摘要： An image information transmitting apparatus comprises an image output unit for outputting image information, a modulation unit for pulse-frequency modulating the image information from the image output unit and a demodulation unit for demodulating the modulated signal from the modulation unit to form the image information. The demodulation unit discriminates a signal content by a time interval from a rise to a fall or vice versa of the input modulated signal.

摘要： PURPOSE:To detect micro foreign mater or defects at a high S/N ratio by radiating two light fluxes, which are different from each other in polarization status and wavelength, on the inspection position and generating a heterodyne interference between one light flux in which the polarization status of scattered light changed and the other light flux. CONSTITUTION:A laser beam 12a is led through an optical scanning system consisting of a scanning mirror 13 and an ftheta lens system 14 and then it is divided into a P polarization laser beam 15a and an S polarization laser beam 15b through a polarization beam splitter 15. The beam 15a is set by a filter system 16 in a manner to have an intensity most suitable to the foreign matter inspection and it is converged on an inspection surface 21 by a mirror 18 to form a spot 20. On the other hand, the beam 15b is also converged on the spot 20 on the surface of a face to be inspected 21 by a mirror 19 after passing through a filter system 17. Then, a P-polarized zero-th order diffracted light 23 out of the scattered light, which are directed in a photoelectric detector 29 direction from the spot 20, and a P-polarized element of backscattered light 24 caused by foreign matter or defects generate heterodyne interference because of the alignment of polarization plane, so that only the scattered light caused by the foreign matters or defects can be detected as a beat signal.

摘要： PURPOSE:To eliminate accident such as dropping out of water, in a power source equipment for an aligner by switching power supply from a first power source section to a second power source section upon occurrence of abnormality such as power interruption while simultaneously minimizing the number of object to be fed with power in the aligner. CONSTITUTION:When power is fed normally from an external AC power source, a power source 1 feeds power variously to the entire aligner through a distributing section 5. At this time, a power source 2 is charging an internal battery and not feeding power to the distributing section 5. Upon occurrence of abnormality in the external AC power source, a source monitoring section 3 detects the abnormality quickly and provides a power interruption detecting signal 22. Consequently, the power source 2 feeds power to the distributing section 5 from the internal battery. The distributing section 5 feeds power only to a distribution line 7. By such arrangement, accident due to abnormal power source or damage of wafer can be eliminated.

摘要： PURPOSE:To prevent differential pressure from applying to a beryllium window even though the vacuum break of a port takes place; besides, make this approach keep other exposure devices from being damaged by exchanging abnormal signals regarding an exposure system through communication means which connect mutual control measures. CONSTITUTION:A SOR exposure system is equipped with: a SOR ring as well as a SOR ring control means for controlling the SOR ring; one or more of exposure devices 15 which performs exposure according to a SOR light generated by the SOR ring. In a SOR exposure system where intervals between at least two or more of control means such as the SOR ring as well as exposure device control means are connected by communication means 5, abnormal signals regarding the exposure system are exchanged by the communication means 5. For example, signals which detect the leakage of the vacuum line of the exposure system and output signals generated by the seismometers are used as the abnormal signals. Further, a beryllium window 20 is mounted at a SOR light incident port of the above exposure devices 15 and an emergency cutout valve 21 is disposed at the SOR light incident side in the vicinity of the berylluim window.

摘要： PURPOSE:To provide a regulating method capable of correcting the lateral shear among respective head units, by a method wherein codes for regulating the lateral shear among respective head units are added to data sent from a host computer, which are recognized as data including the codes on the printer side. CONSTITUTION:The data put into respective memories 12A-12D from a host computer 10 are sent to head units 1A-1D corresponding thereto and the recording is carried out by driving respective head units on the basis thereof. When respective color data stored in the data memories 12A-12D are sent to respective head units 1A-1D, the lateral shear among respective head units is corrected by regulating the read position of the data memory. For instance, if the head unit 1B of magenta is laterally lagged by 4 dot contents (lateral shear delta) leftward to a reference position S, though respective data of yellow, cyan, and black are sent out from reference read positions, the color data of magenta is sent out from a position lagged by 4 dots in the DT direction from the reference read position.

摘要： PURPOSE:To obtain a rewritable picture processing circuit of large capacity with a small circuit area and at a low cost, by using a dynamic RAM to a mask table. CONSTITUTION:The masking information is previously stored in a dynamic RAM of a table memory 3. Then the color picture data of (3 X n) bits converted into a parallel form by a data converter 1 is supplied together with the mode signal 6 used as the address signal of the memory 3 (dynamic RAM). For the masking information of the memory 3, the yellow, magenta and cyan masking information are delivered successively synchronously with a clock 5 when the signal 6 of 2 bits is equal to 00, 10 and 10 respectively. Then the dynamic RAM is refreshed by a refresh controller 2 when the signal 6 is equal to 11.

摘要： PURPOSE:To realize a black generation part and a base color removal part with simple constitution by generating four-color print data which includes new black based on three-color data which is dot-expanded based on three-color density data and position information on print dots. CONSTITUTION:When black is generated by superposing three colors one over another while the density of monochromatic black is low, almost the half is residual monochromatic black and the remaining half is replaced with the three- color black to make settings which meet requirements of density and moisture absorption. For the purpose, position information on 4X4 dots consisting one picture element is read by an XCNT 306 and YCNT 307 to determine whether black is generated or not according to the position, thereby performing control as to which part of the 4X4 matrix is made into three-color black. Even when the hue of monochromatic black and the hue of three-color black are different, M, for example, other than K is added during conversion from Y1M1C1 YMCK based on the position information, so that reddish black can be generated.

摘要： PURPOSE:To make the head element structure of upper and lower columns identical to each other by constituting the titled printer such that a shift direction of a data signal of each head element of the upper column and that of the lower column are reversed to each other. CONSTITUTION:The head unit 1 is provided with plural head elements HE1-HE14 arranged in zigzag on upper and lower columns and the elements of an odd number order are arranged to the lower column and those of an even number order are arranged on the upper column respectively. The elements on the upper column are fitted in the normal upper/lower attitude and the elements of the lower column are fitted in the attitude taking upside down together with shift registers SR1, SR3-SR13. Shift registers SR2, SR4-SR14 corresponding to the elements of upper column are connected so that the data signal is inputted from the left sequentially. On the other hand, the shift registers SR1-SR13 of the lower column are connected reversely to the shift direction of the shift registers of upper column.
