Abstract: A submersible apparatus (10) which can be fully submerged in a liquid medium, includes: a sealed hollow body (12) having a longitudinal main axis (A); at least one driving member (14, 36, 52) for moving the apparatus (10) horizontally and/or vertically, which can co-operate with the medium in which the apparatus (10) is submerged and which can move in relation to the hollow body (12) through an opening (22, 44, 56) provided in the wall of the body (12); and elements (18, 40, 64) for actuating the driving member (14, 36, 52), which are disposed inside the hollow body (12). The invention is characterized in that the opening (22, 44, 56) is sealed by a flexible membrane (24, 50, 58) which can deform and co-operate with the driving member (14, 36, 52) as the driving member (14, 36, 52) moves through the opening in order to move the apparatus (10).

Abstract: Suction pile installation method comprising the steps of lowering a suction pile to the sea bed, while keeping a top end substantially closed providing openings in the suction pile near a lower end, the interior of the suction pile being in open fluid communication with the exterior via the openings, dropping the pile onto the sea bed, while allowing air to escape from the pile via said openings, and allowing the suction pile to penetrate into the sea bed driven substantially by its weight over such a distance that the openings become closed from the exterior, and pumping air from the suction pile for driving the pile further into the sea bed.

Abstract: A device for exploration of the cardiovascular system of human or animal bodies includes a generally transparent blind tube delimiting a cavity in which can be disposed an optical display device, the open end of the tube being shaped to be ensleeved axially in a sealed manner in the passage of an artery or of a vein having first been at least partially sectioned such that the cavity of the tube in the interior of the artery or of the vein form a common chamber at least partially closeable by a cardiac valve. The tube, maintained in ensleeved position by a suitable securement member, includes at least one supplemental opening for the introduction into the cavity of the tube of a physiological liquid under pressure.

Abstract: A voice-input document creation system which reduces correction times to a wrongly-recognized input to ensure input efficiency. The system has a determination means for comparing the feature content of a newest voice input extracted by a feature extracting module with a feature content of an immediately preceding voice input to determine if the newest voice input is a correction to the immediately preceding voice input. When a first-time correction is received, the system displays a list of all output candidates for the immediately preceding voice input stored in a second memory. When a second-time correction is received, the system stores the output candidates for the newest voice input into a third memory and, at the same time, displays the output candidates; at this time, the system neither displays nor stores in the third memory those output candidates displayed upon the first-time correction.

Abstract: An apparatus for loading battery plate groups into a battery box. The apparatus includes a compression frame which includes a number of relative movable walls and stops for gripping and retaining battery groups. The wall carry guide shins for projecting into respective cells in a battery box and guide the groups into the cells as they are pushed by a pusher. The movable nature of the walls allow the groups to be loaded into frame, when it is in released position. The walls can then be drawn together compressing the groups and retaining them in a compressed state as they are loaded.

Abstract: A logic circuit which is driven at low voltage and operates at high speed and low power consumption is provided. Substrate potentials of P and N type transistors MP11 and MN11 constituting an inverter are controlled correspondingly to a stable state of the inverter. In a stable state of the inverter in which the P type transistor MP11 is ON, the substrate potential of the N type transistor MN11 which is OFF is lowered to ground potential or lower and, in a stable state of the inverter in which the N type transistor MN11 is ON, the substrate potential of the P type transistor MP11 which is OFF is raised to a power source potential or higher.

Abstract: A matching circuit is formed by a series inductor, a parallel capacitor, a drain bias circuit, and a DC-blocking capacitor for the purpose of impedance matching. A capacitor having a capacitance that is dependent upon the bias voltage is used as the parallel capacitor. This can be, for example, a material such as a (Ba.sub.X Sr.sub.1-X)TiO.sub.3 thin-film, which exhibits a capacitance having a bias voltage dependency. Because this thin-film capacitor exhibits polarization by an electrical field, its capacitance is the largest with a bias of 0 volts, and is reduced to approximately 50% as the bias voltage is increased. By using this capacitor in a matching circuit, it is possible to change the matching condition as the output power is increased, that is, as the voltage applied to the capacitor is increased.

Abstract: A mold for making an optical lens and formed of two molding shells disposed on edge and an annular closure member around their periphery and defining with them a molding cavity. To fill the mold a molding material is introduced into the molding cavity through a casting opening formed for this purpose in the closure member. The casting opening is in the lower part of the molding cavity.

Abstract: The invention relates to an auxiliary unit included in a control arrangement for an internal combustion engine. An NTC-resistor (6) which is subjected to the effect of engine temperature of engine cooling-water temperature, is connected to a control system (5) which monitors the resistance of the NTC-resistor (6), this resistance varying with engine temperature, and utilizes this variation in resistance to change temperature-dependent control parameters for engine operation. The auxiliary control unit is connected to NTC-resistor (6). The auxiliary control unit applies an elevated voltage across the NTC-resistor over a predetermined period of time after an engine cold start, so as to deceive the control system (5) in indicating that the resistor is colder than it actually is.

Abstract: Filtering apparatus 1 comprises a generally cylindrical lattice frame 6, for supporting a filter bag 3, and an annular support member 13 from which extend rods 12 connected together by channel-shaped straps 14, 24 or 34. The technical problem is to provide a frame for a filter which is compact for transport to the erecting site yet quick and straight-forward to erect. Cut-outs 18 are formed in the side walls 14b of the straps 14, 24 or 34 and the support member 13 is fashioned from a flat strip of material. For transport the rods 12 are located in the cut-outs 18 and spot-welded to the straps 14, 24 or 34 and to support member 13 while the straps 14, 24 or 34 and the support member 13 are laid out flat; several such flat assemblages may then be stacked on one another. At the erecting site the support member 13 and straps 14, 24 or 34 are bent round into shape, the straps 14, 24 or 34 being bent in the region of each cut-out 18 so as to deform each cut-out 18 to retain the corresponding rod 12 therein.
