IPC: C21D9/04
Filed: 1978-09-30
Abstract: PURPOSE:To give the required temperature gradient as far as the inmost portion, and to form fine pearlite structure as far as thorough depth, by forcibly cooling the bottom face of the rail head. CONSTITUTION:The portion lower than the face of bottom 1c of the head of the rail 1 is forcibly cooled by water injected from the water feed pipe 3 at the period ranging from the point just before the end of rapid heating to the point just after the end of this heating. The water after contacting the head bottom 1c falls down along the surfacial curve of the head bottom 1c, and along the stem 1d of the rail 1 naturally cooling this portion. As a result, the head bottom 1c is instantaneously cooled down to near the room temperature, and the heat of the hotter portion is radiated from this head bottom 1c, so that the temperature gradient in the head of the rail 1 hardly changes leaving a large temperature gradient in the inmost portion; hereby, the transformation into the fine pearlite structure becomes possible.

Title: Image reader
Inventor: MASUDA RYUICHI
IPC: G02B27/00
Filed: 1988-05-19
Abstract: PURPOSE:To obtain an image reader capable of performing both shading correction and the recognition of the outer frame of an object and is small in size and with high reliability by fixing an image pickup means at the reading position of the object, and enabling a non-diffusion plane for reading the outer frame and a diffusion plane for correcting sensitivity nonuniformity to be switched. CONSTITUTION:A white color plate 7 is positioned at a shading correction position A without placing the object, and light from a lamp 5 is irregularly reflected on the diffusion plane 7a of the white color plate 7 passing through a transparent glass plate 4, and diffused reflected light from the diffusion plane 7a passes the transparent glass plate 4 again, and is image-formed on an image sensor 1 by an image forming lens 3. The light read by the image sensor 1 is sent to a signal processor 6 as picture data including the nonuniformity of a light quantity or the sensitivity nonuniformity of the sensor itself, and the calculation of correction data is performed. Meanwhile, image light reflected on the object 2 at a part where the object 2 exists arrives at the image sensor 1 by turning the white color plate 7 to an outer frame reading position B. Since no light arrives at the image sensor 1 at the part where no object exists, it results that the part is read as a black part, and the outer frame of the object 2 can be recognized by the signal processor 6.

Title: Measuring device for irregularity of track
Inventor: KUBO SUSUMU
IPC: G01B7/34
Filed: 1980-09-03
Abstract: PURPOSE: To make the manufacture of a measuring device for irregularity of track which is high in both accuracy and reliability and is easy to calibrate possible by determining the signal corresponding to the difference  between the absolute displaycement of the longitudinal level surface of a vehicle body and the relative displacement of the longitudinal level surface between the vehicle body and an axle box and processing the same.   
     CONSTITUTION: The output of an accelerometer mounted to a vehicle body is double integrated and the absolute displacement rate thereof is obtained. Further, the relative displacement rate between the vehicle body and  an axle box is determined by using a relative longitudinal level surface displacement mechanism. Long wavelength components are removed from the signal corresponding to the difference between both by a high-pass  filter. For example the displacement of the longitudinal level surface of a rail 1 is the displacement of a wheel 8,  that is, an axle box 3, and is converted via arms 13, 15 to a converter 11, by which it is converted to an electric signal. The relative displacement rate between a vehicle body 2 and the rail 1 is determined by this signal.  The absolute displacement rate of the vehicle body is obtained by the double integration of the output of an  accelerometer 7 mounted to the floor 2' of the vechile body, and long wavelength components are removed  from the difference between both displacement rates, whereby the measurement of the irregularity of short wavelength longitudinal level surface of the rail is made possible.

Title: Valve device
Inventor: IZAKI AKIO
IPC: F16K17/04
Filed: 1980-09-03
Abstract: PURPOSE: To reduce a loss in a valve device even in a small size valve, which keeps it exit pressure constant, by virtually reducing the energizing pressure caused by spring force when the valve is opened.  
     CONSTITUTION: When the pressure in the upstream side 7 increases, the valve body 4 opens and a flow starts toward down stream side 8. Point of action P of the arm 6, which energizes the valve body 4 to close down, is shifted toward fulcrum 1 and the force the valve body 4 against the upstream side 7 becomes weak. Namely there is a tendency that virtual energizing pressure of spring 5 becomes weak, following the inclination of valve body 4 opening the valve. Such negative characteristic are determined by the relation between inclination of the swing valve 2 and the transfer of action point P. Therefore, if there is a tendency that characteristics become negative, there shall be such an effect that the deviation of pressure rise generated in the upstream side 7 in relation to the opening of the valve body 4 can be reduced.
