Title: Air conditioner
Inventor: IOJI KOUICHI
IPC: F25B1/00
Filed: 1991-10-21
Abstract: PURPOSE:To enable a stable release control and shorten the time it takes for the room temperature to reach a set temperature. CONSTITUTION:An inverter frequency control means 7 normally performs Ts-Ta control based on a command signal from an inside temperature control means 15. However, when room heat exchange temperature Tc exceeds a first set value Tc1, a control changeover means 18 changes over the output of the command signal so that the control means 7 performs a release control based on a command signal from an inside heat exchanger temperature control means 16. And the control means 16 maintains the output of inverter frequency command signal at the time when the inside heat exchange temperature passes the first set value Tcs1 until the inside heat exchange temperature Tc falls from the level of the first set value Tcs1 to the level of a second set value Tcs2.

Title: Method for generating determination tree
Inventor: KAKISAKA YOICHI
IPC: G06F9/44
Filed: 1992-09-16
Abstract: PURPOSE:To provide the method which is reducible in calculation quantity and accurately corrects contradiction between cases even if the contradiction is generated. CONSTITUTION:Attributes which have successive values are divided into a finite number of sections. Namely, when some attributes of cases of a training case set have successive values, areas that the numerals belonging to respective classification classes occupy, are found and intersections of the respective areas or points between the areas are regarded as points dividing the value area into the sections. If a case having contradiction which hinders the generation of the determination tree is generated, the contradictory case is redivided as a training case set only in a section including it, and the attribute values are updated and used to regenerate the determination tree, thereby removing the contradiction of cases which is caused by a deficiency in section division.
