Title: Sealing of semiconductor element
Inventor: MOGAMI KAZUHIKO
IPC: H01L21/56
Filed: 1987-11-18
Abstract: PURPOSE:To simply seal an element without generating the void in sealing resin and raising mounting cost by placing a sealing material in the small plate shape having a through hole on a semiconductor element placed on a substrate and melting the sealing material by heating so as to seal the element. CONSTITUTION:A sealing material 5 is positioned above a semiconductor element 3 fixed by an adhesive layer 2 loaded on a substrate 1 in order to place the sealing material 5 on the element 3 from this state. Normally, the sealing material 5 is placed in the state of being lifted by a wire 4. Then, the sealing material 5 is melted by heating from that state. Being heated, air on the underside of the wire 4 escapes upward through a through hole 5a of the sealing material 5 at the time of heating and melting of the sealing material 5 and subsequently, the sealing material becomes a melting state. Then, in the state, where the sealing material 5 is melted to burry the central part and to swell semicircularly by heating, the element 3 is completely coated and sealed up. Then, being again heated as it is, the sealing material 5 is thermally hardened to finish sealing.

IPC: H04L25/03
Filed: 1989-11-10
Abstract: PURPOSE: To eliminate echo interference and distortion by mapping a 2B1Q symbol to a symbol which a new symbolic alphabet corresponds to and performing convolution between the new symbol and plural gain coefficients and adding plural amplified outputs to give the convolution result. CONSTITUTION: A received 2B1Q signal Q is shifted left by one bit to generate a corresponding shifted symbolic alphabet S. Next, this shifted signal is supplied to a delay line provided with taps at intervals of a length corresponding to the symbolic width of the reception signal. Each tap along the delay line is connected to a summing device, which supplies an output y(n), through an amplifier. Tap gains, namely, coefficients aj are so set that interference effects from symbols adjacent to a desired symbol with respect to time should be subtracted. The output y(n) is obtained by convolution between a transmitted symbol s(n) and gain coefficients aj . Further an error factor is subtracted from this convolution result to give a compensation result which compensates mapping of the 2B1Q symbol to the new symbolic alphabet.
