Patent EP-0326220-A2 (EP)
Inventor: ALBACH MANFRED
IPC: H02M1/00
Filed: 1989-01-24
Abstract: A circuit arrangement for feeding a load (3) from a low voltage energy source (1) via a direct-voltage conversion circuit (2). The direct-voltage conversion circuit periodically takes energy from the energy source by means of a main switching element (10) and supplies this energy as an increased supply voltage (at 12) to the load via an inductive element (9) and a rectifier (11). A starting switching element (15) takes energy for generating the supply voltage (at 12) from the energy source during a starting phase. The circuit arrangement is simple and compact and the energy losses produced are so low that it is economic to use it for energizing a small appliance particularly a small domestic appliance, from a battery or a rechargeable accumulator. A main control circuit (13) is supplied with energy directly from the supply voltage (at 12) and periodically controls the main switching element. A starting control circuit (16) is fed directly and exclusively from the energy source and periodically controls the starting switching element (15) so that is switching periods are shorter than those of the main switching. The starting control circuit, and thus the starting switching element, are switched off when the supply voltage reaches a predetermined value.

Abstract: The shank (3) of the rivet (1) has an inside thread. The shank also has a flat head (5) with two diametrically opposed radial notches (7). A spanner (9) has a circular opening with two diametrically opposed internal radial projections and fits over the head of the rivet. A bolt or screw (15) is screwed into the rivet and as it is tightened, with the spanner engaged to prevent rotation, the shank is pulled in axially. The shank is thus expanded and the rivet becomes assembled to the sheet.

Abstract: A pacemaker has means for producing first and second signals one of which changes rapidly in response to changes in exercise level but may inaccurately represent the appropriate pacing rate. Such signal may be derived from a vibration sensor. The second signal accurately represents the required pacing rate but changes slowly in response to exercise level and may represent any of a number of different physiological variables, such as respiratory rate. The signals may be derived from the same or separate sensors. A control circuit provides a pacing rate appropriate to resting conditions if the first signal has a value less than a threshold regardless of the value of the second signal. The pacing rate is elevated to a predetermined level, such as 95 beats/min, if the first signal exceeds the threshold but the second signal has a value indicative of a pacing rate less than the predetermined level. The pacing rate is further elevated to substantially equal that indicated by the value of the second signal when   the first signal exceeds the threshold and the second signal indicates a rate higher than the predetermined rate.

Abstract: A method of forming an organic thin film includes developing organic molecules having a hydrophilic por­tion and a hydrophobic portion on a water surface (w), and compressing the organic molecules thereby to form a monomolecular layer (11) of a predetermined surface pressure. The monomolecular layer (11) is brought into contact with a given substrate (12). Then, the sub­strate (12) to which the monomolecular layer (11) is adhered, is pulled at such a rate that the surface pressure is not substantially lowered, thus transferring the monomolecular layer (11) onto the substrate (12).

Title: Data-processing apparatus including a cache memory
Inventor: COLE TERENCE MICHAEL
IPC: G06F12/08
Filed: 1989-08-04
Abstract: A data processing unit accesses data in a cache, by means of a virtual address, If the data is not in the cache, the virtual address is translated, by means of a memory management unit (MMU), into a physical address for accessing the main memory. The MMU can also access the cache, by means of a physical address, to retrieve page table entries held in the cache. This avoids the need for a main memory access to retrieve the page table entries, and hence speeds up the address translation operation. The physically addressed entries in the cache are tagged with a reserved context number to distinguish them from the virtually addressed data.

Abstract: The system and method for detecting abnormalities in infusion of parenteral fluid involves producing perturbation of fluid flow by varying the flow rate of the fluid with respect to an equilibrium flow rate, measuring the pressure level, and measuring the pressure of the fluid over a period of time, to determine equilibrium pressure and a pressure response of the fluid to the perturbation, determining an integral of the difference between the equilibrium pressure and the pressure response, determining resistance to fluid flow, determining a second integral of the difference between the pressure response and equilibrium pressure multiplied by time, and determining compliance by dividing the second integral by the first integral. Resistance and compliance values are displayed, and an alarm is generated when the resistance or compliance parameters fall outside of reference ranges.

Abstract: A generally T-shaped gate (34) is formed by electron beam irradiation of a multilevel resist structure (20) on a substrate (12). The resist structure (20) has an upper layer (24) which is more sensitive to the electron beam than a lower layer (22) thereof. A generally T-shaped opening (30) is formed in the resist structure (20) by etching of the irradiated areas. An electrically conductive metal is deposited to fill the opening and thereby form a T-shaped gate (34) on the substrate (12). After the resist layer structure (20) and metal deposited thereon is removed, a masking layer (40) is formed on the substrate (12) around the gate (34), having an opening therethrough which is aligned with and wider than the cross section of the gate (34), and defining first and second lateral spacings (52, 54) between opposite extremities of the cross section and adjacent edges of the opening. Deposition of an electrically conductive metal forms source and drain metallizations (48,50) on the substrate (12) on areas underlying the first and lateral spacings (52, 54) respectively. The metallizations (48, 50) are self-aligned to the gate (34) and separated therefrom by the masking effect of the gate (34) during the metal deposition. The gate (34') may have an asymmetrical top section (34b') which provides a larger spacing between the gate (34') and source metallization (48) to increase the breakdown voltage of the device. Insulative oxide sidewalls (38) may be formed on the gate.

Abstract: A potential transmission-access failing in the IEEE 802.6 protocol is remedied by the use of terminals that sense the activity level on the interconnecting communications lines. In response to conditions that may give rise to such a failing, each terminal throttles its own transmission rate to improve the transmission capacity allocation of the protocol. In one embodiment, the terminal that transmits over more than half of the slots in the round trip delay simply throttles itself to one half the slots when it detects that another is transmitting or is wishing to transmit. In another embodiment, even a terminal that is transmitting over fewer than half the slots in the round trip delay determines the number of unoccupied slots and throttles itself to transmit over not more than half of the number of available slots. In still another embodiment, a terminal wishing to transmit many packets casts a number of reservation bits onto the transmission channel to insure for itself some transmission capacity. The number of reservation bits sent is equal to a fraction of the available slots. In yet another embodiment, each terminal throttles itself to take no more than a specified fraction of the remaining transmission capacity.

Abstract: A method for fabricating a solid electrolytic capacitor is described, in which a solid electrolyte is made of a conductive polymer layer (11) and is formed on a conductive inorganic layer (4) which is formed on a metallic foil (1) through a dielectric film (3). For the formation of the conductive polymer layer (11), while an external electrode (10) is not directly contacted with the conductive inorganic layer (4), the electrolytic polymerization reaction of a polymerizable monomer in an electrolytic solution (13) is carried out. For this purpose, the external electrode (10) may be covered with a conductive polymer film (11) at the contact portion. Alternatively, the external electrode (10) may be moved from one position to another or may be kept apart from the conductive inorganic layer (4) during the electrolytic polymerization reaction.

Abstract: 2.1 A process is described for producing soot filter candles which have a crosswound yarn as filter material, in which high temperature- resistant yarn composed of fine monofilaments is roughened by means of yarn twist, so that the filter candles can be used as soot filters in the exhaust gas stream of an internal combustion engine. The process should proceed as simply as possible and should provide a roughened yarn which ensures the required filter action. 2.2 According to the process, prior to winding, the bundles of fibres of the yarn are forced open by pulling the yarn under tension over a moving rough surface, the direction of motion of the rough surface differing from the direction of motion of the yarn and the angle between the direction of motion of the rough surface and the direction of motion of the yarn in the area of contact of the yarn with the rough surface being determined in relation to the twisting of the yarn. 2.3 Production of soot filter candles having a roughened high temperature-resistant yarn composed of fine monofilaments. <IMAGE>
