Title: Image synthesizing method for manual scan type image scanner
Inventor: RI TOURO
IPC: H04N1/107
Filed: 1992-09-11
Abstract: PURPOSE:To provide a method to perform the alignment of a part where video read by a manual operating type image scanner 10 are overlapped. CONSTITUTION:Two sets of video -Y1, +Y2 read in by an image scanner are overlapped partially, and they are displayed on a display part. At this time, aberration occurs, therefore, A1 of -Y1 and B1 of +Y2 are selected and instructed at one terminal part as a first point where they should coincide with each other. Those are displayed by superimposing, and the amount of travel between A1 and B1 at the first point is decided. A2 of the inverse of Y1 and B2 of +Y2 are selected and instructed at another terminal part as a second point where they should coincide with each other, and they are displayed by superimposing, then, the amount of travel between A2 and B2 at the second point is decided. An angle theta of rotation at which +Y2 should be moved is decided from the amount of travel at the first and second points, and the parallel displacement of +Y2 is performed so as to obtain relation A1=B1. Thence, the angle theta of rotation is rotated centering about a point A1=B1. Thereby, both images can coincide with each other, and they can be synthesized.

Inventor: TATSUHIRA YASUSHI
IPC: H03L7/10
Filed: 1986-11-12
Abstract: PURPOSE:To widen the oscillating range without decreasing the oscillation accuracy by providing plural voltage controlled oscillator so as to select a voltage controlled oscillator capable of being locked. CONSTITUTION:The switch 9 selecting an output signal of plural number of voltage controlled oscillators 7, 8 and changeover means 10, 11, 12 controlling the changeover are provided. Either a 1st voltage controlled oscillator 7 or a 2nd voltage controlled oscillator 8 capable of being locked is selected based on the changeover of the switch circuit 9 depending on the count of the changeover state of the switch circuit 9 depending on the count of the output signal state of a loop filter 3 by the counter 11. Thus, the oscillating range of the voltage controlled oscillator of the PLL circuit is doubled more than that of a conventional oscillating range and the PLL circuit is locked to a wide variety of the frequency signal obtained at an input terminal 1. Since the oscillating range of each voltage controlled oscillator 7, 8 is not widened regardless of the widened locking range, the accuracy of the oscillation signal is not deteriorated.

Abstract: PROBLEM TO BE SOLVED: To produce a hydrogen storage alloy having low oxygen concn. from a vanadium base alloy having high oxygen concn. in a low cost by heating and melting the vanadium base alloy raw material together with at least one kind of deoxidizer. SOLUTION: The vanadium base alloy raw material (about 2000-20000 ppm oxygen content) in low cost obtaining a part or all thereof with a thermit reduction process is heated and melted together with at least one kind of the deoxidizer. As the deoxidizer, it is desirable to use Ca-Ni base alloy (CaNi5 , or the like), Mg-Ni base alloy (Mg2 Ni, or the like), La (or Ce)-Ni base alloy (LaNi, CeNi or the like). Further, the additional quntity of the deoxidizer is made to about 1-3 times of the reduction equivalent of oxygen contained in the vanadium base alloy raw material, and the melting is executed under inert gas atmosphere or vacuum condition by using an arc melting furnace. By this method, in the melting process, the oxygen contained in the vanadium base alloy raw material is reacted with the deoxidizer and discharged to out of the alloy system as the oxide.

Abstract: PURPOSE:To prevent the erroneous setting of a mode by making the feeling of click different between a 1st photographing mode and a 2nd photographing mode. CONSTITUTION:A click spring 60 is fixed at the shaft end of the rotary shaft 21 of a dial main body 20.

In a 1st exposing mode, the small-diameter projection 30a of a display plate receiver 30 and the small-diameter recessed part 41a of a display plate 40 fall in with the feeling of click a little, and in a 2nd exposing mode, the feeling of click is not obtained because the projection 30a abuts on the plane part of the display plate. Since a clear difference lies between the 1st and the 2nd exposing modes, there is no fear that a mistake is made.
