摘要:
A heat resistant alloy comprising, in % by weight, over 0.6% to not more than 0.9% of C, up to 2.5% of Si, up to 3.0% of Mn, 20 to 28% of Cr, 8 to 55% of Ni, 0.01 to 0.8% of Ti and 0.05 to 1.5% of Nb, the balance being Fe and inevitable impurities, the value of (Ti+Nb)/C being 0.12 to 0.29 in atomic % ratio. When the alloy further contains up to 0.5% of Zr, the value of (Ti+Nb+Zr)/C is 0.12 to 0.29 in atomic % ratio. When the alloy is heated at a temperature of at least about 800 degrees C., a fine Ti—Nb—Cr carbide or Ti—Nb—Zr—Cr carbide precipitates within grains to thereby retard creep deformation and give an improved creep rupture strength. The alloy is therefore suitable as a material for hydrogen production reforming tubes.

摘要:
A steam valve is provided with a valve body, a valve seat, and a valve rod provided for the valve body. The valve body has a bottom portion to which a recessed portion is formed, and the recessed portion has an edge, which is positioned on an upstream side of a place at which a shock wave is generated in steam flowing through a steam path defined by the valve body and the valve seat.
摘要:
An elevator entrance apparatus includes a reading device for reading transmission information from a transmission device, and a control device for controlling operation of an elevator based on information as to whether transmission information has been read by the reading device or not. The reading device reads transmission information only when the transmission device is within a predetermined detection range on an inner side of an elevator entrance.

A vehicle-mounted man-machine interface device comprises display means for displaying a screen, press position detecting means for detecting the press position on the screen, and control means for displaying an operating screen on which operating figures are arranged on the display means and acquiring the operation content specified by the press on the operating screen from the arrangement positions of the operating figures, the operation on each operating figure, and the output of the press position detecting means. The device further comprises traveling detecting means for detecting whether or not the vehicle having the device is traveling or detecting the traveling speed of the vehicle. The control manes sets or alters one or both of the number of operating figures simultaneously displayed on the operating screen and their sizes according to the output from the traveling detecting means. With this, a man-machine interface technique for easily and reliably performing operation can be provided.
摘要:
A copolymer expressed by the following structural formula was obtained by loading adamantyl methacrylate monomer and t-butyl acrylate monomer by 1:1, then conducting polymerization, adding AIBN as a polymerization initiator, and then conducting precipitation purification with methanol. Then to the copolymer, triphenylsulfonium hexafluoroantimonate was added to prepare a cyclohexanone solution. This solution was applied to a wafer, and exposed to a KrF excimer stepper and developed. The threshold energy Eth was 50 mJ/cm2. A 0.45 μm-wide L & S was formed at 130 mJ/cm2. The radiation sensitive material has good transparency and etching resistance, high sensitivity, and little peeling.

A cutting apparatus for a ceramic green sheet according to the present invention is a cutting apparatus for a ceramic green sheet for cutting a ceramic green sheet held on a carrier film into a square-shaped sheet piece, and comprises four roller cutters, each of which is disposed so as to correspond to each edge of the sheet piece, and moving means for moving the roller cutters along the corresponding edges of the sheet piece. In this cutting apparatus, the four edges of the sheet piece are cut by the roller cutters, thus cutting failures on the ceramic green sheet are significantly prevented. Furthermore, each of the edges of the sheet piece is cut without changing the position of the cutters, thus improvement of cutting dimensional accuracy is realized, compared to the conventional apparatus in which the position of the cutter is changed when cutting each edge.
摘要:
The present invention provides an optical module using optical waveguides which permits easy fabrication of a PLC type optical multiplexer/demultiplexer with reduced loss. The optical module comprises cores which are contiguous to each other through a dicing groove adapted to position and fix an optical functional part such as a wavelength selection filter and a core branched from the said cores. A slight gap is present between the former and the latter core and both cores are narrower in width in the vicinity of the dicing groove than the other portions.
