Abstract: To accurately monitor the status of an antenna even when characteristics of the antenna chronologically change, the antenna is replaced, and the like. This device 1 includes a GPS receiver 11, a GPS antenna 12, a modem 12 for transmitting location information of a vehicle that is received by the GPS receiver 11, an antenna current source 13 and a current/voltage conversion unit 14 that detect the status of the GPS antenna 12, a storage unit 16 that rewritably stores a threshold for the status of the GPS antenna 12, and a control unit 18 that determines the status of the GPS antenna 12 and rewrites the threshold stored in the storage unit 12.

Abstract: The first method of the present invention includes the steps of: receiving from a user registered in advance the retrieval condition of qualification relevant information relating to the facilities management of a corporation to which the user belongs; obtaining the qualification relevant information corresponding to the retrieval condition from at least one of statute information and qualification information relating to the facilities management of the corporation, qualification information about a staff of the corporation, and information relating to a facilities manager of the corporation; and displaying the qualification relevant information corresponding to the retrieval condition on the terminal screen of the user.

Abstract: A heat sink apparatus of the present invention comprises a heat conductive base comprising a plate member having a first surface and a second surface, a plurality of heat dissipation fins projecting upwardly from the first surface and extending radially toward a circumference of the plate member, the second surface being adapted to be in contact engagement with a surface of the electronic device, the first surface slopping down radially toward the circumference of the plate member, and a fan assembly mounted above the heat dissipation fins. The second surface is substantially flat and a thickness of the plate member decreases radially toward the circumference of the plate member. The heat dissipation fins are arranged to define a non-finned zone of the first surface and the non-finned zone is a concave. The heat sink apparatus further comprises a casing includes an upper wall, a lower surface of which is positioned adjacent to upper edges of the heat dissipation fins.

Abstract: Derivatives of the antibiotic XK-62-2 are prepared by chemically modifying the antibiotic XK-62-2. An example of one such derivative is 1-N-[L-(-)-.alpha.-hydroxy-.gamma.-aminobutyryl]XK-62-2.

Abstract: A new biologically active substance, 1-HABA-seldomycin-5, is produced by chemically modifying the antibiotic XK-88-5. The composition of matter is useful as an antibacterial agent.

Abstract: A new compound which is useful as an antibacterial agent or a synthetic intermediate thereof and has the general formula: ##STR1## (wherein R is hydrogen, benzyloxycarbonyl or t-butyloxycarbonyl) is produced by reacting the compound XK-88-5 with an urethane-type amino-protecting reagent.

Abstract: A new antibiotic, 2'-deamino-3'-epiamino-3'-deoxy-XK-88-5 represented by the formula: ##STR1## is produced by chemically modifying the antibiotic XK-88-5 represented by the formula: ##STR2##
