Abstract: PURPOSE:To branch or combine two orthogonal polarized electromagnetic waves simultaneously by arranging a conductor plate having plural slits in parallel with a reflecting face with an angle of nearly 45 deg. provided to a T-shaped branch part and selecting the slits to be directed in a direction orthogonal to one of the two polarized waves. CONSTITUTION:A triangular prism shaped reflecting face 2 is provided to a T-shaped branch of a square waveguide 1 with an angle of nearly 45 deg. with respect to the propagating direction of an electromagnetic wave. A conductor plate 3 is arranged in parallel with the reflecting face 2: Plural slits S are formed in a direction perpendicular to the electric field of a TE01 wave to the conductor plate 3. Thus, the TE01 wave passes through the conductor plate 3. On the other hand, since the TE10 wave has an electric field in the same direction as the slits S, the wave is effected by the conductor plate 3. Then the reflecting face 2 is designed to provide the propagation characteristic suitable for the TE01 wave and the position of the conductor plate 3 in parallel with the reflecting face 2 is designed to provide the propagation characteristic suitable for the TE10 wave. As a result, the excellent propagation characteristic is obtained to both the TE01 wave and the TE10 wave.

Title: Abnormal temperature controller for room heater
Inventor: TAKAHASHI SADAMITSU
IPC: H05B3/00
Filed: 1991-11-25
Abstract: PURPOSE:To secure the safety by stopping supply of power to a heat generator if a sensed temperature signal from a temperature sensor becomes a temperature set reference signal or more. CONSTITUTION:A comparator 18 compares a temperature signal Vd responsive to a sensed temperature of a temperature sensor 13 with a set temperature signal Vset of a temperature setter 16, and a controller 17 controls a normal power supply amount to heat generators 6, 7 in response to its temperature difference. Here, if a temperature of a room heater body locally rises to become an abnormal temperature of a predetermined value or higher (e.g. 80-120 deg.C), i.e., if the signal Vd of the sensor 13 becomes the reference signal or more, the controller 17 receives the temperature difference from the comparator 18, and stops supplying power to the generators 6, 7. Thus the safety can be secured.
