Title: Paper sheets weighting device for paper feeding device
Inventor: TAKAHASHI KOJI
IPC: B65H3/48
Filed: 1984-12-25
Abstract: PURPOSE:To prevent occurrence of paper jamming by attaching a weighting member, which touches on the top layer paper sheet, to a supporting member to make the weighting member possible to descent corresponding to decreasing of laminated paper thickness, that is by pressing the paper sheets with a stable force to the bottom face of a container even in case of a few paper sheets. CONSTITUTION:A paper weighting board 16 is touching on the top layer blank form sheet 9 with its self weight just above a perforated belt 22 of a vacuum transport 20, when conveying the blank form sheet 9, and the force adding the weight corresponding to the thickness of the laminated paper sheets 9 and the weight of paper weighting board 16 is applied to the lowest layer paper sheet 9, therefore a force applied to the lowest layer paper sheet does not become zero, and degree of change becomes small compared with the usual, and even if a few sheets are remained after the thickness of laminated paper is decreased, the blank form sheet 9 in a paper set tray 1 is maintained in a stable condition. Accordingly, jamming does not occur owing to the fact that a blank form sheet 9 is caught by the flying manifold 29, or the blank form sheet is not broken, and paper feeding is performed smoothly and securely.

Title: Underground excavator position detecting method and device
Inventor: IWATO MASAHIKO
IPC: E21B47/024
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To measure the position of an underground excavator with high accuracy by forming one optical fiber gyro for detecting a yawing angle into a gimbal gyro, and correcting an error generated by vibration and the like in surrounding environment. SOLUTION: An underground excavator 10 is suspended from a crane of a frame 11 and operated to move vertically by a winch 12, and a drum cutter 13 at the lower end excavates underground. Excavated sludge is discharged to the ground through a sludge pipe 14. The triaxial rotation angle of the excavator 10 is detected by a triaxial accelerometer and a gimbal triaxial optical fiber gyro disposed at the excavator 10 so as to detect a yawing angle. A computer inputs this information along with the depth data of a depth indicator, computes and measures the absolute value (depth, driving direction, and the like) of the excavator 10 during excavating work continuously and automatically.  At this time, drift is generated to the gyro due to distrubance of sound, vibration, and the like, but the excavator 10 is put in a temporarily stationary state to correct drift at the time of stopping driving for the extension of the pipe 14. Measurement of high accuracy can thereby be performed.

Title: Electric hot water heater
Inventor: HAYASHI TAKEHIKO
IPC: F24H9/00
Filed: 1988-10-31
Abstract: PURPOSE:To produce an electric heater for hot water which is structurally resistant to crevice corrosions by placing a packing for a welded heater port at a position not in the deposition metal zone, not affected by weld heat, and free from influences of oxide scales resulting from welding and by placing the packing out of contact with an R-curved shape part. CONSTITUTION:An electric heater for hot water has a tank formed of a shell plate 1, upper end plate 2, and lower end plate 3, assembled by welding, and is equipped at a lower side position of the shell plate 1 with an electric heater 4, which is attached to a heater port 5 with a packing 6 interposed therebetween. To avoid influences of welds, it is avoided for the packing 6 to be put in contact with oxide scales and weld heat-affected part so that formation of crevices between the deposited metal zone and the packing 6 is prevented. The work deformation part of the heater port 5 is also avoided so that the structure is free of minor crevices that may form between the packing 6 and the deformation part of the heater port 5. When a thin packing 6 is used, the contact end of the packing 6 on the side of the water is approximately aligned with an R-curved part of the heater port 5. Thus factors furthering crevice corrosions resulting from welding at the place of contact of a packing are eliminated; crevice corrosions are also prevented by preclusion of spaces at the place of contact of a packing.
