Abstract: Provided is a folding electric bicycle comprising a front frame section; a rear frame section comprising two bent arms individually having one end pivotably coupled to an axle passed rear wheel, and two auxiliary wheels rotatably mounted in open ends of the bent arms; a crossbar comprising a front end and a rear end pivotably coupled to the front and rear frame sections respectively; a latch detachably interconnected the crossbar and the rear frame section; and a down tube interconnected the front and rear frame sections. The rear frame section can either retract toward the front frame section about the unfastened latch for folding or extend from the front frame section about the unfastened latch for extending. The auxiliary wheels are either disposed above the ground when the bicycle is ready or rotatable and contact with the ground when the bicycle is folded for facilitating moving.

The display panel assembly comprises a machine case. The machine casing comprises a cartridge seat; a circuit substrate; a button panel; and a mask plate. In assembly, the mask plate covers upon the button panel so that the button holes are aligned to the buttons on the button sets. Then the mask plate covers upon the cartridge seat; then a plurality of screws passes through the through holes and the via holes of the vertical folding sheets, and the via holes of the circuit substrate so as to lock the cartridge seat, circuit substrate, button panel and mask plate together.

Abstract: The present invention provides a structure of an evaporation region of an absorption diffusion type refrigerating circulation. The refrigerating circulation comprises a generator, a rectifier, a condenser, an evaporator, a concentrated ammonia aqueous solution tank, and an absorber. An ammonia liquid pipe and a hydrogen pipe are arranged in a pipeline of the evaporator. The evaporator at the evaporation region has a simple shape and structure, and can be processed easily, hence saving the space thereof. Because the ammonia liquid pipe and the hydrogen pipe are arranged in the evaporator, the effect of heat exchange thereof is better, and the refrigerating temperature is lower.

Abstract: An absorption diffusion type refrigerating structure comprises a generator, a rectifier, a condenser, an evaporator, a concentrated ammonia aqueous solution tank, and an absorber. The absorber is vertical. A spiral device is disposed in the absorber to lengthen the flow path of diluted ammonia aqueous solution, to extend the time of diluted ammonia aqueous solution in the absorber, and to expand the reaction area of diluted ammonia solution in the absorber, thereby reducing the whole weight, shrinking the volume, and enhancing the refrigerating speed. An ammonia liquid pipe and a hydrogen pipe are arranged in the evaporator. The evaporator has a simple and symmetrical shape, and can be processed and assembled easily, hence saving the space thereof. Moreover, because the ammonia liquid pipe and the hydrogen pipe are arranged in the evaporator, the effect of heat exchange thereof is better, and the refrigerating temperature is lower.

Abstract: A water-repellent coating has tetrafluoroethylene resin powder, silicone resin binder, and organic solvent. The tetrafluoroethylene resin powder has a ratio of the peak absorbance at 1,800 cm−1 to the peak absorbance at 500 cm−1 of 0.0001 to 0.05 exclusive. A coating film is formed by applying such a coating on a substrate. The coating has the properties of high water repellency, excellent anti-ice-coating, excellent anti-snow-coating, and so on, in spite of not having a large amount of fluororesin powder. In addition, the coating of film keeps the water repellency regardless of whether the coating film is immersed into water for a long time.

Abstract: The present invention proposes a concentrated ammonia aqueous solution tank used in an absorption diffusion type refrigerating equipment. The present invention is characterized in that a capillary tissue is placed in the concentrated ammonia aqueous solution tank. The capillary tissue is formed by bending knitted metal nets or is integrally formed by means of sintering. Thereby, additional surface area of absorption reaction can be increased, and the volume and weight of the original absorber can be reduced, hence increasing refrigerating speed and reducing refrigerating temperature.

Abstract: An occupant-operated motorized vehicle is provided having a motorized front wheel assembly. The vehicle is further provided with an operator controlled lifting structure which aides the occupant in coming to a standing position. The lifting structure includes a linear actuator that is coupled to a clevis, which is in turn coupled to a shaft. Activation of the actuator causes the clevis and therefore the shaft to rotate. Attached to each end of the shaft is a lift lever that extends rearwardly away from the shaft. The end of the lever not attached to the shaft are equipped to be coupled to a support sling that is used to support the occupant and raise the occupant to a standing position. The vehicle is further equipped with a seat to accommodate the occupant in an initial seated position, and at any time that the occupant desires to be in a seated position.

Abstract: A shock absorber for a vehicle is provided with an elongated rod which is longitudinally displaceable with respect to a carrier which supports at least one frictional rod engagement member for producing a rod travel retardation force. The rod engagement member is arranged to apply a lateral force to the rod, which lateral force is translated into the rod travel retardation force to smoothly and quickly control the motion of the rod between first and second positions. The frictional rod engagement member can be urged against a rod in various ways, including compression of a resilient or elastic force exerting component, such as a wire-wound spring. The combination of the force exerting components and the frictional member can be configured to apply retardation forces to the rod which have preselectable damping characteristics. In a featured embodiment of the invention, the resilient force exerting component is itself damped by contact with the frictional rod engagement member.

Abstract: A resilient element shock absorber having a casing and a movable rod extending into a bore in the casing. Two bushings are slidably disposed in the bore, and a resilient structure is disposed between the bushings. Upon displacement of the rod in either direction from its neutral position, one of the bushings is displaced inwardly and the resilient structure is compressed. Thus, the resilient structure will oppose any displacement of the rod from its neutral position and the resilient structure will bias the rod towards its neutral position. Adjustment devices are provided for varying the forces exerted by the resilient structure.

Abstract: A shock absorber having controlled, continuous, adjustable resistance in both directions is obtained by means of a slide piston passing through a fixed collar and through two movable collars and elastic compression means abutting each movable collar.
