摘要:
In a musical keyboard instrument, a keyboard having a plurality of keys that pivotally move about a frame is mechanically isolated from a tone generator having a plurality of operating members allowing musical tones to be generated in response to the keys being depressed. A plurality of key-depression detection devices are arranged for the keys so as to detect the key-depression operations applied to the keys. A drive control device drives the operating members so as to generate musical tones in response to key-depression signals output from the key-depression detection devices upon detection of the key-depression operations applied to the keys. Thus, it is possible for the player, in particular, a weak person, to easily and rapidly perform key-depression operations, thus realizing desired musical performance of the musical keyboard instrument.

A key actuating system (1) of a keyboard musical instrument is provided which helps quickly push the keys by reducing reaction force with respect to force of pushing the keys during manual operation, and which supports a person having less strength to play the keyboard musical instrument. The key actuating system for a keyboard musical instrument generates a sound when a key (3) is pushed including: a pressure detection sensor (11) detecting a pushing pressure on the key; a status detection sensor (13) detecting a movement status of the key: an actuator (15) actuating the key in a pushing direction of the key; and a control portion (19), when the pressure detection sensor detects the pushing pressure and the status detection sensor detects motion of the key, controls operations of the actuator in order to maintain the detected pressure by the pressure detection sensor at a pressure threshold which is in a range larger than 0 and smaller than a pushing pressure on the key which is necessary for making a sound.

In order to provide a sound-absorbing body which has both a thin thickness and improved sound-absorption characteristics with regard to a low tone range sounds, the sound-absorbing body (1) includes: an organic hybrid sheet (2) constituted from an organic low-molecular material which is spread in a matrix polymer; and a gastight air cell (3) which is closely provided at a backside (2a) of the organic hybrid sheet, wherein the organic hybrid sheet indicates both a sound-absorption peak of a random incidence sound-absorption coefficient at a frequency band of 400 Hz or lower and another sound-absorption peak when the organic hybrid sheet is vibrated by applying air vibration caused by sound, because of adhering the organic hybrid sheet to the gastight air cell.

A fuel cell system includes a fuel cell, an auxiliary unit, a sound volume acquisition unit, and a control unit. The fuel cell supplies an electric power to a sound generating device that generates a sound. The auxiliary unit allows the fuel cell to generate the electric power. The sound volume acquisition unit acquires information that is related to at least one of the volume of the sound that is generated by the sound generating device and the volume of an environmental sound. The control unit controls the operations of the auxiliary unit, based on the information acquired by the sound volume acquisition unit.

A backscratcher which can be inserted into a space between clothes and the skin is capable of intensely scratching an itching area and has excellent usability. A backscratcher 10 has a shaft 12, a grip 11 provided at a base end of the shaft 12, a curved head potion 13 at a distal end of the shaft 12, and claws 14a and 14b branching off from a distal end of the head portion 13. The claws 14a and 14b have a substantially conical form, and base end portions thereof are integrally constructed with the head portion 13. Each tip end of the claws 14a and 14b is pointed to the extent that the end does not hurt the skin. On a base end of the grip 11 provided at the base end of the shaft 12, a hole for hooking 16 is formed. The backscratcher 10 is gripped with a hand on the grip 11 and moved with the two claws 14a and 14b at the distal end of the shaft 12 brought into contact with an itching area. Thus, the itching area can be intensely scratched with the plurality of the claws 14a and 14b.
