Title: Production of electric welded stainless steel pipe
Inventor: NISHIDA YASUO
IPC: B23K13/00
Filed: 1989-07-28
Abstract: PURPOSE:To prevent the lowering of the product appearance and the workability of the electric welded stainless steel pipe by producing the electric welded steel pipe in at least two stages; a stage for lightly cutting the beads on the outside surface of the weld zone at the bead temp. above a specific temp. and a stage for lightly cutting the same at the bead temp. below the specific temp. CONSTITUTION:A 1st cutting tool 3, a bead part cooler 4 and further a 2nd cutting tool 5 are disposed along the weld zone W on the downstream of squeezing rolls 2 for press welding the weld zone W of the electric welded steel pipe 1. The beads are lightly cut by the 1st cutting tool 3 and thereafter the pipe is cooled to <=500 deg.C by the bead cooler 4 as the 1st stage. The beads on the outside surface are lightly cut by using the 2nd cutting tool 5 as the 2nd stage. The reason for limiting the bead temp. lies in that the cutting resistance is large if the bead temp. is below 500 deg.C and, therefore clattering arises or the chipping of the cutting tool is liable to arise in the 1st stage. A hardened layer is generated in the cut part if the beads are cut at >=500 deg.C in the 2nd stage and, therefore, the hardened layer is removed by maintaining the bead temp. at <=500 deg.C.

Title: Drum type washing machine
Inventor: MATSUMOTO TAKESHI
IPC: D06F49/02
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To predict the vibration at high speed dewatering to correct the deviation of objects to be washed at large vibration by providing a means for judging the magnitude of vibration at a predetermined low speed rotation, at which vibration nearly proportional to the vibration at high speed rotation can be obtained, and a means for correcting the deviation of objects to be washed. SOLUTION: A vibration sensor 20 is attached to a water tank to sense horizontal or vertical components of rotation directions of a drum to input a signal sensed by the sensor into a CPU 100 via a rotation number sensing circuit 104. In a dewatering process, the drum is normally rotated at a low speed and when vibration at a predetermined low rotation number correlative with vibration at high rotation exceeds a predetermined vibration value A, acceleration is continued. When vibration exceeds the value A, the drum 3 is stopped and rotated reversely to correct the deviation of objects to be washed and thereafter when vibration falls below the value A, the drum is accelerated to effect dewatering. In the whole process, when the vibration exceeds a vibration value B (>A), the drum is immediately stopped to correct the deviation of the objects.

Title: Reducing method of earth pressure working to box culvert
Inventor: NAKAGAWA YOSHIHIRO
IPC: E03F3/04
Filed: 1992-06-12
Abstract: PURPOSE:To reduce working earth pressure, to shrink the cross section of a member and to diminish the quantity of a reinforcement used by arranging a material shrunk by the pressing of foamed styrene, etc., onto the top block of a box culvert so that a peripheral line is formed in an arch shape. CONSTITUTION:A Shrinking material 5 such as foamed styrene is disposed onto the top block 1 of a box culvert so that a peripheral line 6 is formed in an arch shape. When the box culvert is banked, the shrinking material 5 is compressed by the working of earth pressure, and soil is displaced while following up the displacement of the peripheral line 6 of the shrinking material 5. Strain in the circumferential direction of the peripheral line 6 of soil in the vicinity of the shrinking material 5 is increased by the displacement, and stress in the same direction is augmented. Component force in the direction of the radius of curvature of the peripheral line 6 of the increased stress resists stress in the same direction, and main stress flows in the arch shape. Consequently, earth pressure working to the culvert does not increase much even when a soil covering section is augmented. Accordingly, the cost of construction can be economized.
