IPC: F16J15/16
Filed: 1987-03-14
Abstract: PURPOSE:To prevent any wear of a water leakage prevention structure by interposing a rubber cylinder as a joint between an outer casing for a screw shaft and a bearing with an oil seal with a sleeve. CONSTITUTION:The screw side of a screw shaft 1 is surrounded by a screw shaft outer casing 2, and this screw shaft outer casing 2 and a gland packing 3 are connected to each other through a rubber cylinder 5.

IPC: G03G5/14
Filed: 1991-03-25
Abstract: PURPOSE:To obtain a function separated type laminated organic photosensitive body which is high in sensitivity, excellent in chargeability, and low in residual potential and provides images with a small characteristic change due to environment and a proper image quality. CONSTITUTION:In a sensitizing body constituted by sequentially laminating an under coating layer 2 and a sensitizing layer 3 on a conductive base 1, a micro amount of phosphorus is included in the under coating layer. At this time, it is favorable to form the under coating layer by a material with an epoxy resin as the main component since characteristic change particularly due to environment becomes small. In that case, it is desirable to have phosphorus included within the concentration range of more than 30 weight ppm and less than 500 weight ppm against the epoxy resin. Also, the under coating layer is formed by a material in which a compound represented by a constitutional formula (I) is included in polyvinyl alcohol. Besides polyamide resin soluble in alcohol may be included within the range under 50weight%.

Title: Liquid jet recorder
Inventor: HIGUCHI KAZUHIKO
IPC: B41J2/175
Filed: 1985-03-26
Abstract: PURPOSE:To largely shorten recording time and save a film material being used, by providing ink-supplying means on both sides of a recording head. CONSTITUTION:An ink-supplying part 3a supplies an ink from an ink reservoir, and the ink is supplied to a perforated film 4 by frictional contact. The film 4 supplied with the ink is brought into a recording head 2 by taking it up by a reel, and ejects the ink to a recording paper 1, thereby obtaining a recorded image 18. In recording in the next line, the part 3a is released from the contact with the film 4, while an ink-supplying part 3b is brought into contact with the film 4. The film 4 thus supplied with an ink is brought into frictional contact with the head 2 to perform recording, and is taken up by a reel, while the head 2 is opposed to the paper 1 and moved in a direction opposite to an arrow A, whereby recording is sequentially conducted. Accordingly, since the recording head is reciprocated on the recording paper and recording is conducted in both directions, the recording time can be markedly shortened.

The liquid crystal dispersion film 13 is preferably 2-15mum thick, and more preferably 3-10mum. If the film is too thin, enough scattering property for light of the dispersion film 13 is not obtd. If the film is too thick, the driving voltage becomes too high, which does not give enough contrast. Such an selective light reflecting element 20 or the like that transmits incident light with a specified range of incident angle including the direction to the observer but reflects or scatters light with incident angle out of this range is formed on the opposite side to the observer of the liquid crystal dispersion layer 13.
