Title: Electromagnetic induction heater
Inventor: HATTA SHINICHIRO
IPC: H05B6/12
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To make a heating container lightweight and reduce cost by separating a ferromagnetic part which causes magnetic flux change from a paramagnetic conductor part which bears eddy current loss. SOLUTION: When an exciting a.c. magnetic field is applied to an insulating substrate 2 containing a ferromagnetic material 1, magnetic flux change is produced in the ferromagnetic material 1, but eddy current does not flow between the ferromagnetic materials 1. When a paramagnetic conductor having the same size as an exciting current circuit is brought into contact with the ferromagnetic material 1, eddy current flows in a paramagnetic conductor, induction heating is produced. Even if ferromagnetic material 1 is not contained in a heating container, by bringing the paramagnetic conductor into contact with a substrate 2, induction heating is produced. By deciding the shape and arrangement of the ferromagnetic material 1 so that the circuit magnetic resistance becomes minimum in a magnetic circuit forming between an exciting yoke, eddy current loss efficiency is enhanced.  The container is made lightweight and low cost without decreasing eddy current loss.

Title: Shake correction device
Inventor: KUDO TOSHIMICHI
IPC: G03B5/00
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent such erroneous action that a shake is amplified because phases are not aligned by controlling a pass band restriction means so that a band equal to or over a prescribed frequency is cut off when a shake frequency equal to or over the prescribed frequency is detected. SOLUTION: By a shake frequency detector 211, a shake frequency component is detected from a signal outputted by a high-pass filter HPF 202. Then, frequency data detected as the largest one is outputted by the detector 211. By a shake state discrimination unit 212, a shake state is discriminated based on the signal outputted by the HPF 202 and the shake frequency data outputted from the detector 211 so as to control the cut-off frequency of an HPF 210. In this case, a mode is switched to one of the correction mode and the still mode by the unit 212. That means, a shake correction band is restricted and the cut-off frequency of the HPF 210 is changed in order to eliminate the shake of a video caused by noise. The cut-off frequency of the HPF is set sufficiently low in the ordinary mode and set to a value required for eliminating the noise in the still mode.
