Abstract: A programmable logic circuit includes a memory sector and other logic elements which are laid peripherally, wherein the memory sector is prestored with possible input data and output data which are derived by fuzzy reasoning. In application, observed data on an objective entity outside is first treated by a logic element to convert the data to digital form and then input as an address in the memory sector wherein the input observed data is converted by fuzzy logic to an operative data, which is sent to downstream to subsequent circuit elements to control a device. The illustrated embodiment is for an air-conditioning system wherein introduction of a memory sector having fuzzy logic based data will prevent erroneous actions in the downstrem devices which are caused by erroneously input data, in the process of processing data by a conventional programmable logic circuit.

Abstract: The present invention relates to a method of producing a mold material used for obtaining a mold for casting metals such as Zn, Al and the like or molding resins. In the method, the short fibers having an aspect ratio of 30 to 300 and obtained by cutting ferritic stainless steel long fibers having a width of 100 .mu.m or less, ferritic stainless steel powder and at least one of Cu powder and Cu alloy powder are used as raw materials. The raw materials are blended to obtain a material mixture which is then compressed under pressure in a Cold Isostatic Press process. The thus obtained compressed product is sintered in a vacuum atmosphere. The sintered material is held in an atmosphere of nitrogen gas or decomposed ammonia gas so that 0.3 to 1.2 wt % of nitrogen is added to the stainless steel in the sintered material. The thus obtained mold material has a hardness of HMV 250 to 500.

Abstract: This invention relates to a method of annoucing a low level of the remaining liquid in a dropper. According to the present invention, two electrodes are attached to the outer surface of a dropper, and a pulse of a stable level is applied to one of these electrodes. The remaining quantity of the liquid in the dropper can be detected automatically with ease by utilizing the variations of the electrostatic capacity occurring between these two electrodes. An annunciator is activated when it receives a signal representative of a low level of the liquid in the dropper, to inform a nurse of the necessity of replacing the dropper.
