Title: Phased array antenna device
Inventor: TAMAMA TETSUO
IPC: H01Q3/30
Filed: 1982-03-05
Abstract: PURPOSE:To avoid a change of beam directional angle even to the variations of frequency, by using a phase shifter having specific frequency characteristics. CONSTITUTION:When an electric wave of a frequency (f) is fed through an input/output terminal 5, the electric waves are radiated as conventional from radiators 1-1-1-4 with a beam directional angle theta. When an electric wave of a frequency (f+DELTAf) is fed through the terminal 5, the electric waves having a phase difference equivalent to a phase degree of phi+DELTAphi between adjacent radiators are radiated from radiators 1-1-1-4 via phase shifters 6-1-6-3. In this case, the phase shifter has the frequency characteristics of DELTAphi=(DELTAf/f)phi, where phase degree phi=(2pidf/c)sintheta, frequency (f), changing degree DELTAphi of phase, and changing degree DELTAf of frequency respectively. Therefore phi+DELTAphi= 2pid(f+DELTAf)/c sin(theta+DELTAtheta) is satisfied, where the beam directional angle theta+DELTAtheta. If the above equation is substituted here, phi=(2pidf/c)sin(theta+DELTAtheta) is obtained. Thus the beam directional angle has no change even to a frequency change DELTAf an long as DELTAtheta=0 is satisfied.

Title: Affine conversion and display system by outline data generation of character font
Inventor: KAWAMURA HAJIME
IPC: B41J2/485
Filed: 1990-02-15
Abstract: PURPOSE:To rotate a character by an optional angle and to enlarge or reduce the character with optional magnification by generating data on outline segments of the character font and then performing the affine conversion of the outline segments. CONSTITUTION:Character font data as an object of affine conversion are read out. When the character font of, for example, a 5X5-dot character 'A' is processed, hatched dots are bit-on dots and the outline segments of the bit-on dots are represented as solid lines. Dot outline segments which are present double are deleted and segments which are on one straight line are put into one to leave the outline segments of the character 'A'. The affine conversion of the outline segments of the character font which are obtained as mentioned above is carried out to obtain the character font data after the affine conversion of the character A. Consequently, the character can be rotated by an optional angle and enlarged or reduced with optional magnification and the resulting character can be displayed.

Abstract: PURPOSE:To cancel misconvergence by making one of a normal winding portion and a reverse winding portion of auxiliary coils, which compose an auxiliary magnetic field generation means, connected in parallel with two diodes which are connected in opposite polarities to each other. CONSTITUTION:Auxiliary coils 20, which compose a pair of auxiliary magnetic field generation means 15 and 16 where auxiliary magnetic fields are added to beams generated by central electron guns B, G, and R, are composed of a normal winding portion 20a and a reverse winding portion 20b which are reversely related to each other in their winding directions.

Filed: 1978-03-30
Abstract: PURPOSE: To considerably reduce the amt. of a basic slag making material used in a steel making process in a converter or the like and the amt. of slag formed, by previously desiliconizing hot iron with iron oxide, etc. prior to oxidation refining to steel in a converter or the like.  
     CONSTITUTION: Hot iron manufactured in a blast furnace is first desulfurized outside the furnace. Next to the iron is added solid iron oxide of total Fe content above 60%, e.g. mill scale or sintered ore. In case the trivalent Fe content of the solid oxide is below 0.5% and above 5%, the solid oxide is supplied at a rate of 3W10 kg/min and 1W7 kg/min to 1 ton of hot iron, respectively, whereby Si in the hot iron is preferentially oxidized and removed as slag. The hot iron thus desiliconized to low Si content is then oxidized by oxygen blowing in a converter to be refined to steel by decarburization and dephosphorization. Since very little SiO 2  is formed, the amt. of CaO to be added as a slag making material is considerably reduced and formation of slag is inevitably minimized.
