In a remote controller, a startup time or a first time duration until the startup time is input into an input unit. A timer unit counts a clock time or a second time duration. A control unit generates a signal to turn on an electrical apparatus when the second time duration reaches the first time duration, or when the clock time equals to the startup time. A transmitting unit transmits the signal. In the electrical apparatus, a main unit operates main function. A transformer supplies electricity from an external power source to the main unit through a switch. A rectifier rectifies the signal. A signal identifying unit identifies it. A reservation memory unit keeps parameter for main function. A control unit turns on the switch and controls the main unit according to the parameter when the signal is received. A battery supplies electricity to above units.

摘要:
A cleaning fluid comprising at least two components selected from organic acids, organic acid salts, electrolytes, alcohols, and water is safe. When the existing antifouling coating is to be overcoated or repaired, the surface of the existing coating is cleaned with the cleaning fluid so that a repair coating composition may strongly bond to the existing coating.
摘要:
A room temperature curable organopolysiloxane composition is provided. The composition contains a diorganopolysiloxane having at least two groups represented by the following formula (1): per molecule as its main component. In the formula, X is —R′d—NH— or —R′d—S—, R is a substituted or unsubstituted C1-12 monovalent hydrocarbon group, R′ is a C1-8 divalent hydrocarbon group, Y is a hydrolyzable group, b is 2 or 3, and d is 0 or 1. The composition has excellent room temperature curability, and the cured product has excellent moisture resistance. The composition is useful as an adhesive or sealant used at a site where hardness, water resistance, and moisture resistance are required, and in particular, for an adhesive in construction applications and electric and electronic applications where steam resistance and water resistance are required.
