Abstract: PROBLEM TO BE SOLVED: To provide a refrigerating system for enhancing safety drivability and an economy by reducing in size a condenser and raising a cooling performance and a coefficient of performance of an evaporator. SOLUTION: A high pressure liquid refrigerant condensed by a condenser 2 is branched. The refrigerant of a much branched amount side is sent to a high pressure side refrigerant passage 7 of an intermediate cooler 6. Meanwhile, the refrigerant of a little branched amount side is sent to a high temperature side pressure reducing means 5, pressure reduced, expanded to a low temperature and low pressure liquid refrigerant. The liquid refrigerant is sent to a low pressure side refrigerant passage 8 of the cooler 6. The liquid refrigerant heat exchanges with a high pressure liquid refrigerant flowing to the passage 7. Thus, the high pressure liquid refrigerant of the passage 7 is cooled to a lower temperature. Meanwhile, the low temperature and low pressure liquid refrigerant of the passage 8 is evaporated. The low temperature and low pressure liquid refrigerant fed via the passage 7 is sent to a low temperature side pressure reducing means 3. This liquid refrigerant is pressure reduced and expanded. Then, this liquid refrigerant is sent to the evaporator 4, evaporated and vaporized. The evaporated and vaporized low pressure condensible gas refrigerant and the low pressure condensible gas refrigerant evaporated and vaporized via the passage 8 of the cooler 6 are combined, and then returned to a compressor 1.

Title: Quantization method and recording system using the quantization method
Inventor: SUWA TETSUYA
IPC: H04N1/40
Filed: 2000-04-17
Abstract: PROBLEM TO BE SOLVED: To improve the compression rate of an image without degrading the quality by using a discrimination matrix with a periodicity that is generated by adding a prescribed condition to a matrix of the blue noise method to quantize the image. SOLUTION: In the case of generating a matrix with a size of 128×128 to express 8-bit 256-gradation in a binary method, in order to decide an upper stage component 128×255, 64 sets of '0s' satisfying a prescribed condition of gray levels are selected and converted into '1s' and Fourier transform, filtering, inverse Fourier transform, rearrangement of errors, exchange between '1' and '0', and calculation of total sum of errors are repeated until the total sum of the errors is minimized. Objects of exchange between '1' and '0' in the error rearrangement are limited to dot profiles whose level has been '0' before the gray level is increased so as to always reserve an initial dot profile with periodicity thereby preventing the periodicity from being lost due to a change in the gray level. Lower stage components 0-126 are processed similarly to above and the matrix is completed.
