Abstract: Endotoxin is detected by electrochemical measurement. A detection device 15 of endotoxin detects endotoxin contained in a fluid to be tested (for example, a dialysate) specifically in the following manner. First, the fluid to be tested is brought into contact with an adsorbent 17 that adsorbs endotoxin to cause the adsorbent 17 to adsorb the endotoxin. Then, a basic solution is brought into contact with the adsorbent 17 to desorb the endotoxin. Electrochemical measurement of the basic solution containing the desorbed endotoxin is performed. The endotoxin can be detected by the electrochemical measurement with high sensitivity at low cost.

Abstract: An ultrasonic cleaning apparatus and an ultrasonic cleaning method for an edge face of a substrate help prevent re-contamination caused by splashing or the like of ultrasonic wave propagating water sprayed onto an edge face of an object to be cleaned. An ultrasonic wave transmitting tube provided to continue from the spot shower and configured to transmit and spray the ultrasonic wave propagating water to the substrate is provided, the ultrasonic wave transmitting tube is installed so as not to be positioned on the substrate, the substrate is retained so that the surface of the substrate assumes a horizontal state, and ultrasonic wave propagating water is sprayed to the edge face, which constitutes an outer periphery of the substrate arranged in a space from the ultrasonic wave transmitting tube in a direction of tangent line of the edge face while rotating the substrate by a rotatable rotation retaining portion.

Abstract: The CPU in a music score display device includes: a source region setting unit that sets a source region based on a desired portion designated in a music score displayed on a screen, the source region of the music score being an object to be enlarged and displayed; a display destination region setting unit that sets a display destination region of the screen, the display destination region corresponding to the source region; and a display control unit that extracts the music score in the source region, and enlarges and displays the extracted music score in the display destination region on the screen.

Abstract: A musical-score performing apparatus is provided. In the apparatus, a musical-score displaying unit with a displaying screen displays a musical score of music on the displaying screen, the musical score being represented by a form of multiple staffs, and a designating unit is used to designate a position on the displaying screen of the musical-score displaying unit. A play-back controlling unit plays back the music represented by apart or the whole of the multiple staffs of the musical score in accordance with the position designated on the displaying screen.

Abstract: A music playing movement display control device 1 includes CPU 11 that creates a time list including respective times and a time in advance of the respective times during a musical performance, based on music playing information. The CPU 11 draws on the display unit 16 a movement image of a finger showing a pressed key position on a keyboard at the respective times and a movement image of a finger showing a pressed key position on a keyboard at the times in advance to the respective times for each of the respective times during a musical performance, based on music playing information, movement information, keyboard data, structure data, and a time list.

Abstract: An object of the present invention is to provide a method for controlling microorganisms in food materials, by which bacterial groups that cause deterioration of the quality of food materials such as poultry and pathogenic microorganisms that cause food poisoning can be efficiently controlled. Specifically, the present invention relates to a method for controlling microorganisms in food materials, comprising a step of subjecting a food material immersed in a sterilizing solution to repeated treatment with negative pressure and ordinary pressure and/or a step of subjecting the food material immersed in the sterilizing solution to resonant ultrasonication.

Abstract: A second housing whose center portion is depressed and whose end portion around the center portion is formed like a visor is arranged around a first housing whose center portion is depressed and whose end portion around the center portion is formed like a visor, and a hollow portion is formed between the first housing and the second housing by sandwiching a packing between the end portions of the housings. Further, degassed water for preventing empty heating is filled in the hollow portion, and an ultrasonic transducer is placed on the surface of the center portion of the first housing. A weight for preventing the vibration of the wall is provided on the wall surface of the second housing. Since the vibration of the wall of the housing is suppressed by the weight, vibration energy returns toward the bottom surface of the center of the housing through water and is radiated from the bottom surface efficiently as ultrasonic waves.
