Title: Vehicle track and vehicle
Inventor: SHIRATORI KUSUO
IPC: B61C13/06
Filed: 1989-12-02
Abstract: PURPOSE:To lessen the track laydown area as much as practicable and offer the land under the track to effective utilization by furnishing a rail bearing mechanism, consisting of rail ropes to be tied by truss structure, on a horizontal member whose two ends are fixed horizontally to a prop fixing part. CONSTITUTION:A plurality of props 1 are arranged at a certain spacing, and a plurality of ring-shaped frames 2 are installed in continuity tunnel-formed at a certain spacing. A thick and highly strong main rail wire rope and an aux. rail wire rope 4, which is thin and capable of tightening at level substantially, are stretched between the props 1, and a member 6 as a rigid body is set over between the two ropes to form a truss structure. This enables supporting approx. at level the rail 5 by the aux. rail wire rope 4 which is spread approx. horizontally. This enables lessening light blocking for the land etc. under the rail and also suppression of the land for laydown of the track, which permits effective utilization of spaces for ex. on the roof of building, over the forest, etc.

Title: Receptacle type contact
Inventor: GEORUKU YOOZEFU BARUTOTSUSHIYU
IPC: H01R4/18
Filed: 1990-11-21
Abstract: PURPOSE: To provide an electric receptacle which has high contact pressure and whose inserting force is low by arranging a central part whose base part extends in the shaft direction and which is connected to the base part on the front end and the rear end and whose front end part inclines to the free end side of an elastic arm. CONSTITUTION: A fitting front end part 4 contains a base part 10, and has an integral side wall 12 rising from this base part 10. This side wall 12 is bent in the inverse (downward) direction after rising, and forms a curved surface part 14, and this curved surface part 14 forms an elastic arm part 16 proceeding to the base part 10, and the tip of this elastic arm part 16 is again bent upward, and forms an arc-shaped contact part 18. Then, when a tab type contact is inserted into a receptacle type contact 2, a central part 22 is made eccentric downward, and enables the tab type contact to contact with a contact surface 38. As a result, inserting force is reduced since it runs along the surfaces 38 and 40 forming an almost line contact surface. Therefore, a receptacle type contact whose inserting force is extremely low and contact pressure is high, can be obtained.

Title: Grain charging device of grain analyzer
Inventor: MORI TAIICHI
IPC: G01N21/85
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To make compact and easy to carry and reduce cost by rotating a funnel freely rotatably set at the upper part of a storing box accompanying the rotation of a part of members of the storing box, and increasing the charg ing area. SOLUTION: The charging funnel 3 consists of a main body funnel 12 and an opening/closing funnel 13 which can be freely rotated, opened and closed. The funnel 13 is set to a rotary shaft 14 supported to a right and a left wall plates of the main body funnel 12. A torque spring 15 is fitted to the rotary shaft 14. When a storing lid 10 of a storing box 2 is opened, a stopper 13a at an upper part of the funnel 13 automatically rotates forward owing to the torque spring 15 until the stopper 13a butts against a stopper pin 12a at an upper part of the main body funnel 12, and is accordingly opened. As a result, a throw-in area for grains is increased. When the storing lid 10 is closed, the funnel 13 is pressed by the storing lid 10 and automatically rotates rearward into a closed state.  Since the funnel 13 is adapted to rotate, a fitting space therefor can be small, so that a grain analyzer can be compact and easy to carry. Moreover, the cost can be reduced.

Filed: 1986-12-27
Abstract: PURPOSE:To improve sensitivity in detecting by a method wherein two or more superconducting filaments are parallelly buried in a metal matrix and slicing is accomplished along the direction squarely crossing the length of the filaments for the construction of Josephson elements. CONSTITUTION:Two or more superconducting filaments 2 are buried in a metal matrix 1 in a roughly parallel configuration, so separated from each other that there will be an Josephson effect. Slicing is accomplished along the direction squarely crossing the length of the filaments 2 for the construction of Josephson elements. One end face of a filament 2 is flush with the front surface 3 of a device while the other end face of said filament 2 is flush with the rear surface 4 of the device. On the rear side 4, there are conductive circuits 5 and 6 formed in a lattice. A longitudinal circuit 6 is in contact with the end face of a filament 2 that is under the circuit at locations 7 where there is not an insulating film while the lateral circuit 5 being isolated from the circuit 6 by the insulating film is in contact with the end face of the filament 2 that is under the circuit at locations 8. In this way, the number of Josephson junctions may be increased, which contributes to the improvement on sensitivity in detecting.

Title: Oscillation actuator
Inventor: KOBAYASHI MINA
IPC: H02N2/00
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To avoid seizure surely. SOLUTION: A face 22 coming into contact with the pressure contact parts 13a, 13b at driving power take-out sections 11a, 11b only when oscillation of an oscillator 10A stops is provided contiguously to the motion area 21 of the oscillator in a relative motion member 20 on same plane as the motion area 21. Consequently, the oscillator 10A passes through the motion area 21 of the oscillator in the relative motion member 20 (in case of self-advancing) or drives the oscillator (in case of fixed oscillator) when the oscillator 10A is driven and the pressure contact parts 13a, 13b at the driving power take-out sections 11a, 11b come into pressure contact with the face 22 disposed contiguously to the motion area of the relative motion member 20 on same plane as the motion area when the oscillator 10A is stopped.  Since abrasion powder scarcely adhere to the contacting face 22, seizure can be avoided surely upon stoppage of the oscillator.
