Title: Digital signal receiver
Inventor: MATSUI KAZUNARI
IPC: H04J11/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a digital signal receiver that reduces a load on the hardware by using a decreased sampling frequency and that decreases the number of times of discrete Fourier transform arithmetic operations made. SOLUTION: A down-sample section 21 extracts only the even number order samples of real part data Re, where values are in existence in output data Re, Im from a digital orthogonal demodulation section 14. Since the same data are outputted for a 2-sample period, input number of discrete points 4N is halved into 2N. Then a data interpolation section 22, receiving imaginary part data Im outputs an output signal y(n) consisting of data for odd number order sample periods only by shifting the output signal by one sample period, so that values of the data Im exist for odd order number sample periods the same as the case with the real part signal Re (I). Thus, the input number of discrete points 4N of the output signal y(n) is also halved to 2N. Thus, the number of times of arithmetic operations by a discrete Fourier transform(DFT) section 24 can be reduced.

Title: Information recording medium with built-in cpu
Inventor: HARIMA HIROTSUGU
IPC: G06K19/07
Filed: 1993-04-26
Abstract: PURPOSE:To effectively produce the information media even in a small number of pieces and in various types by recording plural programs in a fixed memory to show the executing procedures of IC cards and also by recording the informa tion in a nonvolatile memory to show the propriety of execution of the cards. CONSTITUTION:A valid instruction table is prepared to show a relevant IC card is executable or not for each of five instructions A-E whose executing routines are prepared in a common RAM. For instance, a valid instruction table (a) included in an EEPROM 15 of a 1st IC card can execute the instructions A, B and E and cannot execute the instructions C and D respectively. Thus, it is enough to prepare a common ROM in the case where the executing routines of instructions A-E are recorded even for production of plural types of IC cards. The 1st IC card is discriminated from a 2nd IC card based on the valid instruction table prepared in the EEPROM 15.

Title: Image forming device
Inventor: KODAMA TAKU
IPC: G03G15/00
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent image quality from being deteriorated by the generation of banding. SOLUTION: A laminated piezoelectric element, for example, is provided on an image forming device main body or at least at one position on a motor, a photoreceptor drum, a paper feed roller, a conveyance roller, a polygon mirror and an exposing element possibly acting as a generating source of banding of an output image. Vibration is controlled by a voltage applied to the piezoelectric element, e.g. random vibration is applied to the image forming device, thus the periodic vibration caused by resonance in the image forming device is suppressed, and an output image having no banding is obtained. Practically, whether power is fed to the image forming device or not is judged (step 1). If no power is fed, a vibrating member waits until power is fed. When power is fed, the vibrating member starts vibration (step 2). Whether a power supply is cut off or not is judged (step 3).  If the power supply is cut off, the routine is returned to step 1. When the power supply is cut off, the operation is completed.
