IPC: G06F11/10
Filed: 1990-07-13
Abstract: PURPOSE:To reduce the number of steps required for calculating the coefficients and the error size of an error location polynomial by calculating the coefficients and the amplitude of each error of the error location polynomial in parallel through the use of (t+1) or 2t multipliers and adders in this error detecting and correcting device correcting (t) errors. CONSTITUTION:The calculation obtaining the coefficients of an error location polynomial is implemented by an arithmetic operation section 108 of three (=t+1) control circuit parallel constitution composed of multipliers and adders, etc., and coefficients alpha<a>, alpha<b> of a quadratic error location polynomial expressed in equations I are obtained in the following procedure in the case of 2(=t) errors correction (number shown in brackets depicts a required step number); (a): parallel calculation (2) numerators of equations   and alpha<a>, (b): calculation of 1/  (1), and (c) parallel calculation (1) of equations alpha<a>, alpha<b>. Thus, the coefficients are obtained in total four steps being a half of the step number required by a single multiplier and a single adder. Similarly, when a four-parallel constitution is adopted for multipliers and adders of the error detecting and correcting device for an RS code having an error correction capability of up to three, the coefficients of a cubic error location polynomial are obtained by 14 steps.

Title: Still picture recorder
Inventor: ITO TAKESHI
IPC: H04N5/907
Filed: 1990-07-13
Abstract: PURPOSE:To eliminate the need for a speed conversion memory by selecting a read speed of a picture data from a picture data storage means storing a picture data by one pattern between a speed in matching with a picture scanning speed and a speed in matching with a recording processing speed. CONSTITUTION:A switch 311 selects a clock 4fsc as a write clock Wck. Thus, an output of an A/D converter circuit 12 is written in a frame memory 14 by using the 4fsc clock. Moreover, a switch 312 selects an output of a switch 313 for a read clock Rck. Thus, a picture data written in the frame memory 14 is read by the 4fsc clock in matching with the picture scanning speed. In this case, a switch 35 selects an output of a D/A converter circuit 15. Thus, a still picture stored in the frame memory 14 is monitored for a prescribed time.

IPC: G06F21/12
Filed: 1982-10-20
Abstract: PURPOSE:To prevent the copying and surreptitious use of a program, by omitting a data part containing the number of a medium storing the program out of a medium format and then loading again the data part for collation when a proper number is used to a processor. CONSTITUTION:When a medium storing a program, e.g., a magnetic disk 6 is forwarded, both ID and data fields of a sector 1 of the 1st track are omitted. While a proper number (2350 in the diagram) is allotted to a processor D for shipment. The disk 6 is loaded to the processor D, and 2350 is written to said data omitted part from a switch 1 via a CPU2 and a disk device 4. The processing is possible only when coincidence is obtained between 2350 of the switch 1 and 2350 of the disk 6 when the program is loaded. Thus, copying of the program from the disk 6 or to use the disk 6 with another processor is made impossible then the foul use of a program is prevented.

Title: Image forming device
Inventor: ISHIDA TOMOHITO
IPC: G03G15/047
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To form a good image without irregularity or fog while suppressing irregular electrification of a photosensitive drum. SOLUTION: The surface of a photosensitive drum 1 is uniformly electrified by applying an electrification bias on an electrification magnetic brush in contact with the photosensitive drum 1. The photosensitive drum 1 consists of a drum base body, a charge producing layer, a charge transfer layer, a charge injection layer, etc., and is electrified by directly injecting charges from the electrification magnetic brush 2 to the charge injection layer. For example, the charge producing layer consists of a phthalocyanine deriv. having strong spectral sensitivity in a longer wavelength region over about 400nm. The charge injection layer is composed of zinc oxide having spectral sensitivity in a shorter wavelength region than 400nm dispersed in a proper binder resin.  By balancing and expressing exposing the drum by a balancing exposing device 8 which emits light in <=400nm wavelength just before or after electrification, the apparent resistance of the charge injection layer is temporarily decreased and irregular electrification in the electrifying process can be prevented.

Filed: 1993-07-27
Abstract: PURPOSE:To attain a stable operation under a low power source voltage by making the output side of a first inverter to be a stable low level and the output side of a second inverter to be a stable high level. CONSTITUTION:When a circuit threshold voltage of an inverter IVM1 is set to be less value than a half value of the power source voltage, a node NDM2 of the outputside goes to a low level by the inversion function of the inverter IVM1 at early time of a data input. The unstable low level is impressed the input terminal of an inverter IVM2, then, an output side, that is a NDM1 goes to almost a high level although it is unstables. At this time, a node NDM2 is pulled-in to the ground level to be a stable low level since transfer gates NTM2, NTM3 are turned ON. This causes the node NDM1 to be held in a stable high level via the inverter IVM2. That is, data levels being pulled-down are compensated with the threshold value voltage of the transfer gate NTM1 and a substrate effect and the nodes NDM1, NDM2 are held stably in the high level and the low level respectively.
