Title: Pre-treatment of molten iron
Inventor: FURUTA HITOSHI
IPC: C21C1/04
Filed: 1994-08-03
Abstract: PURPOSE:To execute pre-refinings such as desiliconization, dephosphorization, desulfurization, etc., without developing slag foaming by blowing CaCO3 powder on the surface of molten iron and blowing oxygen and CaO base flux into the molten iron. CONSTITUTION:The molten iron tapped from a blast furnace is charged into a torpedo ladle 1 and the powdery CaCO3 is blown at e.g. 0.5kg/min blowing speed per ton of the molten iron together with N2 as carrier gas from a top- blowing lance 2 whose tip part is apart from the surface of the molten iron by >=100mm and whose spouting hole is positioned 300mm below the upper end of the torpedo ladle 1. Further, the flux for dephosphorizing and desulfurizing such as CaO or CaF2, etc., is blown together with iron oxide powder and the gaseous oxygen from a lance 3 submerged into the molten iron. Ratio (CaO/O2) of the total quantity of CaO from both lances 2, 3 to O2 is adjusted so as to become >=1.6, and thereby, the pre-refinings of the molten iron e.g. not only the intense desiliconization and dephosphorization by oxidation without developing the slag foaming but also the desulfurization by reducing reaction can be executed at >=30% efficiency.

Title: Video signal reproducing device
Inventor: NAKAYAMA HIDE
IPC: G11B20/02
Filed: 1985-08-20
Abstract: PURPOSE:To make it unnecessary to make repeated scanning of the same track without immediately stopping picture signals from being written in plural memories even if a still picture reproducing operation is executed, but continuing said writing until the prescribed time elapses. CONSTITUTION:A still picture reproduction operating part 4 is turned on to generate a still picture reproducing command signal. Even if said signal is generated, a VTR1 immediately does not attain to a travel stop state, but continues its tape travel in the time corresponding to the prescribed number of frames. A frame control circuit 8 does not immediately stop writing in frame memories M1-M20 in response to the still picture reproducing operation, but writes data at the point when the prescribed number of frames passes from an operating point. Then the operation is shifted to a read mode, and a reproduced video signal is repeatedly read out.

Title: Sealed type alkaline storage battery
Inventor: KAWASE RYUJI
IPC: H01M10/26
Filed: 1989-07-14
Abstract: PURPOSE:To secure the capacity difference between the positive and the negative electrodes for a long period by providing a positive electrode, a Cd negative electrode, and an alkaline electrolyte including a sulfate with a reducibility. CONSTITUTION:This sealed type alkaline storage battery furnishes a positive electrode, a Cd negative electrode, and an alkaline electrolyte including a sulfate with a reducibility. As the sulfate with a reducibility, at least one of sodium thiosulfate and sodium hydrogen sulfite is used. By including a sulfate with a reducibility in an alkaline electrolyte in such a way, the oxidization of the sulfate added in the electrolyte is carried out preferentially in the positive electrode in the first charging, to prevent the progress of the charging of the positive electrode, and only the negative electrode is charged, making the charging capacity of the negative electrode sufficiently larger than the positive electrode. In this case, since the sulfate produces water as it is oxidized, the reducing alkaline density of the electrolyte shall be regulated responding to the adding amount of the sulfate.

The voltage Vcc+alpha is supplied to the selected word line 6 as the word line drive voltage. Thus, even though source voltage is lowered, the read defect due to the dispersion in the characteristic of a memory cell transistor is prevented.

Title: Method and device for detecting memory
Inventor: NIIYAMA KENICHI
IPC: G06F12/06
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To prevent the detection error of the non-mounted part of a memory by judging whether the memory is mounted at a memory mounting part or not corresponding to whether read data are coincident with first data written at the first address of the memory at the memory mounting part or not. SOLUTION: After access is performed so as to write the first data into the first address of the memory at plural memory mounting parts 1 to n of a storage part 14, access is performed so as to write second data into a second address different from the first address. Next, access is performed so as to read the data out of the first address. When the read data are coincident with the first data, it is judged that the memory is mounted at the memory mounting parts 1 to n but when those data are not coincident, it is judged that any memory is not mounted at the memory mounting parts 1 to n. Thus, the detection error at the unmounting part of the memory can be surely prevented.
