Abstract:
An electrode structure is provided which is capable of efficiently using a material that can be a non-polarized electrode component, allowing the material to fully demonstrate the effect as the non-polarized electrode and maintaining the performance. This electrode structure comprises an insulating base (13), a polarized component layer (first layer) (12) laminated on the insulating base so as not to penetrate the insulating base, the polarized component layer comprising a conductive paste or metallic foil which is predominantly made of a component that can be a polarized electrode, and a non-polarized component layer (second layer) (11) provided on the polarized component layer, the non-polarized component layer comprising a conductive paste which is predominantly made of a component that can be a non-polarized electrode.
Abstract:
A method for exposing an optical disk master includes rotating a substrate disk coated with a photoresist, focusing a beam on the photoresist for exposure through an objective lens, and exposing the photoresist so as to form tracks on the substrate disk in its circumferential direction. At this time, the beam is deflected at least temporarily by passing through a deflector. The beam is divided into a first beam and a second beam after passing through the deflector, and the first beam is focused on the photoresist. A difference between the current position and the target position of an optical path of the second beam is detected, and the deflection operation of the deflector is corrected based on the difference so that the optical path of the second beam is located at the target position. This method can improve the track pitch accuracy of an optical disk having a narrow track pitch.

A fuel cell system comprises a medium-circulating passage for supplying, in a circulating manner, a temperature-adjusting medium to a fuel cell stack, and first and second temperature sensors for detecting medium temperatures at a temperature-adjusting medium inlet and a temperature-adjusting medium outlet. The medium-circulating passage is provided with a pump for circulating the medium, a heater for heating the medium, a radiator for cooling the medium, a bypass passage for bypassing the radiator, and first through third opening/closing valves for selectively supplying the temperature-adjusting medium to the radiator and the bypass passage.
Abstract:
A printing device according to the present invention includes a dye tank for containing a powdered vaporizable dye, an entrance section for liquefying the powdered vaporizable dye and a vaporizing section for radiating a laser light beam onto the liquefied dye transported to it by the entrance section for vaporizing the liquefied dye for thermal transcription of the vaporized dye onto a photographic paper. In this manner, printing may be made without employing an ink ribbon or a thermal head and hence the saving in power and the reduction in size and costs of the printing device may be achieved. Besides, the printing time may be shortened, while the size of the printing paper, may be set freely.A photographic paper according to the present invention includes a light absorbing layer between a receptor layer and a photographic paper base. Since the light absorbing layer is capable of absorbing the light efficiently for evolving heat efficiently, the receptor layer may be heated directly to assure a high quality of the printed picture.
