Title: Beam index type color television picture receiver
Inventor: ISOWA HIDEHIKO
IPC: H04N9/24
Filed: 1978-11-21
Abstract: PURPOSE: To improve the linearity of the horizontal deflection and thus to eliminate the color shift by supplying the output current of the LPF of the PLL circuit to the primary side of the control transformer and then giving the negative feedback type control to the horizontal deflection current.  
     CONSTITUTION: Photo detector 21 is provided outside picture tube 10, and the output signal is supplied to BPF22 for extraction of the index signal. And the index  signal is supplied to PLL30. And now if the horizontal scanning speed is decreased  with lowering of the frequency of the index signal, output voltage EL of LPF34 in  circuit 30 lowers down with voltage EC increased to be applied to primary side 51 of  control transformer 50. And the inductance decreases at secondary side 52, and the  current flowing to horizontal deflecting coil 61 increases along with the horizontal  scanning speed increased. On the contrary, if the horizontal scanning speed increased, the speed is retarded. Thus the linearity of the horizontal deflection is improved with the negative feedback type control, and as a result the horizontal scanning speed becomes virtually constant for the horizontal beam of the electron beam.

Title: Wafere polishing method and wafer polishing base plate used for it
Inventor: MATSUSHITA HIROYUKI
IPC: B24B7/10
Filed: 1986-06-23
Abstract: PURPOSE:To make the polishing rate in a wafer face uniform and obtain a wafer with high flatness by polishing a wafer by the use of a polishing base plate in which the rigidity of the wafer installing part is concentrically and continuously varied from the center toward the outer periphery of said installing part. CONSTITUTION:A stainless disk 12 is installed on a wafer installing part and a hard rubber sheet 10 and a template 11 are stuck on it, and a wafer 3 is fixed to the inside by means of the surface tension of water. And, as the wafer 3 is pressed against a polishing cloth 6, since the rigidity of the installing part is shifted from the center part to the outer periphery, the wafer 3 is slightly deformed and the distribution of contact pressure is the largest at the center part gradually becoming smaller toward the outer periphery, and a polishing rate is the largest at the center gradually becoming lower toward the outer periphery. On the other hand, the wafer 3 is polished in a condition that it is sunk into the elastic polishing cloth 6, and a contacting condition and the feeding condition of a polishing liquid are different between the center part and the periphery part, causing the polishing rate to be larger on the periphery part. And, by combining these two phenomena, the polishing rate in the wafer 3 can be made uniform, obtaining a wafer 3 with high flatness.
