摘要:
A furnace for the formation of a black oxide film on the surface of a thin metal sheet is disclosed which comprises a tunnel-like furnace proper provided at one terminal side thereof with an inlet and at the other terminal side thereof with an outlet, conveying means laid inside the furnace proper from the inlet through the outlet thereof for conveying a thin metal sheet from the inlet to the outlet, openable shutter means for partitioning the interior of the furnace proper into at least first and second regions on the front and rear sides respectively in the direction of conveyance of the thin metal sheet, first gas supply means for feeding into the first region on the inlet side of the furnace proper partitioned by the shutter means a mixed gas containing carbon dioxide and carbon monoxide and containing substantially no oxygen or a mixed gas containing carbon dioxide, carbon monoxide, and steam and containing substantially no oxygen, second gas supply means for feeding into the second region on the outlet side of the furnace proper partitioned by the shutter means a mixed gas containing carbon dioxide, carbon monoxide, and oxygen and containing substantially no steam, and heating means for heating the first region to a temperature in the range of 500.degree. to 650.degree. C. and the second region to a temperature in the range of 100.degree. to 300.degree. C.

摘要:
A communication quality evaluation system, a device, a method, and a program for evaluating communication quality at an arbitrary location, in the form which can actually felt by a user, are provided. According to an instruction from an evaluator, a control device displays a map or layout diagram of a specified area on a map/layout diagram display device and specifies an evaluation point within a display range of the map or the layout diagram. According to the network quality estimated by a network quality estimation unit, a network quality simulation unit for estimating the network quality when communications are performed at the evaluation point deteriorates the evaluation data and transmits the data to an evaluation device. The evaluation data deteriorated is a sample of data actually transmitted and received in the communication system. The evaluation device uses a communication device actually used by a user in the communication system.

In an aperture stop mechanism, two aperture blades are arranged so as to overlap each other and form a single light passage opening into which light utilized in imaging is introduced with the respective edge portions of the two aperture blades. A drive mechanism drives the two aperture blades in directions different from each other, whereby the aperture area of the light passage opening is changed within a predetermined range. When the two aperture blades are located at a minimum aperture position where the aperture area of the light passage opening is minimum within the predetermined range, the two aperture blades are provided so that the single light passage opening surrounded by boundaries including eight straight lines is constituted of the respective edge portions of the two aperture blades.
摘要:
A reformer including a vaporization part provided with a supply port through which raw fuel is supplied, the supply port being provided at a central section of a tubular container; and reforming parts provided at both sides of the container, each reforming part containing reforming catalyst that reforms the raw fuel that flows into the reforming part from the vaporization part into fuel gas and provided with a fuel-gas supply port through which the fuel gas is discharged.

In an insertion hole formed in an adapter, a side wall which presses an insertion piece of a stopper with an urging force of a spiral spring has a wall surface parallel to a virtual straight line passing a center of the adapter and positioned on the virtual straight line. Thus, a direction which the wall surface of the side wall presses the insertion piece of the stopper is along a facing direction which the side wall and another side wall face each other, and is not inclined outward in a radial direction of the adapter with respect to the facing direction. Thereby, a pressing force applied from the wall surface of the side wall to the insertion piece of the stopper does not cause the insertion piece to be extruded from the insertion hole. Thus, insertion state of the insertion piece to the insertion hole can be satisfactorily maintained.

A fuel cell module includes in a casing: a fuel cell stack that is formed by stacking a plurality of unit cell; an oxidant gas distributing member that is disposed at a side surface, that extends in a stack direction of the unit cells, of the fuel cell stack that extends in a direction from one end to another end of each of the unit cells, and that supplies the oxidant gas to the another end of each unit cell after supplying the oxidant gas through the oxidant gas distributing member from the one end to the another end; a reformer disposed at the one end; and a combustion portion that is disposed between the one end and the reformer. The oxidant gas distributing member has a higher thermal conductivity at the one end side of the unit cells than at the another end side of the unit cells.

A seat back locking device for an automobile for a seat back 5 configured so as to be capable of being changed from an upright position to a folded-down position and vice versa, including a locking mechanism 10 for locking the seat back 5 in the upright position, a locking knob 20 for unlocking the locking mechanism 10, and a key cylinder 30 capable of locking and unlocking the locking knob 20. In the locking device, a contact part 33 that comes into contact with a contacted part 26 provided on the locking knob 20 is connectingly provided integrally with a cylinder body 31 of the key cylinder 30 so that the key cylinder 30 can be changed over between a locked state in which the contact part 33 comes into contact with the contacted part 26 to inhibit the rotation of the locking knob 20 and an unlocked state in which the contact part 33 does not come into contact with the contacted part 26 to allow the rotation of the locking knob 20.
摘要:
A printing system that adopts an SBC system in which a load at a server is alleviated when executing printing to enable printing to be performed smoothly. In the printing system, a client terminal, a server, and an image forming apparatus are connected to each other through a network. The client terminal specifies data among stored data in the server and sends a print execution request to the server. The server receives the print execution request, creates print-related information relating to the specified data, and sends it to the client terminal. The client terminal judges whether or not print data generation processing with respect to the specified data is possible at the client terminal based on the print-related information, and send the judgment result to the server. The server allocates the print data generation processing to either the server or the client terminal based on the judgment result.
