摘要： PURPOSE:To enable recording of high resolution to be performed by strengthening magnetic combination, with toner, by a method wherein by combination of a photoetching method and a plating method, a group of recording electrode of thick film thickness and high density, composed of conductive materials is formed on an insulating substrate, and non-conductive magnetic materials are filled in spaces thereof. CONSTITUTION:A thin film of a metal layer easy to be oxidized is formed on an insulating substrate 3 and, for instance, copper as a ground layer 5 is applied to all surfaces thereof. After applying photo resist in relation to photosensitive resin, a fine line pattern 6 is formed by photoetching. Then, conductive magnetic materials are applied to spaces among the fine line pattern on the ground layer 5 by a plating method and conductive magnetic electrodes 1 are formed. Thereafter, a fine line pattern other than said conductive magnetic electrodes 1 is removed by etching of the ground layer 5 thereunder and the metal layer 4, and non-conductive magnetic powder is mixed with organic binder and filled by coating in spaces among many conductive magnetic electrodes 1 newly formed to form non-conductive magnetic materials 2.

摘要： PROBLEM TO BE SOLVED: To reduce vibration transmitted from a truck to a car body via an actuator and to improve comfortableness. SOLUTION: In a rolling stock, an actuator 5 is disposed between the car body 1 and a truck 2, and is driven by working fluid supplied from a working fluid supplying device 13, and a car body tilting operation is performed. The rolling stock comprises a control valve 12 for controlling direction and flow rate of the working fluid to the actuator 5 and a controller 14 for controlling the control valve. When a command of performing the car body tilting operation is not issued from the controller 14 during running a vehicle, the control valve 12 is controlled so as to open a flow channel for making the working fluid in the actuator 5 flow out of the actuator 5.

摘要： PROBLEM TO BE SOLVED: To realize misfire detection by means of a simple operation. SOLUTION: At every explosion in each cylinder, a parameter indicating a rotating state of a crankshaft is computed from an interval in a pulse signal from a crank angle sensor. A specific frequency component is extracted from a time series of the rotating state indicating parameters. The specific frequency component is stored retroactively over the length of the period of the specific frequency or an integral multiple thereof. The intensity of the specific frequency is calculated from the stored specific frequency components, and a cylinder exploding when the stored specific frequency components satisfy a given magnitude relation is determined. A misfiring cylinder is located from the cylinder exploding when the specific frequency components satisfy the given magnitude relation and the intensity of the specific frequency.

摘要： PROBLEM TO BE SOLVED: To improve comfortableness by enlarging a body inclination angle at the time of passing through a curve. SOLUTION: A link torsion bar 10 formed of a torsion bar 12, levers 13L, 13R and links 11L, 11R is arranged between a rolling stock body 1 and a bogie frame 2. In such a structure, when a centrifugal force acts, the body 1 is displaced in a roll angle according to transverse displacement, and an air spring 7R on an outer track side of the curve extends and an air spring 7R on an inner track side of the curve contracts. A control device 23 refers to track information data 24 and grasps a present traveling position, and opens a selector valve 22 for communicating the right and left air springs in a state of traveling on a transition curve wherein an inclination operation is performed. In this case, since a restitutive force does not act, the body inclination angle is enlarged and the comfortableness can be improved. In a state of traveling on a track wherein the inclination operation is not performed, the selector valve 22 is closed for dividing the right and left air springs, and the restitutive force and damping force of the air springs are applied. Thereby vibration is damped and the comfortableness can be improved.

摘要： PROBLEM TO BE SOLVED: To provide an automatic braking device equipped with a barometric electronic control servo assistor, capable of operating braking force smoothly. SOLUTION: This braking device is provided with a valve mechanism operated electromagnetically; two compartments of which pressure is controlled by the valve mechanism; an output axis which advances/retreats by differential pressure between the two compartments; the electronic control servo assistor which outputs by the output axis; a fluid pressure detecting means for detecting brake fluid pressure; a target brake pressure output means for outputting target brake fluid pressure; and a controller for controlling current which electromagnetically drives the valve mechanism of the electronic control servo assistor by taking respective outputs of the fluid pressure detecting means and the target brake fluid outputting means as inputs. In this controller, a deviation between the target brake fluid pressure and the detected brake fluid pressure is calculated to control the current using the obtained deviation and control gain which is preset in advance so as to correspond to the deviation, and the control gain is set so as to decrease as the deviation increases.
