Title: Agc amplifier
Inventor: ARAMAKI SHIGETAKA
IPC: H03G3/30
Filed: 1987-09-18
Abstract: PURPOSE:To finely control the output of a power distributor by controlling a variable attenuator between the power distributor and a detector to input a value obtained by comparison and amplification with the output of a standard voltage circuit to a variable attenuator in the preceding stage of said variable amplifier. CONSTITUTION:The extent of attenuation of a variable attenuator 11 provided between a power distributor 5 having an RF output terminal 2 and a detector 6 is finely controlled through a driving circuit 13 by a command 12 from the ground. The output of the detector 6 which is finely controlled is compared with the output of a standard voltage circuit 7, and the bias current from a comparing amplifier 8 is reduced by the extent of attenuation to reduce the extent of attenuation of a variable attenuator 13. Since the gain of an amplifier 4 and the insertion loss of the power distributor 5 are fixed, the output of the RF output terminal 2 is increased by the extent of attenuation. Thus, a circuit is constituted which requires the remote control based on the command from the ground and is suitably mounted on a satellite.

Title: Optical waveguide device
Inventor: KO BIBI
IPC: G02B6/122
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To obtain high dispersion of birefringence in a wide wavelength range by forming a plurality of cores each having a higher refractive index than that of a clad on a dielectric substrate to be used as the clad so as to obtain the distribution of the refractive index showing a plurality of maxima. SOLUTION: When a Ti diffusion method is used, for example, a patterned Ti metal film is deposited on a LiNbO3 substrate 111 and diffused into the substrate by heat treatment to form a plurality of cores 112 having a high refractive index near the surface. During the heat treatment, external diffusion of Li2O is caused to decrease the trapping effect for light. To prevent that, the treatment is performed in Li2O or LiNbO3 powder. For example, in a proton exchange method, LiNbO3 is dipped in a fused liquid of benzoic acid (C6 H5COOH) at about 210 to 250 deg.C for several ten minutes to exchange Li+ and H+ so that a region having a high refractive index can be obtained. Thus, the distribution of the refractive index shows two peaks n1 corresponding to the two cores 112 formed by the Ti diffusion method on the LiNbO3 substrate 111.

Filed: 1994-09-28
Abstract: PURPOSE: To simplify the recording and reproducing processing system for a SECAM modulated color signal and also to stabilize color picture quality. CONSTITUTION: An SECAM video signal is separated into a luminance signal and the modulated color signal by a luminance signal and color signal separating circuit 15, and the modulated color signal is inputted to a multiplier 191 and a demodulation circuit 17. A voltage control oscillation circuit 18 is set for its oscillation center frequency to 3/4 or 5/4 of a carrier frequency of the modulated color signal, oscillating with a frequency corresponding to a voltage of a demodulated output signal inputted from a demodulation circuit 17 and supplying an oscillation output to the multiplier 191. Consequently, the modulated color signal equivalent to 1/4-stepdown demultiplied one is outputted from an LPF 192. This signal is added to an FM luminance signal outputted from a luminance signal processing circuit 16 by an adder 20, becoming the recording SECAM video signal. Consequently, the circuit structural scale is reduced when compared with a conventional one, while circuits to exert an adverse effect upon the color picture quality are eliminated, thus obtaining the stable color picture quality.

Filed: 1988-09-16
Abstract: PURPOSE:To obtain inexpensive constitution by dispensing with the accurate synchronism with pulse beam by detecting the attenuation value of an electric signal at the same time interval at every output terminal of a semiconductor position detection element and calculating a position signal on the basis of predetermined operation. CONSTITUTION:Pulse beam 1 is incident on the beam detection surface 21 of a semiconductor position detection element 2 and sampled in timings P1, P2 by sampling circuits 9, 10 through capacitors 3, 4 and operational amplifiers 5, 6. The difference quantities of currents between the timings P1, P2 appear in the outputs of the circuits 9, 10. The ratio of the difference between the difference quantities and the sum of said quantities is regardless of the time constant of the element 2 and changes linearily with the respect to a change of an incident position X and corresponds to a position signal. Therefore, even when the interval between the timings is varied, there is no effect and it is unnecessary to accurately perform the synchronism with a pulse beam source and a circuit can be inexpensively constituted.

Title: Communication equipment
Inventor: IWAHASHI KOJI
IPC: G09F9/00
Filed: 1987-09-18
Abstract: PURPOSE:To prevent the generation of malfunction such that the frequency of an inner reference oscillator is corrected following an disturbing wave by allowing a receiving band restricting intermediate frequency filter to pass a narrow band filter prior to the input of an intermediate frequecy signal to an error voltage generating phase comparator. CONSTITUTION:The band width of the intermediate frequency passing filter 16 is set up to the shear width of the 2nd intermediate frequency due to a frequency error between the output of a voltage controlled reference oscillator whose voltage control is not executed and a receiving signal to be received. Even if a regular signal is received when the oscillation frequency of the oscillator 4 is shifted by a value corresponding to the frequency error, the 2nd intermediate frequency signal is entered into the intermediate frequency passing filter 16 and following operation is surely executed. Since the band width of the filter 16 is restricted narrower than that of a filter 8, the following operation of the disturbing wave or the like can de suppressed.

Abstract: PURPOSE:To promote confidentiality when incoming message is reproduced by providing to an automatic answering unit with a means to send remote control signals in accordance with the remote control signals from a telephone set. CONSTITUTION:When a telephone set dials the extension number of an automatic answering unit 51 through button operation, the contact IX1 is turned on and the telephone set 4 is connected to the extension link 6 and to the unit 51 by the known control procedure. If the telephone set 4 sends the commands to the recording part such as rewinding, reproduction and fast forwarding, as remote control information, through button operation, the controller 14 controls the signal generator 10 to send the corresponding remote signals. The unit 51 receiving the signals operates in accordance with the commands and sends the incoming messages recorded while absent to the extension link 6 after reproducing them. Therefore, at the telephone set 4, the incoming messages can be heard through the receiver and confidentiality is kept even when there is a third party nearby.
