Title: Vehicle azimuth detector
Inventor: KATO TAKAHIRO
IPC: G01C17/38
Filed: 1991-09-10
Abstract: PURPOSE:To detect an accurate azimuth by subtracting the output signal of an integration means from the azimuth signal of an earth magnetism sensor and attenuating the obtained difference signal to add the same to the angular velocity signal of an angular velocity sensor to supply the added signal to the integration means. CONSTITUTION:An earth magnetism azimuth operation circuit 3 operates an earth magnetism azimuth signal thetar from the X- and Y-component signals outputted from an earth magnetism sensor 1. A subtractor 4 is connected to the operation circuit 3 to calculates the difference signal of the signal thetar and the signal processed from an integrator 5. An attenuator 6 is connected to the subtractor 4. The output signal from the attenuator 6 and the angular velocity signal omega being the output signal of an angular velocity sensor 2 are supplied to an adder 7 and added by the adder 7 to be outputted. The integrator 5 integrates the signal outputted from the adder 7 to output the same as a detection azimuth signal theta. When a vehicle goes straight on, the signal theta is converged into the signal thetar. When the azimuth of the vehicle is changed, the low-band component of the signal 6 is determined on the basis of the signal thetar and the high-band component thereof is determined on the basis of the angle obtained by integrating the signal omega.

Title: Gusseted diaphragm type ink-jet head
Inventor: INUI TETSUYA
IPC: B41J2/045
Filed: 1994-09-27
Abstract: PURPOSE: To obtain an ink-jet head showing a high degree of integration and high discharging efficiency by fixing a peripheral edge part of a buckling body having a gusseted part arranged on radiating lines on the upper surface thereof, inducing a buckling deformation at a central part of the body by heating and producing a discharging pressure for discharging ink. CONSTITUTION: When the ink-jet head is to be operated, ink is filled in a gap 3 and a cavity 9 beforehand. A current is then supplied to a heater layer 6 and Joule's heat is generated to expand a buckling body 2. However, since a peripheral edge part 4 of the buckling body 2 is fixed to a substrate 1, the buckling body can not expand. As a result, a compression pressure is generated in a radial direction inside the buckling body 2. If the current is continuously supplied to heat the body until the compression stress exceeds a certain value, the buckling body 2 buckles and is deformed into the shape like a dome in a perpendicular direction to the substrate 1. At this time, a frilled part absorbs and eases the compression stress in an inner peripheral direction, so that the buckling is easy to take place.  The pressure of the cavity 9 is raised due to a change in volume subsequent to the buckling, and the ink is discharged and printed from a nozzle 12. When the current is shut, the temperature is decreased and the buckling body is recovered from the buckling to the original state.

Title: Geodesic lens and its production
Inventor: TAKADO NOBUKAZU
IPC: G02B6/122
Filed: 1985-10-16
Abstract: PURPOSE:To correct aberrations by adjusting partially the quantity of ultraviolet rays or light irradiated to a thin film consisting of an arsenic sulfide if the shape of a recess is deviated from a design and aberrations occur in a geodesic lens. CONSTITUTION:If the center of the recess is deeper than the design, the refractive index of an optical waveguide 7 consisting of an arsenic sulfide provided on the recess is raised gradually in the direction vertical to the propagation direction of a guided light according as going away from the optical axis, but is uniform in the propagation direction of the incident guided light. Consequently, since the part along the optical axis in the waveguide in the recess has the lowest equivalent refractive index if the depth of the recess 3 is deeper than the design and the optical path length of the beam propagated is most deviated from the design value, the propagation speed of the beam passing the optical axis is high to cancel the phase difference due to the extension of the optical path length, thus obtaining the geodesic lens having no aberrations.
