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.

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.
