摘要： In an encoder signal interpolation divider (1) that automatically corrects errors in the offset and gain of an input signal at a high speed with a low cost circuit configuration, and can accurately generate an encoder signal having a predetermined resolution by interpolation division, analog input signals (A1, B1) are subjected to offset correction by a 0-point correction circuit (13) in adders (4, 5) prior to being digitally converted by A/D converters (8, 9), and are subjected to gain correction by an amplitude correction circuit (14) in amplifiers (6, 7). The corrected analog signals are converted to digital values, angle data is calculated in an angle data lookup table (10), and, based on these results, an encoder pulse signal having a predetermined resolution is generated and output from an encoder pulse signal generating circuit (12).

摘要： A projection-type linear encoder has a moving grating plate formed with a set of photodiodes for detecting an origin position and a reflective grating plate formed with reflective grating sections for detecting an origin position. The set of photodiodes for detecting an origin position includes photodiodes (5Z, 5Z1, 5Z′, 5Z1′) that are aligned in accordance with an alignment pattern produced using random numbers, and the reflective grating sections for detecting the origin position include reflective grating sections and non-reflective grating sections that are wider than grating sections for detecting an A phase signal and a B phase signal similarly disposed in accordance with an alignment pattern produced using random numbers. The origin position of the moving grating plate can be precisely detected based on a differential signal of photodiodes (5Z) and photodiodes (5Z′) and a differential signal of photodiodes (5Z1, 5Z1′) that differ in phase by 90° to the photodiodes (5Z, 5Z′).

摘要： A projection linear encoder has an SOQ substrate formed with transmission gratings and grid-like photodiode groups, and a reflecting grating plate with reflecting gratings that are formed facing thereto. A light-blocking film composed of a metal thin film or the like is formed on a surface of a glass substrate of the SOQ substrate, and the transmission gratings are formed by patterning the light-blocking film. The photodiodes are integrally formed by epitaxial growth on the silicon layer of the SOQ substrate. Transmission gratings with high mechanical strength can be formed inexpensively in comparison with cases in which through holes are formed by etching a silicon substrate to manufacture transmission gratings.

摘要： When a cover 18 closes an opening end surface 11d of a boss 11, an annular piece 18a moves close to an annular groove 20 to form a labyrinth structure, and thus a flow path for turbocharged air becomes narrower to produce air resistance, which causes the cover 18 to be hardly closed. Thus, chattering is prevented from occurring, and a relief valve 10 can be prevented from being damaged.

The resin layer includes a first surface that faces the surface of the transparent substrate; a second surface that faces away from the surface of the transparent substrate; and a plurality of projections arranged on the second surface of the resin layer so as to form a projection layer. Each of the plurality of projections has a cross section that includes an entire center axis perpendicular to the surface of the transparent substrate. Each of the plurality of projections has a cross section that is in a shape of quadratic function. An arranged pitch of each of the plurality of projections is not more than half of a wavelength of incident light. An aspect ratio of each of the plurality of projections is 1 or less. A difference between a refractive index n1 of the transparent substrate and a refractive index n2 of the resin layer satisfies the following expression: |n1−n2|≦0.05. A thickness of the resin layer is 11 μm or more. The plurality of projections are shaped and arranged so as to satisfy a linear relationship between an effective refractive index of the projection layer and a height of the projection layer.
