Title: Inspecting method for surface state
Inventor: NAKADA YUKITOSHI
IPC: G01M13/02
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To accurately detect the outer shape of a surface part for inspection by detecting the surface part for inspection as a specific color that is not sensed with either of three colors, and processing an image of color components in which this specific color is not sensed. SOLUTION: An inspecting device 1 processes using an image processor 5 an image photographed by a color camera 2 capable of reading a surface for inspection with three of R (red), G (green), and B (blue) colors, and monitors it. A tooth surface part J, for example, is detected as a specific color (yellow) that cannot be sensed with B of the three colors R, G, B, and this B-component image is processed. The tooth surface part J and its boundary with its surroundings (white tape) can be clearly discriminated from each other, thus detecting the outer shape of the tooth surface part J with precision. Thereafter, a masking image corresponding to the tooth surface part J with the color components (R, G) with which the yellow component can be sensed is processed to detect a tooth contact part K inside the tooth surface part J and to enable it to be displayed with shades.

Title: Railroad truck system
Inventor: KURAMOTO HIROSHI
IPC: B61B13/00
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To allow a plurality of railroad trucks to travel simultaneously with a relatively small power source by limiting the number of railroad trucks being accelerated simultaneously to a given number or less thereby lowering the instantaneous maximum power of railroad truck system. SOLUTION: High frequency power is applied to a feeder line 10 from a power supply and one power supply is used entirely for a railroad 2. A railroad truck 4 travels through a travel unit 14 comprising a servo motor wherein power consumption during constant speed travel is significantly lower than that during acceleration. On the contrary, instantaneous maximum power consumption is high during acceleration and maximum instantaneous power consumption of the entire railroad truck system depends on the number of railroad trucks 4 under simultaneous acceleration state. When the number of railroad trucks under simultaneous acceleration state is limited within a range of 1-3, instantaneous maximum power consumption of the entire railroad truck system is confined within the range of power supply capacity and noncontact power supply can be carried out smoothly with a small power supply.

Title: Acceleration slip controller
Inventor: KOTANI AKIRA
IPC: F02D45/00
Filed: 1991-09-30
Abstract: PURPOSE:To prevent worsening of acceleration by regulating reduction of a torque when traction control is started from a stand-by control condition, in an acceleration slip controller. CONSTITUTION:A throttle valve M4 provided on an intake passage M3 of an internal combustion engine M2 is operating/closing-controlled by a traction control means M1, at the time of acceleration slipping where driving wheel speed of a vehicle exceeds an aimed driving wheel speed based on a car body speed, and the acceleration slipping is thus reduced. Ignition timing or the amount of fuel supply is controlled for a predetermined period after starting of the traction control, by a torque reduction means M5, and an engine torque is thus reduced. When an acceleration slipping is estimated when traction control is not carried out, the throttle valve is closed by a stand-by control means M6. The amount of reduction by the torque reduction means is reduced by a torque reduction regulation means M7, when the traction control is started from a state where the stand-by control is carried out.
