Abstract: PURPOSE:To allow a card possessing person to designate a desirable graphic as password information, and to obtain an excellent individual discriminating system by providing a password information input means consisting of a card write means, a graphic recognizing means and a brushstroke strength detecting means. CONSTITUTION:A password information input means 6, which consists of a card write means 3 to write the password information into a card by means of a just card possessing person, a graphic recognizing means 6a to recognize and display the traced graphic, and a brushstroke strength detecting means 6b to detect the brushstroke strength at the time of inputting the figure, is provided. Thus the card possessing person can designate not a fixed figure but the desirable graphic as the password information, and based on the brushstroke strength at the time of inputting the graphic, whether or not the card possessing person is the just card owner can be discriminated.

Abstract: PURPOSE:To prevent a third party from decoding a password number by providing a selecting means, which selects a single type of a figure out of the figures of a display means, a confirming means, and a panel, where the display means is provided at a position more hollow than a front surface. CONSTITUTION:A password number input means consists of a display means 21 to display the figures, a selecting means 22 to select a single type of the figure out of the figures on the display means 21, a confirming means 23 to confirm the selected figures, and a panel 24 where the display means 21 is provided at the position more hollow than the front surface. Consequently when a card possessing person inputs the password number, since the display means 21 is provided at the position more hollow than the front surface, it cannot be seen by the third party, and the motion of the finger of the card possessing person is only the operation of the selecting key 22 and the confirming key 23. Thus the third party cannot decode the password number by the input operation of the password number.

Abstract: PROBLEM TO BE SOLVED: To restrict a high harmonic current of an input AC power supply without using any switching element in a refrigerator in which a compressor is driven with an inverter on the basis of a DC power supply attained by regulating flow of the AC current and smoothening it. SOLUTION: A high harmonic wave distortion factor of an AC current from an input AC power supply 1 is detected by a current distortion sensing means 11. It is discriminated by a current distortion discriminating means 12 whether or not this high harmonic distortion factor exceeds an electrical power proportional limit value. In the case that the distortion factor exceeds the limit value, the number of rotation of a motor for a compressor 5 is increased by a motor control means 13, a relative electric power is increased and a high harmonic distortion factor of the AC current is decreased, resulting in that it is possible to restrict the high harmonic current of the input AC current 1.

Abstract: PROBLEM TO BE SOLVED: To prevent a harmonic current from having an effect on a commercial power supply by providing a refrigerator with a battery being charged during stoppage of a compressor when the harmonic distortion has an insignificant effect and disconnecting an input AC power supply during operation of the compressor when the harmonic distortion has a significant effect and supplying power from the battery. SOLUTION: An inner temperature detecting means 10 detects the temperature in a refrigerator through a temperature sensor 9 and a motor control means 11 makes a decision whether the inner temperature detected through the inner temperature detecting means 10 is high or low. If the temperature is low, an inverter section 4 is controlled to stop a compressor 5 and a switch A7 is turned on while a switch B8 is turned off to charge a battery 6. If the temperature is high, the motor control means 11 turns off the switch A7 and turns on the switch B8 to discharge the battery 6 and the inverter section 4 is controlled to operate the compressor 5. According to the arrangement, the effect of harmonic distortion on an input AC power supply 1 can be suppressed during operation of the compressor 5 when the harmonic distortion has a significant effect.

Abstract: PURPOSE: To retain a cooling function of a refrigerator even in the case where communications between a main controlling unit for controlling the whole refrigerator and a sub-controlling unit for controlling a compressor have become defective in the refrigerator for cooling and storing foodstuffs. CONSTITUTION: A controller for a refrigerator comprises an I/F abnormality detecting means for detecting the abnormality of communications, a compressor operation condition determining means 66 for detecting indirectly the operational. condition of a compressor, a compressor controlling means 42, a timer 82 for starting/stopping the operation of the compressor and an integrating counter 71 for integrating an operation time. When communications are abnormal, in-chamber temperatures are controlled, the compressor is cooled and an evaporator 13 is defrosted.

Abstract: PURPOSE:To finely control the temperature of a freezer-refrigerator for freezing and chilling food. CONSTITUTION:A freezer compartment and a refrigerator compartment each include temperature sensors, a temperature increase-calculating means 32a for the freeze chamber ands the cold storage chamber, a chamber temperature difference-calculating means 32b for the two chambers, and an outdoor temperature detective means 31. A fuzzy inference processor 34 performs fuzzy logic operation on the basis of the degree of the increase of temperature, the difference in temperature in the chamber, and the outdoor temperature and according to control rules extracted from a memory 33, and obtains the degree by which the set temperature is to be lowered; on the basis of the result, a set temperature-calculating means 35 adjusts the set temperature. In accordance with the result, the compressor, fan, and a motor-operated damper are controlled.

Abstract: PURPOSE:To provide a controller for a freeze refrigerator that eliminates a rise in temperature of foods due to insufficient precooling or due to an excess of precooling by carrying out precooling right before defrosting according to the largeness of thermal load to the foods in the refrigerating member. CONSTITUTION:The temperature in the subject refrigerating refrigerator is detected by a temperature sensor 21, and when a cumulative time counter 22 for the operation of a compressor counts a set time, the cooling time from the standard value of a second-standard circuit 25 to the standard value of a fourth standard circuit 32 is measured by a cooling time measurement means 31. From this cooling time and the ambient temperature detected by an ambient temperature sensor 30 a fuzzy-theoretical calculation is carried out based on a control rule taken out from a memory 34 by a fuzzy inference processor 33 to determine the time of precooling and precooling time is set by a time setting means 35 for the timer.
