IPC: H04B14/06
Filed: 1977-10-18
Abstract: PURPOSE:To suppress the occurrence of cross modulation distortion for two signals without deteriorating the frequency characteristic of a transmission band and S/N, by attenuating enough high-band components of input signals in the SCPC satellite communication system, etc. CONSTITUTION:Input signals, which consist of sound signals or MF signals, from an exchange are coded dependently upon delta modulation in delta modulator 13 after having high-band components suppressed enough by input equalizer 12 which has characteristic A, and the coded output is transmitted through a modulator and a transmitter.

Abstract: PURPOSE:To enable to fusion-bond in a constant size adapted for fusion-bonding workpieces of the prescribed shape by stopping the drives of a motor and an oscillator when the content of a preset counter reaches the specific value and stopping the fusion-bonding operation. CONSTITUTION:Two thermoplastic resin sheets are interposed between a machining surface 11 and a press roller 12, the total feeding distance of workpieces is set in advance in a preset counter 19, a drive command signal S0 for outputting a start pulse P0 is outputted from an operation switch 14, and is applied to a feed controller 15 and an oscillation controller 16. A motor 8 is driven to rotate a machining horn 6, an oscillator 13 is driven to allow the horn 6 to vibrate in a supersonic frequency, and the workpieces are integrally heated and fusion-bonded. A position signal generator 18 continuously detects the rotating speed of the motor 8 and outputs a rotation signal Sn responsive to the feeding distance of the workpieces, thereby gradually decreasing the counted content of the counter 19.

Abstract: PROBLEM TO BE SOLVED: To enhance smoothness of a substrate surface and uniformity of a surface shape by mechanically subjecting the substrate for magnetic recording to a polishing treatment, then irradiating the surface with a laser beam. SOLUTION: The substrate of the substrate D to be subjected to surface treatment is subjected to a mechanical polishing treatment and the surface roughness thereof is specified to 1 to 20 nm. Next, the substrate D is supported at a substrate supporting section 4 and the laser beam is emitted from a laser beam source 2. The laser beam is made incident on a uniform distribution forming optical system 3 from which the laser beam is emitted after setting in such a manner that the energy density is uniform and that the output per unit area attains 200 to 300 mJ/cm<2> . The laser beam is cast over the entire part of a belt-like region A along the radial direction of the substrate D supported with the substrate supporting section 4.  At this time, the laser beam to be cast to the substrate D is made uniform in the energy density by the uniform distribution forming optical system 3 and, therefore, the energy is applied over the entire part of the irradiation region A without deviation.
