IPC: H04B7/212
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent an interference wave from being relayed while reducing the effect on a system gain and a fade margin. SOLUTION: An interference wave level detection section 12 receives a timing pulse Pi synchronously with an interference wave measuring time slot not used by all stations in a system and detects a level of an incoming IF signal Su2 outputted from a reception section 8 as a level of an interference wave.

Title: Fuse option circuit for memory device
Inventor: KIN TEIHITSU
IPC: G11C17/16
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a malfunction of a fuse option circuit and to improve a yield of production by adding a transistor receiving an output signal from a control signal generator and having a prescribed resistance, to an input end. SOLUTION: When a supply voltage is impressed, a transistor 41 is put in a state of continuity. In the case when a fuse is connected, the potential of a terminal A holds a high level since the equivalent resistance of the transistor 41 is larger than the resistance of the fuse, and an output of an inversion amplifier 14 holds Vcc. The output is unvaried even after a prescribed time passes. In the case when the fuse is cut, on the other hand, the potential of the terminal A holds a low level since the equivalent resistance of the fuse in the cut state is larger than that of the transistor 41, and a transistor 11 is put in a state of continuity. Even when a control signal comes to be in a grounded state after a prescribed time passes, an output B of an inverter holds a high level and, therefore, the output of the inversion amplifier 14 always holds a low level.
