Patent JP-2666958-B2 (JP)
IPC: H01H33/02
Filed: 1988-05-02
Granted: 1997-10-22
Abstract: In a metal-clad, gas-filled, multiphase high-voltage switch gear, having a partition (12) between the busbar chamber (21) and the switch chamber (14), the connection between the two chambers (14, 21) takes place via ducts (13) inserted diagonally in the partition (12), which ducts (13) are arranged in the one direction in the spacing of the busbars (1) and, in the other direction, in the spacing of the poles (6) of the circuit breaker or load isolator (9). As a result, straight-line, crossing-free connections are possible in the busbar chamber (21), between each busbar (1) and the associated duct (13), via the respective isolating or three-position switch (8), while the connecting lines (15a, b, c) in the switch chamber (14) run to the poles (6) in mutually parallel planes, once again without crossing. 
<??>Apart from minimising the switch gear dimensions and increasing the electrical strength as a result of the diagonal arrangement in the busbar chamber (21), in conjunction with a square housing (20), the installation of earthed separating walls (22, 32) between the phases in the two chambers (14, 21) allows effective reinforcement of the outer walls (17) and, above all, the partition (12) to be achieved. Likewise, in the event of a fault, phase shorts with high current arcs are prevented. The stated advantages can also be used in the case of separated multiple busbar systems.

Patent JP-S648054-B2 (JP)
IPC: C22B1/24
Filed: 1983-06-21
Abstract: The invention relates to a process and an apparatus for preparing binder-free hot-briquets for smelting purposes from ferrous pyrophorous, finely divided solids, such as dry steelmaking-filter dust or slightly granular sponge iron from direct-reduction plants. Before the briquetting stage, oxidizing gas is blown at a temperature of more than 200 DEG  C. through the finely divided dry solid containing more than 4% by weight of metallic resin. The flow rate of this gas is controlled in such a way that oxidation of some of the metallic iron raises the temperature of the finely divided solid to 450 DEG  C. to 650 DEG  C. This is followed by hot-briquetting.

Abstract: An electroluminescent device includes a semiconductor layer (4) in the form of a thin dense polymer film comprising at least one conjugated polymer, a first contact layer (5) in contact with a first surface of the semiconductor layer, and a second contact layer (3) in contact with a second surface of the semiconductor layer. The polymer film (4) of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers that on applying an electric field between the first and second contact layers across the semiconductor layer so as to render the second contact layer positive relative to the first contact layer charge carriers are injected into the semiconductor layer and radiation is emitted from the semiconductor layer. The polymer film can be poly (p-phenyenevinylene) [PPV] of formula (I) wherein the phenylene ring may optionally carry one or more substituents each independently selected from alkyl (preferably methyl), alkoxy (preferably methoxy or ethoxy), halogen (preferably chlorine or bromine) or nitro. A method of manufacture of an electroluminescent device includes steps of depositing a thin layer of a precursor polymer onto a substrate and then heating the precursor polymer to a high temperature to form the conjugated polymer.

Abstract: In a dual bus microcomputer system using a cache memory and a cache controller, the timing requirements placed on non-cache memory components by the cache controller are more stringent than the timing requirements placed on the non-cache memory components by the microprocessor. A logic circuit operates on the cache write enable (CWE) signals, and delays those signals in the event of a cache read miss. Delaying the CWE signals relaxes the timing requirements placed on non-cache memory components and at the same time does not impact wait state parameters for read miss operations.

Abstract: The present invention is an improved process for purification of active heparinase and heparinase like enzymes from Gram negative organisms, in particular, Flavobacterium heparinum. The primary advantage of the process is the fact that is allows large scale processing and high yield of heparinase. The heparinase is released from the pariplasmic space of the organism by osmotic shock treatment, first into an osmotically stabilized medium, secondly into a non-stabilized medium having a pH of approximately pH 6.0 and 8.6 with subsequent release into a second non-stabilized medium containing approximately 0.15 M sodium chloride, followed by fractionation by cation exchange chromatography, and, optionally, electrophoresis or gel filtration chromatography. Two proteins having heparinase activity have been isolated, one having a molecular weight of approximately 42,000 Daltons and the other having a molecular weight of 65,000 to 75,000 Daltons. Also described is the construction of a library for screening for the genes encoding the proteins having heparinase activity and two assays for detecting organisms producing heparinase, either F. heparinum or genetically engineered organisms.

Abstract: PURPOSE:To quickly perform an air deflating operation by connecting a pump mechanism for discharging air to the outside to an air escape hole mounted on the wall portion of a cylinder. CONSTITUTION:In case of deflating air contained in oil fed into a cylinder 2, a clip 19 is detached to move a piston 8 to be pulled outward, and a gap 17 on the trailing end side is passed through a groove 21. At this time, the interior of a cylinder 6 gets to negative pressure, so that air bubbles in the cylinder 2 are discharged with oil through an air escape hole 5, the groove 21 and the gap 17 to the base of the cylinder 6. Subsequently, the piston 8 is pushed toward the base of the cylinder 6, so that air bubbles and oil in the cylinder 6 are discharged from a vent hole 9 through a discharge port 16 of a one-way valve 15 to the outside. Thus, air bubbles in the cylinder 2 are gradually discharged with oil to the outside by reciprocating the piston 8.

Abstract: In a method of positioning a workpiece holder (1) in a machine, provision is made for the workpiece holder (1) to be put into and fixed in a position approximately corresponding to the desired position and for its initial position to then be determined with the aid of at least two reference marks (22, 23) made on the workpiece holder (1). The workpieces (50, 51, 52, 53, 54) clamped in the workpiece holder (1) are measured at a measuring location specially equipped for this. The measuring data thus determined are transmitted to the machine. The effective position of the workpieces (50, 51, 52, 53, 54) on the machine can then be calculated from the position of the reference marks (22, 23). Furthermore, a workpiece holder (1) is proposed which has at least two reference marks (22, 23), arranged at a horizontal distance from one another, for detecting its position in the X- and Y-direction as well as its angular position about the Z-axis. By such a method and a workpiece holder (1) designed according to the invention, the position of the workpiece holder (1) in the clamped state can be determined more accurately than hitherto. In addition, such a workpiece holder (1) embodied without conventional centring elements is considerably less expensive to manufacture. <IMAGE>
