Title: Manufacture of semihard magnetic material, the semihard magnetic material, and magnetic marker formed using it
Inventor: NAKAOKA NORIYUKI
IPC: B22D11/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To obtain the excellent magnetic characteristic of a semihard magnetic material, by laminating alternately layers A whose main bodies are made of Fe having a magnetism and layers B whose main bodies are made of Cu-based nonmagnetic metal to obtain a multilayer body, and by heating thereafter the multilayer body to part it thereafter in the layers B, and further, by subjecting each parted body thereafter to a cold plastic working. SOLUTION: This manufacturing method comprises processes (1), (2), and (3). In the process (1), after laminating alternately metallic plates to be layers A whose main bodies are made of Fe having a magnetism and Cu-based nonmagnetic metallic plates to be layers B, they are joined to each other by a hot hydrostatic pressing or a hot rolling or the combination thereof, etc., or further, by a cold rolling to form a multilayer body. In the process (2), by heating the obtained multilayer body at an adequate temperature, each Cu-based nonmagnetic metallic layer is parted. This processing is called parting processing. This parting processing is performed at a processing temperature of 685-1085 deg.C and in a retention time of 10-180 minutes. In the process (3), each parted body is subjected thereafter to a cold plastic working to obtain a thin plate having a thickness of 0.03-1.0 mm.

Title: Permanent magnet type motor
Inventor: HATTORI MAKOTO
IPC: H02K1/27
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To improve an output by forming an inside of a section of each permanent magnet in an arcuate shape convex toward the rotating center, and forming its outside linear in a semicylindrical state, thereby reducing in size. SOLUTION: A sectional area of each permanent magnet 18 is increased in size as compared with a conventional one. Accordingly, since a value of an interlinkage magnetic flux ϕa on a d-q conversion axis is increased, its magnetic torque is also increased. Further, a magnetic flux at a q axis as a center is decreased at a part passing a rotor core 6, while a part passing the permanent magnet is increased. Since the permeability of the magnet 18 is substantially equal to that of the air, the part of the magnetic flux passing the magnet 18 becomes a magnetic reluctance. Since the d-axis inductance Ld is reduced and the difference between the q-axis inductance and the d-axis inductance Ld is increased, its reluctance torque is also increased. As a result, a rotary torque of a permanent magnet type motor is increased.  If the torque T is the same, a current necessary to drive the permanent magnet type motor is decreased, and hence its copper loss is reduced, and its efficiency is improved.

Title: System for selectively assigning power
Inventor: HOUSTON THEODORE W
IPC: G06F1/32
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in a circuit. SOLUTION: This is a system for selectively assigning a power to the elements of an integrated circuit. A logical part specifies at least one element 36 of the integrated circuit, and selects this element according to a selection signal for saving power consumption. A control interface 38 reduces a power to be consumed by the selected element. This can be achieved by selecting one power source whose voltage is lower from among two power sources, by decreasing clock frequencies, by changing the threshold voltage of a transistor in the element through a voltage adjuster, by selecting one device connected with the lower power supply voltage from among two devices connected in parallel. The logical part can be an instruction handier 30 for confirming whether or not the instruction uses the element, or for processing a power-down instruction to the element.  The element can be an arithmetic logical device, adder, register, or transistor.
