Title: Asynchronous time division multiplex transmission equipment provided with switch element
IPC: H04L12/54
Filed: 1991-04-01
Abstract: PURPOSE: To require only a slight storage capacity of an intersection buffer and to prevent the occurrence of blocking of transmission by transmitting a cell between the intersection buffer and an output buffer at an intermediate transmission speed higher than an element transmission speed. CONSTITUTION: The speed at which a cell is supplied to a cell filter 7 and is read into an intersection buffer 15 corresponds to a prescribed element transmission speed. That is, the transmission speed of the cell is dependent upon a prescribed clock frequency till the cell reaches the intersection buffer 15. However, the cell is transmitted from the intersection buffer 15 to an output buffer 17 through a connection line 16 at a higher intermediate transmission speed. The speed is increased by raising the clock frequency. Individual bits of the cell are transmitted at least partially in parallel, that is, a prescribed number of bits of the cell are simultaneously sent through the connection line 16, thus realizing implementation more easily.

IPC: H01L21/338
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a negative resistance type diode having new structure in which a tunnel current amount can be varied by altering the thickness of a third semiconductor. CONSTITUTION:A thin third semiconductor 17 having electron affinity smaller than those of first and second semiconductors 15, 16 is inserted between the first semiconductor 15 and the second semiconductor 16 for forming a second type of hetero junction. Accordingly, when a predetermined voltage is applied to the semiconductors 15, 16, if a bias is small, two-dimensional electrons are tunnel-passed through the semiconductor 17, introduced to a vacant level of two-dimensional hole, and a tunneling current flows. Then, if the bias is increased, vacant level is eliminated, and a tunneling current from electrons does not flow. If the bias is further sufficiently increased, a vacant level is newly generated, and a tunneling current again flows. Thus, negative resistance type voltage/current characteristic is obtained. A tunnel diode of new structure is obtained.
