Title: Composite magnetic material
IPC: C22C38/00
Filed: 1992-03-23
Abstract: PURPOSE:To obtain an iron-base magnetic composite material having high magnetic flux density and high-frequency characteristics by mainly comprising iron and arranging a reaction-preventive layer composed mainly of iron or iron alloy between a metallic magnetic alloy and oxide magnetic ferrite. CONSTITUTION:In a composite magnetic material composed of a metallic magnetic alloy 1 and oxide magnetic ferrite 3, the metallic magnet alloy 1 is manufactured by an alloy magnetic material containing iron as a main body. Iron or alloys containing iron as the main body are disposed between the metallic magnet alloys 1 and the oxide magnetic ferrite 3 as reaction preventive layers 2. Consequently, the chemical reaction of the metallic magnetic alloy and oxide magnetic ferrite can be inhibited, and the composite material simultaneously having the high magnetic flux density of the metallic magnetic alloy and the high-frequency characteristics of oxide magnetic ferrite can be synthesized. Accordingly, the composite magnetic material has high saturation magnetic flux density enabling short wavelength recording sufficient for a high coercive force magnetic recording medium and electric resistance. The same characteristics for improving conversion efficiency per volume can be displayed even regarding a switching power supply transformer core.

IPC: G09G3/36
Filed: 1988-03-18
Abstract: PURPOSE:To decrease the currents flowing in at respective potential levels by providing source voltage dividing circuits which specify the potential levels of drivers for display to each of image planes. CONSTITUTION:The respective potential levels of the drivers for display including the scanning electrode driving driver 2 and the signal electrode driving driver 3 are supplied by the two source voltage dividing circuits 4 to the two image planes (upper and lower stage) existing in one liquid crystal display panel 1.

Title: Pinch roll control method
Inventor: TAMAKI HIROSHI
IPC: B23C3/12
Filed: 1986-03-24
Abstract: PURPOSE:To enable substantial energy saving in the pinch roll device of a machining device for a steel strip and the like by controlling a strip feeding electric motor for working as a brake device. CONSTITUTION:A milling cutter 'C' is rotated in the direction of an arrow Ca and a plate 1 is fed in the direction of an arrow Pa for machining. Therefore, a brake device 'B' for a pinch roll PRE is made to work in order that the plate 1 will not be suddenly taken in, when the plate 1 has reached the cutter 'C'. Also, a drive device 'M' needs a drive force exceeding a brake force. In a threading process, plate speed is low and machining reaction is small. Therefore, the brake force of the brake device 'B' is made about a half of a maximum reaction force and the drive device 'M' starts machining with a force slightly over the brake force and a DC electric motor drive controllable in rotation. Thus, the speed of the plate 1 becomes high and the machining reaction force exceeds the brake force of the brake device 'B'. At this point, the control of the drive device 'M' is changed over from drive to control, and a maximum brake force is guaranteed with both of the brake drive 'B' and the drive device 'M'. Consequently, energy is substantially saved.
