Title: Manufacturing sintered rare earth magnet
Inventor: KISHIMOTO YOSHIHISA
IPC: B30B11/02
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To produce a sintered rare earth permanent magnet such as R-Fe-B and R-Co types having a thin wall shape or a small size shape and superior magnetic characteristics by suppressing a rare earth element-contained alloy powder from reacting with a binder, reducing the residual O and residual C in the power after sintered, and improving the fluidity and lubrication of the powder at forming to improve the dimensional accuracy and productivity of a molding. SOLUTION: A binder of a polymer with water or organic solvent and binder composed of at least one polymer are added to a rare earth element-contained alloy powder and stirred into a slurry, the slurry is atomized into liq. drops in a chamber of a spray drier and instantaneously dried to harden grains, thus improving the fluidity and lubrication of the powder at compression forming. Before forming, a mechanical vibration is applied to dies to form thereafter, this improving the magnetic field orientation enough to obtain a thin wall shaped or complicated shaped sintered permanent magnet superior in magnetic characteristics.

Title: Driving method for liquid crystal display device for tv receiver
Inventor: TATEISHI KIMIAKI
IPC: H04N5/66
Filed: 1990-06-11
Abstract: PURPOSE:To avoid blur and a sense of incongruity even when a fast moving video image is displayed by selecting a time when a video signal voltage is applied to a liquid crystal display device to be a time shorter than one field time in one frame period and applying a prescribed voltage to the liquid crystal display device for the remaining period. CONSTITUTION:A display signal input selection circuit 17 applies a video signal to a display signal input of an X driver 11 for a period and then applies the video signal to a line 13 sequentially when a control signal EZ1 is at an L level in the timing of displaying a video signal of an odd number field. On the other hand, the selection circuit 17 applies a black level to a display signal input 11 for a period when the EZ1 is at an H level within a vertical blanking period after the video display period thereby applying the black level to the signal line 13. Furthermore, the similar operation to above is implemented even at a timing when a video signal of an even number field is displayed. Thus, video signal periods S1, S2 of odd and even, number fields are not overlapped, then blur and a sense of incongruity are avoided.

IPC: B23K1/00
Filed: 1982-09-03
Abstract: PURPOSE:To obtain a joined cam shaft having improved joining strength, by brazing a shaft member to attachment members after providing different carbon concns. by carburization. CONSTITUTION:A hollow shaft member made of low carbon steel is carburized to increase the amount of carbon in the surface layer of the shaft member and to produce a difference in carbon concn. between the shaft member and attachment members made of low carbon steel such as a cam piece and a journal piece.
