Abstract:
A document feeder of an image forming apparatus includes a guide that arranges a width of a recording medium. A recording medium pickup module picks up the recording medium. A recording medium pickup module shifting unit shifts the recording medium pickup module in association with the movement of the guide. The recording medium pickup module includes a guide rack connected to the guide at one end. A pinion unit supports reciprocating motion of the guide rack. A pickup rack engaged with the pinion unit linearly reciprocates in parallel with the guide rack, and is connected to the recording medium pickup module.

Abstract:
The present invention relates to a cobalt (Co) and platinum (Pt)-based multilayer thin film having a novel structure and perpendicular magnetic anisotropy, and to a fabrication method thereof. More specifically, the invention relates to a cobalt and platinum-based multilayer thin film having perpendicular magnetic anisotropy (PMA), which includes thin cobalt layers and thin platinum layers alternately deposited over a substrate, and has an inverted structure in which a thickness of the thin cobalt layers is greater than that of the thin platinum layers, and to a fabrication method thereof. The cobalt and platinum-based multilayer thin film has a new structure in which the thickness of a magnetic thin layer is greater than that of a non-magnetic thin layer. The multilayer thin film may be easily applied as a free layer and a pinned layer in a magnetic tunnel junction by controlling the perpendicular magnetic anisotropy energy depending on the thickness ratio of the layers. Also, the multilayer thin film has excellent thermal stability, and thus maintains its PMA energy density even after being subjected to a heat treatment process. In addition, it enables a fine amount of in-plane magnetic anisotropy to be formed by heat treatment so as to reduce the critical current density required for magnetization switching. Therefore, it may be advantageously used for high-performance and high-density MRAM.

An adhesion layer may bond the second semiconductor chip to the first semiconductor chip and may bond the second semiconductor chip to the support plate. In addition, an electrical coupling may be provided between the first semiconductor chip and the packaging substrate.

Abstract:
Provided are a tape feeder for use in chip mounters that can reduce a chip feeding duration and prevent chips from being turned over or assuming wrong postures to feed the chips stably, and a chip mounting method. The tape feeder includes a second link having one end linked to a link shaft through which a first link and a pivot lever are combined and the other end in which a slot curved at a predetermined inclination is formed. The velocity at which a carrier tape is fed changes according to the inclination of the curve of the slot with respect to the moving direction of the first link, the curve contacting the contact unit upon the movement of the first link in a direction helping to rotate a ratchet gear.
Abstract:
A mobile terminal and control method to share content with a device and control the device are provide. The mobile terminal includes a communication unit to communicate with a host and the device; a search unit to receive content information and device information; an input unit to receive a content selection signal and a device selection signal; and a control unit to control the mobile terminal. The mobile terminal receives content information from a host and selects content to be outputted to a device selected from device information from the host. The mobile terminal controls the selected device using control commands transmitted to the selected device based on a control mode. If the control mode is not stored in the mobile terminal, the mobile terminal may receive the control mode from the host.
