摘要:
In a transfer system for wafers, etc., a coupling chamber corresponding to a port is formed only when a transfer box comes in tight contact with an apparatus as a transfer target in the transfer box is transferred into the apparatus, so that the transfer target will be transferred together with the coupling chamber into the apparatus by means of magnetic attraction forces exerted between the transfer box, transfer box door and apparatus door, thereby simplifying the structures of the transfer box and apparatus and also allowing the transfer target to be transferred into the apparatus without fail.

A high reduction combined planetary gear mechanism includes an input shaft (2), an output shaft (3), a first planetary gear mechanism (4), and a second planetary gear mechanism (5). The first planetary gear mechanism (4) includes a first sun gear (6) of which the center is coupled to the input shaft (2), a first internal gear (7), and a first planetary gear (8). A first support shaft (9) for rotatably supporting the first planetary gear (8) is fixed to a first carrier (10), and the output shaft (3) is fixed to the center of the first carrier (10). The second planetary gear mechanism (5) includes a second sun gear (11) of which the center is coupled to the input shaft (2), a second internal gear (12), and a second planetary gear (13). A second support shaft (14) for rotatably supporting the second planetary gear (13) is fixed to a stationary frame. The first internal gear (7) and the second internal gear (12) are formed on the inner peripheral surface of a rotatable common annular frame (16). The annular frame (16) is rotatably mounted on the input shaft (2).
摘要:
The present invention relates to a portable telephone, and an object of the present invention is to provide a portable telephone and an additional device for the portable telephone capable of improving the portability of the portable telephone in the case that a power source of the portable telephone is additionally provided and the functionality of the portable telephone is extended. The additional device for the portable telephone main body having a connection function with a telephone line, can be detachably attached to a power source section, and has a power source terminal portion capable of being detachably attached to a power source terminal portion in the power source section. That is, the additional devices for the portable telephone having various functions can be prepared as options, and the selected additional device can be integrally attached to the portable telephone comprising the conventional portable telephone main body and the power source section to improve the portability. The additional devices for the portable telephone can have a power source function, a modem function, an extension function for extending the functionality of the portable telephone main body, or a card receiving mechanism.

A self reconfigurable cellular robotic system comprises cells having arms which can be independently extended and retracted in both directions along three orthogonal axes by actuators and coupling member at the distal ends of the arms for coupling adjacent cells. The arrangement of the cells can be modified by extending and retracting the arms and coupling and uncoupling the coupling members.

An electronic money coffer with an improved safety relative to an abnormal state such as fire. The electronic money coffer is provided with a depository unit having a structure resistant to an abnormal state. The depository unit accommodates the optional number of electronic money storing media such as IC cards excepting those electronic money storing media used in ordinary electronic money dealing. When a sensor detects an abnormal state such as abnormal temperature and smoke caused by a fire or the like, the values of electronic money in the electronic money storing media used in ordinary electronic money dealing are transferred to the electronic money storing media in the depository unit. The electronic money coffer can maintain by itself the safety of electronic money when a fire or the like occurs. The assets in an electronic money dealing system can be safely and reliably managed by the electronic money coffer which is compact and cost effective.

A process of thermally cracking a heavy petroleum oil wherein the heavy petroleum oil is treated successively in a cracking furnace and then in a perfect mixing type tank reactor. The thermal cracking in the cracking furnace is performed at a temperature at the outlet of the cracking furnace of 450.degree.-520.degree. C. with a conversion of at least 60-75% of the overall conversion rate while the thermal cracking in the tank reactor is performed at a temperature of 400.degree.-450.degree. C. a pressure of from ambient pressure to 1 kg/cm.sup.2 for a period of time of less than 30 minutes but not less than 10 minutes while feeding steam having a temperature of 435.degree.-700.degree. C. to the tank reactor in an amount of 8-20% by weight of the heavy petroleum oil fed to the cracking furnace.

摘要:
An amplitude-adjusting circuit used for a contrast-adjusting circuit of resistor division type in which a video signal is applied across a pair of series-connected resistors and an output is produced from the junction point of the two resistors. At least one of the resistors is used as a variable resistor. The amplitude-adjusting circuit comprises a current source for supplying a constant current steadily between the terminals of the variable resistor, a high-gain amplifier for controlling the resistance value of the variable resistor, and a filter for separating the video signal component from the change of the value of the variable resistor represented by a voltage change, and introducing the resistance change to the high-gain differential amplifier.
