Title: Television receiver
Inventor: ISHIBASHI TAKUYA
IPC: H04N5/445
Filed: 1992-09-09
Abstract: PURPOSE:To correctly detect the position of an RF signal with a simple constitution to skip this position at the time of using channel up and down keys for channel selection by constituting the television receiver so that channels, which are selected in the case that the same phase is not detected by phase comparison, are skipped at the time of channel selecting operation. CONSTITUTION:A detection signal 13 obtained by a tuner circuit 5 is allowed to pass a synchronizing signal separation circuit 4, and phases of an obtained synchronizing signal 10 and a flyback H pulse signal 11 outputted from a flyback transformer 6 are compared with each other by a signal detecting circuit 3. Signal presence is discriminated when they have the same phase, but signal absence is discriminated when phase comparison is impossible because of the absence of the synchronizing signal 10, noise, or the like; and signal presence/absence information is outputted to a microcomputer 2 as a signal presence/ absence signal 9. When the microcomputer 2 is operated by the operation of a channel up/down key 1 for channel selection, it is determined in accordance with contents of the signal presence/absence discrimination signal 9 whether the position should be displayed or skipped.

Abstract: PURPOSE:To reduce the shrinkage amount of a PE tube to be used in real circumstances for a long period of time and to obtain high reliability by the application to a pneumatically feeding and mounting optical cable by determining the molding time remaining distortion of the tube to be used to a specific value or less. CONSTITUTION:In a pipe cable in which several pipes 2 each made of a PE tube to be used for a pneumatically feeding optical cable laying system are associated and a sheath 1 is provided thereon, the molding time remaining distortion of the tube 2 to be used is set to 1% or less. Thus, when the long term use is considered in normal temperature circumstances, i.e., in a temperature range of -40 to 80 deg.C, the shrinkage amount of the tube is small. Accordingly, the retraction of the tube 2 in the vicinity of the end of the cable is reduced. Therefore, an increase in the slack generated in the tube 2 of the contained optical fiber unit, i.e., a large increase in the excessive length is suppressed, and the optical fiber having high reliability after laying is obtained.
