摘要:
An electrical connector comprising a housing provided on one of opposite end portions thereof with an opening through which a flat circuit device is inserted into the housing, a plurality of conductive contacts arranged on the housing for contacting with connecting terminals on the flat circuit device in the housing, and a shell member mounted on the housing and provided therein with a holding portion operative to hold the flat circuit device in the housing. A releasing portion extends from the shell member toward the outside thereof, and a connecting portion extends from the releasing portion in a direction perpendicular to a conductive contact arrangement and the holding portion extends from the connecting portion, so that a folded-back protrusion is constituted in a body in the shell member with the releasing, connecting and holding portions.

An electrical connector including a housing having an opening through which an FPC is inserted into the housing, conductive contacts arranged on the housing for contacting with signal connecting terminals on the FPC, and a conductive shell member mounted on the housing and provided therein with a holding portion for holding the FPC inserted in the housing and a releasing portion for releasing the FPC from holding by the holding portion, wherein the holding portion extends into the housing from an end wall portion of the conductive shell member covering a side end portion of the housing to engage with the FPC and the releasing portion is movable in an operating direction intersecting a direction of arrangement of the conductive contacts and provided thereon with an engaging projection for engaging with the holding portion to release the same from the engagement with the FPC.
摘要:
A digital convergence correcting device effecting convergence correction by using convergence correcting data stored in a memory which includes an address fixing device which, in the case where convergence correcting data are insufficient, reads out in succession the correcting data corresponding to the last horizontal scanning line for the portion lacking in the data so that the correcting data are used repeatedly, and which, in the case where convergence correcting data are excessive, only necessary convergence correcting data are used.
摘要:
A convergence correcting apparatus is used in a projection television receiver including a CRT having an aspherical fluorescent screen and a projection lens apparatus which is attached to the display screen of the CRT and has aspherical plastic lenses. In the digital convergence correcting apparatus, a digital memory stores digital correction data corresponding to correction values of convergence adjustments points indicative of a plurality of points on the display screens divided in the horizontal and vertical directions. A multiplexer reads out predetermined digital correction data from the digital memory and time sharingly multiplexes. At least one digital/analog converter receives the time sharingly multiplexed data from the multiplexer and generates an analog signal. Sample and hold circuits extract a predetermined correction signal from the analog output of the digital/analog converter and sample and hold them. The convergence correcting apparatus is driven in accordance with the respective correction signals held by the sample and hold circuits.
