Title: Power amplifier
Inventor: YAMAMOTO HIROYUKI
IPC: H04L27/22
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To decrease a delay time of digital signal processing by configuring the power amplifier of the negative feedback linear modulation system digitally and using a high speed sampling frequency for addition of negative feedback. SOLUTION: A digital orthogonal demodulator 13' separates a received signal into an in-phase component I and a quadrature component Q with a sampling frequency and a phase shift circuit 14' gives the in-phase component I to an adder 2-1, which applies negative feedback to the in-phase component I of the input signal to a modulation wave generator 1. Similarly the separated quadrature component Q is fed to an adder 2-2 via the phase shift circuit 14' and the adder 2-2 applies negative feedback to the quadrature component Q of the input signal from the modulation wave generator 1. The phase shift circuit 14' adjusts a phase of an output signal from the modulation wave generator 1 to be in matching with a phase of an output signal from the digital orthogonal demodulator 13'.  Since the input signal and the feedback signal are summed at the sampling frequency, the effect of a delay caused in the digital signal processing is reduced.

Filed: 1995-04-06
Abstract: PURPOSE: To reduce a transmission loss and mutual modulation distortion by commonly supplying a power supply current from one power separator mounted at the feeder of an outdoor tower top amplifier part to other plural reception amplifiers on the top of a tower as well. CONSTITUTION: An incoming radio signal is inputted through an antenna 20 dedicated to diversity reception at the top of the tower, a reception amplifier 8 at an outdoor tower top amplifier part 1, a feeder and an indoor tower top amplifier part 2 to a diversity circuit 11. The power supply current to the reception amplifier 8 is passed through a power superimposer 10 at the indoor tower top amplifier part 10 and supplied through the feeder while being separated from the feeder by the power separator 9 at the outdoor tower top amplifier part 1. In this case, the power supply current is commonly supplied from one power separator 9 to other reception amplifiers 6, which are adjacently installed at the top of the tower, for diversity reception antennas 30 as well.  Since no mechanical connection part for inserting the power separator 9 and no power superimposer 10 are required at the feeder for a transmission/reception antenna 30, non-linearity is prevented from being generated.

Abstract: PURPOSE:To effectively use one telephone line by a facsimile equipment and a telephone set by bringing the state into the automatic reception state when a facsimile signal is detected within a prescribed time and outputting a telephone call signal when no facsimile signal is detected. CONSTITUTION:When the mode is set to the automatic reception mode, a facsim ile equipment detects an incoming data by a recording section 4 and records the data automatically. When no facsimile signal is sent even when a prescribed time elapses, a control circuit 1 drives a signal generating circuit 9 to use a speaker 10 thereby informing a telephone call to an incoming side person, sends a call signal to a telephone line L to inform a caller the state of calling. When the incoming side person hooks off a handset and operates a prescribed button on a key board 6, the circuit 1 controls a line switch circuit 7 to connect a telephone set 8 to the line L, then the talking with the caller is attained. When the incoming party, however, does not reply within a prescribed time, the circuit 1 stops the call signal and cuts off the telephone line and enters the standby state.

Title: Ink jet recording apparatus
Inventor: IMON MASAHARU
IPC: B41J2/165
Filed: 1992-03-03
Abstract: PURPOSE:To prevent the fixing and emission inferiority of ink and to enhance the reliability of a product by enhancing the sealability of an emitting orifice forming surface by providing a gap uniformizing the contact state of a sealing surface by the elasticity of a cap between the cap and a cap holder. CONSTITUTION:The sealing surface 72 of a cap 22 does not always uniformly come into contact with an emitting orifice forming surface 81 because of dimensional irregularity of respective parts. Therefore, when a part of a sealing part 74 comes into contact with the surface 81 prior to coming into contact with other part, the previous contact part is ready to increase in contact force as compared with other part. Herein, since a desired gap 73 is present between the rear 75 of the sealing surface 74 of the cap 22 and a cap holder 65, a part where strong contact force is applied can be bent in the direction escaping from the emitting orifice forming surface 81 by the elasticity of the cap 22. Therefore, the sealing surface 74 of the cap 22 balances when it uniformly comes into contact with the emitting orifice forming surface 81 as a whole and always uniformly sealed with respect to the emitting orifice forming surface 81. Since the emitting orifice forming surface 81 is uniformly sealed, the excessive stress action of a part of the cap 22 is prevented.
