    摘要: A rotary head device having a rotary drum and a rotating motor within the rotary drum, with the stator of the motor being supported by a fixed arm attached to a fixed drum or to a fixed drum supporting member. The construction permits the manufacture of the rotary head device using the manufacturing equipment used for conventional rotary shaft type rotary head devices despite the rotary head device being a thin device. In this rotary head device the position of contact of a ground brush and a rotor can be set at the center of rotation or thereabouts, so despite it being a thin device, the sliding speed of the ground brush is low, and hence it is possible to prevent the abrasion of the ground brush and also to prevent increase of the rotative driving torque.

    摘要: A coating fault locating technique transmits a base electric signal from a power source to a buried metal pipe. A location of a coating fault in the buried pipe is detected by detecting a gradient of a changing magnetic field between two points spaced along the buried pipe. The gradient is detected based upon the output differential of at least one pair of search coils. The gradient is caused by a leakage of current that occurs at the coating fault. In particular, the at least one pair of search coils are provided in a mobile unit that is located above ground. The at least one pair of search coils are spaced apart from one another and have their axes arranged so as to have a low sensitivity to a magnetic field generated by the base electric signal running through the buried pipe. The at least one pair of coils are spaced apart from each other such that a line drawn between midpoints of the search coils' axes crosses a plane normal to the axis of the buried pipe. For example, the at least one pair of search coils are spaced from each other horizontally, with each coil arranged with its axis extending in a vertical plane. The data detected by the search coils in the mobile unit can be transmitted to a GPS system, which then generates a map identifying the locations of any detected coating faults.

    摘要: An electromagnetic pump comprising fluid operation chambers for discharging fluid to the outside; and electromagnet connected to an AC power source device for polarity switching for every half cycle of AC when energized; a permanent magent which moves together with the electromagnets; and a reciprocative shaft holding the permanent magnet, which reciprocates in the shaft direction when the electromagnet is energized. The width of a securement portion for the permanent magnet of the reciprocative shaft is relatively narrow compared to the other portions, and the permanent magnet consists of a pair of permanent magnet pieces bonded together by sandwiching the securement portion therebetween. The electromagnetic pump further comprises a fluid operation member for expanding or contracting the volume in the fluid operation chamber by the reciprocation movement of the reciprocative shaft so as to guide fluid out.

    摘要: A solenoid-operated reciprocating pump includes a casing having a cylinder with a central axis. A main shaft is disposed in and secured at one end to the casing in alignment with the central axis of the cylinder. A piston having a piston head is slidably fitted over the main shaft such that the piston head is disposed within the cylinder for axial motion. A coil spring extends between the piston and casing to bias the piston in a first axial direction and an armature radially extends from the outer periphery of the piston for interaction with an electromagnet disposed around the longitudinal periphery of the piston. The electromagnet attracts the armature and hence the piston in a second axial direction opposite from the first direction. On end of the coil spring is fixed to one of the piston or the casing and the other end of the spring is rotatably supported on the other of the piston or the casing by a spring retainer seated on a plurality of spherical balls which are in turn seated on said other of the piston or the casing means. The balls are positioned at equal distances radially from the central axis of the coil spring and at equal circumferential spacings around the axis.

    摘要: A rotary magnetic head cylinder device for use in a helical-scanning system video tape recorder has a projection provided on a tape running race of a stationary lower cylinder near a location at which a magnetic tape leaves from the lower cylinder. The projection is preferably integral with the tape running race and has a small area which is defined by a shoulder circumferentially extending identically with a tape guide shoulder contouring the lower edge of the tape running race and which spreads perpendicularly to the tape running race, and an upper surface coplanar with the top face of the lower cylinder, and a height defined by a protruded length radially outwardly toward the outer circumferential surface of the lower cylinder. The projection serves to reduce vibrations of the magnetic tape generated when the video head carried by the rotary upper cylinder leaves from the magnetic tape.

    摘要: An electromagnetic reciprocating pump which maintains the outlet pressure at a preset value comprising a pressure sensor for detecting the actual outlet pressure of the electromagnetic reciprocating pump and means to feedback control the frequency of the reciprocating motion and, if necessary, its stroke of the electromagnetic drive means based on the deviation from the preset outlet pressure of the actual outlet pressure. The reciprocating motion frequency control of the electromagnetic drive means may be done by modulating the frequency and amplitude of the half-wave AC current supplied to the electromagnetic drive means. With this, the control of the number of times of the reciprocating motion of the electromagnetic drive means can be carried out without changing the reciprocating motion stroke of the electromagnetic drive means.
