Inventor: YAMAMOTO AKIRA
IPC: G03B9/00
Filed: 1983-03-11
Abstract: PURPOSE:To prevent the interference with another stopping blade by uniforming the shape and size of all stopping blades and forming a slight bending part on the tip of only one stopping blade to form a totally-enclosed stopping blade.

Title: Reflection transmitter
Inventor: IGA AKIRA
IPC: H04B1/04
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To operate a transmitter without a power suply by changing the impedance of an antenna according to the transmission data, whereby an incident electric wave is modulated to be re-emitted as a reflected wave. SOLUTION: When a transmission wave 11 of a communicator 10 is received, voltage is induced in a dipole antenna 4 and a received electric wave I flows. The received electric wave, that is, the transmission wave 11 is re-emitted from the antenna 4. According to on/off of a transistor 8, the impedance between power feed points 4a, 4b is changed. The reflection characteristic of the antenna 4 depends upon whether a matching is obtained between the antenna 4 and the transmission wave 11 or not. That is, the transistor 8 is turned on/off, thereby phase-modulating the transmission wave 11 and reflecting the same. Accordingly, in the communicator 10, a composite wave of the reflected wave 14 and the transmission wave 11 is received and and phase-modulated to receive the data.  It is not necessary to make a carrier wave, so that it is not necessary to provide a transmission circuit and a power supply for transmission. Further, a receiving circuit and a power supply for receiving are not needed.
