摘要： PROBLEM TO BE SOLVED: To provide an ionized alkaline water generator with a cooling function which electrolyzes tap water into acidic water and alkaline water, stores cold water in order to discharge cold acidic water and alkaline water, is equipped with a large-sized cooling unit and is capable of solving the problem of germ proliferation and size expansion of the generator.
SOLUTION: A cold storing agent 2 is preliminarily cooled for cooling the alkaline water discharged from an electrolytic cell 1. When the agent 2 is cooled preliminarily, the cooling capacity of a cooling element 3 is made lower by decreasing power supply, and the element 3 is cooled by a cooling fan 5. When the alkaline water is required, the alkaline water is cooled by the preliminarily cooled agent 2 and the element 3 whose cooling capacity is made higher by increasing power supply. The heat energy radiated from the element 3 is given to the acid water to be discharged separately. As a result, the cooling efficiency of this generator is improved and its size is made compact.

摘要： PROBLEM TO BE SOLVED: To obtain an optimum light spot for different substrate thickness without using an exclusive objective lens by rotating a plane of polarization with a λ/2 half wavelength plate push-pull mechanism, suppressing the occurrence of spherical aberration and further converging an image forming spot. SOLUTION: The light irradiates an optical disk substrate 31 with double substrate thickness instead of a thin optical disk 25 from an objective lens 24 to a recording surface 26. However, in such a case, since the substrate thickness don't coincide with each other, the luminous flux isn't converged to a minimum spot size on the recording surface 26. At this time, a polarizing film 32 is formed on a peripheral part in the effective size of the objective lens 24, and the luminous flux of the peripheral part is interrupted for incident light having an oscillation surface of a right angle, and the occurrence of the spherical aberration is suppressed, and the image forming spot is further converged. Further, the plane of polarization of the incident light is switched by the λ/2 half wavelength plate push-pull mechanism 36. The mechanism 36 is constituted so that an iron core of a maglatch 29 is assembled with a guide arm integrated with a λ/2 half wavelength plate 35, and an opposite pulse voltage is applied to the maglatch 29, and the plane of polarization is rotated.

SOLUTION: A luminous flux which is radiated from a semiconductor laser 21 is converted into a nearly parallel luminous flux by a collimating lens 22, it is transmitted through a returned-light separation prism 23, it is passed further through an objective lens 24, and its image is formed as a very small light spot on a recording face 26 at the bottom face of a thin high-density optical disk substrate 25. In addition, reflected light which is reflected here and which contains information is converted into nearly parallel light by the objective lens 24. In addition, the light which is separated from a forward passage clue to the action of a light separation face 27 formed at the inside of the returned- light separation prism 23 is passed through a condensing lens 28 and a cylindrical lens 29, and it is incident on a light detection part 30 while it is being converged. Then, it is photoelectrically converted so as to be sent to a signal processing part.

摘要： PROBLEM TO BE SOLVED: To enable recording/reproducing an optical disk having a different recording density, to make a device small in size and to improve the reliability by moving an aperture arranged in an optical path and changing a numerical aperture of an objective lens. SOLUTION: When an optical disk 14 of low density is recorded/ reproduced, a light beam from a semiconductor laser 12 is passed through an aperture 2a and made incident on an objective lens 13. At this time, the aperture 2a is arranged so that the numerical aperture of the lens 13 becomes 0.45. The lens 13 forms a spot 17 on the recording surface of the disk 14 by means of its converging action, the beam is reflected according to recorded information formed on the recording surface and picked up as a recorded signal. When a disk has high density, the aperture 2a is moved to the laser 12 and arranged so that the numerical aperture of the lens 13 becomes 0.6. By controlling the beam so as to enlarging a light beam of a peripheral beam from the laser 12, it is passed through the lens 13 of the numerical aperture 0.6 and the spot 17 is formed on the recording surface of the disk 14.

摘要： PURPOSE:To increase recording capacity and to make a recording and reproducing device thin by using a rotatable disk for a recording medium. CONSTITUTION:Laser beams radiated from a semiconductor laser 1 are converted into parallel beams by a collimator lens 6 and projected to a translucent recording medium 8. The recording medium 8 fully reflects the introduced parallel beams at an incident angle less than 45 deg. respectively on a front face 8b and a rear face 8c which are parallel to each other. In this case, the front face 8b is used as a recording surface and evanescent light generated on the face 8b is fetched into a scanning probe 11 composed of optical fibers. A fine opening 13 provided on the tip face of the scanning probe 11 optically scans the inside of a plane along the front face 8b of the recording medium 8. The evanescent light fetched into the scanning probe 11 is subjected to photoelectric conversion by a photodetector 14.

摘要： PROBLEM TO BE SOLVED: To provide a back projection device with a higher display quality.
SOLUTION: Luminous flux, emitted from a small projector apparatus 11 and containing image information is inputted through an opening 13 while spreading into a back projection device 12. The luminous flux, inputted from the opening 13, reaches at a first reflecting surface 14, and proceeds to a second reflecting surface 15. The luminous flux reached at the second reflecting surface 15 is subjected further to regular reflection with an approximately 0°, and returns to the first reflecting surface 14 again. The luminous flux reached at the first reflecting surface 14 undergoes a further reflection with approximately 60°, and proceeds to a third reflecting surface 16. The luminous flux, reaching the third reflecting surface 16, undergoes total reflection with approximately 30°, and it reaches at a screen unit 17.
