Abstract: Several large-screen displays making use of liquid crystal light valve (5) have been realized. The photoactivated liquid crystal light valve (5) is composed by intervening a photo­conductor layer (25) between a liquid crystal layer (26) and an electrode (21b). The photoconductor layer (25) is changed in its impedance when exposed with light. Therefore, when light is emitted to the photoconductor layer (25) while a voltage is applied between electrodes (21a, 21b), the voltage applied to the exposed portion varies, and the orientation state of the liquid crystal layer (26) changes, and an image is formed on the liquid crystal layer (26). The structure for emitting/­interrupting the light mentioned above may be reduced in size by using liquid crystal shutter arrays (3, 4). As the liquid crystal layer (26) to be used in the liquid crystal shutter arrays (3, 4), SmC* phase liquid crystal showing a ferro­dielectric property may be used, so that the response may be enhanced. Therefore, not limited to the still picture display alone, a moving picture may be also displayed. Still more, since the liquid crystal shutter arrays (3, 4) are statically driven, the control is easy, and the number of electrodes (21a, 21b) may be increased, so that the image of high resolution may be displayed on the liquid crystal display valve (5).

Abstract: In a dual bus microcomputer system using a cache memory and a cache controller, the timing requirements placed on non-cache memory components by the cache controller are more stringent than the timing requirements placed on the non-cache memory components by the microprocessor. A logic circuit operates on the cache write enable (CWE) signals, and delays those signals in the event of a cache read miss. Delaying the CWE signals relaxes the timing requirements placed on non-cache memory components and at the same time does not impact wait state parameters for read miss operations.

Abstract: Diverse routing can be achieved by using two completely separate optical systems to send the same signal along diverse routes simultaneously; or, by splitting the optical fiber by means of a fused-fiber (3dB) splitter to send the same signal along two diverse routes. A 2x2 electro-mechanical optical switch can be used to select the appropriate optical fiber. 
     A 3dB splitter is more economical than two separate optical systems. However, the 3dB splitter introduces a loss factor which is excessive. 
     An optical modulator can be substituted for a beam splitter. The modulator, often comprising a lithium niobate switch, is used to impress a digital signal on a dc optical beam. The lithium niobate modulator has a cw optical input, an electrical control input representative of digital data, and normally two digital optical outputs. One output is generally used as the modulated line signal, and the other output, which is the complement of the modulated signal, is terminated in an index matching oil to prevent reflection. 
     Briefly, in this invention, the previously discarded digital optical output of the optical mode is not discarded. It is used as a signal source for the diverse route thereby avoiding the need for any further loss producing beam splitters. The advantages are significant. The laser is on continuously. Therefore, there is no chirp. The power (on average) is directed 50% of the time to one output and 50% of the time to the other output. Thus, there is no power loss as in the case when a splitter is used. Where appropriate, at the receiving end, complementation can be performed to retrieve the original bit pattern if the complement of the signal is being detected.

Abstract: An electric motor (10) has first, second and third stator windings (11, 12, 13) supplied by a source of alternating voltage having three phases A, B and C, respectively. A separate thyristor switch assembly (16, 17, 18) couples each stator winding to an alternating voltage phase when said switch means is rendered conductive by a trigger signal. When the speed of the motor is above a first predefined level, the thyristor switch assemblies (16, 17, 18) are triggered, in response of the polarity of the voltage between phases A and B being opposed to the polarity of back emf voltage induced across the third winding (13), to apply current through said first and second stator windings (11, 12). However, when the speed of the motor is below the first predefined level, the thyristor switch assemblies (16, 17, 18) are triggered, in response to the polarity of the voltage between phases B and C being opposed to the polarity of back emf voltage induced across the third winding, to apply current through said second and third stator windings (12, 13). Subsequently when the speed of the motor further decreases below a second predefined level, current is applied through said second and third stator windings (12, 13) during every cycle of the voltage between phases B and C.

Abstract: When a new virtual connection is set up via an ATM line, a check is carried out to ascertain whether the still available free transmission power is adequate for the transmission power required for the virtual connection which is to be newly set up. Every subscriber reports in advance its mean bit rate and its peak bit rate, which values must not then be exceeded. When a new connection is set up, the new total load is calculated from the mean bit rates and the peak bit rates. This is compared with the relevant overall peak bit rate which is permissible for the ATM line concerned; the required new virtual connection is set up only if said total load does not exceed said overall peak bit rate. The calculation entails subtraction, multiplication, addition, root extraction and further technically implemented operations. <IMAGE>

Ceramic starting material is applied in the mould cavity and is subjected to compressive force. The unit produced in this way is released or removed and is treated in one or more sintering procedures in which it is subjected to linear shrinkage until the contour defined by the tool part has essentially the same size as the model contour.
