Title: Method for manufacture of lithographic plate by silver salt diffusion transfer method
Inventor: POORU KOPAN
IPC: B41N3/08
Filed: 1994-02-07
Abstract: PURPOSE: To extend the life of rinse water ecologically and economically and easily by adding a specified alkali to the rinse water before rinsing the exposed and developed image forming material or within a specified time of using water. CONSTITUTION: The alkali is added to control a pH in 10.5-13 before rinsing the exposed and developed film-forming material before using at most <=20m<3> and/or before using water for 24 hours. When the rinse water is not restored up to 10.5 in pH quickly enough, reuse of the rinse water is regulated because of occurrence of offensive odor. It is preferable that the alkali is added before rinsing 10m<2> of the developed material in order to keep it in the range limits and to control it in a pH of 11.3-12. The alkali compound to be used is sodium hydroxide and potassium hydroxide and the life of the rinse water is extended by further adding the alkali to keep it to 10.5-13, preferably, 11.3-12.

Title: Carbonation-suppressant for concrete or mortar
Inventor: MATSUDA JIYOUHEI
IPC: C04B41/62
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To obtain a safe carbonation-suppressant excellent in processability as well as properties and quality. SOLUTION: This carbonation-suppressant is a basic organic acid aluminum salt with basicity of 10-75% and exhibits an excellent carbonation-suppressing effect e.g. through dipping itself for 10sec.-30min. or spraying itself to concrete or mortar in a state of the 0.5-20wt.% solution if applied as a solution and is excellent also in safety in processing because of aluminum salt. If an organic acid of the basic organic acid aluminum salt is lactic acid or a mixture of lactic acid with an organic acid other than lactic acid (where the molar ratio of the organic acid other than lactic acid/lactic acid is 0.1-2.4), the carbonation- suppressant exhibits especially excellent effect on concrete or mortar. In addition, the carbonation-suppressant is extraordinarily excellent in low price and easiness to produce.

Inventor: BURAIAN UIRIAMU HAMONDO
IPC: F24H1/22
Filed: 1992-01-28
Abstract: PURPOSE: To obtain a simple and reliable heater for liquid by providing control means for operating an electrically operated valve and a heating means independently. CONSTITUTION: When the water level reaches the level of a sensor 28, a valve 22 is closed by a first control means C1.

Consequently, when the temperature sensor 29 senses a cold liquid, the heating element 12 is operated by the second control means C2 in order to heat the water in a container 11 and the heating element 12 is stopped when the sensor 29 senses a hot liquid.
