Title: Saturation preventing circuit in cartesian feedback circuit
Inventor: HAMAZAKI TOSHINORI
IPC: H04B1/04
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a maximum operating level setting operation before transmission in the Cartesian feedback circuit of a radio transmitter. SOLUTION: The phase differences between a common phase error signal I3, an orthogonal error signal Q3 and a local common phase demodulation signal I4, a local orthogonal demodulation signal Q4 in the Cartesian feedback circuit is obtained by a phase comparing circuit 12. Based on the phase difference, a saturation detecting circuit 11 detects saturation at the time of transmission. An amplitude limiter circuit 10 executes the amplitude control of the same phase input I1 at the time and an orthogonal input Q1. Since saturation can be detected at the time of transmission, maximum level adjusting operation before transmission is unnecessitated.  Even in the radio transmitter where a maximum level adjusting operation before transmission is not permitted, the Cartesian feedback circuit can be used to improve the linearity of modulation to reduce unnecessary radiation outside of a band to eliminate disturbance to an adjacent channel.

Abstract: PURPOSE:To provide a printer which prevents generation of inferior prints by providing an electric charge to ink particles while shifting the phase of a leak detection signal of a narrow width with the help of a video signal during nonprinting action and processing a high pressure leak when the electric charge is detected with all the phases.

Ink settles between deflection electrodes 8, 9 to generate a condensate 19 which approaches a certain distance to the said electrodes causing an electric discharge. During nonprinting action, a leak detection signal of either of theta1-thetan is appied to an electrically charged electrode 6 and this is detected by means of the sensor 10. The leak detection signal is created by dividing an oscillation cycle T equally by 1/n and shifting the divided n times by (1/n)XT. One phase condition is held until electric charging into the ink, picking up of an induction current by means of a sensor and judgement with a divaluation circuit are completed. When a detection signal has been detected by all the phases, a high pressure leak is treated.

An inverter commutation failure prevention circuit is coupled to the alternating current network for detecting abnormal voltage conditions and for producting a control signal functionally related to any deviation in the alternating voltage from the expected voltage condition. The control is responsive to the control signal for reducing the electrical angles of the trigger pulses provided to the valves.

Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To relieve blocking phenomenone and smoothing phenomenone or the like by interpolating pixels through the use of a state value (context) of pixels around a pixel formed by interpolation. SOLUTION: A position of an interpolation pixel to be interpolated is decided and a context is obtained. Then an interpolated value INP[P] of the interpolated pixel is calculated. Then a current critical object value THRc[t] is compared with a calculated interpolated value INP[P] (S370), and when the interpolated value INP[P] is larger than the critical object value THRc[t], '1' is set to the interpolated pixel (S372) and when the interpolated value INP[P] is smaller than the critical object value THRc[t], '0' is set to the interpolated pixel (S374). All critical object values are applied to a current interpolated value to check the possibility of hit (S390). After the interpolation is applied to all pixels in a binary image, the critical object value whose frequency of the hit is the highest is set as a critical value of the interpolated value.

Abstract: PURPOSE:To control the end necessary pressure at about constant level with no energy loss by setting previously the targeted control pressure for each flow rate of a pump and then changing the targeted pressure according to the variation of the pump flow rate. CONSTITUTION:A pressure signal S1 is sent to a control part 21 frfom a pressure detector 16 is response to the increase/decrease of the using flow rate. The part 21 calculates the corresponding targeted control pressure SV from the detection signal sent from a flow rate detector 20 and according to the relation between the prescribed pump flow rate and the targeted control pressure set for each flow rate. Then a frequency output signal with which the pump discharge pressure P is set close to the pressure SV is obtained from the pressure SV and the signal S1. Then said output signal is outputted to an inverter 22. Thus a motor 11 is varied in the direction opposite to the changing direction of the pressure value shown by the detector 16. Then the pressure SV is obtained through control.
