摘要:
A method of manufacturing a hydrogen separation membrane with a carrier is characterized by including a first step of providing, between the hydrogen separation membrane and the carrier that supports the hydrogen separation membrane, a low-hardness metal membrane having a hardness that is lower than the hardness of the hydrogen separation membrane, and a second step of joining the hydrogen separation membrane, the low-hardness metal membrane, and the carrier by a cold joining method. In this case, it is possible to suppress the deformation of the hydrogen separation membrane, the low-hardness metal membrane, and the carrier and, as a result, it is possible to prevent damaging of the hydrogen separation membrane. The adhesion of the contact between the hydrogen separation membrane and the carrier is also improved. The result is that it is not necessary to increase the severity of the cold joining conditions.

An imaging area image is displayed on a monitor instead of an enlarged image after a focus state is maintained by an operation of a second operation member used for instructing maintenance of the focus state, if a first operation member configured to issue an instruction to start focus control is re-operated.

A fuel cell includes a joint portion A in which a first conductive separator, an electrolyte-strengthening substrate and a second conductive separator are jointed in order with a brazing material. The electrolyte-strengthening substrate is formed so as to be larger than a joint area of the first conductive separator and a joint area of the second conductive separator in the joint portion. The electrolyte-strengthening substrate has an insulating property at least at an area where the electrolyte-strengthening substrate contacts with the brazing material.

A method of manufacturing a hydrogen separation membrane comprises the steps of forming an intermediate layer suitable for controlling oxidation of a hydrogen permeable metal layer on the surface of the hydrogen permeable metal layer on the surface of the hydrogen permeable metal used as a substrate; and attaching a catalytic metal in a granular form on the surface of the intermediate layer. This method can be used to manufacture a hydrogen separation membrane in which the quantity of catalytic metal used is controlled.

A technology for preventing degradation of a hydrogen permeable metal layer in a fuel cell 210 is provided. A fuel cell system 200 including a fuel cell 210 with an anode which has the hydrogen permeable metal layer comprises a fuel cell controller 230 for controlling the operation status of the fuel cell system 200, a temperature parameter acquisition section for acquiring a temperature parameter of the hydrogen permeable metal layer, and a hydrogen permeable metal layer degradation prevention section which reduces the hydrogen partial pressure in an anode channel 212 for supplying fuel gas to the anode. If a temperature of the hydrogen permeable metal layer represented by the temperature parameter deviates from a specified temperature range, the fuel cell controller 230 cause the hydrogen permeable metal layer degradation prevention section to operate for preventing degradation of the hydrogen permeable metal layer.
摘要:
An image-processing device generates image data in consecutive-photographing mode and stores the image data and file-management information in a removable recording medium. Data on images photographed consecutively is stored in an internal memory of a device in sequence and written into the removable recording medium in sequence. To reduce the number of writing data into the removable recording medium while in the consecutive-photographing mode, the file-management information used for managing a file including the image data is written into the removable recording medium only when a predetermined condition is satisfied while the file-management information is stored and updated in the internal memory.

A fuel cell is made by laminating an anode channel 2 supplied with hydrogen or a hydrogen-containing gas gH, a cathode channel 3 supplied with oxygen or an oxygen-containing gas GO, and an electrolyte 4 arranged between the cathode channel and the anode channel. The electrolyte 4 is made by laminating a hydrogen separating metal layer for making hydrogen supplied to the anode channel 2 or hydrogen in a hydrogen-containing gas GH supplied to the anode channel 2 permeate; and a proton conductor layer made of ceramics, for establishing the hydrogen having permeated the hydrogen separating metal layer in a proton state and making it reach the cathode channel 3. In addition, the fuel cell has a coolant channel 5 for cooling the fuel cell 1. In the coolant channel 5, a low heat conducting section 55 having a heat conductivity smaller than that at a downstream side of a coolant C is formed at an inlet side of the coolant C.

摘要:
A dry-etching method comprises the step of dry-etching a metal thin film as a chromium-containing half-tone phase-shift film, wherein the method is characterized by using, as an etching gas, a mixed gas including (a) a reactive ion etching gas, which contains an oxygen-containing gas and a halogen-containing gas, and (b) a reducing gas added to the gas component (a), in the process for dry-etching the metal thin film. The dry-etching method permits the production of a half-tone phase-shift photomask by forming patterns to be transferred to a wafer on a photomask blank for a chromium-containing half-tone phase-shift mask. The photomask can in turn be used for manufacturing semiconductor circuits. The method permits the decrease of the dimensional difference due to the coexistence of coarse and dense patterns in a plane and the production of a high precision pattern-etched product.
