Abstract: PROBLEM TO BE SOLVED: To enhance breaking performance by preventing the concentration of an arc on an electrode central part by a longitudinal magnetic field. SOLUTION: An annular coil support ring 5 is brazed to the tips of a movable side current carrying shaft 6 and a fixed side current-carrying shaft through a coil electrode 14 and a reinforcing member 18. In a central part of this coil support ring 5, a central coil 7 is housed in the axial direction inside the support ring 5. Outer peripheral part coils 3 manufactured by a copper material are arranged at intervals of 60 deg. around this central coil 7. An electrode plate 2 is superposed on the further tips of these outer peripheral part coils 3. A contact 1 is superposed on the outside surface side of this electrode plate 2, and these contact 1 and electrode plate 2 and outer peripheral part coils 3 and coil support ring 5 are brazed to each other.  A carried current of the central coil 7 is restrained to about 1/4 of an electric current flowing to the outer peripheral part coils 3, and a synthetic magnetic filed by the coil electrode 14 is gradually increased to an outer peripheral part from the axis, and is almost doubled in the outer peripheral part.

Title: Automatic train operating method
Inventor: AOYAMA TAKEO
IPC: B60L15/40
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To improve comfort of the passengers in a train by changing power running or braking step by the amount that compensate the difference between the actual acceleration/deceleration of the train and the acceleration/deceleration calculated from the distance to a target stop point, train speed, the angle of inclination of the passengers and angular velocity. SOLUTION: This automatic operating device 1 starts monitoring the pattern of a target deceleration when the signal that indicates that a train has entered a fixed stop section is inputted from a point signal receiving device 3. The position, speed and acceleration/deceleration of the train are measured with a signal from a speed measuring device 4 and the angle of inclination of the passengers and angular velocity are measured with a signal from an angle measuring device 9.  If the train speed exceeds a target deceleration, the calculation of the control acceleration/deceleration is started to obtain the difference between the actual acceleration/deceleration of the train and the control acceleration/deceleration, to change power running or braking steps and to perform the control with this new step commands Thus, the control can be performed in such a way that the angle of inclination of the passengers does not become larger so that the fall of the passengers can be prevented and the comfort of the passengers in the train can be improved.

Title: Internal pressure holding device for air mat
Inventor: YAMASHITA KAORU
IPC: G05D16/20
Filed: 1991-09-13
Abstract: PURPOSE:To decrease the power consumption at the time holding internal pressure of an air mat. CONSTITUTION:Pressurizing/depressurizing means 4 having solenoid valves 12 for pressurizing/depressurizing air pressure in an air tube are driven by a battery 5. The solenoid valves 12 are controlled by two stages of a working voltage and a holding voltage of the solenoid valves 12 being smaller than the working voltage. After the solenoid valves 12 are turned off in pressurizing/ depressurizing operations, whether they become set pressure or not is confirmed and when they do not become the set pressure, the pressurizing/depressurizing operations are repeated by turning on the solenoid valves 12. With respect to the holding voltage controlled by a control means, in the case external force exceeding a prescribed value works on an air mat main body 1, there is possibility that such a malfunction as the solenoid valves 12 are closed is generated, but in a state that the air mat body stands still, it is set to a voltage by which the valves are not closed.

Filed: 1994-09-01
Abstract: PURPOSE: To generate a good apperance without causing change in the diameter of a hinge pin inerting hole by furnishing a lid with a contacting part with which the lid is shifted and energized through an elastic deformation of a hinge pin at the time the lid is to be shut. CONSTITUTION: When a lid 5 is shut, a projection 4 installed in a recess 2 is contacted with a projection 6 of the lid 5 from the rear end wall of a vessel body 1, and also a pair of projections 8 installed on the lid undersurface are contacted with the oversurface of the vessel body 1. Accordingly, the lid 5 is forcedly moved back upward, and the axis of a hinge pin inserting hole 7 is put in eccentricity back upward to another hinge pin inserting hole 3. As a result, a hinge pin 9 inserted through the holes 3, 7 makes elastic deformation so that the lid 5 is forcedly moved back upward and energized.  When a hook 13 on the lid 5 is set off from a lid opening piece 11 from a projection 12 for hook detention provided on the vessel body 1, the lid 5 is automatically opened by the resilient force of the hinge pin 9 in elastic deformation back upward, which eliminates necessity for any change in the diameter of the pin inserting hole, presents a fine appearance, and allows simplifying the die used.

Filed: 1986-10-03
Abstract: PURPOSE:To remove difficulty due to a backlash by keeping one gear train in the clockwise contact relation of tooth surfaces, and another one in the counterclockwise contact relation of tooth surfaces. CONSTITUTION:A gear train extending from an input gear 2 to a pinion gear 7 and a large gear 3 through one intermediate gear 5 is kept in the meshing relation of tooth surfaces for transmitting power in a clockwise, direction C, and a gear train extending from the input gear 2 to a pinion gear 7' and the large gear 3 through another intermediate gear 5' is kept in the meshing relation of tooth surfaces for transmitting the power in a counterclockwise direction R. When the one gear train operates as a power transmission system, the another gear train can be made to followingly rotate with the tooth surfaces on an opposite side being mutually only in contact. Consequently, even in the power transmission system for driving the large gear 3 by the pinion gears 7, 7', the occurrence of time-lag due to a backlash can be prevented in changing over the gear train into its reverse rotation.
