Title: Method and device for removing of element
Inventor: KOBAYASHI KATSUO
IPC: H05K3/34
Filed: 1980-01-28
Abstract: PURPOSE:To enable the element to quickly be removed by a method wherein the element deposited on a printed substrate is pulled upward leaving held, and a fixed part is fused to be separated from the substrate. CONSTITUTION:Elasticity of a spring 36 is controlled by moving a screw 32 up and down according to a size of the element, and a rod 26 is elastically moved down to cause pawls 46, 48 to be engaged with the both ends of the element 52. When the pawls hold the element with the help of a spring 50 and release a thrusting force against the rod 26, the element 52 is given a climbing power by the spring 36. When a solder 58 fixing legs 56 of the element is heat-fused from the reverse side of a print plate 54, the fixing is released to cause the legs 56 to be separated from the substrate 54. A stopper 34 is contacted with a laterally built-up member 12 after the separation. With this construction, the element can quickly be removed.

Abstract: PURPOSE:To detect a hook state of a branch telephone set properly under various conditions independently of an installation condition of the facsimile equipment by detecting the hook state of the telephone set connecting to a line based on a digital signal from an A/D converter means. CONSTITUTION:A voltage detection circuit 3 detects a voltage of a line L and provides an output of an analog signal corresponding to the voltage to an A/D converter 4, which samples the analog signal by a prescribed period to convert the signal into a digital signal and the resulting signal is given to a signal processing section 1 as voltage data. When a branch telephone set D is hooked off, a voltage of the line 1 changes by nearly 10V, a mean value of the voltage data is rapidly decreased and the signal processing section 1 discriminates the hook-off state of the branch telephone set D based on the voltage change. Even under a bad installation condition, for example, even when a distance from a telephone station is remote and the voltage of the line L is lower than 48V, since the signal processing section 1 discriminates the hook-off state based on the voltage change, the signal processing section 1 discriminates accurately the hook-off state of the branch telephone set D.
