Abstract: An oil filter is provided being of the type which comprises a housing opened at one end thereof, a cylindrical first separator unit disposed in the housing for removing solid contaminants from an oil introduced into the housing, and a second separator unit disposed within the first separator unit for removing gaseous contaminants from the oil that has passed through the first separator unit, the second separator unit including a cylindrical casing having at least one inlet passage, a funnel-shaped cyclone fitted in the casing to define a chamber for a vortical flow of the oil introduced therein to thereby separate gas-rich oil and a removal pipe extending into the chamber along an axial center thereof for discharging the gas-rich oil. The improvement resides in that the casing has a head portion defined by a circumferential wall having an increased thickness, and that the inlet comprises an inlet passage formed through the circumferential wall and inclined relative to a radial direction of the head portion to have a greater length than the thickness to the circumferential wall. The inclined inlet passage having significant length contributes to an enhancement of the vortical flow to be subsequently generated in the chamber.

Abstract: A cable coupling, particularly for data buses, includes a transformer (23) and resistors (28, 29) to which the cables (1, 2, 3) are directly wired. The components and all electrical connections are enclosed in a heat shrinkable tubing (35) or sleeve filled with liquid encapsulant (34). Upon application of heat, the tubing shrinks causing the encapsulant (34) to fill all voids between components. The encapsulant (34) is then cured to provide an uncased coupling assembly which protects the components and electrical connections from beakage, while eliminating the need for a separate rigid housing. An overbraided shield and environmental seal may subsequently be added to provide further protection for the coupling.

Abstract: A copper film coated substrate includes a substrate and a copper film formed on a surface of the substrate. The copper film has an X-ray diffraction intensity of 2.0 cps/nm or more per unit film thickness at a crystal orientation (111) face of the copper film. A crystal orientation of a copper thin film is controlled by irradiating a surface of a substrate with inert gas ions before forming a copper thin film on the substrate by a physical vapor deposition process. A copper thin film is formed by irradiating a surface of a substrate with ions, and depositing a copper thin film on the irradiated substrate. In the ion irradiating step, an ion irradiation energy for a dosage of the irradiated ions is controlled, so that crystal is greatly grown to be orientated in a direction of copper (111) face with a less dosage of the irradiated ions.

Abstract: A method of correcting data on the positions of chip regions (2) defined on a semiconductor wafer (1), which data is recorded on a map along with data on characteristics of semiconductor devices formed in the chip regions. This method is intended to enable the map to be referred to from positional information shown on the chips separated from the wafer. A chip region at which the center of the map is located is obtained on the basis of coordinate values provided for chip regions on the map in a characteristic test process, and the coordinates on the map are converted so that the coordinates of this chip region are (0, 0). With respect to each of the chip regions (e.g. 2A₁) belonging to the fourth quadrant of an orthogonal coordinate system (XY) having an origin at the center of the map, a verification is made as to whether a corresponding chip exists in the other quadrants. If no corresponding chip exists, coordinates for the corresponding chip (e.g. 2a₁) in the other quadrants are written on the map. It is thereby possible for deficient chips not selected as characteristic measurement objects to have coordinates written on the map.

Abstract: A sheet processing apparatus mountable on the side of a copying machine body processes sheets discharged from. The apparatus includes a sheet supplier (30) for supplying sheets received from the copying machine body; a sheet discharger (31); a first transport route (40) connecting the sheet supplier (30) and discharger (31), and a sheet-stamping mechanism (33) disposed opposite the sheet-bearing surface of the first transport route (40). Further included is a second transport route (41), diverging from and extending below the first transport route (40), which feeds sheets to a punching mechanism (34) disposed opposite it; a transport drive (42, 43) providing controlled transport of sheets in each transport route (40, 41); and a process timing control unit.

The timing of the processes is controlled according to set conditions. Transport within the reduced-dimension apparatus is such that wherein holes are punched into a sheet in the punching mechanism (34), drive in a latter-stage unit such as a sorter mounted at the discharger (31) need only be halted, a reversing capability or the like thereof thus being unnecessary.

Abstract: A semiconductor laser device has a current confinement structure of a thyristor structure (1,5,6,7) at both sides of an active region (3), and at least a p-n junction in the current confinement structure, to which a forward bias voltage is applied during laser operation, is short-circuited by a metal layer (11) or a low resistance material layer. Therefore, injection of holes from the p layer (7) into the n layer (6), which are short-circuited during the laser operation, is suppressed, whereby the current confinement structure is not likely to be turned on. In addition, the current practically flowing through the blocking layer is decreased. At a result, a current blocking effect is largely improved, preventing reduction in the laser output power and reduction in the linearity of light output vs. current characteristic.
