Title: Power mos transistor with overcurrent preventing function
Inventor: NAKAGO MANABU
IPC: H03K17/08
Filed: 1990-02-15
Abstract: PURPOSE:To prevent an overcurrent by a method wherein a voltage between a drain and a source generated by a current flowing through a first vertical type MOSFET is detected by a second vertical type MOSFET and second and third resistors and a gate voltage of the first vertical type MOSFET is controlled. CONSTITUTION:When a positive voltage is impressed on a gate terminal G, a first vertical type MOSFET Q1 which is main power MOSFET is put in an ON-state and successively a second vertical type MOSFET Q2, which is a vertical MOSFET, is put in an ON-state. This lag in the time is determined by a resistor R1. By a current flowing through the first vertical type MOSFET Q1, a voltage is generated between a drain and a source. The voltage is detected in split resistors R2 and R3 of the second vertical type MOSFET Q2, and when a voltage of a prescribed level or above is generated, a third vertical type MOSFET Q3 turns ON and operates to lower a gate voltage of the first vertical type MOSFET Q1 and to hold back the current to a prescribed value. Thereby an overcurrent is prevented.

Title: Microwave detection circuit
Inventor: YOKOYAMA HIROAKI
IPC: H03D1/10
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To vary the detection sensitivity of a post stage microwave detector without affecting a microwave level propagated in a transmission line by cascade-connecting the microwave detectors for plural stages and impressing the detection voltage of preceding stage microwave detector detection to the post stage microwave detector as a DC bias voltage. SOLUTION: Propagation microwaves are branched into the microwaves of a coupling degree corresponding level in directional couplers 11 and 12 and impressed to the diodes D1 and D2 of the preceding stage and post stage microwave detectors. After detecting them, the diode D1 takes out a positive side DC component through a filter part constituted of capacitors C11 and C12 , a resistor R12 and an inductance L and impresses it to the diode D2 as the DC bias voltage. Thus, the entire signals are shifted to a + side for the DC component. Thus, a level at the time of performing half wave rectification in the diode D2 becomes larger compared to the time without impressing the DC component, and when it is smoothed in the capacitor C21 , a large detection voltage can be obtained.
