In order to solve a conventional problem that it is not possible to manage partial content in a webpage as a block and execute processing on the block, a webpage processing apparatus includes: a block information storage unit in which one or more pieces of block information each having a block identifier for identifying a block, which is partial content in a webpage, and location identifying information for specifying a location of the block in the webpage are stored; a block processing unit that executes block processing, which is processing regarding a block specified with block information, using location identifying information contained in any one of the one or more pieces of block information; and a result output unit that outputs a block processing result, which is a result of the block processing. Accordingly, it is possible to manage a block, which is partial content in a webpage, and execute processing on the block.

Web page processing apparatus and method using block information within web

[Solution] Provided is a water purification agent suitable for use in an automated purification treatment device, when a wastewater purification treatment using a plant-derived water purification agent is performed with the automated purification treatment device. The water purification agent is a granulated product containing a mixture of a plant powder and a polymer coagulant.

Water purification agent and water purification method

Provided is a water-purifying agent that is excellent in water purifying performance, can be suitably used in an automated wastewater purification apparatus, and is formed of a granulated product including a mixture of a powder ofand a polymeric flocculant, wherein a median diameter of the granulated product is 250 micrometers or greater but 850 micrometers or less.

Water cleaning agent and water cleaning method

[Solution] Provided is a plant-derived water purifying agent used for water purification for industrial wastewater, etc. and including a granulated product of a plant powder, such that when a wastewater purifying treatment using the plant-derived water purifying agent is performed by an automated purifying treatment device, the water purifying agent can be suitably used in the automated purifying treatment device. It is more preferable that a Carr's fluidity index of the water purifying agent obtained by measuring 3 items of the water purifying agent, which are an angle of repose, a degree of compression, and a spatula angle be 40 or greater.

Water-purifying agent and water purification method

A thermoplastic resin finely-foamed reflective sheet, containing: a foamed layer; and non-foamed layers, each of which has a thickness of 150 &#x3bc;m or less and 30 &#x3bc;m or more, and which are provided one above the other while sandwiching the foamed layer between the non-foamed layers, wherein the thermoplastic resin finely-foamed reflective sheet has an integrated structure, wherein the foamed layer is a thermoplastic resin finely-foamed product having a homogeneous bubble structure, in which an average bubble diameter is 10 &#x3bc;m or less and 0.5 &#x3bc;m or more, and in which a bubble number density is 1&#xd7;10/mmor more and 1.0&#xd7;10/mmor less, and wherein at least one of the non-foamed layers comprises a functionality-providing layer.

Thermoplastic resin finely-foamed reflective sheet, light-reflecting plate, backlight panel, and method of producing the foamed reflective sheet

A control method applicable to an electrophotographic copier for protecting the background of copies against smears due to a residual potential on a photoconductive element. Before a visible pattern is produced, the photoconductive element is charged by a lower potential than a charging potential which is adapted to form a document image and, then, it is discharged. Potential remaining on the photoconductive element which has been discharged is developed to produce the visible pattern, and the density of this pattern is optically detected. Based on the density level of the visible pattern detected, at least one of a developing bias potential, a charging potential and an exposing potential which are to form a document image is corrected. In the event of producing the visible pattern, the potential remaining on the photoconductive element is developed by a developing bias potential which has been corrected on the bias of visible pattern density level detected immediately before. In a multi-color electrophotographic copier which uses a plurality of colors of toner, the visible pattern is produced by using one particular color of toner which is advantageously black toner.

Method of controlling surface potential of photoconductive element

An electrophotographic copying process and apparatus fast in operation and capable of making reproduced images having substantially the same image density is provided. In accordance with the present invention, pre-exposure is carried out only when a photosensitive member is to be used for image formation after elapsing a predetermined time period during which the photosensitive member has been kept unused. The present invention is fast in operation and minimal in power consumption because the pre-exposure is skipped when unnecessary. However, since pre-exposure is effected when necessary, the image density may be maintained at constant.
