Filed: 1978-03-09
Abstract: PURPOSE:To enable to compensate the identification degree of cross polarization as a process of demodulation operation with slight addition of circuits, without providing the compensation circuit for polarization identification degree separately from the demodulator. CONSTITUTION:In performing radio transmission for the high speed digital signal in common use of vertial and horizontal polarization with quadruple differential phase modulation, the input signal is sectioned into two with the division circuits 3 and 4; one is used for the demodulation of desired signal and another is for compensating interferring vector leaked to horizontal or vertical side. In this case, the residual of the vertical interferring waves leaked is detected with the synthesis circuit 8, reference carrier is reproduced with the inverting modulation circuit 9 with the semi-fixed phase shifters 13,14,17 and 18 causing the waves having the phase difference of 90 deg., and this reference carrier is made by phase detection with the horizontal phase detectors 10,11 and the interferrence wave vector detectors 19,20 and the vertical component is fed to the inverting modulation circuit 9 as inverting modulation. Further, to the vertical component, the similar operation is made at the vertical polarization circuit constitution 5 for compensation.

Abstract: PURPOSE:To automatically print an image on that page even when a band bit map error generates by a method wherein image data for one page is bit- map-expanded on a bit map memory, and printing is performed base on it. CONSTITUTION:An external RAM 31 is used as a bit map memory when an image expansion is performed by a full bit map method.

Title: Regulation of die gap
Inventor: IGUCHI KATSUHIRO
IPC: B29C48/08
Filed: 1986-02-12
Abstract: PURPOSE:To obtain a method of regulating die gap, by which the amount of screwing-in and -out of respective bolts are easily obtained, by a method wherein die bolt loads are repeatedly changed so as to make the amounts of displacement on arithmetic operation fall within the allowable range and then the amounts of the respective operating bolt loads to change are calculated from the resultant final die bolt loads. CONSTITUTION:First, a certain fixed load P0 to generate off-set values eoi, which is added to the target amounts of displacement DELTAei of a die gap, is set so as to calculate the amounts of displacement eoi developed at respective positions of a movable die blade under the condition that the certain fixed load P0 is applied. Secondly, after the target amounts of displacement on arithmethic operation ei=eoi+DELTAei is set, the arithmetic operation is judged whether it is for the first time or not. When the arithmetic operation is performed for the first time, the amounts of loads to change Pi at the respective positions are set to be a certain fixed load Pi, which is determined arbitrarily so as to calculate the amounts of displacement of die gap at the respective positions eoi under the condition that Pi is employed as the initial value of the amounts of loads to change at the respective positions. Thirdly, the amounts of loads to change Pi are corrected by the ratio of the target amounts of displacement ei on arithmetic operation to the amounts of displacement of die gap at the respective positions eei on arithmetic operation so as to calculate the amounts of displacement of die gap at the respective positions eoi on the basis of the corrected Pi. Thus, the arithmetic operation is repeatedly performed until the resultant amounts of displacement of die gap eci fall within the allowable range.
