    摘要: A large scale integrated circuit chip is provided with internal tone generators and digital attack and decay features interconnected with external capacitors for controlling the attack and decay of tones. External diodes are wired to the chip and to the external capacitors and have a circuit completed by a damper switch. According to the position of the switch the capacitors will discharge slowly for long sustain of tones, or will discharge very rapidly through an additional discharge path on the chip upon key release to produce very rapid decay.

    摘要: An aquarium filter arrangement including a filter housing and a filter cartridge positionable within a filter chamber of the filter housing. The filter arrangement includes a hinged cover connected to the filter housing. The hinged cover is designed to collect condensation when the cover is in an open position, and empty the collected condensation into the filter chamber when the cover is closed. The filtering housing also includes guides located above the filter chamber. The filter cartridge can be positioned within the guides during maintenance of the aquarium.

    摘要: A non-volatile memory system for an electronic musical instrument having a plurality of player actuatable instrument controls, comprises a readable, writable memory. The memory includes addressing inputs and data input/outputs. The data input/outputs are coupled with at least selected ones of the plurality of player actuatable instrument controls. Player actuatable memory controls are also provided for selecting either the memory or the selected ones of the player actuatable instrument controls for control of the instrument.
