摘要:
In a magnetic disk apparatus using a composite thin-film magnetic head, high-speed reading and writing operations are achieved without increasing a read error rate and without decreasing a signal-to-noise ratio of read signals. The magnetic head is moved along an arc-like line on the magnetic disk having a track including a plurality of sectors. Each of the sectors has a data area and an identification area displaced from the data area due to movement of the magnetic head relative to the magnetic disk. A position identification sector which is positioned ahead of a target sector is determined based on a predetermined factor representing a period of time. An offset operation of the magnetic head is performed after the position identification sector is detected by a read head so that the magnetic head is moved from a first position to a second position. The read head tracks on the identification area when the head is at the first position and the read head tracks on the data area when the head is at the second position. The predetermined factor is measured since the identification sector was detected. A data reading operation is performed when a measured value of the predetermined factor reaches a predetermined value.

The pillar garnish is supported by a steel bracket interposed between the pillar garnish and the pillar. The bracket includes a body frame having a substantially channel-like cross section formed by a top surface opposite to the pillar garnish, and two side surfaces extending from two edge lines of the top surface substantially perpendicular to the top surface toward the pillar, the body frame having free ends of the two side surfaces which are welded to the pillar, a claw portion projecting over the body frame and capable of being connected to the pillar garnish, and a plurality of tag portions formed between the side surfaces of the body frame, the tag portion extends from a cut portion formed in the top surface of the body frame in the same direction as the direction of the free end of either side surface of the body frame, and a free end of the tag portion is positioned at a position defined by a distance shorter than the distance from a free end of another side surface of the body frame to the top surface of the body frame, the free end of the tag portion being formed to substantially run parallel to the top surface toward outside.

A controller for a cutting machine has a machining power extracting unit for extracting machining power related to machining from the consumed power of the cutting machine, a detection range setter for setting a detection range for the machining power thus extracted, an integrator for integrating output values of the machining power extracting unit within the detection range thus set, a maximum value detector for detecting the maximum value of the output values of the machining power extracting unit within the detection range, and a judging unit for comparing an input signal with a variable comparative reference value and producing a control signal if the input signal exceeds the comparative reference value. The judging unit has an input which is selectively connectable to the machining power extracting unit, the integrator and the maximum value detector.
摘要:
A carrier for a developer comprising a core material coated with a coating material consisting essentially of a copolymer of vinylidene fluoride and trifluoroethylene or hexafluoropropylene is disclosed. The carrier causes neither fog generation in the initial stage of running nor contamination of a developing machine because of its high rate of charge increase and satisfactory resistance to surface contamination, and exhibits excellent adhesion between the core material and the coating material.

The present invention provides a composite color image forming method. The method includes electrically charging a latent image-holding member; exposing the charged latent image-holding member to light to form an electrostatic latent image; developing the electrostatic latent image with a two-component developer containing toner particles of one color and a carrier to form a toner image on the latent image-holding member; primarily transferring the toner image from the latent image-holding member to an intermediate transfer member; repeating the electrically charging, the exposing, the developing, and the primarily transferring, while the toner particles are replaced with toner particles of different color, to form a composite color image on the intermediate transfer member; and secondarily transferring the composite color image from the intermediate transfer member to a recording medium. The carrier contains magnetic substance-dispersed core particles in which a magnetic substance is dispersed in a resin, and a coating layer that coats the surface of each of the magnetic substance-dispersed core particles at a covering rate of 95% or more. In addition, the carrier has a degree of circularity of 0.970 or more. The intermediate transfer member is a belt that has a substrate whose Young's modulus is in the range of 3,000 to 6,500 MPa. During the primary transferring, primary transfer nip pressure is in the range of 8 to 20 gf/cm, and a value (T/P) obtained by dividing a primary transfer current value T (μA) by a processing speed P (mm/sec) is from 0.08 to 0.18.
