Title: Manufacture of r-t-b anisotropic bond magnet
Inventor: IKEGAMI TAKASHI
IPC: B22F9/04
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain an R-T-B anisotropic bond magnet showing an excellent square demagnetization curve by improving the secular change of the magnetic characteristic in a method for manufacturing the magnet by hydrogenation and recrystallization. SOLUTION: When an R-T-B alloy ingot is directly hydrogenated and recrystallized, the shape of the ingot changes before and after the ingot is treated by a hydrogen occluding disintegration method while the temperature of the alloy rises, because the temperature of the ingot is raised in a hydrogen atmosphere.  However, when the alloy powder obtained by the disintegration method is molded after the powder is kneaded with an inorganic binder and the molded body is hydrogenated and recrystallized, the secular change of the magnetic characteristic of the molded body is improved as compared with the conventional example and, when alloy powder which is not subjected to the hydrogenation and recrystallization and has an extremely weak coercive force is molded in a magnetic field, the molded body has a high degree of orientation as compared with a molded body obtained by molding powder which is not subjected to the hydrogenation and recrystalliztion and has a high coercive force in a magnetic field. Therefore, when the molded body is hydrogenated and recrystallized, an R-T-B anisotropic bond magnet showing a square demagnetization curve much better than that of the conventional example can be manufactured, because the excellent degree of orientation which is given to the molded body before the treatment does not change.

Since the tip section sides of the pins 4 are inserted into the pipes 12, the tip surfaces of the pins 4 are never disconnected from the electrodes 23 of the chip 2. In addition, the pins 4 are constrained to the inner surface of the pipe and are prevented of excessive flexing, and a high elastic deformation stress can be obtained.

Abstract: PURPOSE:To facilitate the removal of resin burrs adhered to the sides of external leads by a method wherein resin burr removing mold is shifted to the direction moving from the side, on which the burrs of respective leads are developed, to its opposite side under the condition that the first and the second leads are arranged so as to direct the burrs, which are developed at the edges of the first and the second leads by blanking, to the same direction. CONSTITUTION:Under the condition that a punching die 18 is on stand by upward, an element-lead frame assembly 7 is set on a seating stand 19 so that lead parts 1a and 2a locate above a first seating part 17a, a resin encapsulant 8 locates above a second seating part 17b, resin burrs 16 locate above a hole 17c and the top face (or the side, on which burrs are produced,) of the assembly 7 faces to the punching die 18 side. In succession, the punching die 18 is moved downwards until the die fits to the hole 17c of the seating stand 17. Thus, resin burrs 16 formed between the lead parts 1a and 2a and the resin encapsulant 8 are pushed by the punching die 18 off the lead parts 1a and 2a and the resin encapsulant 8. Thus, since the resin burrs 16 are stricken from the main surface side, on which the burrs of the lead parts 1a and 2a are developed, the resin burrs can be easily removed.

Title: Fault locator
Inventor: HONDA YUKIO
IPC: G01R31/08
Filed: 1992-12-21
Abstract: PURPOSE:To eliminate the dead time of the locator by a method wherein, even when data transfer is started by induction surge outside a location section, a separate storage means is set to a writable state before the data transfer is started. CONSTITUTION:A surge current is compared with a definite level in a surge detection circuit 3A. When the definite level is exceeded, a surge detection pulse signal is generated and supplied to a trigger generation circuit 5A. The circuit 5A delays the supplied surge detection pulse signal by a definite time. When the pulse signal is supplied to a control circuit 10A, the circuit 10A allows a memory next to the memory in a present write state inside a waveform storage device 6A to be set to a writable state. Thereby, the waveform of a surge current generated by the next fault can be stored. In this manner, at least one memory inside the device 6A is always set to a writable state, and a surge current generated by a fault inside a location section can be stored even after an induction surge has been generated from the location section.
