Abstract: A low-loss compact and a method for producing the compact are provided. A method for producing a compact by using coated soft magnetic powder that includes coated soft magnetic particles constituted by soft magnetic particles and insulating coatings coating outer peripheries of the soft magnetic particles includes a raw material preparation step and an irradiation step. In the raw material preparation step, a raw compact is prepared by press-forming coated soft magnetic powder. In the irradiation step, part of a surface of the raw compact is irradiated with a laser. Irradiating a part of a surface of a raw compact with laser increases the number of disrupted portions of conductive portions where constituent materials of the soft magnetic particles at the surface of the raw compact have become conductive to each other, and the loss of the compact can be decreased.

The grommet body has a first cylindrical portion disposed at one side, a second cylindrical portion disposed at the other end and a third cylindrical portion disposed within the first cylindrical portion. The first cylindrical portion has a maximum inner diameter larger than a maximum inner diameter of the second cylindrical portion. The third cylindrical portion projects to the one side from an inner peripheral surface of the first cylindrical portion. The inner peripheral surface of the second cylindrical portion and the inner peripheral surface of the third cylindrical portion defines a harness insertion portion in which a wire harness is inserted from one side to the other side. The inner peripheral surface of the first cylindrical portion and the outer peripheral surface of the third cylindrical portion defines an annular space for allowing the first cylindrical portion to elastically deform.

Abstract: A connector-mounting structure for mounting a pair of mating connectors for connecting wires conducting electrical current comprises a bracket which is mounted to a member of an automobile, for example. A first connector which houses a plurality of first terminals with wires connected thereto is placed in the bracket. A second connector which houses a plurality of second terminals with wires connected thereto is connected to the first connector. Pivot pins, slots or slot and a hole, and stopping members are formed in the bracket and first connector so as to hold the first connector at a first position for connecting the second connector to the first connector and to retain the first connector at a second position to which the first connector is moved from the first position by turning.

Abstract: A tying band cluster consists of a plurality of tying bands connected in series, end to end, in longitudinal direction. Each of the tying bands has a head portion, a projecting piece formed at one end of the head portion, and a major portion of a band body formed at the other end of the head portion. When a tying band is formed, the projecting piece of the current tying band is fused with the free end of the major portion of the previous tying band. Because the major portion of the previous tying band is left in the molding dies when the next tying band is formed, the major portion of the previous tying band is kept heated and can therefore be fused completely with the projecting piece of the tying band currently being formed. This ensures a solid connection between the tying bands.

Abstract: The invention provides an improved method for forming a cover layer over a joint of electrical wires. Portions of insulation layers of wires to be joined are stripped and the bared conductors of the wires assembled in a desired configuration to form a joint. The joint is placed in a transparent mold and the mold is filled with a photosetting resin. Radiation of an appropriate wavelength is then passed through the mold to harden the resin.

Abstract: In a data transfer apparatus such as a Winchester disk drive wherein a transducer or transducers fly over a magnetic disk surface or surfaces during data transfer therewith, a retractor mechanism is provided which coacts with a transducer positioning mechanism for causing the transducer to land on a head landing track disposed radially and inwardly from a series of concentric data storage tracks on the disk, as when the apparatus is electrically turned off. The retractor mechanism includes a spring or like energy storage element in which energy is stored when, with the apparatus powered on, the transducer is first transported by the positioning mechanism from the head landing track to the outermost home track on the disk for initialization.

Abstract: To reliably sheath two coupled conductors of two wires, a tube made of a light transmittable material is fitted to the two coupled conductors and adjoining wire insulating covers; a photohardening resin is put into a gap formed between the tube and the wires; and the photohardening resin is irradiated from outside the tube with an ultraviolet ray into hard polymer. The sheath thus formed is resistant against moisture and strong in mechanical strength.

Abstract: In a magnetic disk apparatus such as a Winchester drive, a head position control mechanism is provided for locking the transducer head on a noneffective surface region of the magnetic disk, where no data is to be stored, as when the apparatus is powered off. A locking lever pivots in a plane parallel to the disk plane for movement into and out of locking engagement with a rotary member rotatable jointly with the head arm about a common axis. A solenoid holds the locking lever out of locking engagement with the rotary member during the progress of data transfer between disk and head. Upon completion of the data transfer, or when the apparatus is electrically turned off, the solenoid becomes deenergized, permitting the locking lever to be sprung into locking engagement with the rotary member. Then the head arm transports the head to, and allows the same to land on, the noneffective surface region of the disk.
