Abstract: PURPOSE:To attain high speed thermomagnetic recording by using a flat coil as a magnet to impress a magnetic field in the film thickness direction of a medium and using this flat coil also as a Fresnel ring band to condense parallel rays on one point. CONSTITUTION:A magneto-optical recording head is composed of an objective lens part 1 which unites an objective lens 6 and a focus tracking coil and a substrate part 2, etc., to load a light source, a photo-detecting element and a spectral optical system. The objective lens 6 is composed of a transparent substrate 11, a lens supporting part 12 and a flat coil 21 to be constituted of a superconducting material. The flat coil 21 has special arrangement and structure to be used also as the optical system and the coil 21 is composed of the plural ring bands to be arranged in a concentric circle shape. Then, the respective ring bands are set so that a radius and a line width can be in the shape of the Fresnel ring band. Thus, since an optical lens system and a magnet system are merged, light projection and magnetic field impression are executed from a same direction and the generating position of the maximum magnetic field and the focus of the light can be made coincident. Then, the head can be used suitably for high speed seek and high speed recording.

Filed: 1988-02-09
Abstract: PURPOSE:To minimize the reduction of a reception level by arranging a 1st antenna and a 2nd antenna applied to the diversity reception at an interval V in the perpendicular direction and at an interval H in the horizontal direction. CONSTITUTION:The antennas 1, 2 are arranged at an interval V in the perpendicular direction and at the interval H in the horizontal direction. In the case of propagation of line-of-sight, the reduction in the reception input level caused due to a phase difference between a reflected wave on sea and a direct wave is minimized by selecting two reception signals obtained from the two antennas 1, 2 placed in the vertical position (interval V) being an odd number of multiple of a half pitch of a height pattern. In the case of propagation of over the horizon, the reduction in the reception input level is minimized by selecting two reception signals of a different propagation path obtained from the two antennas 1, 2 placed in the horizontal position (interval H). Thus, the diversity reception corresponding to the propagation of line-of-sight and over the horizon is obtained in the microwave communication line having such two propagation states.

Abstract: PURPOSE:To enable a further increased force greater than the sum of the forces of both engines to be produced, by dividing the gasoline engine or the Diesel engine of an automobile, or the like into two parts, and by arranging them horizontally respectively so as to have the same electrical position. CONSTITUTION:While the conventional engine transmits force directly to the crankshaft via a piston, in this horizontally operating engine, the engine is divided into two parts, for instance, in an engine of cubic capacity of 100 cc, this is divided into two pistons having the half of the cubic capacity or 55 cc, and these are arranged horizontally so as to have the same electrical position, so that both pistons are opposed to strike against each other at the same time, and in such a case, while an impact force greater than the sum of the forces of both engines further as much as 10% to 15% is caused, the force is transmitted to a shaft or the like via the crankshaft so as not to miss the impact force. In the case of two-cylinder, three-cylinder, or four-cylinder engines, according to the above procedure, it will suffice to divide them into four, six, or eight piston engines respectively.

Title: Water cleaner of low-voltage impression type
Inventor: OIKAWA YUKIO
IPC: A61L2/02
Filed: 1989-02-06
Abstract: PURPOSE:To prolong the life of batteries and to decrease the frequency of battery exchanges by using the batteries as a power source and providing a switching means which switches the energization and non-energization of a positive electrode and a negative electrode. CONSTITUTION:A positive electrode 16 and a negative electrode 17 are electrically connected to a 1st battery 7 and a 2nd battery 8 for a prescribed period of time (for example, 1 second) by the operation of a switching means 44 when the cock of a faucet connected to the water cleaner is operated. The energization of the positive electrode 16 and the negative electrode 17 is stopped by the operation of the switching means 44 after about one second. A counter electromotive force is then generated between the positive electrode 16 and the negative electrode 17. The propagation of the microorganism in a filter 4 is, therefore, suppressed by the counter electromotive force even if the positive electrode 16 and the negative electrode 17 are not energized while the water cleaner is not in use as a user closes the cock of the faucet. The 1st battery 7 and the 2nd battery 9 are consumed only for the first one second when the water cleaner is used in such a manner and, therefore, the life of the batteries is prolonged.
