摘要:
A process for producing triterpene alcohol, comprising sequentially conducting the following steps (A) to (C): (A) subjecting γ-oryzanol to alkaline hydrolysis; (B) mixing the alkaline hydrolysate with a low polarity organic solvent, and extracting triterpene alcohol to obtain a triterpene alcohol-containing low polarity organic solvent; and (C) adding water to the triterpene alcohol-containing low polarity organic solvent thus obtained, removing the low polarity organic solvent, and then melting triterpene alcohol in hot water, followed by cooling.

In order to provide a phosphor for a low-voltage electron beam and a vacuum fluorescent display apparatus in which the phosphor is used, a deposition layer is formed on a surface of a main body of a phosphor shown by the following chemical formula (1), the deposition layer being a plurality of oxide layers sequentially deposited on the surface of the phosphor main body. The phosphor for a low-voltage electron beam contains no cadmium, but has exceptional high-temperature exposure characteristics, as well as prolonged service life and higher brightness. Ca1-xSrxTiO3:Pr,M (1) where M is at least one element selected from Al, Ga, In, Mg, Zn, Li, Na, K, Gd, Y, La, Cs, and Rb; and 0≦x≦1.

摘要:
The method is adapted for forming an aluminum nitride thin film having a high density and a high resistance to thermal shock by a chemical vapor deposition process and includes steps of mixing a gas containing aluminum atoms (Al) and a gas containing nitrogen atoms (N) with a gas containing oxygen atoms (O) and feeding the mixture to a member to be covered by an aluminum nitride thin film.
摘要:
A compound has an intestinal phosphate transporter (NPT-IIb) inhibitory action and is useful as an active ingredient of an agent for treating hyperphosphatemia, preventing hyperphosphatemia, or both. The compound is a tetrahydrobenzothiophene compound. A pharmaceutical composition for treating hyperphosphatemia includes the compound or salt thereof. A method of treating hyperphosphatemia includes administering to a subject an effective amount of the compound or salt thereof.
摘要:
A process cartridge includes a photosensitive drum, a charging unit, a developing unit, and a cleaning unit, arranged opposite to each other along a rotating direction of the photosensitive drum in an enclosure that has an opening opposite to a developing roller of the developing unit. An extended line connecting a tangent line to an outer circumference of the developing roller and a wall of a first end of the enclosure in an axial direction of the developing roller does not intersect with a wall of a second end of the enclosure.
摘要:
A toner cartridge is configured by integrally arranging a fresh toner storing chamber and a residual toner collection chamber. Fresh toner is filled in the fresh toner storing chamber through a fresh toner filling opening. Residual toner is conveyed in the residual toner collection chamber through a residual toner conveying opening. Two residual toner discharging openings are created in the residual toner collection chamber through which the residual toner is discharged.

A toner conveyer device for use din an image forming apparatus includes a toner conveyer belt conveys waste toner, a screw member that receives the waste toner from the toner conveyer belt and conveys the waste toner to a housing unit, and a scraping member that scrapes waste toner that adheres to the screw member.
摘要:
A high-ratio zoom lens system includes a positive first lens group, a negative second lens group, a positive third lens group, and a positive fourth lens group. Upon zooming from the short to long focal length extremities, the lens groups move while increasing the distance between the first and second lens groups, and decreasing the distance between the second and third lens groups. The first lens group includes a negative lens element having a concave surface on the image side, a positive lens element having a convex surface on the object side, and a positive lens element having a convex surface on the object side, in that order from the object side. The following conditions (1) and (2) are satisfied: 1.7
摘要:
A system and process for capturing and rendering ink is described. An ink canvas object may contain none, one, or more objects or elements and may specify the z-order of the objects or elements. The ink canvas object may host a variety of objects or elements and, therefore, provide ink functionality to the objects or elements, even though the objects or elements themselves may not have ink functionality. The ink canvas object is attached to an ink editor that has an associated modifiable ink editor behavior, whereby ink specific behaviors are collected in the ink edit behavior.
摘要:
A camera according to the present invention includes a picture-taking lens unit including a picture-taking optical system having a bending optical system which optically bends incident light and an optical finder unit including a finder optical system having a bending optical system which optically bends incident light. A pre-bending optical system and a post-bending optical system in the bending optical system of the optical finder unit are arranged adjacent to a pre-bending optical system and a post-bending optical system in the bending optical system of the picture-taking lens unit, respectively. The body of the camera is therefore decreased in size.
