This feeder line includes: a plate-shaped dielectric substrate; a first conductor pattern dividing a first surface of the dielectric substrate into a first area and a second area; a first-area ground conductor pattern formed in the first area; a second-area ground conductor pattern formed in the second area; a second-surface ground conductor pattern formed on a second surface; a second conductor pattern connecting the first conductor pattern and one or both of the first-area ground conductor pattern and the second-area ground conductor pattern; a plurality of conductors and connecting between the second-surface ground conductor pattern, and the first-area ground conductor pattern and the second-area ground conductor pattern; and a conductive member connecting the first-area ground conductor pattern and the second-area ground conductor pattern. A length of the second conductor pattern is an odd multiple of ¼ of a wavelength of a signal propagating through the first conductor pattern.

Feeder line and antenna device using same

To provide a laser distance measuring apparatus which can increase the measurement frequency per unit time by suppressing the increase in the data amount expressing the measurement time, while ensuring the distance measurement precision and the measurable distance. A laser distance measuring apparatus measures, with a time resolution, a light receiving time which is a time from a time point when the laser beam generating unit emits the laser beam to a time point when the light receiving unit outputs the light receiving signal; calculates an object distance which is a distance to the object, based on the measurement result of the light receiving time by the time measuring device; and changes the time resolution of the time measuring device used for calculation of the object distance, based on detection information.

Laser distance measuring apparatus

In a current detection apparatus, one or more first plate portions, one or more second plate portions, and one or more third plate portions of one or more magnetic shields are opposed to side surfaces of the one or more protrusions. The one or more protrusions, the one or more magnetic field detection elements, and one or more conductive members are respectively surrounded by the one or more magnetic shields, respectively. Consequently, the current detection apparatus is downsized and has high current detection accuracy.
