IPC: F02B37/12
Filed: 1983-09-22
Abstract: PURPOSE:To prevent the high-temperature exhaust gas of a working group of cylinders from entering into a resting group of cylinders and thermally deteriorating their fuel injection valves in an engine in which the resting group of cylinders are put off of operation depending on the running condition of the engine to operate the working group of cylinders. CONSTITUTION:In the operation of all cylinders of an engine, an intake shutoff valve 35 in a second intake passage 7 is opened, an exhaust recycling valve 36 in an exhaust recycling pipe 9 is closed, and the driver 51 for a waste gate valve 48 in a second turbocharger 42 is connected to an intake pipe 5. In the slow and rapid operation of the engine, a shutoff valve 31 in a communication passage 8 is opened. In the medium-speed operation of the engine, the shutoff valve 31 is closed. The intake efficiency of the engine is thus heightened. When the output power of the engine has dropped below a prescribed level, the intake shutoff valve 35 is closed and the exhaust recycling valve 36 is opened so that no intake is supplied from the intake cylinder 5 to a second group B of cylinders. At that time, the driver 51 for the valve 48 is connected to the atmosphere to move a diaphragm 53 leftward by a spring 54 to forcibly close the valve.

IPC: G02F1/35
Filed: 1989-07-07
Abstract: PURPOSE:To prevent the shutdown of the entire system even in the event of the shutdown of an exciting system by forming at least one of optical fibers or optical waveguides of a medium which is transparent to light of the use wavelength and forming at least the other one piece of an amplifying medium for the light of the use wavelength. CONSTITUTION:At least one of the optical fibers 12, 13 of the optical coupler 11 which is disposed with plural pieces of the optical fibers 12, 13 or the optical waveguides in proximity to each other to generate distributed coupling are formed of the medium which is transparent to the light of the use wavelength. At least the other one of the optical fibers 12, 13 or the optical waveguide are formed of the medium which amplifies the light of the use wavelength. As a result, the amplifying effect of the amplifying medium can be utilized and, therefore, the larger branching ratio of the optical coupler 11 is obtd. and the installation of many optical signal receivers is possible. The distributed coupling to the transparent medium is annihilated and light information (q) is outputted and transmitted from a transparent medium side in case in which the optical amplifier changes to an optical absorber when the excitating source to the amplifying medium is shut down by a certain cause. The shutdown of the entire system is prevented in this way even if the exciting source shuts down.
