Title: Data communication system
Inventor: KASUGAI TERUAKI
IPC: H04L12/28
Filed: 1984-03-30
Abstract: PURPOSE:To attain efficient communication by allowing the system to transfer the mode to the polling mode with a signal from a central station, to transmit the information with a signal to the own station, and to restore the system to the contention mode when no polling signal exists for a prescribed time. CONSTITUTION:When power is applied, a host station H and plural slave stations S enter the contention mode so as to allow the stations to conduct data transmission and voice talking optionally. When the H station is transited to the polling mode by manual operation or a timer and outputs a polling signal, all the stations S go to the polling mode, the transmission of information and voice talking are inhibited, and a station S detecting a specific signal of the own station in the polling signal transmits the information. While the station S receives intermittently the polling signal, the polling mode is continued, but if the polling signal is not detected for a prescribed time, the mode is restored automatically to the contention mode, Thus, the communication is attained efficiently.

Title: I2l semiconductor device and its manufacture
Inventor: YAMAMURA KANJI
IPC: H01L27/082
Filed: 1993-03-24
Abstract: PURPOSE:To improve reverse current amplification factor by forming a region the same in conductivity type as a collector region and lower in impurity concentration than the collector region, on the surface part of the inside base region between an outside base region and the collector region. CONSTITUTION:An n-type epitaxial growth layer 3, which has been conventionally a p-type inside base region, is made an n-type region. This is materialized by increasing the accelerating energy of the implantation of ions for formation of an inside base region 6 more than conventionally, and shifting the peak of the distribution of impurity concentration to the side of a p-type silicon substrate 1 thereby reversing the conductivity-type of the surface of the n-type epitaxial growth layer 3. Hereby, since the area of an effective collector increases by the amount of the inside base area being reversed into N, the current amplification factor betau can be improved. Accordingly, it becomes possible to decrease the size of a transistor to about half as large as a conventional one.

     CONSTITUTION: An IF bus extender consists of extenders E1, E2 and a coaxial cable or optical fiber 21, and the E1 and E2 are connected to devices D1WD3 and D4 and D5 via IF sub-buses B1, B2 respectively. The E1 feeds a byte reception instructing signal tnb to the E2 via a transmission path 21 in response to a data effective signal DAV1 of the bus B1 and also feeds a reception not-ready signal NRFD1 and a nonreception signal NDAC1 to the bus B1. The E2 receives the signal tnb and feeds a signal DAV2 to the bus B2. When the E2 receives the signals NRFD2 and NDAC1 from the bus B2, it feeds a byte ready signal rnb to the E1 for data transmission and reception. Thus, the extension of IF buses is made possible to a remote location without requiring special programing.
