Title: Vacuum cleaner suction head for floor
IPC: A47L9/02
Filed: 1992-03-25
Abstract: PURPOSE:To prevent invasion of excessive current into a motor by a method wherein an operation part to contact with a floor surface when a suction head is placed on the floor surface is changed over from a neutral position to an advancing or a retreating position whenever the suction head advances or retreats, and rotation of the motor is reversed accordingly. CONSTITUTION:An operation part 15 is provided, which comes into contact with a floor surface when a suction head body 1 containing a driving wheel and a rotary brush to be driven by a driving motor is placed on the floor surface. The operation part 15 is formed of an operation lever 17 in a casing 16, an advancing switch 18, a retreating switch 19 and a return spring 20. When the suction head body 1 is placed on the floor surface, the operation lever 17 takes a neutral position. If the suction head body 1 is advanced or retreated (an advancing is shown in the drawing), the operation lever 17 comes into contact with an advancing or a retreating switch 18 or 19. When the operation lever 17 is switched between advancement and retreatment, a neutral state in which no power is supplied to the motor appears temporarily, and then the current flowing direction in the motor is reversed. By this, an invasion of an excessive current into the motor can be prevented, whereby a rectifier for a power source can be protected from being damaged.

Abstract: PURPOSE:To obtain a uniform and stable planar corona discharge between electrodes and to improve ozone generation efficiency by connecting the respective phase output terminals of an n phase AC output device in earlier order of their phases to discharge electrodes in clockwise or counterclockwise order. CONSTITUTION:This polyphase AC multielectrode corona discharger includes the n phase AC output device outputting n phase AC and an electrode unit arranged in proximity with the front ends of discharge electrodes T1 to Tn near the respective vertexes of a regular n-gonal shape and is formed by connecting the respective phase output terminals of the n phase AC output device in the order of the earlier phases to the discharge electrodes T1 to Tn of the unit in clockwise or counterclockwise order. This device is installed within an ozone generating column in which oxygen or oxygen-contg. gas flows.

IPC: H04N19/50
Filed: 1986-05-06
Abstract: PURPOSE:To quickly attenuate the influence of mistaken transmission and to coexist a high picture quality and a high anti-transmission error by adding a negligible value not affecting a prediction efficiency to a predicted value. CONSTITUTION:A scan line memory 10 delays the output of an adder circuit by one scan line, a delay circuit 11 allows to delay a signal by one picture element, and an inversion circuit 12 inverts a signal value. An adder circuit 13 adds said signal to generate a predicted value. A decision circuit 21 compares two signal values delayed by one scan line, decides which is larger, a right or left picture element on a reference scan line, controls a negligible value generator circuit 22 according to the result, and generates a positive or negative meager value. An adder circuit 23 adds said value to the estimated value, and encodes the added value as a predicted value. Since the magnitude relation between two picture elements added with arrows varies in transmission and reception, the influence of the mistaken transmission in a predicted picture element from the two picture elements is attenuated.
