Abstract: In a musical performance support system including a sensor device that is attached to a musical instrument and an operation device that is able to perform wireless communication mutually with the sensor device and is able to perform communication with an instructor terminal of an instructor via a server, the sensor device transmits a detection signal detected by an acceleration sensor that has at least to detection axes to the operation device, the operation device generates practice result information of musical performance of a user using the musical instrument and transmits the practice result information to the server, and the operation device receives guidance information in response to the practice result information from the instructor terminal through the server and causes display means to display the guidance information.

Abstract: The musical instrument tuner includes: a sensor device that is attached to a musical instrument; and an operation device that is able to perform wireless communication mutually with the sensor device, in which the sensor device includes an acceleration sensor that has at least two detection axes, frequency detection means for detecting, as a detected frequency, a frequency of a vibration of musical sound generated through an operation of the musical instrument based on an output from the acceleration sensor, and sensor-side communication means for transmitting transmission information including information regarding the detected frequency to the operation device, and the operation device includes operation-side communication means for receiving the transmission information transmitted from the sensor device, display means, and control means for generating tuning information of the musical instrument and causing the display means to display the tuning information based on the transmission information received

Abstract: Provided is a capo that can be operated simply and reliably. A capo includes a pair of arm members (a first arm member and a second arm member) capable of sandwiching a neck, and an electric drive mechanism that changes a distance between the pair of arm members.

Abstract: There is provided an exhaust casing for a turbocharger that can be reduced in weight and can be easily machined. The exhaust casing (1) for the turbocharger includes an exhaust casing body (2) for the turbocharger that has a hollow structure and is made of a casting of iron-based metal, a light metal layer (3) that serves as an outer shell, and a heat insulating layer (4) that is provided between the exhaust casing body (2) and the light metal layer (3).

Abstract: Provided is a strap pin fitting allowing easy attachment and detachment of a strap with respect to a musical instrument. A strap pin fitting includes: a base plate; a strap retaining portion arranged on the base plate and configured to retain a strap; a through-hole formed in the base plate and allowing insertion of a strap pin; and a presser plate attached to the base plate. The presser plate is movable between an open position where the through-hole is opened and where the operation of inserting the strap pin into the through-hole is allowed and a closed position where a part of the through-hole is closed and where detachment of the strap pin from the through-hole is prevented.

Abstract: In press forming including ironing, an elastically deformable material is used for a part of ironing die contacting to the work material under a higher pressure than designed, for taking the formed product out from the die easily in a case that the ironing die and the formed product are very close in size to each other, and thereby improving the efficiency of production.

Abstract: A simultaneous two-sided iron-deep drawing process for producing vessels such as metal cans. After being used, the cans can easily be squashed. A difference in height between the inner die and the outer die or the profile radii of the two dies are varied so as to change the longitudinal wall strength of the vessel. The work material is held between the two dies so that both sides are simultaneously ironed and thereby a tubular structure is obtained.
