Title: Galois field multiplying circuit
Inventor: IWAMURA KEIICHI
IPC: H03M13/00
Filed: 1986-10-07
Abstract: PURPOSE:To enable multiplication on a Galois field with a small amount of circuits without using a ROM by using the face that (x), (y), and (z) have specific relations with respect to a (x) and (y) on a Galois field GF2<m>. CONSTITUTION:In case of a multiplying circuit on GF2<8>, the value of (y) is multiplied by 1-alpha<7>, and outputs are allowed to pass through if x0-x7 are '1', and outputs are set to 0 if x0-x7 are '0', and EXOR of respective outputs is operated to generate (z). A selector 3 is first set to the (y) side for the purpose of successively multiplying (y) by alpha, and (y) is taken into a register 1, and AND between the output and x0 is operated by an AND circuit 5 to output y.x0. This output and the output of a cleared register 2 are taken into an EXOR 6. Next, the selector 3 is set to the alpha circuit side, and the result obtained by multiplying the output of the register 1 by alpha is taken into the register 1, and AND between this output alpha.y and x1 is operated to output x1(y.alpha). This output and the output x0.y of the register 2 are allowed to pass the EXOR 6 to take an output x1.(y.alpha)+x0.y into the register 2. The same operation is repeated up to x7 to reliaze a formula of (z).

Abstract: PURPOSE:To improve the use efficiency of a memory by using a single ROM space and making it possible to transfer its contents to another memory space to reduce the number of evaluating chip terminals and increase of the area at a program developing time. CONSTITUTION:A decoder 9 decodes a program stored in an instructin ROM6, where programs and fixed data required for operations are stored, and gives commands to an operating device 10 or a data transfer device 11. That is, fixed data of a required number of words is stored in the ROM6 preliminarily and is transferred to a data RAM(B)8 by the device 11, and thus, programs and fixed data required for processings can be stored in the single ROM space. As the result, it is sufficient if only this single space is substituted with an external RAM at the program developing time, and the number of terminals of evaluating chips and increase of the area are reduced to improve the use efficiency of the memory.

Abstract: PROBLEM TO BE SOLVED: To degrease and wash the entire part of steel strips by subjecting the cold rolled steel strips to alkaline washing and rough washing with hot water, then subjecting the parts of the steel strips stagnating in a washing tank by welding of the steel strips to high-pressure hot water washing. SOLUTION: The cold rolled steel strips 1 are subjected to alkaline washing by jetting of an alkaline washing liquid in an alkaline washing tank 2 and brush rolls 4 and after the washing liquid of the steel strip surfaces are wrung by wringer rolls 5, the steel strips are subjected to rough washing by jetting pressured hot water in a hot water rough washing tank 6. The alkaline soln., oil-component and stains remaining in a high-pressure hot water washing tank 9 are washed and removed. In such a case, the discharge pressure of the hot water from spray nozzles 10 are set at 2 to 20MPa in the stationary parts of the steel strips and welding is started after the steel strips stop for the purpose of welding the steel strips. The pass of the welding point is detected by an optical sensor 12 while the welding point passes the inside of the high-pressure hot water washing tank 8.  The discharge pressure of the spray nozzles 10 is adjusted to 25MPa by a hot water pressure control section 13 and the speed of the steel strips is lowered, by which the stains during the stop of the non-stationary parts are completely removed and washed.

Title: Gate turnoff thyristor
Inventor: KIRIHATA FUMIAKI
IPC: H01L29/74
Filed: 1986-10-08
Abstract: PURPOSE:To decrease a turnoff loss without a turnon voltage and a reverse leakage current increased, by decreasing carrier implanting efficiency of the fourth layer and suppressing an increase in turnon voltage by the use of the fourth layer part of high impurity concentration and improving a current share of each primary layer. CONSTITUTION:A surface impurity concentration of a p-emitter layer 2 is made lower than that of a conventional element, and an inner surface of the layer 2 keeps in touch with the whole surface of a n-base 3 and so a pn junction is formed. Most parts 21 on this p-emitter layer 2 of low impurity concentration keep in touch with an anode electrode 6 on the main surface side of a substrate 1. Because a surface impurity concentration of this anode touching part 21 is low, hole implanting efficiency decreases compared with a conventional GTO. Therefore, a turnoff loss is lowered. Insular p<+>-emitter layers 9 of high impurity concentration, which do not attain to the n-base layer 3, are formed on the p-emitter layer just under a n-emitter layer 5. Hence, a large increase in turnon voltage due to the p-emitter layer 2 of low impurity concentration can be suppressed.

Title: Digital controll phase locked loop circuit

IPC: H03L7/089
Filed: 1990-09-10
Abstract: PURPOSE: To remove noise by restricting sauce and sink bar signals for holding time, driving a charging pump only at the off of a 1st transmission gate and suppressing the entry of noise generated from the pump to the negative input of an operational amplifier. CONSTITUTION: The charging pump 36 selectively charges/discharges a capacitor 38 with electricity. All control input signals to the pump 36 are generated during the period of a 2nd clock signal PH2. Thereby the voltage of the capacitor 38 is settled before the start of a 1st clock signal PH1 in which the voltage of the capacitor 38 is sent to the inverted input of an operational amplifier 54 in a loop filter 42. Thereby the entry of noise generated by the pump 36 to the inverted input side of the amplifier 54 can be effectively suppressed. Thus noise in a PLL circuit 100 can be remarkably reduced.
