Title: Propeller
Inventor: MARUYAMA NAOTO
IPC: B63H1/02
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a propeller capable of increasing its rotation efficiency and opposing to a stream properly. SOLUTION: This propeller is formed into a spindle shape like an American football ball to collect streams spreading at the back of a screw again in the direction of a rotary shaft of the screw. It is possible because the streams attempt to attach to the propeller to compensate a difference in density of its medium (air and water). Consequently, the streams provide high density and a strong propulsion force. Moreover, a rear half part of the spindle-shaped propeller rotates also along the streams to increase the number of revolutions and make the propeller advance furthermore. As a result, air and water are not lashed up, and the propeller faces the longitudinal direction easily at all times for the streams owing to its spindle shape.

Title: Mobile phone
Inventor: HARUYAMA SHINICHI
IPC: H04W88/02
Filed: 2000-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a mobile phone whose SAR(specific absorption rate) can be distributed. SOLUTION: The mobile phone 10 is provided with 4 very small antennas 20. The very small antennas 20 are used to send/receive the same signal at the same time. When a user uses the mobile phone 10, the transmission power is distributed to the very small antennas 20 so as to distribute the proximity electric field to the head 30 of the user because of the 4 radiation sources. As a result, the SAR can be reduced without weakening a radio wave to a radio base station. That is, the radiation power from each of the very small antennas 20 is 1/4 of the radiated power of one antenna and then the SAR can be reduced to 1/4.
