Title: Apparatus for track recognition
Inventor: TANZAWA TSUTOMU
IPC: G06T7/00
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To enable maintenance check of an apparatus at the stage of maintenance of a rolling stock without the need for new ground installation, reduction of operation cost for maintenance, and obtaining track information in real time. SOLUTION: The image of an object in the traveling direction of a rolling stock 1 is picked up with a stereoscopic camera 3.

Title: Method for adding impure element
Inventor: ODA MASASHI
IPC: H01L21/22
Filed: 1993-08-05
Abstract: PURPOSE:To rapidly and homogeneously add an impure element to a matrix by adding the impure element as its compound with an easily evaporable element and subsequently heating the mixture for removing the volatile element, when the impure element is added to the matrix such as a metal or a semiconductor. CONSTITUTION:A method for adding an additive containing an impure element to a solid matrix comprising a metal, a semiconductor, a non-oxide ceramic or an intermetallic compound is characterized by using the compound of the impure element with an element evaporating at a temperature below the melting point or decomposition point of the matrix as the additive. The compound is thermally treated together with the matrix at a temperature above the decomposition temperature of the compound to add the impure element to the matrix. When the matrix and the added impurity are e.g. a silicon-iron intermetallic compound and cobalt respectively, cobalt sulfide containing a desired amount of cobalt is first produced, and cobalt sulfide is mixed with the matrix. The mixture is heated at a temperature above the decomposition temperature of cobalt sulfide to evaporate and remove sulfur and to make the cobalt form homogeneous solution in the granules of the matrix.

Abstract: PURPOSE:To obtain excellent wow and flutter performance by providing a tape guide member on which a rotatable lever is erected between a capstan and a take-up reel and providing an elastic member set to a specified spring constant between the lever and a fixed post, and thereby making fluctuation of tension small. CONSTITUTION:A magnetic tape 1 is inserted between a capstan 2 and a pinch roller 3 and carried at a fixed speed, and rolled round a take-up reel 5 guided by a tape guide member 4 erected on a turning lever 13. A spring 16 is hung on the turning lever 13 from a fixed post 17, and the lever stops at a position balanced with tension of the tape when the tape runs. When tension of the tape becomes large, the lever turns counterclockwise around a supporting point, and when tension of the tape becomes weak, turning force acts clockwise, and the turning lever 13 and a tape member have spring effect. Accordingly, spring constant is so set by the spring 16 that the ratio or fluctuation coefficient of tension of the take-up tape at the time of resonance due to characteristic frequency of the vibration system and torque fluctuation frequency of a motor 8 becomes <=3.

Abstract: PURPOSE:To achieve high degree of integration, by providing electrodes which controls  the aligning directions of liquid crystals and liquid crystal molecules on a photodiode,  providing a constitution in which the polarization characteristic of the liquid crystal is  utilized, and discriminating light beams of two colors by only one photodiode. CONSTITUTION:A numeral 2 is the photodiode, 21 and 22 are electrodes, 21a and 22a  are filled insulating films having approximately the same thickness as that of the electrodes 21 and 22. A numeral 27 is the liquid crystal filling the photodiode 2. When a  voltage is not applied across the electrode 21, the molecule alignment in the liquid crystal is irregular b1, and both the color light (a) and color light (b) are transmitted.  When the voltage is applied, the molecules of the liquid crystal 27 are aligned b2, with  the direction of a major axis being aligned with the direction of the X-X' axis. Thus,  only the color light (a) is transmitted, but the color light (b) is not transmitted. This  action is the same in the X-Y plane at ZB. Therefore, the incident light to the photodiode is only the color light (a) when the voltage is absent across the electrode 22 and  the voltage is present across the electrode 21. The incident light is only the color light  (b) when the voltage is present across the electrode 22 and the voltage is absent across  the electrode 21. An electric signal corresponding to the amount of respective light is generated by the photodiode.
