Patent number: 4796032Abstract: In the storing mode, an operator section is operated to direct a parabolic antenna toward a broadcasting satellite and to select a desired channel. After the desired channel is seized, a predetermined label is input from a label input part. The satellite position and the selected channel are stored in a memory with the label attached thereto. When a search operation is performed, the direction of the antenna is gradually adjusted. Whenever the direction of the antenna is adjusted, the receiving frequency is scanned to receive each channel. When a signal is received by the frequency scanning, the type of the satellite is recognized depending on the odd or even group of channels and on whether the antenna is set to horizontally or vertically polarized wave reception. The type of the satellite as recognized, the antenna direction at that time, and the desired receiving channel transmitted from the satellite are stored into memory with a given label attached thereto.Type: GrantFiled: March 25, 1986Date of Patent: January 3, 1989Assignee: Kabushiki Kaisha ToshibaInventors: Masaru Sakurai, Hiroshi Matsue, Kazuhiro Aoki

Patent number: 4560087Abstract: The disclosure concerns a label peeling device for use with a label issuing machine, such as a hand labeler or a measuring printer. There is a feed unit for feeding a label web, which web comprises a plurality of labels temporarily adhered in series to a web of backing paper. A peeling unit turns and deflects the backing paper web rearwardly, as it is being fed by the feed unit, and the labels peel one by one from the backing paper at the line of deflection due to the rigidity of the labels. An auxiliary label peeling member is arranged in the vicinity of that portion of the peeling unit at which the backing paper and the labels separate. In some embodiments, the auxiliary peeling member has a label abutment portion so placed, shaped and sized that any label which might fail to peel from the backing paper merely by the reverse turning of the backing paper web is moved to abut the label abutment portion until it is forcibly peeled from the backing paper.Type: GrantFiled: December 23, 1982Date of Patent: December 24, 1985Assignee: Kabushiki Kaisha SatoInventors: Yo Sato, Tadao Kashiwaba, Masaru Sakurai, Yasuhiko Matsuda, Koichi Kondo

Patent number: 4389623Abstract: An automatic equalizer comprises a transversal filter connected to receive an input signal such as a television signal in which a predetermined periodic reference signal is present and having variable tap gains, and a correlator for forming the correlation between the input and output signals of the transversal filter and correcting the tap gains of the transversal filter to cancel out distortion components such as ghost component contained in the input signal. For the purpose of preventing the slow convergence and fluctuation of tap gains of the transversal filter due to non-periodic noise components contained in the input signal, a circuit is further provided to integrate a predetermined portion of the waveform of the reference signal contained in the input signal. An output signal of the waveform integrator circuit is correlated with the output signal of the transversal filter by the correlator.Type: GrantFiled: May 18, 1981Date of Patent: June 21, 1983Assignees: Tokyo Shibaura Denki Kabushiki Kaisha, Nippon Hoso KyokaiInventors: Shunichi Onishi, Masaharu Obara, Masaru Sakurai, Junzo Murakami, Shinichi Makino
