Abstract: The solid-state imaging element includes a photoelectric converter, a first separator, and a second separator. The photoelectric converter is configured to perform photoelectric conversion of incident light. The first separator configured to separate the photoelectric converter is formed in a first trench formed from a first surface side. The second separator configured to separate the photoelectric converter is formed in a second trench formed from a second surface side facing a first surface. The present technology is applicable to an individual imaging element mounted on, e.g., a camera and configured to acquire an image of an object.

Abstract: Provided are: a fouling inhibitor that is capable of effectively inhibiting fouling of porous filtration membranes use as water purification membranes or the like, that has resistance to chemicals, such as alkali used when the membrane is fouled, and that is capable of maintaining such effects sufficiently even after chemical wash; a filtration membrane provided with the inhibitor; and a method for producing the same. The inhibitor contains: (A) a copolymer having a weight average molecular weight of 10000 to 300000 and contains a MPC unit (a1) and a BMA unit (a2), wherein the ratio of (a1) to (a2) ((a1)/(a2)) by mole is 10/90 to 70/30; and (B) PVA having a saponification degree of 72 to 93 mol % and a polymerization degree of 300 to 1000, wherein the ratio of component (A) to component (B) ((A)/(B)) by mass is 25/75 to 75/25.

Abstract: A steam turbine having a fork-type joint structure is provided that secures sufficient strength for endurance of stress corrosion cracking, low-cycle fatigue, and high-cycle fatigue, and extends an operating life while making it possible to endure long-term operation. The turbine includes a rotor having a plurality of rotor forks rowed in an axial direction; a turbine blade having blade forks arranged in the axial direction of the rotor, the blade forks engaged with the rotor forks; a plurality of pin holes whose positions are different from each other in the radial direction of the rotor; and a plurality of fork pins inserted into the plurality of pin holes in the axial direction of the rotor. A clearance exists between an inner diameter of the pin hole of the blade fork and a diameter of the fork pin, the clearance varying depending on positions in the axial direction of the turbine.

Abstract: There is provided a microdevice which supplies two or more kinds of fluids flowed into itself independently toward a joining region respectively, and which discharges those fluids from the joining region. The microdevice is constituted by a supply channel which supplies each fluid flowed into the microdevice toward the joining region and a discharge channel which discharges the joined fluid from the joining region toward outside of the microdevice, in a manner that a supply channel which supplies at least one kind of the fluid has a plurality of subchannels which supply the fluid supplied into the microdevice toward the joining region, and those subchannels and supply channels are formed so that at least one central axis of the plurality of subchannels and at least one central axis of the supply channel which supplies at least one kind of fluid other than the kind that the subchannel supplies or of the subchannel intersect at one point.

Abstract: The present invention provides an organic acid metal salt obtained by reacting a saturated monocarboxylic acid or its salt and an inorganic magnesium compound. The saturated monocarboxylic acid or its salt contains at least 97 wt % of a saturated monocarboxylic acid having 4 to 10 carbon atoms or its salt, and the organic acid metal salt contains at least 99 wt % of an organic acid magnesium salt. This organic acid metal salt consists essentially of an organic acid magnesium salt, and has excellent solubility in an alcohol solvent or a mixed solvent containing at least 5 wt % of an alcohol solvent and excellent temporal stability when being formed into a coating liquid for forming a magnesium oxide film. A coating film obtained from this coating liquid has excellent uniformity and provides a highly transparent magnesium oxide film having a thickness suitable for practical use by baking.
