Title: Suction control method for internal-combustion engine
Inventor: OKUMURA TAKESHI
IPC: F02B31/08
Filed: 1984-03-12
Abstract: PURPOSE:To prevent worsening of operation performance during opening of a straight port, by a method wherein a valve, opening and closing a straight port, formed in a position facing a helical passage, is opened only when an air-fuel ratio exceeds a given value. CONSTITUTION:A suction passage 7, leading to a suction port 7a, is branched into a helical passage 11, producing swirl, and a straight port 12 which linearly sucks in a direction in which the swirl is disappeared during opening of a control valve 13. Based on various detecting values around the output of a lean sensor 33, a controller device 30 controls mainly an amount of fuel injected, and additionally controls an electromagnetic valve 19 for control of a negative pressure actuator 16, and this opens and closes the control valve 13 for the straight port. In which case, when an air-fuel ratio is in a lean condition, the valve 13 is alway brought into a close state, and this prevents worsening of operation performance because of the valve being opened to disappear the swirl ratio.

Title: Semiconductor device
Inventor: MATSUZAWA KAZUYA
IPC: H01L27/04
Filed: 1992-03-04
Abstract: PURPOSE:To improve a break-down resistance in a device isolation region, by implanting electric charges into a charge storage layer in the device isolation region to provide a higher threshold of parasitic MOSFET in the device isolation region. CONSTITUTION:A p well layer l is formed on a surface of a silicon substrate 30, and a p layer 2 is formed in a place for a device isolation region. An oxide film 3, a nitride film 4, and an oxide film 9 are formed to complete device isolation. When a high voltage is applied to a drain electrode 15, impact ionization takes place in a dashed line as indicated in the illustration. Then, electrons generated here are injected through the oxide film 3 in the nitride film 4 so that an electron trap is formed. Once the electron trap is formed, electrons, which causes the impact ionization, can hardly be induced even for a high voltage at a drain electrode 15. Consequently, a break-down resistance is improved in the device isolation region. Moreover, the nitride film 4 made of a solid material protects a silicon substrate 30 from stress of volume expansion when the oxide film 9 is formed.
