Abstract: An information terminal such as a PDA (personal digital assistant) having a plurality of display screens in particular. The information terminal is provided with a plurality of display devices stored so that they can be developed in a main unit of the information terminal. The information terminal includes a controller which controls start and display of any application displayed on each of the display devices. The controller displays a plurality of applications in a predetermined order each time the display devices are developed.
Abstract: A printer for executing recording onto media, including a head and a rotary encoder, wherein the head and the media are moved relatively. In the relative movement between the head and the media, the media may be moved relative to the immobile head, or the head may be moved relative to the immobile media. The rotary encoder outputs pulses corresponding to relative positions between the head and the media. The head starts recording onto the media based on the pulses output by the rotary encoder. When the pulses from the rotary encoder have not been output within a predetermined period of time, the printer starts recording onto the media based on a lapse of the predetermined period of time.
Abstract: A digital image display stand for enabling even persons who feel inferior to digital machines to easily view a transmitted digital image without performing intricate operation. The digital image display includes a reception section which receives digital image data transmitted via a communication line; a storage section which stores at least digital image data corresponding to one frame, of the digital image data received by the reception section; and an image display section which displays the digital image data stored in the storage section.
Abstract: The invention is an improvement in efficient use of a radio communications channel, and for inhibiting transmission of an unwanted radio wave on a SCO communications link established between Bluetooth radio communications terminals as well as reducing power consumption. A sound signal that transmitted along a SCO communications link is detected. When the signal is absent, the communications link is once disconnected and, the communications link is connected again when a sound signal is detected. Instruction for disconnection and reconnection of a communications link may be done by a control signal coming from a call button provided on the communications terminals.
Abstract: An optical printer capable of controlling the amount of exposure light, and so forth, accurately is disclosed, and the optical printer comprises a light source irradiating light and an optical shutter producing exposure light for exposing a photosensitive object by controlling transmission of the light from the light source.
Abstract: The irradiation device irradiates, at the time of recording main information, a first light beam having a first power and a second light beam having a second power on the pre-pits in a time-divisional manner. The light receiving device receives a reflected light of the first light beam from the pre-pits to produce a first light-receipt signal, and receives a reflected light of the second light beam from the pre-pits to produce a second light-receipt signal. The first detector detects the pre-pits based on the first light-receipt signal to produce a first detection signal, and the second detector detects the pre-pits based on the second light-receipt signal to produce a second detection signal. Then, the processor produces a logical sum of the first detection signal and the second detection signal to output a pre-pit detection signal.
Abstract: An apparatus for demodulating a phase modulation wave reduces an error rate of a demodulating circuit to perform a delay detection of an n-phase shift keying modulation wave without raising a clock frequency. When converting the received n-phase shift keying modulation wave into a rectangular wave, a waveform converting circuit for converting the n-phase shift keying modulation wave into a rectangular wave of a duty ratio which is larger or smaller than 50% is used. The rectangular wave is clocked through parallel registers of different lengths, outputs of the registers being operated on by exclusive-OR gates with the rectangular wave. Outputs of the gates are applied to respective one of a pair of counters, operated by a common clock signal, during periods of equality of outputs signals of the gates to provide a function of discriminating reproduction. A parallel/series converting circuit arranges upper bits and lower bits for reconstruction of each symbol of an original data message.
