Abstract: A bass drum 10 has a hollow cylindrical shell 11, a drumhead 12 mounted on an opening end of the shell 11 to form a striking surface, and a striking surface attachment 13 provided on the reverse side of the drumhead 12. The striking surface attachment 13 is formed of an elastic sheet. At least a part of an outer area of the striking surface attachment 13 is fixed to the drumhead 12 and a central area of the striking surface attachment 13 is not fixed to the drumhead 12. As a result, the bass drum 10 can generate a struck sound having both deep bass sound and clear attack.

Abstract: A snare drum 10 has a hollow cylindrical shell 11, a batter head 12 mounted on one end of the shell 11, a snare side head 13 mounted on the other end of the shell 11 and a snare wire 14 whose both ends are held by the both sides of the shell 11 to span across the surface of the snare side head 13. The snare side head 13 has a plurality of through-holes 13c. As a result, the snare drum 10 reduces sound volume while maintaining natural timbre and feeling of striking a snare drum.

Abstract: A tray for transporting a wafer is herein provided, which can control the temperature of the wafer upon the processing thereof, and which can easily fix the wafer without reducing the effective area on the surface of the wafer and without requiring much time for the adhesion of the wafer thereto and without requiring any post-treatment after the wafer is detached from or attached to the tray.

Abstract: Detection is made of a physical amount caused by operation performed on a mouthpiece with a human player's mouth, and a tone pitch corresponding to the detected physical amount is identified by referencing a memory storing information defining relationship between various ranges of the physical amount and tone pitches. Expected tone generating style is notified to the player based on the identified tone pitch. The memory contains a pitch table defining relationship between various ranges of the physical amount and tone pitches, and a gain table defining gain information corresponding to deviations of the physical amount from a predetermined reference point for each tone pitch and within the range of the physical amount corresponding to the tone pitch. For the detected physical amount, a tone pitch and gain information are identified by referencing the pitch gain tables, so that the identified tone pitch and gain information is notified.

Abstract: A tone generation apparatus detects a position of a mouthpiece section having been pressed by a human player holding the mouthpiece section in his or her mouth. The tone generation apparatus identifies a tone pitch on the basis of the detected position and human player's operation on a piston control. Also, the tone generation apparatus detects a pressure of breath blown by the human player into the mouthpiece section and generates a tone signal of a wind instrument having the identified tone pitch, and audibly reproduces the tone signal after amplifying the tone signal in accordance with a tone volume level corresponding to the detected pressure of breath.

Abstract: A percussion detecting apparatus capable of enhancing an effect of disturbance interception by intercepting a micro-vibration conveyed from a support frame. A pad member has a pad having a back-side surface to which a base is fixed, and a percussion sensor is disposed on a back-side surface of the base. The pad member is supported by a frame via fixing members integral with the pad member and intervening members made of silicon rubber. Vertical protrusions having different protrusion heights are formed on an upper surface of a flange of each intervening member, and horizontal protrusions are formed on an inner peripheral surface of a through-hole of each intervening member. When the pad member in an unstruck state, each fixing member is in contact with a corresponding one of the intervening members only at the vertical and horizontal protrusions of the intervening member.

Abstract: A pedal device for an electronic percussion instrument, including: a base; a foot board pivotable in a pivotable range between lower and upper limit positions; and an elastically holding mechanism for holding the foot board such that the foot board keeps an equilibrium state at an initial position within the pivotable range, the foot board being configured such that (a) when the foot board is located between the initial and the upper limit positions, it is given by the mechanism a return force having a linear characteristic with respect to a change of its pivot angle, the return force being for permitting the foot board to return to the initial position, and (b) when the foot board is located between the initial and the lower limit positions or between: an intermediate position and the lower limit position, the foot board is given the return force having a nonlinear characteristic.

Abstract: A baseplate carries on its surface a pad constituting a strike surface and a tubular rim surrounding the pad and constituting a strike ring. A pad sensor is provided on the surface of the baseplate in the central area thereof for detecting the vibration of the baseplate caused by a strike on the pad, and a rim sensor is provided between the rim and the baseplate for detecting the vibration of the rim. The electric signals representing the detected vibrations trigger the generation of tone signals of drum sounds. The baseplate is supported via vibration absorber pieces on a support frame. Thus, disturbing vibrations externally given to the support frame will be prevented from propagating up to the baseplate, being absorbed by the vibration absorber pieces.

Abstract: A drum pad capable of providing an excellent percussion feeling and securely adhering a base portion to a body portion made of rubber. The drum pad has a rear-side clothlike material which is provided on a rear surface of the body portion and into which the rubber of the body portion is impregnated. The base portion is fixed to a rear surface of the rear-side clothlike material via a fixing layer made of pressure sensitive adhesive or adhesive and provided on the rear surface of the rear-side clothlike material.

Abstract: A thin film magnetic device is provided, in which magnetic permeability in a high frequency range can be easily improved. Scratch-like grooves extending along an extending direction of a coil (for example, a Y-axis direction being an extending direction of a second coil part) are formed at least one side of a surface and a back of each of a lower magnetic film and an upper magnetic film. A magnetization direction of anisotropic magnetization is controlled in each of formation areas of the scratch-like grooves (formation areas of lower magnetic films and upper magnetic films), and therefore displacement (rotation) of the magnetization direction of the anisotropic magnetization is pinned by the scratch-like grooves. Consequently, certain magnetic permeability is kept even in a high frequency range. Moreover, such formation of the scratch-like grooves may not cause complexity in manufacturing process.
