Title: Apparatus for detecting position of vehicle
Inventor: TODA AKIRA
IPC: G01C21/00
Filed: 1990-11-22
Abstract: PURPOSE:To detect the present position of a vehicle correctly by making the starting point of a waterway agree with the arriving point, forming a road connected to the starting point and a road connected to the arriving point in the continuous road shape, and comparing the road shape with the running locus of the vehicle. CONSTITUTION:The position of a vehicle running on a running path, so-called a road, is sequentially operated based on the detected data from a detecting means having a bearing sensor and a distance sensor. Map data stored in a memory means 3 are checked. Thus, the running locus of the vehicle on the running path is computed. The starting point and the arriving point of a ferry waterway which is connected to the running path are made to agree. A forming means 7 is provided. The running path connected to the starting point and the running path connected to the arriving point are made to form as the continuous running-path shape in the forming means 7. The running path formed with the forming means 7 is compared with the running locus of the vehicle. The position of the vehicle is corrected in response to the result of comparison. Therefore, even if the ferry waterway exists on the path, the position of vehicle can be adequately detected.

Inventor: SOMA TOMIO
IPC: E02F5/02
Filed: 1993-11-22
Abstract: PURPOSE:To increase operability, by making the sub-shaft joint rotatable with respect to the main shaft joint and holding the middle parts of the main shaft and the sub-shaft with a bracket and a center rest arm respectively. CONSTITUTION:The main shaft 5 and the sub-shaft 6 are fixed to the main shaft joint 3a and the sub-shaft joint 3b of an auger 3 respectively. And the bracket 12 of a center rest 11 is attached to a leader 2 so as to freely slide. The shafts 5, 6 are attached so as to pierce the hollow shaft 15 of the bracket 12 and the sub-shaft insertion hole 16 of the center rest arm 13 respectively. The shaft 5 is prevented from deviation by the bracket 12 when excavating ground by driving the shafts 5, 6. When the shaft 6 is rotated normally or reversely by rotating the joint 3b by a rotary device, as the arm 13 is rotatably connected to the shaft 15, it can rotates freely in both directions. But it is fixed at a required place by a brake 14 and the shaft 6 is prevented from deviation by the arm 13. In this way, the position of an improved post can be freely changed and the verticality can be improved.

Title: Wireless network, its path control method and wireless communication controller
Inventor: YONEDA KENICHI
IPC: H04L45/85
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To enhance the performance and the reliability of a wireless network by stably transferring data in the wireless network whose channel quality changes every moment. SOLUTION: In the wireless network adopting a logical configuration where transfer paths are in existence among a plurality of wireless communication controllers in the case of transferring data from an optical sender to an optical destination, a control section 200 of a wireless communication controller being the sender transmits a path investigation frame to paths leading to the destination prior to start of transmission and discriminates paths such as those received earlier by the destination, paths with less retrial number of times or paths with a small channel load to decide the path to be used for the transmission. The wireless communication controllers acting like relay stations in each path obtain number of retrial times/channel load of its own and apply update processing to the path investigation frame and store the result.  Moreover, the wireless communication controller acting like the destination acquires path information (retrial times/channel load) on the way by data frames during communication, detects a fault when a value of the path information received by the destination exceeds a value stored in a threshold value storage section 211, and informs the sender about the occurrence of the fault in the path in use to allow the sender to select other path.

Filed: 1987-12-15
Abstract: PURPOSE:To enable an ink ribbon to be used effectively with respect to the width direction thereof by supporting the ink ribbon so that the ribbon can be moved in the width direction thereof relative to a printing head. CONSTITUTION:When the ink density at an end part in the width direction of a multi-time ribbon 12 is lowered, a base 7 is lowered by a stroke not more than the width of the ribbon 12 in a printing range of a thermal head 5, and printing is conducted by using a part on the inner side in the width direction of the ribbon 12 which part overlap partially with a ribbon part already used. When the ink density at the part on the inner side is lowered, a ribbon cassette 8 is inverted face side back, and a different part of the ribbon 12 is used for printing. As a result, the ribbon 12 is used over a three-character width, leaving an approximately one-character width at a central part in the width direction thereof unused. Therefore, when printing is conducted by opposing the central part of the ribbon 12 to the head 5, the multi-time ribbon 12 having a three- character width can be used dividedly at 5 stages. Thus, the multi-time ribbon 12 having a large width can be effectively used.

Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a three-dimensional picture display controller giving the same visual effect as travelling in the real world by automatically and properly varying the direction of one's eye while one's view point is traveling on a linear path. SOLUTION: A scene data storage means 2 stores a three-dimensional object arranged to the scene. The position of a view point update means 5 moves the view point along the path stored in a path storage means 1.

A rendering part 9 displays a CG (computer graphic) picture in a three-dimensional space obtained by looking at the direction of the eye from the view point. The relation between the path and the positional relation of the three-dimensional object is limited and the direction of the eye is controlled while the view point is traveling on the linear path to attain picture display like really walking on a path object.
