Abstract: PURPOSE: An apparatus of generating a CDMA(Code Division Multiple Access) signal for variable traffic situations in a communication system is provided to appropriately control a gain of a traffic signal by using one traffic signal generator, and to generate a CDMA signal. CONSTITUTION: A pilot signal generator(211) generates a pilot signal under an external control. A traffic signal generator(212) generates a traffic signal under an external control. A gain controller/signal combiner(213) converts the pilot signal and the traffic signal into baseband analog signals, and controls a gain of the converted baseband traffic signal. The gain controller/signal combiner(213) combines the baseband traffic signal with the converted baseband pilot signal to output a CDMA(Code Division Multiple Access) signal. The gain controller/signal combiner(213) highly controls the gain of the baseband traffic signal as many as a preset gain value.

Abstract: PURPOSE: An automatic constant flow and temperature control valve is provided to simplify and easily install by integrating regulating function of temperature and amount of hot water under heating system. CONSTITUTION: During the rising of indoor temperature, a contact breaking signal is transmitted form an indoor temperature sensor(30) to a valve head(20) to operate a drive instrument(40) inside the valve head. Herein, a hot wire(41) is heated to expand a heat expansion piece(43) and a proceeding section(42) of the heat expansion piece is expanded to descend an operator(44) connected therewith along a drive guide section(24). Then, the operator pushes an operating shaft(21a) of a contact breaking piece(21) to descend the contact breaking piece. A top opening section of a fixing piece(50) is closed to intercept movement of hot water to lower indoor temperature. In case of dropped indoor temperature, electrical supply of the hot wire from the indoor temperature sensor is stopped for contracting the heat expansion piece. Thus, attaching force of the operator is eliminated to force the contact breaking piece to rise up by returning force of a coil spring(21b). Moreover, the contact breaking piece continues to open and close a hot water path for maintaining an indoor temperature to a temperature established to the indoor temperature sensor.

Abstract: The invention concerns a method for treating a surface (2) of a semiconductor (1B) and a corresponding treating device. The surface is made by first molecules of the semiconductor having external bonds saturated with hydrogen. The method consists in sending a beam (30)of ions highly charged and with low energy towards the surface, and applying thereto a deceleration voltage U2 in the proximity of the surface. In this way, the ions extract without making contact the electrons of the first molecules, releasing the hydrogen atoms saturating the corresponding external bonds. Then a product saturating the pendant external bonds is sent so as to form second molecules of an insulating compound. The invention is useful for surface cleaning, etching and nano-manufacturing.
