This solid-state imaging device comprises a rib integrally formed with a bottom plate. A case for accommodating a solid-state imaging device, which can suppress warping from occurring at the time of molding the case and is less deformable by heat at the time of mounting is provided. The solid-state imaging apparatus is less likely to cause readout errors and the like even when the temperature for use varies, and is highly reliable in operation.

Case for accommodating solid-state imaging device and solid-state imaging apparatus

This method of manufacturing a lid made of a transparent resin comprises a step of introducing a resin into a cavity for molding a protrusion continuous with a cavity for molding a lid in a die; a step of forming a molded body including a lid and a protrusion continuous with the lid by solidifying the resin in the cavity for molding a lid and the cavity for molding a protrusion, respectively; a step of separating the molded body from the die by ejecting an ejector pin to the protrusion; and a step of separating the protrusion from the lid.

Lid made of resin for case for accommodating solid-state imaging device and solid-state imaging apparatus

A nonaqueous electrolytic solution cell having a negative electrode containing lithium as an active material, a positive electrode, a nonaqueous electrolytic solution consisting of solute and organic solvent, a separator, and an outer can, wherein the organic solvent contains a compound having an S&mdash;O bond, and a current collector for the positive electrode and an electrolytic solution-contacting portion on the positive electrode side of the outer can are made of valve metal or alloy thereof is disclosed. The nonaqueous electrolytic solution cell of the present invention is excellent in low-temperature characteristics and long-term stability, and also in cycle characteristics for use as a secondary battery.

Non-aqueous electrolyte cell with a solvent including a S-O bond

Disclosed is a non-aqueous electrolytic solution secondary cell having a negative electrode containing a carbonaceous material capable of occluding and liberating lithium, a positive electrode, a non-aqueous electrolytic solution which includes a solute and an organic solvent, and a separator; wherein the organic solvent contains at least one of compounds selected from those expressed by the formulae (I) and (II) below (in which &phgr; represents a phenyl group optionally having an alkyl group; and R represents any one of a hydrogen atom, C alkyl groups and a phenyl group optionally having an alkyl group). Such non-aqueous electrolytic solution secondary cell of the present invention is successful in suppressing decomposition of the electrolytic solution, and achieving a high capacity and excellent cycle characteristics.
