Title: Ring data communication network
Inventor: DENISU FUITSUSHIYAA
IPC: H04L12/437
Filed: 1989-04-10
Abstract: PURPOSE: To make it unnecessary to add any media access controller by mutually connecting a main data path and a second data path in one terminal so that a control rotating ring can be turned into a single ring in which data are advanced on the both data paths. CONSTITUTION: This figure shows that a terminal 21 generates a fault, and a terminal should be removed from a network. It is judged that inside connection in a terminal 20 is changed so that a media access controller MAC 14 of this terminal can co-operate only with an encoder/decoder 12. Data are advanced to the encoder/decoder 12 on a main ring 10, accessed or received by the MAC 14, and advanced outward on a second ring 11. In the same way, inside connection in a station 22 is changed so that the MAC 14 can communicate only with an encoder/decoder 13. Thus, one communication path can be re-looped in the stations 20, 22 without providing a second MAC in each station.

Title: Multiplier
Inventor: ISHII MICHIO
IPC: G06F7/53
Filed: 1991-04-19
Abstract: PURPOSE:To obtain an arithmetic result at a high speed by multiplying a multiplicand by a coefficient, which accords with the state of five high-order bits of a multiplier whose 1st bit below the LSB is 0, and obtaining a partial product. CONSTITUTION:Coefficient output circuits 1 and 2 extract the five high-order bits of the multiplier X while setting the 1st bit below the LSB to 0 and output the coefficient according to the state of the respective bits. Arithmetic circuits 3 and 4 multiply the multiplicand Y by the coefficient to obtain a 1st partial product (XY)1. A coefficient output circuit extracts the five following high-order bits of the multiplicand Y corresponding to the MSB of the extracted five bits and outputs the coefficient according to the state. The arithmetic circuits 3 and 4 multiply the multiplicand by this coefficient to obtain a 2nd partial product (XY)2. Then the partial products XY are added while weighted, so the total number of full-adders (not shown in figure) decreases. Consequently, the circuit scale is reducible and the arithmetic is speeded up.

In the aforementioned method, heat treatment is carried out at a lower temperature than the synthesis temperature of a Ri- based superconductor of 110K class by 5-40 deg.C. The above-mentioned Bi-based superconductor is Bi-Pb-Sr-Ca-Cu-O-based and Bi-Sr-Ca-Cu-O-baeed superconductors and may be superconductors obtained by respectively substituting part of the aforementioned composition with other elements, e.g. part of the Sr with Ba, part of the Ca with Y and part cf the Cu with Cd. The above- mentioned synthesis temperature is a temperature at which the growth rate of the 110K phase attains the maximum in the Bi-based oxide superconductor of the objective composition. If the Pb is contained, the temperature is about 850 deg.C. In a system without containing the Pb, the temperature is about 870 deg.C. A heat-treating time of at least >=15hr is required depending on the temperature.
