摘要： Methods are provided for assembling a magnetic encoder wherein fluctuation of a magnetic gap arising from a change in temperature is minimized. The magnetic encoder comprises a magnetic scale having thereon a magnetic pattern which can be detected by a magnetic sensor, a sensor retainer for securely retaining the magnetic sensor with a magnetic gap left between the magnetic scale and the magnetic sensor, and a supporting member to which the sensor retainer is secured.According to the invention, a jig is affixed to a surface of the sensor retainer, and the jig is moved until the gap between the magnetic scale and the magnetic sensor reaches a predetermined width. The sensor retainer may be secured to a supporting member by first and second securing agents, the second securing agent being the harder and applied closer to the magnetic sensor than the first securing agent.

摘要： Herein disclosed is an optically reflecting code plate having a number of reflective and unreflective portions formed alternately on the surface of its substrate. This substrate is made of aluminum of high purity, for example, and has its surface anodized with a colorless, transparent and porous aluminum oxide film. At predetermined positions of the oxide film, which are to be formed with the aforementioned unreflective portions, moreover, metal such as nickel, tin, copper, iron, cobalt, silver, manganese or selenium is deposited by electrodeposition in the bottoms of the pores of the oxide film thereby to form a metal-deposited layer. Moreover, the vicinities of the openings of the aforementioned pores are impregnated with a dye such as a black metallized complex salt dye or a Nigrosine dye to form a dye-impregnated layer. The aforementioned metal-deposited layer and the dye-impregnated layer are overlaid the later over the former thereby to form the unreflective portions. The remaining portion shaving neither the metal-deposited layer nor the dye-impregnated layer so that it is exposed directly to the outside is left as the reflective portions.
