Title: Digital signal processing unit
Inventor: IWAHASHI NAOTO
IPC: H03M7/38
Filed: 1988-02-29
Abstract: PURPOSE:To approach the shape of spectrum of quantized noise to the spectrum shape of an audio signal by weighting an output signal of an inverse requantizer and an input signal to a requantizer respectively and outputting the result to a prediction filter. CONSTITUTION:A subtractor 51 is used to obtain a quantization error signal SE1 being a difference between an input signal to a requantizer 21 and an output signal of an inverse requantizer 22. Moreover, after the quantization error signal SE1 is weighted by gamma(0<gamma<1) via a multiplier 52, the result is added to the input signal of the requantizer 21 via the multiplier 53 and fed back to the adder 23 and the prediction filter 24. Thus, the spectrum shape LNS of the requantizer noise is made close to the spectrum shape LSS of the audio signal in response to the weight coefficient gamma to obtain a function of noise shaping, then the signal versus quantization noise ratio (SNR) in the listening sense is improved by utilizing the masking effect.

Title: Thermal transfer printer
Inventor: HORI YASURO
IPC: H04N1/23
Filed: 1985-03-11
Abstract: PURPOSE:To enable to print with favorable quality even on a recording paper poor in surface smoothness, by a method wherein a pressure with which a thermal head is pressed against a platen is varied with time, printing is conducted when the pressure is increased, and a paper is fed when the pressure is decreased. CONSTITUTION:The pressure P with which thermal head 2 is pressed against the platen is varied on a dot basis or a line basis by a mechanism provided for this purpose, and printing is conducted by passing an electric current to the head 2 when the pressure P is higher than an average pressure PA, while paper feeding is conducted when the pressure P is loser than the average pressure PA. Namely, the pressure P is varied in a sine wave form, and printing is conducted by passing an electric current to the head 2 when the pressure P is lower than the average pressure PA. On the other hand, the relative velocity of the head and the paper is set to be 0 when the pressure P is muximum and be maximum when the pressure P is minimum. For example, a signal from a timing-generating circuit 7 for a vibration controller 6 is supplied to an inertial force vibrator 5, which generates a vibrating force to vibrate the head 2. Since a fixed pressure is exerted by a spring 4, a pressure varied as shown can be obtained by the vibration. In this case, the timing generated by the circuit 7 and the timing of a driving signal supplied to a paper-feeding mechanism are so selected as to obtain the phase relationship as shown.

Filed: 1981-03-30
Abstract: PURPOSE:To correct the shift in forcus due to transmitted light wave length of an optical lens system, by using a filter having different thickness according to the transmitted wave length used for an optical reader. CONSTITUTION:A reflected light 8 reflected from a paper 6 is collected with a lens system 7 via a filter 3 and made incident to a photodetector 8, and an image on the said paper 6 is formed. Since described information by various methods such as pencil, ball-point pen, and print ink and the like exists on the paper 6, filters 2, 3- are used with switching by means of switching mechanism 1, 4, 5 to detect required information out of the pictures, allowing to limit the reading wave length. Although the refractive index of the lens system 7 is different depending on the wave length, the focus of the lens system 7 can approximately be made constant by suitably selecting the thickness of the filters 2, 3-. Thus, even when various filters are switchingly used, since the focus can always be made constant, a sharp image can be formed on the photodetector section.
