Title: Method for continuously casting steel
Inventor: ITO YOICHI
IPC: B22D11/00
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To perfectly prevent the surface crack on a continuously cast slab by continuously casting a steel having a specific chemical composition. SOLUTION: This steel has the chemical composition satisfying the formular I: |Cp-0.10|>=0.02% or simultaneously satisfying the formula I and the formula II:[%Ti]/[%N]>3. In the formula I, Cp=[%C]-0.14[%Si]+0.04[%Mn]+0.70[% Ni]-0.10[%Mo]--0.438[%Nb]-0.24[%Ti]+0.70[%N]. By excluding the steel in the dangerous zone for developing the longitudinal crack by using the Cp value, the developing ratio of the longitudinal crack can drastically be reduced. The preventing effect on the longitudinal crack is remarkably obtd. by using the middle carbon steel such as 0.07-0.25% C content. Particularly, since Nb steel, V steel, etc., containing >=0.005% the total of Nb and V, are difficult to prevent the development of the traverse crack and hook-shaped crack only with the regulation of component in the formula I, these cracks are prevented by setting th formula II.  It is desirable that the surface temp. of the cast slab is regulated to >=800 deg.C in the interval from the start of casting to the completion of bending correction.

Title: Fault detector for intensive wiring system of automobile
Inventor: AKITA TOSHIYA
IPC: G08B23/00
Filed: 1983-01-20
Abstract: PURPOSE:To ensure an accurate error control by separating a certain terminal control part from the object control of a central control part when the error detecting frequency of the terminal control part exceeds a prescribed level. CONSTITUTION:The CPU of the central control part 10 receives the 1-frame data from terminal control parts 20A-20D and decides whether a BCC code contained in the received 1-frame data has no error. If it is decided that the received BCC code has an error, the CPU counts the error detecting frequency for each of control parts 20A-20D. If errors more than a prescribed frequency are continuously generated, the CPU lightens an optical push-button switch corresponding to the terminal number. In this case, the relevant terminal number is registered. Therefore the display or indication is inhibited for the data given from the corresponding terminal control part. The control subjects 40A-40D are prevented from being erroneously controlled by a faulty terminal control part accordingly.

Title: Method and device for measuring load of activated carbon filter
Inventor: BOSCHER JOERG
IPC: G01N29/09
Filed: 1987-01-19
Abstract: For determining the charging of a charcoal filter with gases and vapors the acoustical and the electrical impedance of the charcoal layer are measured. The more the filter is charged the greater will be the density of the charcoal layer and therewith its acoustical conductivity. The charging of a charcoal layer with water vapor results in an increase of the acoustical as well as of the electrical conductivity. By comparing the acoustical impedance and the electrical impedance respectively of a partially charged charcoal layer with the impedance of a non-charged charcoal layer and by subsequent comparison of the impedance changes caused by such charging the influence of water vapor can be eliminated. A signal is generated corresponding to the charging of the charcoal filter with other vapors and gases which signal may be used for indicating the condition of the filter and for generating an alarm if the filter becomes exhausted.

Then, if learning is prohibited, the previously learned error value is multiplied by the reflection gain and thereby the error of an injection amount corresponding to each running condition is calculated 11.
