Abstract: Dry powders of amino acids which exhibit great oral meltability and solubility, may be produced by spray drying a hydrous liquid of amino acids to produce a powder of amino acids, where the hydrous liquid of amino acids is prepared into the form of microfine liquid droplets in the presence of trehalose for spray drying, to obtain a powder having a mean particle size of 0.1 ?m to 15 ?m, as well as granulating and drying during the spray drying or after the spray drying, to obtain a granulated powder having a mean particle size of 20 ?m to 1,000 ?m.

Abstract: A signal waveform analysis method includes: determining a trend component of an object signal by applying a zero-phase filter to the object signal; determining an oscillatory component of the object signal by removing the trend component from the object signal; determining a wavelet scalogram by performing a wavelet analysis on the oscillatory component; and determining an oscillation period of the object signal with which the wavelet scalogram indicates a maximum. The signal waveform analysis method is employed to evaluate vehicle dynamic characteristics.

Abstract: A multilayer capacitor includes first and second internal electrodes that are opposed to each other so as to generate an electrostatic capacitance and have a capacitance generating portion functioning to generate the electrostatic capacitance, terminal connecting portions connected to corresponding external terminal electrodes, and extended portions connecting the capacitance generating portion to the terminal connecting portions. The extended portions are narrower than the capacitance generating portion and the terminal connecting portion and are curved in the direction of their thickness so as to provide a longer effective length. The multi-terminal capacitor is capable of increasing an ESR without adding a separate additional element.

Abstract: A magneto-optical disk drive in which a bias magnetic field coil is mounted on a cassette holder and movable into and out of contact with the cassette holder. A coil base carrying the coil is moved by connecting rods which are rotatably mounted on the cassette holder which is movable while receiving a cartridge therein. The connecting rods are rotated on the basis of a difference between the displacement of a body base which is stationary and the displacement of the cassette holder, whereby the coil base connected to the ends of the connecting rods is moved.

The bearing is sealed with grease seal, and grease in the bearing is prevented from flowing at a high rate by means of an annular projection extending radially inwardly from the retainer defining a small gap defined between the projection of the retainer and the inner race.

Abstract: An improved tapered roller bearing in which a shoulder at a small diameter end side of an inner race has been eliminated. A shoulder portion for maintaining a state of engagement between an inner race and a cage for holding tapered rollers at circumferentially equally spaced positions after assembling, is formed at an outer peripheral portion of a large diameter side of the inner race. Furthermore, projections for engagement with the shoulder portion are formed in positions not hindering the assembling of the tapered rollers at the large diameter side of the cage.
