    Abstract: A magnetic erasing head for magnetic recording apparatus using a static magnetic field. The erasing head includes at least three magnetic poles all of which are arranged to scan the same recorded track on the tape. The first and third poles have the same polarity while the second pole has opposite magnetic polarity. The first pole is arranged to engage the full width of the track and magnetizes it with one polarity. The second pole faces the upper half of the track and magnetizes it with the opposite polarity. The third pole engages the lower half of the track and magnetizes it with the same polarity as the first pole. After passing by these three poles, substantially one-half of the recording track is magnetized with one polarity and the other half of the track is magnetized with the other polarity so that distortion of output signals is maintained small or eliminated for various magnetic tapes having different coercive force values.

    Abstract: The present invention relates to an erasing head for a magnetic recording apparatus using a static magnetic field. The erasing head consists of a plurality of magnetic poles having surfaces which confront the recording tape. The first and second poles have polarities opposite to each other. The first pole is arranged to engage a recording track along its full width and magnetizes it to a given polarity. The second pole is arranged to engage the upper half of the track and magnetize it to the opposite polarity. Each half track is magnetized to opposite polarities so that the distortion of output signals is reduced, when the signal is reproduced by a reproducing head engaging both half tracks.

    Abstract: A recording and/or reproducing apparatus includes a base member at least having a rotation driving mechanism for rotationally driving a disc housed in a disc cartridge, a holder into which is inserted the disc cartridge and an ejection lever formed by an elastically flexible lever. The holder is mounted for movement between a first position in which the disc inserted in the disc cartridge is loaded on the rotation driving mechanism and a second position in which the disc housed in the disc cartridge is spaced apart from the rotation driving mechanism. The second position is higher in level than the first position. The ejection lever is elastically flexed by the disc cartridge inserted into the holder from a position protruded into the holder to the position extending along the back side of the holder. When elastically flexed to the position extending along the back surface of the holder, the ejection lever is engaged with the holder moved to the first position. When the holder is moved from the first position to the second position, the ejection lever is disengaged from the holder and is elastically restored in the direction of being intruded into the holder to eject the disc cartridge from the holder.

    Abstract: PROBLEM TO BE SOLVED: To forcibly change the power mode of ambient radio communication apparatus to enable the apparatus to perform a receiving operation, in an autonomous distributed type radio network. SOLUTION: A current parameter table holding part 110 holds a parameter table including information about the power mode of radio communication apparatus 100. The information about the power mode is used to control a power mode in a power mode control part 160. The parameter table is transmitted to peripheral stations by a transmitting part 120. Also, parameter tables of the peripheral stations are received by a receiving part 130 and stored in a received parameter table holding part 140. A parameter table update control part 150 attempts to update the current parameter table stored in the current parameter table holding part 110 on the basis of the received parameter table stored in the received parameter table holding part 140.

    Abstract: PROBLEM TO BE SOLVED: To attain efficient packet transfer in a network comprised of an existing network and a new network. SOLUTION: In the communication device, if a destination judging section 212 judges that a destination address of a received frame does not match an address in a link layer of a communication interface Y210 which receives that frame, a link layer path retrieval section 214 retrieves a transfer destination address corresponding to the destination address of the received frame and a transfer flag indicating that a higher-layer path table 203 should be referenced, from a link layer path table 213. As a result of the retrieval, if the transfer flag is set to the destination address of the received frame, a process discrimination section 215 sends the frame to a host via a header removal section 216. If the transfer flag is not set, on the other hand, the frame is transferred after its transfer destination address is rewritten by an address rewriting section 217. COPYRIGHT: (C)2007,JPO&INPIT
