Filed: 1988-06-07
Abstract: PURPOSE:To generate a reverberation signal high in simulation characteristic with a simple construction by multiplying a set sinusoidal wave signal with a noise signal allowing the changing of a frequency spectrum as desired to produce an output. CONSTITUTION:When an oscillation frequency setting digital signal 111 is supplied to an oscillation circuit 1, a sinusoidal wave signal 211 is outputted corresponding to a set frequency thereof. A shift clock signal 311 for driving an M series simulated random pulse generation circuit of a noise generation circuit 2 is inputted into the circuit to obtain a simulated random pulse. A frequency spectrum of the signal can change the expanse of the frequency spectrum of an output by varying a repetition frequency of the signal 311. A pulse of the signal is used to obtain a noise signal 411. A multiplying circuit 3 performs an amplitude modulation of the signal 211 by a signal 411 to output a simulated reverberation signal 511. Centered on the frequency spectrum of the signal 211, the frequency spectrum of the signal 511 turns to a signal having an expanse of the frequency spectrum of the signal 411 in positive or negative area.

IPC: A47L9/00
Filed: 1990-06-01
Abstract: PURPOSE:To easily get over a difference in level by forming the corner portions of the tank base periphery formed by a tank base and side surfaces as slant faces. CONSTITUTION:A slant face 43 is formed on the lower corner of a tank 10 positioned between two casters 26 provided on the front of the tank 10. Accordingly, even if there is a difference in level of the floor surface, the lower portion of the tank 10 will not collide in the right-angled direction and the slant face 43 runs thereon, so that the impact force applied to the tank 10 is weakened. Thus, it is possible to prevent overturning of a cleaner main body, breakage of the tank and damage of the difference in level of the counterpart of the collision, and the cleaner can easily get over the difference in level of the floor surface.

Title: Measuring method for insulating resistance
Inventor: KIMURA HARUHIKO
IPC: G01R27/02
Filed: 1981-09-08
Abstract: PURPOSE:To shorten a measuring time by decreasing a time constant successively through a variable resistance, and thus performing automatic adjustment so that a charging current has a limit current value successively. CONSTITUTION:When switches Sa, Sb, and Sc are closed, a control current flows through a capacitor C to be tested, and the current is decreased according to the capacity of a capacitor C and the time constant depending upon a variable element resistance VR and a current detecting resistance R connected in series, so that a detected voltage passed through the resistance R is reduced. A drop in detected voltage lower than this bias voltage is amplified by an amplifier A1,  and a peak holding detector A2 controls the resistance VR to decrease the time constant successively, thus performing automatic adjustment so that the charging current which nearly has a limit current value flows successively. Once the detected voltage becomes equal to the bias voltage and the detector A2 generates a saturated output, a contact ra is connected by a relay (r) to detect a leak voltage through an amplifier A1 wherein a ground reference potential is set, thereby shortening the measurement time for the insulating resistance of the capacitor because a long time constant time is unnecessary.
