Disclosed is a speech synthesizer integrated circuit as a preferred embodiment of the present invention, which is characterized in that;Using one chip LSI, it implements the fundamental controls for the speech synthesizing operations, for example, and fundamental controls for the key input and display operations (corresponding to the functions usually performed by any of the conventional microprocessors). The preferred embodiment of the present invention has made it possible to realize an extremely useful and versatile speech synthesizer integrated circuit by externally connecting a memory that stores the controlled programs and sound data available for synthesizing the intended speech. By allocating the same addresses to the internal and external memory storage areas, programs can be located at identical memory addresses, thereby increasing system efficiency.
摘要:
There is disclosed a one-chip speech synthesizer capable of providing synthesized human voices through a new and effective concept of LSI architecture. The synthesizer may execute all of the steps necessary for processing of sample data and enhances the processing speed through a new memory architecture by constructing the one-word length of a control memory (control ROM) longer than the one-word length of a data memory (data ROM). The synthesizer reproduces audible synthesized sounds merely by an added amplifier outside the one-chip LSI semiconductor device without the need to provide a digital-to-analog converter. The LSI device may be used with an expandable external memory as an extension of the data memory (data ROM) whenever a large number of words are to be processed.

An antiinflammatory analgesic gelled ointment comprising a phenylacetic acid type antiinflammatory analgesic agent, a carboxyvinyl polymer in an amount sufficient for gel formation, a water-soluble organic amine, a lower alcohol and water and having a pH in the range of from 7.0 to 9.0.
摘要:
The digit-capacity of display units is made smaller than that of a register storing the numeral information for indication to reduce the size and assembly cost of the apparatus equipped with the display units. To display the whole of the numeral information stored in the register, the numeral information is divided with reference to the decimal point thereof into a plurality of groups, each group being a digit number equal to the digit-capacity of the display units, and then the numeral information is displayed progressively group-to-group on the display units.
摘要:
When an error correction decoding unit 26 of a data reception device 2 fails in error correction decoding of a codeword, an MIMO processing unit 15 of a data transmission device 1 deforms transmitted codewords according to a predetermined rule, and transmits the codewords, and the error correction decoding unit 26 of the data reception device 2 reproduces data by using the deformed codewords. As a result, not only the noise but the interference wave components can be reduced, and the success rates of the demodulation and error correction decoding can be improved greatly.
摘要:
A driving apparatus includes a piezoelectric element which undergoes expansion/contraction motion by a driving signal; a driving shaft which is mounted on the piezoelectric element, and undergoes reciprocating movement according to the expansion/contraction motion of the piezoelectric element; a first movement member which is friction-engaged with the driving shaft, and moves due to the reciprocating movement of the driving shaft; and a first control portion which applies driving signals to the piezoelectric element; the first control portion applies driving control pulse signals when the first movement member is to be moved, and applies stop control pulse signals when the stopped first movement member is not to be moved to put the first movement member into a vibration-arrested state. By this means, the stopped first movement member can be smoothly moved, and the first movement member in motion can be smoothly stopped.

To provide an anodic oxidation method, a titanium oxide film manufacturing method and a catalyst carrying method which is suitable, for example, for anodic oxidation of aluminum, titanium and catalyst carrying on the surface of alumite (registered trademark), capable of generating an oxide film at a low cost and rapidly by eliminating the use of a strongly acid or strongly basic electrolytic solution and using a carbonated water as an electrolytic solution, capable of controlling the sealing treatment of oxide film through a simple method, capable of effecting the oxide film dyeing and catalyst carrying rationally and easily, and capable of effecting the catalyst carrying safely and surely without eroding a base material.An object (3) to be treated is electrolyzed in an electrolytic solution received in a treatment vessel (1) serving the object (3) as an anodic electrode.It is an anodic oxidation method in which an oxide film is generated on the surface of the object (3).A carbonated water of a predetermined acid concentration generated by dissolving a pressurized carbon dioxide in a predetermined quantity of water (7) is used as the electrolytic solution.
摘要:
For a vehicle there is provided a fire extinguisher gas ejector combined with a device for cutting a seat belt rapidly and a device for breaking open a windshield reliably to facilitate a prompt escape from a vehicle compartment in an emergency, such as a vehicle fire and collision, the fire extinguisher gas ejector includes a gas cylinder in which a seal can be broken safely and easily without necessitating a safety member for preventing seal breaking while not in use and removing operation thereof, prevents fire extinguishing gas from being wasted after the seal is broken, emits the fire extinguishing gas to a fire origin reliably and accurately, and whereby early fire extinction can be achieved. The fire extinguisher gas ejector promptly alerts people of a problem, such as a vehicle fire at night, and ensures an emergency response and safety thereof.
