Title: Intermediate frequency signal processor of fm receiver
Inventor: ISHIDA KOUJI
IPC: H04B1/10
Filed: 1982-06-11
Abstract: PURPOSE:To reduce distortion generated by a filter without degrading selectivity by permitting a control signal to cancel distortion in a signal of the 2nd intermediate frequency when converting an FM received signal from the 1st intermediate frequency to the 2nd intermediate frequency. CONSTITUTION:The FM received signal is converted by a front end 21 into a signal of frequenct f1, i.e. the 1st intermediate frequency IF, which is applied to a BPF22 and a delay device 25, so that transmission distortion appears at the output of the BPF22. A mixer 23 performs conversion to frequencies f1+ or -f2 by a signal of frequency f2 from a VCO31 and an LPF24 extracts the 2nd IF signal of frequency f1-f2. The 2nd IF signal and the 1st IF signal from the delay device 25 are mixed by a mixer 26 and a BPF27 extracts a signal of frequency f2. The 1st and the 2nd IF signals have the same frequency shift direction, so a modulated signal S is canceled to obtain only the distortion D. The distortion D is made into fine distortion (d) through the negative feedback loop of the system with an input to a detector 8. The distortion (d) detected by the detector 28 is passed through an LPF29 and phase-inverted and amplified by an inverting amplifier 30 to control the output of the VCO31 so that the distortion D in the 2nd IF signal is canceled.

Inventor: FURUKAWA CHISATO
IPC: H01L21/205
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To activate a p-type impurity that is added into a gallium nitride compound semiconductor more efficiently, by performing setting so that a larger fixed amount of inert gas than the specific amount of p-type impurity being added into gallium nitride compound semiconductor film can be electrically activated. SOLUTION: A GaN film including a p-type impurity is formed on a sapphire substrate. Then, an annealing treatment is performed to a substrate where the GaN film is formed. A substrate 30 is installed at the center of a crystal tube, and the inside of the crystal tube is substituted with N2 . While a constant amount of N2 that flows in parallel on a substrate surface is being supplied, a substrate temperature is increased and the temperature is maintained. After that, the temperature of a substrate is cooled to a room temperature. The ratio of an acceptor concentration to the Mg impurity concentration in a GaN film is increased by approximately 1%, thus obtaining a stable and high activation rate.
