IPC: F01N1/06
Filed: 1992-02-28
Abstract: PURPOSE:To provide a device muffling actively a noise consisting of plural spectra generated by an engine by outputting a second sound. CONSTITUTION:The rotational speed of the engine 1 is detected by a sensor 7 and converted into a voltage by an F/V converter 11 and inputted to a processor part 16 from an A/D 12. Sine wave data stored in the ROM of the processor part 16 previously changes whose reading interval (plural pieces exist) in accordance with the voltage value and is outputted as a reference signal. The reference signal is processed by an adaptive filter and is outputted as the second sound from speakers 5, 6 through a D/A 14, a power amplifier 15. The adaptive filter is updated successively so that the sound pressure of a microphone becomes minimum. Then, since the reading speed of the sine wave data is made variable and plural reference signals are made, plural spectra noises are muffled simultaneously with a simple system.

IPC: B21D9/10
Filed: 1981-03-24
Abstract: PURPOSE:To bend a grooved strip material easily and correctly without deforming and damaging the same in the stage of bending said material by setting spring leaves in the grooves in the working position. CONSTITUTION:Spring leaves 3a-3g of prescribed length are arrayed and set in grooves 2 around the position 4 to be bent of a grooved strip material 1 from one side 5 to the other side 6. Thence, in this state, the material 1 is bent and is passed in rolls 7-11. As a result, the inner side 5 is shrunk and the outer side 6 is extended, whereby the material is bent. In this case, the inner side 5 and the plate 3a, the plate 3 groups each other and the plate 3g and the outer side 6 back up each other respectively, and these are one body as a whole; therefore the external bending forces exterted to these act eqally to each part, thereby maintaining balance with the stresses produced from the respective parts. Hence, the local bending by the partially acted forces is eliminated and the strip material 1 is correctly bent.
