Title: Magnetic encoder
Inventor: SHIMAOKA HITOSHI
IPC: G01D5/245
Filed: 1990-11-30
Abstract: PURPOSE:To eliminate the need for gap adjustment and reduce a change in detected output by putting a magnetic sensor in elastic contact with the magnetic pattern portion of a magnetic rotor. CONSTITUTION:A magnetic pattern is magnetized at preset pitches on the outer- periphery slide face 20 of a magnetic rotor 1 which is molded with mixed plastic and magnetic powder. A magnetic induction layer 3, filmed on the surface of a sensor substrate 5 with Ni, Fe, Co, etc., which has the surface coated with a ceramic or fluorin resin wear-resistant layer 2 for protection is put in slide contact with the slide face of the rotor 1 by a plate spring at a sensor holder 8. In addition, slight vibration during a high speed run of the rotor 1 is absorbed by a buffer 6 put in contact with the holder 8. In this way, the induction layer 3 is arranged in consistently uniform slide contact with the magnetic pattern of the rotor 1, allowing a less change in an output signal from the magnetic sensor as a result of a change in a gap to the rotor 1 and other factors. Also, a lower cost is achieved because of no use of high precision parts.

Title: Rack bushing
Inventor: KANEMITSU HIROSHI
IPC: F16C33/20
Filed: 1990-11-30
Abstract: PURPOSE:To enhance the anti-abrasiveness of a rack bushing by forming it from a resin bearing material consisting of at least one out of the group, which comprises polyacetal, polyamide, polyphenylene sulfide, polybutyl telephthalate and super-highpolymer polyethylene, and also wiskers of Zn oxide. CONSTITUTION:The base of the resin bearing material for a rack bushing 1 is at least one of the polyacetal, polyamide, polyphenylene sulfide, polybutyl telephthalate, and super-highpolymer polyethylene. As wiskers of Zn oxide included in this base material assume the form of tetrapod, it is not required to take the directionality into consideration when the resin is left to injection molding, and this shape of tetrapod prevents exfoliation effectively. Thus stable anti-abrasiveness can be obtained.

Title: Flame-detecting apparatus
Inventor: YANAGAWA YOSHIKAZU
IPC: G01J1/42
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To facilitate detection of a non-luminous flame by transforming the coordinates of the color components of a color image of a flame part to coordinates of hue, saturation and luminance, binarizing each part of a predetermined value and detecting the presence of a flame from an obtained image. SOLUTION: A burner flame in a boiler is picked up by an image input part 1. An image of the flame is digital-converted and preserved in an image memory 3. An image operation device 4 transforms the coordinates of the color image to coordinates of a hue, a saturation and a luminance, and carries out an operation whereby a range of the hue corresponding to a color of the flame is extracted when the luminance and saturation are fixed values or larger, thereby detecting a flame part. The operation is separated into two of the cases when the neighborhood is dark and bright.  For instance, when the neighborhood is dark, an OR of an AND image of images obtained by binarizing a hue image, a saturation image and a luminance image of the color image under a predetermined condition and an image of a high luminance part of the luminance image is obtained and an extraction image of a flame region is obtained. Then, a total area of the flame region is obtained. When the total area is larger than a fixed threshold value, it is judged that the flame is present. When the total area is smaller, it is judged that the flame is distinguished.
