摘要： An image pickup apparatus includes a zoom lens having a first positive lens unit, and a first negative lens unit disposed on an object side of the first positive lens unit. A distance between the first positive lens unit and the first negative lens unit is narrowed at the time of zooming from a wide angle end to a telephoto end. The zoom lens includes an aperture stop disposed between a lens nearest to an image side in the first negative lens unit and a lens nearest to the image side in the first positive lens unit, and a light-amount reducing filter made of a resin material which is disposed on the image side of the lens nearest to the image side in the first positive lens unit, and which can be inserted in an optical path and withdrawn from the optical path. The zoom lens satisfies predetermined conditional expressions.

摘要： A sheet metal-made cup-shaped material including a circular base plate portion and a cylindrical portion extends from an outer peripheral edge portion of the base plate portion in one direction along the axis of the base plate portion. An annular groove is formed in an upper end portion of the cylindrical portion, whereby an annular projection that projects in a direction opposite to a direction along which the cylindrical portion extends is formed in the cylindrical portion. The annular projection and the cylindrical portion are clampingly pressed to a degree at which the annular groove at least disappears, whereby the outer circumferential face of the projection and the outer circumferential face of the cylindrical portion are flush with each other. Therefore, the axial length of a sheet metal-made back face pulley is increased, and the whole of the increased axial length can be used as the effective length.

摘要： A lens unit consists of a plurality of lens frames, a stepping motor, and a driving control unit. The plurality of lens frames for holding an imaging optical system lies in a lens barrel and moves over a stowage interval and a zoom interval. The stowage interval is an interval between a position of stowage at which the lens frames are stowed and a ready-to-image position at which imaging is enabled. The zoom interval is an interval over which the ready-to-image position exists and a power varying action is executed. The stepping motor moves the plurality of lens frames. During execution of a thrusting action or storing action, the driving control unit drives and controls the stepping motor in a first driving mode. The thrusting action is executed for moving the plurality of lens frames from the position of stowage to the ready-to-image position. The stowing action is executed for moving the lens frames from any position within the zoom interval to the position of stowage. During execution of a zooming action for moving the lens frames over the zoom interval, the driving control means unit drives and controls the stepping motor in a second driving mode in which a lower current is used than in the first driving mode.

摘要： An integrated lead suspension includes a solder ball that is placed between a lead wiring pad provided on a flexure of the suspension, and a bonding pad provided on a slider of a head gimbal section. The lead wiring pad and bonding pad are soldered by melting the solder ball. As a result, there is provided a recessed section into which a solder ball is placed by way of surface raised sections, using gravitational force, in the vicinity of the center line of the surface of the lead wiring pad. In this way the position of the solder ball is not displaced from the center line when a bonding pad and lead wiring pad are connected by means of a solder ball.

摘要： A slider and suspension of a hard disk drive are joined with a low modulus epoxy adhesive. The slider and suspension are set in a bonding jig while they are moving from process to process or subjected to a thermosetting treatment in a controlled temperature chamber. The slider and suspension must be kept bound together with the bonding jig until the adhesive is cured through a thermal treatment. The low modulus epoxy adhesive is cured with heat from a laser beam. In addition, a resistance value of the head disposed at the slider is measured so as to monitor the temperature of the head, thereby deciding both output and irradiation time of the laser beam for obtaining a desired strength of the bond within a predetermined temperature range.
