Abstract: An electronic musical instrument has an automatic playing device which conducts an automatic musical performance at a tempo set by manually tapping of a pad before the beginning of the performance. The automatic playing device also starts the automatic performance based on the detection that the number of the tapping has coincided with the predetermined number. The tempo is set according to an interval between the successive tapping. The successive taps can be the latter two taps when the tapping is made for a number of time of music. Also, the electronic musical instrument is equipped with a tap voice output device that outputs counting voices, such as `one`, `two`, `three`, for each tapping.

Abstract: An apparatus for transporting and metering particulate material including a transport duct having an inlet, an outlet, and at least one moving surface located therebetween having a downstream facing drive surface. The apparatus further includes a motive device for moving the moving surface between the inlet and the outlet towards the outlet, wherein the particulate material becomes sufficiently compacted to cause the formation of a bridge composed of substantially interlocking particulates spanning the width of the transport duct. The bridging of the particulates causes the particulates to behave as a transient solid mass of particulates, such that the force exerted by the downstream facing drive surface upon particulates within the transport duct drives the entire mass of material through the transport duct towards the outlet. The apparatus is used to transport and meter particulate material under ambient conditions and against pressure.

Abstract: A neural modeling device comprising an electrolyte, a lipid or lipid-impregnated membrane which is situated in the electrolyte and in which an ion pump and an ion channel are buried, and an electrode for transmitting a potential of the lipid or lipid-impregnated membrane as an electrical signal. The ion pump actively transports selected ions in the electrolyte through the membrane from one side to the other side in response to an external stimulus such as light irradiation.

When this device is exposed to light, the ion pump actively transports ions to generate a potential in the lipid or lipid-impregnated membrane.
