Fused pyridazine derivatives represented by formula (I) or pharmaceutically acceptable salts thereof (wherein each symbol has the meaning as defined in the specification.). Because of inhibiting poly(ADP-ribose)polymerase, the compounds represented by formula (I) are useful as preventives and/or remedies for various ischemic diseases (in brain, cord, heart, digestive tract, skeletal muscle, retina, etc.), inflammatory diseases (inflammatory bowel disease, multiple cerebrosclerosis, arthritis, etc.), neurodegenerative diseases (extrapyramidal disorder, Alzheimer's disease, muscular dystrophy, lumbar spinal canal stenosis, etc.), diabetes, shock, head trauma, renal failure, hyperalgesia, etc. Moreover, these compounds are useful as agents against retroviruses (HIV etc.), sensitizers in treating cancer and immunosuppressants.

A display device is provided with a shift register having a plurality of bistable circuits, each of the bistable circuits being connected to a corresponding scanning line. An RS flip-flop circuit provided in each of the bistable circuits functions as a memory portion for discriminating a start position of a display region for partial display. When partial display is carried out, first, only the RS flip-flop circuit corresponding to the start position of the display region is put into the set state, that is, only the bistable circuit corresponding to the start position of the display region is put into the set state. Moreover, the scanning lines that are connected to the bistable circuits from the start position to the end position are driven sequentially. During this, only the bistable circuit corresponding to the start position is kept in the set state, and the other bistable circuits are kept in the reset state.

A noise suppression device calculates a subband SN ratio calculation based on a noise likeness signal, an input signal spectrum and a subband-based estimated noise spectrum. The device calculates a subband-based input signal average spectrum, calculates a subband-based mixture ratio of the subband-based estimated noise spectrum to the subband-based input signal average spectrum on the basis of the noise likeness signal, and calculates the subband-based SN ratio on the basis of the subband-based estimated noise spectrum, the subband-based input signal average spectrum and the mixture ratio.

A game machine has an LCD, a cross key, and a memory. The memory stores a plurality of words and a plurality of translations each corresponding to the plurality of words. A computer of the game machine displays at least one of the plurality of words on the LCD, and updatedly displays on the LCD a word which is being displayed on the LCD by being changed to another word in response to an operation of a certain push portion of a cross key. The translation of the word which is thus being displayed on the LCD is updatedly displayed in place of the word during a period from accepting an operation of another push portion of the cross key to cancelling the operation, and when the operation is cancelled, the word which was displayed on the LCD before the operation is displayed in place of the translation which is being displayed on the LCD.

The invention relates to a zoom lens wherein the total of lens components is reduced as much as possible and image-formation capability is enhanced far more stably over the entire zoom range, so that a lot more thickness reductions are achievable upon received at a lens mount, and an electronic imaging system that incorporates it. The electronic imaging system of the invention comprises a zoom lens having a plurality of lens groups G1 and G2 with a variable space between adjacent lens groups during zooming or focusing, wherein the lens group G1 nearest to the object side of the zoom lens comprises two components consisting of a negative lens component and a positive lens component, each having an aspheric surface, and an electronic image pickup device located on an image side of the zoom lens. Image data obtained by taking an image is processed to produce image data with shape changes as an output. The zoom lens satisfies condition (1) that defines the degree of barrel distortion at a zoom wide-angle end.

An echo canceller has a high-pass filter 11, a speaker 3, an A/D converter 6, and an echo canceller 7. The high-pass filter 11 suppresses a low-frequency component in a received signal. The speaker 3 outputs an acoustic sound of a low-frequency suppressed received signal passed through the high-pass filter 11. The A/D converter 6 converts an acoustic echo from a microphone 4 into a transmission signal of a digital form. The echo canceller 7 generates a pseudo echo signal based on the low-frequency suppressed received signal passed through the high-pass filter 11, and eliminates the acoustic echo to be inputted to the microphone 4 from the speaker 3 by subtracting the pseudo echo signal from the digital signal converted by the A/D converter 6.
摘要:
A hydrodesulfurization catalyst used for hydrodesulfurization of catalytically cracked gasoline comprises a support composed mainly of alumina modified with an oxide of at least one metal selected from the group consisting of iron, chromium, cobalt, nickel, copper, zinc, yttrium, scandium and lanthanoid-based metals, with at least one metal selected from the group consisting of Group 6A and Group 8 metals loaded as an active metal on the support. Hydrogenation of olefins generated as by-products during hydrodesulfurization of the catalytically cracked gasoline fraction, as an important constituent base of gasoline, can be adequately inhibited to maintain the octane number, while sufficiently reducing the sulfur content of the hydrodesulfurized catalytically cracked gasoline fraction.
