  • Patent number: 9696152
    Abstract: It is possible to, with a position measuring apparatus in a NC machine tool, a NC lathe, or the like that uses a load monitoring scheme, significantly reduce a response delay on the detecting jig side than those in the conventional apparatuses, and consequently measure the position of a measurement target with high accuracy. A measurement target (e.g., an advanceable and retractable center) is caused to abut a position detecting jig at the advanced end of the measurement target. In such a state, retracting and advancing motions of the measurement target are created to increase the load torque of a feed motor to a level sufficiently higher than the load torque that is detectable by the apparatus. After that, the abutment state between the measurement target (center) and the jig is canceled to cause a sudden drop in the load torque of the feed motor.

  • Patent number: 8373056
    Abstract: In a waveform generation apparatus, a coordinates information group showing original waveform data in a two-dimensional phase space having a time axis and a wave height value axis is expanded to an n-dimensional phase space (n>2) including a time axis and a wave height value axis using Takens' embedding theorem, and converted to a coordinates information group showing attractor data. In addition, an area of the attractor data is shown, and after one of the coordinates information is specified from the coordinates information group within the shown area, coordinate values corresponding to a time axis in the coordinates information are acquired as time information. Then, composite waveform data is generated by a predetermined waveform data being added to the original waveform data, and the generated composite waveform data is outputted from a position of the original waveform data on a time axis corresponding to the acquired time information.

  • Patent number: 7626113
    Abstract: Based on the understanding that time-varying characteristics of a tone element, such as an amplitude and pitch, in waveform data acquired through a live performance of a musical instrument include a variation component intended or controllable by a human player and a variation component not intended or non-controllable by the human player, the present invention allows the two components to be adjusted/controlled separately and independently of each other, so as to achieve effective and high-quality control. Discrete variation value train is acquired for at least one particular tone element in original waveform data, and the acquired variation value train is separated, in accordance with a time constant factor, into a “swell” value train of a relatively great time constant and a “fluctuation” value train of a relatively small time constant. The “swell” value train and “fluctuation” value train are variably controlled independently of each other.

  • Patent number: 5578779
    Abstract: A tone generator clears all registers in a twenty-nine stage device so that the previous results are not used in the calculations for a next tone sample. A series approximation of a desired complex sound waveform is achieved by calculating the contributions of twenty-nine time steps back in time. Twenty-nine different address phases are respectively applied to twenty-nine stacked arithmetic units. Each arithmetic unit comprises a first adder that inputs the output of a previous arithmetic unit and the input of the previous arithmetic unit. A second adder inputs the result from the first adder and one of the twenty-nine address phases. The second adder then reads a waveform generator connected to a multiplier that is controlled by a common multiplication factor "B". The output of the twenty-ninth unit produces the desired tone without any of the stacked units feeding back any signals.

    Abstract: A musical tone synthesizing apparatus, which has a musical tone memory, generates a musical tone by accessing the musical tone memory. In ordinary state, the tone generator directly accesses the memory and generates musical tones based upon the accessed data. On the contrary, when a microprocessor directly accesses, first, an initial address to be access in the memory is set. Then, musical tone data are consecutively read out from or written in the memory by automatic increment of the address which is started from the initial set address. As a result, it is not necessary for the microprocessor to designate every address of the musical tone data to be read out or written. So, the microprocessor is not overloaded.
