Abstract: With conventional source separator devices, specific frequency bands are significantly reduced in environments where dispersed static is present that does not come from a particular direction, and as a result, the dispersed static may be filtered irregularly without regard to sound source separation results, giving rise to musical noise. In an embodiment of the present invention, by computing weighting coefficients which are in a complex conjugate relation, for post-spectrum analysis output signals from microphones (10, 11), a beam former unit (3) of a sound source separator device (1) thus carries out a beam former process for attenuating each sound source signal that comes from a region wherein the general direction of a target sound source is included and a region opposite to said region, in a plane that intersects a line segment that joins the two microphones (10, 11).

Abstract: According to one embodiment, a semiconductor device includes a lead, a frame, an optical semiconductor element, a sealing resin and a lens. The frame includes a main body covering a portion of the lead and being provided with a recess, another portion of the lead being exposed in the recess, and a casing part provided along an opening edge of the recess, the casing part including a cutout portion. The optical semiconductor element is provided in the recess and is in electrical connection with the lead. The sealing resin fills the recess from a bottom to the casing part, thereby covering the optical semiconductor element. The lens is joined to the sealing resin.

Abstract: Each word to be recognized is represented by gender-specific hidden Markov models that are stored in a ROM 6 along with output probability functions and preset transition probabilities. A speech recognizer 4 determines an occurrence probability of a feature parameter sequence detected by a feature value detector 3 using the hidden Markov models. The speech recognizer 4 determines the occurrence probability by giving each word a state sequence of one hidden Markov model common to the gender-specific hidden Markov models, multiplying each preset pair of an output probability function value and a transition probability together among the output probability functions and transition probabilities stored in the ROM 6, selecting the largest product as the probability of each state of the common hidden Markov model, determining the occurrence probability based on the selected product, and recognizing the input speech based on the occurrence probability thus determined.

Abstract: Contaminants are efficiently purified without affecting the environment or necessitating the performance of any post-treatments such as pH adjustment that would be used to prevent environmental impact, even when the contaminated soil is highly viscous. In the method of purifying contaminated soil by microorganisms according to the present invention, contaminated soil mainly comprising clay or silt and containing trichloroethylene as a contaminant is dug out, and then temporarily placed on the ground (step 101). Next, perlite 2, which is an inorganic soil-improving material, the soil-improving material, and degradation microbes 3 degrading trichloroethylene are added to the contaminated soil 1 (step 102). The contaminated soil is subsequently mixed by agitation, so as to cause the perlite 2 to absorb pore water contained in the clay or silt (step 103). Next, aeration is performed to inject air into the contaminated soil 1, thereby microbially degrading trichloroethylene (step 104).

Abstract: Signal C=[Cn−1, Cn−2, . . . , C1, C0] generated by a ring counter 1 is converted at a logic circuit 2 to a triangle pulse signal Q in which the carrier frequency of the PWM signal is equal to the frequency of the signal C raised to power of 2. The signal Q is input to the B input of a magnitude comparator 3. On the other hand, the modulation data D held by a data holding circuit 4 is compared with the converted signal Q in the magnitude comparator 3, and when the data D is greater than the signal Q, a PWM signal is obtained from the comparison result A>B. This PWM signal has no phase change and high resolution and is a low pulsating component. The resolution of the PWM signal per cycle of the ring counter 1 is held at n bits, and the carrier frequency is equal to the ring counter frequency raised to mth power of 2.

Abstract: A television receiver with a function of displaying a plurality of pictures on segmental screens, wherein pictures of registered broadcasting stations are sequentially displayed on the segmental screens in such an arrangement that actuating members in a channel selector are positioned correspondingly to the segmental picture screens, and in response to manipulation of one of the actuating members, the broadcasting station corresponding thereto is selected out of the stations being displayed in the segmental picture screens. In this television receiver, the channel selector consists of a remote control unit, and the actuating members disposed in the channel selector consist of buttons to be depressed. In the constitution mentioned, it is possible to select any desired broadcasting station with facility by a simplified manipulation while confirming the display contents of the stations instantaneously.

Abstract: A television channel selection apparatus for use with a television receiver having a number of available television channels. The television channel selection apparatus includes a pushbutton pad having a first pushbutton and a group of second pushbuttons. A television channel list is displayed on the television channel when the first pushbutton is depressed. The television channel list includes channel numbers listed in relation to the respective television channels. One of the second pushbuttons is selectively depressed to specify the corresponding channel number and thus to select the corresponding television channel.

Abstract: In a production system for performing predetermined processes on products which each have a memory incorporated therein, information necessary for those processes is sequentially written by an external computer in the memory incorporated in each product, and such information is read out from the memory and used by the production system to carry out the respective processes on the products in a low cost and efficient way.

Abstract: A deflection yoke for use with a cathode ray tube includes a pair of half-cut separators joined together to form a complete separator, a pair of saddle wound horizontal deflection coils mounted on the separator halves and a pair of toroidal wound vertical deflection coils wound about half-cut coils and assembled about the separator.
