  • Patent number: 6352563
    Abstract: A printed cloth in which a dye is deposited in dots on the cloth to form a desired printed pattern. Said dot deposition is formed in a length of 0.05 to 0.3 mm to the longitudinal direction of the fiber in single fiber unit of the yarn constituting said cloth. A fine printed pattern is deposited clearly in good reproducibility. The printed pattern can be formed by using the dyes of the three primary colors or of the three primary colors and black color. It is preferred that Dyes I , II and III having a perceived chromaticity index (a) and (b) defined in the color range [CIE 1976 (L, a, b) space] on the cloth within the following range are used as said dyes of three primary colors and DyeIV is used as said black dye.

  • Patent number: 6016519
    Abstract: Disclosed is a system, for exchanging data among a plurality of devices, wherein a device can detect the state of another device without that device being powered on, and whereby usability can be enhanced.According to the system, during data communication a power supply device supplies power to a power reception device, and activates sections necessary for the power reception device. The state of the power reception device is detected by a power management unit, and the information that is obtained is transmitted across a data I/F unit to the power supply device, and stored in a storage unit. Based on the stored status information, the supply of power to the power reception device can be controlled.

  • Patent number: 5567515
    Abstract: The underside of a base layer consisting of one or more sub-layers is overlaid with an adhesive layer that is chiefly composed of an .alpha.-olefin copolymer that is based on at least two .alpha.-olefins selected from among .alpha.-olefins having 2-12 carbon atoms and which has a crystallinity of up to 10%, and said adhesive layer will develop an initial tack of at least 20 g/25 mm when attached to the surface of a stainless steel plate at 23.degree. C. The thus produced surface protective film, when attached to various kinds of adherends, will not experience separation of the adhesive layer from the base layer while developing strong initial tack, will experience only small changes in adhesive strength (peel strength) with the lapse of time after attachment to the adherends, is sufficiently low in blocking force to provide ease in film handling during the rewinding operation and it yet can be manufactured at low cost.

  • Patent number: 4987566
    Abstract: In case that the light beam emitted from a light source mounted on a base element is focused to a spot light on a data storage media to write the data, when the light beam reflected from the data storage media to return to the light source is reflected from the base element and focused again on the data storage media, it becomes difficult to precisely read/write the data on the storage media. In order to resolve the above problem, a light beam treating means is provided in the base element to prevent the re-incident light beams from being reflected toward the data storage media and focused thereon.
