IPC: H04N7/16
Filed: 1988-05-25
Abstract: PURPOSE:To increase controllable terminals in a simple constitution by setting a frequency converting device on a trunk line, connecting two data controllers to the said trunk line in a center, and executing polling with respective different frequencies. CONSTITUTION:The frequencies of a terminal control signal sent from a first controller 1 of a CATV center are modulated to carrier frequencies (f1), those sent from a second data controller 4 are modulated to carrier frequencies (f2), and they are sent to a mixer 3. For the video of a CATV, the video signal form a video source 6 is sent to the mixer 3. Further, it is sent from the mixer 3 to a network 3. The waves at the frequencies (f1) and (f2) arrive at subscriber terminals 11-13, on the contrary, since the terminals 11-13 demodulates only the frequencies (f1), the signals are controlled by the device 1. A frequency converting device 9 interrupts the signal at the frequencies (f1), and converts the signal at the frequencies f2 into the one at the frequencies (f1). Consequently, since subscriber terminals 21-23 demodulates the signal at the frequencies (f1), the signals are controlled by the device 4.

Title: Part with o-ring groove
Inventor: KURODA KENICHI
IPC: F16J15/10
Filed: 1982-07-22
Abstract: PURPOSE:To prevent coming-out of an O-ring and to facilitate operation for fitting the O-ring in place, by forming a pocket at least at one side of the side wall of an O-ring groove so that when the deformation of the O-ring is caused, the deformed part of the O-ring is accommodated in the pocket. CONSTITUTION:A ring-shaped pocket 15 is formed on the inside of an O-ring groove 11. In fitting an O-ring 16 into the O-ring groove 11, part of the O-ring 16 is at first fitted into a part of the O-ring groove 11, and then the O-ring 16 is fitted into the groove 11 little by little by pushing the same along the circumferential direction. In the state that the O-ring 16 is fitted completely into the O-ring groove 11, the O-ring 16 causes deformation i.e., shrinkage in the O-ring groove 11 by its restoring force, so that the deformed part of the O-ring 16 is accommodated in the pocket 15. Thus, since the deformation of the O-ring 16 serves to prevent coming-out of the O-ring 16 from the groove 11, the O-ring 16 is retained in the groove 11 in a proper state.
