In a control apparatus for use in a multiple light projection type image display apparatus, the control apparatus includes a light source driver part configured to drive a plurality of light sources; and an apparatus controller configured to control the light source driver part. The light source driver part drives the plurality of light sources at respective different frequencies.

A discharge lamp lighting device includes a lamp current control portion that generates, in synchronization with an input video signal, a control signal for controlling polarity reversal of an AC current with a steady-state lighting frequency and an AC current with a low frequency, and a lamp driving portion that drives the discharge lamp based on the control signal that is output by the lamp current control portion. The lamp current control portion generates a control signal for a brightness reduction waveform with timing corresponding to polarity reversal of the AC current with the steady-state lighting frequency, and the lamp driving portion inserts a current reduction waveform into the AC current with the low frequency by decreasing a voltage applied to the discharge lamp based on the control signal for the brightness reduction waveform. It is possible to reduce flicker that could be perceived due to insertion of a period without a reduction of the projection light amount (a period without a polarity reversal at the low frequency) during repeated reductions of the projection light amount occurring at intervals of polarity reversal of the steady-state lighting frequency.

The polarity of a voltage applied to the electrode pair is inverted by a changing signal generated at every boundary area of each filter color of the color wheel, and also in the blue color region (B) (a, b. c). Herewith, time during which the lamp electrode is positive and that negative is equal to each other every time the color wheel makes two rotations (T), thereby maintaining the heat load to be evenly distributed between both of the electrodes.

A display apparatus, which makes one pixel displayable in four colors, that is, three primary colors and a white color, and inputs and displays chrominance signals corresponding to a mixing ratio of the four colors, includes a color correction instrument which performs first color correction of increasing the saturation of chrominance signals, and a second color correction of decreasing at least the saturation of the chrominance signals, when a predetermined color component exists in the chrominance signals corresponding to a pixel, selection instrument which switches temporally and selects either of first chrominance signals obtained by the first color correction, and second chrominance signals obtained by the second color correction, and a display instrument which displays the chrominance signals, which are selected, in the pixel.

When a call instruction or interrupt branch is executed by a CPU, its return address is pushed to a stack memory. When a return instruction is executed, the pushed return address is popped from the stack memory. When a return instruction is executed by the CPU, a comparator compares the branch address output from the CPU and the address output from the stack memory. As a result of the comparison, if the addresses match, the branch address is not output as trace information. If the addresses do not match, the address register receives the branch address from the CPU and outputs the received branch address as the trace information.

The present invention aims at providing a debugging mechanism capable of detecting erroneous read access to a bus slave caused by a synchronization control infringement between bus masters due to a failure of software. Each of a dirty detector and a coherency error detector is used as a detector for monitoring a bus control unit and, during a period that write access corresponding to optionally designated conditions is present on a write buffer, detecting read access corresponding to conditions equal to the aforementioned conditions. A bus master includes a debugging unit. The debugging unit receives a coherency error notification from the coherency error detector to generate a debugging event, breaks an operation of the bus master, and performs various debugging operations while using the debugging event as a trigger.

The radioactive iodine compound of this invention or an intermediate for preparing the compound is represented by the following formula (I): ##STR1## wherein R is H or .sup.125 I. The radioactive compound can readily introduce a radioactive isotope element such as .sup.125 I into an antibody molecule without damaging the activity of the antibody molecule. Therefore, the compound can preferably be used to label an antibody of immunoradiometric assay, and allow a higher degree of measurement sensitivity.

A novel porous, weakly acidic, itaconic acid ion exchange resin and a process for its preparation are disclosed. The process comprises the copolymerization of the beta-monoalkyl ester of itaconic acid and a cross-linking agent such as divinyl benzene in the presence of a pore forming agent selected from the group consisting of aliphatic hydrocarbons of from 5 to 8 carbon atoms, alicyclic hydrocarbons of from 5 to 8 carbon atoms and halogenated hydrocarbons of from 1 to 3 carbon atoms, followed by hydrolysis of the resulting copolymer. The macroreticular itaconic acid ion exchange resin of this invention is characterized by an excellent combination of exchange capacity, heavy metals capturing capacity, ion exchange rate and gas adsorptive capacity.
