IPC: H03F1/02
Filed: 1990-01-29
Abstract: PURPOSE:To improve the linearity of power amplification when an input signal level is small by keeping a bias voltage to be a prescribed value or above when an envelope signal level of the input signal to a power amplifier is small. CONSTITUTION:The input signal of a power amplifier 4 is obtained by modulating a modulation signal inputted to a modulation input terminal 1 at a modulation circuit 2. A coupler 3 branches the output of the modulation circuit 2 and applies it to a envelope detector 5 and the envelope detector 5 detects the envelope of an output signal of the modulation circuit 2. A signal conversion circuit 6 gives the output to keep the output voltage of a DC voltage control circuit 7 to a prescribed value or above to a DC voltage control circuit 7 when the signal level of the envelope is smaller than the predetermined value and the DC voltage control circuit 7 gives a DC bias voltage to the power amplifier 4 based on the output of the signal conversion circuit 6.

Abstract: PURPOSE:To observe a wide field without lowering a transmitting antenna gain by a method wherein a sub-pulse is transmitted by a transmitter and a prescribed piece of phase information is given to a phase shifter for every sub-pulse by a beam steering computer so as to make it conduct phase scanning for each sub-pulse. CONSTITUTION:Transmitting antennas 7 are disposed linearly in the number of L, and a phase shifter is connected to each of them. The amount of phase shift of the phase shifter scanning a beam in the direction of an angle theta1 is given as -2pidK sin theta1/lambda by abeam steering computer 6. In this expression, mark (d) denotes the respective intervals of the antennas 7 and K an element number, which takes values of 0, 1, 2...L-1. Now, a phase amount represented by -2pidk sin thetan/lambda is given in accordance with the direction theta1, theta2...thetaL of a running beam. Then, a transmission pulse of a pulse width tau2 is divided into L, the phase of the phase shifter is varied at every tau2/L, and the beam is scanned in accordance with each of sub-pulses P1 P2...PL. By this method, the maximum detected distance in one transmission pulse is improved by L<1/4> times higher than usual when a target is detected.

Abstract: PURPOSE:To send out a pattern always at the same timing by controlling characters or image patterns which are stored in a buffer from a host computer by means of a raster buffer control part at a timing for reading a pattern based on an instruction from an operating panel. CONSTITUTION:Printing data to be transferred from a host computer 1 is stored in a page buffer 2 to the limit of a single page.

Abstract: PURPOSE:To miniaturize a decurl mechanism by providing a moving means for moving one of a decurl member and a sheet guide member so as to urge the moving means in a sheet curve increasing direction, and by controlling the movement of the moving means in a curve decreasing direction. CONSTITUTION:A sheet 55a is conveyed in the direction (e) by rotation of a platen roller 56a in the direction of the arrow (a). In synchronization with the rotation of the platen roller 56a, a clutch flange 10 is rotated integrally with a clutch-gear 8 until a recess 10e makes contact with a locking pawl 16. When the recess 10e makes contact with the locking pawl 16, a spring clutch 12 becomes free so that the clutch gear 8 races with respect to the clutch flange 10. Meanwhile, a shaft 4 rotates an arm 2 in the direction (-b) by an urging force in the direction (f) so as to move a guide shaft 18 which is then stopped balancing with a tension force of the sheet 55a. With this arrangement, the sheet 55a is wound onto the guide shaft 18 in the curling direction, and then is curved in a direction reverse to the curling by a decurl shaft 72, thereby it is possible to remove the curling.
