An organic electroluminescent display device includes an organic electroluminescent element formed on a substrate thereof and having an organic compound layer group sandwiched between cathodes and anodes. The organic compound layer group has laminated electroluminescence functional layers formed of at least one kind of organic compound. Further, the organic electroluminescent display device includes an airtight case that encloses the organic electroluminescent element with a space formed between the airtight case itself and the organic electroluminescent element and isolates the organic electroluminescent element from outside air, and a filler gas filling the space within the airtight case. The filler gas contains at least one kind of combustion supporting gas.

A digital audio signal recording and reproducing system employs a recording method which can function for a reproducing apparatus of a low price satisfying the performance of the conventional standard and also an expensive reproducing apparatus of a high sound quality which satisfy the standard of the Super CD featuring a wide band, a high sound quality, and multi channels. The recording apparatus divides recording audio signals into a plurality of frequency components and produces data for recording, respectively. Further, the recording apparatus adds identification data indicative of a frequency band of each of the data and records the resultant data. The reproducing apparatus selectively extracts each of the above data by means of the identification data and performs the reproduction of the extracted data.

An apparatus for driving an electroluminescence device by supplying an alternating current to the electroluminescence device, the apparatus having: a direct voltage source; a constant voltage control device for generating a direct current having a constant voltage on the basis of an output of the direct voltage source; a constant current control device for generating a direct current having a constant current on the basis of the output of the direct voltage source; a selecting device for selecting either one of the direct current having the constant voltage and the direct current having the constant current; and a converting device for converting the selected direct current to the alternating current to be supplied to the electroluminescence device.
摘要:
An organic electro-luminescent element is provided with a drying substance contained in an airtight container and spaced from the element in an internal space of the airtight container for absorbing moisture in the internal space. The drying substance comprises a solid compound which chemically absorbs the moisture and maintains its solid state even after absorbing the moisture.

There is provided a loading/ejecting mechanism which comprises a moving mechanism for engaging with a cassette and for moving the cassette between an inserting position and a reproducing position. A sliding member is capable of applying a driving force to the moving mechanism so as to cause the moving mechanism to move between the inserting position and the reproducing position. A first gear is driven by a motor and provided such that in a cassette loading operation, the first gear engages with the sliding member thereby causing the sliding member to move in the loading direction. A second gear is driven by the first gear and provided such that in a cassette ejecting operation, the second gear rotates in an opposite direction to the first gear. A third gear is provided coaxially with the second gear and adapted to rotate in the same direction as the second gear, such that in the cassette ejecting operation, the third gear engages with the sliding member, thereby causing the sliding member to move in the ejecting direction.

A mode control ring having cams for operating various devices in a cassette tape recorder is rotatably mounted on a base plate. A normal pinch device and a reverse pinch device are mounted on the base plate. Each of the pinch devices comprises a capstan, a pinch roller provided on a swing lever so as to be engaged with the capstan, and an idler provided to be engaged with a reel gear. A power transmitting devices is provided for transmitting a driving power from a motor to each capstan. The normal pinch device, reverse pinch device are disposed along the circumference of the mode control ring, and each swing lever is arranged so as to be moved in the radial direction of the mode control ring. Selective operation of these devices is controlled by the rotatably mounted mode control ring, which has various cams formed on its inner peripheral surface, on its outer surface, and as grooves therein, which are engaged with cam following members of the devices.

A butterfly damper for preventing an adhesion surface between a speaker frame (6) and an outer peripheral frame (12) from peeling off is provided. The butterfly damper comprises an inside peripheral flame (11), an outer peripheral flame (12) and a plurality of movable arms (13), all of which are formed in a single piece by injection molding of thermoplastic synthetic resin. The thickness T of the outer peripheral flame (12) is thicker than the thickness t of the movable arms (13). In addition, the front and back faces of the outer peripheral flame (12) are formed so that each face protrudes toward the thickness direction respectively from the front face and the back face of the movable arms (13).
