Title: Method of detecting and storing data for road network image display in data memory
Inventor: RAINHARUTO HERUDERUFUAA
IPC: G01C21/32
Filed: 1989-06-13
Abstract: PURPOSE: To facilitate the navigation of a vehicle by equalizing the conventration degrees of road base points along roads and outputting them to a data memory with data of base points and a road identification signal. CONSTITUTION: Base point coordinates having addresses belonging to the characteristic base points 19 in the respective roads 18 are called and midpoints A, A' between the first base point and the third base point 19 is detected at every three sequentially continuous base points 19 which are selected and they are middle-stored. Then, an interval b, b' from the second base point to the midpoint A, A' between the first base point and the third base point 19 is detected. When the interval b, b' is smaller than a limit value (a), the second base point 19 is suppressed with data of the base point. Then, the base point 19 which is not suppressed is outputted to the data memory with data of the base point and the road identification signal. Thus, navigation becomes easy.

Title: Permanent magnet erasing head
Inventor: KOIZUMI NOBORU
IPC: G11B5/325
Filed: 1982-08-26
Abstract: PURPOSE:To reduce the even-order distortion which is generated when a magnetic tape is reproduced, by magnetizing with polarization the tape rubbing surface so that the magnetic field intensity is gradually reduced in the tape traveling direction and dividing several poles counted from the final pole into magnetized and unmagnetized parts in the track width direction. CONSTITUTION:The rubbing surface of a magnetic tape 40 is magnetized in five N and S poles, for example, so that the magnetic field intensity is gradually reduced in the tape traveling direction (an arrow B). Then three poles counted from the final pole are divided into a magnetized part and an unmagnetized part (oblique lines). In such a way, a permanent magnet erasing head main body 50 is formed. A dummy head 60 is united the main body 50 to one body. In such a constitution, two regions having opposite polarities to each other exist within a track width in terms of DC residual magnetization with 1:1 ratio obtained between both regions. Thus the even-order distortions are eliminated with each other. As a result, the even-order distortion can be reduced when a magnetic tape is reproduced.

Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To improve workability by providing a reading device detecting the rotation state of a cap covered on the bolt of a fixing metal at the position facing the fixing metal fixing a rail to a crosstie on a bogie moved on the rails. SOLUTION: The switch of a console 4 is turned on, and a bogie 1 is pushed forward via a handhold 11. When the front sensor 21 of a reading device 2 detects a cap put on the bolt of a fixing metal fixing a rail 9 to a crosstie, the cap is photographed by a camera 22 and displayed on a display 30. If the indicator image of the photographed cap coincides with the reference display, it is judged that the cap is not rotated and the bolt is not loosened. If the indicator image does not coincide with the reference display, it is judged that the cap is rotated and the bolt is loosened, and the position of the bolt is reported to a bolt fastening man. The rotation state of the cap, i.e., the loosening of the bolt, can be detected with high efficiency, and workability can be improved.

Filed: 1992-06-09
Abstract: PURPOSE:To flexibly change the configuration of a system by dividing plural processors into the various kinds of combination by providing a circuit combining a computing element and a selector or the like as basic structure and hierarchically connecting those circuits. CONSTITUTION:In the case of entire synchronization, the arithmetic results of computing elements 11 and 12 to AND synchronizing signals outputted from several processors are extracted from the (n+1)th outputs of least significant basic synchronizing circuits 8 and 9 and impressed to a high-priority basic synchronizing circuit 10. The high-priority basic synchronizing circuit 10 receiving these results ANDs synchronizing signals outputted from the several low- priority basic synchronizing circuits 8 and 9 and outputs this result to the higher- priority basic synchronizing circuit. Then, the most significant basic synchronizing circuit 10 selects the synchronizing signal transmitted from the circuit itself corresponding to a selector 16 and returns it to the low-priority basic synchronizing circuits 8 and 9. In the case of partial synchronization, the result is not outputted to the high-priority circuit but returned to the low-priority basic synchronizing circuit or processor.
