Patent ID-17864-A (ID)
Inventor: JOHNSON BRUCE C
IPC: A61F13/00
Filed: 1997-05-12
Abstract: A nasal dilator that prevents the outer wall tissue of the nasal passages of the nose from drawing in during breathing comprises a truss member. The truss member includes a flexible strip of material having a first end region, a second end region and an intermediate segment. The first and second end regions are adapted to engage the outer wall tissue of first and second nasal passages of the nose. The intermediate segment is configured to traverse a portion of a nose located between the first and second nasal passages, and a pad can be provided to prevent adhesion of the intermediate segment to the nose. The truss member further includes first and second resilient bands secured to the strip of material adjacent opposite edges of the intermediate segment. The resiliency of the first and second resilient bands acts to stabilize the outer wall tissue and thereby prevents the outer wall tissue of the first and second nasal passages from drawing in during breathing. Rather than a pad preventing adhesion, an adhesion reduction can be provided by a partial adhesion arrangement.

IPC: H05B3/12
Filed: 1978-01-09
Abstract: PURPOSE:To improve abrasion resistance and recordability by forming a heating resistor with two or more kinds of metal borides and oxygen. CONSTITUTION:The thin film heating resistor 2 on a substrate 1 composed of an electric insulator such as ceramics, glass or other is formed of two or more kinds of zirconium boride, hafnium boride, lanthanum boride, titanium boride, tantalum boride, niobium boride, tungsten boride, molybdenum boride, chromium boride and vanadium boride and oxygen in such a manner that the content of oxygen becomes 0.005 (atom ratio) or more of the total quantity of metals. Then if the specific resistance value is set high, the resistance value of electrode parts can be high to a certain degree and therefore production process becomes easy and the reduction in the thickness of electrodes results in less undulations of the surface hence improved abrasion resistance. Furthermore, the decreased voltage drop at the electrode parts leads to reduced uneven coloring densities owing to uneven heating.

Abstract: PURPOSE:To enhance the stability by eliminating the possibility of error in memory information by providing a constant current source which injects the current of a fixed value and a means of reducing the current of a value determined from an injected current by means of input control signals. CONSTITUTION:Only a current I1 of the constant current 201 is injected to the titled laser 200 at all times, and either one of amounts of emitted light of P0 or P1 is held to the laser 200. The laser 200 is set by giving an incidence light Pin having a light amount of Pt or more, and the amount of emitted light P1 is held even on removal of the light Pin. When a voltage V is applied to a control signal input terminal 203, a transistor 300 turns on, and most of the current I1 flows into the collector of the transistor 300. The laser 200 is reset and helds the amount of emitted light P0 even when the control input voltage becomes 0. The factor of memory information error becomes only the variation in current I1 of a constant amount source 201, and stable action can be performed.
