Abstract: PROBLEM TO BE SOLVED: To prevent the sudden degradation in a contrast at the time of high- duty driving by decreasing transverse streaks and unequal displays of animation images. SOLUTION: An FLS driving method is used and the cyclic functions which are subjected to column permutation and column code inversion are used as scanning functions. Further, frame frequencies are doubled. The cyclic functions below the degree 512 which are subjected to the column permutation and the column code inversion are used as the scanning functions in the case of 300 pieces of the scanning lines. The cyclic functions below the degree 512 which are subjected to the column permutation and the column code inversion are used as the scanning functions in the case of 384 pieces of the scanning lines. An MLS driving method is otherwise used and the cyclic functions which are subjected to the column permutation and the column code inversion then to Kronecker product extension are used as the scanning functions.  The FLS driving method is otherwise used and the cyclic functions which are subjected to the column permutation and the column code inversion then to row permutation so as to part the adjacent rows are used as the scanning lines.

IPC: H03F3/08
Filed: 1992-10-28
Abstract: PURPOSE:To reduce output current error caused by input offset by interposing a current mirror circuit in an input current. CONSTITUTION:Input currents to terminals 1 and 2 are respectively inputted to the collectors of transistors Q11 and Q14. The currents to flow to the collector of a transistor Q13 at a first current amplifier part and to flow to the collector of a transistor Q16 at a second current amplifier part are compared with a current source Icon by interposing a current mirror circuit 3 and negatively fed back through a transistor Q17 to transistors Q12, Q13, Q15 and Q16 until the same current value is provided. The value of a voltage source V1 is set so that the current source Icon can not be turned to a saturated state. Therefore, the voltage source is turned to an output current keeping Icon/(Iin1+ Iin2) to the input current, a buffer amplifier is unnecessitated, error is not added to the output current affected by the characteristic of the buffer amplifier and even when the input current is made maximum, the error of the output current is eliminated.

Title: Infared imaging system
Inventor: TOMOYASU KUNIHIRO
IPC: G01J1/02
Filed: 1992-10-29
Abstract: PURPOSE:To obtain a clear image under a low temperature environment while eliminating useless power consumption under a high temperature environment by providing an element temperature setting circuit and a refrigerator drive control circuit. CONSTITUTION:A refrigerator drive control circuit 13 controls power supply to a refrigerator 8 while receiving an element temperature signal from an element temperature sensor 7 so that an infrared detecting element 1 has a cooling temperature being set by an element temperature setting circuit 17. Since the element 1 is set at a high cooling temperature under a high temperature environment where infrared ray detection signal of the element 1 has a high level, even a relatively high thermal noise level has no affect on infrared detection. Consequently, useless power consumption where the element 1 is set at a high cooling temperature and the refrigerator 8 cools the element 1 down to a low temperature can be eliminated. On the contrary, under a low temperature environment where the element 1 has low infrared ray detection signal level with respect to thermal noise level, a clear image can be obtained by setting the element 1 at a low cooling temperature thereby lowering thermal noise level.

Abstract: PURPOSE:To compensate surely deflection distortions, by interrupting pattern drawing when deflection distortions can not be sufficiently compensated on account of position compensation of main deflection for the movement compensation of a sample stand, and resetting the compensation data of sub-deflection distortion. CONSTITUTION:If a sample stand 12 moves over the set value of transfer which is previously stored on a transfer quantity register 57 during pattern drawing in a sub-field, a control signal is delivered from a comparator 58 to a deflection controller 51 for pattern drawing data, and pattern drawing is interrupted. Distortion information of main deflection corresponding to the position is reset, and a DAC 55 for transfer compensation of a sample stand is also reset against a main deflection DAC 53 to continue the interrupted pattern drawing of a small region. Thus, distortion information of deflection is sequentially renewed, so that the pattern drawing of high accuracy can be realized. Therefore, while moving continuously the sample stand 12, pattern drawing can be executed utilizing a two-stage deflection including large and small deflections.

Abstract: PURPOSE:To restore an original copy from a marked copy, as it is, by generating mask data for masking a color image which is judged to be a region specified color on the copy by a judging means in response to a copy mode given by a mode indicating means. CONSTITUTION:When a copy mode is given by an operating section, a mask processing section 40 generates mask data for masking a color image which is judged to be a region specified color on a copy by a color judging circuit 37 as a judging means in response to the copy mode, and outputs it to an erase unit to erase the latent image of the color image which is judged to be the region specified color on the copy formed on a photosensitive drum. An image in a region which is judged to be the region specified color on the copy by the color judging circuit 37 is developed in the region specified color and restored in monocolor by a developing unit. In addition, the image in the region which is judged to be the region specified color on the copy by the color judging circuit 37 is developed in the region specified color and restored in black by a developer. It is thus possible to easily restore an original copy from the copy marked by a marker.
