摘要:
Disclosed herein are an imidazole derivative represented by the following general formula (1): ##STR1## wherein R.sup.1 is a hydrogen atom, or an alkyl, alkoxy or alkoxycarbonyl group, and R.sup.2, R.sup.3 and R.sup.4 are the same or different from one another and are independently a hydrogen or halogen atom, an alkyl, halogenoalkyl, hydroxyl or alkoxy group, or the like, or a salt thereof, and a medicine comprising such a compound. The compound specifically suppresses the production of particular cytokine and is hence useful as an active ingredient for immune function modulators and the like.

Substituted quinolone derivatives represented by the following formula: ##STR1## wherein R.sup.1 represents a substituted or unsubstituted (hetero)aryl group, R.sup.2 represents H or an alkoxycarbonyl, substituted aminocarbonyl, cyano or like group, and R.sup.3 and R.sup.4 each independently represent H or a substituted alkyl, aryl, amino or like group, and salts thereof; pharmaceuticals containing the same. These derivatives and salts have excellent anti-ulcer activities.

A radio terminal and a radio communication system using the same, which enables power saving, the improvement of the quality of real-time communication such as voice communication, and a reduction of packet delay. An intermittent receiving interval for each radio terminal is set according to the operation mode of each application running on the radio terminal. Consequently, the intermittent receiving interval can be changed in cooperation with the operation mode of each application. Thus, power-saving control for the radio terminal can be carried out precisely. In addition, the radio terminal can assign priorities to data transmitted from the radio base station. The priorities are set according to the operation mode of each application running on the radio terminal, and the packets of real-time communication can be transmitted preferentially.

A wireless mobile communication device comprises first and second wireless interfaces that are individually powered from a battery. A controller sets the first wireless interface in a power-ON state for establishing a first wireless link with a first base station, makes a determination whether a handover is necessary from the first base station to a second base station, sets the second wireless interface in a power-ON state in response to the determination that the handover is necessary for making a search for the second base station, and sets the first wireless interface in a power-OFF state when the second wireless interface has established a second wireless link with the second base station. A wireless LAN module is connected to the controller for establishing a session with a remote communication device via the first and second wireless links.

A power saving method in a wireless LAN system is disclosed for permitting a terminal station to promptly transition to a doze state irrespective of the presence or absence of data destined to the terminal station in a base station. Upon receipt of a PS-Poll signal from a terminal station subordinate to a base station for prompting a transmission of data destined to the terminal station, the base station transmits an ACK signal to the terminal station for indicating a successful reception of the PS-Poll signal. Further, the base station transmits a data frame including data destined to the terminal station when there is such data, or transmits an empty data frame when there is no data destined to the terminal station. Then, upon receipt of the data frame (including the empty data frame), the terminal station transmits an ACK signal to the base station, and then transitions to the doze state in which a transmission/reception function is made inoperative.

A fishing reel has a brake apparatus disposed between a reel body and a spool shaft. The brake apparatus includes a rotary element mounted on the spool shaft to be rotatable relative thereto and to the reel body, a first brake mechanism for transmitting a braking force from the reel body to the rotary element, and a second brake mechanism for transmitting the braking force from the rotary element to the spool shaft. When the spool reaches a maximum rotating speed, rotating speed of the rotary element does not increase greatly since the first brake mechanism slips due to inertia of the rotary element. Subsequently, the rotating speed of the rotary element increases with lapse of time. As a result, the first brake mechanism effectively applies a braking force to the spool after the spool reaches the maximum speed.

A fishing reel comprises right and left side cases, a spool disposed between the side cases, a handle disposed adjacent one of the side cases for taking up a fishing line, and a cover openable and closable for covering an outer lateral region of the other side case. The cover extends to a lower position of the other side case and includes a bulge swelling out at an intermediate position between an upper position and a lower edge.

A double bearing reel which includes a protective device for a line guide. A protector having (1) a first cover portion covering the fishing line guide from above, (2) a second cover portion covering the front of the line guide, and (3) a line passing bore having a width larger than the reciprocation stroke of the line guide is supported across a pair of opposite side frames of the reel. The protector is slidable between a first position and a second position and is swingable relative to the side frames of the reel, when located at the first position, between a covering position and an open position with respect to the line guide. The protector is retained to the side frames at the covering position so that the protector is released from the side frames by sliding motion, thereby protecting the fishing line guide while maintaining easy access to the line guide to thread line therethrough.

A wireless transmission system includes an active wireless communication apparatus, a standby wireless communication apparatus, and a selecting apparatus for switching an operation. The standby wireless communication apparatus receives a signal transmitted from an opposing apparatus. When the standby wireless communication apparatus detects a failure information indicating that a failure has occurred in the active wireless communication apparatus as a result of reception, the standby wireless communication apparatus performs notification that the failure has occurred in the active wireless communication apparatus. The selecting apparatus that has received the notification performs switch control for switching the operation. Accordingly, it is possible to continue communication in a short switching time in case of a failure while maintaining high frequency utilization, for example.
