摘要： 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.

摘要： A fuel injection device includes a cylinder that defines a pressure chamber at an end portion of a nozzle needle. A floating plate as a control member is placed in the cylinder. A cutout portion and multiple grooves are formed in the floating plate. The cutout portion and the grooves causes a gap between a large-diameter inner circumferential surface and an outer circumferential surface to communicate with the pressure chamber. The cutout portion and the grooves reduce a contact surface portion between the cylinder and the floating plate and divide the contact surface portion into multiple island portions. As a result, it is possible to reduce the contact surface portion.

摘要： 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.

摘要： 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.

摘要： A fuel injection device includes a cylinder defining a pressure chamber at an end portion of a nozzle needle. In the cylinder, a floating plate is provided as a controlling member of fuel pressure. An orifice member and a nozzle body are lined by an annular positioning member, using a circular peripheral surface of the orifice member and a circular peripheral surface of the nozzle body as a reference surface. Thereby, radial locations of the nozzle body and the orifice member are defined. Furthermore, a location of the floating plate is defined by the nozzle body with the nozzle needle. Therefore, the floating plate can be located to a proper location relative to the orifice member.

摘要： 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.

摘要： 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. Therefore, when the user moves frequently and the possibility of the equipment entering the service area of the cell station from the outside is high, the control channel receiving state brings about frequently. When the user does not move frequently and the possibility of the equipment entering the service area of the cell station from the outside is low, the frequency of bring about the control channel receiving state becomes low and thus emphasis is laid on the consumption of the battery.
摘要翻译：本发明涉及一种便携式终端设备，其与控制信道的同步被断开时通过间歇地接收控制信道与控制信道建立同步。当与控制信道的同步被解除时，设备在每个时间段t1（ST3-ST10）被设置为一段时间W2的控制信道接收状态。当在设定为N（= X + 5）倍的接收状态（X =过去一小时内的非同步状态）中未建立与控制信道的同步时，设备被设置为转移到控制每个时间段t2的时间段W2的通道接收状态（ST2和ST11-ST18）。用户移动越频繁，则失去同步的时间X越大，因此N越大那个量，直到控制接收状态的每个周期之间的时间间隔t1转移到间隔t2为止的时间间隔为延长因此，当用户频繁移动，并且设备从外部进入小区的服务区域的可能性高时，控制信道接收状态频繁地引起。当用户不频繁移动，并且从外部进入小区站的服务区域的设备的可能性低时，导致控制信道接收状态的频率变低，因此重点放在电池的消耗上。
