摘要:
A method for demodulation where a plurality of preliminary data rows for creating the demodulated data are created according to intervals, each of which is a interval between peaks in a read signal coming from a magnetic head. Each preliminary data row includes first individual data identified according to the intervals, wherein a plurality of bits constitute the first individual data. At the time of creating the preliminary data row, standard intervals are identified for judging a first individual datum to be either “0” or “1”, and the standard intervals are assigned in a template saved beforehand. Then, intervals for judgment are compared with the standard intervals assigned in the template, with respect to each bit of each bit patterns. A bit pattern in relation to the preliminary data row is identified according to the comparison result, in order to set the preliminary data row with the identified bit pattern.

摘要:
A vapor deposition apparatus for depositing thin film on substrates in which solid starting materials are used. In this apparatus, a carrier gas flows up and down in the same direction as gas convection, such that the effect of gas convection is minimized and film thickness and impurity concentration are uniform over the substrate surface. This uniformity is achieved by orienting a main reaction tube in a vertical direction, attaching two branch reaction tubes at the top of the main reaction tube, and venting carrier gas out the bottom of the main reaction tube. Alternately, the main reaction tube can be oriented horizontally, with the substrates being carried on a holder within a container having pores on its top and bottom.

The disclosure is directed to a method for converting between heat energy and electric energy which is characterized in that a carbon intercalation compound is employed as a thermoelectric material by utilizing a temperature difference in a direction perpendicular to the structure of carbon layers, or a method for producing a light-heat converting material which is characterized in that a thin metallic layer like a translucent mirror is caused to adhere to the inner surface of a light transmissive hollow tube by pyrolytically decomposing at a temperature approximately below 1000.degree. C., with hydrocarbons being introduced into the hollow tube at the rate of a predetermined amount per hour.
摘要:
A thin-film electroluminescence (EL) device capable of displaying multiple colors has a laminated structure wherein back electrodes in stripes, a lower dielectric layer, a luminescence layer, an upper dielectric layer and transparent electrodes in stripes are sequentially formed on a transparent substrate in this order. The back electrodes intersect the transparent electrodes at right angles, and areas of the device where the back electrodes confront the transparent electrodes form picture elements. This device also has at least first and second color filters. The first and second filters are placed not only in corresponding picture-element areas of the transparent electrodes, but also in non-picture-element areas of the transparent electrodes and an upper dielectric layer such that the first color filter overlaps the second color filter in the non-picture-element areas. The first and second color filters in combination have transmissivities to visible lights similar to those of a black filter, thereby restraining external light coming to the non-picture-element areas from being reflected. Further, the device can include a groove in a transparent sealing plate formed above the transparent electrode. The transparent sealing plate is bonded to the transparent substrate with an adhesive and the groove captures excess adhesive to avoid interference between the adhesive and the picture elements.
摘要:
A thin film EL panel emits its light in response to the application of an electric field so as to make it possible to correspondingly create a multi-color display. The display created is higher in light emission efficiency, lower in power consumption, higher in function and higher in quality with the electrodes being sufficient in a heat resisting property with respect to the main thermal process.
