Provided is a CAN system that can generate an error signal without requiring hardware for generating an error signal to be connected to a bus. A protocol processing part within a CAN controller incorporates error data into receive data or send data, based on error data information stored in a register.

There are provided an evaluating system of a robot and its evaluating method capable of measuring a movement state amount, particularly, a position or a speed or an acceleration, or an angle or an angular speed or an angular acceleration of an arm of a robot by a simple system constitution in noncontact, accurately, in real time, dispensing with a complicated calibration. There is provided an evaluating system of a robot characterized in including a sensor provided at an arm of a robot for detecting a movement state amount of the arm, an angle detector for measuring an articulate angle of each axis servo motor of the robot, a first sensor operating portion for converting a state amount of the sensor into a state amount in a robot coordinate system, a second sensor operating portion for converting an articulate angle of the angle detector into a state amount in the robot coordinate system, and an output synthesizing portion for synthesizing an output of the first sensor operating portion and an output of the second sensor operating portion.

An interferometer includes a waveguide core, and thin film heaters with widths W1 and W2. The thin film heaters are mounted directly above the waveguide core, and operate as two types of different annealing regions. The annealing, which is carried out by supplying current to the thin film heaters, can alter the quality of the cladding, and change the stress applied on the waveguide core, thereby making it possible to control the polarization dependency. Thus changing the width of the thin film heaters and/or the amount of the supply current thereto enables the permanent control of the effective refractive index (birefringence index) independently in the transverse electric polarization mode and the transverse magnetic polarization mode. This enables the transverse electric polarization mode to be adjusted to a phase difference of &lgr;/2, and the transverse magnetic polarization mode to a phase difference of zero.

In a light waveguide circuit including a plurality of waveguides having different length, a material (10) having a temperature coefficient of a refractive index including a symbol different from that of a temperature coefficient of an effective refractive index of the waveguide (4) is charged into a groove (12) formed by removing the upper clad and the core from the waveguide (4), or a groove (12) formed by removing the upper clad, the core and the lower clad from the waveguide (4). A difference in length of the removed portions between adjacent waveguides is proportional to a difference in length of the waveguides which were not removed and remained.

This invention refers to a liquid crystal device that provides a color display by utilizing a colorization phenomenon caused by double refraction birefringence of a liquid crystal, wherein the color tone that appears when no voltage or a non-selected voltage is applied is white or a non-color close thereto, and at least two colors are displayed when a voltage is applied, and electronic equipment in which this liquid crystal device is installed. A liquid crystal device which is capable of displaying colors without using color filters and which is also capable of displaying white or a non-color close thereto is implemented by optimizing the value of .DELTA.n.multidot.d of the liquid crystal and the relationship between the value of .DELTA.n.multidot.d of the liquid crystal and the value of retardation (R) of an optically anisotropic substance such as a retardation film. In other words, the liquid crystal cell and the optically anisotropic substance should be such as to satisfy the following relationships: .DELTA.n.multidot.d.gtoreq.1(.mu.m) 15.5.times..alpha..sup.2 -40.times..alpha.+25.1.ltoreq.R-.DELTA.n.multidot.d.ltoreq.15.5.times..alpha..sup.2 -40.times..alpha.+25.8(.mu.m)
摘要:
A process for exhaust gas desulfurization by the wet lime-gypsum process comprises an absorption step for scrubbing the exhaust gases with a calcium hydroxide slurry as an absorbent; an oxidizing step for oxidizing a slurry composed chiefly of calcium sulfite from the absorption step; and a solids-liquid separation step for separating a slurry composed mainly of gypsum from the oxidizing step, characterized in that the liquid from said solids-liquid separation step is passed into a sulfate impurity reaction step where said liquid reacts with added calcium hydroxide and is thereby freed from water-soluble sulfate impurities; and the so purified liquid is supplied to the absorbent preparation step where it is mixed with calcium hydroxide to form said absorbent. Also, precipitates formed in said sulfate impurity reaction step are supplied to said absorbent preparation step.
