An optical scanning apparatus is configured to include a light source that emits a beam of light, and a scanning device that scans the beam of light in two axial directions that are mutually substantially perpendicular at a first frequency fH and a second frequency fL. The scanning device calculates the first frequency fH and the second frequency fL by using predetermined mathematical formulas, and scans the beam of light at the calculated first frequency fH and second frequency fL.
摘要:
A movable particle display (such as an electrophoretic display) in which a plurality of closed spaces are two-dimensionally disposed along a surface of the substrate, a plurality of particles contained in each of the closed spaces, and a reflection surface for reflecting light which enters each of the closed particles are moved inside a closed space, between a position at which they cover a reflecting surface and a position at which they are collected to expose the reflecting surface. At least a part of the reflecting surface diffusely reflects incident light with an intensity distribution having directional properties (i.e. non-isotropically). The intensity of the diffusely reflected light has an angular distribution such that: (1) the amount of light reflected toward the position at which the particles are collected is smaller than in the case when the distribution of diffusely reflected light is isotropic, and (2) the amount of light reflected away from the position at which the particles are collected is larger than that of light reflected towards that position.

An electrically controlled throttle apparatus comprises a throttle valve for controlling an amount of intake air to be supplied to an internal combustion engine; a throttle body which houses the throttle valve; a motor for driving the throttle valve; and a throttle sensor for detecting an opening degree of the throttle valve. The throttle sensor is a magnetic resistance element for detecting a change in direction of a magnetic field. The direction of the measured magnetic field of the throttle sensor when the throttle valve is in an opening learning reference position used as a criterion by the throttle sensor is the same as a direction of a leakage magnetic field of from the motor.
摘要:
A sensor for a throttle control device. The throttle control device includes a throttle body. A throttle valve is disposed within an intake air channel defined within the throttle body. A speed or gear reduction mechanism is coupled between a motor and the throttle valve. A sensor detects the rotational position, i.e., the rotational angle, of the motor and has a movable section and a fixed sensing section. The movable section is attached to a rotary shaft of the motor, so that the movable section rotates as the rotary shaft rotates. The fixed sensing section is mounted to the throttle body and is disposed within the movable section. By detecting the rotation of the motor a computing section can accurately determine the degree of opening of the throttle valve. The sensor outputs the degree of opening of the throttle valve.
摘要:
A system (apparatus and process) for producing an electrophoretic (display) device is provided for allowing production of such a device wherein charged phoretic particles in the dispersion liquid are easily and evenly distributed to respective cells (pixels) between two substrates of the device even in the case of a very small gap between the two substrates or the case of using a flexible substrate. The system includes a storage for a dispersion liquid containing the charged phoretic particles dispersed therein, a stirrer for stirring the dispersion liquid, a substrate-holder for holding the substrate in the dispersion liquid, and a voltage source for applying a voltage to the electrodes formed on the substrate thereby depositing the charged phoretic particles on the electrodes.
摘要:
A rotational angle sensor detects a rotational angle of a rotary member based on a magnet field produced across the rotary member by a pair of magnets. At least one magnetic detection device is disposed within a holder and serves to detect the magnetic field and to output a signal representing the rotational angle of the rotary member. For example, the holder may be mounted to a fixed place. A printed circuit board is coupled to the holder and is electrically connected to the at least one magnetic detection device. A positioning device serves to position the at least one magnetic detection device in a predetermine position relative to the holder.

A display device includes a first substrate and a second substrate disposed opposite to each other, and a display medium including an insulating liquid and electrophoretic colored particles dispersed therein and disposed between the first and second substrates. A first electrode and a second electrode are provided for applying a voltage to the display medium so as to move the colored particles between the first and second electrodes to effect a display depending on a voltage applied to the first and second electrodes. The electrophoretic colored particles are distributed uniformly without localization by incorporating the display medium in a plurality of light-transmissive tubes, and disposing and fixing the plurality of tubes in intimate contact with each other between the first and second substrates.
