Patent JP-S6364038-A (JP)
Title: Original reader
Inventor: AOKI YOSHINORI
IPC: H04N1/00
Filed: 1986-09-05
Abstract: PURPOSE:To automatically read the size of an original by providing an original platen provided with plural transparent electrodes and providing an original retaining plate with electrodes so that they are brought into contact with said transparent electrodes and preventing the short-circuit of the electrode in the set position at the time of setting the original. CONSTITUTION:Plural transparent electrodes 12 are provided at equal intervals on an original platen 11 consisting of a transparent glass plate. Plural electrodes 14 are provided at equal intervals on an original retaining plate 13. They are so constituted that transparent electrodes 12 and electrodes 14 cross at a right angles and are brought into contact with each other when the original platen 11 is pressed with the original retaining plate 13. When an original 15 is placed on the original platen 11 and is pressed with the original retaining plate 13, transparent electrodes and electrodes 14 in the part where the original 15 exists are not brought into contact with each other, but those in the part where the original 15 does not exist are brought into contact with each other and are short-circuited. Transparent electrodes and electrodes 14 are connected to a control circuit to detect the short-circuit position. Since the original platen 11 and the original retaining plate 13 are provided with electrodes and are short-circuited in the original set position, the image is automatically read in accordance with the size of the original.

Title: Preservation of liposome
Inventor: YAMAGUCHI JIRO
IPC: A61K47/20
Filed: 1989-08-14
Abstract: PURPOSE:To reinforce the membrane structure and remarkably inhibit aggregation during storage by adding an aminoalkanesulfonic acid to a liposome dispersion. CONSTITUTION:A liposome containing encapsulated substances such as an anti- cancer agent, an anti-viral agent, an antibiotics, a peptide hormone and a phospholipid is prepared and the resultant liposome dispersion is preserved by adding an aminoalkanesulfonic acid (e.g. compound such as one represented by formula I) thereto. The above-mentioned method is utilized especially in case of a liposome composed of a phospholipid and/or a glycolipid and cholesterol. The amount of the aminoalkanesulfonic acid added is suitably 0.2-15 pts.wt. based on 100 pts.wt. liposome dispersion. This preservation method is effective to inhibit aggregation in storage of a liposome produced by dispersing a lipid into water in a liquid state.

Title: Heat-pipe working fluid conduit assembly
Inventor: RURUFU YAN MEEIERU
IPC: F28D15/02
Filed: 1989-08-16
Abstract: PURPOSE: To minimize entrainment of liquid within transmitted vapor by joining a flared shell to a heat exchanger thereby reducing the velocity of vaporized heat pipe working fluid entering into the heat exchanger and providing an independent liquid return duct providing additional isolation of the liquid and vapor phases in the outer tube of the conduit. CONSTITUTION: The heat pipe conduit assembly 32 has a flared shell 44 having cross-sectional area increasing as the conduit approaches a bundle 38. Cross-sectional area larger than that of a main tube section 46 constituting the remaining part of the assembly 32 reduces the velocity of incoming vaporized working fluid in a region where the liquid touches the bundle 38. Such reduced velocity minimizes entrainment of liquid. Other countermeasure means includes an independent liquid return duct 48 having significantly smaller cross-sectional area than the main tube 46 and disposed in the main tube 46 and the shell 44. Since the duct 48 is located along the lowermost face of the shell 44, liquid collected in that region is introduced gravitationally to the duct 48.

Title: Sheet breakage preventive method for press roll
Inventor: TAGUCHI TOSHIO
IPC: B41F13/02
Filed: 1984-10-11
Abstract: PURPOSE:To prevent breakage of paper by pressing a non-driven wide press roller, installed in a triangle plate drag roller part, to this drag roller only during slow operation, and thereby reducing local tension unbalance on the web likely to be otherwise generated during slow operation. CONSTITUTION:During slow operation, the printing unit 2 is in condition with the drum removed, while the transport path for web 1 remains the same as in high-speed operation, so that no printing is made on the web 1 throughout its width. The condition of the printing unit 2, i.e. whether the drum is set on or removed, is sensed by a drum sensor 10, and the signal obtained is sent to a control device 11. As the printing unit 2 is, at this time, free of the drum, a signal is given from said control unit 11 to a press roller set-on/removal device 9 to indicate that a wider press roller 5' shall be pressed toward a triangle drag roller 4. During slow operation, both the narrow 5 and wide 5' press rollers press and hold the web 1 by its greater width portion, which may reduce tension unbalance likely to be generated in the drag roller part 4 by the press rollers 5, 5'. Thus the paper is prevented from breakage.
