Patent JP-H01311548-A (JP)
Title: Electron flood
Inventor: TASHIRO NAOTO
IPC: H01J37/04
Filed: 1988-06-10
Abstract: PURPOSE:To momentarily detect breaking and ground fault of a filament while instantly stopping ion implantation treatment by detecting non-uniformity between the filament currents. CONSTITUTION:When a filament 1 is broken, a current flowing to the filament 1 becomes naught and a signal is outputted from a hole element current sensor 8. Then, the signal is compared with a filament current control signal at a comparator 11 for outputting a difference signal. This differential signal is compared with the reference voltage at a comparator 12 and when a difference is larger then the reference voltage, an ion implantation stop signal is outputted. On the other hand, when the filament 1 has a ground fault, a current bias is generated on the wirings 7a and 7b so that a signal is outputted from a hole element sensor 6. This signal is compared with the reference voltage at a comparator 13 and when a difference is larger than the prescribed value, the ion implantation stop signal is outputted. Accordingly, breaking and the ground fault can be momentarily detected.

Title: Device for increasing fuel at acceleration of engine
Inventor: SUZUKI JIYUNICHI
IPC: F02M7/06
Filed: 1981-09-11
Abstract: PURPOSE:To prevent the fuel concentration of an air fuel mixture from becoming too  low at the time of the sharp opening of a throttle valve, by providing a resistance  valve near the atmosphere end of an intake passage and providing a buffer chamber  between the resistance valve and the intake passage to keep the flow rate of intake  air from increasing at the time of the sharp opening of the throttle valve. CONSTITUTION:When an engine is idling, the flow rate of intake air is low and a resistance valve 18 provided near the atmosphere end of an intake passage 4 is kept at the  minimum degree of opening so that air is sucked in the direction of an arrow. When a  throttle valve 6 is sharply opened, the intense negative intake pressure of a combustion  chamber 3 propagates to the upstream side of the throttle valve so that fuel is ejected  from a fuel nozzle 7 and simultaneously air is introduced from the atmosphere. At that  time, the resistance valve 18 is at the minimum degree of opening so that it temporarily prevents the sharp increase of the introduced air and then receives the negative intake pressure on the top and the atmospheric pressure on the bottom and is  thereby swung upwards against gravity. As a result, the degree of opening of the resistance valve 18 is heightened to increase the flow rate of the air. In this case, the pressure fluctuation of the air in an intake distribution chamber 11 as a buffer chamber is  suppressed.

Title: Exchange
Inventor: TSUNODA KEIJI
IPC: H04Q3/00
Filed: 1994-06-24
Abstract: PURPOSE:To considerably improve the processing efficiency of software processing by processing data while a processing unit such as physical layer processing is in matching with a data width of a processor mounted on an exchange. CONSTITUTION:A receiver side FIFO 2701 provides an output of received serial data in the unit of n-bits being a data width of a CPU 2703. The CPU 2703 reads data in n-bit width from the receiver FIFO 2701 and applies prescribed processing to the data. On the other hand, the CPU converts the data in n-bit width outputted from the transmitter side into serial data and provides an output. The physical layer processing in the CPU 2703 is more efficient than the case of serial or 8-bit parallel processing having been executed in a conventional hardware by forming a width of data sent/received between the FIFO 2701, 2702 and the CPU 2703 to be equal to a data width (n) read/written at once by the CPU 2703 in this way.

Filed: 1995-05-18
Abstract: PURPOSE: To increase filling speed and improve final contents accuracy by a method wherein after initial contents are determined a bottle is lowered, and the contents are re-filled while transporting the bottle in a predetermined section with a lower end of an outer tube opening its exhaust port to determine final contents. CONSTITUTION: When filling is started, a lower end of an outer tube 2 is positioned above an upper end of an exhaust port 6. As filling is done from a liquid injection port 10 and when first filling is completed, the upper end of the exhaust port 6 is clogged by filled liquid and no exhaustion is done, so that filling is stopped. After a state that the liquid has been filled to a first filled liquid level when the filling is stopped is determined, a container 9 is lowered, so that the lower end of the outer tube 2 is brought to a position lower than an inner tube 3 and the upper end of the exhaust port 6. Then as the container 9 lowers, the filled liquid level also lowers, and since the exhaust port 6 is opened again, the liquid is filled again.  By providing a correction section wherein the container can be transported by a predetermined section to maintain the state, the liquid can be filled to the lower end of the outer tube 2, thereby determining final contents.
