Title: Method of removing form of lining molded underground
Inventor: HAYASHI MITSUTOSHI
IPC: F16L1/024
Filed: 1994-03-14
Abstract: PURPOSE:To readily advance a cylindrical form to construct a long pipe line, by providing recessed grooves at the outer diameter face of the cylindrical form to force the cylindrical form to do an axially reciprocal movement to form a clearance between the outer diameter face of the form and the lining inner face. CONSTITUTION:A cylindrical form 22 provided with recessed grooves 122 at the outer diameter face is axially and reciprocally moved in the not-yet-cured mortar filled in the space 26 of the outer diameter of the cylindrical form 22. The inside face of the mortar 24 is shaved by the side wall 126 of the recessed grooves 122 and a space is formed between the outer periphery of the form 22 and the mortar 24. The reciprocal movement is continued until the mortar 24 is cured, to facilitate the formation of the clearance between the mortar and the form. In this way, the lining 40 can easily be formed in the underground and a steel pipe is slid to advance and smoothly construct a long pipeline.

Title: Cleaning device and electrophotographic image forming device
Inventor: NAGAOKA TOMOO
IPC: G03G21/16
Filed: 1995-03-02
Abstract: PURPOSE:To provide a cleaning device that can clean a cleaned body desirably, and an image forming device by providing exhaust ports at plural faces of a filter housing so as to lower the exhaust resistance. CONSTITUTION:Plural exhaust ports 20a are formed over the whole face of a filter housing 20. Air entering a brush case 3 is therefore exhausted upward, backward and downward as shown by arrow marks a-d, so that resistance at the exhaust time is suppressed low. Toner sucked into the brush case 3 is therefore conveyed in the directions of arrow marks in the brush case 3 and collected positively by a filter 22 so as to prevent the generation of such defectiveness that the toner once sucked into the brush case 3 flows backward and blows off outside of the brush case 3 from the periphery of a rotary brush 2. Such a problem that the interior of a machine is polutted by the blown-off toner is also solved. The quality of formed images can be therefore heightened.

Abstract: PURPOSE:To contrive to ignite stabilizedly at a nozzle tip, by recessing the tip of a center pipe a little backward from that of an inner pipe, at the ends of a center pipe and an inner pipe which are electrically insulated from each other. CONSTITUTION:When combustion gas is ignited, a recessed part 22 formed on the face at the tip of a center pipe 18 can function as follows. That is, combustion gas stagnating in the recessed part 22 formed on the face at the tip of a center pipe 18 can be ignited, when an arc, discharged between the internal periphery at the tip of an inner pipe 17 and the non-coated part 24 on the external periphery at the tip of a center pipe 18, ignites combustion gas which is injected from the tips of an outer pipe 16 and an inner pipe 17. The combustion gas ignited in the recessed part 22 becomes a fire ball, which promotes ignition to combustion gas passing through a nozzle tip successively. By forming a fire ball, flames will not be blown away, and stabilized ignition can be taken place at the burner tip.
