Title: Air conditioner
Inventor: MATSUBARA MITSUNORI
IPC: F25B13/00
Filed: 1987-12-14
Abstract: PURPOSE: To perform defrost operation while preventing overload through a convenient and inexpensive method by providing a five-way valve coupled with the delivery pipe of a compressor, a cooling/heating exchange valve and a bypass valve for opening/ closing a bypass pipe coupled closer to the suction pipe side than the five-way valve. CONSTITUTION: A cooling exchange valve 46 is turned to the the position of heating operation at the time of heating operation and a motor expansion valve 39 has a set opening. When an outdoor heat exchanger 33 begins to frost during heating operation and the coil temperature drops below 0 deg.C, a bypass valve 47 opens to pass delivery gas from a deliver pipe 35 through a bypass pipe 34 into a suction pipe 36. On the other hand, the motor expansion valve 39 opens fully to increase circulation quantity of refrigerant and high temperature high pressure gas not condensed through an indoor heat exchanger 40 flows into the outdoor heat exchanger 33 thus defrosting it.  When a CT interposed between the compressor 31 and the electric instrument section detects a current higher than a specified level during cooling operation, the valve 47 opens to bypass delivery gas to the suction pipe 36 thus lowering the high pressure and the current. Defrost and overload preventing performance is thereby enhanced resulting in a compact product.

Title: Output element for artificial neural unit
Inventor: SAKAGAMI SHIGEO
IPC: G06F15/18
Filed: 1988-12-15
Abstract: PURPOSE:To reduce the circuit scale and to increase the working speed for an output element by expressing the input/output characteristics in a polynominal which can be continuously differentiated. CONSTITUTION:An output element circuit consists of the double input multipliers 2 and 3, a triple input multiplier 4, an adder 5, and a comparison/selection circuit 6. Then the input/output characteristics are expressed in a polynominal which can be continuously differentiated. For instance, an output signal (y) is expressed in the following equation to an input signal (x) for an output element 1. That is, y=0.5+0.075x-0.00025x<3>, where (-10<=x<=10), y=0(x<=-10), and y=1(x>=10) are satisfied. In other words, the multipliers 2, 3, 4 and the adder 5 output 0.075*x, x<2>, -0.00025*x<3>, and 0.5+0.075x-0.00025x<3> respectively to the signal (x). The circuit 6 compares the signal (x) with 10 and -10 respectively and outputs 0.5+0.075x-0.00025x<3> with (-10<=x<=10), 0 with (x<=-10), and 1 with (x>=10) respectively. Thus the circuit scale is reduced and the processing speed is increased for an output element of an artificial neural unit.
