Title: Mixer circuit
Inventor: HASEGAWA MAKOTO
IPC: H04B1/26
Filed: 1988-01-25
Abstract: PURPOSE:To improve the degree of image suppression and the frequency characteristic by extracting an image signal of an image rejection mixer and applying phase or level feedback to part of a hybrid being a component. CONSTITUTION:IF output currents I1, I2 caused in single mixers 1, 2 give signals whose amplitudes are the same but whose phases are shifted by 90 deg. through an IF hybrid 10, and the phase of image signals is opposite to each other at an IF terminal 7 and they are cancelled together. Only the image signal appears at an image terminal 8. The undesired image signal component is terminated by an image termination element 9, the image signal component is extracted from the part and the level and phase of an RF signal are subjected to fine- adjustment by an adjustment circuit 12 through a feedback circuit 11 so as to maximize the image component. Thus, most of the image component is attracted at the image terminal and the leakage to the IF terminal is decreased.

Abstract: PURPOSE:To release surely a strobe signal by inputting the exclusive OR output between a transmission request signal and one output of an FF to the clock terminal of the FF and feeding back the other output of the FF to the input of the FF. CONSTITUTION:A transmission request signal SND and an output Q of the FF are inputted to an exclusive OR circuit EOR, and the output is inputted to a clock terminal C of the FF. An output Q' is outputted as a strobe signal COM' and is inputted to a data terminal D. A response signal ACK is inputted to a reset terminal R'.

Title: Ghost eliminating device
Inventor: MURATA TOSHINORI
IPC: H04N5/21
Filed: 1982-02-03
Abstract: PURPOSE:To obtain a modulated video signal having no ghost, by controlling properly the gain of a delay signal on a basis of the output of a subtractor. CONSTITUTION:A signal inputted to an IF signal input terminal 9 is detected by a detector 11, and its envelope components are sent to a modulator 12, and the signal is modulated again to become an IF signal. The output of the modulator 12 is inputted to a surface acoustic wave element 1; and when the delay time between plural electrodes provided in the element 1 is set to an integral multiple of the period of a modulating carrier signal, phases of respective electrodes coincide with each other. Therefore, the output of an amplifier is in-phase or anti-phase in accordance with the polarity of the gain of the amplifier. The output of the element 1 and the output of a reference signal generator 7 are inputted to a subtractor 8, and the subtractor 8 outputs an error signal. This error signal is sent to an automatic gain control amplifier 13 to determine the gain of the amplifier 13. When a signal including ghost is applied, the gain of the amplifier is reduced, and a video signal with ghost eliminated is obtained.

Filed: 1978-02-14
Abstract: PURPOSE: To prevent the local bending of a cladding tube and the pitch change of a wire spacer, by means of forming a cladding tube in a bending shape of a spiral form, and of winding up a spiral wire spacer.  
     CONSTITUTION: A processing is so effected as to bend a cladding tube 40 in a spiral form, and a full or an empty wire spacer 13 is so wound up under a little tension load as to be twisted together by the spiral bending of the cladding tube 40, and the both ends of the wire spacer are fixed at end plugs 14a, 14b. By such means, because that the tension of the wire spacer becomes to zero, the excess stress is never acted on the cladding tube, and the local bending can be prevented. And the transfer to the axial direction of the wire spacer 13 can be controlled owing to the holding action due to the bending of the cladding tube, thereby the pitch of winding is never changed, and the vibration of the cladding tube due to the change of the pitch of winding, and the change of the coolant flow path can be prevented.
