Title: Fuel injection device for internal combustion engine
Inventor: UEHARA TETSUYA
IPC: F02M51/00
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To reduce the speed of a needle valve at the optimum timing and reduce noise generated when it is seated even when a fuel pressure in a common rail is changed and controlled in accordance with operation conditions. SOLUTION: The needle valve of a fuel injection nozzle receives a fuel pressure in a fuel chamber in the direction of valve opening and receives a back pressure in a back pressure chamber in the direction of valve closing. When a solenoid valve is turned ON and a pressure in the back pressure chamber is opened onto a low pressure chamber side, the needle valve is lifted. When the solenoid valve is turned OFF, the needle valve moves in the direction of seating. The solenoid valve is again turned ON during a fixed period of time τg after a predetermined delay time τd to reduce a speed of the needle valve in seating. The optimum delay time τd is given in accordance with a common rail pressure and a fuel injection amount.

Title: Reception level measurement method and reception level measurement circuit
Inventor: ISHII TAKAHITO
IPC: H04B17/345
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a reception level measurement circuit that separately measures a desired wave level and an interference wave level and can accurately measure a level below an in-band noise level of a receiver wireless section by solving a problem that a conventional reception level measurement circuit cannot measure a level below an in-band noise level because the conventional circuit has measured a desired level including the interference wave level. SOLUTION: The reception level measurement circuit uses a desired wave level correction section 12 to use a desired wave level as it is at a level less than the in-band noise level and adds an RSSI detected by a wireless section to the desired wave level to correct it at a level more than the in-band noise level with respect to the desired wave level resulting from synthesizing desired wave components detected by each of desired wave/interference wave detection sections 9 so as to obtain a result of measurement of the received levels.
