Title: Terminal controller for wire telephone line
Inventor: ITOU KOUICHI
IPC: H04M11/06
Filed: 1983-04-28
Abstract: PURPOSE:To secure prevention against an erroneous incoming call by inhibiting incoming call connecting operation based upon the detection output of a call signal detecting circuit when some terminal in a station originates. CONSTITUTION:When a call signal from a switchboard arrives at terminals L1 and L2, the call signal detecting circuit 23 detects it and outputs an H signal to an output line (a), and terminals A and B generate ringing tones. When the terminal A in the station originates, signals (l) and (l') are connected with low impedance in terms of DC and relay contacts K1 and K1', and K3 and K3' are turned on and as a result made to terminate the terminals L1 and L2 by a terminal A with low impedance. This is detected by the switchboard, which transmits a dial tone. Then, dial pulses of the terminal A are sent to the switchboard, and an OR gate 30 outputs only a low-level signal even if the call signal detecting circuit 23 detects it erroneously to output an H signal to the signal line (a), so that neither of relay contacts K2 and K2' turn on. Therefore, erroneous incoming to a terminal B due to the calling of the terminal A is prevented.

Abstract: PURPOSE:To detect the presence of a source substance with the presence of conduction between electric conductors by providing two lead wires in a depth direction on the inner wall of a crucible in which the source substance dissolved and evaporated by heating is filled. CONSTITUTION:The opening part of a molecular beam cell 1 penetrates into a liquid nitrogen shroud 5 arranged to the inside of a growth chamber 8 and appears in the space of the inside of the growth chamber and is directed to the base plate holding face of a manipulator holding a semiconductor base plate. Tantalum wires 3 are provided along the inner wall of a crucible 2. The liquid face of source substance is vaporized from the opposed positions of its mouth edge. The tantalum wires are lengthened to the lower limit in the direction of the bottom of the crucible in which the intensity of finally necessary molecular beams is generated. For example, when the conduction between the tantalum wires is eliminated by vaporization of Ga, a detector 4 connected to the tantalum wires 3 loses the conduction performed until this time, detects and announces it. Therefore the detector 4 is equipped with a power source. When source substance is vaporized and the liquid face is lowered from the lower ends of the tantalum wires, the conduction is interrupted. Thereby the detector having a form for alarming the interruption of the conductor may by utilized. Replenishment or replacement of the source substance is performed by this alarm.
