IPC: G10L19/038
Filed: 1995-02-24
Abstract: PURPOSE: To obtain the coder for a broad frequency band signal where the signal for a broad frequency band is coded at a low bit rate with high sound quality. CONSTITUTION: A discrimination section 120 obtains a characteristic quantity from an input signal to discriminate the selection of a conversion block length. A conversion circuit 200 converts the signal into a frequency region depending on the block length. A masking threshold level calculation circuit 250 calculates a masking threshold level simulating a masking characteristic of an audible sense for each predetermined period in a block. An inter-block in-block bit allocation circuit 300 uses the masking threshold level to allocate a bit number with respect to the allocated bit number in each block and a predetermined period in the block. A vector quantization circuit 350 selects and uses any of code books 3601 -360N depending on the allocated bit number and applies vector quantization to the converted signal. Furthermore, a gain code book 370 is used to quantize the gain.

Abstract: PURPOSE:To reduce a shift in transfer position regardless of which copying form cassette loading part a form is fed from by driving a timing roller on the basis of timing information corresponding to the copying form cassette loading part. CONSTITUTION:A form 38 fed from an upper cassette abuts on the timing roller 17 gravitationally and by being energized through the rotation of a weight roller 14. When a form 39 is fed from a lower cassette, on the other hand, the form is fed by a lower paper feed roller 15 to abuts on the timing roller 17 and then further feed for a specific time, thereby frming a loop (as shown by an arrow B). The form 38 abuts on the lower roller of the timing roller 17, but the form 39 tends to abut on the intermediate part between the upper roller and lower rollr of the timing roller 17 or the upper roller. In this state, the timing where the timing roller is driven is set selectively to convey a form conveyed from the timingroller to a transfer position (as shown by an arrow A) at the specific timing.

Abstract: PURPOSE: To impart antireflection property and antistatic property to the surface of an optical article by a simple method by forming an antireflection layer comprising a noncrystalline fluorine-contg. polymer on the surface of a body having a specified half-life time of electrification voltage. CONSTITUTION: This product is obtd. by forming an antireflection layer comprising a noncrystalline fluorine-contg. polymer on the surface of a body showing such property that when electrification voltage is applied to the surface and its decay time is measured, the period till the charges become half of initial charges (half-life time of electrification) is <=50sec. Especially, a material having <=20sec half-life time of electrification has a higher effect. When the half-life time for electrification exceeds 50sec, an antistatic property is sometimes not added after the antireflection layer is formed. The material of the article or its surface is not limited, and preferably it is a resin having self-repairing property and scratching resistance. As for the resin having self-repairing property and scratching resistance, a polyurethane resin is most preferable.  The antistatic agent incorporated into this crosslinking-type polyurethane resin, especially a quaternary ammonium salt is preferable.

Abstract: PURPOSE:To easily confirm a communication destination of an original whose transmission is finished by detecting the end of transmission of picture information, reducing the stored picture information in the subscanning direction, and printing out the information onto a transmission result report together with the information relating to the transmission itself. CONSTITUTION:Each picture information on a 1st page and 2nd and succeeding pages of a transmission original is stored in each relevant area of a communication buffer 15 in a facsimile equipment 8, the picture information of the 1st page is read by 16-line each by detecting the end of the original transmission and subject to band expansion and the decoded raster data is inputted to a RAM 26.

The CPU 14 converts the character information relating to the transmission into a raster data together with a routine character string and inputs it to a prescribed address of the RAM 26. Then the data in the RAM 26 is printed out onto a paper sheet 7 via an information print section 22. Thus, the information is printed out on a right half of the paper 7 with reduction as the printed transmission result report and the transmission information is printed out on a left half.
