Title: Linearizer
Inventor: TANABE SHINJI
IPC: H03F1/32
Filed: 1983-07-13
Abstract: PURPOSE:To improve the ratio of desired wave to undesired wave D/U of an output by connecting a filter eliminating the 2nd harmonic to an output of a distortion generator generating ternary distortion so as to improve the cross modulation distortion. CONSTITUTION:A filter 12 used for a linearizer 6' is to eliminate the 2nd harmonic generated in the distortion generator 9 and a low-pass filter, a band stop filter and a band-pass filter are used. Since an intermediate frequency is <=1/10 in comparison with a transmission frequency in general, it is easy to eliminate the 2nd harmonic at the intermediate frequency band from the relation of a specific band thereby attenuating the harmonic largely. In this invention, since the 2nd harmonic produced at an intermediate frequency amplifier is not eliminated by a band-pass filter in the transmission frequency band and a filter eliminating the 2nd harmonic at an output of a distortion generator 9 included in the linearizer is provided, the 2nd harmonic is eliminated easily thereby improving the D/U of the transmitter.

Title: Method and device for encoding processing
Inventor: OCHI HIROSHI
IPC: H04N19/00
Filed: 1986-06-02
Abstract: PURPOSE:To encode images with high efficiency by changing the arrangement of an image signal not in an area where density variation is large, but in an area where density variation is small. CONSTITUTION:A comparator 11 compares individual image signal levels with the output of a threshold memory 14 to output signals of high level (1) and low level (0) according to whether the image signal levels are larger or smaller, and the output signals are stored in image signal memories 12 and 13. At this same time, a maximum and minimum detecting circuit 15 finds the maximum value Lmax and the minimum value Lmin from tie image signal levels in each block and further calculates their difference LD=Lmax-Lmin. When the value LD is larger, large variation in image signal level, i.e. density on an original is indicated when the Ld is smaller, no variation in the density on the original is indicated. Therefore, when the value LD is larger, the image signals are not rearranged and only when the LD is smaller, the image signals are rearranged. Consequently, isolated signals of black are reduced and high encoding efficiency is obtained.

Title: Dehydrating machine
Inventor: MAKINO YOSHIYUKI
IPC: D06F49/00
Filed: 1989-05-22
Abstract: PURPOSE:To prevent the generation of abnormal sounds, damage of dehydrated articles and dropping of dehydrated articles into a removed water receiving tank for inspection of an operator by cutting off the supply of current to a dehydrating motor and driving an annunciator when the hydrated articles are detected by a detector device for detecting the presence of the dehydrated article near the upper portion of an opening of a dehydrating tank. CONSTITUTION:When dehydrated articles are received in a dehydrating tank 6 during the dehydrating running, the dehydrated articles may depart from an opening 6a of the dehydrating tank 6. Since then the dehydrated article cuts a light path from a luminescent element 11 to a light receiving element 12, the 'presence' detecting signal is outputted from a detecting device 10 to be given to a microcomputer 24 which interrupts the supply of current to a dehydrating motor 7 and drives an annunciator 27 on the basis of the input of the detecting signal. As a result, the dehydrating running is stopped and an alarming sound is generated from the annunciator 27. Thus, a large abnormal sound caused by the dehydrated article departing from an opening 6a of the dehydrating tank 6 is eliminated, the dehydrated article is not damaged, the dehydrated article is prevented from dropping into a removed water receiving tank 3 and a user can be urged for inspection.

Title: Decarburizing refining method for chromium-containing molten steel
Inventor: HIROTA AKIHITO
IPC: C21C7/04
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of Fe-Si for reduction to be used, at the time of decarburizing refining of Cr-containing molten steel, by charging Fe-Mn in the proper period in which C concentration in the molten steel is in a specific range and reducing Cr oxide. SOLUTION: At the time of applying decarburizing refining to a Cr-containing molten steel, Fe-Mn is thrown in the molten steel in the proper period in which C concentration in the molten steel is in the range of >0.5 to >1.0% by weight, and Cr oxide formed during refining is reduced by Mn in Fe-Mn. By this method, the amount of Fe-Si, usually used for reduction of Cr oxide, to be used can be reduced. The timing of the throwing in of Fe-Mn is limited because Cr oxidation loss becomes increased by the local cooling of the molten steel at the time of charging Fe-Mn when C concentration in the molten steel is lower than 0.5% and, further, the temp. of the molten steel is lowered and the concentration of Cr2 O3 in slag is lowered and, as a result, Cr2 O3 reducing reaction by Mn hardly proceeds when C concentration in the molten steel exceeds 1.0%.
