Abstract: PURPOSE:To make it possible to execute fast Fourier transformation(FFT) even when the number of FFT points is reduced by serially arranging divided input data points, inputting the serial array to a reference circuit for the FFT and by-passing a specific stage from an input part. CONSTITUTION:The data of an R input obtained by dividing FFT input data points N by R (R is a cardinal number) and serially arranging the divided points is inputted to the reference circuit constituted of a data rearranging circuit part 1, a twisting coefficient multiplying part 2 and a butterfly operation part 3. The reference circuit constitutes one stage and FFT is executed by serially arranging M (M=logRN) stages. The twist operation part 2 calculates a twist coefficient for (R-1) inputs out of R inputs. The butterfly operation part 3 executes crossing operation between an input which is not multiplied by a twist coefficient and an input multiplied by the twist coefficient and by- passes K stages (K<M) from the input part of an FFT circuit consisting of M stages to execute the FFT operation of N/RK FFT points.

Abstract: PURPOSE:To make it possible to control an air-fuel ratio in a stable range around the limit of stability of an engine, in a device for carrying out the feed- back control of the air-fuel ratio in accordance with a signal from a means for detecting the transverse oscillation amount of the engine, by obtaining a compensating factor of feed-back which varies in accordance with the value of the transverse oscillation amount. CONSTITUTION:When an engine 1 transversely oscillates during engine operation, the position of a laser beam which irradiates a light receiving part 7 from a light projecting part 6, varies, and therefore, the associated photo-diode in a sensor part 10 is energized through a light transmitting passage 8, etc., in accordance with the irradiated position. Then, the sensor part 10 counts a time for the movement of the irradiated position from its original position to the above-mentioned photo-diode, and issues the thus obtained time as a sensor signal to a control unit 14 through a wave shaping circuit 13. This control unit 14 controls to increase the feed-back compensating factor of the air-fuel ratio with the sum of a proportional value and integrated value when the input signal is larger than a reference value, but to decrease the above- mentioned compensating factor with the integrated value alone when the input signal is smaller than the reference value, thereby the air-fuel ratio is controlled as previously expected.

Abstract: PURPOSE:To obtain even glow discharge for many hours and to make it possible to make a stable laser beam by a method wherein metallic electrodes in a discharge tube are constituted of a film consisting of a sintered alloy containing Cr3C2 a its main component. CONSTITUTION:As electrodes 2 and 3 are constituted of a film consisting of a sintered alloy, Cr3C2 are arranged on the surfaces of the electrodes in a particle form and the emission of electrons from the electrode surfaces is uniformly dispersed. Moreover, the electrodes regenerate CO2 gas decomposed into CO and O2 by discharge by the catalyst and adsorption action of C in the Cr3C2. Accordingly, oxidation of the Cr3C2 is hardly grown and even if discharge is continued for many hours, the discharge is stable.

Abstract: PURPOSE:To prevent the slippage between layers of a continuous business form comprising a plurality of sheets of papers bound by a stapler, at the time of printing, by providing a stacker capable of being freely turned orthogonally to the width direction of cut sheets, and a positioning means capable of setting the inclination of the turning direction of the stacker to a predetermined angle. CONSTITUTION:At the time of printing on a continuous business form 6, a switch is turned ON, and a plunger magnet 21 is excited to turn a lever 23 counterclockwise against the energization by a coil spring 24, whereby a stopper 20 is located at a left position, and a stacker 15 is moved to a position of 15'. The continuous business form 6 discharged by a discharging roller 12 is moved upward along the stacker 15', and is continuedly discharged in the state of being slightly swollen to the front side of a printer, as indicated by 6', under its own gravity. The slack corrects the slippage between the layers of the business form 6 generated at a platen part due to the sharp bending along the platen 3, thereby moderating a total winding angle set for the business form 6 by the platen 3, the discharging roller 12 and the stacker 15. Therefore, there is not possibility of staples coming off or a slippage being generated between the layers.
