Abstract: An air conditioning apparatus for an electric car capable of preventing condensation from forming on windshields, while decreasing electric power consumption. A duct forms therein a first passageway connecting an inside air inlet 8 with a lower outlet (foot outlet) 10 for discharging an air flow toward a lower part of a passenger in a cabin, and a second passageway for connecting an outside air inlet 11 with a defroster outlet 12 for discharging an air flow toward an inside surface of a windshield. A heat exchanger(s) is (are) arranged in the duct to make contact with the flow of air in the first and second passageways so as to heat the flows of air therein. The inside air after being heated by the heat exchanger is discharged from the lower outlet 10 to the cabin, while the outside air after heating is discharged from the defroster outlet 12 toward the windshield.

Abstract: The method and apparatus providing for the conversion of phonetic symbols to kanji characters. Phonetic symbols, such as kana symbols, are converted to corresponding kanji characters by inputting the phonetic symbol, converting the phonetic symbol to a kanji character corresponding to the phonetic symbol, displaying the resulting kanji character to permit confirmation of the accuracy of the conversion. Alternatively, the input phonetic symbol may be converted to a corresponding kanji character by inputting the phonetic symbol as well as the approximate number of kanji strokes corresponding to the kanji character, which corresponds to the input phonetic symbol, converting the phonetic symbol based on this input and displaying the resulting kanji character on a display apparatus for confirmation of the accuracy of the conversion process. In both cases, if the displayed kanji character is not correct, the next kanji character in the dictionary corresponding to the input phonetic symbol will be displayed.

Abstract: In a conveyor system of dust containers for using in a building, particularly an apartment house, dust discarded from respective houses is contained in a cylindrical polysheet, which is clipped at separated points to form dust capsules having a smaller diameter than the inner diameter of a vertical chute so that the capsules in the chute are subjected to air resistance. A pressure detector is provided near the bottom of the chute. In response to the output of the pressure detector the quantity of air escaping to the outside from the upper end of the chute is controlled so that the falling speed of the capsule is adjusted to a safe value.
