摘要： PROBLEM TO BE SOLVED: To solve the following problems wherein stop position detection accuracy is poor and a travel amount from a stop position to the opposite direction is limited when a train travel distance from a wayside coil position is long; and a predetermined speed or below cannot be detected during train stop determination, and time lag due to several-second waiting time deteriorates train operational density during rush hour.
SOLUTION: A train stop detection system includes a train-mounted image pickup section for periodically photographing image signals; a detection object information retention section for retaining template images of detected objects in individual stations and offset distances from the respective detected objects to stop positions; a train position detection section for detecting the detected object from the image taken by the image pickup section and then detecting a train position based on a distance to the detected object; a travel speed detection section for detecting a train travel speed from the image taken by the image pickup section; and a train stop determination section for determining whether a train stops at a prescribed stop position by using the results of the train position detection section and the travel speed detection section.

摘要： PROBLEM TO BE SOLVED: To prevent erroneous communication outside the specified communication area. SOLUTION: The method is provided with a calculating means for calculating the position of a mobile station by receiving an electric wave transmitted from a mobile station and detecting the incoming direction, a decision means for deciding whether or not the mobile station position exists within the specified area, and a means for controlling communication with the mobile station by using the decision result. Thus, by using a plural pieces of information on the mobile station position obtained through the radio communication, it is surely decided whether outside or inside the area the mobile station is located. When the mobile station position is decided to be inside the specified area, data to be transmitted next are transmitted to the mobile station. On the other hand, when the position is decided to be outside the specified area, re-send request processing of the data is made to the mobile station; and when the mobile station position is decided to be outside the specified area even after the decision is made for the defined number of times, the communication is decided to be abnormal one and it is canceled.

摘要： PROBLEM TO BE SOLVED: To provide a technique of taking measures to improve a radio wave propagating environment composed of the road surface and constructions such as buildings etc. as needed, by analyzing and evaluating propagating characteristics of radio waves transmitted from a transmitting station in this environment. SOLUTION: The radio wave environment evaluating method comprises a step of calculating the propagation paths between a transmitting and receiving points based on an inputted radio wave propagating environment model, calculating the reception powers, comparing the reception power per path with a threshold to decide whether or not unwanted radio waves are incoming to outside a desired communication range, calculating a required guard range for suppressing unwanted waves, and outputting the result on a display. This analyzes the propagation characteristics of radio waves transmitted from a base station to indicate countermeasure contents for suppressing radio waves from leaking outside the desired communication range, thereby efficiently designing the improvement of the radio wave propagating environment.

摘要： PROBLEM TO BE SOLVED: To eliminate an omission of toll collection from the user of an illegal vehicle by precisely deciding the illegal vehicle passing through an automatic toll collection system. SOLUTION: The detection result of a passing vehicle obtained by an image processing part is contrasted with stored information on the position where an on-vehicle machine is installed to predict the positions of on-vehicle machines of each passing vehicle, the position of an actual on-vehicle machine is calculated from the mentioned stored position information and the sending source direction of a radio wave obtained by radio communication, and the predicted position is contracted with the actual position to decide whether or not an on-vehicle machine is mounted on the passing vehicle.

摘要： PROBLEM TO BE SOLVED: To determine the three-dimensional position of a moving body by providing at least one array antenna with spatial arrival angle detecting sensitivity in a vertical direction in addition to at least two array antennas with spatial arrival angle detecting sensitivity in a horizontal direction. SOLUTION: An action acquisition object 501 is an actor performing action to be acquired, for instance. Transmitter-receiver bodies 301 are fixed to a head, a waist, elbows, knees and the like and different individual numbers are allocated and previously held in a joint layout memory 163. Phased array antennas 101 are arranged in such a way as to surround the action acquisition object 501. A transmitter-receiver position tracking processor 161 acquires the individual numbers and three-dimensional positions of the respective transmitter- receiver bodies 301 in time series. The information is successively stored in an external storage device 162. The locus of the transmitter-receiver is applied to the corresponding parts of a computer graphics model of the action acquisition object 501 on the basis of layout registered in the joint layout memory 163, so as to be able to reproduce the action of the action acquisition object 501.

摘要： PURPOSE: To minimize the stress developed in case of installation and to improve the quality of piping by finding the variation quantities of the directions of error vectors that minimize a composite vector in magnitude, and outputting the variation quantities as the quantities of rotation of the piping corresponding to the error vectors. CONSTITUTION: When pipes 1 and 2 are installed between equipments 1 and 2 in the angle state shown in the figure (b), errors of the pipes 1 and 2 are cumulatively added as they are. For the purpose, when proper angles on the axes of the pipes 1 and 2 are selected, the errors can be prevented from being accumulated. Namely, when the pipe 2 is installed while rotated on the axis by 180 deg. on the basis of the state in the figure (b), the errors of the pipes cancel each other and deflection is eliminated on the whole. Thus, the errors are minimized to suppress the generation of the stress as much as possible. When the number of pipes is large, it is difficult to determine proper angles, pipe by pipe, but the determination of the angles of respective pipes whose errors become minimum is automated to facilitate the determination.

摘要： PURPOSE:To prevent generation of bubbles in a glass adhered part by mounting a base and a cap by glass-adhering a central part of a cap or base mounting surface to a glass layer formed at the central part of the mounting surface to be high and sealing a semiconductor element. CONSTITUTION:A cap 1 is formed in a rectangular shape, and a central part is so coated to be high along a frame as to form three sealing glass layers 2a-2c of a mounting surface 2 of the cap 1 side. On the other hand, a base 3 is formed similarly to the cap 1 in a rectangular shape, and a mounting surface 4 of the base 3 side is formed of glass equivalent to that of the cap mounting surface 2. The cap 1 and the base 3 are positioned, both mounting surfaces 2, 4 are raised to a temperature for melting in a sealing furnace, and adhered to seal a semiconductor element 6 therein. Thus, reliability can be improved without generating bubbles in a glass-adhered part.
