Title: Electrophotographic method
Inventor: OKADO KENJI
IPC: G03G9/083
Filed: 1986-01-21
Abstract: PURPOSE:To prevent particles from being filmed on a latent image carrier when no latent image is formed by sticking a lubricant having the negative polarity positively on the latent image carrier. CONSTITUTION:A particle group with the opposite polarity which sticks on a drum 1 is removed by a cleaning member 15. At this time, even an image is absent and a control means 11 turns off a transfer charger 14 to guide the particle groups with the opposite polarity on the surface of the drum 1 to the member 15. Therefore, when no image is formed, the particle group with the opposite polarity is removed positively from on a sleeve 6, and thus the particle group with the opposite polarity due to the negatively charged lubricant is removed and particulate toner sticking strongly on particles with the opposite polarity is removed in normal copying operation. Further, the particles with the opposite polarity stick on the drum uniformly and prevented from being filmed.

Title: Heat exchanger
Inventor: WATANABE KAZUFUMI
IPC: F28D9/00
Filed: 1986-01-20
Abstract: PURPOSE:To subject not only sensible heat but also latent heat (water content) to heat exchange so as to improve the heat-exchange efficiency of the heat exchanger, by attaching a moisture absorbent to the front surface of a vessel in which a heat storage material is sealed. CONSTITUTION:On the front surface of a vessel 2 in which a heat storage material 1 is sealed, heat exchange elements 4 in each of which silica gel or that impregnated with calcium chloride is attached onto the whole surface are arranged with clearances which are required for passing heat media therebetween, thereby to form a heat exchanger 5. At the space heating time, when indoor air is caused to flow through the heat exchanger 5, sensible heat is stored in a heat storage material 1, and latent heat (water content) is absorbed of its humidity by means of a moisture absorbent 3 on the front surface of the vessel 2. When the heat storage and moisture absorption approach a saturated state, external air of low temperature and low moisture on the outdoor side enters into the heat exchanger 5, receiving the sensible heat from the heat storage material 1 and being warmed, further receiving the latent heat (water content) from the moisture absorbent 3, being heated to a high humidity as compared with that of indoor air, and being sent into the room. As described above, not only the sensible heat possessed by indoor air but also the latent heat (water content) due to the moisture absorbent 3 can be efficiently recovered.
