Abstract: A matrix display device, suitable for displaying TV pictures, has a plurality of display elements (20) arranged in a matrix array and defined by electrodes (33 and 41) on opposing substrates with, for example, liquid crystal material (32) therebetween and with the display elements being individually controllable via switching elements (40) such as thin film transistors. Each display element is sub-divided into a plurality of sub-elements using a plurality of sub-electrodes (55) on one substrate which are each connected via a series capacitor (C X ) to a switching element, the ratio of capacitances of the sub-elements to their respective series capacitors differing from one another. As applied voltage is increased, progressively more sub-elements are caused to change state providing in effect various grey scale levels. Display materials having comparatively sharp switching characteristics can be used.

Abstract: An output driver circuit is described which can be programmed by the user into tri-state or open-­collector configurations, depending on the needs of the user. The driver circuit comprises a pair of a first pull-up (24) and a pull-down (26) FET transistor. The source of the pull-up transistor (24) and drain of the pull-down transistor (26) are both connected to the output of the driver. The gates of the pair of transistors are controlled by an input signal and its complement. The driver further includes a second pull-up FET (76) whose source is conntected to the output of the driver. The channel width to channel length ratio of the second pull-up transistor is at least about an order of magnitude greater than that of the first pull-up transistor. The driver further includes a control means (74) responsive to the input signal for applying a second signal to the gate of the second pull-up transistor for programming the driver into tri-state or open-collector modes. The driver circuit may be controlled by the output of an OR gate in an AND-OR array in a FPLA or PAL device. The driver is programmable by programming the AND gate or OR gate array and applying selected input signals to the AND gate array; the driver can also be programmed permanently into the tri-state or open-collector mode.

Abstract: On the inside of the shaft (12) of the ski boot (10), there are provided a holding element (18), which acts on the inner boot (16) in the instep region, and a heel cap (20). The draw member (30) forms a first part loop (32) which is guided over the front end region (36) of the holding element (18), from there runs towards the sole (14) and is diverted in the sole (14) in such a manner that its sections (42) run from the rear towards the nut (28). The second part loop (34) is guided over the upper end region (38) of the holding element (18), runs to the guide elements (40) of the heel cap (20) and is from there, crossing itself, guided to the nut (28). The nut (28) is located on the spindle (22) which is rotatable by means of the servomotor (26). By displacing the nut (28) in the longitudinal direction (A) of the boot towards the toe of the foot, the size of both part loops (32, 34) is reduced, so that the holding element (18) and the heel cap (20) can bear against the inner boot (16) and this can bear against the foot. By displacing the nut (28) in the direction towards the heel, both part loops (32, 34) are enlarged, so that it is possible to put on and remove the ski boot (10) without problems.

Abstract: A compression ratio-changing device for an internal combustion engine includes a rotary eccentric member (4) rotatably interposed between a piston and a connecting rod (3), a locking pin (9) for locking the rotary eccentric member to the connecting rod, and a device for driving the locking pin to selectively hold the rotary eccentric member to the connecting rod and release same therefrom. A sliding groove (7) formed in the connecting rod is disposed for parallel alignment with a guide groove (8) formed in the rotary eccentric member when the rotary eccentric member assumes a first angular position for decreasing the volume of a combustion chamber of the engine at a top dead center position of the piston to obtain a higher compression ratio, or a second angular position for increasing the volume of the combustion chamber at the top dead center position of the piston to obtain a lower compression ratio. The locking pin is disposed to be held between the guide groove and the sliding groove when the guide groove is in parallel alignment with the sliding groove, thereby locking the rotary eccentric member to the connecting rod.

Abstract: A rotary distributor type fuel injection pump has a pair of angularly adjustable stop rings (25) having shaped internal surfaces which can engage with the cam followers of the pump to limit the outward movement of the pump plungers. The stop rings are interconnected by a saddle member (27-35) and a spring (38) biases the saddle member into engagement with a stop (35A). The stop which may be adjustable determines the normal maximum amount of fuel which can be supplied by the pump. For starting purposes the stop rings are moved to an excess fuel position which is achieved by a pin (42) engaged in a slot (43) in one of the rings. The pin is spring biased to move the one end and hence the other ring to an excess fuel position and is coupled to a fluid pressure operable piston which when the associated engine is started is moved by fluid pressure to move the pin (42) to allow the spring (38) to move the saddle member and stop into engagement with the stop (35A).

Abstract: Fault tolerant apparatus for generating error correcting code and, simultaneous therewith, checking the correctness of the generation, for blocks of data with which the error correcting code is associated and transmitted to a storage medium. The apparatus includes a pair of programmable control devices configured to selectively operate in one of two modes: A first mode in which data being transferred to the storage medium is monitored for generation of an error correcting code to be associated and stored with each data block, and a second mode in which the data being transferred is monitored for detecting errors that may be contained in the data. During data transmissions to the storage device, one of the control devices operates in the first mode, while the other control device operates in the second mode to check operation of the first device. When data is retrieved from the storage device, both control devices operate in the second mode to check the correctness of the data being transferred, and the operability of each other.
