Filed: 1984-01-26
Abstract: PURPOSE:To make it possible to enhance measuring acuracy without sacrificing the strength of a pressure-sensitive structure, by bringing the vertical side surfaces of a pair of sense-of-pressure sensors to a close state and arranging strain gauge adhering surfaces so as to direct both of them outwardly. CONSTITUTION:One vertical side surfaces of a pair of sense-of-pressure sensors 21A, 21B are mutually brought to a close state and vertical side surfaces having strain gauges 6 adhered thereto are arranged so as to be mutually directed outwardly while a separate one set of the same pair is arranged so as to be spaced apart by an interval 8A from the former pair. By this arrangement, wirings, which are connected to output terminals 6A, on a substrate 7 are brought to a mutually opposed state. As compared with such a case that sensors 21A, 21B are arranged in a state separated so as to hold the interval 8A therebetween, strength possessed by a pair is reinforced by 50% and the measuring accuracy thereof is enhanced by about 50%. Therefore, the arrangement density of the sense-of-pressure sensors arranged in an array form is enhanced without sacrificing the strength of the pressure-sensitive structure formed of single crystal silicon and measuring accuracy can be enhanced.

Title: Tuner
Inventor: SAKAMOTO SHUJI
IPC: H04B1/26
Filed: 1986-01-22
Abstract: PURPOSE:To possibly reduce the deterioration of noise figure NF at UHF reception by using at least one of amplifier elements of a VHF turner circuit at the reception of an UHF signal as an intermediate frequency amplifier to reduce the power voltage of the intermediate frequency amplifier at the reception of the UHF signal. CONSTITUTION:Since a voltage is applied to an UHF power terminal +UB at the reception of an UHF signal, a switching diode D2 is energized and a power supply voltage is applied to a transistor (TR) Q1. As the power supply voltage supplied to the TR Q1 acting like an intermediate frequency IF amplifier, a voltage dropped by a resistor R8 is applied. Further, the gain of the TR Q1 is decreased by increasing the resistor R8 connected in series with the UHF power supply terminal +UB. In such a case, since the power supply voltage applied to the TR Q1 acting like the IF amplifier is reduced, the gain is suppressed without deteriorating the noise figure.
