Title: Electric dust collector
Inventor: MASUDA SENICHI
IPC: B03C3/36
Filed: 1979-02-03
Abstract: PURPOSE: To enhance the efficiency of dust collection by providing perforated plates in the direction of interrupting the flow of gas at a place on the gas inlet side of dust collecting electrode.  
     CONSTITUTION: Plural numbers of metal perforated plates 17 and ventilating plates 18 are provided in such a way as to partition the inlet flue 3 of an electric dust collector. During passage through small holes 16 of the perforated plates 17, gas is rapidly cooled by the heat radiation of the perforated plate 17 itself and pressure drop encountered upon passage of the gas through the small holes. As the temperature falls, moisture is condensed and then dust present in the gas is adsorbed in the condensed water and gradually grows to greater particle aggregates. In these processes, dust of a grain size of approx. 0.01 microns is coarsened to a grain size of 1W10 microns after approx. 1/100sec especially a grain size of approx. 100 microns at largest, so that the efficiency of dust collection can be raised.

Title: Water level detecting device for electric jar pot
Inventor: KOIDE HIROYUKI
IPC: A47J27/21
Filed: 1988-01-21
Abstract: PURPOSE:To enable a water level to be easily confirmed even from outside by a float while correctly detecting the water level of an electric jar pot easily controlling electrification to the pot by providing the float, forming its bottom surface as the reflector of an ultrasonic wave, in the inside of a water quantity display pipe and a water level detecting ultrasonic vibrating element in the bottom part of the water quantity display pipe. CONSTITUTION:An emitted ultrasonic wave is propagated in the inside of a water quantity display pipe 5, but the ultrasonic wave is reflected in a position reaching the bottom surface of a float 6 floating in the water quantity display pipe 5, returning as a reflected wave to an ultrasonic vibrating element 4. This reflected wave is amplified by an amplifier 7 and clearly discriminated from the emitted wave by a masking pulse generator 9 through a detected waveform shaping circuit 8, and only the reflected wave is input to a control element 10. Since the propagation time of the ultrasonic wave in the water is in proportion to a distance, the control element 10 measures the time, after the ultrasonic wave is emitted till it reflectively returns, detecting a water level, and being based on the result, a display of the water level and an electrification stop or the like to a heater, in the time of a low water level can be controlled. While because the float 6 enables the water level to be visibly shown from the outside simultaneously through an opening part 11 of a case, the water level is clearly displayed.

Filed: 1987-01-23
Abstract: PURPOSE:To maintain high picture quality by forming a 2nd electrostatic latent image by a light output device by using a data in the page memory while forming the 2nd electrostatic latent image by an image formation optical system in 2nd scanning. CONSTITUTION:A light image is read by an image reader 5 in 1st scanning and a 1st electrostatic latent image and the 2nd electrostatic latent image area formed on a photosensitive body 9a in the 2nd scanning. Those two scans need not be made in the same direction and it is possible that one is a forward scan and the other is a backward scan. In this case, the scanning speeds of the forward scan and backward scan are set to the same speed. When >=2 copies are taken continuously by using the same original 1, The formation of the 2nd electrostatic latent image by the image formation optical system 7 requires one scan for each copy without fail, but the read signal obtained by the image reader 5 is stored in the memory, so scanning need not be performed more than once. Consequently, transfer to a copying form is performed only once and copies of high picture quality are taken.
