摘要:
A superconductive logic device incorporating at least one Josephson junction comprises two superconductive electrodes, that is, a base electrode and a counter electrode with a thin insulating layer therebetween. The counter electrode has an extension for receiving an input signal and another extension connected to a ground plane. The input signal current which is supplied from the counter electrode to the ground plane acts on the Josephson junction with a magnetic field, while, a bias current is supplied from the base electrode and flows through the Josephson junction to the ground plane.

The electronic musical instrument is provided with a tone production means having tone production channels less than the total number of keys, a performance mode change detecting means, and a means for controlling tone production assignment of the tone production channels.The tone production assignment is controlled by depressed keys to one of the detecting means to produce a tone from one of the channel groups grouped according to the output of the detecting means. The selected tone production channel corresponds to the key group which the depressed keys belong to.

A lock-off switch comprises a lock plate rotatably disposed on a slider and having a projection at one side and a hole elongated in the lengthwise direction and a pin secured to the slider and loosely fitted in the elongated hole of the lock plate thereby to hold the lock plate rotatably. In the elongated hole of the lock plate a compression spring stretches between the pin and one end of the elongated hole, thus urging the lock plate toward a switch case. The slider has a stopper engageable with the projection of the lock plate thereby to stop the slider. An urging means, such as a compression spring, is provided at the other side of the slider and urging the projection of the lock plate into engagement with the stopper, thereby to prevent the slider from being pushed. To push the slider, the lock plate is rotated against the urging force of the urging means thereby to release the projection of the lock plate from the stopper.

A de-ionization treatment device includes a capacitive de-ionization treatment unit. In a de-ionization step before a regeneration step, the de-ionization treatment device injects a scale inhibiting agent into supplied water for a period of time that is deduced from a retained water amount of a de-ionization unit and a supplied water flow rate until a predetermined period of time passes or a predetermined ion concentration is reached. The de-ionization treatment device injects the scale inhibiting agent into supplied water at the time of stoppage of the capacitive de-ionization treatment unit until a predetermined period of time passes or a predetermined ion concentration is reached. Alternatively, at the time of stoppage of the capacitive de-ionization treatment unit, the de-ionization treatment device feeds a low ion concentration water in an amount based on the retained water amount of the de-ionization unit to the capacitive de-ionization treatment unit.

(In formula [1], R1 and R2 each independently represents a hydrogen atom, a halogen atom, or a C1-10 alkyl.)
摘要:
A plurality of semiconductor light-emitting elements separately emits light of each of a plurality of colors. A reference signal output section outputs a reference signal for each of the plurality of colors. A selection section selects a reference signal for each of the plurality of colors output from the reference signal output section in accordance with a light-emission timing of each of the plurality of semiconductor light-emitting elements. An operation control section, provided for each of the plurality of semiconductor light-emitting elements, holds an operation value fitted to a light-emitting characteristic of a corresponding semiconductor light-emitting element and converts the reference signal selected by the selection section by an operation. A drive section drives corresponding one of the plurality of semiconductor light-emitting elements on the basis of a signal which has converted by the operation control section.
