Accordingly, the second and third transistors (T₁, T₃) constitute an inverter (151). The capacitance (C₂) of the drain portion of this inverter is set close to the capacitance (C₁) of the bus line on the RAM side, thereby adjust the dummy word line (DWL) and the word lines on the RAM circuit side to have the same transfer delay. If the drain capacitance (C₂) on the dummy side corresponding to the bus line is adjusted slightly smaller than the bus line capacitance, the potential of the drain can be changed by this slight difference. This drain potential when detected can be used as a drive signal to drive the sense amplifier. Further, the signal traveling through the dummy word line can be used as a precharge signal.

Moreover, the closing part (4') extends in closed position immediately adjacent and parallel to an auxiliary air admission opening (3) situated in the front surface. The flow-conducting walls (11) of the housing (1) are designed converging towards the chimney connection piece (6) and lastly the width of the admission opening (3) is dimensioned only slightly smaller than the width of the housing (1). <IMAGE>

Abstract: The present specification discloses an apparatus and method for producing concrete beams for use in the construction industry. Concrete beams are conventionally made in suitable moulds in a factory, the beams being removed from the mould and transferred to the construction site. However, removal from the mould and transit can cause the beams to be damaged, besides adding to the production cost. 
     The present invention provides an apparatus which is manhandlable without the need for lifting gear, and which can be used on site, thereby reducing production cost and the possibility of damage. The apparatus comprises a number of vertical supports (5) between which horizontal support members (7) extend. Elongate mould members (17) rest generally horizontally on the support members (7), abutting one another so as to define a number of adjacent, parallel, generally U-shaped channels (19). In use, concrete is poured into the channels (19) and after hardening the mould members (17) are separated, it being a relatively easy operation to release the L-shaped mould members (17) from the beams with little, if any, damage.

Abstract: Systems for storing and dispensing gases. The gas storage systems are two-phase gas/solid or gas/liquid, or three-phase gas/liquid/solid, functioning by reversible sorption. In gas storage systems having a solid phase, use is made of a polymeric material, preferably a hydrogel, having microvoids functioning as interstitial stores for gas. Reversible gas sorption in the microporous polymer is improved by treatment with a swelling promoter. The stored gas may be a propellant, and reversible sorption propellant storage may be used in all types of pressure pack dispenser. Cryogenic techniques facilitate preparation of propellant systems with standardised parameters. The invention enables use of safe and environmentally benign gases as propellants.
