Filed: 1990-11-15
Abstract: PURPOSE:To reduce the circuit scale and to decrease the power consumption by using two adjacent channels for talking between slave sets and processing two channels of high frequency and IF conversion sections at a batch. CONSTITUTION:Frequencies f1, f3 received from an antenna are processed by a high frequency amplifier section 3, a 1st mixer 4, a BPF 5 and a 2nd mixer 6 altogether. Since the signals by two channels are processed at a batch, the pass band is different from that of the BPF 5 and an output signal of the mixer 6 is separated into signals of each channel by two BPFs 7, 10 whose pass bands are different, and the signals are respectively processed by IF amplifier sections 8, 11 and demodulation sections 9, 12 and voice signals Bf1, Bf2 are obtained. On the other hand, in the transmission processing, in the case of interslave set talking, the voice signals Bf1, Bf2 are respectively modulated as voice signals Bf4, Bf3 and the resulting signal is sent to an opposite slave set at frequencies f4, f2. The Bf4, Bf2 are respectively modulated by modulation sections 15, 16 each comprising a VCO and synthesized at an adder circuit 17 and amplified by a high frequency amplifier section 18.

Title: Formation of thin film and sputtering device
Inventor: YAMADA YOSHIAKI
IPC: C23C14/04
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To form a film on the bottom of an opening part having a high aspect ratio with a good coverage and high utility of a target by a sputtering method. SOLUTION: A substrate 7 is arranged vertical to the direction in which most sputtered grains are released to a target 4, furthermore, the distance between the target 4 and the substrate 7 is made longer than the diameter of the substance, and, moreover, the average free path of a sputtering gas is made longer than the distance between the target 4 and the substrate 7, by which the sputtered grains are made incident on the substrate at an angle close to that vertical to the substrate without scattering the sputtered grains. Thus, film can be formed on the bottom of an opening part having a high aspect ratio with good coverability and good using efficiency of the target 4. Furthermore, since the substrate 7 is rotated in the plane, the uniformity in the plane of the substrate is also good.
