Title: Air conditioner
Inventor: TAKAYANAGI KATSUAKI
IPC: F24F11/02
Filed: 1992-05-11
Abstract: PURPOSE:To enhance an efficiency of a room heating operation by eliminating an erroneous operation of defrosting of an outdoor unit of an air conditioner. CONSTITUTION:The air conditioner comprises a base 1, a compressor 2, a heat exchanger 3, a blower 4 for air-cooling the exchanger 3, etc., a support 5 for supporting a motor of the blower 4, and a PTC element 6 attached to the support 5. The air flows in a direction of arrows. When room heating is conducted, frost is adhered to the exchanger 3, and a flow of the air is deteriorated, and hence its heat exchanging efficiency is reduced. The element 6 is raised at its temperature. Since a current flowing to the element 6 is decreased inversely proportionally to a temperature, a frost adhering state of the exchanger 3 can be indirectly detected if the current of the element 6 is detected by using current detecting means. The detected current is A/D-converted, and input to a microcomputer. The microcomputer stars defrosting when the detected current becomes a predetermined level or less.

Abstract: PROBLEM TO BE SOLVED: To cut a wire protector accurately, surely, and perpendicularly by forming a moving blade with a cutting section and a fitting section, and forming a clearance groove matched with the shape of the cutting section on a bearer in a cutting tool of the wire protector protecting a wire. SOLUTION: When a wire protector is set on a bearer B and a moving handle 11 is gripped by a hand, a ratchet pawl 12 fitted to the moving handle 11 is moved, and ratchet teeth are rotated. A cutting section 1 is moved downward and bites into the wire protector while a fitting shaft 9 serves as a fulcrum. When the force of the hand is loosened, the ratchet pawl 12 is moved to the left astride the ratchet teeth, and the moving handle 11 is widened downward by the movement of the ratchet pawl 12. When the moving handle 11 is again gripped, the ratchet pawl 12 rotates the ratchet teeth, and the cutting section 1 is further lowered. When these actions are repeated, the wire protector is cut off.

Title: Color image contour extracting method applying fuzzy inference
Inventor: MATSUSHITA ATSUSHI
IPC: G06T7/60
Filed: 1993-05-19
Abstract: PURPOSE:To adapt a systematic inference to each method by means of a fuzzy inference and also to facilitate the control of a parameter. CONSTITUTION:A membership function is controlled in accordance with the characteristic of an image and then six rules are applied to the lightness value of each pixel of the image. Then a rule that can acquire the maximum value by a fuzzy arithmetic operation is decided among those six rules. The pattern of the adopted rule is defined as the contour direction, and the inference result of the rule is defined as the contour intensity respectively. The same inference is performed also with the hue value of each pixel, and the contour direction and intensity are calculated for each pixel. Then an AND or OR operation is carried out between the contour intensity calculated by the inference of the lightness value and the contour intensity calculated by the inference of the hue value. Furthermore the chroma saturation of each pixel value is used as the load value. In such a constitution applying the fuzzy inference, the contour of a color image is extracted.

Title: Liquid crystal display circuit
Inventor: SHIRAKAWA HIROSHI
IPC: G09G3/18
Filed: 1995-04-19
Abstract: PURPOSE: To make a liquid crystal display circuit possible to perform various expressions even by a low cost model by dividing at least one of a common signal side or a segment signal side into two signal systems and making one of the systems selective. CONSTITUTION: When a transistor TR1 is turned on by a switching control signal CONT 1, a common signal COM1 related to an 'A' display is rectified by a resistor R1 and a capacitor C1 and becomes an intermediate voltage. Then, the potential difference between the COM1 and a segment signal SEG becomes lower than a turning-on level and the 'A' display becomes a turning-off condition. On the other hand, when the transistor TR1 is turned off by the signal CONT1, the signal COM1 is fed to a common electrode side through the resistor R1 and the signal SEG is given to the segment related to the 'A' display. Since the potential difference between the signals COM1 and SEG becomes a driving voltage, the 'A' display is turned on.
