Title: Optical receiver, wavelength multiple optical receiver, time division multiple optical receiver and optical transmission system using them
Inventor: KENJO SATOSHI
IPC: H04B10/564
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To improve a signal light-to-noise ratio by providing a light source that generates offset light, an optical coupler which combines signal light and the offset light and a saturable absorption type optical element which inputs an optical coupler output and outputs it to a receiving circuit. SOLUTION: Signal light 11 transmitted from a transmission line 4 is transmitted to a receiving circuit 2 via a saturable absorption type optical element 3 which suppresses the light noise of the light 11. The element 3 has a saturable absorption effect due to the reverse bias voltage application to a semiconductor waveguide and has a nonlinear transmitted characteristic depending on input light intensity. Although a data pulse having large light intensity exceeds the absorption capability of the optical element and is transmitted, a noise component having small light intensity receives strong absorption and is reduced. Because of this, a pulse waveform of a peak value which includes the noise component and exceeds the threshold levels of the transmitted characteristic and the absorption characteristic can be made to a pulse waveform that reduces the noise component.

IPC: B41J29/42
Filed: 1993-03-26
Abstract: PURPOSE:To miniaturize an ink jet printing apparatus by setting the ink emitting area due to a printing head so as to make the same larger than the distance between both ends of a printing medium to continuously enable the printing of a good image. CONSTITUTION:When ink is emitted to a printing medium 236 using a printing head 209, the ink emitting area due to the printing head 209 is set so as to become larger than the distance between both ends of the printing medium 236. When printing is applied to the printing medium 236, the printing head 209 is driven to emit ink to the area set by an area setting means corresponding to an image signal. By this constitution, ink emitting operation is performed before printing is practically applied to the printing medium and the same effect as empty emission is generated.

Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To discharge clean exhaust gas during ignition by a method wherein a heat exchanger is heated by the heat generated by an electric heater when the heating demand is small, and combustion takes place after the electric heater is energized to heat the heat exchanger when the heating demand is large. SOLUTION: Power is supplied to an electric heater 7 to heat up a burner port 5 and the inside of a combustion chamber 4. Power supply to the electric heater 7 is stopped after the inside of the combustion chamber 4 reaches a specified temperature, and a fuel feeder, a fan and an igniter 6 are brought in operation. A mixed gas sent from a mixing part 3 burns at the burner port 5. When air is heated up to a specified heating temperature, the hot air is sent into a room. When the temperature inside the room rises and the heating load drops, the temperature of hot-water rises. A temperature detector 15 detects that to stop the combustion. Power is supplied to the electric heater 7 and a fan 2 is operated in a weak mode. When the heating load drops and the temperature of hot water rises further, the amount of power supply to the electric heater 7 is reduced.  When the heating load increases, fuel supply starts.

Abstract: PURPOSE:To shorten a waiting time up to the reclosing of a power source by connecting a level shifting Zener diode through a diode directly with an AC power source and commutating a thyristor conducted at the abnormal time therewith. CONSTITUTION:The resetter of a protecting circuit rectifies an AC power source 7 via diodes 16 and level-shifts it via a Zener diode 17. An electrolytic condenser 19 is charged by the current flowed through the diode 17, the voltage is divided by resistors 20, 21, and applied to a transistor (Tr)22. When a malfunction occurs in a control circuit 2 in this state to cause a thyristor 3 to be conducted, an electrolytic condenser 23 is discharged, and when an AC switch 5 is opened OFF due to the recovery, the condenser 23 is discharged to turn OFF the Tr22. Thus, when the switch 5 is reclosed, the Tr22 is immediately turned ON to cause the thyristor 3 to be reversely biased. Accordingly, the thyristor 3 is turned OFF to start the control circuit 2.
