Abstract: Many permanent magnets(18) and a plate spring(19) are newly installed inside a Dot Matrix Head.  When an armature is pulled by electro- magnetic force, the spring(19) pushes the armature to increase the impact force of the armature.  On the contrary, when an armature is pushed by the coil spring(14), the permanent magnetic force of (18) pulls the armature to decrease the return time of armature, so clear, uniform printing and high speed printing are obtainable.  Both (18) and (19) greatly decrease the chattering and noises which occur between (11) and (13) at the return of the armature, and also protect the wear and tear of the armature and holder(11).

Abstract: A pulse oximetry system is provided in which LEDs (12, 14) of two different wavelengths illuminate tissue containing arterial blood flow. A photodiode (16) receives light from the LEDs and produces electrical signals (IR(t) RED(t)) containing pulsatile components. The components of the two wavelengths are separated and the pulsatile waveforms are monitored until signal peaks (IRmax) are detected at the end of diastole. The waveforms are then integrated over the systolic interval, and the integrals are combined with the signal peak values to determine an index value. The index value is used to select a value representative of oxygen saturation from a look-up table (36).

The etch barrier layer  (8) is a nitride film. Electrical isolation of the conductive material layers is maintained, not only during the rounding  process  which occurs for a portion of insulating film  (9)  overlying  the  etch barrier  layer (8),  but   also   in   the   presence   of   mask alignment/ excessive etching occuring  during  fabrication  of  the contact hole (20). The method prevents  the  current  leakage  and undesirable electrical short circuitry from generating.
