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.

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.

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.

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.

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.

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.
