A muffler structure capable of suppressing generation of abnormal noise in the muffler even when the outer and the inner tubes expand thermally. Provided is a double-pipe muffler structure including an inner tube and an outer tube. In the muffler structure, an annular front step portion and an annular rear step portion are formed in the inner tube, while the step portions is brought into contact, from inside, with the outer tube and thus are supported by the outer tube. The outer tube supports the front and the rear step portions by being brought into close contact with the step portions partially and elastically.

Provided is a test apparatus that tests fluctuation of a power supply voltage supplied to a device under test, including an oscillator that outputs a clock signal having a frequency that corresponds to the power supply voltage supplied to the power supply input terminal of the device under test, and a measuring section that measures the frequency of the clock signal. For example, the oscillator outputs as the clock signal an output signal of any one negative logic element from among an odd number of negative logic elements connected in a loop, and at least one of the negative logic elements operates using, as a voltage source, a voltage corresponding to the power supply voltage supplied to the power supply input terminal of the device under test.

The present invention provides a screening method for a compound capable of inducing regulatory T cells, comprising the following steps:(1) a step for culturing CD4+ T cells having a naïve phenotype in the presence of a test compound, and isolating T cells from the culture product; (2) a step for evaluating the immunosuppressive function of the T cells isolated in the step (1); (3) a step for obtaining the foregoing test compound as a compound capable of inducing regulatory T cells if the results of the evaluation in the step (2) show that the T cells isolated in the step (1) have immunosuppressive function. The present invention also provides a method of producing regulatory T cells, comprising culturing CD4+ T cells having a naïve phenotype in the presence of a rapamycin compound to obtain regulatory T cells. The regulatory T cell produced by the method can be used as an immunomodulator for the prophylaxis or treatment of the rejection in organ transplantation, an allergic disease, an autoimmune disease, a graft-versus-host disease (GVHD), infertility and the like.

The input of a prescribed type information element is received from an operator via an operator interface. A first storage system outputs a first type information element required to construct a remote copy environment. A second storage system inputs second setting information, which comprises first type information elements and prescribed type information elements, uses the second setting information to execute a second setting, and outputs the second type information element required to construct a remote copy environment. The first storage system inputs first setting information, which comprises the second type information element, and uses the first setting information to execute a first setting. Since the types of information elements required to construct a remote copy environment are exchanged between the storage systems, the number of types of information elements inputted by the operator are less than the number of types of information elements required to construct the remote copy environment.

A silicon layer having a conductivity type opposite to that of a bulk is provided on the surface of a silicon substrate and hydrogen ions are implanted to a predetermined depth into the surface region of the silicon substrate through the silicon layer to form a hydrogen ion-implanted layer. Then, an n-type germanium-based crystal layer whose conductivity type is opposite to that of the silicon layer and a p-type germanium-based crystal layer whose conductivity type is opposite to that of the germanium-based crystal layer are successively vapor-phase grown to provide a germanium-based crystal. The surface of the germanium-based crystal layer and the surface of the supporting substrate are bonded together. In this state, impact is applied externally to separate a silicon crystal from the silicon substrate along the hydrogen ion-implanted layer, thereby transferring a laminated structure composed of the germanium-based crystal and the silicon crystal onto the supporting substrate.

To obtain a semiconductor substrate having a high-quality Ge-based epitaxial film in a large area, a SiGe mixed crystal buffer layer and a Ge epitaxial film is grown on a main surface of a Si substrate 10. Although high-density defects are introduced in the Ge epitaxial film 11 from an interface between the Ge epitaxial film 11 and the Si substrate 10, the Ge epitaxial film is subjected to a heat treatment at a temperature of not less than 700° C. and not more than 900° C. to cause threading dislocations 12 to change into dislocation-loop defects 12′ near the interface between the Ge epitaxial film 11 and the Si substrate. A main surface of at least one of the Ge epitaxial film 11 with an ion implanted layer and a support substrate 20 is then subjected to a plasma treatment or ozone treatment for the purpose of surface cleaning, surface activation, and the like, after which the main surfaces of the Ge epitaxial film 11 and the support substrate 20 are appressed against and bonded to each other with their surfaces being determined as the joint surfaces. An external impact is then applied to the bonding interface, causing the Ge epitaxial film to be delaminated along a hydrogen ion implanted interface 13, thus obtaining a Ge thin film 14. A surface of the Ge thin film 14 is subsequently subjected to a final surface treatment (for example, CMP) to remove the damage caused by the hydrogen ion implantation, thus resulting in a GeOI substrate having the Ge thin film 14 on the surface thereof.
