Abstract: PURPOSE:To easily synchronize a complicated three-dimensional picture and a two-dimensional picture on the real-time basis and to mix-display the synthesized picture on a CRT by outputting a hidden-surface processing result through a frame memory having double-buffer composition. CONSTITUTION:Tree-dimensional picture data prepared by a hidden-surface processor 11 are inputted to a first (second) frame memory 9 (10), and the three- dimensional picture data are outputted from a second (first) frame memory 10 (9) and inputted to one side of a synthesizing circuit 8. Thereafter, when two-dimensional picture data are outputted from a third frame memory 5 and inputted to the other side of the synchronizing circuit 8, the three-dimensional picture and the two-dimensional picture can be displayed in a mixed state. Thus, the two-dimensional picture data and the three-dimensional picture data can be synthesized and displayed easily without limiting the number of the pieces of polygon information for one picture, which become the original of three-dimensional picture data.

Title: Frequency variable lc resonance circuit
Inventor: KOGA YASUHIRO
IPC: H01F29/12
Filed: 1987-12-28
Abstract: PURPOSE:To obtain a constant power pass band width even when the resonance center frequency is changed by using two or more types of materials with different permeability as a core varying the inductance of a variable coil. CONSTITUTION:The resonance circuit consists of the variable coil 1 and a capacitor 2. As the variable coil 1, two or more types of materials with different permeability such as brass and ferrite are in close contact to constitute the core for the variable coil. The sharpness Q of the resonance when a brass is put in the coil to increase the resonance frequency is made higher than the Q when the resonance frequency f0 is decreased with the ferrite in the coil. That is, the core material is selected so that the relation of (resonance frequency f0)/(sharpness Q of resonance) is always made constant. Thus, even when the resonance center frequency is changed, the power transmission band width is made nearly constant.
