Abstract: A floor vibration-damping apparatus damps a horizontal vibration of a floor based on an earthquake or the like. This apparatus comprises a movable supporting portion for supporting a floor structure with being free to move horizontally, and a damper working portion provided between said floor structure and a fixed floor.

Abstract: A floor vibration-damping apparatus damps a horizontal vibration of a floor based on an earthquake or the like. This apparatus comprises a movable supporting portion for supporting a floor with being free to move horizontally, and a damper working portion made by a combination of a viscous damper fixed to a restricted position of the floor and a plurality of spring mechanisms positioned radiately with respect to the restricted position.

Abstract: A motor scooter with an enlarged storage compartment that decreases the overall bulk and weight of the vehicle. The storage compartment is effectively sealed to prevent water or spilled fuel from leaking therein, yet provides easy access to the engine located beneath it for purposes of maintenance and inspection. The contents of the storage compartment are protected from the heat generated by the engine which is in close proximity by an insulating wall construction.

Abstract: A two wheel motorcycle of the scooter type employing a power unit with an engine mounted forwardly of the rear wheel, a power train extending rearwardly on one side of the rear wheel to couple the engine and the rear wheel and a muffler extending along the other side of the rear wheel. A carburetor is mounted above the power train and an air cleaner for that carburetor is mounted above the muffler. A connecting tube extends transversely of the vehicle between the air cleaner and the carburetor at a lcoation above and forwardly of the axis of the rear wheel.

Abstract: A power unit support structure of a motorcycle having a power unit and a frame structure including a support member having a rear end portion terminating in conjunction with the power unit which comprises an elongated swing member positioned between the power unit and the rear end portion of the frame structure and having at one end thereof pivotally connected with the power unit. A pivot support assembly is provided on the rear end portion of the frame structure for pivotally supporting the elongated swing member. A pair of rigid arms is provided each of which is fastened onto the swing member at one end thereof. The rigid arms are associated at the other ends thereof with the rear end portion of the frame structure by way of damper means for dampening the swing motions of the swing member.

Abstract: A power-unit support structure of a motorcycle having a power unit and a frame structure including a tubular member having a hollow rear end portion, comprising a rigid bracket member secured to the tubular member and positioned in the vicinity of the rear end portion of the tubular member, a first pivot assembly positioned between the power unit and the tubular member and pivotally movable about an axis fixed with respect to the frame structure, a second pivot assembly mounted on the power unit and pivotally movable about an axis fixed with respect to the frame structure and parallel with the axis of pivotal motion of the first pivot assembly, rigid connecting members providing connection between the first and second pivot assemblies, a damper assembly rigidly connected to the first pivot assembly and elastically engaging the rear end portion of the tubular member.

Abstract: A fluorescent display device comprising a display tube section having a plurality of phosphur-coated anodes arranged in the form of a matrix and electrically connected together on a row-by-row basis, the anodes being grouped into a plurality of groups each having a plurality of anodes, primary control electrodes provided opposite to the anodes, one for each group, secondary control electrodes provided between the primary control electrodes and the anodes, one for each column, the groups being grouped into a plurality of blocks each containing at least two groups, and the secondary control electrodes being provided so that those disposed opposite to the corresponding columns of the blocks are electrically connected together by control-electrode wires.

Abstract: A fluorescent display device having at least a filamentary cathode for emitting electrons, pattern display sections each coated with fluorescent material, a plurality of control electrodes electrically independent of one another provided opposite to the pattern display sections respectively, the anodes and control electrodes being selectively given drive signals thereby to make the electrons emitted from the filamentary cathode impinge on the anodes so as to display characters, numerals, graphic forms and the like on the pattern display sections, and a plurality of auxiliary electrodes provided at or above and in the vicinity of gaps between the control electrodes respectively and at all times kept at a positive potential with respect to the filamentary cathode so that the mutual influence of the control electrodes may be intercepted.

Abstract: A fluorescent display device having pattern display sections each composed of phosphor-coated anodes arranged in the form of a matrix, at least a filament for emitting electrons when heated, the anodes being selectively bombarded with electrons emitted from the cathode to produce a visual display, position-selecting grids provided between the filament and the pattern display sections, column-selecting grids or row-selecting grids provided opposite to the columns or rows of the anodes, and a frame member provided, on its surface facing the filament, with the position-selecting grids and on its surface facing the pattern display section with the column-selecting grids or the row-selecting grids, the frame member being made of insulating material at least where necessary. With the provision of the frame member, the device of the present invention can be assembled easily, securely and correctly, and can produce a high-quality display.

Abstract: A luminescent display device for analog display having segment anodes provided linearly on a substrate and each coated with a luminescent material layer, the segment anodes being selectively given an anode voltage according to information inputted, a filament provided above the segment anodes for emitting thermions when heated, the thermions selectively impinging on the segment anodes so as to make them emit light, and conductors each provided above and opposite to a gap existing between every two adjacent segment anodes, the conductors being kept positive with respect to the filament. The conductors provide a control for the anode field which prevents the "shade" phenomenon from occurring on the anodes.

Abstract: A multi-column fluorescent display tube having a filament cathode provided opposite to a plurality of fluorescent display sections, which comprises at least a filament damper made of an insulating material low in thermal conductivity and having contact sections for supporting and stretching the filament cathode under tension at the middle portion of the filament cathode, and filament damper supporters so formed that it can prevent electrification of the surface of the filament damper.

Abstract: An artificial land structure framework minimizing the destruction of nature such as hills and plants.The framework has a plurality of beam members connected with each other to form a number of laterally disposed rectangular three-dimensional spaces, and artificial lands are stepwise provided along the diagonal lines of the three-dimensional spaces. The framework is of a truss structure with flexibility for modification, extension and reduction, and being able to have any desired number of layers of the artificial lands constructed on an inclined or flat ground.
