Title: Multi-system sound intermediate frequency processing unit
Inventor: OKUNO KAZUHIKO
IPC: H04N5/46
Filed: 1992-09-17
Abstract: PURPOSE:To facilitate the circuit integration by reducing the number of externally mounted components such as a changeover switch in the multi-system sound intermediate frequency processing unit so as to simplify the processing unit. CONSTITUTION:A selection means SE1 selects an FM signal having carrier frequencies of 5.5-6.5MHz from an inputted sound intercarrier signal and converts the carrier frequencies into 6MHz by using a 0.5MHz reference signal. A selection means SE2 selectively transmits an FM signal whose carrier frequency is 4.5MHz. A doubler 9c doubles a carrier frequency of 4.5MHz. A frequency conversion means CO1 converts a carrier frequency of the FM signal outputted from the doubler 9c into 6MHz. Then the carrier frequency of the FM signal is unified to be 6MHz and the frequency shift is kept the same simultaneously and the FM detector 15a detects the FM signal. Thus, the FM detector 15a copes with the almost equal frequency shift and the same carrier frequency and the circuit such as a changeover switch or the like is omitted.

Title: Ic card
Inventor: NONAKA YASUHIRO
IPC: G11C5/14
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the power consumption of a battery when a power supply is cut off in a card connection state by using a diode to prevent a current path reaching a signal input terminal from the battery via a resistance. CONSTITUTION:The output of a decoding IC 2 assures a high potential by means of a gate control signal (p) which is delayed after the make of a power supply at insertion of a card. Meanwhile an input terminal AIN has a high potential owing to the make of the power supply and has a level equal to the potential difference level of a RAM 3. When a card is pulled out, the connecting nodal point N between a resistance R and a capacitor C is separated from a power supply terminal 1 and a battery 4 via the diodes D1 and D2. Therefore, the electric stored in the capacitor C is discharged with the time constants of the C and the R without causing such an inconvenient case where the electric charge of the C is discharged to the outside or the C is charged by the battery 4. The terminal AIN is kept at a high potential for a certain period of time by the current secured at the discharging time. Then the RAM 3 is inactivated by the output of the IC 2 and the signal (p) before the high potential level of the terminal AIN drops.
