Title: Central cleaner
Inventor: NAKATANI TADASHI
IPC: A47L5/38
Filed: 1993-08-24
Abstract: PURPOSE:To reduce the number of wirings from a vacuum body to receptacles so as to eliminate the polarity in order to enhance the workability by determining the front half and rear half of a half wave having an a.c. power source phase and superposed in a pair of electric wires. CONSTITUTION:As the input voltage of a portable hose communication control part is increased by manipulating a slide volume, the signal transmission frequency of an a.c. half wave in the front half period becomes heigh. The higher the frequency of a received signal is, the more is the power to a body side communication control part 11 fed to a fan motor 10 so as to increase the suction force. Meanwhile, the body side communication control part 11 transmits a high-frequency signal in association with a signal from a dustfull detecting part 15 so as to superpose the signal in a pair of electric wires 9 during a period when a body side a.c. phase determining part 16 indicates the rear haif of the a.c. half wave. When a portable hose a.c. phase determining part delivers a signal indicating the later half of the a.c. half wave, the signal is received so as to turn on a lamp in a display part so as to inform a dust-full condition. Further, a switch in a control part 5 is closed, an a.c. power source feed part 13 in the body 1 delivers a power to a power nozzle motor through the pair of electrical wires 9 and connection terminals in receptacles 2a, 2b, which is therefore rotated.

Title: Binary system
Inventor: NAKAMURA SEIKICHI
IPC: H04N1/403
Filed: 1983-11-07
Abstract: PURPOSE:To make a picture signal into binary properly when the picture signal abruptly changes and also when it changes slowly by controlling a slice level automatically. CONSTITUTION:For a picture signal having a rapid transition, a picture is detected according to a difference signal between a picture signal A and a signal B delayed the picture signal. For a picture signal having a slow transition, a picture is detected in such a way that the picture signal is compared with a voltage having the prescribed potential difference from the maximum or the minimum of the picture signal made into binary immediately before the comparison. By combining the comparison result with the detection result from said difference signal one by one, logical sums are taken in OR gates OR1 and OR2. One outout of the OR and the other output of them are inputted to an FF11 as a set signal and a reset signal, respectively. An output of the FF11 is made binary. Thus, when a picture signal changes abruptly and also when it changes slowly, it can be properly made into binary.

SOLUTION: Selection periods are made into 6τ of 3 times the min. period 2τ of the respective stages of the writing of the state on one selection line by the driving waveforms which divide the writing of the state on one selection line to a part A to be reset to the dark state of the first stage, a part B to simultaneously execute the half bright state writing of the second stage and the bright state resetting of the third stage and a part C corresponding to the writing of the half dark state of the fourth stage. Further, the selection period is made into 4τ if the resetting of the first stage is executed simultaneously in the scanning line i+1 to be selected next during the second, third and fourth stage are executed in the scanning line i.  The impression of the pulses for writing in order to form the desired light transmission state among n kinds of the light transmission state densities varying from each other with every intersected electrode is possible and, therefore, the assigning of 2<n> kinds of intensity levels by shortening the selection period is possible.
