摘要:
A silver halide photographic light-sensitive material is disclosed, which is excellent in light discoloration resistance and is more particularly capable of keeping its color balance and reproducing long life color images. The photographic material comprises a support, at least three light-sensitive silver halide emulsion layers containing a yellow, magenta, and cyan coupler, respectively, and at least one non-light-sensitive layer being provided at a further side of the emulsion layer being provided at the furthest position from the support. The non-light-sensitive layer contains at least three kinds of UV absorbers represented by the general formula [UV-I], provided that at least one of the UV absorbers is in a liquid state at 30.degree. C. and at least two UV absorbers are in a solid state at the same temperature. ##STR1## And the emulsion layer containing the yellow coupler contains a compound represented by the general formula [A]: ##STR2##
摘要:
To simplify both the printed circuit board connector structure itself and the circuit board connecting work, the improved circuit board connector comprises a connector body and plural roughly U-shaped spring contacts elastically housed within the connector body. Circuit boards to be connected are engageable with the board connector in card edge connection manner or in bolt-nut connection manner. The above board connector is simple in structure and in connecting operation so as to be available for an automatic mass-production assembly process line.
摘要:
In an electrical connector locked and released by means of snap members, a supporting axle of the snap member is located between a sector-shaped bottom surface of the snap member and center of curvature of the sector so as to allow pivotal axis of the snap member to travel along elongated holes provided in the side walls as the snap member is pivoted and/or knurled edge and rib are provided at the top end of the snap member for guiding the female connector toward the male connector pins so as to align the pin holes of the female connector with the male connector pins.

A method for the preparation of semipermeable membrane which comprises exposing porous shaped articles of polysulfone to a plasma.The resulting semipermeable membrane is very useful for separating substances by reverse osmosis or ultrafiltration.
摘要:
Ultrathin membranes for separating substances are obtained by exposing shaped articles comprising a water-soluble polymer or a mixture of a water-soluble polymer and water-insoluble polymer to a plasma of a gas selected from helium, argon, nitrogen, hydrogen, oxygen, carbon monoxide, carbon dioxide, ammonia, a hydrocarbon having 1 to 10 carbon atoms, an epoxide having 2 to 10 carbon atoms, or an alkylamine, or a mixture of these substances to crosslink the surface layer, and then washing the exposed articles with water to remove the unreacted portions. The membrane exhibits outstanding performance characteristics when used in the processes for separating or concentrating substances, such as reverse osmosis, ultrafiltration, and the like.

An information processing apparatus includes a data storage portion that stores data records in which second data is associated with first data; a communicating portion that communicates with an external device; an updating portion that receives the data records from the external device and updates the data records; a screen controlling portion that displays one or more of the first data or the second data, and that receives a specifying operation specifying the first data; a determining portion that determines whether the information processing apparatus is in a state, in which control that uses the first data will be started in response to the screen controlling portion receiving the specifying operation; and a caching portion that caches the first data specified by the specifying operation separately from the data records stored in the data storage portion, when it is determined that the information processing apparatus is in the state.
摘要:
Heat generated by a drive source of a friction drive device such as an electric motor is allowed to efficiently dissipate to the atmosphere, and the friction drive device and an omni-directional vehicle using the same is designed in a highly compact manner. Left and right electric drive devices are placed on a central axial line of left and right rotatable drive members, and external teeth members serving as output members of the electric drive devices are directly connected to the respective rotatable drive members in a torque transmitting and heat transmitting relationship.
