Abstract: A sheet conveying device includes a conveyor, a sound collector, and circuitry. The conveyor conveys a sheet. The conveyor conveys a sheet in a sheet conveyance direction. The sound collector collects an operating sound generated by a conveyance of the sheet. The circuitry is to extract a feature amount of the operating sound collected by the sound collector, and determine, at different positions in the sheet conveyance direction based on the feature amount, whether an abnormal conveyance of the sheet occurs until the sheet is conveyed to a given position in the sheet conveyance direction.

Abstract: A sheet processing apparatus that forms a folding line on a sheet includes first and second folding rollers that form a folding line on the sheet by rotating a bent sheet while pinching from sheet surfaces and a first pressing unit that presses the second folding roller against the first folding roller in an arbitrary portion in a rotating shaft direction of the second folding roller.

Abstract: A knocking sensor including: a sensor body including, a metal shell including a tubular portion and a flange portion, a piezoelectric element, a weight sandwiching the piezoelectric element with the flange portion, a flange portion-side electrode plate placed between the piezoelectric element and the flange portion, a weight-side electrode plate placed between the piezoelectric element and the weight, a flange portion-side insulating plate placed between the flange portion and the flange portion-side electrode plate, and a weight-side insulating plate placed between the weight and the weight-side electrode plate; and a resin molded body made of a resin and covering the sensor body, wherein the resin molded body is made of polyphenylene sulfide, and wherein the flange portion-side insulating plate and the weight-side insulating plate are made of a resin that does not contain ester bond.

Abstract: A conveying unit receives a sheet from an upstream unit and conveys the sheet on a conveying path. A stacking unit stacks the sheet conveyed from the conveying unit. An aligning unit sets the sheet back in a direction opposite to a sheet conveying direction and aligns the sheet by bumping the sheet against a reference wall. A sheet discharging unit discharges the sheet aligned on the stacking unit. When a predetermined condition is satisfied, a control unit sets a timing for discharging the sheet by the sheet discharging unit earlier than a normal sheet discharge timing.

Abstract: A knock sensor 1 for attachment to an internal combustion engine. The knock sensor 1 includes a cap 41a and a support member 11. At least a part of the top surface of the support member 11 is covered by cap 41a to prevent a mounting bolt 91 from directly making contact with the top surface of the support member 11 when the mounting bolt 91 extends through a through-hole 71 in the sensor. The cap 41a covers the top surface of the support member 11 to protect the support member from being ground or abraded by the mounting bolt 91.

Abstract: A disk drive includes a substantially rectangular box-shaped casing having a rectangular mounting surface. In the casing are arranged a disk drive mechanism. A rectangular control circuit board is mounted on the mounting surface of the casing. The control circuit board has four sides aligned with the four sides of the mounting surface, and four corners have recesses to expose the four corners of the mounting surface to permit handling of the disk drive without damaging the control circuit board.

Abstract: A disk assembly, which includes a large number of magnetic disks arranged in layers on a disk loading hub, is detachably mounted on a rotating shaft of an air spindle motor that is set on a base. The base has thereon a movable table capable of reciprocation. The movable table carries thereon a rotary positioner for rotating and positioning a stacked head assembly, which is formed of a large number of magnetic heads stacked in layers, and a plurality of ramps for loading into and unloading the magnetic heads from the magnetic disks. The distance between the respective rotating shafts of the air spindle motor and the rotary positioner can be adjusted by moving the movable table.

Abstract: Thread grooves (internal threads) for electrical connection are directly formed in two mounting portions among a total of eight mounting portions provided in the side surfaces and bottom surface of the base plate of a magnetic disk device which are provided in two positions electrically far from the magnetic head with respect to the noise frequency. The two mounting portions are grounded to the chassis of a system having the magnetic disk device mounted thereon. Mounting members having the electrical insulating property are fitted in the mounting holes of the six mounting portions which are disposed in positions electrically closer to the magnetic head and the mounting members are electrically isolated from the chassis of the system when they are mounted on the chassis of the system by use of fixing screws.

Abstract: A magnetic disk drive comprises a motor having a substantially cylindrical rotor, and three magnetic disks each having a center hole in which the rotor is inserted, and fitted on the outer circumferential surface of the rotor. The magnetic disks are displaced in a direction along the diameter of the rotor so that the inner circumferential edge of each magnetic disk defining the center hole is pressed against the outer circumferential surface of the rotor. The magnetic disks are fixed to the rotor by a fixing member mounted on the rotor. A counterweight for correcting the balance of the magnetic disk in rotation is mounted on the fixing member in the vicinity of that region of the outer circumferential surface of the rotor against which the inner circumferential edges of the magnetic disks are pressed.

Also, an assembling method and assembling unit suitable for installing the head assembly to the head arm in the case that a plurality of head arms are installed integrally onto the arm supporting block. Because a plurality of head arms are installed integrally onto the arm supporting block, its assembling work is simple, the cost is decreased, and still more it is possible to effectively reduce a latent off-track of magnetic head.

Abstract: A carriage mechanism for a magnetic disc includes a head arm rotatable around a rotational center. A slider is supported by the head arm and arranged such that its principal axis forms a specified angle with a straight line passing through the rotational center of the head arm and a center of the slider, so as to reduce the yaw angle of the slider. A magnetic head having a magnetic gap is provided in the slider. The principal axis of the gap passes through the center of, and extends in the lengthwise direction of the gap. The magnetic head is so arranged that an extension of the principal axis of the magnetic gap passes through the rotational center of the head arm and forms a specified angle with the principal axis of the slider, in order to reduce the azimuth angle of the gap.
