Abstract: Provided is an exhaust gas processing device for a diesel engine which can carry out sufficient regeneration processing of a DPF. A DPF regeneration control section continues normal regeneration processing by a DPF regeneration control section when an accelerated regeneration starting operation section does not perform accelerated regeneration starting operation after notification of accelerated regeneration requiring information is started. The DPF regeneration control section prohibits the normal regeneration processing, and an accelerated regeneration re-requirement notification section starts notification of accelerated regeneration re-requiring information, when a PM accumulation amount estimate becomes equal to or higher than an accelerated regeneration re-requirement determination value J4.

Provided is a therapeutic agent for allergic rhinitis for 5-aminolevulinic acid-based photodynamic therapy (ALA-PDT) comprising 5-aminolevulinic acid (ALA) or a derivative thereof, or a salt of the 5-aminolevulinic acid or the derivative as an active ingredient, and used in ALA-PDT in which light having a wavelength of 400 nm to 700 nm is irradiated; and particularly provided is a therapeutic agent for allergic rhinitis in a locally applied solution form, a water-soluble ointment-dissolved form, a jelly-dissolved form, or the like.

Abstract: The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device (7), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device (4) is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device (7) is set to allow the automatic DPF regeneration process, the DPF regeneration control device (4) retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.

Abstract: It is to provide photodynamic therapy (PDT) and photodynamic diagnosis (PDD) which are suitable for the diagnosis and therapy of a part requiring a certain degree of deep penetration, such as subcutaneous cancer and lymph nodes surrounded by blood vessels and fat. This is solved by performing PDT and PDD targeting cancer by administering a composition comprising a photosensitizing agent such as a tetrapyrrole-based compound (photofrin, protoporphyrin IX, etc.) or ALAs such as 5-aminolevulinic acid (ALA), ALA methyl ester, ALA ethyl ester, ALA propyl ester, ALA butyl ester, ALA pentyl ester, or a hydrochloride, phosphate, or sulfate thereof followed by irradiation with excitation light at a wavelength of 480 to 580 nm.

Abstract: An exhaust gas processing device for a diesel engine includes a DPF, a PM deposition amount estimating unit for PM deposited in the DPF, a DPF regenerating unit, a DPF regeneration control unit, a storage unit, an acceleration regeneration request information notifying unit, an acceleration regeneration start operating unit, and a mode selecting unit. When a normal regeneration process is selected, the time at which acceleration regeneration request determination reserve period T1 elapses from the start of the normal regeneration process without the end of the normal regeneration process is time T2 for acceleration regeneration request determination, at which time, if the PM deposition amount estimation value is greater or equal to acceleration regeneration request determination value J2, it is determined that there is the acceleration regeneration request.

Abstract: Provided is an exhaust-treatment device for a diesel engine, said device being capable of suppressing engine noise. In a first stage P1 of an exhaust-temperature-raising process, a target engine speed is set to a prescribed first target speed R1 and an intake throttle valve 41 is set to a prescribed first degree of opening O1. In a second stage P2, the target engine speed is maintained at the first target speed R1 and the intake throttle valve 41 is set to a position more closed than the first degree of opening O1. When a set duration T2 for the second stage P2 has come to an end, the intake throttle valve 41 is at a second degree of opening O2, which is maintained in third and subsequent stages P3/P4. In said third and subsequent stages P3/P4, as a set duration T3/T4 for each stage P3/P4 passes, the target engine speed is updated to a target speed R2/R3 higher than the target speed R1/R2 during the immediately prior stage P2/P3, and the temperature of DPF1 upstream exhaust gas 12 is increased.

Abstract: An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate. In order to achieve the object, DPF regenerating mode switch manipulation means (7a) switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode (51) or an acceleration-sole regenerating mode (52), and DPF regenerating selection manipulation means (7b) switches a position to a normal regenerating permission position (53), a normal regenerating cancel position (54), or an acceleration regenerating execution position (55). When the DPF regenerating mode is in the acceleration-sole regenerating mode (52), the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means (7b).

Abstract: A system visually distinguishes diseased tissue from healthy tissue after a treatment is administered to a patient to provide different concentrations of a fluorescent marking substance between the diseased tissue and the healthy tissue. A light source illuminates the tissue with excitation light. A detector detects light returning from the tissue, and a controller characterizes the returning light according to a measured property indicative of the different concentrations. A light projector projects light having a predetermined cue in response to the characterization of the returning light.

Abstract: The present invention has an object to provide an exhaust-gas processing device for a diesel engine, able to inhibit the deterioration of the fuel-consumption and the output reduction. In order to accomplish the above object, the device is provided with a DPF, a means for presuming the amount of PM to be deposited on the DPF, a DPF-regeneration means, a DPF-regeneration control means, a storing means, a means for sending message to demand an accelerated regeneration, and an operation means for starting the accelerated regeneration. While a normal regeneration processing is being continued (S6) since it has started (S2), the time when a term (T1) for reserving judgment as to the demand for accelerated regeneration has elapsed is taken as the judging time (T3). At this judging time (T3), if the assumed value of the PM deposed amount exceeds a value (J2) for judgment as to the demand for accelerated regeneration, the accelerated regeneration is deemed to be demanded.
