Title: Arithmetic circuit for finite field
Inventor: AMANO YOSHINORI
IPC: H03M13/00
Filed: 1987-03-26
Abstract: PURPOSE:To obtain an arithmetic circuit for a finite field appropriate for LSI- implementation without using a ROM by successively squaring an optional element alpha<i> and successively squaring the squared result to find out alpha<(2m-2)i>. CONSTITUTION:In a 1st step, an input alpha<i> is inputted to a squaring circuit 2 through a switch 1 and its squared result alpha<2i> is outputted. From a 2nd step, the switch 1 passes the output of the circuit 2. Thereby, the alpha<2i> is inputted to the circuit 2. In the 2nd step, the output alpha<2i> of the circuit 2 is multiplied by the output '1' of a register 4 through a multipler 3 and the multiplied output alpha<2i> is inputted to the register 4. In a 8th step, after executing 3rd-7th steps, the output alpha<128i> of the circuit 2 is multiplied by the output alpha<126i> of the register 4 through the multiplier 3 and the multiplied result alpha<254i> is outputted. The result alpha<254i> is equal to the reverse element alpha<-1> of the input alpha<i>. Thus, the reverse element of an optional element alpha<i> of GF(2<8>) can be obtained from 8 steps.

Title: Quantitative analysis of mixed solution sample by titration
Inventor: TAKAHASHI AKIRA
IPC: G01N31/16
Filed: 1981-05-14
Abstract: PURPOSE:To obtain a correct analysis value in a potentiometric titration of a mixed solution sample indicating no equivalence point clearly, by deriving the solution from a linear equation concerning the relationship between an amount of addition of a titrating agent at an arbitrary time from the titration starting point to the neighbourhood of the equivalence point and the corresponding electrode potential. CONSTITUTION:When a sample indicating no clear equivalence point undergoes a potentiometric titration, for example, in measuring a mixed sample containing an acid and a ferric salt with an standard alkali solution as titrating agent solution, electrode potantials E1, E2... En (n>=2) are measured corresponding to amounts of addition VT1, VT2 ... VTn of the titrating agent solution in the titration curve before the equivalence point to obtain the linear equation for VT and (Vo+VT) 10E</>S as given by the formula. The straight line (ground plotted line) of the equation is extended to determine a value VE (corresponding to the equivalence point) at which it crosses the abscissa. All the measurements and computations are done with an automatic analyzer incorporating a microcomputer thereby affording accurate values of a quantitative analysis.

Title: Information recording medium and recording and reproducing method for its information
Inventor: FUJITA GORO
IPC: G11B7/004
Filed: 1992-02-21
Abstract: PURPOSE:To improve a linear recording density by calculating the exclusive OR of logic of recording data and the logic of an immediately before information pit hourly and outputting its result as reproducing data. CONSTITUTION:In formation 101110 is inputted to a terminal 1. A switch 6 is in a contact (b) only in a first clock period. An EXOR circuit 3 obtains '1' from the contact (b), and '0' from the EXOR of '1' from terminal 1. The output of the EXOR circuit 3 is delayed by one clock by a delaying circuit 4, and switched to a contact (a). Accordingly, to the circuit 3, second recording information (o) and the previous logical arithmetic value '0' from the delaying circuit 4 are inputted, and the output of the circuit 3 becomes '0'. Thereafter, the result 001011 of the same operation is obtained. When the output of the EXOR 3 is '1', a driving circuit 7 records a pit of 1001011 in a disk 9 by the laser of a head 8. First '1' is a dummy initial pit for determining the logic of an information pit. In this regard, at the time of '0', nothing is formed in the disk 9. By such constitution, linear recording density of the disk 9 can be improved.

Filed: 1983-04-26
Abstract: PURPOSE:To obtain an easily visible oscilloscope by constituting the whole system so that a ratio of a period in which a waveform memory is used for write is always held at a prescribed small value or below. CONSTITUTION:A display is made easily visible by always holding a ratio of a write time at a value of a prescribed small value or below. When frequency of an input signal IN is high, frequency of a write clock Q3 also becomes high, therefore, a period of t1 becomes such as <=1ms. In such a case, for instance, when a pulse width t2 of a timer 8 is set to about 100ms, write is inhibited during the following 100ms. That is a point in which a trigger occurs next to the input signal IN ought to be t10, but the trigger is delayed to t11. According to this system, a ratio of the write time becomes >=1%, and a sufficiently good picture is obtained.

Title: Manufacture of heat freed quick lime
Inventor: KOBAYASHI YOSHIROU
IPC: C05D3/00
Filed: 1981-05-15
Abstract: PURPOSE: To manufacture easily handleable heat freed quick lime having a superior effect as fertilizer without collapsing granules by adding a specified amount of water to coarse granular quick lime to slake part of the quick lime.  
     CONSTITUTION: To coarse granular quick lime in a rotary kiln or the like is added a smaller amount of water than the theoretical amount (about 32% to the amount of CaO) required to slake CaO to Ca(OH) 2  while rotating the kiln. The CaO granules are partially converted into Ca(OH) 2  by reaction with the water, and the remaining CaO mixes with the Ca(OH) 2 . Thus, the granules do not collapse, and heat freed quick lime retaining the original shape is obtd. Since this quick lime retains the granular shape, when the lime is spread as fertilizer, it is not scattered unlike powder, and it generates a smaller quantity of heat in the presence of water. Easily handleable lime fertilizer is obtd.
