Title: Phase control circuit
Inventor: YAMAMOTO HIROSHI
IPC: G05F1/56
Filed: 1983-08-23
Abstract: PURPOSE:To obtain an inexpensive and small-size phase control circuit having a small circuit loss by measuring the load resistance value at a place near the zero point of a full-wave rectified power supply to convert the resistance value into voltage and controlling the load current via a linear phase control circuit based on said converted voltage. CONSTITUTION:The AC power supply voltage undergoes full-wave rectification, and a DC, which is charged up to the maximum level of the power supply voltage, is obtained by a capacitor 6. A zero point detecting circuit 7 is driven so that switches 8 and 10 are closed at a place near the zero point of the full-wave rectified voltage. As a result, a fixed level of current is supplied to a load current 4 through a constant current circuit 9 to produce a voltage drop. At the same time, a capacitor 11 is charged up to the terminal voltage of the resistance 4. These actions end when the switches 8 and 10 are opened. In this case, the charging current of the capacitor 11 is proportional to the load resistance. Therefore the average load current which is delivered with control from a linear phase control circuit 12 is kept constant despite a change of the resistance 4.

Title: Sheet sorter
Inventor: ANZAI TOSHIKI
IPC: B65H39/11
Filed: 1987-06-19
Abstract: PURPOSE: To prevent sheet bundles from being mixed with each other when they are taken out in a batch from bins, by providing sheet shifting means for pressing and shifting the sides of sheets discharged onto the bins, in all bins so that the sheet shifting means in each adjacent bins are directed reverse to each other.  
     CONSTITUTION: In such a case that sheet bundles 24a through 24e discharged onto bins 9a through 9e are shifted for every stage, when a shift button 10 is depressed to turn on a switch 12, a motor 13 rotates rotary shafts 14, 17 in directions reverse to each other so that side end regulating plates 18a, 18c, 18e at every other stage are moved rightward by a pinion and rack mechanism while the remaining side end regulating plates 18b, 18d are moved leftward. With this arrangement, the sheet bundles 24a through 24e are pushed in their respective directions, and when the other side ends thereof abut against stationary side end regulating plates 19a through 19e, the motor 13 is stopped. Thereafter, the motor 13 is reversed to return the side end regulating plates 18a through 18s, so that the sheet bundles 24a through 24e are staggered in a removable condition. Thus, even though the sheet bundles are taken out in a batch, it is possible to prevent the sheet bundles from being mixed with each other.

IPC: H04L69/40
Filed: 1994-07-06
Abstract: PURPOSE:To switch a communication line from an analog private line into an analog public line even on the occurrence of a fault in a transmission line for a backup setting modem. CONSTITUTION:When a fault takes place i a transmission line (line 132) of a backup setting modem 11, the fault is detected by a line fault detection section 121 of a non-backup setting modem 12. The detected output is fed to a carrier control section 124 via a selector switch 125. Thus, the carrier transmission operation of the carrier transmission section 121 is stopped. As a result, a reception carrier of the modem 11 is interrupted. Thus, the line fault detection section 112 of the modem 11 discriminates the occurrence of the fault in the reception line (line 131). As a result, a backup start section 113 executes the processing of switching the communication line from an analog private line 13 into an analog public line 14.

Title: Phase synchronous circuit
Inventor: SHIMA TAKESHI
IPC: H03L7/085
Filed: 1978-12-15
Abstract: PURPOSE:To avoid the backlash by putting the phase comparator featuring a small transition number in parallel to the conventional frequency comparator. CONSTITUTION:In parallel to double input frequency comparator 4, 1/2 dividers 6 and 7 are installed to the input step of double input phase comparator 8. The lock range is magnified double and equivalently at the input step of the divider. The output of two comparators are piled on to each other at the charge pump step or the loop filter step. Thus no discontinuity is caused to the phase comparison range by the parallel distribution of the dividers. As a result, the gain never lowers down for the phase comparator even near the steady point, thus avoiding the backlash without causing any delay to the phase comparison.
