摘要:
A data processor (1) has a central processing unit (3) and a memory controller (6) capable of controlling a memory (8) to be connected to an outside. The memory has a buffer capable of temporarily holding data within an address range corresponding to a predetermined bit number on a low order side of an address signal, and a burst operation for inputting/outputting data can be carried out by a data transfer between the buffer and the outside for an access request in which an access address is changed within the address range. When causing the memory to carry out the burst operation to give an access, the memory controller performs an access control for freely executing the burst operation of the memory continuously if it detects an access exceeding the address range. When causing the memory to carry out the burst access, the memory controller performs an access control for freely executing the burst operation of the memory continuously if it detects the access exceeding the address range. Therefore, it is not necessary to restrict the burst access exceeding the address range and to limit a burst frequency. Consequently, it is possible to enhance a data transfer performance through the burst access together with the memory.

The present inventors discovered that the onset of galactosamine hepatopathy is suppressed by nutritional compositions comprising as essential ingredients: whey protein hydrolysates; lecithin and oils and fats high in oleic acid, which are able to improve the lipid metabolism; and palatinose having an insulin-sparing effect. Furthermore, the whey protein hydrolysate included in the nutritional compositions was found to suppress endotoxin-induced TNF-a and interleukin 6 (IL-6) production in macrophages.

A method for producing a thin film solar cell includes preparing a substrate of a low purity material and having opposed front and rear surfaces; forming an insulating film on the front surface of the substrate; forming a second conductivity type active layer of a high purity material on the insulating film with a front surface exposed; forming a second conductivity type semiconductor region within the active layer, reaching the front surface, to produce a p-n junction for light-to-electricity conversion; forming an anti-reflection film on the front surface of the active layer, the anti-reflection film reducing reflection of incident light; forming a surface electrode in contact with the front surface of the active layer; adhering the front surface side of the active layer to a supporting plate and selectively etching the low purity substrate from the rear surface to form a supporting substrate supporting the active layer; and forming a rear electrode on the rear surface of the supporting substrate contacting the active layer.
摘要:
A method for producing a thin-film solar cell having a thin-film active layer on a graphite sheet substrate includes the steps of adhering two sheets of graphite together, forming semiconductor thin films serving as active layers on second main surfaces of the two sheets of graphite, and separating the two sheets of graphite from each other. In this structure, stress caused by a difference in expansion coefficients between the upper sheet and the semiconductor thin film is cancelled by stress caused by a difference in expansion coefficients between the lower sheet and the semiconductor thin film. Therefore, curvature of the substrates is prevented whereby subsequent process steps are easily carried out. In addition, the number of products per unit time is doubled, thereby increasing productivity.
