摘要:
A process for producing a resin substrate having a hard coating layer on at least one side of a resin substrate, comprising, in the following order, a step of applying a hard coating composition containing an organopolysiloxane to at least one side of the resin substrate to form a coating film of the composition, and then applying a first heat treatment to the coating film to form a cured film; an irradiation step of applying a Xe2 excimer light irradiation treatment to the cured film in an atmosphere having an oxygen concentration of at most 5 vol %; and a step of applying an oxidation treatment to the cured film obtained by the irradiation step and then further applying a second heat treatment to form the hard coating layer.

A process for enabling the production of a particulate composition containing crystalline trehalose dihydrate is provided. Including allowing an α-glycosyltrehalose-forming enzyme to act on liquefied starch derived from a microorganism of the genus Arthrobacter and a trehalose-releasing enzyme derived from a microorganism of the genus Arthrobacter along with a starch debranching enzyme and a cyclomaltodextrin glucanotransferase; allowing glucoamylase to act on the resulting mixture to obtain a saccharide solution containing α,α-trehalose; precipitating crystalline α,α-trehalose dihydrate from the above saccharide solution; collecting the precipitated crystalline α,α-trehalose dihydrate by a centrifuge; and ageing and drying the collected crystals. Cyclomaltodextrin glucanotransferase derived from a microorganism of the genus Paenibacillus or a mutant enzyme thereof is used to increase the α,α-trehalose content in the saccharide solution to over 86.0% by weight, on a dry solid basis, without passing through a fractionation step by column chromatography.

The image forming apparatus includes a conductive member provided in a conveying path of a recording material, a voltage applying device for applying a voltage to the conductive member, a current detecting device for detecting a current flowing in the conductive member when the recording material passes through the conductive member to which a voltage is applied by the voltage applying device, and a judgment device for judging, based on an output from the current detecting device, whether a conductive foreign object is present on the recording material. Thus there is provided an image forming apparatus capable of detecting a foreign object attached to a recording material by a simple method.
摘要:
The object of the present invention is to provide a powdery product comprising crystalline β-maltose monohydrate which is powderized by spray method, and has a high-solubility in aqueous solvents and a satisfactory handleability, and to its preparation and uses. The present invention solves the above object by establishing a powdery product comprising crystalline β-maltose monohydrate which comprises 7% (w/w) or more but less than 14% (w/w) (x-anomeric maltose, and has a crystallinity of 62% or more but less than 72%; a process for producing thereof which comprises the steps of producing a massecuite from an aqueous maltose solution comprising 86% (w/w) or more but less than 93% (w/w) of maltose and 2% (w/w) or more of glucose, on a dry solid basis, powderizing by a spray method, keeping in a relatively low humidity and a relatively high temperature, and further keeping in a relatively high humidity- and a relatively low temperature-condition; and uses thereof for various compositions such as foods, cosmetics, and pharmaceuticals.

A propolis extract having a reduced peculiar odor is prepared by deceasing the amount of odorizing ingredients. This propolis extract can be used to prepare biologically active compositions.
摘要:
Disclosed are a novel desiccant containing a non-reducing anhydrous trehalose as an effective ingredient; a dehydration of hydrous matters, e.g. food products, pharmaceuticals and cosmetics, therewith; and dehydrated products obtained by the dehydration. Such hydrous matters are dehydrated without causing alteration or deterioration by incorporating anhydrous trehalose into the hydrous matters to convert the anhydrous trehalose into hydrous crystalline trehalose. The anhydrous trehalose are anhydrous crystalline trehalose and hydrous amorphous trehalose.
