Title: Reception data identification method
Inventor: OBATA KIJURO
IPC: H04B7/26
Filed: 1989-08-30
Abstract: PURPOSE:To always decide a reception data correctly by adding n-bit data weighted at every bit in response to a reception electric field strength at data reception corresponding to bits and deciding the logical value of each bit for a transmission data based on whether the addition of each bit is larger or smaller than the setting value. CONSTITUTION:A transmission side sends n-bit data for plural number of times. A control section 15 receives an i-th n-bit data from a demodulation circuit 16 upon the data reception and a reception electric field strength at that time is fetched from an A/D converter 18. Then the weight in response to the reception electric field strength at data reception is obtained and the weight is multiplied at every bit with a numeral in response to the logical value of bits forming the reception data and each n-bit data weighted at every bit is added corresponding to bits and the logical value of each bit of the transmission data based on whether the sum of bits is larger or smaller than the setting value. Thus, the reception data is correctly decided independently of the reception electric field strength at data reception.

Abstract: PURPOSE:To prevent the thermal deterioration of coke by estimating the thermal stress in the coke particles generated as a result of heating by using the predicted or actually measured temp. of the gas in a blast furnace and changing the specifications of the blast furnace operation in such a manner that the estimated value thereof attains a prescribed value or below. CONSTITUTION:The temp. distribution in the coke particles at certain time is determined by inputting the temp. distribution of the gas in the blast furnace measured actually by a measuring instrument such as vertical sonde of the blast furnace and by using the basic equation for heat transmission. The coefft. of thermal expansion is given as a function of temp. for the above-mentioned purpose, then the equil. equation determined from the balance of the forces acting on the microelements in the coke particles and the relation between the strain component and stress component are simultaneously held and are solved under the prescribed boundary conditions by which the stress distribution in the coke particles is determined. The specifications of the blast furnace operation such as blast temp. and blast moisture are changed and the conditions for the furnace inside are so controlled that the value of the thermal stress attains the prescribed value or below. The deterioration of the coke is thus prevented and the generation of the powder coke in the furnace is decreased, by which the extremely stable blast furnace operation is made possible.

Filed: 1989-09-01
Abstract: PURPOSE: To rapidly and easily tear a sealing means by one hand by tearing a skirt after a lid is removed with the assistance of a rigid gripping ring relating to a partial cut formed on an end wall of a cap. CONSTITUTION: A user fits his thumb end to a lower part of a prong 16 and upwardly pushes the same to tear two separating arms 15. Then he pulls a ring 10 to remove a tear-off lid 9 from an end wall 8, and tears a part of a cylindrical skirt 7 located between two tearing lines 12. Then the ring 10 is completely separated from a cap 5, which facilitates the removement of the cap 5 from a neck 2 of the container by the elasticity. As a plug 6 is no longer fastened by the cap 5, the user can remove the same to come close to the germ- free product preserved inside the container. According to this tamperproof sealing means, the lid 9 can be easily removed and the cap 5 can be easily torn, but the complete tightness of the container can be ensured.
