Title: Method for catching control signal
Inventor: SHINGU KAZUMI
IPC: H04W36/08
Filed: 1988-03-31
Abstract: PURPOSE:To efficiently catch a control signal by catching the control signal without changing a receiving channel for a constant time and deciding whether the control signal is out of a utilizing range or the temporary degradation of a wave condition. CONSTITUTION:When a power source is applied, CPU 1 detects the receiving channel of the control signal in the first unit of an IDROM 3 according to the program of an ROM 2 and the frequency of the detected receiving channel is set through a synthesizer part 5. Next, the presence and absence of a carrier is detected by a detector 6 to decide whether the frequency to be same as this frequency is set from a control station or not. Then, when the carrier is detected, the synchronous detection of the control signal is executed and a catching condition is decided. At such a time, when the catching condition is satisfied, since it can be considered that the control signal is positioned in the utilizing range of the control station, the control signal is caught and a timer circuit 4 is set. Then, operation is moved to waiting operation such as call processing and reception processing, etc. After that, a time over is investigated and when the time is not over, the recovery of transmission quality is waited. Thus, even in the case of a momentary trouble, the synchronous detection can be executed as soon as the recovery is obtained.

Abstract: PURPOSE: To make possible maintenance of the revolution of a motor during winding by mechanical means of less numbers by forcefully maintaining the close state of a motor driving switch by the switch actuating member responding to the driving at the winding of a winding system driving member.  
     CONSTITUTION: As a motor revolves, a main gear 10 is rotated by way of reduction gears, causing a winding drive plate 28 to turn. At the same time, the cam face 27 of the drive plate 28 engages to the actuator 36 of a switch actuating member 33 and pushes the same rightward. As a result, the bent part 38 at the end pulls a switch actuating piece 40 to close the corresponding switch 39. At the same time, the engaging part 45 of the engaging member 46 engages to the protrusion 44 of the switch actuating member 33 and therefore the moving state is maintained. Upon completion of winding, the second protrusion 42 of the cam plate 42 kicks the roller 49 of the stopping member 46 and therefore the engagement to the engaging member 45 and protrusion 44 is released and the cam face 27 of the winding drive plate 28 also disengages from the actuator 36, hence the switch actuating member 33 is reset leftward by the spring characteristic of the switch actuating piece 40, by which the switch 2 is opened to stop the motor.

Title: Lighting system for fluorescent lamp of facsimile reader
Inventor: SAWADA MITSUSHI
IPC: H04N1/04
Filed: 1983-05-07
Abstract: PURPOSE:To prolong the life of a fluorescent lamp by preheating a fluorescent lamp for a constant irreducible necessary time based upon the filament characteristics of the fluorescent lamp when reading operation is started, and stopping the preheating when the fluorescent lamp turns on. CONSTITUTION:When an automatic original feeder is in use, original sensors S1-S3 operate once an original is set at a specific position, and the original is conveyed in the direction of a readout line by turning on a start button in said state. When the original is inserted manually, the original is conveyed when original sensors S1-S3 are turned on. The power source 12 for a lighting device turns on synchronously with said original conveyance to start the preheating of the fluorescent lamp 7. Consequently, a fluorescent lamp lighting signal becomes active a specific time after the fluorescent lamp 7 is preheated to turn on the fluorescent lamp 7, so said preheating is cut off after the fluorescent lamp turns on. Thus, the cumulative preheating time determining the life of the fluorescent lamp is shortened to prolong the life.

Filed: 1982-05-14
Abstract: PURPOSE:To add a defect detecting circuit and a display lamp, which facilitate the defect detection, to every printed circuit board in the static device consisting of plural printed circuit boards. CONSTITUTION:When the input at a point (a) of a logical circuit board 20A is L, an output point a' is L if the circuit is normal, but it is H if the circuit is defective. Consequently, if the circuit is defective, the output of an EXOR circuit 22A becomes H, and the output of an OR circuit 23A becomes H, and a display lamp 24A is extinguished, and thus, the logical circuit board 20A is judged to be defective. When all of inputs (d)-(f) are L in a logical circuit board 21A, an output point d' is L also; but if the point d' is H because of the defect of an OR circuit or a TIMER circuit, the output of an EXOR circuit 22D becomes H, and a display lamp 24B is extinguished. Thus, a circuit which compares logical levels of input and output points is added to every logical circuit board and the state of the logical circuit board is indicated on the lamp to discriminate easily defective boards.
