Title: Ink jet recording head
Inventor: SAITO ASAO
IPC: B41J2/05
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To achieve high image quality of a recorded image by a method wherein when an electro-thermo transducing element for small liquid drop is driven, a bubble grown by heating is communicated to the open air, and when a electro-thermo transducing element for large liquid drop is driven, the bubble grown by heating is not allowed to communicate to the open air. SOLUTION: Electro-thermo transducing elements 2, 3 are arranged in parallel by changing a distance L from a nozzle opening to an arranged position in a nozzle 1 of an ink jet recording head. Then, in the case where a small liquid drop is discharged, a bubble owing to film boiling is generated on the electro- thermo transducing element 2 by charging electrically the electro-thermo transducing element 2 to heat suddenly ink near the electro-thermo transducing element 2. The bubble is expanded to be grown to a discharge opening side of small inertia resistance, and allowed to communicate to the open air. Besides, in the case where a large liquid drop is discharged, though the electro-thermo transducing element 3 is electrically charged, the bubble is not communicated to the open air even though the bubble is grown to the maximum one, and a discharge amount of the ink is increased.  Thereby, high image quality of a recorded image can be obtained.

Title: Solid-state laser oscillator and laser marker
Inventor: SASAKI RYOICHI
IPC: H01S3/11
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To shorten the optical path effectively and to reduce the size and weight by providing an optical member for bending the optical path of an induced emission light, between a laser chamber and a Q switch. SOLUTION: An optical path for an induced emission light to be emitted from a mirror holder 60 becomes a path which folds back in the reverse direction an induced emission light emitted from a laser chamber 2, at a position shifted in the directions of the height and width of a base 1, and on this folded back optical path a total reflection mirror 4 and a Q switch 7 are arranged. And the optical path of the induced emission light going and returning between an output mirror 3 and the total reflection mirror 4 is bent by bending mirrors 6, 6 arranged between the laser chamber 2 and the Q switch 7, and it becomes possible to shorten the longitudinal dimension L of the base 1.  Moreover, it becomes possible to reduce the width dimension W of the base 1, since the laser chamber 2 and the Q switch 7 arranged on both sides of this folded back position are arranged at positions different in the upward and downward directions.

Title: Production of magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/85
Filed: 1990-10-11
Abstract: PURPOSE:To improve the wide band C/N of a vertical magnetic recording medium and to improve a film-forming speed by irradiating the film with a beam for heating the electronic beam along a line connecting the center of the formed film and the center of an evaporation source at the time of forming the vertical magnetized film. CONSTITUTION:At the time of forming the film within the range of degrees from 40 degrees of an incident angle, irradiation is executed for heating the electronic beam along the straight line connecting the center of the evaporation source and that of the formed film. Since vapor deposition speed within a vapor deposition range can be made maximum and the mutual operation of a vapor flow and the electronic beam becomes maximum in such a case, the structure of columnar particulates becomes minute and vertically magnetized structure can be realized with high saturated magnetic flux density. Thus, a characteristic from a low band to a high frequency band can be improved.
