Title: Control device for a friction clutch of a lockable differential of a motor vehicle
Inventor: HONZEK ROBERT
IPC: F16H48/30
Filed: 1987-02-24
Abstract: A control device for a friction clutch of a lockable differential for motor vehicles is described, in which, in the power flow from a longitudinally movable control element to a pressure plate 14, a power increasing element is arranged on the clutch 11 which is housed inside the differential housing 3, which power increasing element acts on a pressure piece which loads the pressure plate 14. In order to be able to engage and retain the clutch 11 with the aid of a relatively weak, physically small electromagnet, the power increasing element and a plurality of rocker arms 15a forming the pressure piece interact in the manner of a bell crank. In this way, the axial force required to close the clutch 11 can be generated by a relatively small control force to be applied by the electromagnet. <IMAGE>

Abstract: Catalyst solution contaminated during the carbonylation of methyl acetate and/or dimethylether. To this end, the contaminated catalyst solution is subjected in a first processing stage to extraction with a dialkylether and alkanol, each of which has from 1-4 carbon atoms per alkyl group, and thereby freed from its organic contaminants, from acetic acid, acetic anhydride and ethylidene diacetate, and the ether phase is separated from the purified promoter-containing catalyst solution; next, the ether phase is treated in a second processing stage with iodine and/or methyl iodide; the precipitated promoter containing catalyst complex is separated and dissolved in the purified catalyst solution coming from the first processing stage; the ether phase is separated into its constituents by distilling it; recovered dialkylether and alkanol are used again in the extraction stage; fresh catalyst solution is prepared from the recovered mixture of acetic acid, acetic anhydride and ethylidene diacetate and from the united purified catalyst solution while residual dialkylether and alkanol are distilled off, and the organic contaminants retained in the residue of the ether phase distillation are expelled.

Abstract: In this data processing device, a request for direct memory-access operation is detected as one of interrupt signals. When such an interrupt is detected, a interrupt controller (10) generates a vector corresponding to the interrupt signal. On the basis of this vector, a DMA controller (20) generates a control signal showing whether the interrupt signal is a normal interrupt or an interrupt for requesting the direct memory-access operation. A CPU (30) includes a ROM (34) for storing the control function for achieving the direct memory-access operation, as micro-codes. When the DMA controller (20) generates a control signal corresponding to the interrupt signal, the CPU (30) sequentially reads out the micro-codes, to execute the direct memory-access operation. Specifically, if an interrupt for requesting the direct memory-access operation is detected, a processing space, different from that used for a normal interrupt processing, is used. The processing area has a prestorage of the data . corresponding to the data stored in various types of registers provided in the conventional DMA controller. By using this data, the data transfer is controlled by the micro-codes.

Abstract: A terminal communications network that provides communica­tion through a bus interface circuit to a network bus in accordance with the predetermined communications procedure, the terminal communications circuit (100) including a communica­tions interchange circuit (132) that exchanges protocol signals with the bus interface circuit in response to commands received from a signal state controller that is resident in the ter­minal. The communications interchange circuit (132) further provides communications state change information to the signal state controller to indicate the contents of the protocol signals from the bus information circuit. The signal state controller executes one of a plurality of program states to control communications over the network bus in accordance with predetermined communications procedure by providing commands to the communications interchange circuit in accordance with the program state that the signal state controller is currently executing. The signal state controller changes the program state in response to the communications state change informa­tion from the communications interchange circuit. Also pro­vided is a single command from the signal state controller to the communications interchange circuit that results in the communications interchange circuit providing a multiple of individual protocol signal patterns to the bus interface circuit enabling multiple communications procedures to be performed on the communications network with a single command from the signal state controller.

Abstract: A means and method for forming a single tub transistor, such as for example a vertical NPN bipolar transistor surrounded by an isolation wall, is described. Multiple polysilicon (22,26,68,80) and dielectric layers (20,24,36) are employed in conjunction with a master mask (30,40,41,42,43) and with isotropic and anisotropic etching procedures to define the contacts (80C,80E) and active regions (76,64,16) of the device without resorting to precision alignments. Sub-micron lateral device contacts (80C,80E) are easily achieved even with comparatively coarse lithographic methods through use of sidewall spacers (67,68) for controlled narrowing of critical device openings (41,42). The finished device is especially compact, has low resistance contacts for its size, and provides very high speed operation.

The MOSFET (19) and the auxiliary thyristor (27) are controlled by an output of a gate energization cir­cuit. When the MOSFET (19) is turned on by an output of the gate energization circuit, the main thyristor (26) is connected to the auxiliary thyristor (27). At this time, the auxiliary thyristor (27) is turned on by the output of the gate energization circuit, and the main thyristor (26) is also turned on due to the turn-on operation of the auxiliary thyristor (27). When the MOSFET (19) is in the OFF state, the main thyristor (26) is electrically isolated from the auxiliary thyristor (27).

Abstract: Food material is introduced into a space (27) formed between the periphery of a drum (9) and the wall of a housing (7). The drum has an inner chamber (31) between its inner wall and the periphery of a cam (19). A pair of blades (15) is inserted into slits (13) formed on the drum so as to form a compartment on the outside of the drum and a compartment in the inner chamber (21). 
     The dimensions of the outer compartment decrease towards the exit port (23), while those of the inner compartment increase, so a pressure differential is established and any air in the mater­ial is drawn into the inner chamber via a recess (17) on the trailing surface of the blade (15). Material of a uniform quantity and density, and that has no air entrainment, is thus extruded from the exit port.
