摘要:
With branched epoxy(meth)acrylate which comprises a phenyl skeleton serving as a stiff molecular skeleton, and which comprises in the molecular skeleton a number of branched structures capable of forming a coating structure at a high crosslinking density after ultraviolet curing, it becomes possible to design the coating hardness to be high even if the content of an acryloyl group is designed to be low to effect less crosslinking reaction induced by ultraviolet curing, and it becomes possible to relax distortions inside a cured film due to cure shrinkage which occurs at the time of ultraviolet curing. As a result, there can be realized an ultraviolet-curable composition for an optical disk which has a high elastic modulus and is less tilted at the time of curing even if the coating hardness is designed to be high.

An object of the present invention is to provide a system that ensures safety when an airframe makes a sudden and sharp vertical movement, the system operating automatically to restrain movement of a service cart in a vertical direction such that the workload of a cabin attendant is not increased and there is no need for structural design modifications of the airframe. The safety device for a service cart of the present invention is designed to prevent the cart from floating upward by engaging a part of the cart with a fitting on the passenger seat, and comprises a sensor constituted by a combination of an inertial member and a spring to detect a sudden vertical motion of the airframe and a mechanism which causes plates to protrude from both the left and right sides of the cart using a detection signal of the sensor as a trigger. The protruding plates are then engaged.

A hydro-pneumatic suspension system adapted to be connected to first and second sides of a vehicle for leveling the vehicle in a side-to-side direction includes first and second absorbers, a pump and a gas spring element. Each of the first and second absorbers includes a piston rod provided with a piston for slidingly engaging a cylinder and an actuating chamber for an actuating liquid formed between the cylinder and the piston. The pump and the gas spring elements are connected to the actuating chamber of the first and second absorbers to control the flow of the actuating liquid. The pump and the gas spring element are independent from the first and second absorbers.

The present invention provides a method for producing an aqueous dispersion of thermoplastic resin microparticles containing considerably less residual solvent remaining in resin particles, and a toner for electrophotography containing considerably less residual solvent. A self-water-dispersible thermoplastic resin is swollen using an organic solvent having a boiling point lower than 100° C., which does not dissolve but can swell the self-water-dispersible thermoplastic resin, to produce a swollen material and the resulting swollen material is dispersed into an aqueous medium in the form of microparticles to produce an initial aqueous dispersion, and then the organic solvent is removed from the initial aqueous dispersion to prepare a dispersion. A toner for electrophotography contains microparticles obtained by separating microparticles of the self-water-dispersible thermoplastic resin from the aqueous dispersion of thermoplastic resin microparticles and drying the microparticles.

A mobile robot placed on an automatic production line is provided. The mobile robot collects information on operating conditions of other mobile robots placed around it and flow of workpieces on the production line and determines action to be taken next based on the formation. A production system using such a mobile robot and a system inputting an operation program corresponding to a workstation into a mobile robot automatically are also provided. This enables measures to be taken quickly against a change in production, thereby providing a system which achieves high efficiency production.
摘要:
A brake cylinder device with a built-in automatic shoe clearance adjustment device which prevents a chance of misassembly, loosing, or omitting the spacer. The brake cylinder device includes an adjustment bolt screwed into a pair of pistons symmetrically slidably positioned inside a cylinder body. A locator spring is positioned between both adjustment bolts. A locator is positioned at the end of the locator spring, and a spacer engages the top end of the locator and has a supporting portion to support the top end on the axis of the adjustment bolt. The supporting portion of the spacer has the front and back surfaces of the same shape.
