    • An arteriosclerosis diagnostic device according to various embodiments is a simple device, resistant to an external factor, such as an error resulting from a skin surface, and capable of measuring the degree of hardness of an artery. The arteriosclerosis diagnostic device detects a heart sound and a pulse wave at least one location of a living body, the pulse wave propagating through an artery in relation to the heart sound, converts detected signals thereof into respective frequency signals, specifies the peak frequency of each of the frequency signals, and determines the degree of arteriosclerosis on the basis of the difference between the peak frequency of the heart sound and the peak frequency of the pulse wave. Accordingly, the degree of arteriosclerosis can be determined by comparison between the frequency signals.

    • A vehicle (approach) warning apparatus generates a warning sound that is emitted from a parametric speaker and a vehicle horn, by driving the vehicle horn with a rectangular wave signal of 0 volts or more, thereby preventing a power loss due to a counter electromotive force that is caused by an alternation of a plus electric voltage and a minus electric voltage in the horn as well as preventing a problematic distortion of the warning sound from the horn. Further, since the vehicle (approach) warning apparatus is devised to prevent the parametric speaker from generating a low pitch sound of 500 Hz that is reproduced by the horn, an influence of a higher harmonic wave upon a reproduced sound from the parametric speaker is reduced, thereby preventing deterioration of a sound from the parametric speaker.

    • The present invention is directed to serve ligand screening apparatuses, ligand screening methods, programs and a recording medium for studying the binding analysis between a receptor including an induced-fit type receptor and a ligand. First, analysis and calculation of normal mode are conducted, and then fluctuation of a dihedral angle of a main chain in a steady state is calculated. Then by carrying out a molecular dynamic calculation while imposing constraint on each atom based on the fluctuation, a dynamic structure of the receptor is predicted more accurately. By using the dynamic structure obtained in the molecular dynamic calculation and an interaction function, receptor/ligand binding which is also applicable to an induced-fit type receptor is predicted with high accuracy.

    • In a power-saving control method of an image forming device, the image forming device is set in a power saving state when an input operation is not performed by a user over a predetermined time. The image forming device in the power saving state is shifted to a minimum power state. Prior to shifting of the image forming device to the minimum power state, a filtering unit is activated to detect communication between an external device and the image forming device in the minimum power state. When a detected communication signal indicates an image formation request from the external device, the image forming device is caused to return from the minimum power state through the power saving state to a standby state so that the image forming device is ready for performing image formation.
