Abstract: PROBLEM TO BE SOLVED: To prevent the characteristics of an antenna element from being degraded by providing a coupling element to be coupled electrically with the antenna element without contact, when housing the antenna element and a correction circuit for correcting the impedance of the antenna element. SOLUTION: A coupling element 6 constituting of a stick-shaped conductor is installed in a state of no contact with a rear antenna element terminal part 4b, so as not to locate any electric circuit or electrical component between the rear antenna element terminal part 4b and the coupling element 6 in the rear terminal direction of an antenna element 4 as seen from a power feeding point 5. In addition, a correction circuit 7 is coupled with the coupling element 6 at an electric node 8 at all times. In this case, an AC electric circuit is composed of the rear antenna element terminal part 4b, a coupling element 6 and a correction circuit 7 at the time of housing. Therefore, when the impedance of the rear antenna element terminal part 4b is enlarged, a current hardly flows through and if the correction circuit 4 is set so that the impedance can be infinite or thereabouts, almost no current flows from the power feeding point 5 to the rear antenna element terminal part 4b.

Filed: 1992-03-25
Abstract: PURPOSE:To detect a printing density with a high accuracy and judge whether the number of black dots is large or small by providing a judging means which detects a printing density intrinsic to a device from a judged value of an accumulated value of relative data obtained from a black dot count calculation means. CONSTITUTION:Printing data imparted from the external is printed on a medium by a printing part 1.

The number of black dots in the separated image data is counted by a black dot counting part 4. The black dot count data is stored in a storage part 5. As long as the amount of the stored data is small, a printing density is judged by a judging part 6 by comparing the data stored in the storage part 5 with predetermined data. However, when the data amount increases to a fixed value or more, a relative relation between the disribution of said data and a printing data amount is judged by the juding part 6 for detecting a printing density.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the practical effect of the route guidance by permitting a forced guidance in the case where no guidance is made at a spontaneous guide timing because of a short distance between intersections under guidance. SOLUTION: A specified guidance is made at a spontaneous guide timing when the distance from an intersection under guidance is a specified value a0. When no spontaneous guide timing is generated because of a short distance between own vehicle position and an expected intersection B under guidance next to a first passed intersection A under guidance, a guide timing is forcibly generated to guide. Concretely, just after passing the first intersection A, the vehicle is guided to at least the second intersection B under guidance and also, in this case, to a third intersection C under guidance. Because of also a short distance between the second and third intersections B, C under guidance, the vehicle is guided to the third intersection C just after passing the second intersection B.

Abstract: PURPOSE:To vary the converging position of the laser beam to the radius direction or the direction of tangential line of a recording track for a controller for light converging position, by adding an objective lens at an end of a flection-type piezoelectric element. CONSTITUTION:Figures 15 and 15' show the baring parts, and the outer circumference part of a bearing 17 having a shaft-shaped member 16 in its inside is adhered to an end of flexion-type piezoelectric elements 7 and 7' each.
