Title: Cleaning liquid for white dew on concrete surface
Inventor: OWA KYOSUKE
IPC: C11D7/26
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain a cleaning liquid with which white dew produced on the surface of a concrete product such as a cement brick can be rapidly, accurately and safely removed. SOLUTION: This cleaning liquid is an aq. soln. prepared by dissolving sulfamic acid, citric acid, silicon and ethylene diamine tetraacetic acid in water. Namely, sulfamic acid is a strong acid which dissolves a calcium compd. in concrete which is a strong alkali material by neutralization. Citric acid separates calcium in concrete by a chelating effect. Silicon covers bubbles (strong acid) of chlorine gas produced by the neutralization between sulfamic acid and concrete by immediately masking the bubbles produced. Ethylene diamine tetraacetic acid masks the electrolyte of white dew separated and prevents redeposition of the white dew. By allowing to proceed the chemical reaction above chemicals at one time, white dew on the concrete surface can be removed. Contaminants produced by cleaning are washed away with water.

Title: Setting device for dischargeable capacity value
Inventor: KUNO HIROMICHI
IPC: H02J7/04
Filed: 1993-10-04
Abstract: PURPOSE:To set the estimated value of an accurate dischargeable capacity even if the charging, which is not performed to full charging, is repeated. CONSTITUTION:A charging current value I is multiplied by charging efficiency (e) and a cycle time DELTAt. The result is added to a chargeable capacity Cn, and a new chargeable capacity Cn is set (S130). When a charging voltage V becomes larger than a gas generating voltage V (T) based on a temperature T of a battery, the chargeable capacity Cn (T) at the time of gas generation based on the temperature T is set as the new chargeable capacity Cn. (S170). Thereafter, the chargeable capacity Cn is operated and set with the chargeable capacity Cn (T) at the time of gas generation as the reference. When the charging voltage becomes larger the specified voltage Vset, the value of 100 (%) is set for the dischargeable capacity Cn (S230), and the charging is finished. As a result, even if the charging, which is not performed to the full charging, is repeated, the estimated value of the chargeable capacity Cn can be set highly accurately by performing the charging up to the time of gas generation.

Title: Method for continuously casting steel
Inventor: KIYOSE AKITO
IPC: B22D11/10
Filed: 1994-10-13
Abstract: PURPOSE: To produce a cast slab little in crack, inclusion and blow hole in the vicinity of the surface layer of a cast slab and high in quality by applying electromagnetic stirring generating circular flow of the molten steel in the horizontal direction and also, directing discharging direction of the molten steel from an immersion nozzle to the vertical downward. CONSTITUTION: The flow rate 4 of the molten steel flowing toward the immersion nozzle 8 from short sides 1b of a mold near the meniscus is reduced by directing the discharging direction of the molten steel from the immersion nozzle 8 to the vertical downward. That is, since the reversing flow 4 in the reverse direction is reduced in comparison with the circular flow 3 of the molten steel by the electromagnetic stirring, decelerated flow of the circular flow 3 is reduced. Therefore, since the discharged flow of the molten steel from the immersion nozzle 8 is not collided with the short sides 1b of the mold, the growth of the solidified shell is almost uniformized and the quality on the surface layer is almost uniformized.  Further, the cast slab without crack on the surface layer can be produced, and repairs in the producing process can be eliminated and also, the yield of the product is improved.
