When a voltage is applied between element electrodes 2 and 3, a strong electric field is generated in the vicinity of a crack formed between deposits composed manly of carbon. When the intensity of the elastic field reaches a fixed valued or more, a tunnel current is carried from the vicinity of the crack of the first deposit toward the vicinity of the crack of the second deposit, and the electron which has tunneled partially scattered in the vicinity of the crack of the second deposit. To provide an electron emitting efficiency of a certain fixed value or more, the elastic scattering probability to the electron on the deposit is important. An image forming device of high brightness and high quality with low power consumption can be realized.

Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To avoid the influence of a reflected wave signal to the other signal line when a bus line on a mother board becomes non-termination. SOLUTION: When a package is connected to the bus line 10, a flip flop FF 5 is made to a set state. A relay contact point 7 is on/off-controlled in accordance with the output level of FF 5. FF 5 is set in response to the drop of a voltage level at the time of connecting the package. FF 5 is reset by a reset signal or a power on reset signal inputted from outside. Consequently, an electric connection state between the bus line and a signal power source can be controlled in accordance with the presence or absence of the connection of the package on the bus line 10 and influence by the reflected wave signal can be avoided when the bus line 10 becomes non-termination.
