Title: Dielectric lens
Inventor: TAKIMOTO YUKIO
IPC: H01Q15/08
Filed: 1992-05-07
Abstract: PURPOSE:To obtain a dielectric lens in which a radiation of radio wave is diffused with respect to an incident radio wave and the radiation radio wave is emitted from an antenna so that reception power intensity on a face with an equal distance from the antenna is uniform by forming a dielectric body to be a concave lens. CONSTITUTION:A curved plane is used for any of an incidence plane S1 and a radiating plane S2 of the dielectric lens 1, and a plane perpendicular to a lens axis A-A is adopted for the other plane. The curved face S2 is formed in such a way that a curvature of the curved plane is increased as a distance from the lens axis A-A increases. As a result, a radiation radio wave by which a reception power intensity Pr on a Q-Q plane with an equal distance from an antenna 4 is uniform is emitted from the radiation plane S2. The shape of the radiation plane S2 of the lens 1 at a position apart from the lens axis A-A by a distance (x) is expressed in equation I, where theta and theta0 are incident and refracted angles of the dielectric body whose dielectric constant is E and Pt is the transmission power strength.

Inventor: MATSUNOBU YUTAKA
IPC: H02K1/27
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To suppress the peak value of induced voltage to an effective value by approximating the waveform of induced voltage to sine wave. SOLUTION: As a permanent magnet 8, an object in such form that the angle θ becomes smaller than the angle ϕ when defined that the angle that the side on stator side, that is, the width of the peripheral face forms to the axis θ and that the angle that the side on anti-stator side, that is, the width of the peripheral face forms to the axis is ϕ is used. Here, the angle θ takes a value in the range of 0<θ<45, because the number of poles of the permanent magnet is eight. Then, using a permanent magnet 8 where the angle θ is 26 deg. and the angle ϕ is 36 deg. as a result of computation will bring the waveform of induced voltage close to sine wave. Hereby, design of the permanent magnet rotating electric machine which can gets maximum drive torque while suppressing the peak value of induced voltage becomes possible.

Title: Magnetic scale device
Inventor: MIBU KATSUTOSHI
IPC: G01B7/00
Filed: 1985-06-28
Abstract: PURPOSE:To prevent the influence of the leak magnetic fields from a magnetic medium for auxiliary signal tracks on magnetic grating signals by recording the magnetic grating signals for a scale to a magnetic medium for main signal tracks and recording the gate signals for the origin to the magnetic medium for the auxiliary signal tracks. CONSTITUTION:Guard bands B1-B4 are formed between the tracks quadrisected in the peripheral direction of the magnetic scale 1 consisting of a rod-shaped magnetic material. The magnetic grating signals for the scale are recorded to the main signal tracks MS1, MS2 which are related to face each other. The 1st and 2nd gate signals for the origin are recorded to the prescribed positions of the auxiliary signal tracks G1, G2. However, both gate signals have the magnetization patterns which are different in polarity from each other and are equal in magnetization intensity. The gate signal magnetic fields are therefore negated with each other even if said magnetic fields leak from the auxiliary signal tracks G1, G2 in the stage of detecting the magnetic grating signal by the main signal tracks MS1, MS2. The ill effect of such magnetic fields on the magnetic grating signals is thus obviated and the origin and scale signals are detected with high accuracy.
