Abstract: The invention relates to a process for dividing up and recovering the individual materials from old cables. For this purpose, the cable mixture is sorted into individual constituents and cut to size, the outer plastic sheath is removed by being slit open, and the individual cores are fed to a disk comminuter. It is essential, at the same time, that the disk comminuter should cut up the individual plastic-sheathed cables or the cable composed of several individual cables into short cable pieces of a length of 3 to 10 mm in a salami-like manner. Because the pieces are very short, the short cable pins are separated from the plastic ring arranged round them on a following vibrating screen.

Abstract: A low-NOx boiler comprises a burner for burning gaseous fuel, heat transfer pipes (117) heating water by combustion heat of the burner to generate steam and having a passage (131) through which water flows, a steam drum (128) communicating with the heat transfer pipe and accumulating the steam from the heat transfer pipe, and an exhaust gas duct (114) located in the furnace to exhaust combustion gas generated by combustion of gaseous fuel outside of the boiler. The boiler further comprises unburnt gas burner (126) in the exhaust gas duct (114) for burning unburnt content in the combustion gas flowing in the duct. The unburnt gas burner includes a nozzle (2) for inject­ing premixture flow of fuel and combustion air and flame holding plate (1) located near the downstream side of the outlet of the nozzle to interrupt the premixture flow to form a circulating flow on downstream side of the flame holding plate. As gaseous fuel and air are mixed in advance and a flame is formed, the flame length can be shortened. Furthermore, the flame holding plate enables to reduce NOx generated. Unburnt gas burner pro`vided in the exhaust gas duct makes it possible to notably reduce the concentration of NOx discharged to the outside of the system.

Abstract: Spaced-apart regions (2) each having top (2a) and side walls (2b) meeting at an edge (20) are defined on a surface (1a) of a substructure (1) forming part of the device. A layer (3) of insulating material is provided over the said surface (1a) and regions (2), so that the insulating material is provided preferentially at the said edges (20) of the regions (2) to form adjacent the said edges (20) portions (31) of the insulating material which overhang the underlying insulating material (32) provided on the said surface (1a). The insulating material layer (3) is then etched anisotropically to expose the top walls (2a). During the anisotropic etching the overhanging portions (31) initially mask the underlying insulating material provided on the said surface (1a) so that the etching of the underlying insulating material is controlled by the etching away of the overhanging portions (31) and when the top walls (2a) are exposed relatively gently sloping spacers or portions (30) of the insulating material remain on the side walls (2b). A further insulating material layer (4) may then be provided over the structure.

Abstract: A system is disclosed for measuring the partial pressure of a gas, and in particular of carbon dioxide (p CO ). The system uses an electrolytic solution of weak ionic strenght which is circulated between an ion-selective electrode and a membrane permeable to gases but not to the ions and substantially distant from the electrode. The partial pressure of the gas is measured after a fraction of the electrolytic solution has been permeated by the gas present in the sample and subsequently has been transferred on the sensible portion of the electrode.

Abstract: The semiconductor device has a lower junction termination which is brought to the upper surface. It is fabricated by diffusing first and second (22) regions of a first conductivity type (N) into an upper surface (18) of an epitaxial layer (16) of a second conductivity type (P) disposed on a substrate (14), and forming a groove (60) having sloped sidewalls in the upper surface such that the groove extends through the second diffused region (22), the epitaxial layer (16) and into the substrate (14). A thin layer (64) of impurities of the first conductivity type (N) is implanted into the sidewalls, and the impurities are electrically activated to form a low resistivity path that connects the substrate to the second diffused region. Subsequently, the semiconductor device may be separated from the wafer by cutting the wafer at the groove. The manufacturing process enables substantially complete fabrication of a plurality of devices while still in wafer form, thereby avoiding the inconvenience of processing individual dice.

Abstract: An encoder encodes input data into codes and outputs the codes. Quantities of the codes which are outputted from the encoder during respective first predetermined periods are predicted. The predicted amounts of the output codes are added to derive a sum of the predicted amounts of the output codes which is generated during each second predetermined period longer than each of the first periods. An actual amount of the output codes from the encoder is controlled in accordance with the derived sum. Differences between the predicted amounts of the output codes and the actual amounts of the output codes which are generated during the respective first periods are sequentially generated. The differences are accumulated into an accumulated value. The actual amount of the output codes from the encoder is controlled in accordance with the accumulated value. The actual amount of the codes which are outputted from the encoder during each second period can be held equal to or smaller than a predetermined amount.
