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).

A process cartridge includes an image bearing member, a brush, and a supporting portion. The brush includes a base member having an elongated plate shape that extends in the longitudinal direction, a brush member including bristles provided on the front surface of the base member, and mounting portions formed at both latitudinal ends of the base member. The supporting portion includes holding portions that hold the mounting portions formed at the both latitudinal ends of the base member, thereby supporting the brush with respect to the image bearing member.

A code reading pattern and an image pickup apparatus are provided for reading a symbol representing significant information, the symbol encoded by the pattern. The code reading pattern is formed by repeated markings of constant pitch on the surface of an object. The markings define area having at least one boundary, the at least one boundary defining an outline of the symbol. The apparatus includes a lighting system for illuminating the code reading pattern with parallel light, an imaging system for imaging light reflected from the pattern, a spatial frequency filtering system, located at the near back focal plane of the imaging system, for blocking regular reflected light and for transmiting diffracted light to project an image of the symbol, and a receiver for receiving the image.

In a reflective photosensor in which a light emitting element and a light receiving element are disposed in a mold resin, a planar optical element (micro Fresnel lens) including a first lens section for projecting a light emitted from the light emitting element toward a sense object in an external space and a second lens section for introducing a reflection light reflected from the sense object to the light receiving element is arranged in the mold resin. Favorably, the light emitting element is a light emitting diode of an edge emitting type and is set in a posture in which the element lies on its side. A reflection mirror is disposed in the model resin to introduce a light emitted from the light emitting diode to the first lens section.

摘要:
In an ice making machine having a water plate pivotally supported by a support shaft in such a manner that the water plate is raised to an ice making position just below an ice forming evaporator unit during the freezing cycle of operation and lowered to a discharge position during the harvest cycle of operation, and a suspension mechanism which is arranged to suspend the water plate in place and is operated by an electric motor assembled therein to raise or lower the water plate, an electric control apparatus for the ice making machine is arranged to measure lapse of a first period of time during which the water plate is lowered by activation of the motor from the ice making position to the discharge position, to measure lapse of a second period of time during which the water plate is raised by activation of the motor from the discharge position to the ice making position, to determine as to whether or not each lapse of the first and second periods of time becomes more than a permissible period of time, to produce an output signal therefrom when each lapse of the first and second periods of time has become more than the permissible period of time and to deactivate the motor in response to the output signal.
摘要:
A color cathode-ray tube where an electron beam selection mask with an aperture grille type beam selection electrode of a thin metal plate attached to a frame is supported by engagement of stud pins with support springs and is thereby positioned stably opposite to a color luminescent screen formed on the inner surface of a panel. A projection is formed on either the top of each stud pin or the bottom of each cap opposed thereto, while a recess is formed in the other for engagement with the projection in the direction orthogonal to the action of the support spring. The mutual contact portions of such projection and recess are coated with solid lubricant films so that the beam selection mask can be reset at its proper position despite any external impact applied thereto. The elasticity constant of the frame is selectively set at a desired value with additional disposition of reinforcing plates having the same thermal expansion coefficient as that of the frame, thereby averting vibration of the beam selection mask. And rotary mechanisms are formed relative to the support springs and are rotated in accordance with thermal expansion of the frame, so that the frame is shifted toward the panel surface having a color luminescent screen thereon, whereby mislanding of the electron beam due to temperature rise in the beam selection mask can be prevented.
