Title: Method for accelerating aging of slag cooled slowly in blast furnace
Inventor: NAGASHIMA TAKEO
IPC: C21B3/04
Filed: 1983-01-19
Abstract: PURPOSE:To accelerate the aging of slag cooled slowly in a blast furnace by adding a surfactant combined optionally with an oxidizing agent to the slag. CONSTITUTION:A surfactant is added to slag cooled slowly in a blast furnace by >=0.005wt%. In order to produce a sufficient effect, the surfactant is added by >=0.01wt%. By the wetting and penetrating actions of the surfactant, an aqueous soln. contg. dissolved oxygen penetrates and disperses rapidly into the slag all over, so the oxidation of the slag is accelerated, and the aging is completed. When >=0.01wt% oxidizing agent is further added, the oxidizing action of the agent activates said oxidation with oxygen dissolved in the aqueous soln., so the oxidation of the slag is synergistically accelerated. A nonionic surfactant is most suitable for use as the surfactant, and an Mn compound, hydrogen peroxide, org. peroxide, an iron compound, a nitrogen compound or the like is used as the oxidizing agent.

Title: Privacy telephone system
Inventor: YAMABAYASHI MASAAKI
IPC: H04L9/06
Filed: 1990-01-16
Abstract: PURPOSE:To prevent transient noise, etc., from being erroneously recognized as a control signal such as a chirp signal by deciding whether a polarity bit to be outputted from a polarity bit extracting circuit is coincident with a bit delayed by a delay circuit or not, and making a correlation degree ineffective when the polarity bits are coincident. CONSTITUTION:The polarity bit of a received sound signal is delayed only for prescribed timing by delay circuits 46, (46-2)-(46-7). On the other hand, the polarity bit given with no-delay and the delayed polarity bit are supplied to a deciding circuit 52. At the deciding circuit 52, these two kinds of polarity bits are compared and when the result of comparison shows the polarity bits are coincident, the result of correlation degree calculation by comparing this polarity bit with a prescribed polarity pattern is made ineffective. Thus, the transient noise to be generated by rapid transition from large volume noise to a silent state, for example, can be prevented from being erroneously recognized as the control signal.

Inventor: ITOU TAKESHI
IPC: B60G21/04
Filed: 1984-01-20
Abstract: PURPOSE:To aim at improvements in steering stability, by heightening the rigidity of a suspension at a time when detection centripetal acceleration exceeds the specified value, while making the high rigidity so as to be kept up for a given period even after the said acceleration drops down to below the setting value, in case of a suspension fitted with a roll control function. CONSTITUTION:During car running, torsional rigidity control takes place, while a car speed DV and steering angle Dtheta are read out, from which estimated centripetal acceleration G is calculated with a centripetal detector 19. The operational result is fed to a judging device 20 and that whether is exceeds a specified setting value G0 or not is judged. when a car is made to be suddenly turned and steered as well as being turned and steered at car speed running, the estimated centripetal acceleration G grows large, exceeding the specified value G0. Therefore, a control signal CS is outputted out of a torsional rigidity control device 21, and rigidity in each of torsional rigidity variable stabilizers 2A and 2B is heightened in good measure. And, even if the centripetal acceleration drops down to some extent, the high rigidity state is kept up intact for a given period. With this constitution, steerability and stability are improved.
