Title: Joint structure of panel
Inventor: MORITA MAKOTO
IPC: E04B2/74
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To control hole formation or cracking in a surface material that may be caused by a sewing nail. SOLUTION: Panels 1 each of which has a surface material 2 made of a gypsum board and mounted on a wooden frame 3 are joined together by a sewing nail 4 driven diagonally from the surface material 2 of one panel 1 toward the frame 3 of the other panel 1, the diameter of the head 4a of the sewing nail 4 being 1 to 1.5 times that of the shank 4b. When the sewing nail 4 is driven diagonally, its head 4a is also inclined relative to the surface of the surface material 2 and is therefore embedded deeper on one side than on the other, whereas if the inclination angle of the sewing nail 4 is the same, then the greater the head 4a, the deeper the former side is embedded; since the diameter of the head 4a of the sewing nail 4 is 1 to 1.5 times that of the shank 4b, the embedded depth of one side of the head 4a of the sewing nail 4 can be made small.  A hole 5 formed in the surface material 2 made of the gypsum board becomes smaller accordingly, and cracking of the surface material 2 can be made as small as possible.

Title: Satellite radio wave catching apparatus of gps receiver
Inventor: ANDO HITOSHI
IPC: G01S19/24
Filed: 1990-04-12
Abstract: PURPOSE:To rapidly catch a satellite radio wave by performing narrow-band search during the predetermined time calculated by dividing the capture range of PLL by the Doppler change rate of the receiving frequency of the satellite radio wave. CONSTITUTION:A satellite radio wave is searched within a wide band while the search frequency of PLL is changed over the total width of a range wherein the satellite radio wave can not be received for a definite time during catching and the receiving frequency thereof changes in the max. degree. When the satellite radio wave becomes impossible to receive at this time, at first, band-wide search is performed during the predetermined time calculated by dividing the capture range of the PLL by the Doppler change rate of the receiving frequency due to a satellite. This search is set to the range of the max. frequency change centering around the receiving frequency at the time when reception becomes impossible and estimated from the capture range of the PLL and the moving speed of a GPS receiver. When re-catching is impossible after the elapse of a predetermined time, wide-band search is performed centering around the estimate receiving frequency calculated from the Doppler frequency at that point of time on the basis of stored orbit data. In either case, a re-catching time can be shortened.
