Title: Image forming device
Inventor: ONO KAZURO
IPC: G03G15/16
Filed: 1992-12-29
Abstract: PURPOSE:To improve the ability to clear away residual toner on an intermediate transfer roller. CONSTITUTION:The intermediate transfer roller 6 is arranged in contact with a photosensitive drum 1. A toner image is formed on the photosensitive drum 1 by a development device 5, etc. This toner image is transferred onto a transfer roller 6 by the application of a voltage 7a of the same polarity as the toner. Thereafter, by the application of a voltage 7b of the same polarity as the toner, the toner image is retransferred to a transfer material P inserted in a nip part between the photosensitive drum 1 and the transfer roller 6. At this time, the toner that has not been retransferred to the transfer material P remains on the surface of the transfer roller 6. This residual toner is returned onto the photosensitive drum 1 by the impression of a cleaning bias with the polarity opposite to that of the toner to the transfer roller 6. By impressing an Ac bias as the cleaning bias, on which a DC bias overlaps, the residual toner is vibrated to be separated from the transfer roller 6 easily.

Abstract: PROBLEM TO BE SOLVED: To precipitate a plankton by inactivating that by a method wherein a phytoplankton of a water bloom, red water or the like which are generated by eutrophiction in river, sea area, lakes, ponds, etc., are irradiated with ultrasonic waves of a specific frequency in water. SOLUTION: When plankton cells of water bloom, red water or the like are irradiated with ultrasonic waves, the cells are inactivated, photosynthesis capacity is impeded, and they come to be easily precipitated. By executing such the precipitation treatment, the water bloom, red water, etc., are attempted to be excluded. A boat 2 is floated on a pond 1 in which the water bloom is generated when executed, and an inside of water 3 is irradiated with ultrasonic waves of 20 kiloherz or over frequency from a ultrasonic generator at suitable sounding intervals. An irradiation time at that time is determined according to a generation state of the water bloom. Further, excepting irradiation with ultrasonic waves under a state of floating the ship on the pond, water of the pond is circulated, the water under this circulation process is irradiated with ultrasonic waves, and defects are preferably attempted to be excluded thereby.

Title: Cavitation detection method and microphone with acoustic filter
Inventor: SATO MASANORI
IPC: B06B1/06
Filed: 1997-12-30
Abstract: PROBLEM TO BE SOLVED: To detect whether or not cavitation takes place in a liquid in a vessel at ultrasonic wave washing. SOLUTION: A liquid 8 is put in a vessel 7 on a bottom of which an ultrasonic vibrator 6 is mounted, while a microphone 5 with an acoustic filter and a microphone 9 without the filter are inserted in the liquid 8. When an ultrasonic wave from the ultrasonic wave vibrator 6 is emitted in the liquid 8, a longitudinal wave of the ultrasonic wave is delivered respectively to the microphone 5 with an acoustic filter and the microphone 9 without the filter. The microphone 5 with an acoustic filter detects only the longitudinal wave and the microphone 9 without the filter detects a 1/2 sub-harmonic in addition to the longitudinal wave. Since a surface wave generated by cavitation is detected by comparing outputs of the two microphones, the cavitation is surely detected.  Since the microphone with the acoustic filter can reduce the effect of the surface wave, this method is advantageous to detect cavitation.

Title: Recycling of foamed polystyrene
Inventor: SUGANUMA KAZUO
IPC: B09B3/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To contrive the volume-reduction of a foamed polystyrene and the reuse as a foamed polystyrene. SOLUTION: Acetone can not cleave the interaction on a benzene ring in a polystyrene mol which is a main component of a foamed polystyrene, so that the molecular structure of the polystyrene can not be broken into pieces, but the polystyrene comes to a paste state because of the disappearance of air portion inside the foamed polystyrene. This method can contrive the volume- reduction of a foamed polystyrene and can provide a reuse as a foamed polystyrene by heating the paste polystyrene as it is. The solvent acetone is to be reused after being vaporized and liquefied by cooling. In conclusion, the reaction of a waste foamed polystyrene with a solvent gives a paste polystyrene. An apparatus is capable of recovering the solvent to be reused, and the formed paste polystyrene can be used as a foamed polystyrene again with a heat energy.
