Title: Optical fiber amplifier
Inventor: OKAMURA KOJI
IPC: H04B10/29
Filed: 1990-01-19
Abstract: PURPOSE:To decrease the coupling loss to a fiber for a transmission path by fusing the side face of a 2nd optical fiber having the mode field diameter approximately equal to the mode field diameter of the fiber for the transmission path near to the end part on the down stream side in the propagating direction of the signal light and stimulating light of a rare earth-doped fiber and stretching the fused part. CONSTITUTION:The side face of the 1st optical fiber 2 where the signal light propagates is fused near to the end part on the incident side of the stimulating light of the rare earth-doped fiber 1 and the fused part is stretched to constitute the ampli fier in such a manner that the signal light and the stimulating light propagate in the rare earth-doped fiber 1. The side face of the 2nd optical fiber 3 having the mode field diameter approximately equal to the mode field diameter of the fiber for the transmission path is fused near to the end part on the down stream side in the propa gating direction of the signal and stimulating light of the rare earth-doped fiber 1 and the fused part is stretched to constitute the amplifier in such a manner that only the signal light amplified in the rare earth-doped fiber 1 is coupled to the 2nd optical fiber 3. The increase in the coupling loss by a difference in the mode field diameter is prevented in this way.

Title: Color temperature correction circuit
Inventor: OTSUKA MASATAKA
IPC: H04N9/73
Filed: 1993-01-21
Abstract: PURPOSE:To correct the color temperature of a white color portion without losing the color reproduction of a colored portion. CONSTITUTION:Levels of three color difference signals in a white color portion having no color are all zero, the output voltage of a maximum value circuit 7 is equal to the reference voltage of a voltage source 8 and a comparator 9 switches on a switch 3. Thus, a current I (=K.Y) generated from a voltage control current source 2 is added to a current of a color difference signal B-Y to increase a level of the color difference signal B-Y. Thus, the white color is corrected in a direction of a blue color, that is, in a higher color temperature direction. Furthermore, since at least one level of three color difference signals is higher than zero in a colored portion, a maximum value of the color difference signals is higher than the zero level without fail and the comparator 9 turns off the switch 3. Thus, the color difference signal B-Y is not corrected. Thus, the color temperature is not corrected in the colored portion and no fluctuation in a DC voltage is caused between the input and the output of the color difference signal.

Filed: 1987-01-16
Abstract: PURPOSE:To extend feasible distance of remote control by relay transmitting a remote control signal, which is received from a transmitter in optional direction, at the proper level of the remote control signal. CONSTITUTION:In a first period of a signal pulse train, a signal light 1a from the transmitter 1 is photoelectrically converted by a light receiving element 8, passed through amplifiers 15 and 16 and stored in a storage circuit 26 through a switch 27a.

Filed: 1993-01-22
Abstract: PURPOSE:To allow the calibration of the aging of an environment sensor by storing the output voltage for a predetermined time or predetermined times in an output level memory means, operating the average value thereof, making a decision whether the average value comes within a reference level range, and switching the output resistance based on the decision results. CONSTITUTION:Only a switch SW3 is turned ON to connect a resistor R3, as an output resistor, in series with a sensor S. Output level of the resistor R3 is stored in a RAM2 every several seconds and then written, as a current output level, into a RAM1 and the oldest data in the RAM1 is discarded. The output level stored in the RAM2 is compared with an operating level in a ROM and when the output level is higher, an alarm is produced notifying that the object to be detected is higher than a predetermined amount. When the output level is lower, monitoring operation is repeated. At a predetermined check time, average value of output level in the RAM1 is determined and a decision is made whether the average value comes within the reference level range of the ROM. When the average level deviates from the reference level range, a decision is made that the sensor S is aged and an MPU controls each switch to switch the output resistance thus correcting the aging.

Abstract: PURPOSE:To improve combustion, by providing an intake diverting recess on the outer part of the inside of an intake port provided with a curved passage, to cause an intense swirl in a combustion chamber. CONSTITUTION:When an engine is working under low and medium load, an intake mixture introduced into an intake port 16 flows straightly in a rectilinear passage 18 as shown by an arrow 17 and reaches a curved passage 20 so that  the mixture curves while gathering to the outer part of the curved inside of the passage 20 and would directly flow toward a spark plug 10 in a combustion chamber 8 along the inside circumferential surface of a cylinder 2. However, since a recess 26 is provided on the outer part 24 of the inside of the curved passage 20, the mixture is diverted by the recess 26 as shown by an arrow 27, so that the mixture curves and then flows into the combustion chamber 8 in the tangential direction 29 of the cylinder 2, thereby causing an intense swirl in the combustion chamber. When the engine is working under high load, a larger quantity of intake mixture flows into the intake port 16 but the inflow of the mixture into the combustion chamber 8 is not hindered by the recess 26, so that the efficiency of charging into the combustion chamber is kept high.
