Abstract: An information device is disclosed that makes it possible to simplify the operation of a user in selecting a device to be operated from among a plurality of controlled devices without any cost increase. In this device, a reception frequency indicating section instructs a frequency synthesizer to perform demodulation at a first frequency (5 GHz) first. The reception frequency indicating section instructs the frequency synthesizer to perform demodulation at a second frequency (920 MHz) when instructed from a user to select another controlled device while a menu button indicating all the controlled devices whose ID information has been detected is displayed.

Abstract: A method to easily manufacture a nanosized EuSe crystal which has been conventionally difficult to be manufactured. Heating an Eu(III) complex whose general formula is represented by the following formula generates an EuSe crystal having a particle size corresponding to the heating condition. Alternatively, the mixture composed of Eu(III) complex, a counter cation, and a solvent may be heated. The particle size of the nanosized EuSe crystals can be manipulated by the heating condition, thus the absorption wavelength of the EuSe crystals can be easily controlled. In addition, it is easy to create a magnetooptic-responsive plastic using the high dispersibility of the EuSe crystals, thus it can be immediately applied to an optical isolator or other devices.

Abstract: The present invention has been developed for providing a method to easily manufacture a nanosized EuSe crystal which has been conventionally difficult to be manufactured. Heating the Eu(III) complex whose general formula is represented by the following formula generates an EuSe crystal having a particle size corresponding to the heating condition. Alternatively, the mixture composed of Eu(III) complex, a counter cation, and a solvent may be heated. Since the particle size of the nanosized EuSe crystals can be manipulated by the heating condition, the absorption wavelength of the EuSe crystals can be easily controlled. In addition, since it is easy to create a magnetooptic-responsive plastic using the high dispersibility of the EuSe crystals, it can be immediately applied to an optical isolator or other devices.

Abstract: A groping operation apparatus is provided in which a command action can be specified by groping operation in reliable way. The groping operation apparatus includes a display device 11 having a display screen 25; a touch panel 17, which is provided on the display screen, for outputting the positional information indicating a contact point on the touch panel that is touched by the operator; specifying means 13 for specifying an action commanded by the operator touching the touch panel in accordance with the positional information; and control means 15 for outputting a control signal in accordance with an output of the specifying means. The specifying means detects the contact point moved from one end portion of the touch panel to another end portion, with the end portions located at four corner areas of the touch panel, on the basis of the positional information.

Abstract: A facsimile signal superposing system for an analog type modulated facsimile signal has been found. The present superposing system has a digital memory storing the pattern to be superposed, and the insertion circuit which has a first input terminal for receiving the original facsimile pattern, a second input terminal for receiving the output of said digital memory, and an output terminal providing the sum of the first and the second input terminal signals. The cells of the digital memory are read one after another substantially synchronized with the original picture signal, thus, a superposed facsimile signal is obtained at said output terminal. The additional pattern to be superposed is, for instance, the date of the facsimile transmission.
