Patent JP-H07190566-A (JP)
Title: Accumulator
Inventor: MORIMOTO OSAMU
IPC: F25B43/00
Filed: 1993-12-27
Abstract: PURPOSE:To selectively return only refrigerating machine oil to a compressor irrespective of an amount of refrigerant liquid in an accumulator by providing means for sensing a liquid level, and conveying means for returning oil from the sensed level to the compressor. CONSTITUTION:A float 10 vertically moves to match a position of a liquid level in an accumulator. A flexible tube 11 is connected at its one end to the float 10, and at the other to a return tube 9 at a bottom of an accumulator body vessel 6. A return oil hole 12 is opened near a connecting part of the float 10 to the tube 11. The float 10 floats on liquid surface in the vessel 6. Since refrigerating machine oil has smaller density than refrigerant liquid, the oil exists near the liquid surface, is sucked from the hole 12 into the tube 11, and guided to an outlet tube 8 through the return tube. The oil is returned together with refrigerant gas to a compressor. Thus, the oil retained in the vicinity of the surface can be effectively returned by a simple method.

Title: Moving compensation prediction inter-frame coder
Inventor: MATSUKA TETSUYUKI
IPC: H04N19/107
Filed: 1990-11-29
Abstract: PURPOSE:To improve the picture quality of a reproduced picture by applying numeral conversion taking an orthogonal transformation coefficient as a quantization step size so as to prevent that an orthogonal transformation coefficient having a size of some degree or larger after quantization becomes '0'. CONSTITUTION:A quantization section 23 uses a quantization step size 21 to quantize an orthogonal transformation coefficient 22 subject to numeral conversion to calculate an orthogonal transformation quantization coefficient 24. When the orthogonal transformation coefficient and the quantization step size are equal, the quantization section 23 calculates '1' or '-' as an orthogonal transformation quantization coefficient 24. A prediction error coding section 33 codes a coding system selection signal 10, a quantization step size 21 and an orthogonal transformation quantization coefficient 24 to calculate a prediction code 34. At the quantization of the orthogonal transformation coefficient, since the orthogonal transformation coefficient is smaller slightly than the quantization step size, the orthogonal transformation coefficient having been quantized to a numeral '0' is left after the quantization, then the picture quality of the reproduced picture is improved.
