Title: Method for charging raw material in bell-type blast furnace
Inventor: YAMAGUCHI YASUYUKI
IPC: C21B7/18
Filed: 1982-09-30
Abstract: PURPOSE:To make the charging of a raw material in a blast furnace uniform, by rotating a swing shoot at a predetermined speed from the discharge of the raw material to the completion of said discharge, decelerating the speed of said rotation to a specified one after the completion of the discharge, and then stopping said swing shoot in a state consistent with a position at which a port was stopped after the discharge of the raw material in the preceding step. CONSTITUTION:In discharging the predetermined amount of a raw material 11 from a stationary hopper 9 at the top of a furnace through a swing shoot 6 along a circumferential direction on a small bell 5, the swing shoot 6 is rotated at a predetermined speed from the begining of discharging the raw material to the completion of said discharge. After the completion of discharging the waw material, the speed or rotation of the swing shoot 6 is decelerated to about a tenth of an oridinary speed of rotation. After the lapse of a predetermined time, a detection signal on the position of a port at the present time is compared with a memorized signal on the stopping position of the port of the swing shoot 6 after the completion of discharging the raw material in the preceding step, so that the swing shoot 6 is stopped when both of the signals become coincided with each other.

Inventor: BABA MASAKAZU
IPC: H01J37/28
Filed: 1990-06-29
Abstract: PURPOSE:To take a highly accurate measurement by putting a conductive stylus closer to a side wall to be measured up to a distance where a tunneling current flows, and applying a voltage between the stylus and a substrate. CONSTITUTION:The stylus 211 is inserted into a hole 205 and put close to the side wall 206 to be measured, and a bias voltage 207 of about 1V is applied to monitor a flowing current 208. A piezoelectric element 202 for movement vibrates the stylus at different frequencies in an (x) and a (y) direction and a lock-in amplifier detects the vibration to discriminate between a tunneling current to a bottom 212 and a tunneling current to the side wall 206. Then the distance between the tip of the stylus 211 and the side wall is controlled to Angstrom  order to measure the shape of the side wall 206.

Abstract: PURPOSE:To prevent adjacent tracks from being superposed, by writing successively the second servo-information, while rewriting the second servo-information by a second write means until overlap indexes which have coincided with regard to both positions, respectively become approximately equal to each other. CONSTITUTION:At the time of writing the second servo-information Sb between each of the first servo-information Sa written successively in a first reference position by a first write means 20, even if a variance is generated in a second reference position for the second servo-information, this variance is corrected by a cooperative operation of the second write means 30 and a head position detecting circuit 40, and the second servo-information Sb is written in about the center between each of the first servo-information Sa at all times. In such a way, the possibility that such a trouble as tracks which are set in the center between the first servo-information and the second servo-information are superposed on each other is generated does not occur at all actually.

Title: Sweetener
Inventor: KURAMOTO TAKASHI
IPC: A23L27/00
Filed: 1979-12-28
Abstract: PURPOSE: To make a sweetener have the same sweetness as that of ordinary glycyrrhizin, no separate out or gelatinize in an acidic food, a refreshing drink, by heat- treating glycyrrhizin extracted from Licorice root with a caustic alkali solution.  
     CONSTITUTION: Hydrochloric acid is added to a warm water extracted solution of Licorice (root) so that a pH is adjusted to about 2 to give a deposit. 10N-NaOH is added to the deposit, which is made alkaline, heat-treated at 120°C for 30min, cooled, and made to separate out with an acid by using hydrochloric acid. The precipitate separated out with an acid is washed with water, dried, and extracted with an alcohol. A KOH aqueous solution is added to the extracted solution so that pH is adjusted, and the solution is crystallized from an alcohol to give a white substance. The substance thus obtained has the same sweetening strength as that of conventional glycyrrhizin but it in not used similarly with the conventional glycyrrhizin. The substance will not produce a deposit or gelatinize, when it is added to an acidic food or a refreshing drink, as the conventional products do.

Title: Nonvolatile semiconductor memory
Inventor: NOJIRI ISAO
IPC: H01L29/792
Filed: 1992-06-30
Abstract: PURPOSE:To provide a nonvolatile semiconductor memory writing and reading information surely even when the memory cell of an overerasure state is present. CONSTITUTION:A negative voltage generation circuit 30 is provided and a negative voltage generated from the negative voltage generation circuit 30 is transmitted on a non-selective word line at the time of operation of writing and reading the information of the nonvolatile semiconductor memory.

The negative voltage applied to the control gate of the memory cell transistor sets surely the memory cell transistor to an off state even when the memory cell is in the overerasure state. Then, since the information is written and read surely without being affected by the memory cell even when the memory cell of an overerasure state is present, the yield of the nonvolatile semiconductor is improved and the failure rate of the nonvolatile semiconductor memory is reduced remarkably.

Abstract: PURPOSE:To use a catalyst effectively and to obtain produced gas decomposed to a desired state inexpensively by separating a heatreceiving body to plural layers in the direction of gas stream and regulating an equivalent pore size or void of the heat receiving body at a heat radiating body side to a different value from that at a side separated from the heat radiating body. CONSTITUTION:A porous heat receiving body 4 deposited with a catalyst is separated into plural layers of heat receiving body 4a, 4b, 4c in a direction from an upstream side to a downstream side of a gas stream. The pore size of each heat receiving body 4a, 4b, 4c is arranged to be smallest in the heat receiving body 4a, somewhat larger in the heat receiving body 4b, and largest in the heat receiving body 4c, thus, the radiation absorbing capacity of the heat receiving body 4a is made larger than those of the heat receiving body 4b, 4c. As a result, the amt. of heat to be absorbed by the heat receiving body is increased at an inlet of feed gas 8, and the temp. of the heat receiving body 4a at the inlet of the feed gas 8 is elevated, so heating capacity for the feed gas 8 improved. By this constitution, the catalyst deposited to the heat receiving body 4 at the inlet of the feed gas 8 is used effectively, and produced gas decomposed to a desired state is obtd. inexpensively.
