Title: Power feeding method for digital extension telephone
Inventor: OSANAWA TATSUHIRO
IPC: H04M1/72
Filed: 1986-02-18
Abstract: PURPOSE:To allow at least one of telephone sets connected to a controller to be used in case of a power failure by supplying DC electric power to an optional telephone set in use from a station when there is the telephone set in use at the time of the power failure of an AC power source, or supplying the DC electric power from the station to only a telephone set connected to a specific extension terminal when there is no telephone set in use. CONSTITUTION:At the moment when the AC power source enters the power failure state, a power failure detecting circuit 13 detects the power failure by monitoring the output voltage of a power feeding circuit 12 and informs a control circuit 11 of that fact. The control circuit 11 switches a changeover switch 10 to the side of a by-pass line 4 and also switches either of changeover switches 8 and 9 to the side of the by-pass line 4 according to the use states of telephone sets A and B. In this case, a trunk line terminal 3 is connected to the side of an electric power separating circuit 7 when a control current is supplied to a relay and to the side of the by-pass line 4 when the control current is ceased. Consequently, no control current needs to be supplied during the power failure, so a normal electromagnetic relay which is not a self-holding type, etc., are usable as the changeover switch 10.

Title: Elbow for transferring pulverulent body with air current
Inventor: OODE TADAYUKI
IPC: F16L57/00
Filed: 1984-02-23
Abstract: PURPOSE:To diffuse pulverulent body transferred with air current to prevent a bend from local wear by forming a piping connecting end of an elbow into a cylindrical shape and the section of the bend into a square or the like. CONSTITUTION:The section of a piping connecting end 4 of an elbow is formed into a cylindrical shape, and a bend 5 has the section formed into a square or the like. Thus, air current flowing into the bend 5 becomes expanded turbulence when the section is transferred from the cylindrical shape to the square shape or the like. Pulverulent body 6 transferred with the air current while being diffused is deposited biased on the outer peripheral inside surface of the bend 5 by an inertia force. Thus, the outer bottom surface of the bend 5 wears uniformly without being cut off locally like in the case of a round pipe.
