摘要:
The present invention provides a lithium secondary battery using a separator including a porous film formed by binding inorganic oxide particles together with a binder. The inorganic oxide particles are treated so that an amount of alkali metal elements eluted therefrom when they are immersed in ion exchange water is reduced to 1000 ppm or less. As a result, it is possible to provide a lithium secondary battery with a high degree of reliability, whose characteristics deteriorate less when it is used or stored for an extended period.

The separator for an electrochemical device of the present invention includes inorganic fine particles and a fibrous material or microporous film. Primary particles of the inorganic fine particles can be approximated to a geometric shape, and a difference between a theoretical specific surface area and an actual specific surface area of the inorganic fine particles is within ±15% relative to the theoretical specific surface area, where the theoretical specific surface area of the inorganic fine particles is calculated from a surface area, a volume and a true density of the primary particles of the inorganic fine particles, which are determined through approximation of the primary particles of the inorganic fine particles to the geometric shape, and the actual specific surface area of the inorganic fine particles is measured by the BET method.

Front and rear side flange portions of a filter accommodating cylinder are provided with positioning pins. A flange portion of an upstream cylinder is provided with a notched groove and a flange portion of a downstream cylinder is provided with a notched groove. In consequence, when the filter accommodating cylinder is connected between the upstream cylinder and the downstream cylinder, each of the positioning pins disposed at the front and rear flange portions is engaged with each notched groove of the upstream cylinder and the downstream cylinder. The filter accommodating cylinder can be positioned to be coaxial with the upstream cylinder and the downstream cylinder. As a result, after performing a cleaning operation to a DPF, an operation of once again connecting the filter accommodating cylinder between the upstream cylinder and the downstream cylinder can be quickly and easily performed.

An engaging groove (47) with which a gasket (42) is engaged is provided in each of a front side projecting portion (44) and a rear side projecting portion (46) formed in a filter accommodating cylinder (37) to be positioned on an outer peripheral surface (44A, 46A) of each projecting portion (44, 46). Therefore, when the gasket (42) latches on each of the projecting portion (44; 46) to be fitted thereon from an outside, the gasket (42) can be engaged with the engaging groove (47) provided in each of the projecting portions (44, 46). In consequence, at the time of mounting and removing the filter accommodating cylinder (37), the falling-off of the gasket (42) can be prevented, and, for example, an inspection operation, a cleaning operation and the like of an accommodated particulate matter removing filter (41) can be easily performed.

In a microcomputer equipped with a built-in temperature sensor, diodes as a temperature sensor are incorporated in a pair of circuit blocks, respectively, and placed in opposite polarity connection to each other. When detecting a temperature of the microcomputer, a constant current If is supplied to the diodes through terminals commonly connected to both the diodes. A voltage Vf generated at each diode is read through terminals located at more adjacent nodes to the diode when compared in position with the terminals.

An image-recording transparent film comprising a flexible film transparent to visible light and a recording layer on which an image is formable with an image-forming apparatus and which is provided on a surface of said flexible film, in which at least a part of the film has an absorption peak in a wavelength range between 250 nm and 400 nm, an absorption peak in a wavelength range between 700 nm and 1200 nm, and an IR light transmission of 40% or less.
摘要:
An improved method of forming a photoresist pattern in the photoengraving process. In the photoengraving process, after forming a photoresist layer, a non-photosensitive organic layer containing cyclized polyisoprene rubber as the major constituent is formed thereover. The organic layer is covered with a mask. The photoresist layer is selectively exposed to light through the organic layer. After developing and removing the organic layer, or together with the organic layer, the photoresist layer is developed.
