A method for transferring data between electronic filing systems via a communications network and using facsimile communications protocol is disclosed. The method includes the step of adding codes corresponding to non-standardized terminal capability information into a session start command (CSS) of a facsimile communication protocol and sending the CSS to a receiving end electronic filing system. The non-standardized terminal capability information includes a code indicating that the sending system is an electronic filing system and the memory capacity of the sending system, etc.The method further includes the step of adding header information at the top of the communication data to be transmitted. The header information includes an identifier identifying whether or not the data to be transmitted corresponds to an image; if it corresponds to an image, the header information further includes the size and line density of the image, the compression method for the image, etc. In the receiving end electronic filing system, the header information is decoded and the receiving end electronic filing system is controlled to properly reconstruct the received information in accordance with the decoded header information. This method makes it possible to transmit specific images such as large size images or color image and code information, which otherwise cannot be transferred with facsimile communications protocol.

A hydrogen sensor comprising: a substrate, a detection film which is formed on the substrate and is composed of a rare earth metal, a protection film which is formed on the detection film and is a dispersion of hydrogen-permeable metal particles in a ceramic material, and a pair of electrodes which is formed apart on the protection film and are electrically connected with the detection film via the protection film. The hydrogen-permeable metal particles are Pd, Pt, Nb, V and Ta and the preferable content thereof is 20 to 70% by mass. It is preferred that the resistance of the protection film between the electrodes is 10 to 100,000 Ω and that the resistance of the detection film in the interelectrode direction is smaller than the resistance of the protection film in the interelectrode direction.

A rear wheel steer angle controlling apparatus for vehicles having steerable front and rear wheels, adapted for controlling the steer angle or rear wheels in response to the operation of the steering wheel for steering the front wheels. The speed with which the steering wheel is turned is detected and compared with a reference value which varies in accordance with changes in a physical amount related to the vehicle velocity. When the speed of operation of the steering wheel is larger than the reference value, a rear wheel steer angle is formed in the counter direction to the direction of the front wheel steer angle, so that the response to the steering input for turning the vehicle is improved. Conversely, when the speed of operation of the steering wheel is smaller than the reference value, a rear wheel steer angle is formed in the same direction as the front wheel steer angle, thus enhancing the stability of the vehicle running straight.

A shape of a boundary line between a forward view in a forward field of vision of a driver and a vehicle structural part that blocks a lower end of the forward view, i.e., the shape of a so-called visible edge of a vehicle hood, a shape of a visible edge of a vehicle instrument panel, or a shape of a top edge of a ceramic line formed at a windshield glass is made to be a curve. The curve may be expressed by hyperbolic function y2=Ax2+2Bx+C, where x is a depression angle, y is an azimuth angle, A is a constant expressed by a sum of a ratio of a distance between a viewpoint height and a roll axis with respect to the viewpoint height and a reciprocal of a product of a roll rate and the viewpoint height, B is a constant expressed by a reciprocal of the roll rate, and C is a constant expressed by the constant A, the constant B and a depression angle of a sight-line direction of a driver.
