Title: Line speed setting method in continuous annealing furnace
Inventor: TAUCHI KUNIAKI
IPC: C21D11/00
Filed: 1986-12-25
Abstract: PURPOSE:To prevent for a steel plate to move in zigzag direction, by changing the line speed with the speed-time change rate obtained by a specified method in case of increasing line speed of an upright type continuous annealing furnace. CONSTITUTION:In upright type continuous annealing furnace, the steel plate 1 is suspendingly wound to a helper roll 6 to pass a heating zone 2, a soaking zone 3 and cooling zones 4, 5 to carry out annealing. In this operation, when the line speed is to be raised, the line speed-time change rate is found by the preestimating calculation for an axial temp. distribution of the helper roll in such a way that the max. temp. difference in the transient state between the center part of the helper roll 6 and the steel plate 1 is the limit value, or less, of the helper roll axial temp. difference corresponding to the heat crown limit value of the helper roll 6 which is the limit value allowing a stable movement of the steel plate 1. The set value of the line speed is changed by the obtained line speed-time change rate. Thus, the line speed is changed without the occurrence of zigzag motion of the steel plate.

Title: Method for injecting liquid into lumber, lumber, and woody composite material
Inventor: MURAKI TOSHIO
IPC: B27K3/08
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To inject liquid into lumber efficiently and economically by a method in which the lumber is compressed by pressurizing the liquid with the lumber kept at its softening point or above, the pressure of a container is reduced, the volume of the lumber is relaxed in the liquid, and the liquid is injected into the lumber. SOLUTION: Dried lumber 30 is put into a pressure container 20, after the lumber 30 being put into the container 20 in advance, the lumber 30 is immersed in liquid L which was introduced into the container 20. Next, the liquid L in the container 20 is pressurized by a liquid supply pump 13, the pressure of the container 20 is increased, and the lumber 30 is compressed by the pressure applied to the liquid L in the container 20 or by the hydrostatic pressure of the liquid L. Next, part of the liquid or part of pressurized gas in the container 20 is discharged to decrease the pressure of the container 20. In this way, the lumber 30 experiences the volume relaxation phenomenon and tries to regain the initial shape, suction force is generated in the process, and the liquid enters the tissue of the lumber.

Abstract: PROBLEM TO BE SOLVED: To make the total amount of raw water added with hydrochloric acid to be a raw material be produced as a disinfectant having a high sterilization effect by passing raw water added with hydrochloric acid through an electrolytic bath without a diaphragm between positive and negative electrodes and electrolyzing the raw water by passing current between the electrodes. SOLUTION: Raw water W in a raw water tank 1 is introduced from a raw water sending pipe 2 into an electrolytic bath 5. In this process, hydrochloric acid A of relatively high concentration is injected into the water W to make the water W in the bath 5 hydrochloric-acid-added raw water AW of a given concentration. In this state, the electrodes 7 in the bath 5 are energized for electrolysis. Since liquid reduced by the cathode and liquid oxidized by the anode are mixed always in the bath 5, the pH of the water remains almost unchanged by the electrolysis. The water AW is converted into electrolyzed liquid E with a strong oxidizing effect by the anodic oxidation, which is discharged from an electrolyzed liquid discharge pipe 8 as a low pH disinfectant having a strong sterilization effect.
