Title: Method and apparatus for picture processing and transmission
Inventor: NUMAKURA TAKASHI
IPC: H04N1/407
Filed: 1990-05-07
Abstract: PURPOSE:To improve the reproducibility of density and gradation by acquiring a picture information of an original picture to be copied being a true object and processing the picture information with a specific gradation conversion equation so as to obtain gradation intensity. CONSTITUTION:A sender side equipment A reads an original picture with a detector 2 by photoelectric scanning or the like and a correction processing section 3 applies required processing such as shading correction. Then a gradation adjustment section 4 decides an area ratio of a picture element recorded on a recording sheet corresponding to the density of an original picture according to (gradation conversion equation I). Moreover, a compression section 5 applies compression processing to picture information to eliminate the redundancy of the picture information in the case of sending a picture information signal obtained by the gradation adjustment section 4. Then a modulation section 6 modulates the on the other hand, into a carrier signal and the signal is sent through a line or a data network or the like. In the gradation conversion equation I, x is a basic luminous quaintly, y is a gradation intensity set to a picture element on a copied picture corresponding to an optional picture element on an original picture, yH and yS are preset gradation intensity values at brightest and darkest parts on the original picture, alpha is a surface reflectance of a copied medium, betais a numeral decided by beta=10<-gamma> and k, gamma are constants.

Title: Test device of semiconductor memory
Inventor: TAKANO SATOSHI
IPC: G11C29/00
Filed: 1982-07-02
Abstract: PURPOSE:To make it possible to test a semiconductor memory in the nibble mode, by providing a means which compares and discriminates contents of the first register, where the output from a high-speed buffer memory is stored, with those of the second register where reference data from a pattern generator is stored. CONSTITUTION:In the read operation of the nibble mode, data read out from a dynamic RAM 1 is transferred to the first register 8 through a very high-speed ECLRAM 7. Reference data 5 from a pattern generator 2 is transferred to the second register 9. These data are transferred to comparators 10a-10b simultaneously and are compared with each other, and a high level is outputted to an AND gate 11 if they coincide with each other, but a low level is outputted, if dissident, there. Thus, contents of defective bits are detected easily by checking the output of the gate 11. Output data in the nibble mode is compared and dis- criminated surely for high speed data transfer.

Title: Continuous rolling control method
Inventor: TERASAKI TADAO
IPC: B21B37/18
Filed: 1986-05-22
Abstract: PURPOSE:To eliminate thickness variation and to improve the product yield by reducing a change roll draft to the limit, compensating the reduction with increased drafts of other stands, quickly opening the change roll, and controlling a roll gap and speed of preceding rolls. CONSTITUTION:In the case that the roll of the 5th stand, for example, in sheet stock continuous rolling stands 1-6 is changed, the draft of the 5th stand is reduced to the limit draft generating no slip and the reduction is compensated with increases in the draft and speed adjustment of stands 1-4 except the final stand 6. The stand 5 changing rolls is quickly opened and the gap and speed of the preceding stands 1-4 are controlled. That operation prevents generation of slip flaws, makes thickness variation time a moment or very short, and improves the product quality. If the stand 5 is quickly opened at weld parts of the sheet stock, those parts are cut and discharged later, so that all product thickness variations are eliminated.

Filed: 1985-05-29
Abstract: PURPOSE:To obtain an accurate focus error signal by providing a compensating means which nearly eliminates at least a coma aberration other than the astigmatism of (-1)-order diffracted light that a photodetecting element photodetects to a diffracting means or between the diffracting means and photodetecting element CONSTITUTION:Reflected light 8 which is reflected by a disk 4 and made incident on an objective 3 is further made incident on a phase type diffracting plate 2, which diffracts the light again into (+1)-order diffracted light and (-1)-order diffracted light. The (+1)-order diffracted light [or (-1)-order diffracted light] which has almost no aberration is returned to a light source 1 and the (-1)-order [or (+1)-order diffracted light] 9 which has astigmatism illuminates the photodetecting element 5. Further, the angle of divergence of the (+ or -1)-order diffracted light of the phase type diffracting plate 2 is so set as to obtain enough astigmatism for focus servocontrol. Consequently, the device is reduced in size and the quantity of astigmatism is increased, so that an accurate, high-sensitivity focus sevocontrol signal is obtained.
