Abstract: There is provided a method for a computer to perform evaluating rapid chord playing and/or tonality based on performance actions of a performance; and instructing, during the performance, an outputter to output a reaction sound corresponding to the evaluation.

Abstract: An additive for boiled rice that is used to avoid the lowering of efficiency at boiling for boiled rice or the like and to obtain a boiled rice of high quality presenting soft texture which is free from drying and sogginess resulting from moisture transfer during the storage thereof. There is provided an oil-in-water emulsification composition comprising a water soluble polysaccharide derived from soybean. High effect can be realized by the use of a water soluble soybean polysaccharide with a certain level or more of emulsifying capacity, and striking effect can be realized by the use of an emulsification composition comprising this polysaccharide with high emulsifying capacity combined with a polysaccharide having a certain level of viscosity even if its emulsifying capacity is poor.

Abstract: Legume-derived, and particularly soybean-derived, water-soluble polysaccharides are added to thickener-containing powder supplied with an instant food to prevent clumping of powder masses during reconstitution and for a more homogeneous reconstitution. Thus, the problem is solved which is encountered with soup powders such as a thickened soup powder and a curry-seasoned soup powder, which are supplied with instant foods such as instant noodles, containing thickeners such as starch or gum substances to impart thickness, whereby reconstitution in a stationary state produces swelling of the thickener and prevents adequate dispersion, resulting in scattering of powder masses in the soup and clumping at the bottom of the container and, thereby, impairing the taste.

Abstract: A dancer roll device has a support assembly that supports a roll. A ball screw is rotatably mounted on the support assembly. A weight member is mounted on the ball screw by a nut member that is threaded over the ball screw. When the ball screw is rotated about its own axis by a motor, the nut member and the weight member are displaced along the ball screw, thereby displacing the center of gravity of the support assembly. The moment applied to the roll is changed, thus changing the tension that is applied to a wide web or a narrow web via the roll.

Abstract: A measuring apparatus has a magnetizing head for magnetizing a magnetic layer of a specimen, and a detecting sensor for detecting a magnetization of a magnetized area which has been magnetized by the magnetizing head. The magnetization detected by the detecting sensor is supplied via a sensor amplifier to a controller. Based on the supplied magnetization, the controller determines the thickness of the magnetic layer from a magnetization to magnetic layer thickness conversion table or formula. The thickness of the magnetic layer can therefore be measured accurately in a short period of time.

Abstract: The tension on a tape web is controlled with a lock mechanism in an apparatus wherein a first dancer device, a pair of engaging-disengaging rolls, a second dancer device, and a pair of nip rolls are located in this order from the upstream side to the downstream side in the direction along which the tape web moves. The speed at which the engaging-disengaging rolls rotate is adjusted on the basis of the vertical position of a dancer roll of the first dancer device, and the speed at which the nip rolls rotate is adjusted on the basis of the vertical position of a dancer roll of the second dancer device, whereby the tension on the tape web is adjusted.
