Title: Inclination sensor
Inventor: TOMIKAWA INEO
IPC: G01C9/12
Filed: 1984-01-23
Abstract: PURPOSE:To obtain an inclination sensor free of variation in responsiveness by forming a pendulum member of a nonmagnetic material with good conductivity, and damping the pendulum member electromagnetically with a permanent magnet provided on a substrate. CONSTITUTION:The pendulum member 1 varies in angle to the substrate according to the inclination angle of an automobile. At this time, the pendulum member 1 rotates crossing the magnetic flux of the permanent magnet 3. When the pendulum member 1 rotates at a speed (v) as shown by an arrow, a voltage is induced at the pendulum member 1 perpendicularly to the rotational direction and an eddy current is generated by the induced voltage as shown by an arrow. Force proportional to the speed (v) is generated by the eddy current in the opposite direction of the rotation of the pendulum member 1 and serves as damping force to stabilize the rotation of the pendulum member 1. Therefore, a detection signal obtained at a photoelectric converting element 4 is a stable electrical signal from which variation components due to oscillation of the automobile and pulsation of the pendulum member 1 are removed.

Title: Amplifier circuit
Inventor: FUKUSHIMA HIROYUKI
IPC: H04B7/26
Filed: 1985-01-26
Abstract: PURPOSE:To obtain an economical amplifier circuit operated stably by decreasing the attenuation of an attenuator when a power voltage is fed to an amplifier and increasing the attenuation when the power is cut off. CONSTITUTION:Attenuators 15 and 16 consist of PIN diodes or the like and the attenuation is minimized at application of power and maximized at interruption of power. When amplifiers 2 and 3 are operated, e.g., a power switch 5 is disconnected from the connecting state to inactivate an amplifier section 6, causing the input/output VSWR to be deteriorated. Even when the isolation between ports of a distributor 1 and a synthesizer 4 resultingly is decreased, the maximum attenuation of the attenuator 15 is increased more than the amplification gain of the amplifier 3 and the back isolation quantity as the amplifier 2 is selected to a sufficiently large value. Since no positive feedback loop is formed with respect to the amplifier 3, even when the power of one system is disconnected, a gain reduction of nearly 6dB exists, but the operation is continued stably.
