An XY plotter apparatus includes a magnetic panel, a writing tool for applying a magnetic field, a writing tool drive and an erasing magnetic field generator. The writing tool consists of an electromagnet which is arranged so that specified characters and figures may be displayed at a high speed on a magnetic panel by the writing tool. Data of a figure to be displayed is inputted into the writing tool drive so as to generate signals for position control and a signal for actuating a switch for a coil inside the electromagnet.

The speaker apparatus according to the invention is arranged in a manner that when the magnitude of an audio signal Sin increases temporarily and so a consumption power increases, a DC-DC converter reduces an output voltage Vout to thereby increase an output current Iout and further discharges a capacitor to thereby increase a current supplied to an amplifier. Thus, a power of 2.5 W or more supplied from a USB connection terminal can be temporarily supplied to the amplifier. Further, since the change of the voltage difference between the both ends of the capacitor can be made large, an amount of the electric charges discharged from the capacitor can be made large and so the size of the capacitor can be reduced.

There is provided a mode-locked semiconductor laser including a saturable absorber section, a gain section having the same composition as that of the saturable absorber section, a non-absorptive waveguide section having an absorption edge wavelength shorter than an oscillation wavelength of the gain section, an electroabsorption modulator section having an absorption edge wavelength intermediate between an oscillation wavelength of the gain section and an absorption edge wavelength of the non-absorptive waveguide section, and a distributed Bragg reflector section having the same composition as that of the non-absorptive waveguide section and including a diffraction grating. These five sections are optically coupled to one another in a single waveguide. The above-mentioned mode-locked semiconductor laser makes it possible to enhance an efficiency with which high frequency signals are applied thereto, with conditions for causing saturable absorption operation, such as a section length and a bias voltage, being kept in an optimal range.

A menu controller displays a menu of failure statuses on a monitor display. The menu controller displays a user select menu by referring to the contents of a user table storage, and controls the display attribute of the user select menu in accordance with the failure status. When a specific user is selected from the user select menu, the menu controller displays a system configuration menu showing the configuration layout of an associated user system by referring to the contents of an I/O table storage, and controls the display attribute of the constituting devices in accordance with the failure status. When a specific constituting device is selected from the system configuration menu, the menu controller displays a device information menu showing detailed information of the selected device, and detailed information.
