An optical sensor has a glass base having a concave portion, and a glass lid is bonded to the base and overlies the concave portion to form a cavity portion. A photoelectric conversion element id accommodated in the cavity portion. Internal wirings are each connected at one end to the photoelectric conversion element and extend through notches each formed at a corner of a peripheral edge along an outside surface of the base. The other ends of the internal wirings are connected inside the notches to external wirings that extend along an outside surface of the base and terminate in external terminals.

A developing device includes a developer bearer, a development casing in which a developer conveyance channel is formed facing the developer bearer through a communicating area, a developer supply member disposed in the developer conveyance channel, a developer regulator disposed facing a lower portion of the developer bearer to adjust an amount of developer carried on the developer bearer, and a sheet member that is removably installed to seal the communicating area and passes through a gap between the developer regulator and the developer bearer and an opening formed in the development casing. A first end of the sheet member is retained downstream from the gap in a direction of rotation of the developer bearer, and the sheet member is fixed to the development casing at a position across the communicating area from the first end with a second end positioned outside the development casing.

A conventional speech recognition dictionary, translation dictionary and speech synthesis dictionary used in speech translation have inconsistencies. Inconsistency among dictionaries can be solved with a dictionary server including an all-language group dictionary storage unit capable of having stored therein, for two or more languages, two or more all-language term information pieces for speech recognition, translation and speech synthesis, an information-for-speech-recognition sending unit that acquires information for speech recognition including speech recognition information of a term for all languages, and sends the information to one or more speech recognition servers, an information-for-translation sending unit that acquires information for translation including the written form of the term for all languages, and sends the information to one or more translation servers, and an information-for-speech-synthesis sending unit that acquires information for speech synthesis including speech synthesis information of a term for all languages, and sends the information to one or more speech synthesis servers.

摘要:
A powdered super absorbent polymer (SAP) has heretofore been used as a water retentive material for sanitary products, such as sanitary napkin, disposable diaper and incontinence pad. This water retentive material is used by being held between two paper sheets but the powdered SAP comes off easily from absorbent member. Moreover, even when the SAP is in a dried powdered state or in a water-absorbed gel state, it is moved between a top sheet and a back sheet in accordance with the movement of a wearer of the sanitary product. Consequently, water absorbency decreases with poor shape stability. Moreover, since the SAP in a water-absorbed gel state is sticky, the wearer feels unpleasant. According to the present invention, therefore, a cellulose fiber, such as a viscose rayon fiber containing uniformly a non-cellulose based material of high water absorbency such as polyacrylate salt is manufactured. A fiber web and nonwoven fabric produced of this fiber is used as water retentive materials in an absorbent member. This fiber has high absorbency and moreover high water retentivity such that water absorbed into the fiber is hardly released from the fiber. Accordingly, an absorbent member formed of a sheet made of this fiber has a stable shape both when it is in a dry state and when it is in a water-absorbed state, and, moreover, it has high absorbency and high water retentivity. Therefore, when this water-retentive sheet is used, a thin absorbent member of high absorbency can be provided.

A semiconductor device of the present invention has an LOC (Lead On Chip) structure. An end portion of an inner lead made thinner than an outer lead by cutting its lower surface by a predetermined thickness and a bus bar thinned to have the same thickness as the end portion of the inner lead are bonded to the surface of a semiconductor chip on which circuits are formed, with a protective film and an insulating tape interposed therebetween. A bonding wire is bonded to the thin portion of the inner lead or the thin bus bar. The thickness from the upper surface of the semiconductor chip to the upper surface of the inner lead can be reduced by the cut portion. A thin package can be realized without deteriorating the reliability with the normal thickness of the outer lead, the insulating tape and an encapsulating resin and the normal loop height of the bonding wire.
摘要:
A ring transmission system includes nodes connected in a ring shape by transmission lines to communicate with each other. Each node includes a cell extracting unit which receives a cell from the transmission lines and separates a control field from the cell in accordance with a communication control procedure, the control field including a number of bits containing management data and a destination, the management data indicating information related to maintenance and operation of the ring transmission system. A separating unit separates, from the control field, one of management data for the node and management data for another node by comparing the destination with an identification of the node. A management data processing unit generates processed management data from the management data when the destination indicates the node. An intermediate unit generates a new cell containing the management data from the separating unit when the destination indicates the another node. The management data of the new cell is distinctly different from the processed management data. The intermediate unit transmits the new cell to the transmission lines.
