Title: Fine powder coal burning type water pipe boiler
Inventor: OHASHI SEIJI
IPC: F23J1/00
Filed: 1986-05-02
Abstract: PURPOSE:To make a compact boiler unit by a method wherein water pipe wall surface at a furnace bottom of a combustion chamber comprises for the most part gradually inclined surfaces and the lowest part of substantial horizontal surface, and is uniformly covered with refractory materials, with a plurality of ash discharging holes having V-shaped notches arranged at the lowest part. CONSTITUTION:Since wall pipe wall surfaces 3 at a furnace bottom of a combustion chamber 1 of a boiler are uniformly covered with refractory material 5, ashes in the combustion chamber are dropped onto the refractory material at the furnace bottom. The ashes on the refractory material are not directly contacted with the water pipes, so that they may show a slight lower degree of cooling action than that of bare water pipe walls, the surface of accumulated ashes is heated by a radiation heat within the combustion chamber and then melted therein. The melted ashes flow down along the gradually inclined surface and are accumulated at the lowest part 4. Since the lowest part is provided with a plurality of ash discharging holes 6 enclosed by encircling refractory material having V-shaped notches 11, as the melted ashes are accumulated at the lowest part to pile up to a certain height or a thickness (100 mm or so), the ashes are overflown from the V-shaped notches into the ash discharging holes and then discharged in suquence. Therefore, it is not necessary to make an sharply inclined furnace bottom shape.

Title: Fiber break detection method for carbon fiber reinforced plastic tube
Inventor: KUBOMURA KENJI
IPC: G01N27/90
Filed: 1994-04-15
Abstract: PURPOSE:To provide a method for detecting fiber break by using a rectangular excitation coil for making induction current selectively flow in each direction of the reinforced fiber of carbon fabric reinforced plastic tube. CONSTITUTION:Due to an excitation coil 10a wound around the periphery of CFRP (carbon fiber reinforced plastic) tube l. alternating field H takes place in the direction of tube's axis, and thanks to the magnetic field H, induction current i flaws in the axis direction of the tube 1. Diamagnetic field h takes place based on the induction current i, so, the impedance of a detection coil 10b changes. The detection coil 10b is wound along the inside of the excitation coil 10a. Since, in a carbon fiber reinforced plastic, the electric resistance in the direction of carbon fiber is lower than in perpendicular direction by about three digits, the induction current selectively flows in the fiber direction of 0 deg. direction. Therefore, if fiber break exists in that direction, electric resistance will increase, with the result of decrease in the induction current i and Diamagnetic field h, so, from the impedance changes at the detection coil, fabric break is detected.

Inventor: TSUCHIDA HIDEKI
IPC: G03G15/16
Filed: 1989-04-24
Abstract: PURPOSE:To accomplish a compact image forming device which can readily recover toner and never develops transfer irregularity by permitting a separating member to separate a recording sheet from a transfer member in a position in which the recording sheet is attracted to the transfer member to be carried and is almost turned over, and ejecting the sheet with its recording surface facing downward. CONSTITUTION:The transfer member 8 with the surface made of an insulating layer is oppositely arranged on a latent image carrier 4, and is electrified to polarity opposite from toner. The recording sheet 2 is separated from the transfer memory 8 by the separating member 12 in the position in which the recording sheet 2 is attracted to the transfer material 8 to be carried and is almost turned over, and is ejected with its recording surface facing downward. Consequently, the position in which the recording sheet enters the transfer member 8 is nearly vertically overlapped with the position in which the recording sheet is separated therefrom. A toner recovering part 13 and a fixing part 9 are arranged over the transfer member 8, which is arranged close to a fixing device 9. Therefore, the distance that the recording sheet is carried to the fixing device 9 from the transfer member 8 is shortened, thereby making the device compact. Toner is recovered smoothly and transfer irregularity is eliminated.
