Title: Electrosurgical device
Inventor: HIJII KAZUYA
IPC: A61B18/12
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To prevent the carbonization of a living tissue and the adhesion of it to an operation instrument (electrode) by surely judging the end of a coagulation treatment regardless of contact area of the living tissue with the electrode holding the tissue and the thickness of the tissue which is held by the operation instrument (electrode). SOLUTION: A control part decides a maximum current value Imax as a first target value so as to permit output power to be a previously set initial setting value. Then the thickness (t) of the tissue 4a and the contact area A of the tissue 4a with the electrode 3 holding the tissue is obtained through the use of the combination (Imax, T) of Imax and a time T required till the value becomes Imax. The combination (A, t) of the obtained contact area A with the thickness (t) of the tissue is compared with the combination (Aset, tset) of the contact area Aset and the thickness tset of the initial setting value. Then the subsequent output of high frequency power and a coagulation end current value as a second target value are decided by the comparison result.

Title: Method of detecting contact condition in length measurement
Inventor: TOKIDA HARUHIRO
IPC: G01B21/30
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To detect a contact having accurately contacted to a work, without contacting it with pressure to the work or without greatly displacing it.

Filed: 2000-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a front image pickup device for a vehicle which can accurately correct the fitting panning angle of a camera even when the vehicle does not travel in parallel to a road while line. SOLUTION: This device has a camera 5 which picks up an image of the road surface in the travel direction, a vehicle speed sensor 6, a steering wheel angle sensor 7, and an image processing arithmetic part 8 which inputs and processes their signals. The image processing arithmetic part 8 detects the white line on the road surface, detects the lateral deviation and yaw angle of the vehicle from the white line to calculate the movement distance, and performs the same process after movement to judge whether or not the white line is straight in the movement, thereby judging whether or not the vehicle travels straight in the movement. When the vehicle travels straight, the angle between the travel direction of the vehicle and the white line, i.e., the real yaw angle is calculated from the vertical deviation and movement distance from the white line to the vehicle at the two points.  Further, the real yaw angle is subtracted from the angle between the white line and the axis of the camera (yaw angle including a panning angle) to calculate the real camera fitting panning angle ϕ.
