This compound is useful for dyeing or printing fiber materials and gives a dyed or printed product having a color superior in various fastness properties with superior build-up property.
摘要:
Methods of treating or preventing axonal degradation in neuropathic diseases in mammals are disclosed. The methods can comprise administering to the mammal an effective amount of an agent that acts by increasing sirtuin activity in diseased and/or injured neurons. The methods can also comprise administering to the mammal an effective amount of an agent that acts by increasing NAD activity in diseased and/or injured neurons. Also disclosed are methods of screening agents for treating a neuropathies and recombinant vectors for treating or preventing neuropathies.

In an in-the-ear hearing aid provided with a pull-out type linear member, a housing section is provided to house a pull-out type linear member 25. The housing section is a guide tunnel 24 penetrating a case body 23. The pull-out type linear member 25 is provided, at both ends, with small bulges 25a and 25b. The pull-out type linear member 25 is provided in such a manner that the front small bulge 25b is located outside the guide tunnel 24 and the rear small bulge 25a is located inside the guide tunnel 24. A small diameter port 24a is provided at an opening section of the guide tunnel 24 to serve as a stopper for the rear small bulge 25a.
摘要:
An optical coupler having a Y-branch operable to mix and output a first light and a second light from outside. The optical coupler includes: a first input optical wave guide operable to propagate the first light from outside; a second input optical wave guide operable to propagate the second light from outside; an optical coupler operable to output a mixed light, which is a mixture of the first light and the second light; and an output optical wave guide operable to propagate the mixed light and to output it from an end, wherein percentage per unit length of emitting light being propagated in the output optical wave guide to a periphery of the output optical wave guide is higher than that of the first input optical wave guide or the second input optical wave guide.

A processor, a task management table, and a scheduler are built in a microcontroller. The processor sequentially runs a plurality of tasks for controlling hardware engines (cores) respectively allocated thereto. The task management table stores task management information which includes state information (ST INFO) representative of the execution state of each task, priority information (PRI INFO) representative of the execution priority of each task, and core identification information (CID INFO) representative of the allocation of the tasks to the cores. The scheduler allows the processor to switch between tasks on the basis of the task management information when a given instruction is decoded or when the execution of any one of the cores is terminated.

摘要:
The present invention prevents the deterioration of electrophotographic photoreceptor properties due to non-uniform dissolution of the surface of an aluminum substrate or production of hydrates during rinsing or drying from hot pure water in an aqueous cleaning process, assuring the uniformity and stability on the surface of an electrically-conductive substrate for electrophotographic photoreceptor. The resulting electrically-conductive substrate for electrophotographic photoreceptor exhibits an excellent corrosion resistance that can be expected to provide a high environmental stability. Further, the resulting electrophotographic photoreceptor can exhibit improved electrical properties. The present invention provides a novel electrically-conductive substrate for electrophotographic photoreceptor comprising aluminum or aluminum alloy, wherein the element ratio of aluminum in metallic form to aluminum in oxide form on the surface of said substrate as determined by X-ray photoelectron spectroscopy is 1:1 to 1:2.5 and the element ratio of aluminum to phosphorus on the surface of said substrate as determined by X-ray photoelectron spectroscopy is 1:0.02 to 1:0.1.
