Abstract: A portable electronic device includes a reception unit (GPS receiver) that receives a positioning signal, and a power supply unit that supplies the reception unit (GPS receiver) with power. An intermittent operation range including an upper limit of an operation ratio of the reception unit (GPS receiver) is set, based on power consumption status of the power supply unit. The reception unit (GPS receiver) is intermittently operated within the intermittent operation range that is set.

Abstract: A printer driver that permits a user to efficiently confirm the contents of a printing setup for a printer. For each of the printing setup entries, a printing setup comparison unit compares the initial printing setup contents with the current printing setup contents. When the printing setup comparison unit ascertains that a difference exists between the initial printing setup contents and the current printing setup contents, the printing setup comparison unit outputs, to a printing setup display unit, a differential printing setup that includes differential printing setup contents, which indicate the current printing setup contents for which the difference exists, and a differential printing setup entry, which is the printing setup entry that corresponds to the differential printing setup contents. The printing setup display unit displays the differential printing setup.

Abstract: A method for manufacturing a thin metal film with an embossed pattern, which enables the precise transfer of the embossed pattern and generates a strong interference color is provided. An embossing belt 10 having an embossed pattern formed on one surface thereof is coated with a thermosetting transparent resin 12. The transparent resin 12 is dried and cured and is coated with PVA which is sintered to form a PVA layer 20, whereby the transfer of the embossed pattern is completed. After that, the transparent resin 12 with the PVA layer 20 bonded to the surface opposite to the embossed pattern is peeled from the embossing belt 10 and reeled in, and an aluminum layer 24 is deposited on the surface of the belt 10 on which the embossed pattern is formed. The aluminum layer 24 is coated with another transparent resin and the PVA layer 20 is removed through a dissolving step. Resulting resin layers are pulverized to create a hologram pigment.

Abstract: The automatic image changing and reproducing display device comprises, in a medium storage portion, an automatic image changing circuit and a plurality of memory circuits composed of semiconductor elements, such as ROMs, having a memory capacity that is sufficient for storing image information as digital signals. A particular piece of digital image information is selected by changing the memory circuits by means of the automatic changing circuit. A decoding circuit executes a decoding processing for the particular digital image information which has been selected and outputted from the memory circuits.

Abstract: Embossed metallic flakelets have high damage resistance and can be produced readily. A method for production is also provided. The embossed metallic flakelets are produced by dip-coating an organic-inorganic composite layer 12 on upper and lower sides of a carrier layer made of a PVA film or the like by a sol-gel process, and pressing an original embossed pattern 14 having an embossed pattern against the organic-inorganic composite layer 12 under pressure to transfer the embossed pattern onto the organic-inorganic composite layer 12. A sample having the transferred embossed pattern is sintered, to form a metallic film 10 on the organic-inorganic composite layer 12 by deposition or the like.

Abstract: An improved method of preparing embossed metallic flakelets for a hologram pigment improves productivity through a simpler process. A metallic foil 12 is first pressed between a cooperative pair of dies 10 having mutually complementary embossed patterns to thereby transfer to the surfaces of the metallic foil 12 the embossed pattern of the dies 10. Finally, the pulverized metallic flakelets are mixed with predetermined other ingredients to make a hologram pigment.

Abstract: A holding case has an intermediate packing member for only a card-type object. The intermediate packing member has a cavity for receiving the card-type object and holding mechanism for holding the card-type object. The holding mechanism has first and second claws which projects into the cavity. The second claw formed on a beam which is formed by forming a slit beside a base of the second claw. The beam bends in response to external force supplied from the outside, consequently projecting degree of the second claw into said cavity changes in response to the external force. An external casing member is based on ISO standards for a CD case.

Abstract: A heat accumulator for storing latent heat wherein said latent heat is evolved by applying an electric voltage. The heat accumulator comprises a heat storage material, a pair of spaced electrodes consisting of an anode and a cathode disposed inside said heat storage material, a means to maintain seed nuclei for inducing crystallization of supercooled state of heat storage material in order to evolve latent heat, and a means for applying an electric voltage between said anode and cathode.

Abstract: In a image pickup apparatus having three cameras for use in picking up a seamless panoramic image for a multi-screen, angles of view of the three cameras are jointed with each other without any overlapping or dead areas by making a side boundary line of one camera match with a complimentary side boundary line of another camera, the two outside cameras receiving an image in reverse through two reflection mirrors. The two reversed images are electrically or optically inverted by inversion sections to obtain original images.

Abstract: A voice conference system using echo cancelers. The system consists of at least two microphone to send out voice signals to a remote location, and a loudspeaker which receives in voice signals from the remote location. To prevent the microphone from picking up the loudspeaker sound, each microphone is hooked to the separate terminal of a comparator. Thus the a person's voice in one microphone will pass, but the loudspeaker sound being received equally by both microphones will be cancelled.

Abstract: In a scrambled-communication system, a transmitting station generates a scrambling noise having a periodically-recurrent series of noise patterns and scrambles an information signal by simply summing the scrambling noise to the information signal, whereby the information signal is totally unintelligible by an interceptor. At a receiving station, a noise-cancelling signal is generated by an adaptive transversal filter and supplied to a subtractor where it is combined with the scrambled signal to recover the information signal. For generating the noise-cancelling signal, a descrambling noise identical to the scrambling noise is generated. The filter has a tapped-delay line for receiving the descrambling noise and a plurality of variable tap weights connected respectively to taps of the tapped-delay line.
