Abstract: In a fuel injection device, a control body has a pressure control chamber, an inflow port and an outflow port. The inflow port and the outflow port are opened at an abutting surface exposed to the pressure control chamber. In the pressure control chamber is arranged a floating plate for pressing the abutting surface by a pressing surface with the pressure of the fuel to interrupt communication between the inflow port and the pressure control chamber. The abutting surface of the control body is provided with an outer opposite surface portion opposite to an outer edge of the pressing surface in a displacement axis direction of the floating plate, and the outer opposite surface portion has a special depressed portion that is depressed in the displacement axis direction and that extends along the shape of the outer edge of the pressing surface.

Abstract: The invention has an object for improving response of a fuel injection device. A flow-in recessed portion and a flow-out recessed portion are formed at a press-contacting surface of a floating plate, which is movably accommodated in a pressure control chamber. A flow-in port and a flow-out port are formed at a pressure control surface of a valve body. The flow-in port is opened to the flow-in recessed portion, while the flow-out port is opened to the flow-out recessed portion. When the floating plate is moved upwardly and the press-contacting surface is brought into contact with the pressure control surface, the flow-in port is surely closed.

Abstract: In a fluid injection nozzle, a leading end portion of a needle is provided with a first conical surface, a second conical surface and a notch. A seat line between the first and second conical surfaces comes in contact with a seat surface. A gap between the first conical surface and the seat surface gradually narrowed as going downstream, and a gap between the second conical surface and the seat surface gradually widened as going downstream. The notch extends from an upstream end of the first conical surface to a side opposite from the second conical surface to face the seat surface.

Abstract: A solenoid valve is provided which may be used to inject fuel into an internal combustion engine for automotive vehicles. The solenoid valve includes an armature and stator attracting the armature to open a fluid passage. The solenoid valve also includes a retaining nut and an end body. The retaining nut engages a housing to retain a hollow cylindrical stator casing in the housing. The end body is joined to the casing in alignment therewith to hold the stator within the casing without subjecting the stator to the pressure produced by the engagement of the retaining nut with the housing. This minimizes undesirable loads on the stator.

Abstract: This invention relates to a portable terminal equipment establishing synchronism with a control channel by intermittently receiving the control channel when the synchronism with the control channel is made off. When the synchronism with the control channel is made off, the equipment is set to a control channel receiving state for a period of time W2 every period of time t1 (ST3-ST10). When the synchronism with the control channel is not established in the receiving state which is set to N (=X+5) times (X=number of off-synchronism during the past one hour), the equipment is set to shifting to a control channel receiving state for the period of time W2 every period of time t2 (ST2 and ST11-ST18). The more frequently a user moves, the larger the time X of off-synchronism becomes and thus N becomes larger by that amount so that a time period until the interval t1 between each period of the control receiving state is shift to the interval t2, is prolonged.

Abstract: This invention relates to a portable terminal equipment which receives intermittently a control channel transmitted from a cell station in a standby state. When the equipment shifts to the standby state, the equipment is brought into a receiving state to receive intermittently the control channel (PCH) for a set period of time W1 at every 1.2 seconds (ST22-ST25 and ST32). In addition, the equipment judges the receiving state from judging information of the receiving state such as the intensity of the electric field in receiving time and the presence/absence of an error in the received data (ST27 and ST33). In a power saving mode, when the equipment keeps on receiving the control channel in a good state for a set period of time while the equipment receives the control channel at every 1.2 seconds, the equipment is brought into a receiving state to receive the control channel at every 2.4 seconds (ST33-ST35).

Abstract: This invention relates to a portable terminal equipment using a battery as a power source. The equipment determines whether or not battery voltage VB is lower than a voltage value V1 in a standby state or a speaking state (ST1 and ST8). The voltage value V1 is set to such a value that the equipment is capable of generating an outgoing call and making a speech during a set period of time, when the battery voltage VB is equal to the value V1. When VB<V1, the equipment shifts to a low-consumption standby mode in which a small amount of current is consumed (ST14). When the equipment is set to a speaking state, it generates a warning by means of alerting voice and so on to warn the user that the telephone communication will be broken after a expiration of a set period of time (ST10) .
