摘要:
This non-volatile multi-state memory device switches a storing resolution of multi-state data corresponding to digital data stored in a non-volatile memory cell according to the data's characteristics. In more detail, digital audio data are output from an ADPCM encoder in n-bit units and m bits of address data indicating an address at which audio data are stored are output from an address controller. These are then input to a switching circuit, a bit number converting circuit converts m bits of address data to n bits of address data at the same level as the m bit data, and the converted n bits of address data and n bits of audio data are inputted to a second multiplexer. An output of the Second multiplexer is then selected in compliance with a switch signal from the address controller and either the selected n bits of address data or the audio data are sent to a read-write circuit. Consequently, for example, writing is carried out with storing resolution deemed as 16 when 4 bits of audio data are stored in an EEPROM cell array and storing resolution deemed as 2 when for instance 1 bit of address data is stored.

A superfinishing stone 2 is slid on a rotating subject surface 7 as pressed against the subject surface 7 and is held in contact against the subject surface 7 as vibrated thereon in a different direction from the sliding direction. The superfinishing stone includes plural stone portions 3, 4 divided by a split surface 6 inclined to both the sliding direction and the vibrating direction and mutually independently movable along the split surface 6 and in the pressing direction.
摘要:
The present invention provides a polycrystalline silicon conducting structure (e.g., a resistor) whose resistance value is controlled, and can be less variable and less dependent on temperature with respect to any resistant value, and a process of producing the same. Use is made of at least a two-layer structure including a first polycrystalline silicon layer of large crystal grain size and a second polycrystalline silicon layer of small crystal grain size, and the first polycrystalline silicon layer has a positive temperature dependence of resistance while the second polycrystalline silicon layer has a negative temperature dependence of resistance, or vice versa. Moreover, the polycrystalline silicon layer of large grain size can be formed by high dose ion implantation and annealing, or by depositing the layers by chemical vapor deposition at different temperatures so as to form large-grain and small-grain layers.

It is an object of the present invention to provide a light emitting device of the next generation optical device having a broad emission property that a width at half maximum of an emission spectrum is large in a wavelength range of visible light and capable of recognizing white light emitting by photoluminescence (PL). In a baking process for baking a pressure molding formed by pressure molding of silica fine particles such as fumed silica, a baking temperature is made as not more than 1000° C., hydroxyl groups of the silica fine particles are sufficiently subjected to dehydration condensation reaction so that the particles becomes transparent, a structural defect generated in the process is held without being relaxed, and thus a silica glass is generated. The silica glass is employed as a fluorescent substance.
摘要:
Volume adjustment is performed in small steps at a DSP (12) and volume adjustment is performed in wide steps at electronic volume circuits (18L, 18R). Adjustment only by the DSP (12) is performed for a small volume range less than or equal to a predetermined level. For a volume higher than or equal to the predetermined level, fine adjustment by the DSP (12) at the transient period of volume adjustment is combined to reduce the increment of variation so that the volume adjustment is performed gradually.
摘要:
A power generator system incorporates a generator driven by an engine. A case houses the generator and the engine. A controller communicates with the engine so as to control the speed at which the engine drives the generator. A temperature sensor is disposed so as to sense a temperature within the case and to send a temperature signal to the controller. The controller controls the speed of the engine depending upon at least the temperature signal received from the temperature sensor.
摘要:
A higher-performance short channel MOS transistor with enhanced resistance to soft errors caused by exposure to high-energy rays is realized. At the time of forming a deep source/drain diffusion layer region at high density, an intermediate region of a density higher than that of impurity of a semiconductor substrate is formed between the source/drain diffusion layer and the semiconductor substrate of a conduction type opposite to that of the source/drain diffusion layer. The intermediate region is formed with a diffusion window for forming the source/drain, an intermediate layer of uniform concentration and uniform width can be realized at low cost.
摘要:
A semiconductor device has an electrically insulating substrate and a semiconductor layer formed on the insulating substrate. A plurality of semiconductor regions are defined so as to be joined to each other to form at least two homojunctions in the semiconductor layer. A lead conductor for one of the semiconductor regions which is required to have a small thickness has a specific structure such that the lead conductor is in contact with the one semiconductor region at the main surface of the semiconductor layer for electrical connection therebetween and extends over that portion of the semiconductor layer which contributes to definition of at least one of the semiconductor regions other than the first-mentioned one semiconductor region.
