IPC: G05B13/02
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To improve learning accuracy of output value of a sensor, etc., by sampling signals A and B alternately at the same cycle and at shifted timing, and learning the output value of the signal A just before the out put value of the signal B is inverted. SOLUTION: A detection signal A from a throttle sensor 23 corresponding to an opening of a throttle valve 22 and a detection signal B of an idle switch 23a which is turned on in the idle opening area of the valve 22 of a full-switch 23b which is turned on in the full-open area are sampled at the same cycle and shifted timing, and one signal is sampled at the middle of the sampling cycle of the other, respectively. Then, when the output value of the signal B is inverted, the output value of the signal A sampled just before is learned as an output value of the signal A at the time when the output value of the signal B is reversed. Thus, the maximum time difference between the actual reversing points of the signal B and the output value learning points of the signal A can be reduced to a half of the sampling cycle.

Title: Heat-pump hot-water supply machine
Inventor: TAGASHIRA MINORU
IPC: F24H1/00
Filed: 1987-11-24
Abstract: PURPOSE: To ensure high temperature boiling while suppressing radiation loss by utilizing waste heat from a first heat pump cycle effectively as the heat source for a second heat pump cycle thereby eliminating a pump for heating hot supply water. CONSTITUTION: In a second heat pump cycle 33, gas delivered from a compressor 38 flows through a delivery tube into a second double tube heat exchanger 29 for condensation where heat exchange takes place between hot supply water and natural convection. High temperature high pressure refrigerant gas is condensed and reduced in pressure by an expansion valve 39 and then evaporated in a supercooling heat exchanger 35 by robbing sensible heat from a first heat pump cycle 28. It is then heat exchanged in an evaporator 40 with the atmospheric heat and sucked into the compressor 38. When the upper part of a hot water storage tank 20 is boiled at high temperature in the first heat pump cycle 28, waste heat at liquid refrigerant after ending heat exchange with hot supply water is employed as the heat source for the second heat pump cycle 33.  Since low pressure of the second heat pump cycle 33 can be raised, high performance can be attained.
