Abstract: PROBLEM TO BE SOLVED: To suppress difference of electric potential of each part of an anode so as to surely obtain antifouling effect and also to keep durability of coating high, executing the antifouling that prevents sticking of marine organisms to a seawater intake device by using an electrically-conductive coating provided on an antifouling object surface as the anode and using a counter electrode as a cathode and thereby making direct current flow between the electrodes. SOLUTION: In the case when the antifouling of a concrete-made water passage 1 is executed, opposite both banks of the antifouling object surface are covered with antifouling electrode panels 2A and 2B in which a lining of an electrically-conductive material is applied on a surface of a metal-made plate and a lining of an insulating material is applied on a rear face of the plate, and electrodes having a relatively small surface area are provided respectively at an opposite side of each bank as counter electrodes 3A and 3B of each antifouling electrode panel 2A and 2B. Thus, sticking of the marine organisms on the surface of the anode is prevented by flowing the direct current between the antifouling electrode panels and the counter electrodes 3A and 3B of each group by using the former as anode and the later as cathode.

Abstract: PURPOSE:To increase the signal transmission speed by changing a frequency for other frequency generator while an output of a frequency generator is modulated by data and using a changeover means to select an output of the frequency generator in the stable state at the end of change. CONSTITUTION:A frequency of 1st-3rd frequency synthesizers 2a-2c is changed according to a prescribed rule under the control of a frequency designation circuit 1, that is, through the provision of frequency division data by a PLL circuit from the circuit 1. A contact of a changeover switch 3 is thrown to a position of contact 3a for times t1-t2, to a position of contact 3b for times t2-t3, to a position of contact 3c for times t3-t4, to a position of contact 3a for times t4-t5, to a position of contact 3b for times t5-t6, and to a position of contact 3c for times t6-t7. As a result, regardless of the presence of a lock time due to frequency changeover in each of the synthesizers 2a-2c, the output of the changeover switch 3 obtains a signal not affected by the lock time. As a result, the signal transmission speed is increased.

Abstract: PROBLEM TO BE SOLVED: To enhance energy transducing efficiency and to lessen radiation loss by using a high permeable magnetic member which adjusts the range and density of the magnetic flux passing a rotary heating element. SOLUTION: An excitation coil 201 generates alternating magnetic flux by the alternating current supplied from an excitation circuit and the alternating magnetic flux is introduced to a core 202 to generate eddy current in the heating layer 101 of a fixing film 1.
