Patent JP-S5818134-A (JP)
Title: Pressure converter
Inventor: UCHIYAMA KAORU
IPC: F02P7/077
Filed: 1981-07-24
Abstract: PURPOSE:To perform pressure conversion suitable for engine control, by providing a dead band circuit between amplification stages of the output of a semiconductor strain gauge. CONSTITUTION:When a pressure P is applied to a semiconductor strain gauge G, a piezoelectric resistance G2 is increased and a G1 is decreased. Thus, the voltage at the middle point of a bridge of the gauge G is changed, and an output (v) of a differential amplifier A1 is linearly changed with the pressure P. The relation between this output (v) and an output E0 of an amplifier A2 to a connecting point e1 of resistors R1 and R2 and a connecting point e2 of resistors R3 and R4 is e2<e+VF and e1>e-VF where the forward voltage drop of diodes D1 and D2 is VF forward voltage and the diodes D1 and D2 are turned off. Thus,  the e1 and e2 become a prescribed value (e) independently and a dead band is  produced. Thus, an output E0 has a dead band and the dead band level can be  obtained by suitably setting the resistors R1-R4.

Title: Digital type electronic tuning system
Inventor: IKEGUCHI SHIGEHIKO
IPC: H03J7/02
Filed: 1984-06-04
Abstract: PURPOSE:To attain the reception in the range of correct tuning even if there is a variation in a ceramic filter at the preset channel selection using a PLL loop by employing a voltage synthesizer system for the PLL synthesizer system. CONSTITUTION:When a PLL loop is locked by the PLL operation, an output signal is generated from a lock detecting circuit 23, and when a broadcast signal exists in this state, an SD signal is generated from an IF level detecting circuit 24. Then a signal throwing a switch 22 to the position S is outputted from a control circuit 21 and the operation is changed over from the PLL operation to the AFC operation. Thus, an S curve signal of a detecting circuit 6 is amplified by a DC amplifier 12 and applied to a charge pump 13. An output signal of the pump 13 is converted into a DC voltage by a low pass filter 11 and applied to a local oscillating circuit 10 and a varactor of a radio frequency amplifier circuit 3, then the receiver is brought into the correct tuning state.
