Title: Continuously pressurizing device
Inventor: OKAJIMA KIYOTAKA
IPC: B29C43/44
Filed: 1987-04-25
Abstract: PURPOSE:To make it possible to easily equalize the inner pressures in respective pressurizing chambers without especially providing pressure measuring device and pressure controlling device by a method wherein the respective pressurizing chambers of a continuously pressurizing device are connected to each other by a fluid communicating pipe. CONSTITUTION:Pressurizing fluid 6 is poured respectively in fixed pressurizing chambers 4a and 4b so as to circulate in the respective fixed pressurizing chambers 4a and 4b in order to pressurize endless steel belts 2a and 2b under uniform surface pressure, which pressurizes a matter to be compressed 3 under uniform surface pressure. At this time, even when the difference develops between the pressures of the pressurizing fluids 6 which are respectively supplied to the pressurizing chambers 4a and 4b, the pressures in the pressurizing chambers 4a and 4b immediately equalize with each other, since the respective pressurizing chambers 4a and 4b communicate with each other by a fluid communicating pipe 8, which respectively connects to fluid feed pipes 5a and 5b. Further, the matter to be compressed 3 can be heated or cooled by means of the temperature difference between the pressurizing fluid 6 and the belts 2a and 2b. Furthermore, by pouring sealing fluid, the pressure which is higher than that of the respective pressurizing fluids 6 in the pressurizing chambers 4a and 4b, in peripheral edge parts 9a flow out of the peripheral edge parts 9a, to form stable thin films in gaps made between the peripheral edge parts 9a and the belts 2a and 2b.

Title: Method for compressing data in page printer
Inventor: TAKAHASHI YOSHINORI
IPC: H04N1/413
Filed: 1995-04-04
Abstract: PURPOSE: To obtain high compressibility corresponding to the picture contents of printing image data at the time of compressing the data. CONSTITUTION: Image data 1 are constituted of a set of element points to be printed by a printer. The image data 1 are compressed by breaking them down to lines in the main scanning direction, i.e., strings of element points arranged in the direction and also breaking them down into lines in the sub-scanning direction. The compressibility of a compressing method in either one of both scanning directions becomes higher in accordance with the contents of a picture. When compression information 2 indicating the compression method of higher compressibility is added to compressed data 3 obtained by the compression method and outputted, the most efficient data compression for the rectangular area concerned can be attained.

IPC: G03G5/00
Filed: 1995-04-27
Abstract: PURPOSE: To efficiently regenerate the electrically conductive substrate of a photoreceptor while suppressing the occurrence of problem on environmental hygiene by immersing the photoreceptor in a water-soluble solvent which dissolves a resin binder and removing the photoconductive layer by dissolution. CONSTITUTION: An electrophotographic photoreceptor with a photoconductive layer contg. a photoconductive material and a resin binder on the electrically conductive substrate is immersed in a water-soluble solvent which dissolves the resin binder and the photoconductive layer is removed by dissolution. Since the solubility of the dissolved component in the water-soluble solvent is rapidly reduced by adding water to the solvent, the dissolved component is deposited by adding water and can be separated from the solvent. The solvent freed of most of the dissolved component can easily be regenerated by distillation. The solvent is preferably N-methyl-2-pyrrolidone.
