IPC: G02F3/02
Filed: 1990-04-26
Abstract: The invention is based on the effect of the optical bistability and the redistribution of the electric field in semiconductor structures as a consequence of the formation of unbalanced carriers under the influence of optical radiation. The trigger comprises two identical cells (1), which are connected by an electric circuit. The switchover of the optical channels (I, II) is performed by the control light i, which comes via the mutually separated channels (I, II). <IMAGE>

Abstract: Liquid-crystalline materials are becoming increasingly important in electrooptical switching and display devices. Recently, ferroelectric liquid-crystalline mixtures have also been investigated widely and employed in displays. A particularly important physical parameter for describing FLC mixtures is the spontaneous polarisation (Ps). On the one hand, a high spontaneous polarisation results in short response times, but on the other hand, high Ps values result in optical hysteresis, which causes, inter alia, so-called "ghost images". The use of FLC mixtures of high spontaneous polarisation (Ps 20 nC/cm<2>) and a natural helical pitch of less than half the layer thickness in an SSFLC display having a layer thickness of from 1 to 10  mu m allows the problem of optical hysteresis to be circumvented, in spite of the high spontaneous polarisation. FLC mixtures in which Ps is > 40 nC/cm<2> can also be switched under these conditions.

IPC: H02P7/285
Filed: 1990-09-06
Abstract: A digital current control arrangement for optimizing the transport time delay of a thyristor power supply used as a source of armature current for a DC motor utilizes a coarse gate angle interrupt subroutine to perform a preliminary calculation of the gate firing angle for the next thyristor to be fired. The coarse gate angle calculation is performed at a predetermined time following the firing of a previous thyristor. A finite gate angle interrupt subroutine is also provided for recalculating the gate firing angle at a second predetermined time just prior to the firing of the thyristor. The finite and coarse gate angle interrupt subroutines both perform their respective calculations using the common parameters. A flag passing arrangement is also included in the current control arrangement and is effective to insure that the finite gate firing angle is the preferred calculation used in the firing of the next thyristor.

Abstract: The invention is based on a method for treating, including flushing, objects (1, 1') such as printed-circuit boards, especially constructed in the form of boards, by means of a flowing fluid which is applied to the objects as a flowing wave, the objects preferably being transported in the horizontal position and being able to have continuous holes (4) and/or blind holes (5). In order to facilitate the advantage of a uniform wave flow with a production cost which is significantly lower than the prior art it is provided to this end that the fluid flow is given a flattened form (13) with an approximately uniform thin cross-section by spreading the fluid flow apart, preferably into a plurality of partial fluid flows (10) which are located side-by-side at a distance and are of approximately circular cross-section, that this flattened fluid flow (13) runs approximately at right angles to the transportation direction (2) of the objects (1, 1') to be treated and is applied to the object at an incidence angle ( alpha ). The invention furthermore relates to a device for carrying out the method, having a plate-shaped guide device (12), which is at an acute impact angle ( beta ) with respect to the outlet direction (10) of the treatment fluid and forms the incidence angle ( alpha ) with respect to the object to be treated. <IMAGE>

Abstract: An electric blanket includes a heating element comprising inner and outer coaxial coil conductors (R1, R2) separated by an electrically insulating layer (10) and connected by a diode (D3). A control assembly (12) is connected to the heating element by a simple two-core flexible electrical cable (11) and incorporates a thyristor (S1) and a thyristor control circuit (15) to vary the supply of current to the heating element. Protective diodes (D1, D2) are connected in parallel with the main heating conductor (R1) , and also, (D4, D5,) in parallel with the thyristor (S1) . Should the heating element overheat the insulating layer (10) breaks down causing a short circuit between the conductors (R1, R2) and the surge of current allowed by the protective diodes (D1, D2, D4, D5) causes a fuse (F1) to blow. The conductor (R2) is always in series with the protective diodes so that in the event of transient breakdown of one of the diodes the resistance of the conductor (R2) prevents fuse operation.

Abstract: A local oscillator and its frequency switching method, in which local signals with less spurious components can be obtained. Frequency generators (31,32) for generating signals with different frequencies and frequency dividers (33,34) respectively connected to the generators are provided. The dividers (33,34) divide in frequency the signals to output them in an active mode, and output the signals without division in inactive mode. The dividers are controlled so that one of the dividers is in the active mode and the rest is in inactive mode. The output signals from the dividers are combined (37) with each other to form a single output current which is sent to a filter (38). The filter selects a component with a desired local frequency from the single output signal. Spurious components due to unselected frequencies are removed by the filter since they are not divided.
