Title: Optical communication network node
Inventor: NISHIO MAKOTO
IPC: H04L12/70
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To realize a compact and inexpensive optical communication network node. SOLUTION: An optical signal with arbitrary wavelength among wavelength multiplied optical signals is branched by a light branching and inserting circuit 110. The switching of this branched signal and an externally inputted signal from an external part is operated by an ATM switch 170. This signal after switching by the ATM switch 170 is combined with the wavelength multiplex signal by the light branching and inserting circuit 110. Thus, the number of cross points necessary for the optical switch circuit network can be reduced, and the miniaturization and cost reduction of a node can be attained compared with the conventional case where switching is operated without any branch.

Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a contact hole of a semiconductor device, wherein increase in contact resistance is prevented effectively even with a contact hole with a small but large aspect ratio. SOLUTION: A first insulating film 120, where an impurity is doped heavily at high concentration and a second insulating film 130 where, formed on the insulating film 120, an impurity is lightly doped at low concentration are dry- etched to open a contact hole. Then wet-etching is performed. Thus, the first insulating film 120, whose impurity concentration is high while wet-etching is high, is etched to complete a contact hole 150B with a lower-part width W2 widened, resulting in a wider exposed area of the contact hole 150. Thus, increase in contact resistance is prevented effectively.

Filed: 1989-08-08
Abstract: PURPOSE:To perform printing at an indicated printing position by a method wherein a printing position indication means indicates a printing position at the time of printing based on the overlapped state of a printing pattern on a preprinted pattern, which is applied on paper and can be seen through the printing position indication means. CONSTITUTION:An LCD controller 17 indicates a string of printing pattern data transmitted thereto on a liquid crystal display board 13. When a printer is loaded on paper to be printed 20, on the transparent liquid crystal display board 13, the indicated character printing pattern is seen overlappedly on a character frame on the paper 20 as a preprinted pattern 21. The printer is positionally corrected to obtain an optimum overlapped state as a printing position, thereby positioning the characters within the preprinted printing pattern 21. With the detection of the travel of a printing head 10 by a distance from a printing head position to the first-byte position of the liquid crystal-displayed printing pattern, a printing action is started here. Strings of printing pattern data are sequentially read from a memory of a control part 15 per byte at every travel of one line pitch and transmitted to a printing head driver 18, whereby data for one line is printed per 8 dots by the printing head 10.

Title: Direct memory access controller
Inventor: UEDA CHITOSHI
IPC: G06F13/28
Filed: 1988-08-16
Abstract: PURPOSE:To realize the direct memory access DMA transfer with the read data width different from the write data width by stacking the data equivalent to the least common multiple between both data widths into a DMA controller. CONSTITUTION:When a data request signal DRQ received from a peripheral control part is inputted to a DMA controller, a control part 1 outputs a read address to a read address part 3. Then an instruction is given to a data buffer 2 to hold data after the data output of a memory is decided to the read address. Then the least common multiples are compared with each other between the read data byte width and the write data byte width. If the read data byte number is smaller than the least common multiple, the data are stacked continuously until the coincidence is obtained between them. When the data stacking job is through, the write address is outputted to a write address part 4. At the same time, the stacked data are converted into the write data width and outputted to a write data converting part 5.

Abstract: PURPOSE:To widen an angle of field and to extremely facilitate the control of unequal colors and color slurring by using one signal line of plural display regions formed on a substrate as a common signal line and forming insulator films on switching elements for driving picture elements and the signal lines. CONSTITUTION:The X-direction signal line 4 is used commonly and the plural independent display regions 24-27 are formed on the array substrate 24. The insulator film 29 covering the entire part, the insulator film 30 which covers the regions 26, 27, and the insulator film 31 which covers the region 27 are successively formed thereon. A counter electrode substrate 28 is mounted on the substrate and a liquid crystal is sealed therebetween by using a sealing resin 21, following which the Y direction signal lines 3 and ICs 9, 10 for driving are packaged. The distances between the display regions can be decreased at the time of distributing the light from a light source, projecting the distributed light rays on the three display regions and projecting only the light rays in the desired picture element regions onto a screen through said regions and, therefore, the angle of the light rays to be condensed onto the screen is decreased and the change in the image plane colors according to the angles at which the image screen is viewed is eliminated. The adjustment of the unequal colors and the color slurring is thus extremely facilitated.

Title: Copying machine
Inventor: MATSUO HIROSHI
IPC: G03G15/00
Filed: 1985-09-17
Abstract: PURPOSE:To change successively copying conditions such as the form size and the number of copies to copy originals without resetting originals again by providing a reading means which reads out automatically contents stored in a memory before the start of the copying operation to set copying conditions. CONSTITUTION:Copying conditions such as the form size and the number of copies are set preliminarily to the memory, and stored contents are read out from the memory to set automatically copying conditions before the copying operation is started. Since copying conditions are set successively before the start of the copying operation, the same original is subjected to the copying processing successively in accordance with copying conditions stored preliminarily in the memory. For example, the original is set to an ADF only once to perform successively the copying processing based on plural copying conditions automatically. Thus, the trouble of resetting of the original is omitted, and the time of the copying processing is shortened as the whole because the original is fed only once.

Abstract: PURPOSE:To provide low cost circuit constitution, by providing two kinds of a temp. compensation circuit and a temp. control circuit connected to one A/D converter and changing over the logics of the open collector type logical circuits respectively connected to both circuits. CONSTITUTION:When P2 of a main control circuit 1 is set to a low level, the output sides of pen collector type logical negation circuits 3, 4 are turned OFF and the thermal resistor element 10 in the side of a temp. compensation circuit comes to a voltage dividing resistor along with a resistor 7 and the resistant change portion thereof is fed back to an A/D converter 2. However, the connection of the density change-over switch 11 in the side of a temp. control circuit becomes reactive because the circuit is brought to an open state. Next, when P2 of the main control circuit is set to a high level, the output sides of the circuits 3, 4 are turned ON and the resistors 8, 9 connected to the density change-over switch 11 come to a voltage dividing resistor and the resistance change portion thereof is fed back to the converter 2 but the thermal resistor element 10 becomes reactive. Therefore, only one converter 2 is used and cost reduction is attained.
