Title: Conveyance device and conveyance method for block
Inventor: ARAKI HIROTAKA
IPC: E03F3/06
Filed: 2003-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a conveyance device for a block capable of reducing width of a digging hole and having excellent construction property.  <P>SOLUTION: This conveyance device conveys the block 1 having a top block part 2, side block parts 3, 3, and a bottom block part 4. This device is provided with a support body 11 arranged in the block 1 to support the top block part 2, leg parts 15, 15 provided in the front and rear of the support body 11, respectively, and coming into contact with the ground outside the block 1, and a running roller 16 for moving the leg parts 15 for a bottom part 8 which is a ground contact face. Since the top block part 2 is supported by the support body 15 to lift the block 1 and the block 1 is conveyed by moving by the leg parts 15, 15 in the front and rear of the support body 11, it is unnecessary to arrange the device outside the side block parts 3 and the top block part 2 of the block 1 to enable conveyance at site where there are restrictions in the direction of width and in an upper part.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Mobile communication system, program, recording medium, and mobile communication method
Inventor: MIYAHIRO EIICHI
IPC: H04L12/701
Filed: 2003-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a mobile communication system or the like which shortens the time required for change processing during movement over networks of various communication media, of an information terminal device 5 connectable to a plurality of communication media.  <P>SOLUTION: A reciprocation path other than triangular paths of conventional mobile IP is used to cause a server 50 to always recognize a mobile communication network which the information terminal device 5 selects. Since transmitting actual data from the information terminal device 5 to the server 40 serves as register operation in conventional mobile IP, the register operation is made unnecessary to shorten the time required for handover processing. Since the server 50 can always recognize the mobile communication network selected by the information terminal device 5 by using the reciprocation path, trouble resulting from IP address impersonation is avoided. Other simple protocols for encapsuling, for example, standard protocols of VPN can be utilized.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Diffractive optical element and laser beam machining device using the same
Inventor: FUSE TAKASHI
IPC: G02B5/18
Filed: 2003-02-06
Abstract: <P>PROBLEM TO BE SOLVED: To solve the conventional problem that direction of diffracted light beams is discrete and limited only to the direction of predetermined grid points in the conventional diffractive optical element (DOE) in which a unit pattern Y of a prescribed pattern is repeatedly parallelized lengthwise and crosswise and in which calculation is possible rather advantageously by high-speed Fourier transformation.  <P>SOLUTION: Transmissivity t<SB>mn</SB>is given to all pixels (m, n) constituting a DOE, with calculation all done for equations of the Fourier transformation in the directions of desired orientations α, β. An off-grid irregular diffraction pattern can be formed although calculation quantity is increased. Also, resolutions U, V can be made smaller values than λ/aR, λ/bS (λ is a wavelength, aR and bS are the size of DOE). A laser beam can be branched in arbitrary directions and numbers with high resolution. It is possible to emit a laser beam to multiple points in one lot at an arbitrary position and with high positional accuracy. It is also possible to realize free and highly accurate spot arrangement that is required for electronic components. The diffractive optical component has great effect on speeding-up and cost reduction of laser beam machining.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
