Title: Surge protective circuit
Inventor: MIZOGUCHI SATOSHI
IPC: H02H3/22
Filed: 1991-11-12
Abstract: PURPOSE:To protect inner circuit against breakdown by providing a PN junction element having reverse bias withstanding voltage lower than that for a circuit to be protected, and an amplifying element connected to form a current path between power supply terminals on highest and lowest potential sides and receiving a breakdown current, flowing through the PN junction element, as an amplification control current. CONSTITUTION:When a positive surge voltage to be applied between power supply terminals 1, 3 exceeds the collector-base withstand voltage of a transistor Q1, a breakdown current flows from the collector to the base of the transistor Q1. The breakdown current serves as the base current of a transistor Q2 to conduct the transistor Q2 and thereby a current, equal to the base current multiplied by a current amplification factor, flows between the collector and emitter of the transistor Q2. Consequently, a surge current can quickly be fed from the power supply terminal 1 toward the power supply terminal 3 by means of the transistor Q2. According to the invention, inner circuit 4 can be protected against breakdown even upon application of a positive surge between the power supply terminals 1, 3.

Filed: 1988-11-24
Abstract: PURPOSE:To shorten a time from the generation of a change to the preparation of correcting cost information by executing the partition and division of an exchange in a network for the unit of the several exchanges, setting a presentative exchange and a slave exchange in one section and after that, executing the repetition and transfer of data from an originating terminal equipment to a destination terminal equipment while data exchange in section and data exchange between sections are repeatedly executed. CONSTITUTION:For the respective exchanges in the non-hierarchical communication network, the every several exchanges in a comparatively short distance are defined as one section and the respective exchanges are divided into the plural sections. Section representative exchanges 20A-20N are respectively set in each section and plural in-section slave exchanges 21A-21N are set excepting for the representative exchanges. In order to determine a route to a destination terminal equipment 1n, the in-section slave exchange 21A inquires to the section representative exchange 20A. The section representative exchange 20A retrieves the route, for which the minimum communication cost is enough, to a section 200n. Then, at such a time, a retrieved route (c) is informed of the in-section slave exchange 21A. Thus, the time from the correction of cost information to the restart of the communication can be shortened.

Title: Method and device for accessing dram
Inventor: TAKAGI SHIGERU
IPC: G11C11/409
Filed: 1989-11-17
Abstract: PURPOSE:To secure a holding time with respect to a column address considerably long and to access low speed DRAM whose precharge time is long at high speed by using address signals corresponding to respective banks of DRAM. CONSTITUTION:A DRAM controller 5 transmits the address signals MAD0 and MAD1 to the banks #0 and #1 of DRAM 3 with strobe signals RAS0, CAS0 or RAS1 and CAS1. When signals MAD0, RAS0, CAS0 or the signals MAD1, RAS1 and CAS 1 are respectively inputted to the banks #0 and #1, CPU 1 reads and writes data through a data bus 4 in correspondence with read/write signals at that time. With such constitution, the address signals MAD0 and MAD1 corresponding to respective banks #0 and #1 of DRAM3 are generated and accessed. Thus, the holding time with respect to the column address can be secured considerably long and the data processing of high reliability can be executed even if access time is furthermore shortened as CPU is speeded up.
