Abstract: When a cube has been selected, and a touch operation has been canceled, a retouch determination area that is larger than the original selection area for selecting the cube is set based on a touch cancellation position. When a retouch operation has been detected within the retouch determination area after the touch operation has been canceled, it is determined that the same position as the touch cancellation position has been retouched, and the cube (object) is moved.

Abstract: A print setting means 50 has a first selection unit 52 that selects a first setting value out of a plurality of first setting value candidates related to printing and further has a second selection unit 62 that selects a second setting value out of listed second setting value candidates related to printing, where the second setting value candidates are different from the first setting value candidates and are listed depending on the first setting value. In the configuration of the print setting means 50 described above, the first setting value is notified to a printing apparatus 20 at each time of selection made by the first selection unit 52, whereas, at each time of selection made by the second selection unit 62, the content of setting is retained and thereafter notified to the printing apparatus 20 in response to instructions.

Abstract: In a mobile communication system, radio channel capacity can be secured. A plurality of base stations transmit to a mobile station information X0 and the like about diversity handover, and a reference signal (such as a perch signal). The mobile station measures received quality (such as a received power) of the reference signal. The mobile station makes a decision for each of the plurality of base stations as to whether the service area is to be selected as a candidate of a service area in which the mobile station will start new communication, and/or as a candidate of a service area in which the mobile station will stop current communication.

Abstract: A vicinity search using register point data in a designated area reduces search time. The vicinity search data include at least category information, names of register points and country information. The search device conducts the vicinity search by specifying any one of category information to which the register points belong, names of the register points and country information, or a combination, by option and display. The search device further uses category information with flags representing the presence and absence of the register point data, whereby the register point data are searched by referring to the flags.

In the case of using prescribed transmission rate and N-valued modulation scheme, logical channels to be used for transmission of paging signals among a plurality of available logical channels are determined by setting priority orders among a plurality of available logical channels such that a number of states of modulated signals becomes less than N when paging signal traffic is small.

Abstract: A paging system including one or more pagers having a transmitting function. The pagers can transmit to a base station a response upward signal acknowledging reception of a paging signal, and a pager initiative signal through direct sequence spread spectrum modulation. The pager assigns different spreading codes to the response upward signal acknowledging the reception of the paging signal and the pager initiative signal, so that the base station can receive them independently.

Abstract: A digital modulation and demodulation scheme for radio communications which is capable of reducing errors due to fading while maintaining the characteristic of the M-ary modulation and demodulation scheme that it is robust against interferences. At the transmitting side, transmission data are divided in advance into blocks of LN bits length each and each block is divided into N sets of L bits data sequences. Then, orthogonal codes of M bits length each corresponding to L bits codes given by the L bits data sequences are generated, and N sets of orthogonal codes for each block are multiplexed into a multiplexed signal, such that M bits constituting each orthogonal code are dispersed in time in the multiplexed signal. A digital modulation is then applied to a carrier using the multiplexed signal.

Abstract: In a radio paging system wherein a user carrying a radio paging receiver is paged by means of radio waves, and the radio paging receiver sends back a response signal when it has received a paging signal addressed to itself, the response signal is sent back by means of direct sequence modulation using a code uniquely determined in accordance with the base station ID signal, which is different for each base station, and which has been inserted in the paging signal sequence transmitted from the base station, or in accordance with the order of each paging signal within the paging signal sequence. As a result, the response signal can be transmitted at low power from each radio paging receiver, and effective utilization can be made of frequency, regardless of an increase in the number of radio pagers.

Abstract: In a mobile radio communication system wherein, in order to call a receiver from a base station, a paging signal containing address information corresponding to the receiver to be called is transmitted n times, the position of a paging signal that is transmitted for the second or subsequent time is determined, in accordance with a prearranged rule, in relation to the position of the same paging signal when it was transmitted for the first time, and the receiver achieves more efficient battery savings by stopping its receiving operation with respect to signal portions which have been confirmed as having already been received without error. The receiving operation is intermittently stopped at a timing corresponding to identical signal portions of the same repeatedly received paging signal.
