摘要:
A method of manufacturing a patterned film by which an accurately patterned film is formed when film formation is performed by using the AD method. The method includes the steps of: (a) disposing a multilayered mask containing at least one soft mask layer formed of a soft material and at least one hard mask layer formed of a hard material on a substrate or an electrode formed on the substrate; (b) spraying powder formed of a brittle material toward the substrate, on which the multilayered mask has been disposed, and allowing the powder to collide with an under layer to deposit the powder thereon, thereby forming a brittle material layer; and (c) removing the multilayered mask after step (b).

摘要:
The present invention relates to a process for producing a soy sauce koji having a reduced Busho-shu which is one of the unpleasant smells of soy sauce, and a soy sauce koji having a reduced Busho-shu obtained by this production process. Specifically, the process for producing a soy sauce koji is characterized by using a combination of a koji mold having a high isobutyric acid productivity and another koji mold having a low isobutyric acid productivity. The present invention also relates to a process for producing a soy sauce having a reduced Busho-shu and a soy sauce obtained by this production process.
摘要:
An electrophotographic image forming device is provided which includes an image holder on which an electrostatic latent image is formed. A magnetic roller has a magnetic brush including nonmagnetic toner and a magnetic carrier using a magnetic force. Donor rollers are provided which have toner layers that are received from the magnetic roller on an outer circumference of each of the donor rollers. The donor rollers are located opposite to the image holder to develop the toner onto the electrostatic latent image.
摘要:
A perovskite-oxide lamination constituted by a substrate and one or tore first films of a first oxide of a perovskite type and one or more second films of a second oxide which are alternately formed over the substrate. The first oxide has a composition expressed as ABO3, the second oxide has a composition expressed as CDO3, each of A and C represents one or more A-site elements which are one or more metal elements, each of B and D represents one or more B-site elements which are one or more metal elements, O represents oxygen, and the second oxide is unable to be formed to have a perovskite crystal structure at normal pressure without a thickness limitation. The one or more first films and the one or more second films may contain inevitable impurities.
摘要:
In an automatic player piano, hammer sensors monitor associated hammers so as to report current positions on the hammer trajectories, and a data processor analyzes the hammer motion for producing pieces of music data representative of the performance on the acoustic piano; the aged deterioration is influential in the relative position between the hammers and the hammer sensors so that the data processor rectifies the relative position, the data processor determines the turning point at which the hammer changes the direction of motion, and compares the current value indicating the turning point with the previous value; if the difference is found, the data processor adds a value of deflection of strings to the current value so as to determine and memorizes the true value of the turning point; the data processor analyzes the hammer motion on the basis of the true value so that the music data are reliable.

A key sensor-less automatic player piano includes, key actuators so as to give rise to key motion without any fingering of a human player, key sensors producing key position signals expressing key motion and a data processing unit producing music data codes during a performance on the keyboard and a playback table expressing a relation between the hammer velocity and a reference key velocity; while the data processing unit is recording the performance, the hammer velocity is estimated on the basis of a key velocity-to-hammer velocity conversion table already prepared through an experiment where the keys are depressed by a human player; while the data processing unit is preparing the playback table, the hammer velocity is estimated on the basis of another velocity conversion table prepared through another experiment where the keys are actuated by the key actuators.
摘要:
Detector detects movement of a hammer (driven member) that strikes a string (abutted member) by moving in response to operation of a key. On the basis of detection outputs of the detector and a given abutment-presuming reference value, it is presumed that the hammer has struck or abutted against the string. For example, performance event data is generated on the basis of the abutment presumption. In order to minimize errors due to variation over time or aging of a hammer action mechanism, a determination section determines that the hammer has, actually or with a high probability, reached an abutting position where the hammer abuts against the string, and the abutment-presuming condition in accordance with the determination result. It is determined that the hammer has reached the abutting position, by comparing, on the basis of detection outputs of the detector, movement of the hammer toward the string and movement of the hammer away from the string. By thus making a string-striking determination in view of operation of the hammer not only before the string striking but also after the string striking, it is possible to accurately determine whether or not the string has been struck.
