摘要:
The present invention discloses an image-forming optical system provided with a plurality of curved mirrors whereby two points at different distances are made to have an optically conjugate relationship, sequentially starting with a first conjugate point which is nearer when an optical path is traced from the first conjugate point to a second conjugate point which is farther, comprises, a first mirror which reflects luminous flux from the first conjugate point to transform the luminous flux into substantially parallel luminous flux, and a second mirror which reflects the luminous flux reflected by the first mirror while keeping the luminous flux substantially parallel. Further, the optical system satisfies the following condition: |Arctan(1/2F)−|2×(ξ−η)||≦10[deg]

A discharge lamp includes a luminous bulb in which a luminous material is enclosed and a pair of electrodes are opposed in the luminous bulb; and a pair of sealing portions for sealing a pair of metal foils electrically connected to the pair of electrodes, respectively. At least one of the pair of metal foils has a twist structure.

A gas dissolved water producing apparatus includes a gas dissolving section, a gas channel for guiding a gas into the dissolving section, a first water channel for guiding water into the dissolving section, a gas dissolved water discharge channel, and a second water channel for guiding the water without passing through the dissolving section. The second water channel joins the gas dissolved water discharge channel to control the solution gas dissolved in the gas dissolved water can be controlled to a prescribed level of concentration.

A plurality of user terminals regularly accessing Internet Relay Chat (IRC) services are also in communication with a service selecting host. The service selecting host is configured to collect data from the plurality of user terminals. The collected data includes information about the users at the user terminals and information about the user terminals activity in the accessing of the IRC services. The service selecting host compiles and sorts the collected data concerning IRC services to produce information provided to the user terminals. The information provided to the user terminals allows users at the user terminals to more easily select sorted IRC services.

A short arc mercury lamp includes a luminous bulb enclosing at least mercury as a luminous material and a pair of electrodes opposed to each other; and a pair of sealing portions for sealing a pair of metal foils electrically connected to the pair of electrodes, respectively. The electrode central axis of one of the pair of electrodes is dislocated from the electrode central axis of the other electrode. The shortest distance d (cm) between the head of one of the electrodes and the head of the other electrode is larger than the value of (6M/13.6&pgr;)1/3 when the total mass of the enclosed mercury is M (g).

To notify users, in real time, of information that matches a search preference. Preference database 12, register 11, preference setting unit 1, recording unit 13, preferential search unit 14, notification unit 15 and channel display section 2 are provided. Preference database 12 stores, associated with the user, one or more search preferences to search for a channel. Register 11 registers search preferences in preference database 12. Preference setting unit 1 receives the input of search preferences, and sends them to register 11, associated with the user. Recording unit 13 stores the state of each channel. Preferential search unit 14 judges, based on the state of each channel, whether each channel satisfies any search preference. Based on the judgment of preferential search unit 14, notification unit 15 notifies the corresponding user terminal of the channel that meets any search preference of the user. Channel display section 2 outputs the reported contents.
摘要:
In the case where specification of service to be used is received, the specified service is retrieved from a service table, in which services and script files storing a scripts combined in the services are stored with them corresponding with each other, a script file is specified, and use of the specified script file is executed so that use of the service is executed. The use of the script file is specifically transmission, addition or deletion of the script file.
摘要:
A DC plasma jet CVD process having a high film deposition rate is employed. A material having low adhesion with diamond is used for a substrate. A diamond film automatically peels from the substrate at the time of cooling. Gas is recycled because gas utilization efficiency is low. In this case, deposition of carbon can be prevented by setting a gas flow velocity to at least 5 m/s in the proximity of an anodic point.

A multi-tube heat exchanger includes a pair of tanks and a plurality of heat transfer tubes fluidly interconnected between the tanks. The heat transfer tubes are arranged so that at least one of tube-arrangement surfaces formed on entrance and exit sides of the heat exchanger in a passage direction of air subjected to heat exchange is formed as two or more surfaces different from each other, and air flow is separated or joined in the multi-tube heat exchanger. An air conditioner according to the present invention has such a multi-tube heat exchanger in an air path. The multi-tube heat exchanger can be made smaller while a desired heat exchange property can be maintained. An air conditioner having such a heat exchanger also can be made smaller.
摘要:
A process and apparatus for producing a diamond film from a gas phase, in which a fuel gas is burnt by oxygen gas in a torch, to thereby provide a gas flame jet having a high temperature and high speed sufficient to form a high quality diamond film on a substrate, by an unlimited use of various kinds of combustible carbon compound gases as the fuel gas. A process and apparatus for producing a diamond film from a gas phase, in which a thermal spray material is fed to a combustion flame to thereby form an intermediate layer of a mixture of the thermal spray material and diamond between a substrate and a diamond film, to thereby provide a high purity diamond film having an improved adhesion to the substrate.
