Title: Excitation regulator for ac generator
Inventor: SAWA KUNIHIKO
IPC: H02P9/38
Filed: 1979-07-13
Abstract: PURPOSE:To prevent malfunctioning due to strained waveform of the generator  voltage with a simple construction by means of a semiconductor switch and a current absorbing circuit provided in parallel on the DC side of the rectifier for feeding  the field winding with the voltage and current components being vector-combined. CONSTITUTION:The current and voltage components drawn through the power current transformer 102 and the AC reactor 103 are vector-combined at the AC input side of the rectifier 101. The current to be fed to the field winding 2 from the rectifier 101 is controlled with the semiconductor switch 100. Connected in parallel to the field winding 2 is the current absorbing circuit 104 for absorbing the differential current between the DC output current of the rectifier 101 and the field current when the semiconductor switch 100 is OFF. Thus, the excitation regulation with the semiconductor switch on the DC side can prevent malfunctioning due to strained waveform of the generator voltage.

Abstract: PURPOSE:To transmit clear images and to enable speedy transmission by unnecessitating transmission after temporary printing-out by executing the FAX transmission of information on the display screen of the multi-functional telephone set after converting the information to the image density of a FAX. CONSTITUTION:Corresponding to an input signal, an NCU 1 distributes data communication, FAX communication and telephone communication to a data communication part 4, FAX communication part 3 and telephone part 2 respectively. In the case of the data communication, data stored in the data communication part 4 are converted to image signals by a control parts and stored in the part. In the case of the telephone communication, the information is converted to an image by the control part and displayed at the LCD unit of a display part 6. The image sensor of the FAX part 3 successively reads the displayed images, converts the extracted data to the image density and stores them in a memory. Finally, the control part 5 reads out the stored image signals and transmits the FAX images through an interface and an interface connector 8. Thus, the clear images are transmitted while omitting a process for temporary printing-out.

Filed: 1990-04-04
Abstract: PURPOSE:To dispose a mechanism for pressing a recording medium near nozzles to improve a printing quality by a method wherein fixing screws for fixing a case member covering an ink jet substrate to an ink jet recording head are disposed vertically to a recording medium feed direction. CONSTITUTION:Printing paper 9 is disposed horizontally and fed from the right to left of an X axis in the figure by paper feed rollers 10. Presser boards 8 keep a constant Z-axial distance between an ink jet recording head 1 and the printing paper 9 by pressing the printing paper 9 on a flat platen 7. The head 1 delivers ink downward in the Z-axis direction while moving in the Y-axis direction to conduct recording. A mask plate 4 as one of case members of the head 1 is fixed to a holder 6 with fixing screws 5, which are juxtaposed in the Y-axis direction of a nozzle line arranged in the X-axis direction of the head 1. In this construction, there is no fixing screws 5 on the upper and lower sides of the nozzle line of the head 1 in the X-axis direction. Thus, the both sides of the holder 6 can be chamfered in the X-axis direction of the nozzle line, whereby the presser board 8 can be disposed near the nozzle line. A Z-axial distance between the nozzles and the recording medium can be kept constant.
