Abstract: An image forming apparatus includes a frame body, a frame cover supported by the frame body so as to be capable of opening and closing, an image forming unit that forms a toner image on an image carrier, a cleaning unit that removes and collects residual toner from the image carrier, and a toner container for accumulating the toner collected by the cleaning unit. The toner container is supported by the frame cover.

Abstract: The invention provides a method of the preparation of a citrus concentrated aroma component which has flavorous strength sufficient to be used as a flavor and fragrance's raw material, imparts a fresh feeling, fruit juice feeling and natural feeling to drinks or flavorous compositions and also has an effect of masking the smell of citrus juice caused by heating. The method of producing a citrus concentrated aroma includes concentrating fruit juice continuously under reduced pressure such that the concentration of flavorous components is in excess of 100 to 150 times that of the fruit juice until the alcohol content is increased up to 1 to 7% by weight, adding a filtering aid to the concentrated citrus recovery solution to carry out filtration and floating and separating the essence oil.

Abstract: The present invention relates to a wireless communication system which suppresses the quantity of an electric power of a carrier wave consumed in communicating by a digital data as well as it can improve the communication quality. The wireless communication system according to the present invention includes at least a signal processing circuit section and a high frequency transmitter/receiver section and it comprises controlling the timing of modulation completion by the digital data signal with the transmitting timing of the modulation carrier wave supplied from the electric power amplification section of the high frequency transmitter/receiver section and a control circuit which controls the operation of the high frequency transmitter/receiver section in transmitting the modulation carrier wave on the basis of the preceded timing of the modulation completion.
