Title: Developing device
Inventor: NISHINA SHUJI
IPC: G03G15/08
Filed: 1987-12-11
Abstract: PURPOSE:To stabilize toner supply by making a sheet of plastic whose thickness is specified. CONSTITUTION:The sheet 8 for toner supply has its one end fixed to a take-up shaft 6 and the other end adhered and fixed 5d to the tip of the upper part of an opening 5a after toner 7 is charged. This sheet 8 is made of plastic, whose thickness is specified in the range from 10-100mum to prevent the sheet 8 from curling up and slackening. Further, when the sheet 8 is formed of a single-body material, the thickness is best about 20mum and when the sheet is formed of a compound material, the thickness is best about 60mum by the composition of polyester and polyethylene. This compound material can be heat-sealed, so it becomes easy to fix one end of the sheet 8 to the upper tip 5d of the opening 5a for toner supply. Consequently, the supply of the toner by the developing device which supplies the toner to a development part is stabilized.

Title: Penetration method for caisson foundation
Inventor: MASUI NAOKI
IPC: E02D23/08
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To provide an efficient penetration method for a caisson foundation by reducing the hydraulic gradient of a skirt part. SOLUTION: A caisson 12 has a caisson main body 12a, a top board 12b, a bottom board 12c, and a skirt part 12d. A water-impermeable layer 18 is formed on water bottom ground 10 before the caisson 12 is sunk into place. The water-impermeable layer 18 has a high fluidity and viscosity and is so formed to have a predetermined width from the part of the skirt part 12d to be grounded to its outer periphery. Next, the skirt part 12d is sunk into place so as to be grounded on the water-impermeable layer 18, with the end of the skirt part 12d passing through the water-impermeable layer 18 and slightly penetrating the water bottom ground 10 to decompress the inside of a lower cell 16. The skirt part 12d is made to penetrate the water bottom ground 10 by suction load.  In this case, the water-impermeable layer 18 present on the outer periphery of the skirt part 12d increases the infiltration distance of water and decreases a hydraulic gradient, thus making it possible to prevent soil and water from flowing into the skirt part 12d.

Title: Method and apparatus for manufacturing x-ray reflection mirror of multilayer film
Inventor: OSHINO TETSUYA
IPC: G21K1/06
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To obtain an X ray-reflecting mirror of a multilayer film having a reflecting face of a small shape error, by measuring a shape of the reflecting face of the multilayer film while the film is being formed, and controlling a film thickness distribution based on the measured result. SOLUTION: Vapor deposition particles 6 projected from a vapor deposition source 1 reach a substrate 3 of a reflecting mirror through a film thickness distribution- controlling mechanism 2 and are accumulated on the substrate 3. The mechanism 2 controls a spatial distribution of the particles 6 moving from the source 1 to the substrate 3. The mechanism 2 works also as a mask mechanism to catch a part of the entering particles 6 and convert a distribution of the particles 6 after passing through the mechanism 2 to a required distribution. The part of the particles 6 are caught by a rotating mask not to reach the substrate 3. A distribution of the particles 6 reaching the substrate 3 is controlled by a shape of an edge of the mask and a rotating speed of the mask.  While a multilayer film is being formed, a shape of a reflecting face is measured by a measuring mechanism 4 and the controlling mechanism 2 is driven by a mechanism-controlling part 5 so that the shape of the reflecting face becomes a required shape.

Abstract: PURPOSE:To maintain high quality and high speed printing operation even for long time printing or under high temperature by arranging caps or brushing mechanisms, delivering or sucking very small amount of ink from a head nozzle for printing operation longer than a predetermined time, at plural points in the moving zone of carriage. CONSTITUTION:Upon receiving of a print signal, a carriage 16 moves into a printing area thus keeping up printing operation. Upon elapse of predetermined time set in a timer, refresh operation takes place and printing operation is carried out untill the carriage 16 arrives the left end then a very small amount of ink is delivered toward the belt part of a cleaner 24 located at the left end. When the print signal is further provided and a predetermined time set in a capping timer elapses, printing operation is interrupted upon completion of a line of printing. Capping is performed through a right end suction cap 4' if the stop position of the carriage 16 is at or close to the right end, through a left end cap 4 if the stop position is at or close to the left end, and through a cap in the printing direction prevailing before stoppage of the carriage 16 if the stop position is in the central part. By such arrangement, moving time of carriage required for capping operation can be shortened.
