A gate electrode 11 composed of poly silicon is formed in a channel part on a gate insulating film 61. Said electrode 11 is used as a mask, and a source region 21 and a drain region 22 are formed by implanting B<+> ions. After a thin film transistor is manufactured, carriers of the same polarity as the majority carrier in the regions 21, 22 are injected into the interface level of the insulating films 61A and 61B by using tunnel effect, hot electron effect, etc. Thereby the threshold value Vth of the thin film transistor is shifted to the high voltage side.

Title: Signal recording method
Inventor: ENDOU KIYONOBU
IPC: G11B7/0045
Filed: 1984-03-30
Abstract: PURPOSE:To record signals in the best condition at all times with control by recording and reproducing signals with variation of the recording beam intensity and then deciding the optimum value to obtain the best condition of the reproduced signal. CONSTITUTION:A test pattern waveform is sent from a signal source 31 at the beginning of signal recording, and at the same time the amplification degree of an amplifier 32 is gradually changed. Thus the waveheight value, i.e., the P-P value is varied for the electric signal sent to a light modulator 25. Based on the P-P value, the signals are recorded in a recording medium 30 with different levels of depth at a hollow part. When the maximum P-P value is obtained for the reproduced waveform obtained from a photodetector 45, the P-P value of a signal waveform obtained from a photodetector 36 corresponding to the detector 45 is measured by a P-P value measuring electric system 37. This measured P-P value is stored in a memory 48 as the optimum value. Under such conditions, the signal recording is started. Then the P-P value of the signal waveform obtained from a photodetector 36 is compared with the P-P value stored in the memory 48 by a comparison electric system 49. Thus the signal can always be recorded under the optimum conditions.

Abstract: PURPOSE:To make judgement as to whether a series of image formation processes under way is feasible or not by computing the number of sheets stacked in a stacking unit via a control part through the comparison of signals detected by and sent from the first and second sensing means. CONSTITUTION:Sheets 'S' are detected by a sheet feed sensor 9 and a signal detected thereby is transmitted to CPU 29. And CPU 29 counts the number of the sheets 'S' on the basis of the signal detected by the sheet feed sensor 9 and saves the counted number in RAM 30. Then, CPU 29 makes a comparison between the number of the sheets 'S' counted via the detected signal of another sheet feed sensor 5 and that counted via the detected signal of the sheet feed sensor 9, thereby calculating the number of the sheets 'S' remaining on a stack tray 6. The sheets 'S' are fed in a sequence from the stack tray 6 and when a remnant on the tray 6 has reached the predetermined number set up by an input part 31 and saved in RAM 30, a control part 27 feeds the predetermined number of the sheets 'S' from a sheet feed tray 2 to the stack tray 6.

Abstract: PURPOSE:To prevent the density of conc. sulfuric acid from changing by immersing a treated substrate in hot sulfuric acid made bubbling by gas containing ozone. CONSTITUTION:O2 which is excited by an oxone generator 6 and contains O3 is spouted out from gas spouting nozzles 4 via a quartz air transmission tube 5 into conc. H2SO42 heated in a quartz vessel 3 and makes the H2SO42 bubbling. By this operation, O3 contained in O2 reacts upon H2SO42 and H2SO3 and O are produced in H2SO4. Then, for instance treated substrates 8 which are coated by resistor layers and are arranged on a substrate holder 9 are immersed in this H2SO4 2 and the resistor layers are oxidized by H2SO3 and O and solved by hot H2SO4 and removed from the substrates 8. This method can also be applied to removing inorganic contaminant formed in such a case as the resistor is made ash.

Filed: 1993-03-24
Abstract: PURPOSE:To measure the inspected surface and the outside diameter displacement without turning a lens after the alignment of the inspected lens by turning the nonspherical lens nearly around an optical axis and allowing a rotary shaft and the optical axis of the inspected lens to coincide through the autocollimation method. CONSTITUTION:A holding means 2 holds the spherical surface side of an inspected lens 1 by the air suction. When the cross point between a rotary shaft 3 and a detection surface 12 is set at O2, and the cross point between an optical axis 14 and the detection surface 12 ms set at P, the angle formed between the segment O2 and an x-axis shows the direction of deflection. The revolution angle in the case where the inspected lens 1 is turned and the P point is superposed on the x-axis is read out from an angle sensor 4, and then the value (beta) is obtained. Accordingly, obtaining the deflection and direction of the rotary shaft 3 and the optical axis 14, the inspected lens 1 is shifted on the holding means 2, and the rotary shaft 3 and the optical axis 14 are allowed to coincide. After the alignment of the inspected lens 1 is performed. the signal showing the shape displacement is received from each displacement meter 13 without turning the inspected lens 1.

IPC: F02M51/08
Filed: 1987-03-23
Abstract: PURPOSE:To effectively eliminate air bubbles left behind in the inner part of a fuel injection valve at time of a hot start, by making a sufficient pressure differential so as to be secured between a fuel feeding port and a fuel return port. CONSTITUTION:Owing to the pressure of a partition device 23, a fuel supply system passage at time of operation of a fuel injection valve is constituted of an empty space 16a in a passage space 16. On the other hand, a fuel return system passage is constituted of only one system of fuel return passages 1 and 19 and empty space 16b, whereby such a possibility that a fuel feeding port 4 and a fuel return port 15 are interconnected to each other via the space 16 will never happen. Consequently, if partitioning action of the partition device 23 and an area of the fuel supply system passage are made sufficiently larger than that of the fuel return system passage, fuel pressure at the side of the fuel feeding port 14 comes high, so that a sufficient pressure differential is securable.

Title: Method for estimating two-dimensional data from observed data
Inventor: TAKEGAWA NAOKI
IPC: H04N19/423
Filed: 1993-03-24
Abstract: PURPOSE:To estimate a stable and accurate solution with a less arithmetic quantity by decreasing the resolution of processing in an area, where the distribution of the solution is large, and increasing the resolution in an area, where the distribution is small, by controlling the resolution from the estimated error of the solution. CONSTITUTION:An evaluated value arithmetic circuit 6 calculates an evaluated value from the observed data, variance value and estimated solution vector value. When the evaluated value is smaller than a threshold value, the evaluated value of the variance value of the solution is reduced and outputted to a resolution deciding circuit 3. When the evaluated value is not reduced even by reducing the variance value of the solution, a select signal is outputted to a solution vector output circuit 7. The circuit 7 inputs a solution vector and outputs the solution vector as the final arithmetic result through a solution vector output terminal 10 corresponding to the select signal from the circuit 6. At the time of arithmetic start, an initial vector is inputted from an initial solution vector input terminal 8 and written through a switch 9 to a solution vector memory 4. Thus, the high-accuracy solution vector is provided with the less arithmetic quantity adaptively to the local character of observation noise.
