Each cell grouping (1251, 1751) includes a plurality of cell packs (52, 1752) electrically coupled in parallel including a negative terminal (70, 270) and a positive terminal (64, 264). Each plurality of framed heatsink assemblies (50, 250) is disposed between one cell pack (52, 1752) of the plurality of cell packs of each cell groupings (1251, 1751) and an adjacent cell pack (52, 1752) of the plurality of cell packs of each cell grouping (1251, 1751) and includes a thermally conductive sheet portion. Each of the plurality of jumper tabs (32, 232) electrically couples a negative terminal (70, 270) of one of the plurality of cell groupings (1251, 1851) to a positive terminal (64, 264) of an adjacent cell grouping (1251, 1851).

To prevent the peeling-off of a drive circuit chip from an insulation substrate of a display device attributed to a residual stress between terminals formed on the insulation substrate and bumps formed on a mounting surface of a drive circuit chip, as well as to stabilize the connection resistance therebetween, the present invention provides an auxiliary bump for one of the bumps on the mounting surface of the drive circuit chip at an end edge side thereof with respect to the one of the bumps and arranges the auxiliary bump electrically in contact with one of the terminals formed on the insulation substrate of the display device with which the one of the bumps also is in electrical contact. Since the one of the bumps is spaced from the end edge side of the mounting surface of the drive circuit chip by the auxiliary bump, electrical contact thereof with the one of the terminals cannot be affected by the atmospheres in which the display device is used, and distortion of a signal waveform caused thereat can be suppressed also.

Disclosed are a separator for lithium ion secondary batteries, having an inorganic layer formed from inorganic particles, characterized in that the inorganic particles have a particle diameter distribution in which the 50% cumulative particle diameter D₅₀ is in the range of 100 nm to 500 nm, the 10% cumulative particle diameter D₁₀ is 0.5D₅₀ or more, and the 90% cumulative particle diameter D₉₀ is 2D₅₀ or less; a method for manufacturing the separator; and a lithium ion secondary battery using the separator. When the separator is used, there can be produced a lithium ion secondary battery in which a short circuit caused by contraction or melting can be definitely prevented, as well as the current density applied to the electrodes during charging and discharging is uniform so that charging and discharging can be efficiently achieved.

An indwelling urinary catheter having a simple structure that can discharge urine easily is disclosed. The indwelling urinary catheter comprises a body that includes an inserted part to be inserted into the bladder, and a non-inserted part that is formed in one body with the inserted part and positioned outside of the bladder, a discharging tube installed inside of the body for discharging the urine, the first fixing member formed inside of the inserted part, and an expander one end of which is fixed to the first fixing member. Typical problems associated with the conventional balloon-shaped fixing member are resolved because the indwelling urinary catheter is fixed in a desirable position by an expanding a part of the body. Also, because the indwelling urinary catheter of the present invention needs no additional fixing devices such as the balloon-shaped fixing device but instead can be fixed by the expander, it has a simple structure and enlarged inner diameter of the discharging tube. Thus urine is discharged from the bladder effectively. Moreover, the indwelling urinary catheter has a long life and can be manufactured economically and quickly due to the simple and effective structure.

An improved wave energy converter for use in offshore and deep-sea locations. The wave energy converter is adapted for secure attachment to the bottom of a body of water (e.g., the ocean floor), preferably beyond the breaker zone. The wave energy converter is selectively adjustable in length. A hydraulic power generation system is used to convert the energy present in the waves into hydraulic power that can be use to generate electricity and for other purposes, such as desalinization. The system may include a hydraulic piston assembly, a floatation device that is connected to the piston assembly, high and low pressure hydraulic reservoirs, and a hydraulically driven power generator. The floatation device moves upward in response to rising waves, and downward under the force of gravity in response to falling waves. The system utilizes this downward gravitational force to discharge fluid from the piston assembly, which in turn, drives the power generator. A control system is used to detect water conditions and to selectively adjust the length of the support structure and the fluid flow characteristics to dynamically optimize power generation based on changing water conditions.

A system and method for efficiently charging and discharging a capacitive load from a single voltage source. The system includes a first switch for selectively connecting the voltage source to the load and a second switch for selectively providing a short across the load as may be common in the art. A particularly novel aspect of the invention resides in the provision of plural capacitive elements and a switching mechanism for selectively connecting each of the capacitive elements to the load whereby the load is gradually charged or discharged. In the illustrative embodiment, the switching mechanism includes a set of switches for selectively connecting each of the capacitive elements to the capacitive load and a switch control mechanism for selectively activating the switches.

In the surface treated doctor blade of the present invention, it is possible to improve wear resistance of the blade edge end and to suppress generation of printing failures during continuous printing. Further, in the mode in which at least a part of the blade base material is exposed, it is possible to reduce running-in time for adjustment of contact of the blade edge with the cylinder after replacement of the doctor blade.
