Title: Crt control circuit and receiver
Inventor: NAGATA KEIICHI
IPC: G09G1/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To correct the distortion of a point form and to obtain a uniform focus without raising luminance at the peripheral part of a CRT screen by applying voltage signals mutually different in parabolic waveforms by which a voltage value is higher in the peripheral part than the center part of the CRT screen. SOLUTION: A first grid voltage application circuit applies the voltage signals of the different parabolic waveform by which the voltage value is lower in the peripheral part than the center part of the CRT 5 screen to the first grid G1. Second grid and third grid voltage application circuits apply the voltage signals of the different parabolic waveforms by which the voltage values are higher in the peripheral part than the center part of the CRT 5 screen to a second grid G2 and a third grid G3. Thus, not only the voltage signal of the parabolic waveform by which the voltage value is higher in the peripheral part than the center part of the CRT 5 screen but also the voltage signal of the parabolic waveform by which the voltage value is lower in the peripheral part are applied to electronic beams. Thus, the uniform focus can be obtained since the adjusting possible range of the voltage condition added to the electronic beams extends.

Title: Manufacture of semiconductor device
Inventor: KUWAGATA MASAHIRO
IPC: H01L29/78
Filed: 1981-10-09
Abstract: PURPOSE:To provide a manufacturing method for a semiconductor device capable of forming a drain diffused region in which deterioration in the characteristics of a punch- through voltage hardly occur for micronimiaturization of the size of a field effect transistor. CONSTITUTION:An N<+> type diffused impurity is adhered to the part 2 of the source region of the hole formed at an insulating film 4 formed on a P type silicon substrate 1. Thereafter, a hole is opened at the film 4 on the part to become a drain ragion 3, and P type and N type impurity source 10 are adhered. Then, when the substrate 1 is diffused under the adequate conditions, an N<+> type diffused region 2 is formed as a source region, an N<+> type diffuse region 3 is formed as a drain region, and a P<+> type diffused ragion 11 to surround the region 3 is formed. In this case, since the boron impurity density is selected to be smaller than that of the boron, the inside diffused layer becomes N<+> type region, and the P<+> type diffused region is formed to surround the inside layer. The thickness of the depletion layer of the drain region is determined by the density of the region having smaller density and hence the region 11. Since the region 11 has large impurity density higher than the region 11, the thickness of the depletion layer becomes small, with the result that a punch-through phenomenon hardly  occur.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy for positioning the forward end of a probe with respect to a circuit pattern formed on a board. SOLUTION: The function tester tests the function of a board 8 on which a circuit pattern is formed. A recognition mark for alignment is put on a probe plate 15 having a probe touching the board 8 and the circuit pattern formed thereon and read out by means of a single camera through an optical system 21. An image thus read out is then processed and the position of the board 8 or the probe plate 15 is corrected relatively to correct the shaft of the alignment mark. Since the alignment of the circuit pattern on the board 8 and the probe is performed optically, the accuracy is enhanced significantly and the requirements of fine patterning and high density can be satisfied while enhancing the reliability of test.
