Abstract: For a printing system, a printing device and an information terminal are connected by communication. The printing device includes a wired communication unit configured to communicate by USB, a connection confirmation unit configured to confirm the connection to the information terminal, and a boot application determination unit configured to notify the information terminal of the application to be booted at the information terminal. The information terminal includes a wired communication unit configured to communicate by USB, a wireless communication unit configured to communicate with a server, an application existence determination unit configured to determine installation, a download site determination unit configured to determine a server, an install unit configured to acquire the application from the server and install, and an application boot unit configured to boot the application.

Abstract: A speech processing device includes: a dialog execution control unit that controls speech output and timings of speech recognition in accordance with dialog information including speech output information, speech recognition information and control information; a speech output control unit that outputs an output speech signal designated by the speech output information; and a speech recognition unit that executes speech recognition processing for an input speech signal using the speech recognition information. The control information includes speech output timing information for the output speech signal and speech recognition start timing information for the input speech signal. The speech recognition start timing information is specified by a time period that elapses from a first timing specified by the speech output timing information.

Abstract: A memory management apparatus suitable for reducing amount of memory usage and simplifying programs is provided. When an area allocation request has been inputted, an unused area having a size that is determined by area size information included in the area allocation request is searched for as a candidate area on the basis of a memory management table 400. And overlap flag corresponding to an adjoining area that is contiguous with the candidate area in its lower address orientation is read from the memory management table 400, and, based on the overlap flag, it is determined whether or not the adjoining area is an area that allows overlapped allocation. If it is determined the area is an area allowing overlapped allocation, a used area that overlaps with the adjoining area is allocated.

Abstract: A processor control device includes a processor executing an instruction, a module coupled to the processor through a bus and processing independently from the processor, the module is provided in a plural number and a polling processing unit coupled to each module, the polling processing unit stopping an operation of the processor depending on an execution status of the module processing at a time of an access request from the processor.

Abstract: Power consumption by a processor can be reduced without impairing the efficiency of processing by the processor. When a processor 2 inquires the operating status of a DMA controller 4 during a DMA operation, a clock controller 5 stops the supply of a clock signal to the processor 2 to prohibit the processor 2 from making inquiries about the operating status of the DMA controller 4. According to this arrangement, the processor 2 can continue processing until the processor 2 inquires the operating status of the DMA controller 4, that is, until it outputs a state-indication-register-read request signal, even if the DMA operation is being performed in the DMA controller 4. When the processor 2 outputs a state-indication-register-read request signal, the clock signal supply to the processor 2 is stopped.

Abstract: In a magneto-optical recording medium, a first dielectric layer 12, a recording layer 13, an auxiliary recording layer 14, a second dielectric layer 15 and a reflective layer 16 are sequentially laminated on a transparent substrate 11. Recording layer 14 is formed of a rare-earth transition-metal amorphous alloy having a film thickness of about several hundreds angstroms. Auxiliary recording layer 14 is also formed of a rare-earth transition-metal amorphous alloy. However, the Curie temperature T.sub.C2 of auxiliary recording layer 14 is 10.degree. K or more higher than the Curie temperature T.sub.C1 of recording layer 13, and the film thickness of auxiliary recording layer is ultra-thin, such as, 70 .ANG. or less. Further, the squareness ratio of auxiliary recording layer 14 at the Curie temperature T.sub.C1 of recording layer 13 is 0.7 or higher.

Abstract: In a magneto-optical recording medium, a protective layer 14, a first magnetic layer 11 formed of a light rare earth element-heavy rare earth element-transition metal alloy, a second magnetic layer 12 formed of a light rare earth element-heavy rare earth element-transition metal alloy, a third magnetic layer 13 formed of a light rare earth element-heavy rare earth element-transition metal alloy, another protective layer 15, and a reflection layer 16 are laminated in sequence on a transparent substrate 10. The first, second and third magnetic layers are sandwiched so as to form a recording film 17. The compositions of the first and third magnetic layers are so selected as to provide a large Kerr rotational angle in a short wavelength range (400 to 700 nm), which is high in the ratio of light rare earth element.
