Title: Scan converter circuit
Inventor: IHARA AKINORI
IPC: H04N5/073
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the image quality by replacing a read clock signal with a clock signal generated by a pre-stage digital system after a read PLL circuit is locked so as to allow a read side and write side use the same clock signal thereby obtaining a display image with less jitter. SOLUTION: In a scan converter circuit 4-3, a read clock is replaced with a clock signal generated by a pre-stage digital system 4-1 after a read PLL circuit 4-4 is locked in the scan convert operation such as double speed conversion synchronized with the read and write sides. Thus, in the scan converter circuit 4-3 in the scan convert operation synchronized with the read and write sides, one clock generating PLL circuit is enough for the purpose and the write and read sides use the same clock signal, then the display image with less jitter is obtain and the image quality is improved.

Title: Optical reading card and its read controller
Inventor: HIRAMITSU SEIJI
IPC: B42D15/10
Filed: 1990-04-19
Abstract: PURPOSE:To prevent deviation of data to be read from occurring when an optical reading card is folded by adding a deletion mark to a timing mark area including a timing mark to show a fact that the output read in response to the timing mark is invalidated. CONSTITUTION:A deletion mark 16 is added to a timing mark area including a timing mark TM to show a fact that the data read in response to the mark TM is invalidated. The mark 16 is provided in response to a position where an optical reading card is generally folded by a user. Thus a folding line is set on the mark 16 and doubles as a kind of TM. However a read controller invalidates the data read in response to the TM. Thus it is possible to obtain an optical reading card that produces no data deviation even if the card is intentionally folded.

Title: Failure diagnostic device for evaporative fuel supply system
Inventor: NISHIOKA FUTOSHI
IPC: F02M25/08
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To determine leakage with high precision. SOLUTION: A control valve 24, a canister 22, and a purge valve 25 are connected to a purge passage 21 connecting a fuel tank 7 to an intake passage 2, and an atmospheric air releasing valve 28 is connected to the canister 22. While the control valve 24 is opened and the valve 28 is closed, the purge valve 25 is opened, so that the inside of a fuel tank 7 is sucked by means of an intake negative pressure. Then, the purge valve 25 is closed, and the purge passage 21 is cut off from the atmospheric air so as to be held in a sealed condition. After the lapse of the predetermined time, if a tank internal pressure (a pressure increase from the predetermined negative pressure) is within a determination threshold value, it is determined that leakage is not caused.  The predetermined negative pressure in a start of leakage determination always takes the same value without respect to a difference in an operation condition of an engine. The predetermined negative pressure is always kept constant, but a leakage determining condition may be changed according to a dimension of the predetermined negative pressure in a start of leakage determination or according to a differential pressure between the predetermined negative pressure and the atmospheric pressure.

Title: Display/printing device
Inventor: KUDO MAKOTO
IPC: G06F3/12
Filed: 1989-04-24
Abstract: PURPOSE:To increase the speed of a display/printing device by providing a trapezoid dividing means which divides character data of the stroke system into trapezoids and a trapezoid data storage part where character data divided to trapezoids is stored. CONSTITUTION:Character data of the stroke system generated by a character data part A is divided into trapezoid data by a trapezoid dividing means B, and trapezoid data is stored in a data storage part C. When the display/printing stage is started after storage of one page into the data storage part C or the data storage part C is filled up with data not to have a space for data or a display part E terminates output of the preceding page, a dot generating part D converts trapezoid data stored in the data storage part C into dot data. Finally, the display part E displays/prints dot data. Since display and character generation are performed in parallel in this manner, the speed is increased.

Filed: 1979-08-15
Abstract: PURPOSE: To make it possible to extend an address space by employing stack structure for a bank selecting method and by performing push-down and hop-up operations under the commands of a processor.  
     CONSTITUTION: It is assumed that the contents of register 7 is "00" and that of bank register 8-0 is "000". In this case, "101" is sent to the data bus, output port B of adaptor 4 is assigned and a control signal is written. As a result,  the contents of register 7 shows "01" and "101" is written in bank register 8-1. Next, when "110" is sent to the data bus and the similar operation is performed, "110" is written in bank register 8-2. Consequently, memory banks are selected in the order of 3-0, 3-5 and 3- 6. Then, when output port A is assigned and write operation is commanded, the contents of register 7 becomes "01" and register 8-1 is assigned, thereby selecting bank 8-0 through the similar operation. Thus, memory banks are selected in the order of 8-2, 8-1 and 8-1 and then the initial bank is to be selected.

Abstract: PURPOSE: To produce smooth and sufficiently cooled thin metal strips, by depositing and solidifying molten metal on the outer circumferential surface of a roll rotating at high speed, and contacting a plurality of auxiliary rolls of small diameter with said roll.  
     CONSTITUTION: After melting the metal charged in a tubular container 1 in a heating furnace 10, this molten metal 3 is injected to the outside of a main roll 5 which is being rotating, from a nozzle 2 by applying gas pressure. The molten metal 3 is made to contact with the surface of the roll 5, and is cooled and solidified. Thus obtained thin metal strip 4 is passed through between the roll 5 and auxiliary rolls 7, 8, 9. In this case, releasing of the strip 4 passed through the roll 5 and roll 7 from the roll 5 is prevented by the gas pressure being injected 11, and the strip is rolled and cooled in the rolls 8, 9 in succession. Due to injection of gas from injection pipes 12, 13, prevention of releasing and cooling of the strip 4 are achieved.
