An electromagnetic fuel injection valve is provided that includes a fuel inlet tube (26) extending from an outer end of a hollow fixed core (5), and a retainer pipe (23) that is inserted from the fuel inlet tube (26) into a hollow portion (21) of the fixed core (5) and supports a fixed end of a valve spring (22). The fuel inlet tube (26) is formed from a high hardness magnetic material, a retainer pipe 23-facing portion of the fuel inlet tube (26) is heated so as to form a softened region A, and this softened region A of the fuel inlet tube (26) is crimped toward the retainer pipe (23) so as to fix the retainer pipe (23) to the fuel inlet tube (26). In this way, even when the fuel inlet tube is formed from a high hardness magnetic material, the retainer pipe can be reliably fixed to the fuel inlet tube by crimping.

A throttle body includes: an intake passage (16) on which is provided a throttle valve; a pressure inlet passage hole (112) which has an aperture portion (46) on a downstream side of the throttle valve on the intake passage (16); and a sensor mounting portion (77) on which is mounted an intake pressure sensor (43) which detects pressure inside the intake passage (16) via the pressure inlet passage hole (112). The pressure inlet passage hole (112) is formed extending from an aperture portion (46) in an oblique direction relative to the direction in which the intake passage (16) extends so as to move away from the intake passage (16) as it approaches the upstream side of the extension direction of the intake passage (16).

An electric parts attaching structure for a throttle body includes: a throttle body (12) having an intake passage (16) in which a throttle valve (24) is arranged, and a housing (20) for accommodating electric parts formed on the outside thereof; an intake passage information detection sensor (43) which is attached to a bottom section (42) of said housing (20) for detecting information in said intake passage (16); and a circuit board (45) which is disposed on a side opposite to a side facing the bottom section (42), of said intake passage information detection sensor (43), and is attached to said housing (20) in state where connection pins (89) extending from the intake passage information detection sensor (43), are inserted into connection holes (100).
摘要:
A rewriting system in which a rewriting unit (2) transmits rewriting data for each predetermined data transfer unit as a data transfer command together with specified position data which represents a portion to be rewritten which corresponds to the rewriting data and prohibits the transmission of the data transfer command which contains the rewriting data when the whole of the rewriting data that is transmitted by the predetermined data transfer unit represents a predetermined value, and an on-board control unit (3) writes the rewriting data contained in the received data transfer command to the rewriting portion of the nonvolatile memory (10) represented by the specified position data in the received data transfer command and writes data representing the predetermined value in all portions of the nonvolatile memory (10) where the rewriting data cannot be obtained from the received data transfer command.

To inhibit vapor in a fuel flowing to a second fuel distribution path by shortening a fuel communicating pipe between first and second fuel distribution paths in respective sides of a throttle body, first and second throttle bodies (1,3) are arranged in parallel, first and second throttle valves (8,9) are attached to a single throttle valve shaft (5), a throttle drum (6) is attached to a left end (5c) of the throttle valve shaft (5), first and second fuel supply bodies (10,11) including first and second fuel injection valves (J1,J2) are arranged respectively in one side (B) and the other side (A) of the throttle bodies, both the fuel supply bodies (10,11) are connected by a fuel communicating path (16).
摘要:
An activation control device for an airbag device decreases the management costs by generalization of satellite sensors. There is provided at least one impact detection section disposed at a predetermined position of a vehicle, which detects a degree of shock applied to the vehicle; and a main control section connected to the impact detection section by communication, which determines a collision state based on an output signal of the impact detection section received from the impact detection section, and controls activation of the airbag device installed in the vehicle. The impact detection section receives and stores threshold data relating to a detected degree of shock, from the main control section, and controls transmission of an output signal to the main control section based on the stored threshold data. The main control section stores predetermined threshold data corresponding to each impact detection section disposed in the vehicle; and transmits the stored threshold data to the corresponding impact detection section.

A positioning apparatus according to the present invention includes a brushless motor, a positioning mechanism to position a movable member within a predetermined movable range in accordance with rotation of the brushless motor, and a motor control circuit to rotate a rotor of the brushless motor by sequentially supplying a driving pulse to a plurality of fixed coils of the brushless motor. The motor control circuit includes, a driving pulse generator to generate the driving pulse, a present stage number detector to detect a present stage number of the rotor in accordance with an output signal from a magneto-sensitive device of the brushless motor, an initializer to move the movable member to at least a forward traveling limit or a backward traveling limit within the movable range so as to set the rotor present stage number as a forward traveling limit stage number or a backward traveling stage number when the movable member reaches the forward traveling limit or the backward traveling limit, and a speed reducer to reduce a rotating speed of the brushless motor by reducing power of the driving pulse when the rotor present stage number is equal to at least the forward traveling limit stage number or the backward traveling stage number.
摘要:
An engine-driven portable generator using an inverter may still generate a voltage at its output terminals even though the engine is stopped. In view of this problem, the invention is to provide a portable generator, which is intended to prevent any residual voltage from generating between the output terminals. That is, a portable generator rectifying once an AC voltage into a DC voltage, converting the DC voltage into a single-phase AC voltage, and outputting the single-phase AC voltage, which has an output-stop-control unit (443) that, when an operating switch (305) is turned off, stops the operation of the inverter circuit at the timing when the voltage between the output terminals drops to 0, is provided.
