Abstract: A transmission bit and transmission power distributing method that can reduce the arithmetic amount in a multiantenna-input/multiantenna-output (MIMO) wireless communication system. This method comprises steps of calculating a signal-to-interference-noise ratio (SINR) gain after MIMO detection of each of transport substreams (S601, S602); optimizing, based on the acquired SINR gain, a transmission bit and transmission power distribution in the space domain for all transport substreams on a particular subcarrier in the frequency domain, thereby deciding a transmission bit and transmission power distribution parameters (S603, S604); and optimizing a transmission bit and transmission power distribution for adjacent subcarriers, by sequentially using the transmission bit and transmission power distribution parameters distributed on the subcarrier for which the transmission bit and transmission power distribution parameters have been decided (S605 to S610).

Abstract: To obtain a construction in which unnecessary learning can be avoided and optimal and stable positioning control can be carried out upon introducing a repetition control method in an optical disc device.A defect detection unit (5), a disc position detection unit (9), and a disc rotation speed detection unit (10) are provided in a disc control device comprising a repetition control device to control storing to and reading from a memory unit (3) used as a learning memory and to vary the number of memory divisions of the memory unit (3) on the basis of detection by the detection units. When components having periodicity are apparently due to partial surface runout or partial eccentricity, they are stored in the memory unit (3) by increasing the resolution and microscopic noise components and noise components having no periodicity are not stored in the memory unit (3). Therefore, it is possible to carry out focus tracking control stably even when disturbance such as device vibration or scratches on a disc is mixed.

Abstract: In a bidirectional power supply device, a DC-DC converter is connected such that the longer an ON time of the first switch becomes, the higher a voltage of a second positive terminal and a second negative terminal becomes. When stopping the supply of power from a first positive terminal and a first negative terminal to a second positive terminal and a second negative terminal, a control circuit turns OFF a third switch, and then operates a switching signal generation circuit so that the ON time of the first switch becomes a maximum. The switching signal generation circuit is operated so that the ON time of the first switch becomes a maximum with the third switch turned OFF in start-up when supplying power from the second positive terminal and the second negative terminal to the first positive terminal and the first negative terminal.

Abstract: A portable terminal capable of obtaining an input device having an intuitive and delicate instantaneous responsibility is provided by performing a manipulation of a second housing while viewing a display unit of a first housing.This portable terminal 10 includes a first housing 11 where a display 14 is provided; and a second housing 12 where a control unit 16 is provided. The second housing 12 is coupled to the first housing 11 in a freely pivotally rotatable manner along two directions perpendicular to each other around a first coupling shaft 18 and a second coupling shaft 19, which are two shafts intersected perpendicular to each other. In the portable terminal, the first housing 11 is griped by, for example, a left hand, and also the second housing 12 is griped by, for instance, a right hand corresponding to one's dominant hand. Since the second housing 12 is manipulated along a direction perpendicular to the first housing 11, an operation of an application program within the display is controlled while the display of the first housing 11 is viewed.
