Abstract: PROBLEM TO BE SOLVED: To provide a house where the input/output of the indoor and outdoor heat is minimized, the heating/cooling efficiency and the durability are improved, and the barmful compounds that adversely affect the human health are detected to quickly give a warning to the dwellers against a high-airtight structure of the house. SOLUTION: The adiabatic airtight layers are added to the outer wall and also the roof to prevent the input/output of indoor and outdoor heat of a house A, and a heat exchanger C is prepared in an attic space 1 or a space 3 under the floor. Thus, the indoor and outdoor air of the house are inputted and outputted via the exchanger C to attain ventilation for the house with no deterioration of the energy efficiency and also to prevent dew condensation. As a result, the house durability is improved. At the same time, a sensor is placed at least at a part in the house to detect the hazardous chemical materials contained in the air together with a warning device which produces a warning based on the signal received from the sensor.  If a hazardous chemical material exceeds a fixed level, a warning is quickly given to the dwellers of the house to urge them to perform ventilation and also to show a necessary level of ventilation. Thus, it's possible to consider the health of dwellers of the house while saving the house energy.

Inventor: HENDA YOSHIMITSU
IPC: F02D41/00
Filed: 1986-09-16
Abstract: PURPOSE:To prevent the reduction of the fuel injection rate by driving a lamination type piezoactuator in the both injection timing of main injection and subinjection. CONSTITUTION:When a selecting switch 42 is ON in a drive control circuit 30, the pulse outputted from a timing pulse generator 34, accompanied with the revolution of a timing pulse generator 32, is supplied into a wave-form shaping circuit 36 and shaped to a rectangular form, and then supplied into two systems of delaying circuits 38A and 38B. The auxiliary injection control pulse generated in the delay circuit 38A and the main injection control pulse generated in the delaying circuit 38B are synthesized in a drive pulse synthesizing circuit 40, and supplied into a driving circuit 28. Since a piezostack 22 performs extension and contraction operation two times accroding to the drive pulses, the reduction of the fuel injection rate accompanied with increase of the useless volume which is generated because of a piezoactuator 16 can be prevented. Further, when auxiliary injection control is not performed, the selecting switch 42 is turned-OFF.
