It is constructed so as to detect a joint movement position of a robot arm by a position detector and a joint movement speed is calculated from change amounts of the joint movement position and elapsed time and is compared with an allowable movement speed and unlocking and locking of a brake are controlled so that the joint movement speed of an arm at the time of brake unlocking becomes within a constant value even when a shape, an attitude and a load condition of the robot arm vary. Therefore, movement work of the arm by the brake unlocking can be performed alone and a robot with high safety can be obtained.

A sub woofer system is constituted of a real time digital signal processing part 5 that includes an A/D converter 5a, a low pass filter block 5b, a delay block 5c, and a D/A converter block 5d, an analog power amplifier 6 and a speaker 7. The length of delay time of the delay block 5c is set so that the length of group delay time of the digital signal processing part 5 may equal an integral multiple of the length of time corresponding to one wavelength of the crossover point frequency between the digital signal processing part 5 and a main speaker 4. The signal processing is performed under the conditions that have been set as such. In this case, a construction is made up wherein the length of a group delay time produced in the digital type real time digital signal processing part can be set to a given value. By this construction, it is possible to provide a sub woofer system which can improve the phase interference between the main speaker and the sub woofer system at the crossover point between the two.

The present invention relates to a method for imparting hydrophilicity to a substrate whereby high hydrophilic properties and water-holding properties can be maintained for a long period of time. According to the present invention, an SiO2 film is formed directly or through an undercoat layer on a substrate under a reduced pressure of 100 Pa or less and immediately after the SiO2 film is formed, the SiO2 film is treated with water. Before forming the SiO2 film, it is also desirable that an undercoat layer consisting of a TiO2 film, Al2O3 film, Nb2O5 film, a laminated film prepared by laminating the TiO2 film on the Al2O3 film, a laminated film prepared by laminating the TiO2 film on the Nb2O5 film, or a low emissivity film be formed on a substrate and the SiO2 film be then formed on the undercoat film to serve as an SiO2 composite film.

In an immersion nozzle for continuous casting, at least one portion of reduced a sectional area of passage for molten metal is formed near to the bottom of the nozzle and plural discharge ports symmetrically arranged with respect to the axis of the nozzle are arranged above and below the reduced sectional area portion in the longitudinal direction of the nozzle. Further, molten metal is continuously cast by using the above immersion nozzle together with a static magnetic field.

In a stacked structure for forming a molten carbonate fuel cell according to the present invention, a plurality of unit cells are stacked, and separator elements are respectively interposed between the adjacent unit cells. First and second internal manifolds extend in the stacking direction, at both sides of the stacked structure. Third internal manifold extends at the center of the structure, in the direction of stacking. First fuel gas passages, communicating with the first and third internal manifolds, are formed at the anode side of the separator element. Second fuel gas passages, communicating with the second and third internal manifolds, are formed at the anode side of the separator element. Thus, the fuel gas flows through the first internal manifold, the first fuel gas passages and the third internal manifold, and the fuel gas flows through the second internal manifold, the second fuel gas passages and the third internal manifold. As a result, the current density distribution and the temperature distribution are uniform.

A spread spectrum controller (20) controls a PLL (10) so that the PLL outputs a spread-spectrum processed clock signal. A loop bandwidth controller (30) controls at least one of a phase detector (11), a loop filter (12), a voltage-controlled oscillator (13), and a frequency divider (14) in the PLL (10) during operation of the spread spectrum controller (20) to change a loop bandwidth of the PLL (10).
