IPC: G08G1/0969
Filed: 1986-08-23
Abstract: PURPOSE:To achieve a movement of an automobile or the like accurately and quickly, by indicating optimum path to an operator timely according to the movement of a moving body based on map information of a map information recording medium prepared by a map information preparing system. CONSTITUTION:A path model is made almost identical to a real road and an error detector section detects errors in the movement between the path model and a moving object model to make the operation of a moving mechanism section standard with a moving mechanism operating section. Then, the operation value of the moving mechanism section is outputted as movement of a moving object with a moving property section. A path guide model learns a plurality of optimum paths which have any position as current location and all other positions set for the destination and also names of land and object available as marking point in various districts and transmits, to an operator model, necessary information timely from announcement and map models. A mapping device processes various numerals and information and records map information on a recording medium. This enables accurate and efficient movement of an automobile or the like.

Title: Semiconductor device
Inventor: KATO KOJI
IPC: H01L21/822
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the area of a capacitor without reducing its capacitance and prevent increase in the number of processes for the capacitor and eliminate asymmetric capacitor characteristics by connecting at least one of two electrodes sandwiching a dielectric between to an interconnection layer through a buried plug. SOLUTION: Since a side wall of a dielectric 110 is to be brought into contact with electrodes of a capacitor, it is desired that the dielectric 110 is formed near a buried plug which connects the electrode of the capacitor to an interconnection layer or to a diffusion layer. A film 111 which becomes the electrodes for the capacitor is formed by sputtering platinum and then is etched over the entire surface by anisotropic etching. For example, when the film 111 is etched over the entire surface by the beam incidence in the direction vertical to a semiconductor substrate 101, it becomes an anisotropic etching. Therefore, a side wall of the dielectric 110 is not etched and electrodes 112 and 113 remain, at least one of which is self-alignedly connected to a buried plug 109 near the dielectric.

Abstract: PURPOSE: To insure comfortableness at moderately braking and to maintain a stable body posture at suddenly braking by regulating damping force according to actual braking force based on output of a braking force sensor. CONSTITUTION: Brake callipers 7 are supported with a front fork 1A through a link 3A, and elastic bodies 5, 6 compressed between the link 3A and the front fork 1A at braking are provided.

At moderately braking, output of the braking force sensor 10 is small, generated pressure side damping force is low, and hence favorable comfortableness is insured. At suddenly braking, output of the braking forces is large, high damping force is generated, and hence a vehicle body posture is surely prevented from changing accompanying the sudden brake.
