Abstract: IMPROVED MULTIFOLD CROSS-CORRELATION FOR  BOREHOLE SIGNALS                             Abstract Methods and apparatuses are described for improving the cross-correlation of a plurality of signals derived in an investigation of a borehole.  The technique involves the testing of signs of samples employed in forming a cross-product during a cross-correlation.  Sign conditions representa-tive of a good match are so recognized and the resulting cross-product modified if needed for constructive contribution to the cross-corralation.  Sign conditions indicative of a lack of correspondence between samples can also be detected so that cross-products from such samples can be prevented from adding to correlation peaks when an even number of negative samples are present.  Several embodiments are described.

Abstract: ABSTRACT OF DISCLOSURE: A motor-fan unit for a wet pick-up type of vacuum cleaner comprising a fan section and a separately ventilated motor section.  A motor-end bracket in the motor housing structure serves as a common end wall  with the fan section and carries a bearing for the common shaft of the motor and fan.  A baffle carried by the motor-end bracket within the fan section has an apertured central portion, at least partly enclosing the bearing, to provide a passage way for high velocity air sealing the bearing from detergent-containing cleaning liquid entrained in working air drawn into the fan section.  A normally closed check valve at an inlet to the sealing air passageway inhibits back-flow of either air or liquid through the inlet but permits such sealing air to serve as cooling air when the entrance of working air into the fan section is impeded.

Abstract: ABSTRACT OF THE DISCLOSURE In fabricating an optical fiber preform, a synthesizing torch is inclined by 10° to 60° with respect to the rotation axis of a seed rod.  Moving the rod while rotating it, a glass raw material gas and a flame forming gas are blown out individually from the torch to synthesize glass particles which are deposited onto one end of the rod, so that a cylindrical porous preform is grown in the direction of the rotation axis of the rod.  Then the porous preform is heated at a high temperature to vitrify the porous preform into a transparent optical fiber preform.          At least one exhaust port is disposed with a distance of 1 mm to 50 mm from the periphery of the porous preform and in the vicinity of the growing surface of the porous preform.  In fabricating the porous preform the outer diameter fluctuation is small, and the preform is formed stably without formation of crack on the periphery of the preform.  The growing speed is improved easily.

ABSTRACT OF THE DISCLOSURE           An air gun firing sensor apparatus and system are provided for determining the instant of firing of an air gun by sensing pressure changes within the air gun when it is being fired.  A pressure-change-sensitive trans-ducer assembly is inserted into a socket in the housing of a solenoid-controlled valve of an air gun with a passage from the air gun communicating with the transducer for transmitting to the transducer a pressure surge occurring within the air gun whenever it is fired.  The transducer assembly has a cylindrical casing with a head mounted at one end.  The head includes a plurality of spaced recesses which are adapted to communicate with the passage leading from the air gun.  A pressure-sensitive transducer is mounted in the head wall between and adjacent to these recesses, in effect being sandwiched in the head wall between these recesses with the transducer extending parallel to the recesses, whereby a pressure surge occurring simultaneously in the recesses is transmitted  through the head wall to the transducers, being transmitted in a direction transverse to the axes of the respective recesses.  Accordingly, a pressure pulse produced by the firing of the air gun squeezes the portions of the head wall between these recesses inwardly applying pressure to the transducer which generates a voltage indicative of the instant of firing of the air gun being monitored.

Abstract: Abstract A power supply provides direct current to electrodes attached to a patient.  The positive electrode is at least partially silver and releases silver ions as a result of the electric current.  Silver ions have known bactericidal properties and may be used to treat infected living tissue. Tissue may, hwever, be damaged by voltages in excess of 1.1 volts.  Accordingly, the power supply has two modes. under normal conditions the power supply has a constant current output.  If the voltage between the electrodes reaches a reference voltage on not more than 1.1 volt, the output is changed to a constant voltage mode, abruptly limiting the output voltage.  Indicating means may be incorporated in the supply.

The device comprises an elongated, tubular, intermediate casing of a magnetic material, such as a ferromagnetic material, having an elongated magnet received therein.  The magnet has at least two axially spaced poles, and preferably is magne-tizea along its longitudinal axis such that it comprises two adjacent magnetic domains having opposing magnetic moments such that there exist at least three longitudinally spaced apart sections of alternate North and South polarity.  An inner casing of non-magnetic material, such as copper, en-cases the magnet and includes open tubular end portions ex-tending beyond opposite ends of the magnet and having inner and outer surfaces extending longitudinally with respect thereto.  A pair of non-magnetic end fittings are connected to opposite ends of the intermediate casing and include re-cesses in which are received the respective opposite tubular end portions of the inner casing so as to space the inner casing from the intermediate casing thereby forming an annular treatment chamber therebetween.  In a modified form of the device, the recesses are replaced by tapered passages adapted to seat the tubular ends of the inner casing and prevent movement between the inner casing and the end fittings.  Aper-tures are provided at each of the tubular end portions so as to form fluid flow paths from within the tubular end portions to the treatment chamber.  The tubular end portions may be crimped or otherwise deformed to form inwardly projecting locking projections adapted to prevent axial movement between the magnet and. the inner casing.

Abstract: SEMICONDUCTOR MEMORY DEVICE              ABSTRACT OF THE DISCLOSURE     Disclosed is a semiconductor memory device which comprises a sense amplifier formed on a semiconductor substrate, paired bit lines connected to the sense amplifier and memory cells connected to the bit lines wherein a predetermined bias voltage is applied to the semiconductor substrate and the reading operation is performed by amplifying by the sense amplifier a voltage difference caused between the paired bit lines owing to access to the memory cells.  This semiconductor memory device is characterized in that a voltage of a phase reverse to a noise to the bias voltage applied to the semiconductor substrate is applied to the semiconductor substrate through an electrostatic capacitance formed on the semiconductor substrate to cancel the noise.  By virtue of this characteristic feature, influences of such noises can be eliminated in the semiconductor memory device of the present invention.
