  • Patent number: 7642970
    Abstract: An antenna device is provided which is capable of operating in a wider band of frequencies (in a plurality of transmitting and receiving frequency bands), achieving an excellent gain, maintaining non-directivity of vertically polarized waves in each of the transmitting and receiving frequency bands, and saving space. The antenna device includes the first antenna 101 being a chip-type antenna operating in a GSM band, second antenna 102 being a pattern antenna operating in DCS and PCS bands, third antenna 103 being a layer-stacked antenna operating in an UMTS band, all being mounted on a substrate 100. The second antenna 102 is connected to a line 105 extending from a power feeding port 104 connected to the first antenna 101. A gap is interposed between the second antenna 102 and third antenna 103 wherein the second antenna 102 is capacitively coupled to the third antenna 103 on the substrate 100 with no antenna switch being provided.

  • Publication number: 20090000971
    Abstract: A cling wrap case is provided, where even a polyethylene cling wrap film can be easily, assuredly and safely cut off, and concurrently, that is user-friendly, and that enables resource saving generally because this is not disposable but it is repeatably re-usable. The cling wrap case is made form a synthetic resin, and is equipped with a storage case in which a cylindrical cling wrap roll is stored, and a cover, rotatably attached to the storage case, which covers over the storage case to be openable, and which concurrently has a cutter member that cuts off a pulled-out amount of cling wrap film. The cover is constructed so that when the storage case is closed, the pulled-out amount of cling wrap film is cut off by the cutter member.

  • Publication number: 20080107727
    Abstract: A multiple-unit oral sustained release preparation is provided which allows controlled release of imidafenacin [4-(2-methyl-1-imidazolyl)-2,2-diphenylbutylamide]. The preparation serves to ensure a prolonged effect of imidafenacin and prevent rapid elevation in the blood levels of imidafenacin. Specifically, granules or powders comprising imidafenacin dispersed in a water-insoluble polymer or a higher alcohol are used in the preparation. These preparations achieve sustained release of imidafenacin since the molecular network structure that the water-insoluble polymer or the higher alcohol forms during the preparation of the granules or powders serves to control the rate of diffusion of imidafenacin in water. Granules comprising a core granule having two layers of an inner imidafenacin coating and an outer water-insoluble polymer coating are used in the preparation. The water-insoluble polymer coating serves to control the rate of diffusion of imidafenacin in water and ensure sustained release of imidafenacin.

  • Patent number: 5254212
    Abstract: A method of making a layered electrostrictive displacement device by forming sheets of an electrostrictive material alternately with internal electrodes. The laminate formed therefrom has two opposite surfaces at which the ends of the internal electrodes are exposed and two other opposite surfaces at which alternate layers of the internal electrodes are exposed. Temporary external electrodes are formed on the latter mentioned opposite surfaces. Alternate layers of the exposed portions of the internal electrodes are plated at one surface of the laminate with a metal while using a temporary external electrode as a cathode. The exposed portions of the other internal electrodes are plated with metal using another temporary external electrode as a cathode. The non-plated portions of the plated surface are selectively removed to form recesses, and an insulating film is formed on the recesses.

  • Patent number: 4226491
    Abstract: An electronic device comprising a printed circuit board unit contained in a protective cover, and which also serves as a guide member when the electronic device is inserted into a mounting chassis. The cover is constructed from a member formed in one piece, the member having cover portions and flexible hinge portions for permitting the cover portions to be pivotally moved with respect to each other between open and closed positions of the cover. The printed circuit board unit has a printed circuit board which is integrally formed at respective opposed ends with an electrical connector and a handle, which both project out of the cover. Such construction is simple and inexpensive to manufacture.
