摘要:
A method for forming a thin film of a metal compound is disclosed. Within a vacuum chamber, a metallic ultra-thin film of a metal or an incompletely-reacted metal is deposited on a substrate. The metallic ultra-thin film is brought in contact with the electrically neutral activated species of a reactive gas so as to convert the metallic ultra-thin film to an ultra-thin film of a metal compound through the reaction of the metallic ultra-thin film with the activated species of the reactive gas. The above-described steps are sequentially repeated so as to deposit on the substrate the ultra-thin film of the metal compound in layers until a thin film of the metal compound having a desired thickness is formed on the substrate.

There is disclosed a method and apparatus for forming a thin film of a composite metal compound. Independent targets formed of at least two different metals are sputtered so as to form on a substrate an ultra-thin film of a composite metal or an incompletely-reacted composite metal. The ultra-thin film is irradiated with the electrically neutral, activated species of a reactive gas so as to convert the composite metal or the incompletely-reacted composite metal to a composite metal compound through the reaction of the ultra-thin film with the activated species of the reactive gas. The formation of the ultra-thin film and the conversion to the composite metal compound are sequentially repeated so as to form on the substrate a thin film of the composite metal compound having a desired thickness.

An interface circuit for connecting a tablet to an analog input unit of a computer, comprises a sawtooth generator operable in synchronism with a preset timing of the computer for generating a sawtooth voltage, and a comparator for comparing the sawtooth voltage with an output voltage from the tablet. The output voltage from the tablet can be converted into an output voltage having a corresponding time duration, which is supplied to the analog input unit.

An image forming apparatus includes a photosensitive belt carried by a driver device, for forming a toner image thereon; an internal transcription belt for transcribing the toner image; and a transcription portion for transcribing the toner image, which is transcribed on the internal transcription belt, onto a recording medium. A transcription side roller is suspended with the internal transcription belt thereon, and disposed on a side of a photosensitive belt side roller. Detectors detect a first cycle of the internal transcription belt, and a second cycle, which starts measurement delaying by ½ cycle of the photosensitive belt side roller from the first cycle measurement start. A controller conducts speed compensation of the photosensitive belt by referring to the first cycle and the second cycle, wherein the internal transcription belt is in contact with the photosensitive belt, so that it is carried following thereafter.

One embodiment of the present invention provides a method of fabricating a cathode requiring relatively few and somewhat simple steps. One embodiment also provides a method of fabricating a cathode which eliminates a direct via masking step. One embodiment provides a method of fabricating a cathode which reduces manufacturing costs and increases the efficiency and productivity of manufacturing lines engaged in cathode fabrication. One embodiment provides a method of fabricating a cathode, which reduces the unit cost of thin CRTs. In one embodiment, a novel method effectuates fabrication of a cathode by a process requiring relatively few and somewhat simpler steps. Importantly, in the present embodiment, the requirement for at least one conventionally required direct via masking steps is eliminated. This effectively eliminates or substantially reduces associated costs, concomitantly reducing process completion time. Advantageously, this increases efficiency and productivity, correspondingly reducing fabrication costs and unit costs of finished devices.

A shell-and-tube apparatus, more specifically, a shell-and-tube reactor, which includes a vessel, at least one intermediate tube plate sectioning the interior of the vessel into at least two compartments having different temperatures, a number of heat transferring tubes penetrating the intermediate tube plate or plates, and a fluid passing through the tubes which is heated or cooled by a heat transfer medium surrounding the tubes. At least one insulation plate or plates are provided on one or both sides of the intermediate tube plate so that the space between the intermediate tube plate or plates and, if two or more insulation plates are used, the space or spaces between the insulation plates may be utilized as a stagnation zone for the heat transfer medium, so as to make the temperature gradient through the intermediate tube plate or plates gentle and relax the thermal stress occurring in the body wall. The reactor is particularly useful for production of (meth)acrolain and/or (meth)acrylic acid by catalytic gas-phase oxidation of propylene or butenes.
摘要:
A sub-frame supporting device in which a sub-frame adapted to support an engine, wheels and the like is supported from the body of a vehicle through an elastic support member. The supporting device comprises a pair of upper and lower holding plates oppositely disposed, a spacer pipe connecting the holding plates, a fastener for fastening the holding plates to a vehicle body and an elastic support member. A flange of the sub-frame is held between the elastic support member and a damper rib, and gaps are formed adjacent the upper and lower surfaces of the elastic support member. The rigidity of the elastic support member is set so as to be decreased with respect to vertical shearing force and increased with respect to lateral compressive force.

Disclosed is a variable venturi type carburetor comprising a movable suction piston. The suction piston has a needle entering into a stationary jet. The needle and the jet defines an annular opening through which the fuel is injected into the intake passage formed in the carburetor. The jet is connected to a fuel reservoir via a fuel supply passage. The fuel reservoir is connected to the intake passage located downstream of the needle.

A breathable seat comprises a seat body formed of urethane foam, a three-dimensional network cushion body incorporated in that region of the seat body which bears a user's body, a seat cover having breathability, and a pan frame. The cushion body is formed of a large number of continuous linear elements of thermoplastic resin. The linear elements are looped windingly so that their respective contact portions are fused together. The seat body is formed having venting holes that penetrate the urethane foam in its thickness direction. The venting holes communicate with the cushion body and apertures of the pan frame. The seat cover envelops the seat body and the cushion body.
