摘要:
Hydrogen ions are implanted to a surface (main surface) of the single crystal Si substrate 10 at a dosage of 1.5×1017 atoms/cm2 or higher to form the hydrogen ion implanted layer (ion-implanted damage layer) 11. As a result of the hydrogen ion implantation, the hydrogen ion implanted boundary 12 is formed. The single crystal Si substrate 10 and the low melting glass substrate 20 are bonded together. The bonded substrate is heated at relatively low temperature, 120° C. or higher and 250° C. or lower (below a melting point of the support substrate). Further, an external shock is applied to delaminate the Si crystal film along the hydrogen ion implanted boundary 12 of the single crystal Si substrate 10 out of the heat-treated bonded substrate. Then, the surface of the resultant silicon thin film 13 is polished to remove a damaged portion, so that a semiconductor substrate can be fabricated. There can be provided a semiconductor substrate in which a high-quality silicon thin film is transferred onto a substrate made of a low melting point material.

摘要:
An audio controlling device generates an audio mute signal based on the level of a power-supply voltage supplied from the source equipment, whether a clock signal has been input or not, whether a digital signal has been input or not, whether a multiplier circuit is being locked or not, an error rate, whether an audio clock detection circuit is being locked or not, the presence or absence of a change in a control signal, and whether a synchronization detection circuit is stable or not. The audio controlling device applies the audio mute signal to an audio mute circuit, while applying an OSD control signal to an OSD processing circuit. The audio mute circuit is placed in a mute state or unmute state based on the audio mute signal. The OSD processing circuit provides the on-screen display of a message based on the OSD control signal.

An endless metal belt including a ring formed by laminating endless metal plates; and multiple elements continuously attached to the ring. Each of the elements has a body, a head connected to the body by a pillar, and slots formed between the body and the head on left and right sides of the pillar, respectively, for receiving the ring. The elements satisfy the equations (h/t) 40, where h is a width of the slots, t is a plate thickness of the elements, and S is an area of the head.

A heating plate having a smooth surface is placed on a hot plate which constitutes a heating section, and the smooth surface of the heating plate is closely adhered on the rear surface of a single-crystal Si substrate bonded to a transparent insulating substrate. The temperature of the heating plate is kept at 200° C. or higher but not higher than 350° C. When the rear surface of the single-crystal Si substrate bonded to the insulating substrate is closely adhered on the heating plate, the single-crystal Si substrate is heated by thermal conduction, and a temperature difference is generated between the single-crystal Si substrate and the transparent insulating substrate. A large stress is generated between the both substrates due to rapid expansion of the single-crystal Si substrate, thus separation takes place at a hydrogen ion-implanted interface.

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.

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.
