IPC: H04N7/01
Filed: 1986-10-22
Abstract: PURPOSE:To prevent a block boundary from being displayed prominently, and the delay of display from being generated, by repeating a transmitted frame or field. CONSTITUTION:A bit of information regarding a ratio Pf for all of the encoded frames from an entropy decoding circuit 104 is sent to an interpolating method selection circuit 118, and the interpolating method selection circuit 116 compares the ratio Pf with a prescribed threshold value Th. The interpolating method selection circuit 118, when the ratio Pf being less than the threshold value Th, outputs indication to select a picture element value reproduced by a frame repeating interpolation circuit 108, meanwhile, when the ratio Pf exceeds the threshold value Th, it outputs the indication to select the picture element value reproduced by an interpolation circuit 109 using a moving quantity. Next, an NTSC synthesizing circuit 114 performs the frame synthesis of a selected frame and an encoded frame by a switch 112, and a D/A converter 116 converts it to a TV signal.

Abstract: PROBLEM TO BE SOLVED: To enable a use to make espresso coffee by utilizing a dripper of a triangular paper filter system. SOLUTION: Water is put into a water tank 2 and the tank is hermetically sealed. The dripper 6 of the paper filter type, into which coffee powder is put, is mounted at a dripper mounting part 4 of a device body 1. The water in the water tank is heated and boiled by a heater 13.

Abstract: PURPOSE:To obtain a satisfactory color display without adjusting the thickness of a liquid crystal layer by placing a second liquid crystal cell having no display electrode. CONSTITUTION:A first liquid crystal cell 10 for displaying an image is brought to twist array to a state that an inclination in the pre-tilt direction on one substrate surface and an inclination in the pre-tilt direction on the other substrate surface are reverse to each other, and also, the pre-tilt angle becomes smaller as it separates from the substrate surface, when a liquid crystal molecule array state between both its substrates is expanded along its twist direction and looked at. Therefore, a threshold characteristic becomes steep without lowering a response speed, and even against multiplex driving by a high duty, a satisfactory contrast and a wide visual field angle can be obtained. Also, by placing a second liquid crystal cell 20 having no display electrode, coloring of a display in a first liquid crystal cell 10 is negated. In such a way, by equalizing roughly transmittivity of light of all wavelength areas, coloring of a display screen can be eliminated.
