IPC: G06T7/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To accurately and rapidly determine a weld line center position, by obtaining the shape of the outer-periphery part of a welding part within a plane that orghogonally crosses the weld line as the aggregate of height coordinates at a discrete point for each fixed distance from a reference point, and by calculating a weld line center position index by using a specific expression. SOLUTION: As a method for determining a weld line center position, the shape of the outer-periphery part of a welding part within a plane that orthogonally crosses the weld line is obtained as the aggregate of height coordinates at a discrete point i for each fixed distance from a reference point. The i of a value being derived according to  P(c+1)-P(c-1)} based on the coordinates P (i) is integrated from 1 to N, a weld line center position index Q (c) is calculated according to the expression, and the same time the position of the (c) for extremely bringing the weld line center position command Q (c) close to 0 is determined as a weld line center position. In this case, the i, c, and N are set to a positive integer (i=0 at the reference point), the positive integer indicating a position from the reference point, and the positive integer, respectively.

Title: Inside/outside air controlling device for vehicle air conditioner
Inventor: HONDA YUJI
IPC: B60H1/00
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent blow-off temperature of conditioning air from rising when inside air circulation mode is replaced by outside air introduction mode at a low vehicle speed by providing a correcting means which performs correction so that cooling load at a given switching value becomes low as vehicle speed becomes low. SOLUTION: A target opening of an inside/outside air switching door 16 is determined so that as cooling load in a car room becomes lower than a given value, inside air introduction amount becomes small, and outside air introduction amount becomes large. The target opening can be varied according to vehicle speed correcting value. The vehicle speed correcting value is set according to value detected by a vehicle speed sensor, and corrected so that the lower the vehicle speed is, the lower cooling load is. Therefore, because hot outside-air in an outside-air introduction duct is hard to be introduced into an air conditioner case 2 at low vehicle speed, hot outside-air can be prevented from entering into the air conditioner case 2 during vehicle parking. Thus, blow-off temperature of conditioning air can be prevented from rising.
