Title: Fuel injection pump
Inventor: TOYODA YASUHIRO
IPC: F02M41/12
Filed: 1985-06-14
Abstract: PURPOSE:To prevent fuel from flowing back to a fuel pressure chamber of a plunger pump by way of a main overflow port during operation of a fuel cut valve as well as to miniaturize an automatic type valve, by installing a check valve between the fuel overflow port and a fuel receiver. CONSTITUTION:At the time of operation of a fuel cut valve 60, a plunger 12 performs rotational motion and reciprocating motion simultaneously like at the time of nonoperation of the valve 60. However, at the time of a suction stroke of a plunger pump 100, since a fuel intake passage 50 is cut off by the fuel cut valve 60, no fuel feed to a fuel pressure chamber 110 through this passage 50 takes place. And, a check valve 70 is installed at the downstream side of a fuel overflow port 110a, and a fuel passage between a fuel receiver 20 and the port 110a is intercepted by this check valve 70. Therefore, even at the time of the suction stroke of the plunger pump 100, there is no inrush of fuel into the fuel pressure chamber 110 through the fuel main overflow port 110a, thus inadvertent fuel injection is preventable from occurring.

IPC: H02P27/06
Filed: 1995-05-01
Abstract: PURPOSE: To correct the error of a pole position signal and to improve the torque control accuracy of a synchronous motor by judging that an error occurs at the signal when the absolute value of error power which is of the difference between the DC input power calculated value of an inverter to be provided and the machine output calculated value of the motor becomes a set value or more. CONSTITUTION: When an error occurs at the pole signal θ5 of a permanent magnet type synchronous motor 3, a torque control accuracy is lowered, and erroneous power ΔP is generated between the machine output calculated value Pm calculated by a multiplier 11 based on a torque command value and the DC input power calculated value PDC. Accordingly, when a set value is suitably decided in a window comparator 13 and the power ΔP becomes the set value or more, an informing signal is output, and hence the error of the position signal can be detected. Thus, the error of the pole position signal θf is corrected to improve the torque control accuracy of a synchronous generator.

Title: Network synchronizing system for basic interface
Inventor: TAKAHASHI YOSHINORI
IPC: H04L12/02
Filed: 1989-05-26
Abstract: PURPOSE:To attain priority selection and to ensure the switching between network synchronization clock and system clock when plural trunk lines are activated by providing a speech path witching section and a network synchronization clock extraction section or the like. CONSTITUTION:When an ISDN basic interface trunk line circuit (BICOT) is not used, the system clock (SCLK) of the speech path switching section (SPE) is used as a time division switch highway (HW) clock. Moreover, when the BICOT is used, a signal from an ISDN line network is converted into a T point interface via a device DSU and fed to the BICOT. Then the network synchronization clock extraction section (BCLK) extracts the network synchronization clock signal and the clock signal extracted by the BCLK is used as the HW clock via a clock changeover switch SW and the signal line CLK. Thus, when plural trunk lines are activated, the priority selection is attained and the network synchronization clock and the system clock are surely switched.
