A communication system includes a power-sourceless terminal (10) and a transmitting station (20). The power-sourceless terminal includes a photoelectric conversion section for receiving an intensity modulated optical signal and converting it to an electric signal, and a voice output section for outputting the electric signal passing through the conversion by the photoelectric conversion section in the form of voice. The transmitting station includes a transmission section for transmitting the optical signal having its intensity modulated depending on an electric signal of the information to be transmitted.

The invention provides a new authentication system which is capable of not being deceived by copied images and excellent in authentication accuracy and convenience. An image with built-in authentication information to be used for authentication is emitted by an emission angle-dependent light emitting device while being diffracted at a specified angle. An emission angle-dependent light for detector 22 collects a diffracted light, and a control device 23 converts it into an image in the form of an electrical signal. The image in the form of an electrical signal is used for authenticating.
摘要:
A system for blow-by gas return to the combustion chamber of an engine according to the present invention including an oil separator with an inlet communicating with an outlet through a diffusion chamber and a filter element; said oil separator communicating with the crankcase of the engine through a breather and an inlet pipe, and also communicates with the intake manifold of the engine through an outlet pipe, so as to separate the oil from the blow-by gas almost completely. The oil separator and the inlet and outlet pipes are disposed in a space directly over the cylinder head of the engine and the intake manifold, so as to prevent ice accumulation therein by the radiation and convection of engine heat thereon. The diffusion chamber of said oil separator is also in communication with the atmosphere by an atmospheric passage so as to prevent the flow of oil into the combustion chamber when unusually large quantities of blow-by gas are produced and the back pressure in the intake manifold becomes unusually low.
