Title: Electric water heater
Inventor: KANBARA MASASHI
IPC: A47J27/21
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To complete the boiling of water by restarting heating after making a determination again as to whether or not an electric water heater is empty, in the event that heating of the water has been stopped due to the error of recognizing the heater to be empty even though the water was being boiled, which may arise in the presence of air bubbles or the convection of hot water during boiling. SOLUTION: When an empty heater detection means 5 detects that the water heater is empty during heating and a heating means 3 is turned off, the temperature is detected by a temperature detection means 4 a predetermined time after the heating means 3 was turned off. If the temperature detected is within a predetermined temperature range with respect to the temperature detected when the heating means is turned off, the heating means 3 is turned on again.

Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an embedded magnet motor of a smaller make and having a higher torque by further suppressing magnetic flux leakage by increasing magnetic resistance between adjacent magnets and improving its magnetic flux passage. SOLUTION: The embedded magnet motor has a rotor 1 and a stator 5.

Non-magnetic part/space 16 is formed, among the plurality of the magnets 8, between both ends of adjacent magnets 8A and 8B facing each other, and the radial width of an outer periphery 15 correspondingly positioned between both ends is narrower than the radial width of the outer periphery positioned to correspond to both ends. The space 16 has a high magnetic resistance.  Diverted from the space by the magnetic resistance, circumferential magnetic flux (a) which passes through the outer periphery 15 correspondingly positioned between both ends is diverted to the radial direction as the cross-section area of the outer periphery 15 is narrowed, so that the magnetic flux leakage formed between the adjacent magnets 8A and 8B is decreased.
