Abstract: PURPOSE:To realize the excellent communication performance from the standpoint of the utilizing efficiency of a signal line and a CPU input output port, a data transmission efficiency and a communication speed by applying pulse width modulation to plural data, sending the modulated data serially and allowing a receiver side to send two pulses as a pair periodically. CONSTITUTION:A sender side CPU 1 decides a pulse width of a transmission pulse and sets a leading (ON) time A and a trailing (OFF) time B of a 1st pulse in the decided transmission pulse to a timer match output port P10 and sets a leading (ON) time C and a trailing (OFF) time D of a 2nd pulse to the timer coincidence output port P10. Two 1st and 2nd data are subjected to pulse width modulation and the modulated data are sent serially via a signal line 3. A receiver side CPU 2 executes the reception processing of the signal received from an edge interrupt port P20. In the transmission of the 1st and 2nd data, the 1st data are allocated to a time from the ON timing to the ON timing of the two pulses and the 2nd data are allocated to a time from the OFF timing to the OFF timing of the two pulses.

Title: Sealing method for ceramic package
Inventor: YOKOUCHI KISHIO
IPC: H01L23/02
Filed: 1984-09-12
Abstract: PURPOSE:To accomplish sealing without imposing a thermal impact on a semiconductor element installed on a substrate by a method wherein an electric current is caused to flow through a conductor pattern, composed of two layers of copper and solder, combined with the substrate with the intermediary of a cover for the solder to melt for bonding. CONSTITUTION:A substrate 2 mounted with a semiconductor element 1 and, on the junction with a cover 3 for the sealing of the semiconductor element 1, a metallized layer 4 composed of a copper pattern 6 and a solder layer 5 are provided. When comparison is made between the quantities of resistance presented respectively by the layers 4 and 5, the copper-patterned layer 4 presents a high resistance, substantially, because it is thin. The resistance presented by the layer 5, however, is higher. It follows therefore that most of an electric current runs through the layer 5 when it is applied across electrodes 7, 8 located opposing each other. This sealing method utilizes the Joule's heat in fusing solder that is generated when an electric current flows across the electrodes 7 and 8, with the substrate 2 and the cover 3 kept in contact with each other. Under this sealing method, the device 1 is protected from performance degradation because it may be kept from high temperatures in a packaging process, which is accomplished without employing any large equipment.
