Title: Ring trip circuit
IPC: H04M19/02
Filed: 1992-03-19
Abstract: PURPOSE:To offset an AC component at the time of comparing DC levels by a comparator and to omit a low-pass filter by superimposing the same AC component as the AC component, which is superimposed to signals on a subscriber line to be compared, to the signals to be compared. CONSTITUTION:A comparator 23 receives signals just proportional to signals appearing on a subscriber line 12 at a first comparative input. On the other hand, the comparator 23 receives signals applying a signal processing to the output of a potential divider circuit 33 at the second comparative input. A bypass filter 31 passes only the AC component of a ringer signal Sr. An adder 32 superimposes the DC level from a DC power source 22 corresponding to a threshold voltage Vth to the output of the bypass filter 31. The output of the adder 32 is impressed to the second comparative input of the comparator 23. Thus, the low-pass filter for removing the AC component can be unnecessitated.

Abstract: PURPOSE:To display the number of copying sheets in a way so as to prevent the mis-operation by an operator, by controlling the point of the time when the display for the number of copying sheets is to be changed according to a copying state. CONSTITUTION:The number of copying sheets set on the 1st display means 5 with an input means 3 is transferred to the 2nd dispaly 6 upon starting of copying so as to be displayed thereon. The displayed number is subtracted upon lapse of each prescribed time after the start of copying. When the displayed number attains 1, whether the next original is inserted or not at the similar point of subtraction time is investigated and if the original is inserted, the dispalyed number is subtracted and if no original is inserted, the display number is not subtracted immediately, and after the final paper is discharged, the display number is subtracted to 0. Therefore, the number of copying sheets is displayed in such a way as to prevent such operator's mis-operation by which the electric power source is turned off while the copying paper remains in a copying state in the copying machine.

Abstract: PURPOSE: To minimize the contact area of a gate door with sea water by a method wherein the skin plates of upper and lower stages are both disposed facing the sea, at a two staged roller gate of a river-mouth weir where water flows from river to the sea.  
     CONSTITUTION: A lower stage door a whose cross section is trapezoidal-shape is fixedly installed on a river bed. A skin plate 4 contacting with sea water at the lower stage door a is extended vertically high upward, a reinforcing girder 5 being provided therewith, while a buffer belt for packing purpose is mounted at the sliding part at the tip of the girder 5. An upper stage door b having the same cross section with the lower door is disposed at an upper position of the lower stage door a in the manner that the skin plate 10 of the upper stage door b moves vertically slidingly with the packing buffer belt of the lower stage door a. By disposing the skin plates 10, 4 of the upper stage door b and the lower stage door a respectively facing the sea B, the contact areas of the two doors with sea water are minimized, lessening the adhesion of maritime organisms and the generation of rusts to be caused by sea water, resulting in the elongation of the durability of the doors.
