    Abstract: PROBLEM TO BE SOLVED: To improve the reliability of the apparatus as a whole by forming a nozzle communicating with a solution storage room by projecting a laser beam on a film member joined to a face of a substrate via the solution storage room obliquely at a predetermined angle. SOLUTION: A nozzle for a diluting liquid 33B is formed on a resin material to which a film member is joined. A nozzle 33A for an ink is formed by an excimer laser irradiation incident on a face of the resin material obliquely at predetermined angle at a normal output level from a face side of a solution room forming member via an ink liquid room and an ink introducing hole. Then by a further excimer laser irradiation of an about double output level, a tip portion 33AZ is formed in the nozzle 33A communicating with a nozzle 33AY for an ink. Ink forced out of the nozzle 33A is discharged along the tip portion 33AZ so as to be mixed with a preferable orientation with respect to the nozzle 33B for a diluting liquid.

    Abstract: PURPOSE:To make it possible to avoid the generation of the hysteresis phenomenon of the oscillation wavelength of a laser beam, which is emitted from a semiconductor laser, to the injection current of the laser by a method wherein a high-frequency current having an amplitude of a prescribed magnitude is made to superpose on the injection current so as to avoid the generation of hte hysteresis phenomenon to the injection current of the laser and is fed to the semiconductor laser. CONSTITUTION:The sum of 100Hz to 100MHz, desirably several tens kHz, of a low-frequency signal, which is generated from a local oscillator 7, and a signal, which is given from a current controlling circuit 9, is converted into a current by a current source 8. An injection current, which is outputted from the source 8, is superposed with 750MHz, for example, of a current by a high-frequency superposing circuit 10 and is fed to a semiconductor laser element 1. Thereby, a high-frequency current having an amplitude of a prescribed magnitude is made to superpose on the injection current of the laser so as to avoid the generation of the hysteresis phenomenon of an oscillation wavelength of a laser beam, which is emitted from the laser, and is made to flow in such a way as to feed to the laser. As a result, the generation of the hysteresis phenomenon of the oscillation wavelength of the laser beam can be avoided.

    Abstract: PURPOSE:To securely generate the polarization inversion of a fine pattern with good controllability by irradiating a ferroelectric material with charged particles to plural areas at intervals which are large enough to exert no mutual influence on each other. CONSTITUTION:The areas on the singly polarized ferroelectric material 1 are irradiated locally with the charged particles to form a polarization inversion structure 3. The areas are irradiate with the charged particles at the intervals LB where no mutual influence is exerted. Thus, interference between adjacent irradiated areas is evaded and polarization inversion 3A can be generated independently. After the areas are irradiated with the charged particles at said intervals LB where no mutual influence is exerted, accumulated charges on the ferroelectric material 1 are removed and other areas nearby the irradiated areas where an electric field is removed are irradiated with charged particles while the intervals LB are maintained to generate each polarization inversion 3A independently.
