Patent JP-H0396057-A (JP)
Title: Polarity inversion detection circuit
Inventor: OISHI YOSHIKATSU
IPC: H04M11/00
Filed: 1989-09-07
Abstract: PURPOSE:To distinguish no-ringing service from general telephone service by identifying a time required for polarity inversion. CONSTITUTION:The voltage Va of a diode bridge circuit 3 drops transiently in the general telephone service, and rises again, however, since only the operating time of a converter is required for reaction time, no sufficient discharge of a capacitor 16 occurs, and the output of a comparator 8 keeps an 'H' level. When the no-ringing service is utilized, the polarity of a telephone circuit is changed moderately, and since the sufficiently low time constant of the capacitor 16 and a resistor 17 can be obtained, the voltage of the capacitor 16 follows the output voltage Va of the diode bridge circuit 3. Since sufficiently high time constant of a capacitor 12 and resisters 13, 14 can be obtained in discharge, a voltage Vd goes to a constant voltage, and a voltage Ve becomes less than the voltage Vd, and the output level of the comparator 8 is changed, thereby, a response is obtained only in the no-ringing service.

Abstract: PURPOSE:To relax a stress, which is generated in a semiconductor element due to the flexibility of a sealing resin, and to prevent a semiconductor device from being broken by an external force by a method wherein a sealing resin having a low Young's modulus is used as the above sealing resin. CONSTITUTION:A semiconductor element 2 is sealed in a module substrate 3 with a sealing resin 1 and thereafter, the substrate 3 is bonded to a vinyl chloride card 4 to constitute an IC card. At this time, a resin having a Young's modulus of 200kgf/mm<2>, such as an acrylic photo-setting resin, is used as the sealing resin 1. Thereby, a stress, which is generated in the semiconductor element, is reduced and a possibility of the breaking of a semiconductor device is reduced.
