Inventor: PREMJI GULAM
IPC: B60N2/20
Filed: 1993-02-10
Abstract: Cette invention concerne un mécanisme de verrouillage pour dossier de siège d'automobile inclinable vers l'avant. Le mécanisme de verrouillage sert à empêcher le dossier de pivoter vers l'avant lorsqu'il est en position relativement verticale, en bloquant les deux éléments de la charnière d'articulation du dossier. Il se compose d'une première et d'une seconde butées solidaires d'un premier élément de la charnière, d'un premier et d'un second butoirs solidaires du deuxième élément de la charnière d'articulation et d'un élément de verrouillage articulé au premier élément de la charnière d'articulation et manoeuvrable entre une position de verrouillage et une position de déverrouillage. Lorsque l'élément de verrouillage manoeuvrable est en position de verrouillage, les premiers butoir et butée sont en contact étroit pour empêcher un mouvement de pivotement relatif intempestif des premier et second éléments de la charnière d'articulation vers l'arrière. De plus, une première surface de contact sur l'élément de verrouillage manoeuvrable et le second butoir sont en contact étroit et l'élément de verrouillage manoeuvrable est intercalé entre la seconde butée et le second butoir pour empêcher le pivotement intempestif des deux éléments de la charnière d'articulation l'un par rapport à l'autre, vers l'avant. Par conséquent, on obtient une perte d'amplitude de mouvement radial quasi nulle entre les premier et second élément de la charnière d'articulation, dans une première orientation angulaire relative.

Title: Picture signal recording device
Inventor: KANDA YUKO
IPC: H04N9/83
Filed: 1993-12-23
Abstract: ABSTRACT OF THE DISCLOSURE    A picture signal recording device for recording color video signals is disclosed.  A color signal detection circuit detects the quantity of motion of chroma signals from an inter-frame difference between  a color  difference signal  from a  chroma recording processing circuit and a signal delayed by one frame from the color difference signal.  A dynamic change smoothing filter circuit smoothes sudden changes in the quantity of motion of the chroma signal.   A luminance signal  motion detection circuit detects the quantity of motion of chroma signals from an inter-field  difference  between  a  luminance  signal  from  a luminance recording processing circuit and a signal delayed by one frame from the luminance signal.  A maximum value detection circuit detects the maximum value of the quantity of motion of the chroma signal and the quantity of motion of the luminance signal. The adaptive processing circuit controls the quantity of transmission of the sub-Nyquist sampled color signal depending on the maximum value.  Thus the sub-sampled color signal sub-sampled responsive to the motion of the picture is transmitted, while motion detection may be made without necessitating a memory exclusively used for motion detection.

Abstract: A pilot operated directional control valve communicates fluid between a hydraulic actuator, a pump and a reservoir.  A lockout valve is connected between each main control valve work port and a corresponding cylinder port, and operates to reduce fluid leakage therefrom.  Each lockout valve includes a pressure responsive poppet valve member which is exposed to fluid pressure in a lockout chamber.  A vent control valve is connected between each lockout valve and a corresponding one of the pilot valves.  Each vent control valve includes a vent check valve which controls fluid venting from the lockout chamber and a vent piston which is biased to urge the vent check valve to a closed position thereby trapping fluid in the lockout chamber.  When both pilot valves are energized, both lockout valves are vented and a float valve moves to a position wherein both cylinder ports are communicated, via the lockout valves and the float valve, with each other and with the reservoir.  The float function is obtained without the requirement of additional solenoids or by compromising the available modulation range of the main control valve.
