Title: Air conditioner
Inventor: TOMIOKA SATOSHI
IPC: F24F11/02
Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain an air conditioner (multi-type air conditioner) in which the heat exchanger of a foot type indoor unit is protected against dew formation by detecting leakage of valve due to reverse coupling of refrigerant piping or failure of an expansion valve. SOLUTION: At the time of cooling operation of the air conditioner, variation (Tex1, Tex2) in the heat exchanging temperature of a foot type indoor unit is detected upon starting a compressor (steps ST1 through ST4). When the variation (Tex1, Tex2) exceeds 5 deg.C (step ST5), the control advances from step ST6 to ST7 if the indoor fan of the foot type indoor unit is not rotating and a decision is made that a valve is leaking due to reverse coupling of refrigerant piping or failure of an expansion valve and then an outdoor fan is stopped. Difference between the room temperature and the heat exchanging temperature is detected every predetermined time at the foot type indoor unit 2 and only when the temperature difference is 5 deg.C or higher two times continuously, a protection bit of L level is transmitted to the outdoor unit.  When the protection bit has an L level, the control advances from step ST6 to ST7 even if the indoor fan is rotating and operation of the compressor and the outdoor fan are interrupted.

Title: Picture processing method and picture processor
Inventor: MIMA TAKESHI
IPC: G03G15/01
Filed: 2000-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a picture processing method and a picture processor, which can correct a gradation skip while the quality of a whole picture is maintained. SOLUTION: In LUT, it is set whether random data is added or not at every area in color picture data displayed by address bit '1' and '2' (data bit 7). Then, ON/OFF of random number addition can be switched in accordance with a character area or an area out of the character area (address bit '0'). Thus, random number data is added only in the area where the correction of the gradation skip is required and the remaining area can maintain an original picture.

Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a lithographic form plate packaging material which can be made up at a low cost and has a high separability against a non-image- forming surface of a lithographic form plate, and also to provide a packaging structure using such packaging material. SOLUTION: A laminated paper 14 has a Bekk smoothness in 35 seconds or more and not exceeding 55 seconds at its non-contacting surface which does not contact with a coated surface of the lithographic form plate 10. The non- contacting surface contacts with the non-image-forming surface of the adjoining lithographic form plate 10 in a piled-up layer 12. However, because of its high separability against the non-image-forming surface, the interleaving paper 14 does not stick fast to the non-image-forming surface of the lithographic form plate 10, and the lithographic form plate 10 is not supplied to an auto-processor or the like together with the interleaving paper 14, preventing stoppage of plate feeding operation. With low-cost materials selected for forming the laminated paper 14, the packaging structure can be made up at a low cost.

Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner for an automobile capable of excellently controlling air conditioning even when outside air temperature is high. SOLUTION: The first judging values Tfb1 and Tbf1 suitable for normal outside air temperature at a preset value T1 or below, and the second judging values Tfb2 and Tbf2 suitable for high outside air temperature exceeding the preset value T1 are stored in nonvolatile memory. The outside air temperature Ta is watched by the outside air temperature sensor 26, when the outside air temperature Ta is at the preset value T1 or below, a mode is switched to a foot mode or a bilevel mode with the first judging values Tfb1 and Tbf1. When the outside air temperature Ta exceeds the preset value T1, the mode is switched to the foot mode or the bilevel mode with the second judging values Tfb2 and Tbf2 which have smaller values than that.  Thereby, when the outside air temperature is high, the foot mode is preferentially selected to the bilevel mode, and comfortable air conditioning appropriate to the outside environment is achieved.
