The present invention provides a carbon nanomaterial production apparatus 1 that includes a reaction tube 2 into which raw material gas and carrier gas are supplied and accordingly in which carbon nanomaterial is grown, a connection tube 4 that is connected to the reaction tube 2 and through which an aerosol-like mixture of the carbon nanomaterial and the carrier gas passes, and a collection tube 3 that is connected to the connection tube 4 and collects the carbon nanomaterial from the mixture. The collection tube 3 includes a discharge section 32 that is located above a junction 33 with the connection tube 4 and discharges the carrier gas contained in the mixture to outside, and a trapping section 31 that is located below the junction 33 with the connection tube 4 and traps the carbon nanomaterial that is separated from the mixture by gravitational sedimentation.

Comprising an outside case, an inside case installed rotatably in the outside case, a cable installed in a space formed by the outside case and the inside case, and a guide ring, the guide ring is accommodated in the space so as to abut against elastically. With the frictional resistance between the guide ring and inside case being greater than the frictional resistance of the guide ring and outside case, the guide ring rotates and moves. In this constitution, generation of noise is extremely reduced. Hence, an inexpensive and highly reliable rotary connector is obtained. In particular, this rotary connector is used in a steering device of automobile or the like.

A vehicle switch has a case, a movable body, a spring, a magnet, a detector, and an operating shaft. The movable body is reciprocably accommodated in the case. The spring pushes the movable body in a direction away from an internal bottom of the case. The magnet is attached to the movable body. The detector detects a magnetic flux density generated from the magnet. A lower end of the operating shaft is in contact with the movable body. The movable body has a press contact portion with which the operating shaft is in contact at a point or along a line.

Coin processing apparatus electromagnetically tests an inserted coin, separates genuine coins from counterfeit coins by a first pathway switching mechanism, and stores genuine coins in change tubes and a cash-box by a second pathway switching mechanism, according to the type of coin. The pathway along which the coins pass is provided with pass sensors at two positions therein, where one pass sensor detects the coins and the other pass sensor controls the operation of the second pathway switching mechanism in such as manner as to prevent passing coins from becoming trapped therein. The second pathway switching mechanism is operated after a predetermined time has elapsed from the fall of a detection signal from a pass sensor, to end the flow of current through and thereby prevent overheating of a solenoid therein.

A piezo-resonator comprises a supporting frame having a recess for attaching a piezoelectric resonator element. This recess consists of three portions, that is, a central portion, a pair of connecting portions which are outside of the central portion and a pair of end portions which are outside of the pair of connecting portions. The width W.sub.2 of the connecting portion, the width W.sub.1 of the central portion and the width W.sub.3 of the end portion have the relationship W.sub.2 >W.sub.1 >W.sub.3. Two terminals intersect respective connecting portions to be embedded in the supporting frame.

Data produced from a transmission source facsimile are received by a simulated communication circuit network, and thus received data are compressed and temporarily stored into a memory. After the data have been compressed, the data stored in the memory are read out and transmitted to an other party's facsimile via an external communication circuit network. Since the data transmitted to the other party's facsimile via the external communication circuit network are compressed data, a time required for transmission can be relatively shortened. Accordingly, a rapid data transmission can be achieved without the facsimile being replaced by a rapid type facsimile which is expensive. Further, various additional functions of a facsimile can be directly enjoyed from those intrinsically owned by the transmission source facsimile. In addition, such arrangements may be made that a time presumably required for communication via the simulated communication circuit network is measured as a presumed time of communication in the normal transmission mode, while an actual time of communication in which a rapid transmission has been done by means of highly compressed data is measured, and that both the presumed communication time and the actual communication time are notified to the user so that the user can realize having saved the communication cost by means of the transmission involving data compression.

摘要:
The method for producing carbon nanotubes employs a carbon source that contains carbon and is decomposed when heated and a catalyst on a support that serves as a catalyst for production of carbon nanotubes from the carbon source. The method includes a catalyst loading step in which the catalyst starting material is distributed over the support to load the catalyst onto the support, a synthesis step in which the carbon nanotubes are synthesized on the support, and a separating step in which a separating gas stream is distributed over the support to separate the carbon nanotubes from the support, wherein the catalyst loading step, the synthesis step and the separating step are carried out while keeping the support in a heated state and switching supply of the catalyst starting material, the carbon source and the separating gas stream.
