Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a path change-over system which returns a default route from a congested state by switching a packet transfer path that becomes a congestion factor to a short-cut path when a default route is congested in an MPOA network. SOLUTION: A congestion detecting part in each router 11 to 14 on a default route supervises the states of a transmitting buffer and a receiving buffer which are provided in each interface that is held by each router. As a result of supervision, when congestion is detected, a congestion notification message is transferred through an NHRT control path or an MPOA control path. An edge device 21 which receives the congestion notification message uses a target protocol address and switches to a short-cut path that is performed by an MPOA protocol.

Title: Filter of photoelectric touch panel
Inventor: SASAKI HIROAKI
IPC: G06F3/041
Filed: 1985-04-18
Abstract: PURPOSE:To prevent the malfunctions of a filter by forming this filter into a taper shape opening to outside and therefore eliminating reception of the reflected light. CONSTITUTION:A filter 10 is formed into a taper shape opening to outside at an about 45 deg.. Thus the taper surfaces 11 are formed on the surface of the filter 10. These surfaces 11 reflect the light diffused toward a filter 10b orthogonal to a filter 10a set at the front of an LED3 toward outside mainly by the light given from the LED3 provided at the end of an array 2. Then only the light traveling straight is received by a phototransistor 4 set opposite to the LED3. Thus only the light traveling straight is received by a photoreceptor with no reception of the reflected light. Therefore the cut-off matrix-shaped infrared beams is supplied accurately to avoid malfunctions of the filter 10.

Filed: 1993-04-09
Abstract: PURPOSE:To prevent dirt from reaching a condenser lens and suppress an increase in the absorptivity of light rays and to prevent heat from being generated and prolong the life by holding the pressure in a holder main body higher than the outside with air sent from an air blowing part, and discharging the air. CONSTITUTION:The air sent in from an air supply cylinder 13 is jetted from an air hole 11 to the condenser lens 2, and the air forms an air flow which moves toward an incidence opening 3 after being blown to the condenser lens 2, and passes over the top surface of the condenser lens 2 from the air hole 11 to reach the incidence opening 3. Therefore, the lens holder 10 has the air flow which removes heat to cool the condenser lens 2 when the air blown out of the air hole 11 comes into contact with the condenser lens 2 and moves out of the incidence opening 3, thereby preventing fumes, etc., from entering the lens holder body 12 through the incidence opening 3. Consequently, the lens holder 10 prevents fumes, etc., from being deposited on the top surface of the condenser lens 2 and prevents the absorptivity of the laser light from increasing.

An incident angle of the light beam which is made incident on the walls 95, 97 from the optical emitter 55 is an angle between a Brewster's angle and 90 deg. measured from a normal, therefore, only its small part is refracted into the walls 95, 97, its greater part is reflected, and accordingly, the light beam is propagated to the light spot 75. The light beam from the optical emitter 55, which is propagated through the channel 65 forms a light spot whose range has been determined distinctly, on an image surface 81.

Abstract: PURPOSE:To maintain high refining power and to reduce the expense of slag by specifically combining fluoride or chloride of an alkaline earth metal, Fe or Ni oxide, etc. with an Na or K compound to prepare slag while reducing the amount of the Na or K compound used. CONSTITUTION:Dephosphorization is performed with slag consisting of, by wt., 30-70% fluoride and/or chloride of an lakaline earth metal, 1.0-30% of >=1 kinds of compounds selected from oxides and carbonates of Na and K, 5-50% Fe and/or Ni oxide and 0-<40% oxide and/or carbonate of an alkaline earth metal. The Si content of molten pig iron contg. >=3% Cr is kept <=0.2wt% and brought into contact with said slag while inhibiting the oxidation of Cr. Si is oxidized preferentially and hinders the oxidation of P, so less Si is desired. Said slag has a low m.p. and high solubilizing power. It dissolves the Na or K compound stably, controls the evaporation loss of the compound, and increases the reaction efficiency considerably.

Abstract: PURPOSE:To generate perpendicular magnetic anisotropy and to permit formation of a high-density magnetic recording medium by forming an etching mask on the surface of a thin magnetic material film on a substrate and etching the thin film by using this mask. CONSTITUTION:The etching mask 13 is formed on the surface of the thin magnetic material film 12 on the substrate 11 and the thin film is etched by the mask 3, by which magnetic material projections of very small diameters consisting of the thin film 12 are bristled at the decreased magnetic interactions with each other. The effect of shape magnetic anisotropy is added in addition to the crystal magnetic anisotropy intrinsic to the medium when the shapes of such magnetic material columns are taken into consideration and, therefore, the large perpendicular magnetic anisotropy is artificially created. The production of the novel perpendicular magnetic memory is thereby permitted.

Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic head and a method for measuring the amount of a levitation of the magnetic head whereby the float amount between a glass disk and a slider coated with a protecting film can be highly accurately measured. SOLUTION: An area 12A without a protecting film is arranged at a part of a protecting film 12 applied to an air bearing face 11. A spot light is projected to a slider 10 levitating from on a rotating glass disk 100. Resulting reflection information (each reflection information from the non applied area and the protecting film-deposited area of the slider) and reflection information from a face of the opposing glass disk 100 are measured. Each levitation amount at the applied area and the non applied area of the slider is operated based on the reflection information. Thereafter, a correct levitation amount at the applied area is calculated based on the levitation amount at the non applied area and a thickness information (t) of the protecting film.
