摘要:
A wire-bonding method of an IC uses a capillary having a hole for guiding a bonding wire, the capillary moving vertically and horizontally with respect to the IC so as to bridge a loop between a first bonding and a subsequent second bonding of the wire on predetermined places. The method comprises the steps of heating a wire end extruding from a first opening of the hole to form a ball of the wire; performing the first bonding by a nail head bonding method; pulling the wire coming from the second opening. The tension imposed on the wire hardens a portion of the wire having been softened during the heating process, but is adequately low not break the wire; and moving the capillary so as to perform the second bonding. In a wire-bonding apparatus including a spool and a capillary having a hole to guide the wire therethrough, where the capillary does a first bonding by a nail head bonding method and is movable vertically and horizontally so as to bridge a loop between the first bonding and a subsequent second bonding, there is provided a tension bar, located behind the capillary and rectangular to the wire, to hook the wire at a portion between the capillary and the spool located apart from the center line of the hole. The tension bar is movable from the capillary so as to pull the wire via the hole from the first bonding thus completed. Thus imposed tension hardens the portion of the wire soften by the heat process.

A video signal output device and method are capable of easily displaying moving images while synchronizing transmission-side data and reception-side data even if video data is asynchronously transferred to the reception side from the transmission side. A video signal output device for receiving video data transmitted from a transmitter in sync with a first clock through a communication unit, storing the video data in a storage unit, reading the video data from the storage unit in sync with a second clock, and displaying moving images on a display unit, includes a synchronization adjustment unit for detecting a video data correction amount in accordance with a reference video data amount in one vertical synchronous period and a video data amount of the second clock in one vertical synchronous period to adjust a predetermined horizontal scanning period in accordance with the video data correction amount. The synchronization adjustment unit may distribute the video data correction amount to a plurality of invalid horizontal scanning periods not contributing to the display of moving images and adjust the plurality of invalid horizontal scanning periods.

A sink device including a first data processing unit and a second data processing unit authenticates the processing units, when turned on, to generate first authentication keys having the same data. When a data request is issued from the sink device to the source device, device authentication is made between the source device and the first data processing unit to generate second authentication keys having the same data. The source device encrypts an exchange key using the second authentication key, and sends the encrypted exchange key to the first data processing unit. The first data processing unit decrypts the encrypted exchange key using the second authentication key, encrypts the decrypted exchange key using the first authentication key, and sends the encrypted exchange key to the second data processing unit. The second data processing unit decrypts the encrypted exchange key using the first authentication key to obtain an exchange key.

Provided is an image processing device, including a division area setting unit for dividing and cutting out a plurality of image areas from a single image; and a synthesizing unit for synthesizing into a single image the plurality of image areas divided and cut out with the division area setting unit. By cutting out several arbitrary image areas from the same image output of a single camera and synthesizing and outputting the cutout portion, variations that arise among cameras in a case where several cameras are used will not occur. Further, an image processing unit for performing individual image processing on the plurality of divided and cut out image areas may be further provided, and the synthesizing unit may be used to synthesize the images subjected to individual image processing into a single image.

Lead frame for mounting a semiconductor chip and improving the packing density of devices such as a plastic chip carrier type IC is disclosed. A portion of inner leads, located parallel to the chip stage and the edge of a molded case is made as thin as possible and held by inner lead supporting bars to tie bars until the molding process is finished. After molding process is finished, these bars supporting the leads and stage are cut away. Packing density is improved an amount ranging from 20% to 30%.
