Title: Fuel supply device for internal combustion engine
Inventor: TSUGE MASAKUNI
IPC: F02M37/10
Filed: 1985-08-06
Abstract: PURPOSE:To ensure a requisite minimum quantity of fuel circulated, by controlling a rotational speed of a fuel pump driving motor according to an output from a sensor which output represents pressure in a fuel supply pipe, and thereby maintaining the pressure in the fuel supply pipe constant irrespective of a fuel injection quantity from an injection nozzle. CONSTITUTION:Pressure in a fuel supply pipe 14 is detected by a pressure sensor 12, and a detected pressure value is supplied to a deviation computing means 13, where the value is compared with a target pressure value supplied from a target value setting means 17. The deviation computing means 13 computes a rotational speed control signal according to deviation between the detected pressure value and the target value, and supplies the deviation to a variable frequency oscillator 18. Then, the variable frequency oscillator 18 changes an oscillation output frequency according to the rotational speed control signal. Accordingly, the rotational speed of a driving motor 20 is changed to thereby change a discharge quantity from a fuel pump 2. With this arrangement, there is not generated pressure fluctuation in the fuel supply pipe 14 due to difference between a response speed of a fuel pressure regulator 6 and a fuel control speed of an injection nozzle 4, thereby ensuring a requisite minimum quantity of fuel circulated.

IPC: H01L21/027
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To improve positional accuracy of pattern exposure by drift correction by performing correction process two times before exposure process in electron beam lithography. SOLUTION: In a method for electron beam lithography which repeats an exposure process (S5-S7) in which a resist on the surface of a wafer is irradiated with an electron beam for performing pattern exposure and a correction process (S3) in which a reference pattern provided on a specified position on the surface of wafer is irradiated with the electron beam for measuring a drift value of the electron beam to correct a drift of the electron beam, the drift of the electron beam is predicted and corrected based on a drift speed which is calculated based on a time interval between two correction processes (S3) which are performed before the exposure process (S7) and drift values which is measured in these two correction processes, in the exposure process (S5-S7).  Thereby the pattern exposure is performed while predicting and correcting a drift quantity without irradiating the reference pattern with the electron beam.

Title: Semiconductor storage circuit
Inventor: KOSHIZUKA ATSUO
IPC: G11C11/41
Filed: 1992-06-05
Abstract: PURPOSE:To prevent the occurrence of a malfunction caused by a coupling capacitance between signal lines by controlling the write operations to storage elements by a single signal line connected through a driving transistor. CONSTITUTION:When a write signal line W-bl is made high and a writing is performed, the potential of the line W-bl located on the negative side of a coupling capacitance C1 between the signal line W-bl and a read signal line R-blt is risen and the potential of the plus side signal line R-blt rises higher. On the other hand, in a coupling capacitance C2 between the signal line W-bl and a read signal line R-blc, the minus side signal line W-bl potential rises and therefore, the plus side signal line R-blc is risen higher. This, when the capacitances C1 and C2 vary, the signal level between the two signal lines R-blc and R-blt rises as a whole. However, the relative signal level difference between the two signal levels does not change. Thus, a malfunction caused by coupling capacitances C1 and C2 is eliminated.
