Abstract: A transmission system includes: a transmitter configured to transmit a first signal; a receiver configured to receiver a second signal from the transmitter; and a bias circuit configured to regulate a direct current bias level of an input terminal of the receiver, wherein the transmitter includes a first amplitude converter configured to convert the first signal to the second signal having a smaller amplitude than an amplitude of the first signal, wherein the receiver includes a second amplitude converter configured to convert the second signal to a third signal having a larger amplitude than the amplitude of the second signal, and wherein the first amplitude converter includes a first capacitance that restricts an amount of charge to be supplied to the receiver.

Abstract: Disclosed is a fuel gas supply adjuster which allows free adjustment of the flame length and enables stable flame length adjustment, for example in a gas lighter. In the fuel gas supply adjuster of the invention, a membrane filter which can provide a minimum necessary fuel retaining volume is used as the filter so as to prevent the fuel from being fed excessively at the initial ignition. Moreover, in order to incorporate the membrane filter in a fully sealed structure with a minimum necessary space being secured therein, one surface of the membrane filter is brought into close contact with that surface of an elastic member which has a conical recess, and the other surface thereof with the pressing face of a pressing member, while the other face of the elastic member with the fitting face of a base member, and the side face thereof with the side sealing face of the base member, respectively.
