Title: Motion detecting device
Inventor: AKIMOTO TAIZOU
IPC: H04N7/18
Filed: 1978-04-06
Abstract: PURPOSE: To eliminate the misjudgement at the low-luminance region for the device which detects the action at each point of the image based on the luminance difference of the video signal by amplifying large the signal of the low-luminance region and narrowing the width of the threshold.  
     CONSTITUTION: The signal at each point of one frame of the video signal which is supplied via A/D converter 10 and arithmetic circuit 11 is memorized in frame memory circuit 12. Then the signal of each point of the memorized preceding frame is read out via write/read control circuit 14 to be compared with the signal of each point of the frame this time at absolute value arithmetic circuit 19. And the motion of the image is detected at each point based on the difference of the luminance. In such motion detecting device, black extension nonlinear converting means 17 and 18 are provided to increase the low-luminance regions for the signals of both the preceding and present times. These means 17 and 18 are constituted as the logarithm conversion table in which the output signal is preset to the input signal, and thus the threshold width can be reduced at circuit 19.

Abstract: PROBLEM TO BE SOLVED: To prevent conducting short-circuit and eliminate static electricity by supporting a tip member formed of ceramics of specified volume specific resistance and forming a supporting member performing a clamping operation by a material having specified volume specific resistance. SOLUTION: A holding tool is made b forming a pair of tip members 1 out of ceramics of volume specific resistance 10<3> to 10<9> Ω.cm, joining the rear end of this tip member 1 to a supporting member 2 of volume specific resistance 10<11> to 10<16> Ω.cm with an adhesive, etc., and supporting the rear end of this supporting member 2 by an elastic engaging body 3. By performing a clamping operation by hand, the elastic engaging body 3 elastically deforms and an object is held between the tip members 1, 1 at the tip. When volume specific resistance of the tip member 1 is less than 10<3> Ω.cm, little effect in prevention of short- circuit is produced. When volume specific resistance exceeds 10<9> Ω.cm, the efficiency of removing static electricity is decreased.

Abstract: PURPOSE:To make an electric vacuum cleaner move according to the intention of a person who is cleaning at the time of normal usage under avoiding obstacles easily by a method wherein sensors which protrude from the main body of an electric vacuum cleaner are provided at front parts on the side surfaces of the main body, and front and rear wheels are made to face the opposite direction to an obstacle when this sensor comes into contact with and senses the obstacle. CONSTITUTION:When an obstacle is located left forward of the main body while the title electric vacuum cleaner is in use, a sensing unit 6 on the left side of the main body comes into contact with the obstacle, and a sensor 3 turns backward of the main body with a left side sensor shaft 4 as its pivot, and then, a connecting rod 21 is pressed backward of the main body by a groove 19 with which the connecting rod 21 is engaged. By this motion, a rear wheel holding part 10 on the left side turns forward of the main body with the shaft 9 on the left side as its pivot. Since a connecting part 15 moves in the main body-lateral direction by turning of a connecting rod 13 at the same time, the connecting part 15 presses a caster 22 which normally does not receive regulation, and turns the caster 22 to direction-regulate. Thus, the obstacle is avoided.

Title: Magnetic recording method
Inventor: TOMITA MASAO
IPC: G11B5/027
Filed: 1987-02-25
Abstract: PURPOSE:To decrease the occurrence of cross modulation component between multiple signals by multiplexing plural different kinds of signals including frequency-modulated signals in terms of frequency and impressing a high frequency bias so as to supply a recording signal to a magnetic recording head. CONSTITUTION:A color video signal is separated to a luminance signal and a carriage chrominance signal by a low pass filter 5 and a band-pass filter 8 and FM-modulated luminance signal and the carriage chrominance signal converted in terms of low pass are inputted in a synthesizing unit 11 with respectively occupying separate bands. Then both signals are multiplexed in terms of frequency and amplified in a recording amplifier 12 to be inputted in a synthesizing unit 13. Meanwhile, a signal which gives a high frequency bias magnetic field generates the frequency equal to several fold frequency of the maximum frequency of the recording signal in a bias oscillator 15, which is amplified in an amplifier 14 and inputted in the synthesizing unit 13. The frequency multiplexed signal superposed on the high frequency bias is given to a rotary head 16 and recorded in a video track on a magnetic tape 17. Thus, cross modulation more between both signals can be remarkably decreased since the input/ output relation of an electromagnetic conversion system becomes nearly linear.
