摘要:
It is an object of the present invention to apply a novel method of preparing neural cells from ES cells. The method of the present invention is characterized by the electric pulse treatment of differentiating ES cells. Nerve cells obtained by the method of the present invention have the flexibility to differentiate into a variety of types of neurons in vivo preferably without the need for application of growth factors.

A nose pad for camera includes a base plate, at least one projecting portion mounted to the base plate, and a sheet portion mounted to an edge of the base plate at an edge of the sheet portion and extending obliquely upwardly over the base plate and the sheet portion. The projecting portion has an arc shape so that the nose pad can fit a contour of a nose. The sheet portion is designed to have a reasonable space in between the sheet portion and the projecting portion, so that the nose of the user can softly touch the camera when the nose pad is used.

A VCSEL includes a first distributed Bragg reflector (DBR) of a first conductivity type formed on a substrate and including at least one semiconductor layer to be oxidized, an active region having a column shaped structure and formed on the first DBR, and a second DBR of a second conductivity type. At least one hole starting from a surface of the first DBR and reaching the at least one semiconductor layer to be oxidized is formed in the first DBR outside of a column shaped structure of the second DBR. An oxidized region is formed in the semiconductor layer to be oxidized by selectively oxidizing from a side surface of the hole. In the first DBR, a first current path is formed by a conductive region surrounded by the oxidized region, and a second current path is formed by a conductive region not surrounded by the oxidized region.

An internal combustion engine variable compression ratio system is provided that includes a piston inner (5a), a piston outer (5b) that is fitted around the outer periphery of the piston inner (5a) so that it can slide only in the axial direction and is capable of moving between a low compression ratio position (L) and a high compression ratio position (H), a raising member (14) that can pivot around axes of the piston inner and outer (5a, 5b) between a non-raised position (A) and a raised position (B), and an actuator (20) connected to the member (14) and pivoting it to the non-raised position (A) or the raised position (B), in which piston outer high compression ratio position latching means (30b) is disposed between the piston inner (5a) and the piston outer (5b) and operates, when the piston outer (5b) has reached the high compression ratio position (H), so as to prevent relative axial movement of the piston inner (5a) and the piston outer (5b). It is thereby possible to provide a variable compression ratio system that enables the piston outer to be moved to the low compression ratio position and the high compression ratio position simply and reliably without rotating the piston outer.

A VCSEL includes a substrate, a first semiconductor multilayer of a first conductivity-type, an active layer, a second semiconductor multilayer of a second conductivity-type, a contact layer, each of the layers stacked on the substrate. The second semiconductor multilayer constitutes a resonator together with the active layer and the first semiconductor multilayer. A metal layer is formed on the contact layer. The metal layer includes an opening portion that defines a region that emits laser light. When oscillation wavelength of the laser light is λ, optical thickness T of the contact layer and a top layer of the second semiconductor multilayer that contacts with the contact layer is smaller than λ/4.

A switch device is provided that includes a first switch portion in which an upper electrode and lower electrodes face each other at a predetermined gap and a second switch portion having metal domes which are disposed at a lower side facing the first switch portion and expand to a predetermined height. A first spacer having a predetermined thickness A is disposed in the first switch portion to form a gap between the upper electrode and the lower electrodes, a second spacer having a thickness B equal to or greater than the expanded height of the metal domes is disposed in the second switch portion, and the thickness of the second spacer is greater than that of the first spacer.
