Title: Shaft seal device
Inventor: ADACHI TORU
IPC: F16J15/3252
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To prevent the loosening deformation of a lip due to a bubbling phenomenon and further prevent a leakage by keeping the lip in contact with the internal surface of an outer case via a coolant releasing space forming tool, applying a coolant releasing structure, and forming a coolant releasing passage on a contact area between the lip and the internal surface of the outer case. SOLUTION: A shaft seal device 9 has a metal L-type circular washer 8a as a coolant releasing space forming tool inserted in space between a lip 6 and the internal surface of an outer case 7. As a result, the roughness of contact surface between the washer 8a and the case 7 becomes large, and the contact surface can work as a coolant releasing passage, upon the generation of a bubbling phenomenon. Also, when the coolant releasing space forming tool is made of a resin L-type roughened washer 8b, the roughness of contact surface between the washer 8b and the case 7 becomes large. Thus, the contact surface acts as a coolant releasing passage, upon the generation of a bubbling phenomenon.  According to this construction, excessive pressure existing between the lip 6 and the case 7 is momentarily released and reduced, thereby preventing the occurrence of a lip loosening deformation due to a bubbling phenomenon.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a line in terms of an operation cost by conducting connection/interruption of a public line being a bypass in a proper timing so as to reduce the line operation cost. SOLUTION: The attribute of plural housed channels is classified into 1st attribute or the like not permitting a connection delay of a public line 4, and connection priority of channels of channels with the 1st attribute among unconnected channels is decided depending on the order of higher transmission speed and a past operating rate before calls overflow from a private channel 3.

Abstract: PURPOSE:To reduce the radar cross sectional area of an antenna by driving a phased array antenna only in a mechanically narrow angular range in accordance with the angular direction of a target to be tracked and offsetting an antenna surface and a radio wave axis. CONSTITUTION:A phased array antenna 11, driving circuit 12, transmitter/receiver 13, signal processor 14, and a display device 15 are connected. A transmission signal from the transmitter/receiver 13 is sent to the antenna 11 and radiated from the antenna 1' 1 in a prescribed angular direction. The echo signal reflected by a target is received by the antenna 11, received and amplified by the transmitter/receiver 13 and then sent to the processor 14. The received signal is detected by the processor 14 and displayed on the display device 15 as a target information. When the target is detected, the radar is turned to a tracking mode, and the processor 14 sends a directional angle data to the antenna 11 so that an antenna beam is always directed to the target direction on the basis of an angular error signal obtained from the antenna 11. On the other hand, the processor 14 sends mechanical driving angle data to the circuit 12 to control the antenna 11 so that the front direction of the antenna 11 and the radio wave axis are offset each other to control to recue the radar cross sectional area.
