Title: Power supply voltage monitoring circuit
Inventor: MIURA KIWA
IPC: H02M1/00
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To monitor the feeding condition of AC voltage in real time by outputting an alarm signal, if the voltage value which is detected by a voltage detection means is a prescribed value or lower. SOLUTION: This power supply voltage monitoring circuit is formed such that a voltage detection circuit 40 is connected to the previous stage of a rectification circuit 20, to detect the voltage value of AC voltage before rectification is conducted at the rectifying circuit 20. If the supply of the AC voltage to an AC input terminal 10 is stopped due to the generation of a trouble, power supply output voltage is continuously outputted from an power supply output terminal 30 for a while thereafter, by electric charges which are stored in a smoothing capacitor 23 in the power supply voltage monitoring circuit. If the supply of the AC voltage to the AC input terminal 10 is stopped, the apply of the AC voltage to diodes 41, 42 is stopped immediately after that.  Therefore, a voltage value detected at a voltage detection part 44 becomes a prescribed value or lower, and an alarm signal is outputted from an AC interrupt alarm 45. As a result of this, it is possible to monitor the feeding condition of the AC voltage in real time.

Abstract: PROBLEM TO BE SOLVED: To easily and surely attach and detach a core pipe by providing a core pipe pushing device formed of a moving mechanism fixed to an arm and moved in the axial direction of a web roll, a pressing plate fixed to the tip of the moving mechanism, and a guide mechanism for regulating the moving direction of the pressing plate in the axial direction of the web roll. SOLUTION: When a core pipe 3 is removed, the rod of a cylinder 31 is pushed out from the state where it is contracted in no contact with a chuck. At this time, a blade 34 touches the rear end surface 14 of a guide 12 to push the core pipe 3 in the axial direction. Since a claw 26 is radially minimized along a taper part 2 7 according to this movement, the claw 26 and the inner surface of the core pipe 3 which are strongly pressed to each other are separated to eliminate the constraining force to the core pipe 3, and the core pipe 3 is thus separated from the chuck. This operation is performed from both sides of the core pipe 3, whereby the core pipe 3 is perfectly released from the chuck and fallen. Since the core pipe 3 is not directly pressed, but the end surface of the core pipe 3 is pressed along the axis in a wide circumferential range, the core pipe 3 is never damaged.
