Title: Reluctance motor
Inventor: INOUE MASAYA
IPC: H02K19/10
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To solve the problems of a reluctance motor where the strength at a slit bridge part is deficient in a large machine or a high-speed machine, employing a multilayer slit structure for enhancing efficiency and power factor, and that compatibility between centrifugal resistance and efficiency/power factor is difficulty to attain because magnetic leakage path formed, when the outer circumferential part is reinforced in order to ensure centrifugal strength to cause lowering of the efficiency/power factor. SOLUTION: The reluctance motor has a structure where the rotor is made of magnetic steel plates laminated in multilayer slit structure, the strength member having slit shape of different thickness at the slit bridge part is clamped in the laminating direction of magnetic steel plated, and the strength member is provided with a hole at a position, where the slit shape is shared with other magnetic steel plate. When molten metal is die cast, the molten metal penetrates the slit part, and at the same time, an end ring is formed at the shaft end through die casting. Since each magnetic steel plate is supported by solidified end ring and strength member after the molten metal has solidified, a sufficient centrifugal resistance can be ensured, even for a high speed or large-sized rotating machine.  Furthermore, it functions as a synchronous induction reluctance motor can be attained, because the molten metal forms axial conductors and the end ring.

IPC: F25B9/02
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a Joule-Thomson type cooler having a small temperature change of an object to be cooled. SOLUTION: An expansion space for generating a cold by expanding a refrigerant gas is demarcated. The gas flows from one end of an inlet passage into the passage. Micropores are connected to the other end of the passage. The gas flowing to the passage is ejected into the space through the micropores.
