Title: Transparent liquid composition for oral cavity application
Inventor: TANAKA KUMIKO
IPC: A61Q11/00
Filed: 1986-06-30
Abstract: PURPOSE:To obtain the titled composition capable of keeping its transparent appearance over a long period, by compounding dextranase and an ester-type or ester ether-type nonionic surfactant having ester bond and adjusting the pH of the composition within a specific alkaline range. CONSTITUTION:The objective composition is produced by using dextranase and an ester-type or ester ether-type nonionic surfactant having ester bond (e.g. polyoxyethylene hardened castor oil) and adjusting the pH of the composition to 7.5-10 (preferably 7.5-8.5). The adjustment of the pH of the composition within the above range is effective in suppressing the decomposition of the surfactant caused by the esterase activity of lipase existing in dextranase at a small amount. Accordingly, the composition can be stored over a long period without causing clouding and precipitation in the composition and stably keeping the dextranase to effectively exhibit the sterilizing effect in the oral cavity.

Title: Air conditioner for vehicle and method therefor
Inventor: ABE KIYOSHI
IPC: B60H1/00
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To eliminate a erroneous detection and improve reliability of a switching control of an intake door by controlling the switching of the intake door based on values detected by a reducing gas sensor which is an exhaust gas sensor and has high sensitivity in reducing gas and an oxidizing gas sensor having high sensitivity in oxidizing gas. SOLUTION: A reducing gas sensor 1 which reacts well on reducing gas density to output and an oxidizing gas sensor 2 which reacts well on oxidizing gas density to output are disposed. Reference values are set in both of the sensors 1 and 2, and the reference values are compared with detected values in a comparison arithmetic processing part 3. When the one of the detected values exceeds the reference value, an intake door switching part 4 switches to inside air. When inside air should be contaminated, air can be purified by a filter and a deodorizing part 18. Thus, an erroneous detection also for contamination due to exhaust gas of a diesel powered vehicle is eliminated by the combination of the reducing gas sensor 1 and the oxidizing sensor 2 gas and reliability of the switching control of the intake door is improved.

Title: Annealing method for cold rolled steel sheet
Inventor: KOREKAWA KIMITAKE
IPC: C21D1/26
Filed: 1978-12-15
Abstract: PURPOSE:To manufacture cold rolled steel sheet excellent in moldability and low in solid solution carbon content, by heating the cold rolled steel sheet while being uncoiled, and by soaking, then by annealing the coiled cold rolled steel sheet. CONSTITUTION:A cold rolled steel sheet is heated at about 600 deg.C by a direct burner etc. without being subjected to electrolytic cleaning or removal of rolling mill lubricant. The rolling mill lubricant residued on the surface of the steel sheet is decomposed and removed. Then the steel sheet is soaked at a temp. 580-850 deg.C in an atmosphere of H2-N2, thereby reducing the oxide formed on the surface thereof. The steel sheet is coiled once again at a temp. 630-720 deg.C, and the coil is charged into an H2-N2 atmosphere and is cooled at a cooling rate, which gives product of sufficiently low in solid solution carbon content, i.e., not larger than 6 deg.C/min., to 300 deg.C, then at a rate not larger than 75 deg.C/hr. in the temp. range 300-150 deg.C. Hereby steel sheet with clean surface and excellent moldability is manufactured by annealing for a short time, without using batch type annealing furnace.

Title: Method for treating waste water for cleaning of sand filter
Inventor: KIMURA TAKAAKI
IPC: B01D29/62
Filed: 1992-06-15
Abstract: PURPOSE:To treat a large amt. of waste water by a small apparatus by a method wherein a waste water having been used for cleaning a filter layer of a sand filter is introduced into a batch-type sedimentation separating tank to perform sedimentation of suspended solid in the cleaning waste water and the supernatant water is made as a treating water and solid-liq. separation of the layer of the suspended solid is performed under a slurry condition by means of a dehydrator. CONSTITUTION:When a cleaning waste water intermittently discharged from a sand filter 1 is treated, the waste water having been used for cleaning a filter layer 2 of the sand filter 1 is introduced into a batch-type sedimentation separating tank 20 and sedimentation of the suspended solid in the cleaning waste water is performed to separate it into a layer of the suspended solid and a supernatant water. This supernatant water is discharged as a treated water and after the layer of suspended solid is discharged under a slurry condition, this slurry is carried into a dehydrator 10 to perform solid-liq. separation. Therefore, as it is enough that the sedimentation separating tank only stores the waste water generated by one cleaning, the tank vol. can be made small. In addition, as waste water is not introduced into the sedimentation separating tank until the next cleaning is started and a long standing time can be ensured, sedimentation separation of the suspended solid can be performed without adding a coagulating agent.
