摘要:
A lens for reading an original has first to third lens groups sequentially arranged from an object side toward an image side. The first lens group is constructed by a first lens as a positive meniscus lens having a convex face on the object side. The second lens group is constructed by a second lens as a biconcave lens. The third lens group is constructed by a third lens as a biconvex lens. The first lens is constructed by a refractive index distribution type lens having a refractive index changed in a direction perpendicular to an optical axis of the original reading lens. Each of the second and third lenses is constructed by a refractive index distribution type lens having a refractive index changed in a direction of the optical axis. Otherwise, at least one of the first, second and third lenses may be constructed by a refractive index distribution type lens. In this lens construction, the original reading lens can be made compact and a field angle of this lens can be easily widened and high performance of the original reading lens can be easily realized.
摘要:
A zoom finder of a real image type has an objective lens having positive refracting power and an eyepiece having positive refracting power. The objective lens is constructed by first, second, third and fourth lens groups sequentially arranged from an object side. The first lens group has positive refracting power. The second lens group has negative refracting power. The third lens group has positive refracting power. The fourth lens group has positive refracting power. The zoom finder is constructed such that a real image is focused and formed by the objective lens between the fourth lens group and the eyepiece and is observed through the eyepiece. A magnification of the zoom finder is increased by moving the second lens group from the object side to an eyepiece side. A change in diopter caused by this increase in magnification is corrected by moving the fourth lens group. In accordance with the above structure, an entire length of the zoom finder is short and is not changed in a zooming operation. Further, the structure of a mechanical mechanism for displacing lenses in the zooming operation is simplified and no diopter of the zoom finder is changed in the zooming operation.

摘要:
An object of the present invention is to provide a water-solubilizing preparation that is obtained by convenient steps without use of a special apparatus such as a high-pressure homogenizer, does not impair the original properties of a water-based material even after being added to the material, has high dispersibility and transparency and excellent heat resistance and acid resistance, and can maintain stability. The water-solubilizing preparation of the present invention is a biologically active substance-containing water-solubilizing preparation comprising 1 to 50% by weight of an oily ingredient (A) containing a biologically active substance and oil, 10 to 98% by weight of a polyglycerin fatty acid ester (B) having an HLB value of 12.5 or larger, and 1 to 40% by weight of a surfactant (C) having an HLB value of 7 to 11.8.
摘要:
A network monitoring device which monitors a network in which data is transmitted through relays, includes a monitoring frequency recording unit (111) which records monitoring frequencies for monitoring transmission statuses of the relays, a selection probability generating unit (112) which generates selection probability information which is probability values for the relays, a monitoring object determining unit (113) which determines, according to the monitoring frequency and the selection probability information, a relay the transmission status of which is to be monitored, a transmission status obtaining unit (106) which obtains transmission status information indicating a transmission status on the relay determined, a transmission status recording unit (107) which records the transmission status information, an activation level calculating unit (109) which calculates, using the transmission status information, activation level indicating suitability of the monitoring on the transmission statuses of the relays, and a monitoring frequency updating unit (110) which updates, based on the activation level, the monitoring frequency, and the network monitoring device detects the change in throughput on a data transmission path highly responsively.
