摘要:
A method of preparing aqueous solutions of sterol glycosides and their ester derivatives characterized by solubilizing sterol glycosides and their ester derivatives by (1) dissolving said sterol glycoside or ester in a lower aliphatic alcohol and subsequently adding a hydrophilic non-ionic surface active agent, or (2) mixing or dissolving said sterol glycoside or ester with or in a lipophilic surface active agent or its solution in an organic solvent miscible with water and subsequently adding a hydrophilic surface active agent.

A powder conveying device includes a drop conveyance passage, an intersecting conveyance passage, a conveying screw, and a floating member. Powder entering from an inflow port drops in the drop conveyance passage. The intersecting conveyance passage communicates with a lower end of the drop conveyance passage and extends in an intersecting direction that intersects the drop conveyance passage. The conveying screw is disposed in the intersecting conveyance passage and rotates in a specified direction to convey the powder in the intersecting direction. The floating member is movably installed in the drop conveyance passage and floats in the drop conveyance passage to move by contact with the conveying screw. The inflow port and the floating member interfere with each other to prevent the floating member from coming out of the inflow port of the drop conveyance passage.

An inkjet ink including: a stilbene-based compound represented by General Formula (1) below; where in the General Formula (1), R1 and R3 each independently represent, for example, an alkyl group including 1 to 20 carbon atoms, an alkenyl group including 1 to 20 carbon atoms, a phenyl group, or a naphthyl group.
摘要:
A powder container is insertable in an image forming apparatus. The powder container includes a plurality of transmitted surfaces, at least one of the transmitted surfaces being configured to contact a first protrusion of the linage forming apparatus, the first protrusion being rotatable and protruding toward an upstream side in an insertion direction in which the powder container is inserted. The transmitted surfaces stand outward from an outer circumference of the powder container so that one of the transmitted surfaces is connected to another transmitted surface adjacent to the one of the transmitted surfaces by an inclined surface.

A developing device includes a developer bearer to carry, by rotation, developer including toner and magnetic carrier to a developing range facing a latent image bearer; a casing including a developer container and an opening to expose a part of the developer bearer disposed in the casing; an opposing face of the casing including a conductive material and opposing to a surface of the developer bearer downstream from the developing range in a direction of rotation of the developer bearer; a developing bias source to apply a developing bias to the developer bearer; and an insulation layer disposed on the opposing face of the casing. The opposing face is disposed across, from the developer bearer, a casing gap sized to allow the developer borne on the developer bearer to contact the opposing face.

A solar light collecting mirror includes a reflective section which is elastically deformable, and a frame which is elastically deformable and configured to support the reflective section. A central portion of the reflective section is positionally fixed in X and Y directions of the reflective section. A relative position in a Z direction between the central portion of the reflective section and a peripheral portion of the reflective section is changeable. The peripheral portion of the reflective section is not positionally fixed in the X and Y directions. The frame includes warp members which radially extend from a position corresponding to the central portion of the reflective section. And the reflective section is configured to deform elastically together with the frame so as to change the relative position in the Z direction between the central portion and the peripheral portion, whereby a concave mirror structure is obtained.

A voltage-controlled oscillating circuit includes a differential amplifying circuit connected to a resonant element such as a quartz crystal element. The differential amplifying circuit includes first and second input terminals connected to the resonant element and also connected respectively to first and second voltage-controlled capacitors. The differential output terminals of the differential amplifying circuit are connected respectively to first and second emitter follower circuits. The output signal of the first emitter follower circuit is fed back to the second input terminal through a third capacitor and a third voltage-controlled capacitor, and the output signal of the second emitter follower circuit is fed back to the second input terminal through a fourth capacitor and a fourth voltage-controlled capacitor. A control voltage is applied to each of the voltage-controlled capacitors.
