Title: Heat accumulating air conditioner
Inventor: KUROIWA KAZUO
IPC: F24F5/00
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a heat accumulating air conditioner which is capable of cooling/ heating/defrosting/ventilating at a hot or cold sever climate environment by providing two and more expansion valves on a heat accumulating unit and further providing a heat exchanger in the heat accumulating unit, an outdoor unit and an indoor unit respectively. SOLUTION: In a winter cycle, a heating medium is circulated in the arrow 24 direction. When the outside air temperature is high and frost is not deposited on a heat exchanger 27 of an outside unit 4, heart accumulation is carried out. When both heat accumulation and heating are carried out at the same time, an expansion valve 9 is constituted while an expansion valve 6 is opened. When the outside air temperature is low and frost is produced on the heat exchanger 27, heating is carried out with the heat of a latent heat accumulation material 30. At that time, the heating medium is circulated in the arrow 24 direction. The expansion valve 6 is constricted while the expansion valve 9 is opened. In a summer cycle, the heating medium is circulated in the arrow 10 direction.  When both heat accumulation and cooling are carried out at the same time, the expansion valve 9 is constituted while the expansion valve 6 is opened. When only heat accumulation is carried out, the expansion valve 9 is constituted while the expansion valve is opened as well.

Title: Ceramic substrate for igniter
Inventor: HATORI MASAKAZU
IPC: H05K1/03
Filed: 1986-09-12
Abstract: PURPOSE:To obtain a ceramic sintered body possessing characteristics proper to be used as a heat-radiating plate for an igniter and capable of mounting directly an Si chip on its own body by a method werein the product of a heat capacity (C: Joul/ g deg.C) and a thermal conductivity (K: Joul/cm.s. deg.C) and moreover, the value of a thermal expansion coefficient alpha are specified. CONSTITUTION:Out of the characteristics to be required for a ceramic sintered plate, the value of CXK is a parameter which stipulates the good or bad of heat dissipation property of the ceramic substrate. This value shalle be 1.5 Joul<2>/sec.cm<3>.K or more. In case the value is smaller than this value, the amount of heat generated in an Si chip is accumulated without being dispersed rapidly. As a result, such troubles as the disconnection of a circuit begin to frequency occur. It is desirable for the value of the alpha to be approximate to the value of alpha Si as much as possible, but the alpha is set to be 1.5X10<-6>/ deg.C-5.5X10<-6>/ deg.C. The manufacture of ceramics having the alpha smaller than 1.5X10<-6>/ deg.C is industrially impossible as a matter of fact and in the case of ceramics having the alpha larger than 5.5X10<-6>/ deg.C, the difference between the alpha and the alphaof the Si chip to be mounted becomes too large and a peeling phenomenon and so on due to thermal stress are generated. That is, AlN substrates to satisfy all these characteristics have respectively a good heat dissipation property and are proper as a heat-dissipation plate for an igniter.

Filed: 1985-09-30
Abstract: PURPOSE:To obtain a Schmitt circuit having a nearly constant characteristic in a binarization phase with respect to an input signal and with excellent noise immunity by providing an integration circuit integrating an output signal of the 1st Schmitt circuit and changing a reference potential of the 2nd Schmitt circuit as the elapsed time. CONSTITUTION:An output waveform of the 1st Schmitt circuit 21 is inverted as shown in a caption SH1 every time an input signal S1 passes a reference potential Vth1. Further, the reference potential Vth1 of the 1st Schmitt circuit 21 is inverted alternately to a positive/negative level as the output waveform SH1 as shown in the caption Vth1 and an output signal of the integration circuit 26 is a caption SIGMASH1. Since the reference potential Vth2 is biased by an output signal of the integration circuit 26 in the 2nd Schmitt circuit 22, the output waveform is inverted when it has a lead phase THETA1 with respect to the peak of the input signal S1. Thus, the binarization phase with respect to the input signal is made nearly constant independently of the frequency of the input signal to improve noise immunity.
