Title: Air conditioner
Inventor: MATSUMOTO KIYOSHI
IPC: F25B13/00
Filed: 1995-01-27
Abstract: PURPOSE: To achieve the space heating through the refrigerant heating by making a correct judgement of the leakage of the refrigerant, and to safely stop an air conditioner in an emergency. CONSTITUTION: When space heating is achieved while the refrigerant is heated by a refrigerant heating equipment 5, the temperature of an indoor heat exchanger 3 is detected by an indoor heat exchanging thermistor 10, and when the detected temperature is below a prescribed value, a judgement is made that the refrigerant is leaked. After the refrigerant collecting operation is achieved for the prescribed period of time, the operation is returned to the space heating mode. On the other hand, when the detected temperature exceeds the prescribed value, the heating operation is continued until the heating is completed.  A means to avoid the effect of the indoor temperature for the temperature of the indoor heat exchanger 3 is proposed where the temperature difference between the inlet and the outlet of the indoor heat exchanger 3 is detected, and the refrigerant collecting operation is achieved by making a judgement that there is the leakage of the refrigerant when the temperature difference exceeds the prescribed value. A means to wait until the temperature of the indoor heat exchanger 3 is stabilized, and a means to prevent the mis-judgement depending on the preset air volume of an indoor fan, the combustion amount of a refrigerant heating equipment 5, etc., are included.

Filed: 1983-01-28
Abstract: PURPOSE:To shorten the delay time in the start of control on starting an engine by judging that the first signal contains standard signal added with position signal or not when the engine strats and controlling each start of ignition control and fuel injection control. CONSTITUTION:It is judged in Steps 2, 3, and 4 that the first signal contains a standard signal added with position signal or not when engine starts. When the first signal is position signal only, only fuel injection control is started immediately. When the first signal contains both standard signal and position signal, ignition control and fuel-injection control are started immediately. Thus, the delay time in start of control on starting engine can be sufficiently shortened.

Abstract: PURPOSE:To provide an effective prevention of the dust dispersion by a method wherein some industrial waste mateials etc. are filled or charged up to the top end of the upper diverged section in the combustion gas flowing up passage and kept as they are. CONSTITUTION:Dried sludge such as waste materials etc. is uniformly supplied on the top surface of the hot furnace heater 1 from sludge feeding downstream passage 6 and then charged substantially up to an upper end of the upper diverging section 5a in the combustion waste gas flowing up passage 5. A volume of supplying a combustion oxygen containing gas to be fed to the combustion part 2 is set low in advance, combustioned and melted under a lack of oxygen, and when a volume of generating combustion waste gas is decreased, a blowing speed of the combustion waste gas up to the upper surface of the combustion layer containing some waste matrials is decreased and thereby a dispersion of the dust is restricted. When a sectional diameter of th flowing up passage 5 is increased and a height of the pasage is increased, the flowing up speed of the waste gas is decreased to form a rectified flow and to improve a performance of dust separation caused by a natural dropping of the dust.

Filed: 1992-01-28
Abstract: PURPOSE:To improve an output efficiency of an output system by adding a reset current of a transformer through a diode as a power source of an output system having no exclusive use tap. CONSTITUTION:A reset current of an end of a secondary winding of a transformer T connected to a -15V DC voltage output system is added to a second capacitor C2 for constituting a +5V DC voltage output system through a third diode D3, and a reset current of an end of the secondary winding of the transformer T connected to a +15V DC voltage output system is added to a fourth capacitor C4 for constituting a -5V DC voltage output system through a fifth diode D5. Thus, at the time of resetting, the input voltage of the diode D3 is clipped to the power source voltage of the +5V DC voltage output system. Here, when ratios of the number of turns of the secondary windings are equal, a voltage having reverse polarity to that of the input voltage of the diode D3 is induced at the input side of the diode D5 to obtain a voltage necessary to output a -5V DC voltage.
