Title: Two-dimensional method and device for discrete cosine transformation
Inventor: KIN KEISHIYOU
IPC: G06F17/14
Filed: 1991-09-10
Abstract: PURPOSE: To carry out the two-dimensional DCT at a high speed by performing the two-dimensional DCT processing to the (N×N) digital data through N times of one-dimensional DCT, the addition and a shift process. CONSTITUTION: A buffer 100 inputs the (N×N) digital data, and a reconstruction part 200 rearranges the digital data into N pieces of groups so as to ensure the addition of cosine functions equal to the core of the one-dimensional DCT and in order to transform the multiplication of cosine functions, i.e., the core of the two-dimensional DCT into the addition of cosine functions. A 1st adder 300 performs the addition or subtraction of the groups of odd order numbers corresponding to the groups of even order numbers adjacent to each other among those N pieces of rearranged groups and generates N/2 pieces of groups. These generated groups are sent to a one-dimensional pct part 400 where the one-dimensional DCT data to the 2/N pieces of groups are generated.  A 2nd adder 500 generates the two-dimensional DCT data by carrying out the addition/ subtraction and a shift operation to the one-dimensional DCT data at log2 N pieces of stages.

Title: Liquid crystal display device
Inventor: TAMAOKA EIJI
IPC: G09F9/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device with which a good display is obtainable and the time for packing liquid crystals is shortened by making the thickness in the spacing direction of both substrates of regions to be packed with the liquid crystals uniform and uniformly injecting the liquid crystals. SOLUTION: Color filters 2 are formed on the first substrate 1 and are coated with a coating material 3 to form first electrodes 4. Second electrodes 7 are formed on the second substrate 6 and an oriented film 5 is formed thereon. The first substrates 1 and the second substrate 6 are adhered by peripheral sealing material 11 made of a resin. Packing sealing materials 13 are packed in the regions on the inner side of the peripheral sealing materials 11 and on the peripheries of the color filters 2, the coating materials 3 and the oriented films 5 in the display regions. As a result, the spaces on the peripheral of the display regions do not exist any more and the uniform liquid crystal gap is obtd. The liquid crystals packed from the injection port 14 are uniformly packed.  The liquid crystals 9 are thus packed into the gaps formed of the first and second substrate 6 and the peripheral sealing materials 11.

A DC current command means 7 controls the output from a converter circuit 2 by outputting a DC current command value dependent on the rotational speed command and a PWM duty. The PWM duty is set higher than a given upper limit, lower than a given lower limit or between the upper and lower limits.

Title: Paper detector
Inventor: MIZUNO TOSHIAKI
IPC: B41J29/50
Filed: 1988-09-15
Abstract: PURPOSE:To detect various types of paper by a construction wherein a carriage is moved along a platen and a reflection board, and the presence of paper is judged by a control means when a light-reflecting sensor receives a reflected light other than an alternating reflected light which is inputted in a printing paper unloaded state. CONSTITUTION:In the state that paper 9 is loaded on a platen 3 so as to cover a part of a reflection board 2, a reflected light is inputted to a light-receiving element PTR by the quantity of light of a fixed level according to the reflectance of the paper 9 when a sensor 1R is moved to a position opposed to the paper 9. When the input to a multivibrator MBR is turned from an alternating signal to a fixed-level signal, a signal outputted from a terminal OUTR to a CPU is reversed after a fixed time has elapsed from the trigger of rising of a lastly inputted signal. Succeedingly, based on this reversed signal the CPU judges that at this time the sensor 1R is disposed opposedly to the left end of the light-untransmittable paper 9. A left margin as a printing start position is determined referring to the left end position, and a printing is started at the left margin.

Title: Document picture input device
Inventor: NAKAJIMA KEISUKE
IPC: H04N1/10
Filed: 1986-10-01
Abstract: PURPOSE:To attain an original larger than the original read width to be passed through without folding the original by adopting the structure that at least one side of the carrying path of the original is opened. CONSTITUTION:When the original 100 is loaded from the left, a light radiated from an LED 520 to a photodiode 501 is shut, the loading of the original 100 is sensed and the paper is carried between two original carrying rollers 505 and 507. A support 510 is of cunti-lever structure and since a gap 511 is provided to one side, the paper having a width in excess of the read width is passed through. Even with a facsimile equipment of A6 sizehaving a small original read width, the adoption of the structure with open one side of the carrying path allows the original of A4 size to be sent without being cut-off or folded.

Title: Electrophotographic image controlling method
Inventor: FURUICHI YASUSHI
IPC: G03G15/06
Filed: 1982-12-24
Abstract: PURPOSE:To prevent stains on a background by setting a developing bias value from a suspension period and a developer fatigue degree and gradually lowering said value in accordance with the number of copies produced from the start of a copying machine. CONSTITUTION:A developer-based copy quantity detection circuit 11 counts the number of copies from the time of feeding a fresh developer, and sends its signal to a bias control circuit 12. A copy quantity detection circuit 13 is cleared when a copying machine is suspended, and starts to count when it starts operation, and sends its signal to the circuit 12. A suspension time detection circuit 14 detects a length of time from the suspension of the machine or the stop of agitation of the developer to the restart, and sends its digitized value to the circuit 12. The circuit 12 receives these signals, sets a correct bias voltage value, and applies it to a developing roller 17. A toner is triboelectrified in polarity opposite to an electrostatic latent image by agitation with a blade wheel 19. The polarity of the bias voltage is opposite to that of the toner, lower than potential at the image part, and somewhat higher than potential at the background. Therefore, the toner adheres to the image part but not to the background part, thus preventing background stains.

IPC: G06T7/00
Filed: 1991-08-19
Abstract: PURPOSE:To set up an optimum binarizing threshold to obtain a binary image of a wiring pattern formed on a printed substrate. CONSTITUTION:Reflected light information and transmitted light information are electrically converted and digitized through A/D conversion parts 210, 220 as a printed substrate signal PS and a hole signal HS. The signal HS is binarized by a binarizing processing part 240 and delayed by a phase compensating part 280 as a delayed hole signal HDS. Both signals PS, HDS are logically synthesized by a masking processing part 230 and the value of the signal PS corresponding to a position on which the signal HDS is '1' is set up to '0' to obtain a compensated signal CS. A histogram forming part 250 forms a histogram G by using the signal CS, a binarizing threshold T is set up based upon the histogram G and a binarizing circuit 270 binarizes the signal PS. Consequently the information of a position on which light is reflected by a stage through a through hole is forcedly set up to a prescribed value and the position of masking processing can be accurately determined.
