Abstract: There is disclosed a pressure regulating valve which effectively reduces a noise of a fuel pressure regulating valve without relation to a flow amount of a fuel. In this valve, a flow collision preventing member (35) is fitted to an upper end opening portion of a bush (26), and an upper portion of the flow collision preventing member (35) is protruded to a side of a valve body (33) rather than a valve seat (28) (an upper end surface of the bush (26)). A plurality of flow passages (36) for flowing the fuel in an axial direction thereof (in a downward direction) along an inner peripheral surface of the bush (26) are formed in an outer peripheral portion of the flow collision preventing member (35) with a uniform interval. A runoff recess portion (37) running off a protruding portion of the flow collision preventing member (35) is formed in the valve body (33) positioned immediately above the valve seat (28).

Abstract: A fuel pump suctions fuel from a fuel tank and discharges it into a pressure tank. Then, the fuel pump suctions the fuel from the pressure tank and pressurizes it. Then, the fuel pump discharges the pressurized fuel toward an engine side through a fuel discharge pipeline. A pressure control valve is opened to communicate an inside of the fuel tank and an inside of the pressure tank when a pressure in the pressure tank becomes equal to or greater than a predetermined pressure. A canister receives activated carbons for absorbing vapor fuel from the fuel tank. A pressurizing pump suctions the vapor fuel from the canister and pressurizes it. The pressurized vapor fuel is then discharged from the pressurizing pump into the pressure tank, so that the vapor fuel is dissolved into the fuel in the pressure tank.

Abstract: With the present communication device, when a radio section 2 receives a radio signal containing a selective call number corresponding with one of selective call numbers registered in the device, a control section 12 stores a message signal subsequent to the selective call number into RAM 5. Then, a message code conversion section 8 converts each of character/symbol codes constituting the message signal into a legible letter for display, or into a message. In association, a searching section 7 checks whether or not the message contains a caller's name correspondent with name data previously stored in RAM 6. When the message is found to contain a caller's name correspondent with one of the name data stored in RAM 6, a control section 12 retrieves a sound pattern registered in connection with that caller's name, and instructs a notification section 11 to notify the user of a call by delivering the sound pattern, and at the same time a display section 10 to display the message as well as the caller's name.

Abstract: The communication device includes a communication microcomputer 203 and an information-processing microcomputer 207. The communication microcomputer 203 has a line quality measuring section 301, a battery level measuring section 302, a data table 304, and a data transmission/reception decision section 303. The information-processing microcomputer 207 has a data transmission/reception prediction section 307 and a communication processing section 305. The electric field level, degradation in line quality, and the remaining amount of a battery are periodically monitored during data communication such as electronic mail reception. The data transmission/reception decision section 303 implements a decision process based on various predetermined information sets acquired through the monitoring. When deciding that the line is disconnected during communication, the data transmission/reception decision section 303 interrupts the mail reception and performs a logging-out with the server, thus disconnecting the line.

Abstract: A residual fuel quantity measuring device for automobiles has a fuel flow rate sensor provided in a filler neck of a fuel tank for measuring the flow rate of liquid fuel supplied to a fuel tank. A computer computes the quantity of liquid fuel remaining in the fuel tank from a previously stored residual quantity of liquid fuel, the measured fuel flow rate, the injection rate of fuel from fuel injection valves, and the purge quantity of fuel evaporated in the fuel tank. A fuel meter visually displays the thus computed residual quantity of liquid fuel in the fuel tank.

Each conversion table is used to convert a numeral code to a display character code for displaying visual information on screen. A table selector selects a conversion table from the plurality of conversion tables according to a table selection code which is included in the message data. A converter converts each numeral code included in message data following the table selection code into a display character code by using a selected conversion table.

Abstract: An antidissipation apparatus for evaporated fuel vapor for an internal combustion engine. A purge passage connects the intake manifold and the fuel tank. A canister is installed in the purge passage and adsorbs evaporated fuel vapor generated in the fuel tank. A purge pump is installed in the purge passage and delivers the adsorbed evaporated fuel vapor to the intake manifold. Since the purge pump is driven by at least a part of a fuel flow in the fuel passage, the purge pump can change its discharge amount of the adsorbed evaporated fuel vapor to the intake manifold according to an amount of the fuel flow in the fuel passage. Therefore, the evaporated fuel vapor which is adsorbed at the canister can be supplied (purged) to the intake manifold by the purge pump forcibly even if the engine is a lean-burn type which can not employ large negative pressure of the intake manifold.

Abstract: In a repeat call paging system, a paging signal is transmitted in a sequence of frames each comprising a series of fields respectively assigned to different pagers. Each of the fields contains a copy of a message for a pager and the message copy is repeatedly transmitted in successive frames. The front end of the pager is activated to produce a baseband signal to determine whether a field assigned to the pager is contained therein and to synchronize the pager to a frame. If the assigned field is not contained in the baseband signal, the front end is deactivated until the assigned field appears in a subsequent frame. If the assigned field is contained in the baseband signal, a copy of the message for the pager is searched. If the message copy is not detected, the front end is deactivated until the assigned field appears in the next frame and a search is repeated for a message copy.

Abstract: The present invention provides a regenerative pump for supplying fuel into an injection device for an internal combustion engine. The regenerative pump has a longer pressurizing passage and a slanted discharge port connected thereto and formed at an outer periphery thereof. The pressure loss in the pump is small because the fuel flows smoothly into the discharge port from the pressurizing passage, and accordingly the efficiency of the pump is high and the pump can be made small in size at the same time.

Abstract: An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure.

Abstract: In apparatus for injecting fuel into an internal combustion engine, a flip-flop used for frequency dividing an engine rotational angle signal is arranged to be reset when a basic injection pulse is not coincident with a cylinder-determining pulse signal. The basic injection pulse is produced by a Q/N charge-discharge circuit arranged to start charging a capacitor in response to a leading edge of an output pulse from the flip-flop and to start discharging the same in response to a trailing edge of the same where time constant on charging is constant and time constant on discharging is variable depending on the quantity Q of intake air of the engine. The basic injection pulse is used to produce final injection pulse with which fuel injection valves are operated where the width of the basic injection pulse determines the basic amount of fuel to be injected. After the flip-flop is reset, its output pulse is shifted by 180.degree.
