In an active matrix semiconductor display device in which pixel TFTs and driver circuit TFT are formed on the same substrate in an integral manner, the cell gap is controlled by gap retaining members that are disposed between a pixel area and driver circuit areas. This makes it possible to provide a uniform cell thickness profile over the entire semiconductor display device. Further, since conventional grainy spacers are not used, stress is not imposed on the driver circuit TFTs when a TFT substrate and an opposed substrate are bonded together. This prevents the driver circuit TFTs from being damaged.

A portable electric fastening tool operating from a power supply. The motor moves a piston which compresses air against a sealed chamber. The piston is coupled to a fastener impacting anvil and is released after sufficient energy is stored in the air chamber. The air energetically expands pushing the piston and fastener driving anvil into the substrate. The actuation is governed by a control circuit and initiated from a trigger switch. The stored energy delivered from the motor is coupled to the output anvil and drives the nail. At least one position of the output anvil is sensed and once the nail is driven, the power can be disconnected from the motor. This method uses a rack and a pinion to drive the piston thus reducing wear and increasing efficiency of the device. Elastic bumpers are used at the end of the stroke to limit stresses during the impact. The electrical control circuit and sensors allow precise control and improve safety. An intermediate clutch is used to increase reliability and performance. The power supply is preferably a rechargeable low impedance battery pack.

A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, having a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system comprises a PID (Proportional Integral Derivative) controller or other pressure-sensing device that monitors the amount of pressure and volume within the balloon catheter.
