Title: Freezer
Inventor: FUJIMOTO SHINJI
IPC: F25B1/00
Filed: 1984-05-07
Abstract: PURPOSE:To enable a lubricating oil to be normally set to a given temperature by the cooling effect of a lubricating oil when the lubricating oil is at a high temperature and by the insulating effect of an insulating material when it is at a low temperature, by a method wherein the electromagnetic valve of a heat pipe mounted to the bottom of a compressor is controlled by a thermostat. CONSTITUTION:When a compressor 1 is operated and the temperature of a lubrication oil 2 is increased to higher than a given temperature by the insulating effect of an insulating material 3, with a thermostat device, not shown, operated, an electromagnetic valve 5 is brought into a releasing state, a heating evaporating part 4A of a heat pipe 4 is communicated with a radiation condensing part 4B, and the temperature of the compressor 1 is lowered by the cooling effect of the heat pipe 4. When the temperature of the lubricating oil 2 is lowered to a given temperature, the electromagnetic valve 5 is brought to a closing state with the aid of the thermostat device, the heat pipe 4 is brought to an inoperative state, and the temperature of the compressor 1 and the lubricating oil 2 is raised again by the insulating effect of the lubricating material 3. Repetition of such operation enables the lubricating oil 2 to be normally held at a given temperature, and this permits viscosity to be held at a low value and allows reduction of the input of the compressor.

Title: Data compression decoding system
Inventor: HAYASHI TAKAAKI
IPC: H03M7/48
Filed: 1994-04-28
Abstract: PURPOSE:To compress image data with high correlation in an excellent way without decreasing the processing speed by combining a run pack coding section with a universal coding section independently of statistic property of an image. CONSTITUTION:When a white or black level picture element appears in input image data D, a white/black run counter section 101 counts the length when runs of white or black level picture elements are consecutive, and a comparator section 102 receives the count N and compares the count N with a predetermined threshold level. Then data are coded by either of a universal coding section 103 and a run pack coding section 104 selected by a control code U/R. When the control code is U, the universal coding section 103 is selected and when the control code is R, the run pack coding section 104 is selected, and the data are coded based on each input value. Thus, an image having long consecutive runs such as a text or an image changing in details such as a dither image is compressed in an excellent way with simple configuration.
