Abstract: The present invention relates to an external magnetic field inverting apparatus for a magneto-optical disc apparatus in which a permanent magnet (15) is used as external magnetic field generating means and a winding (25) is located so that upon supply of a current to that winding the said permanent magnet (15) can be rotated. A magnetic member (30) is located near the said permanent magnet (15) in such a manner that a magnetic flux generated from said winding (25) crosses that permanent magnet (15) with an inclination of a pretermined angle relative to an axis perpendicular to the longitudinal axis of the permanent magnet (15). Thereby the apparatus according to the invention can be reduced in cost, increased in reliability and miniaturized in size.

Abstract: A wiring layer structure of a resin sealed semiconductor integrated circuit, which is free from slide of wiring layer during heat cycle test, is disclosed. The slide is prevented by making an effective width of the wiring layer smaller by means of slits (S) formed in the wiring layer (208A-1,208A-2,208A-3). A reduction of area to be occupied by the wiring layer is realized by reducing a total width of the wiring layers by increasing the density of slits with increase of a distance from a corner of the chip.

Abstract: A combined optical and capacitive absolute positioning encoding system uses a plurality of metallized strips deposited onto a glass scale substrate. A movable transceiver is positioned adjacent to the scale. The transceiver generates interrogating electrical and optical signals which interact with the scale. The movable transceiver also carries with it receiver mechanisms for receiving the signals after interaction with the scale. Signal processing electronics are provided to determine the relative positions of the scale and transceiver by comparing the transmitted, interrogating signals with the received signals. The system is able to determine the relative positions of the scale and transceiver even if power to the system is interrupted, or if the scale and transceiver are moved relative to one another very rapidly.

Abstract: A signal source (SV) applies a signal having a fixed low frequency modulation added thereto through a capacitor (CS) to a line (L) to which is connected a first clamping means comprising a first voltage controlled current amplifier or transconductor (A1), a second input of which receives a reference voltage (VR1). The transconductor (A1) output is applied through a first switch means (S1) to the line (L) which switch means (S1) is periodically closed during a defined clamp period in the signal. A filter (BP) is also connected to the line (L) having a pass band centred on the frequency of the modulation which periodically samples the signal during the clamp period. The filter (BP) output is applied to a second transconductor (A2) having a transconductance greater than that of the first transconductor (A1) a second input of which receives a second reference voltage (VR2). The output of the second transconductance (A2) is applied through second switch means (S2) to the line L periodically closed during a defined period in said signal other than the clamp signal.

Abstract: Ceramics material are not resistant to tensile force, though they are resistant to compression force. Therefore, ceramics materials, when used as the material of a commutator of an electric rotary machine, tends to be cracked and broken due to tensile stress generated in the inner peripheral portion of the commutator when the latter is press-fitted on the rotor shaft of the machine. the invention is aimed at obviating the above-described problem, so as to make it possible to produce a sliding current collector of an electric rotary machine from a ceramics material. To this end, according to the invention, an annular gap is formed between the inner peripheral surface of the ceramics commutator and the other peripheral surface of the rotary shaft and the gap is filled with a resin such as a thermosetting resin which is then thermally set to form a resin layer by which the commutator is bonded to the rotor shaft. The resin layer effectively absorbs any tensile stress which may otherwise be caused in the inner peripheral portion of the commutator due to, for example, thermal expansion of the rotor shaft. It is thus possible to securely fix the commutator to the rotor shaft without risk of cracking or damaging of the commutator.

Abstract: First and second resistors are connected in series with a Zener diode between first and second points of operating potential. The base-to-emitter of an NPN transistor is connected across the first resistor to sense the current through the series path. The collector-to-emitter of a PNP transistor is connected across the second transistor, whereby when the PNP transistor is turned-on hard and into saturation, the voltage drop across the second transistor decreases. The collector of the NPN transistor is connected to the base of the PNP transistor, whereby when an overvoltage condition exists and the Zener diode breaks down, the two transistors are driven regeneratively and form a latch and the operating point of the circuit is shifted.

Abstract: A tone detection method for a telephone subset to detect tones in the presence of noise and speech. According to the method the period of an input signal containing the valid tone is measured at a fixed sample rate (say 10 ms). The measured periods are compared to that expected of a valid tone and a pass/fail decision is made for each sample and stored in a buffer whose length is chosen to be longer than a complete cadence cycle of the valid tone (say 1 second). By examining the buffer it is possible to calculate a percentage pass rate for any period. If the pass rate is above a predetermined threshold then a valid tone is present.

Abstract: An optical recording medium having on a substrate an optical recording film and an inorganic dielectric film containing a target element of a metal or metalloid, such as Si or Ge, is produced by forming the inorganic dielectric film by subjecting a sputtering target comprising a crystal of the target element to DC sputtering in a reactive gas atmosphere. Abnormal discharge leading to inferior products and a lower productivity is suppressed by constituting the sputtering target to have a sputtering surface conforming to a lattice plane of the crystal free from a void allowing intrusion of an atom, ion or radical originating from the reactive gas into the unit lattice. In case of an Si single crystal having a diamond structure, the sputtering surface is preferably conformed to a lattice plane represented by Miller indices (1,0,0) or (1,1,1). The sputtering target is preferably provided with a chamfer adjacent to the sputtering surface.

Abstract: An anchor for attaching an object to a bone or bone-like structure, and a method for using the same. The anchor includes a body and a plurality of barbs located in axially aligned, circumferentially spaced relation to each other about the body. The barbs have a normal configuration wherein they extend rearwardly and radially outwardly from the anchor body to outer ends which are normally located outside a longitudinal projection of the largest geometric cross-section of the body transverse to its longitudinal axis. The barbs may be elastically deformed to a configuration wherein they are located substantially within the longitudinal projection. A transverse bore extends through the front portion of the anchor for engagement by a length of cord-like material. Also, an opening oriented perpendicularly to the bore extends through a flattened rear portion of the anchor. Further, a longitudinal slot aligned with the opening connects the front end of the anchor body to the opening. This slot minimizes the force necessary to pull the anchor into its desired position relative to the bone and allows the anchor to be disconnected from the object and removed after deployment. The method includes the steps of threading a cord-like material through the bore in the front portion of the anchor; connecting the object to the rear portion of the anchor, either directly or by a second length of cord-like material; threading the cord-like material attached to the front portion of the anchor through a hole in the bone; pulling the anchor into or through the hole to a position slightly beyond its desired anchoring location; and exerting a pulling force on the object so as to set the barbs of the anchor into the bone.
