Title: Method and die for resin molding electronic device
Inventor: OSADA MICHIO
IPC: B29L31/34
Filed: 1995-04-14
Abstract: PURPOSE: To eliminate resin flash efficiently at the time of resin molding a flexible printed circuit board having significant variation in the thickness. CONSTITUTION: The depth A of a recess 4 for setting a printed circuit board 3 is set slightly shallower than the minimum thickness (t) of the printed circuit board. The circumferential part 11 on the bottom of the printed circuit board 3 is stopped at a stop part 4a provided on the bottom of the recess 4 and the bottom part of the printed circuit board 3 is supported by a resilient supporting member 9 except the stopped part. Under that state, the circumferential part 11 on the bottom of the printed circuit board 3 stopped at the stop part 4a on the bottom in the recess is pressed strongly with a predetermined mold clamping pressure by means of upper and lower dies 1, 2 thus forming a resiliently compressed part 12.  With such arrangement, a gap is eliminated between the circumferential part 11 on the bottom of the printed circuit board 3 and the stop part 4a in the recess and between the upper peripheral edge of the printed circuit board and the surfaces of both dies 1, 2.

Abstract: PURPOSE:To increase not only the image resolution in the vertical direction but the S/N, by transferring the signal charge accumulated by the photoelectric converting element via the vertical transfer means comprising the resistive gate electrode type transfer element and then reading the signal charge via the horizontal transfer means. CONSTITUTION:The signal charge converted by the P-N junction photodiode 501 is read out in a fixed period and with every line and via the gate element 502 which is turned on and off by the scanning pulse supplied from the vertical scanning circuit 508. The charge read out is transferred to the row direction 521 via the transfer part comprising the new-type resistive gate electrode type charge transfer element 507 having several transfer electrodes and the circulating scanning circuit 513. The signal charge transferred to the direction 521 is then transferred to the line direction 531 via the horizontal transfer part 525 comprising the charge transfer element to be read out through the output terminal 530. With use of the element 507, the vertical image resolution can be increased. And no mixture of the spike noise of the scanning pulse is caused owing to the use of the transfer part 525 to increase the S/N.
