IPC: G10L25/90
Filed: 1989-03-14
Abstract: A voice coding apparatus includes a pitch detecting circuit (1) which detects a pitch period of a voice signal; a pitch waveform generating circuit (2) which samples the voice signal for a plurality of pitches based on the pitch period detected by the pitch detecting circuit and which generates a waveform of one pitch from the waveform of the plurality of pitches; a band restriction circuit (3) which restricts the frequency band of the one pitch waveform generated in the pitch waveform generating circuit; and a coding circuit (4) for coding the voice 'waveform which is band restricted in the band restriction circuit. The sampling number of the waveform for a plurality of pitches and the restricted bandwidth can be changed in accordance with the amount of the pitch period extracted in the pitch detecting circuit. Further, the pitch detecting circuit is able to correctly detect the pitch period even when the pitch period is not a multiple of the sampling period.

Abstract: Because of physical and electrical limitations, buffering of the clock in a data processing system often has to be provided by two different Integrated Circuit buffers. If the clock is connected in parallel to all buffer inputs (assuming that was within the clock drive capability) the outputs of one of the Integrated Circuits may be skewed or shifted in delay time relative to the outputs of the other integrated circuit, because of the differences in the buffers. Since, however, the delay times of all the buffers on each chip are nearly the same (to within a guaranteed tolerance typically) the circuit provided by this invention will give outputs all having small and predictable skews.

Abstract: The invention relates to a method and an apparatus for the continuous measuring of heavy metals in waste gases, especially in refuse incineration plants. A sample gas stream branched off from the waste gas is first heated to a temperature of at least 700 DEG C. A liquid acid medium and tetrahydroboranate as a reducing agent are then added in succession to the sample gas stream under a suitable temperature control, so that the heavy metals, such as Hg, As, Sb and Bi, contained in the sample gas stream are converted quantitatively into elementary heavy metals and hydrides. After the gas has been separated from the liquid, the determination of the heavy-metal content is carried out in an analyser.

Abstract: A high speed CMOS binary up/down counter (10) having a 200 MHZ clock rate comprises a 4-bit counting section that may be concatenated in multiple 4-bit sections. The counter (10) performs in an up-count mode or a down-­count mode in accordance with the state of an up/down mode select signal (U/D). Each stage (11) of the 4-­bit counting section comprises a propagate/kill/generate gate (28) for determining the status of a carry signal (CO) to a next stage, except the last stage of a 4-bit section, which does not require such a gate because it is coupled to a carry-forward generator (34) along with the outputs (A₀,A₁,A₂,A₃) from the other preceding stages in the section. Each 4-bit section (10) performs the counting function through a successive process of a modulo-two sums formed by modulo-2 summers (20,22,24,26) of a lower order carry and the current state of a counter stage without the need for cumbersome gating structures. The count of each stage is stored in a D-type flip-flop (12,14,16,18). The Q or  Q  output of the flip-flop is selected by a selector (40,42,44,46) to provide the current state of the stage to the summer (20,22,24,26) in dependence upon the mode select signal (U/D).

Abstract: This invention relates to transparent films for use in graphics applications, such as, for example, visual transparencies for overhead projectors. 
     One disadvantage of presently available ink-receptive layers for transparent films for pen plotters and ink jet printers is that their high level of sorption capacity leads to poor dimensional stability, which, in turn, leads to curling of the film whenever moisture content changes, either due to imaging, or due simply to changes in humidity or to drying out due to the heat encountered on the stage of an overhead projector. 
     Curl can be reduced by applying the same image receptive layer to both sides of the film, so that any expansion or contraction will be applied symmetrically to both sides of the film. This adds to manufacturing cost, and still may not completely eliminate curl, especially in cases where moisture content differs on opposite sides of the film. 
     Accordingly, it would be desirable to provide an ink-receptive layer for transparent films that has good dimensional stability. 
     This invention provides a hydrophilic, polymeric blend which provides improved durability and reduced curl when used as an image-receptive layer on graphic arts films. The blend comprises at least one water-absorbing, hydrophilic polymeric material, at least one hydrophobic polymeric material having acid functionality, and at least one polyethylene glycol. The layer formed from the blend provides high sorption capacity combined with good physical integrity even when wet, along with dimensional stability. 
     The invention also provides sheets suitable for preparing visual transparencies having a backing bearing on at least one major surface thereof an image-receptive layer formed from the aforementioned blend.

Abstract: The invention relates to equipment to control the movement of members towards each other. In the jointing of a plastics pipe to the end of an immovable, already laid pipe length, there is a known difficulty in effecting equal trimming of the end of the pipe length and the end of the plastics pipe to be joined to that pipe length, and an equally known difficulty of applying the ends of the pipe length and pipe to a heater plate and to the same degree. This has frequently led to imperfect trimming and the creation of beads of different sizes, and which leads directly to the creation of a poor butt weld between the pipes. The object of the invention is to eliminate these problems in simple and cost-­effective manner, which object is met by a construction comprising a central support (1), a lever (2) pivotally secured to said support (1), said lever (2) extending to equal degree to opposite sides of its pivotal connection to the support (1), links (3) pivotally connected to each end of said lever, with each link (3) extending to and being pivotally secured to a respective member (4, 5).

Abstract: In a nonvolatile semiconductor memory device with a two-layer gate structure, an interlayer insulating film is formed on a floating gate electrode (13) of, e.g., polycrystalline silicon. The interlayer insu­lating film has a four-layer structure in which a first silicon nitride film (14), a first silicon oxide film (15), a second silicon nitride film (16) and a second silicon oxide film (17) are laminated in this order on the floating gate electrode. With the above structure, leakage of electrons from the floating gate electrode can be prevented by suitably setting the thickness of each film. The first silicon oxide film can be formed by oxidizing the first silicon nitride film. Thus, the quality of the first silicon oxide film can be enhanced, and accordingly the charge retaining pro­perties of the device can be increased.

Abstract: In analog communication, a transmission signal must be demodulated with good linearity. However, linearity of a reception signal is often impaired due to a too large input signal or variations during the manufacture of elements or a fluctuation in power supply voltage. According to this invention, a plurality of source-­follower circuits constituting a demodulation circuit are formed on a single semiconductor substrate, a resistor (R12) having a high resistance is connected between the gate and the source of a first FET (Q11), and another resistor (R13) is connected to the source. The gate of each of the second and subsequent FETs (Q12) is connected to the source of the immediately preceding FET (Q11), and its source is connected to the gate of the next FET. A product of a gate width of each of the second and subsequent FETs (Q12) and a resistance of the resistor (R14) connected to the source is set to be equal to that of the first FET (Q11). An operation gate voltage of each FET is set to fall within a range wherein the relationship between the operation gate voltage and a drain current linearly changes. Since the FETs are formed on the single substrate, rates of variations during the manufacture of the elements and a fluctuation in power supply voltage become equal to each other. Therefore, according to this invention, a reception signal can be demodulated with excellent linearity.
