Abstract: A stick-type ignition coil to be directly connected to a spark plug via a spring. A high tension case containing a high tension terminal and a spring is integrally connected to the bottom end of a high tension generating portion of the ignition coil. The high tension terminal and the spring are separately supported in the high tension case before the spark plug is connected to the ignition coil. When the spark plug is connected, the spring is compressed and contacts the high tension terminal, thereby making electrical contact between the ignition coil and the spark plug. Since the spring and the high tension terminal are supported on separate positions in the case, the spring can be properly compressed without being distorted or jammed between the high tension terminal and the case.

Abstract: In a method for controlling an expiratory valve in a ventilator during expiration, the expiratory valve is opened substantially fully for a first interval. Fully opening the expiratory valve has the advantage of minimizing the expiratory resistance a patient needs to overcome. Keeping the expiratory valve open as long as possible during expiration, without losing control of positive end expiratory pressure (PEEP), is therefore advantageous. An optimal system is achieved. In a method wherein pressure in the expiratory section of the ventilator is measured during a second interval, the expiratory valve is regulated so a predetermined end pressure is obtained in the expiratory section, and at least one parameter, directly or indirectly related to control of the expiratory valve, is determined, and a determination is made from that parameter as to whether the next first interval for the next expiration should be longer than, shorter than or as long as the first interval.

Abstract: A method of using an ophthalmic surgical sponge is described. The sponge includes a base and a corneal shield assembly. The base allows absorption of corneal fluid during eye surgery. The corneal shield assembly is used as an absorption structure and a structure to protect the corneal cap which is formed during eye surgery, particularly in surgeries that remove tissue from the corneal stroma. The corneal shield assembly protects the corneal cap as well as the hinge of the flap during the actual tissue removal from either a laser or other tissue removing means. Thus, the corneal cap is protected from scatter rays from the laser or other debris created from tissue removal of the cornea. Wetting the ophthalmic sponge creates a co-hesive seal so that the corneal shield assembly can seal the corneal cap securely. This seal is removable after the surgery is completed to re-expose the corneal cap and replace the cap on the cornea.

Abstract: A self-adjusting venturi/mixer is disclosed. An inlet port body and outlet port body having a converging region and diverging region, respectively, are longitudinally slidably disposed with respect to each other, forming an annular injection gap that widens when the ports are moved apart and narrows when the ports are moved together. The movement is accomplished by virtue of varying fluid pressure at the inlet port, which exerts frictional pull on the outlet port, pulling the inlet port body away from the outlet port body. In other embodiments, a flexible member is positioned peripherially around the annular gap so that as the gap widens, the flexible member deforms to partially close the gap. This keeps the bubble size small where a gas is being injected into a liquid, and also limits a maximum flow of additive material at excessive flow rates.
