In a cordless telephone system, a master unit adds to a registration signal an identification (ID) code assigned to a slave unit connectable to the master unit, a master unit transmission password, and an ID code assigned to the master unit, and sends the resulting registration signal to the slave unit. On receiving the registration signal, the slave unit determines whether or not the master unit transmission password is identical with a slave unit password stored therein. If the former is identical with the latter, the slave unit writes the master unit ID code therein, adds the master unit ID code, slave unit transmission password, and slave unit ID code to an end-of-registration signal, and then sends the signal to the master unit. On receiving the end-of-registration signal, the master unit writes the slave unit ID code included in the signal if the slave unit transmission password is identical with a password stored therein.

A cordless telephone system or similar mobile radio communication system which limits the service available for a mobile unit or radio terminal in an exclusive zone assigned to the terminal and removes the limitation in a common zone while opening all the zones to a particular radio terminal. Assuming a single building accommodating a plurality of companies, the area where radio terminals can be serviced is limited on a companay basis. All the terminals belonging to the respective companies are serviced at a restaurant, lobby or similar common space inside the building. An exclusive terminal for a guard, for example, is serviced in all the arears inside the building.

A bill retention device includes a relatively long guide belt which has one end thereof secured to a first rotary member and the other end to a second rotary member and is wound on the first rotary member when no bill isretained at all. For accommodating bills, the second rotary member is rotated to wind the guide belt and also wind the bills tightly thereon. In accordance with winding of the second rotary member, the guide belt is unwound from the first rotary member. Thus, the guide belt is finally wound on the second rotary member many times resulting in winding up of a large number of bills. By having the guide belt wound on the first rotary member simultaneously with the reverse rotation of the second rotary member, the retained bills are unwound from the second rotary member one by one whereby the bills can be automatically returned.

A control device (7) of a cylinder direct injection type internal combustion engine (1) controls a fuel injection device (4) and an ignition device (5), executes injection of the fuel and ignition over multiple times, and executes a control of varying an interval between a timing of the injection of the fuel and a timing of the ignition, at the time of an ignition start in which the fuel is injected into a combustion chamber (3) in an expansion stroke with rotation of an output shaft (6) is stopped state and the fuel is ignited to start the rotation of the output shaft (6). The control device (7) varies the interval between the timing of the injection of the fuel and the timing of the ignition by adjusting a correlation of a pitch of the injection of the fuel over multiple times and a pitch of the ignition over multiple times. Therefore, the internal combustion engine (1) and the control device (7) have an effect of being able to enhance the starting property.

A fuel supply system for an internal combustion engine includes a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.

When a K0 clutch 34 is interrupted to stop a direct injection engine 12 during vehicle running, if a stop position of a crankshaft 114 is out of a range of a target stop range φtarget, the once interrupted K0 clutch 34 is temporarily frictionally engaged to slightly rotate the crankshaft 114. As a result, the crankshaft 114 stopped near compression TDC (top dead center) is rotated to and stopped in a minimum region of pumping energy in combination with a pumping action. Since the minimum region of the pumping energy overlaps with the target stop range φtarget suitable for ignition start associated with a small assist torque at the time of engine start, the ignition start can properly be performed at the next engine start and the assist torque at the time of engine start can be reduced.

An object of the invention is to provide a technology enabling to determine the saturation vapor pressure of used fuel in a fuel injection control system for an internal combustion engine equipped with a low pressure fuel pump and a high pressure fuel pump. In the invention, to achieve the object, in the fuel injection control system for an internal combustion engine that controls the duty cycle of the high pressure fuel pump by proportional-integral control based on the difference between the discharge pressure of the high pressure fuel pump and a target pressure, generation of vapor is detected based on a tendency of change in an integral term used in the proportional integral control, and the saturation vapor pressure of used fuel is calculated from the fuel temperature and the engine speed at that time.

A start control device of a vehicular direct injection engine provided in a vehicle is configured to execute an ignition start to raise rotation of the direct injection engine at a start of the direct injection engine by fuel injection and multiple sparking performed for a predetermined cylinder in an expansion stroke out of multiple cylinders of the direct injection engine, the start control device of a vehicular direct injection engine reduces the number of times of sparking for the predetermined cylinder at the time of an ignition start of the direct injection engine as compared to an ignition start performed before the current ignition start based on ignition timing of the ignition start performed before the current ignition start.
摘要:
A fuel feed system which causes liquid fuel to evaporate so as to feed gaseous fuel, provided with an evaporator which includes a heater which heats the liquid fuel to vaporize it and an electric heater which adjusts the temperature of the heater. The heater has a heat conduction surface which supplies heat to the liquid fuel. A difference between the temperature of the heat conduction surface of the heater and the boiling point of the fuel at the evaporator is used as the basis to change the temperature of the heater and adjust the heat flux at the heat conduction surface.

A vehicle control device includes a direct-injection engine and an electric rotating machine connected to the engine, wherein the vehicle control device stops the engine after opening a throttle while maintaining an engine speed by the electric rotating machine at the time there is a request to stop the engine. The engine speed is preferably maintained by an output torque of the electric rotating machine at the time fuel supply to the engine is stopped and the throttle is opened. At the time the throttle is opened while fuel is continuously supplied to the engine, it is preferable to maintain the engine speed by allowing the electric rotating machine to generate electric power.
