Patent EP-0328081-A2 (EP)
Inventor: HIGASHIMURA HIDEAKI C O ITAMI
IPC: B60T8/66
Filed: 1989-02-08
Abstract: The device, for use with the brake assembly of a motor vehicle, includes a program for detecting any malfunction of wheel speed sensors (S3, S4) for the non-driven wheels. The program is adapted to judge that the non-driven wheel sensors (S3, S4) are out of order and give a signal notifying the abnormality of the sensors (S3, S4), if the wheel speed values detected by the non-driven wheels are kept out of a predetermined range for a predetermined period while the wheel speeds detected by the driven wheel speed sensors (S1, S2) are above a predetermined point. Thus, the possible malfunction of the antilock device itself will be notified or prevented which may result from wrong information from the troubled non-driven wheel sensors (S3, S4).

Abstract: The service trolley has a cuboid body (1) which can be closed at the front and/or rear side by a door leaf (2) which is attached by means of a hinge. In order to protect the hinge against impacts and to guide the door leaf (2) tautly through the hinge whilst retaining easy usability, provision is made for the hinge to have two parallel swivel axles (4, 11), one of which is mounted in corresponding bearings on the body (1) and the other in corresponding bearings on the door leaf (2). The two swivel axles (4, 11) are passed through the assigned bearings of at least two spaced-apart hinge bodies (5), at least one of the swivel axles (4, 11) being connected, on the one hand, to the hinge bodies (5) or, on the other hand, fixedly in terms of rotation to the door leaf (2) or the body (1).

Abstract: In a portable radio telephone apparatus, a desired one of interchangeable battery packs (2) is mounted. Each battery pack (2) contains a rechargeable battery (24) of a particular ampere-hour rating and a switch (23) for identifying the ampere-hour rating of the battery being used. In one em­bodiment, multiple charging circuits (31, 32) are selectively connected to the battery in accordance with the identification given by the switch for charging it with a current that is optimum for the battery's ampere-hour rating. In another embodiment, the charging circuit includes a switching regulator circuit for generating a charging voltage that can be varied in accordance with a control signal applied thereto. The control signal is derived by detecting a difference between the charging voltage and a reference voltage. The switching regulator controls the charging voltage so that the voltage difference reduces to zero.

Abstract: A substantially constant current is divided between two lines in accordance with the relative values of an input voltage and a reference voltage respectively introduced to such lines. The currents through the first and second lines respectively charge first and second capacitances. The charges in the first and second capacitances respectively control the magnitudes of the currents flowing through first and second control members to charge the first and second capacitances. The control members are interconnected so that any difference between the flow of current through the control members and the associated capacitances becomes magnified. When the charge in an individual one of the capacitances reaches a particular value, a signal on an output terminal associated with the other capacitance changes from the first magnitude to a second magnitude. During this time, the signal associated with the first capacitance remains at substantially the first magnitude. A plurality of stages, including the comparators disccussed above, compare the input voltage with progressive values of the reference voltage. Such stages are connected to successive pairs of comparators to indicate, on the basis of the relative magnitudes of the voltages on the output terminals of such comparators, whether the reference voltage is greater than the input voltage for both comparators in such pairs. An output signal is produced by the plurality only when one pair of comparators provides an output indicating that the input voltage is between the reference voltages connected to that pair of comparators.

Abstract: The intermediate enrichment of trace substances from a gas stream is effected using a cold trap through which the gas stream flows and which optionally contains adsorber material and is enclosed by a gas-tight twin jacket into which cooling liquid from a surrounding cooling bath can penetrate via a lower extension tube. For desorption, the cooling liquid is displaced from the twin jacket by means of compressed air under valve control. A tube loop connected to the twin jacket and provided with a heating coil and circulation pipe facilitates rapid warming of the cold trap. Level-regulating means connected to the compressed air line permit sensitive adjustment of the level in the lower extension tube of the twin jacket during the desorption phase. <IMAGE>

Abstract: Integral linearity error in the operating characteristics of an analog to digital converter employing sampling comparators (12) is reduced by generating a further error in a sense to offset said linearity error at least in part. This is achieved, in a preferred embodiment, by recurrently connecting (31) at least one resistive shunt (28) across a predetermined central portion of a reference voltage divider input (22) to the comparators. The shunt resistance is approximately an order of magnitude larger than the resistance of the shunted part of the divider. Each recurrent connection interval is of fixed duration independent of sampling rate, and each interval spans the beginning of a recurrent time of connection of said divider to said comparators.

Abstract: The multiplex device of the flexible multiplex system is used for dividing a multiplex channel into several subscriber channels (CH1 to CH6). Each data input (E1 to E6) is associated with one serial/parallel converter (SPU1 to SPU6), the parallel outputs of which are connected via a data bus (DBM) to a parallel/serial converter (PSU) which outputs at its output the multiplex signal (MS). A memory control (STS) specifies the number of subscriber channels (CH1 to CH6) and their data rate. It also provides for the insertion of the frame alignment words (SO1, SO2) and of the signalling words (DO1 to DO6) at the correct time. The demultiplex device is constructed to correspond to the multiplex device. <IMAGE>
