Inventor: NAKATANI TATSUO
IPC: B63B1/34
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To decrease fluid frictional resistance and to prevent microorganisms in water and org. substances from sticking by a method wherein a hydrophobic fine uneven face with gas holding properties is formed on the immersed surface of a structure and a gas film forming gas mixed with oxidative gas or liq. is fed thereto to hold a gas film. SOLUTION: A face consisting of a fine uneven face wherein at least projected parts are hydrophobic and with gas holding properties is formed on the immersed surface of a structure such as ships and bridge legs with a part to be immersed in water contg. org. substances and microorganisms such as water for specified uses and sea water. This gas holding face is formed e.g. by a method wherein an uncured resin layer is formed on the surface immersed in water and fine particles are scattered thereon to cure the resin. In addition, a gas for forming the gas film mixed with an oxidative gas or liq. is fed to the upstream side in the direction to which a gas constituting the gas film on this gas film holding face is taken away by buoyancy, water flow, etc., to give oxidative force to the gas film. As this oxidative gas, chlorine or ozone is pref. used.

IPC: G05B23/02
Filed: 1978-06-28
Abstract: PURPOSE:To secure an easy detection for the fault of the control system by memorizing constantly both the target signal and the feedback signal into the memory circuit, comparing these signals to obtain the difference and then deciding the code of the value obtained by differentiating the absolute value of the difference. CONSTITUTION:The target value given from integrating circuit 13 plus the feedback displacement signal given from displacement detector 16 are memorized in analog memory 26 and 27 each in the servo-control system such as the vibration board control unit or the like. The output of memory 26 and 27 are supplied to comparator 28 where the difference of both output is delivered to be supplied to absolute value detection circuit 29. Thus the absolute value is obtained, and furthermore the increment and decrement of the absolute value is obtained at differential circuit 30. In case the control system functions normally, the output of circuit 29 shows a monotonous decrement. As a result, the output signal of circuit 30 becomes negative. With occurrence of the fault, the output signal of circuit 30 changes positive. Thus the code of the output signal of circuit 30 is decided at code decision circuit 31, detecting the presence or absence of the fault.

Abstract: PURPOSE:To obtain an IC card having no possibility that a contact may be separated from a battery when some frequency is applied to the IC card and result in the interruption of an electric power supply to an electric circuit by a method wherein two contacts are provided on one pole of the battery, and these contacts are equal in width and thickness and different in length. CONSTITUTION:When a resonant frequency with respect to a natural frequency of one negative electrode contact 5a is applied to an IC card, the negative electrode contact 5a separates from a negative pole 2 to come to non-contact state. However, the other negative electrode contact 5b free from resonance has no possibility of separating from the negative pole 2 and, thus, an electric power supply to an electric circuit is ensured through the negative electrode contact 5b. When a frequency generating a resonance with the negative electrode contact 5b is applied to the IC card, the other negative electrode contact 5a has no possibility of separating from the negative pole 2 and, thus, an electric power supply to the electric circuit is ensured through the negative electrode contact 5a. One of the negative electrode contacts may be made larger in width as an alternative to differing in length. A similar effect can be also obtained by varying in thickness.
