摘要： Present invention provides an optical encoder capable of improving the precision of an interpolation angle in a single signal track, in an encoder of sine-wave angle interpolation type. The optical encoder includes a waveform, in which a phase-modulated wave is superimposed in a predetermined period over a sine-wave of a fundamental period, as a signal track (103), and an optical detector (104) for extracting the sine signal and the cosine signal of the phase-modulated wave. An operation unit (106) operates electric angles individually from the output signals of a first optical detector pair and a second optical detector pair belonging to the optical detector, and determines the sum and difference of the electric angles, thereby acquiring the electric angle and the phase-modulated wave of the fundamental period.

摘要： An optical encoder includes: an optical scale having periodical optical patterns and can be relatively and angularly displaced; a projector for irradiating the optical scale with light; a light receiver for receiving light from the optical scale; and a calculator for calculating an absolute rotation angle θ of the optical scale in accordance with a signal from the light receiver. The optical patterns include a plurality of light shielding portions and a plurality of light transmitting portions, each of the portions being located alternately. When a pitch of an n-th light shielding portion in a predetermined circumferential direction is denoted by Pn and a width of the n-th light shielding portion is denoted by Wn, a transmissivity T(θn) corresponding to an angle θn of the n-th light shielding portion and the pitch Pn of the light shielding portion satisfy predetermined equations, and the width Wn of the light shielding portion in the optical pattern varies in accordance with a function of the pitch Pn of the light shielding portion.

摘要： A bonded member includes at least two members. The at least two members include a first member and a second member bonded to each other. The first member has a bonded face bonded to the second member. The bonded face has a recessed portion at an outer periphery of the bonded face, to retain an adhesive. The recessed portion is open at the bonded face and an outer peripheral face of the first member. In a plan view from a direction vertical to the bonded face, an outer edge of a bottom face of the recessed portion is disposed at an inner position in an in-plane direction of the bonded face than an outer edge of the outer peripheral face of the first member.

摘要： Incinerator apparatus includes a furnace and a chimney in communication with the furnace. Within the furnace, a pipe having a bore and extending upward from the bottom of the furnace is disposed. The pipe is in communication with atmospheric air at the lower end thereof and is provided with a plurality of air holes therein. The pipe also includes a top air hole at the top end thereof. The top air hole has a transverse cross-sectional area smaller than that of the bore of the pipe. External air is spontaneously introduced from the outside of the furnace and flows out through the top air hole. As air flows out of the top air hole, it is also uniformly distributed through the air holes into the furnace and garbage to be burned in said furnace.

摘要： A liquid crystal display device includes a pair of insulating substrates bonded to each other via a sealing material, and liquid crystal filled between a pair of the insulating substrates. A cell gap is formed so as to gradually increase from the center to an end of a display area at room temperature. According to this arrangement, it is possible to smooth out a difference in thermal expansion between the liquid crystal and the sealing material when an atmospheric temperature rises, and it is possible to prevent a cell gap from being too large in the center of the display area. Consequently, an irregular display color can be eliminated.
