CONSTITUTION:A dial number input circuit 5 fetches a dialed dial number and when talking lines 9 are all busy, it is detected by a control signal transmission reception circuit 2 and reported to a control circuit 4. Then a dial number is stored in a storage circuit 6 under the control of the control circuit 4 and when an idle line is caused in the lines 9, it is detected by the control signal transmission reception circuit 2 and reported to the control circuit 4. Then the control circuit 4 gives a command of line connection to the idle line to a line selection circuit 1, reads the dial number from the storage circuit 6 and it is fed to a dial signal transmission circuit 3 to send a dial signal to a private branch of exchange (PBX). When dialing is given, as soon as an idle line is caused, the idle line is connected automatically.

IPC: G01L9/04
Filed: 1989-10-27
Abstract: PURPOSE:To detect pressure with high sensitivity by using a MOS transistor (TR) as a pressure-sensitive element and detecting the pressure as the change of the gate potential. CONSTITUTION:A gate electrode 2 is made of a conductive material above a diaphragm 1, and a source electrode 3 and a drain electrode 4 are formed by diffusing phosphorus, etc., on a P-type silicon substrate 5. A MOS TR 21 is an equivalent circuit of the pressure sensor. A gate electrode 22 corresponds to the electrode 2, and a source electrode 23 and a drain electrode 24 correspond to electrodes 3 and 4. The gate voltage and source and drain voltages are applied from a gate voltage power source 25 and a source voltage power source 25 so that the TR 21 is operated in the saturation area. The drain current at this time is measured by an ammeter 27. The voltage to be measured is introduced from the side of a diaphragm substrate 8. The distance between the gate electrode 2 and the substrate 5 is shortened by the voltage to be measured. The change of the distance corresponds to the change of the gate voltage. The change of the gate voltage is measured as the change of the drain current by the ammeter 27. Thus, the change of the pressure is substituted with the change of the gate voltage of the TR 21 and is measured as the change of the drain current.
