摘要： Provided is a wireless communication system in which a plurality of channels are shared and one of the channels is adaptively allocated to a wireless communication terminal by a base station. The wireless communication terminal is provided with a channel requesting unit that requests the base station to allocate an individual control channel when a communication request is received from an upper control unit of its own terminal or the base station, and a state control unit that controls the state of its own terminal so that the state transits to an individual control channel connected state in which control information is transmitted/received by wirelessly connecting the individual control channel allocated from the base station. The base station is provided with a channel allocating unit that allocates one of a plurality of traffic channels as the individual control channel to be exclusively used for the wireless communication terminal in response to the request from the wireless communication terminal.

摘要： A first ball circulating hole and a second ball circulating hole for connecting a circulator are bored midway at a screw groove formed on an inner circumference of a ball nut, an intermediate groove path between the first and second ball circulating holes becomes the range of a ball screw track for circulating balls, and other ranges become a first outer track and a second outer track which are not the ball screw track. By making the groove depth of the intermediate groove path deeper than the groove depth of a first groove path of the first outer track and the groove depth of a second groove path of the second outer track, steps are formed between the ball screw track and the two outer tracks. These steps prevent an outflow of the balls from the intermediate groove path to the respective groove paths of the outer tracks.

摘要： To prevent stored information from being changed even at the occurrence of an abnormal condition in an upstream side of a system due to uncontrollable run of an OS. A nonvolatile storage means having data storage areas and management areas for them in units of predetermined physical addresses has an access protect definition table TLB in a predetermined physical address, and the table has access attribute information defining whether to permit or not access to the data storage areas in association with the physical addresses. The memory system itself possesses access attribute information defining whether to permit or not a write to and a read from the data storage areas in association with addresses to implement an access protect function for write and read. Therefore, the access protect function is maintained even if an abnormal condition occurs in a host device that manages the memory system or controls it as a peripheral circuit.

摘要： A small ultrasound diagnostic device is provided at a low cost that enables the appropriate control by a single power supply unit so as to give a predetermined transmission power to a driving waveform different for each mode without excess or deficiency and without affecting properties of the driving waveform. The ultrasound diagnostic device includes: an ultrasound generation unit (1) that transmits ultrasound; a waveform generation unit (2) that generates a single pulse or a burst pulse whose duty factor is variable in units of a time that is a period corresponding to a frequency outside a frequency band of the ultrasound generation unit (1) so as to drive the ultrasound generation unit (1); and a single power supply unit (3) that determines an amplitude of a driving waveform generated by the waveform generation unit (2). Thereby, an acoustic power of the transmitted ultrasound can be controlled without making the transmission amplitude variable.
