Title: Level shifting circuit
Inventor: KIMURA TOSHIO
IPC: H03K19/00
Filed: 1984-04-20
Abstract: PURPOSE:To make high-speed switching possible by connecting an MOSFET, where the source has the second potential, and an MOSFET having the same polarity as said MOSFET in parallel. CONSTITUTION:An MOSFETM4 where the source has a power source potential V2 is operated as a load of an FETM3. An FETM5 is connected in parallel to the FETM4. When an output node (b) is switched from the power source potential V2 to a potential b', the load capacity is charged with a difference I2-I1 between current capabilities of FETs M3 and M5. When the node (b) is switched from the potential b' to the potential V2, the load capacity is charged with the current capability I1 of the FETM5. Consequently, the time when the output node (b) is changed from the potential b' to the potential V2 is determined by the current I1. That is, the rise time and the fall time of the output node (b) are shortened and are made equal to each other if I2-2.I1 is true.

Title: Thin magnetic film having high permeability and excellent frequency characteristics
Inventor: TERASAKA SHOJI
IPC: H01F17/04
Filed: 1990-03-30
Abstract: PURPOSE:To provide a thin ferromagnetic film with a high permeability without applying thermal treatment after formation of the film and to maintain this magnetic characteristic up to a high frequency area by splitting the film into strips at the angle in specified range from an easy magnetization direction of the film. CONSTITUTION:A ferromagnetic thin film is splitted into strips at an angle within 10 to 70 degrees from an easy magnetization direction of the film. The splitting direction is at the angle of theta with the easy magnetization direction. If theta ranges from 10 to 70 degrees, a permeability increases in a high frequency area. It is preferable to make the angle range from 20 to 50 degrees. If theta is less than 10 degrees or larger than 70 degrees, a frequency characteristic of permeability is almost same at that of the conventional thin magnetic film and there is very small improvement in characteristics. If the stripped thin magnetic film is split in the mm order, there is some improvement in characteristics. When the splitting width is larger than 5mm, however, the improvement in characteristics gets smaller and smaller. Then, the maximum splitting width is 5mm. As the strip width gets narrower, a resonance frequency increases. With the strip width smaller than 5mum, a sudden drop in permeability is caused. Then, the lower limit is 5mum.

Abstract: PURPOSE:To form a circular ring without causing buckling by applying axial compressive force to a material ring, thrusting an outer roll that can move independently in radial direction divided to plural number against outer periphery of the material ring, and forming a concavity while rotating the material ring. CONSTITUTION:A material ring 21 is pressure held between inner rolls 30, 31 and expanded, and the ring is rotated while applying large compressive force to the upper part of the ring 21 by tilting the inner rolls 30, 31 by the action of cylinders 35, 36. Pressed position of the ring 21 is changed to circumferential direction by a cylinder 39. An outer roll 10 is pressed down and both end parts of the ring are pressed by flange part forming rolls 12, 13. Then, an eccentric shaft 14 is rotated by the action of a cylinder 29, and a drop part forming roll 11 is pressed down relatively against flange part forming rolls 12, 13. At this time, the drop part forming roll of inner rolls 30, 31 keeps the gap to the drop part forming roll 11 of outer roll 10 automatically in the thickness of the material ring by deformation of an elastic member 42. Thus, no reduction of thickness of the material ring 21 is caused.
