A digital attenuator is disclosed which is capable of having the output PCM signal attenuated nearly in proportion to the input PCM signal level based upon simple logic operations ofP.sub.out = .alpha. P.sub.in + NwhereP.sub.out = output PCM signalP.sub.in = input PCM signal processed by a compressor.alpha. = a real number satisfying the condition 0 O, to obtain the sum .alpha.P.sub.in + N, the output signal .alpha.P.sub.in, which is obtained in the manner described above, is added to a specific pattern representing N which is generated by a specific pattern generating circuit. The above sum is compared with P.sub.in and when the former is larger than or equal to the latter, P.sub.in becomes P.sub.out, while when the former is less than the latter, the sum is derived as P.sub.out. Thus, an attenuation nearly proportional to the input FCM signal level may be attained.
摘要:
An image forming system, comprises an image forming apparatus including a first memory section to store a program to conduct a predetermined operation, and an image forming apparatus connecting section to connect the image forming apparatus with a network; and an administrating apparatus including an administrating memory section to store a rewrite program for the image forming apparatus, and an administrating apparatus connecting section to connect the administrating apparatus with the network. The image forming apparatus accesses the administrating apparatus through the network, obtains the rewrite program stored in the administrating memory section, and rewrites the program stored in the first memory section with the obtained rewrite program.

摘要:
This invention relates to a triazolyl alcohol derivative having an optical activity of (-) or (+) and represented by the general formula (I), ##STR1## wherein X represents a hydrogen atom or a chlorine atom and the asterisk indicates an asymmetric carbon atom, a process for preparing same, and a fungicide containing same as active ingredient.
摘要:
A fibrous activated carbon with a metal chelate compound supported thereon which is suitable for removal of toxic substances in gas. This activated carbon is obtained by attaching a solution or dispersion of the metal chelate compound onto the fibrous activated carbon followed by drying. Contacting the activated carbon with a toxic substance-containing gas provides very efficient removal of the toxic substance from the gas.
摘要:
A tongs apparatus includes an upper frame suspended from a crane, a pair of first arms journaled on the upper frame, a pair of second arms journaled on the first arms and disposed to cross each other, and a supplemental-holding-force apparatus. The supplemental-holding-force apparatus comprises a chain motor; a chain wound and unwound by the chain motor; a ring-shaped member connected to the chain and having an elongated hole; and a lifting metal fitting having a guide pin slidably engaged with the ring-shaped member. The chain is wound or unwound by the chain motor in order to move the ring-shaped member vertically to thereby supplement a holding force generated through closing of the second arms.
摘要:
A display control device includes a display panel for displaying data containing textual and/or drawing data, a display buffer for storing data to be displayed on the display panel, a display control section for controlling display of the display panel, a backlight for illuminating the display panel, an illumination instruction section for outputting a backlight illumination instruction, and an illumination control section for controlling the illumination of the backlight according to the backlight illumination instruction from the illumination instruction section. The display control section changes a display configuration of the data to be displayed on the display panel when the illumination instruction section outputs the backlight illumination instruction.
