A pretreatment method for saccharification of plant fiber materials includes: immersing the plant fiber material in a solution that contains an organic solvent, in which a cluster acid is dissolved, prior to saccharifying cellulose contained in the plant fiber material; and distilling off the organic solvent from the immersed plant fiber material to obtain a pretreated mixture that contains the cluster acid and the pretreated plant fiber material.

The invention relates to a method for hydrolyzing a plant fiber material and producing and separating a saccharide including glucose. The method of the invention includes a hydrolysis process of using a cluster acid catalyst in a pseudo-molten state to hydrolyze cellulose contained in the plant fiber material and produce glucose. In the hydrolysis process, the cluster acid catalyst and a first amount of the plant fiber material that increases a viscosity of the cluster acid catalyst in a pseudo-molten state when added to the cluster acid catalyst in a pseudo-molten state are heated and mixed, and a second amount of the plant fiber material is then further added when the decrease in viscosity of the heated mixture occurs.

A nonvolatile semiconductor memory device includes: a semiconductor substrate; a first gate electrode formed on the semiconductor substrate through a gate insulating film; a second gate electrode formed in a side direction of the first gate electrode and electrically insulated from the first gate electrode; and an insulating film formed at least between the semiconductor substrate and the second gate electrode to trap electric charge, as an electric charge trapping film. The first gate electrode comprises a lower portion contacting the gate insulating film and an upper portion above the lower portion of the first gate electrode, and a distance between the upper portion of the first gate electrode and the second gate electrode is longer than a distance between the lower portion of the first gate electrode and the second gate electrode.

The medical catheter tube of the present invention integrally has an inner layer tube; reinforcement material layers formed by placing element wires on the inner layer tube; a marker; and an outer layer tube. The element wires, which are first and the other element wires, for forming the reinforcement material layers are synthetic resin element wires and/or metallic element wires, the first element wires are placed in the axis direction of the catheter to form the first reinforcement material layer, and the other element wires are wound in a coil form on the first reinforcement material layer, in the circumferential direction of the catheter, to cover the first reinforcement material layer. The marker is flexible to deformation. Because of the presence of the reinforcement material layer and the outer layer tube, flexural rigidity from a base section to a head section is reduced in a stepped or continuous manner.

An optical deflector, a method of producing the optical deflector, an optical scanning device, and an image forming apparatus are disclosed that are able to save resources, provide high reliability at low cost, and enable stacked and relatively-offset polygon mirrors to be arranged precisely. The optical deflector includes a rotary member supported by a bearing with plural polygon mirrors fixed thereon. The polygon mirrors are stacked along a rotation axis of the rotary member, the polygon mirrors are relatively offset by a predetermined angle in a rotation plane of the rotary member, and an effective deflection area of each of the reflection surfaces of any one of the polygon mirrors is positioned away from a center of the corresponding reflection surfaces of the other one of the polygon mirrors in the direction of the rotation axis.

A user accesses a sound data distribution server by operating a client terminal. The sound data distribution server transmits data for displaying a list of distributable music. The data are displayed on a display unit of the client terminal. While referring to the display on the display unit, the user requests the sound data distribution server for distribution of regular music data. This request is issued from the client terminal. A cellular phone to which the regular music data are to be distributed is specified by data (e.g., a mail address of the cellular phone) input at the client terminal. This enables the sound data distribution server to recognize the cellular phone and distribute the regular music data to the cellular phone.
摘要:
A method of forming a nonvolatile memory device which includes forming a first gate electrode on a gate insulating film formed on a semiconductor substrate. The first gate electrode having a lower portion formed on the gate insulating film and an upper portion having a gate length less than that of the lower portion formed on the lower portion. A spacer is formed contacting surfaces of the upper and lower portions, wherein a length of the spacer and the upper portion equals the length of the lower portion. An electric charge trapping film covers a portion of the semiconductor substrate, a surface of the lower portion, and a surface of the spacer. A second gate electrode is then formed in a side direction of the first gate electrode and electrically insulated from the first gate electrode by the electric charge trapping film. The second gate electrode has a distance between the upper portion of the first gate electrode thai is greater than a distance between the lower portion and is separated from the upper portion of the first gate electrode by the electric charge trapping film and the spacer.
