Patent JP-H05183470-A (JP)
Title: Signal transmission circuit
Inventor: SUKEGAWA SHUNICHI
IPC: G11C7/06
Filed: 1991-11-22
Abstract: PURPOSE:To enable the high-speed signal transmission with low power consumption by prolonging the signal transmission distance while amplifying signals through the positive feedback of an intermediate amplifier circuit having terminals sharing I/O to be transmitted to a receiver circuit. CONSTITUTION:When an intermediate amplifier circuit 1 is at the driving state, the voltage of contact points IO1 and IO2 are divided into 'H' and 'L' levels from the VDD/2. The effective threshold value between the cross connected transistor Tr and MOST 17, pMOST 19, nMOST 18, and pMOST 20 makes one Tr threshold voltage. As a result, the contact point IO1 becomes 'H' and the IO2 'L'. The contact point N2 is turned from 'H' to 'L' level, and the N4 is turned from 'L' to 'H' level. Therefore, pMOST 5 and nMOST 8 are turned on to drive the contact point 101 which is becoming at the 'H' level further in 'H' level and to drive the contact point IO2 which is becoming at the 'L' level further in the 'H' level, resulting in applying positive feedback to both contact points. Thus, the signal is amplified because of the positive feedback of the circuit 1, enabling transmitting signals at a high speed and with low power consumption.

Abstract: PURPOSE:To give a comfortable feeling in driving to driver by remarking inter- vehicle distance information which occupies a large role in forward visible information received by the driver in running, and imparting an appropriate stimulus to the inter-vehicle distance information. CONSTITUTION:A means 61 in an ordinary operation and a means 62 in auto- speed control ASC selection are provided as throttle control means. When distance between a preceding vehicle goes into a prescribed range in the ASC selection, fixed speed control by a speed target control part 63 is switched over to fixed inter-vehicle distance control by an inter-vehicle distance control part 64, and fluctuation based on 1/f fluctuation is imparted to target intervehicle distance as the control amount by a fluctuation imparting means 31. Fluctuation width or fluctuation speed can be varied corresponding to the speed, and also, a lower limit value of the inter-vehicle distance is set corresponding to the speed, and the impartment of fluctuation can be limited so as to prevent the target inter-vehicle distance from being reduced to be lower than the lower limit value.

IPC: H03D9/06
Filed: 1991-12-18
Abstract: PURPOSE:To unnecessitate the feeder line of a local oscillation signal by spatially supplying local oscillation power with light modulated by the local oscillation signal. CONSTITUTION:A high frequency signal inputted to a high frequency signal input terminal 5 is inputted through a microstrip line, which is composed of a strip conductor 3 and a ground conductor, to a filter 30.

The modulated energy supply power is inputted to the light emitting element. The element 6 generates light modulated by this energy supply power. The semiconductor element 20 is irradiated with the amplitude modulated light generated from the element 6. In the semiconductor element 20, an intermediate frequency (IF) signal is generated by mixing the high frequency signal and the local oscillation signal. The generated IF signal is passed through a filter 31 and outputted from an output terminal 4. Thus, even when the interval of the mixer is narrow, the local oscillation signal can be supplied to the mixer.
