摘要:
The present invention provides a double row taper-roller bearing and a method of assembling a double row taper-roller bearing, which are, when in an assembly, capable of assembling and being assembled by controlling a negative axial gap after the assembly. The present invention-provides also a wheel support structure and a method of the assembling the same structure.

摘要:
A coil-shaped flexible printed circuit board retains its original outer diameter unchanged without any guide or retainer. For this purpose, either the conductive pattern of copper or synthetic base material is processed to have a permanent stretch before or when the board is wound into a coil shape. A squeezing step may be employed to generate the permanent stretch on the conductive pattern. Alternatively, a heat treatment of the base material may be used to form an additional bridged ingredient after the board has been wound. The additional bridged ingredient may retain the coil shape unchanged for a long time without guiding pieces.

A copper foil for a printed wiring board which has a carbon-containing copper-zinc coating comprising 40 to 90 atomic % of copper, 5 to 50 atomic % of zinc and 0.1 to 20 atomic % of carbon is produced by dipping a copper foil in a non-cyanide copper-zinc electroplating bath containing a copper salt, a zinc salt, a hydroxycarboxylic acid or a salt thereof, an aliphatic dicarboxylic acid or a salt thereof and a thiocyanic acid or a salt thereof, and carrying out electrolysis in the non-cyanide copper-zinc electroplating bath using the copper foil as a cathode to form on at least one surface of the copper foil a carbon-containing copper-zinc coating.
摘要:
A spray drying chamber with a head section and a heat-resistant porous membrane, the porous membrane being detachable and the head section being displaceable vertically, whereby microdrops are sprayed into a spray drying chamber together with hot air, and whereby the microdrops are dried momentarily and a fine powder is produced.
摘要:
A cathode ray tube apparatus having a glass panel in front of the phosphor screen made of a material which has an X-ray absorption coefficient larger than that of the backing on which the phosphor layer is applied. The two panels are separated by means of a spacer and a liquid coolant is incorporated into the space between the panels to enhance the heat radiation effect of the phosphor surface and to avoid the radiation of X-rays.

A display apparatus includes a video signal input terminal supplied with a first video signal to be displayed; a plurality of video signal amplifiers, each producing an output signal as a primary color signal; a sync signal generating means for generating a sync signal corresponding to the first video signal; a signal generating circuit for generating a second video signal having a predetermined constant amplitude during the horizontal period; a first circuit for supplying the first video signal to at least one of the video signal amplifiers; and a second circuit for supplying the second video signal to at least one different video signal amplifier.
摘要:
A method of producing a photoelectric conversion element, which contains an electrically conductive support, a photosensitive layer having porous semiconductor fine particles that have adsorbed a dye formed on the support, a charge transfer layer; and a counter electrode; containing the steps of: applying a dispersion liquid, in which the content of solids excluding semiconductor fine particles is 1% by mass or less based on the total amount of the dispersion liquid, on the support, to form a coating; heating the coating, to obtain porous semiconductor fine particles; and sensitizing the porous semiconductor fine particles by a dye having a structure represented by Formula (1): M(LL1)m1(LL2)m2(X)m3·CI Formula (1) wherein M represents a metal atom, LL1, LL2, and X each are a ligand, CI represents a counter ion, m1 represents an integer of 1 to 3, m2 and m3 each represent an integer of 0 to 2.
摘要:
A node apparatus for forming a wireless ad-hoc network, including: a recognition possibility determination unit that determines whether or not a gateway apparatus connecting the wireless ad-hoc network to other network can be recognized; an adjoining node detection unit that detects other node apparatus which is the source of a received packet as an adjoining node; a channel switching unit that switches, when the recognition possibility determination unit determines that the gateway apparatus cannot be recognized, the channel used for reception of packets transmitted in the wireless ad-hoc network successively to each of a plurality of channels; and a channel selection unit that selects a channel to be used for communication in the wireless ad-hoc network based on the number of adjoining nodes detected by the adjoining node detection unit in each of the plurality of channels.
