Abstract: PURPOSE: To improve storage performance of perishable foods or the like, by arranging air jetting holes above a cooling chamber so as to jet more of cool air on the side of a front part as compared with the rear part side of the cooling chamber. CONSTITUTION: Air jetting ports 16 and 16 of cool air are arranged horizontally at positions above a cooling chamber 20 on both, side walls 12 and 12 of a refrigerator 10 and an array interval is reduced on the front side of the cooling chamber 20 to make an area of an opening, so that more of the cool air flows through a part 15 into the upper inner circumference of the cooling chamber 20 from the air jetting ports 16 and 16 and moves to the rear side from the front side thereof. In this process, the cool air undergoes a heat exchange with an object to be cooled in the cooling chamber 20 reaching a high temperature, arrives at the rear part to turn it to a temperature rising air flow, moves again to the front side and rises up to an upper stage cooling chamber 20' passing through an air port 24'. Thus, almost an even temperature cold region is developed as a whole to eliminate a difference in cooling effect of an object to be cooled, thereby improving storage performance of perishable foods or the like.

Abstract: PURPOSE:To constantly obtain a maximum output efficiency by constituting the system in such a manner that the data on both fuel consumption quantity and ignition timing, which is stored in the random access memory, is corrected and updated every time an engine is operated and exercising the control, based on this updated data. CONSTITUTION:When the number of revolutions of an engine 10 reaches a prefixed value, initial values of both fuel injection quantity and ignition timing, which correspond to this number of revolutions, are set first, and next the torque of a propeller shaft (output shaft) 21 is measured by means of rotary torque encoders (torque detecting means) 5 and 6, gradually changing the above-mentioned injection quantity and ignition timing. This torque value varies, according to an air fuel ratio and ignition timing, while the engine output is proportional to the product of the torque value and the number of revolutions. In this connection, both fuel injection quantity and ignition timing with which the torque value of the shaft 21 becomes maximum are obtained from the above measurement data and stored in the form of a map in the random access memory. By reading this map, both fuel injection quantity and ignition timing can be controlled in correspondence to the number of revolutions, so that the engine output becomes maximum.

Next, the output of the switching device 13 and a wobbling signal are subjected to frequency comparison by a frequency error detector 6 and a frequency error is outputted. Simultaneously, the output of the switching device 13 and the phase of an RF signal are compared by a phase error detector 7 and a phase error is outputted. A switching device 8 selects the output of the frequency error detector 6 in a prescribed period in the initial period of the lead-in. When the frequency lead-in period ends, the switching device 8 selects the output of the phase error detector 7.  The output of a VCO 10 is used as 1/m (for example, m=2) in the case of seeking from the outermost periphery to the innermost periphery.
