Inventor: MURAKAMI MASAHITO
IPC: H01F6/06
Filed: 1993-10-13
Abstract: PURPOSE:To easily control a generated magnetic field by providing a composite magnet composed of a core made of an R-Ba-Cu-O bulk superconducting material manufactured by a melting method and a normal conducting or superconducting coil surrounding the core. CONSTITUTION:A superconducting bulk body 1 is obtained from an R-Ba-Cu-O superconducting material, with the R being composed of one or more tare-earth elements selected from among Y, Sm, Eu, Gd, Dy, Ho, and Er by using a melting method. A composite magnet is formed by winding a superconducting copper coil 2a which can make an electric current of 10A in maximum to flow around the bulk body 1 by 100 turns. When an electric current of 5A is made to flow to the coil 2a, a 1-kG magnetic field is generated at the central part of the bulk body 1 and, when an electric current is made to flow in the opposite direction, the magnetic field of the bulk body 1 gradually becomes weaker and the outer periphery of the magnetic field becomes zero at 5A. Therefore, the magnetic field of the bulk body 1 can be changed.

Title: Method and device for manufacturing tube, inside of which is smoothed and outside of which has rib, from extrusion moldable plastic
Inventor: HORUSUTO RAAN
IPC: B29C48/35
Filed: 1988-11-04
Abstract: PURPOSE: To conduct an introduction of a molten material to a recess of a mold channel and a delay formation of a ribbed tube by the molten material at the time of accompanying with the introduction at least at a predetermined part of an outer periphery by forming a suitable protrusion at a desired part of delay discharge at an end face of a piston directed toward an extruder, and obtaining a narrow part. CONSTITUTION: A nozzle channel 9 is broadened in a flared state immediately before a discharge port opened at a mold cavity disposed between a nozzle jacket 7, a movable mold 3 and a piston 10. Since an end of the piston 10 substantially has a radially curved surface at an outside, a molten flow is discharged at this spot while having at least a radially curved surface state. Since extrusion molding openings at two regions disposed at a molten end and a base are narrowed, a velocity of plastic flowing into a groove 20 provided at a wall of the channel is faster at the introducing velocity to the upper end and the base than an introducing velocity to the part of a rib cavity 20 disposed at right and left sides. First, the plastic is filled in the rib cavities of the upper end and the base, the air is discharged to a connecting part 21. Hence, sufficient introduction is ensured.

Title: Positioning device of small sized printer
Inventor: IMAMURA KAZUMORI
IPC: B41J29/10
Filed: 1987-11-06
Abstract: PURPOSE:To reduce the impact noise of a positioning board and a ratchet, by establishing an injection part of a cushioning material to a positioning board fixing part of a positioning device to be engaged with a ratchet positioning board arranged on an outer peripheral surface of a drum. CONSTITUTION:When a drum 1 is rotated in the arrow A direction, a top part 301 of a positioning board 3 is moved in the arrow c direction and is brought into a state where a crest part 102 of a ratchet comes in contact with the top part 301. When the drum 1 is further rotated in the arrow A direction, the top part 301 is detached from the crest part 102 and is moved in the arrow D direction to collide with a ratchet slant part 103.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for revising a circuit whenever the number of horizontal dots of a display input signal are revised by displaying the display signal of the number of optional horizontal dots within the range of row memory capacity. SOLUTION: When a display timing signal 3 becomes a 'low' level, a count means 32 stops count-up operation, and a horizontal display dot number latch means 34 latches the number of horizontal display dots 33 when a rise of a horizontal synchronizing signal 4 is inputted, and outputs the number of latch horizontal display dots 35 to a comparison means 36 until the rise of the next horizontal synchronizing signal 4 is inputted, that is, for the period displaying the output data 20. When a read-out address 17 is equalized with the number of latch horizontal display dots 35, the latch horizontal display dots 35 and the read-out address 17 become equal, and the comparison means 36 outputs a low level signal to a comparison output 37 to reset a read-out address generation means 28. Thus, the read-out of three times or above are performed from a RAM 7 for one horizontal period.

IPC: B23K20/00
Filed: 1994-11-15
Abstract: PURPOSE: To heighten the absorbed energy in the fracture. CONSTITUTION: In the case of working a joint consisting of different materials having the brittle bonding interface whose impact value is small, the bonding interface 3 is worked in the direction orthogonal thereto, and the bonding interface is bent toward the base metal side by >=15μm to heighten the absorbed energy in the fracture. In the joint consisting of different materials in which the brittle reactive layer is generated at the bonding interface 3, the crack is linearly generated along the bonding interface 3 to deteriorate the absorbed energy in the fracture when the impact load is applied to the bonding interface 3.  However, if the plastic flow of the upper exposed part of the bonding interface 3 is made in the direction of the base metal which is excellent in the impact performance and toughness by the machining, the crack in the impact fracture is generated in the upper exposed part of the bonding interface 3. Then, the crack is propagated in the base metal excellent in the impact performance, and the absorbed energy in the fracture is heightened.
