Abstract: A fuel supply device, which is mounted on a fuel tank, includes a lid member that covers an opening of the fuel tank, arm members mounted on the lid member, and a component mounted on the lid member via the arm members. The arm members and the component have an engaging structure which engages each other by elastic deformation of the arm members. The arm members are made of a resin material having a higher elastic modulus than the resin material forming the lid member.

Abstract: A fuel supply device includes a flange, a pump unit, a supporting pillar, and a boss. The flange is attached to an opening portion of a fuel tank. The supporting pillar supports a sub tank such that the sub tank is positioned closer to and away from the flange. The boss is fixed at the flange and an end of the supporting pillar is inserted into the boss. The boss is made of a material different from that of the flange. The boss includes a stress concentration portion that is preferentially broken when a force equal to or greater than a predetermined value is applied to an end portion of the supporting pillar in an axis perpendicular direction.

Abstract: A fuel supply device is provided with a tank lid closing a through-hole in a tank wall of a fuel tank and sends fuel in the fuel tank to an outside of the fuel tank when fixed to the fuel tank by interposing the tank lid between the tank wall and a fixing member. The tank lid has a lid-side contact surface portion which is in an exposed outer surface exposed outside the fuel tank and is in contact with a fixed-side contact surface portion of the fixing member screwed into the tank wall along an outer circumferential portion of the tank lid. The lid-side contact surface portion is provided with an acid-resistant coating film set with surface free energy different from surface free energy set to the fixed-side contact surface portion.

Abstract: A fuel supply device includes a relief valve, a pressure regulator, and a controller. The controller controls a first pump to send fuel into an engine through a first passage, and controls a second pump to send fuel into a second passage to communicate with the first passage.

The pressure regulator discharges fuel when a fuel pressure of fuel chamber is higher than a regulation pressure higher than the relief pressure in a state that a fuel pressure of backpressure chamber is equal to the relief pressure.

Abstract: A motor includes a rotor, a commutator, a brush, and a bias member. The commutator has a rectifying surface. The commutator rectifies an electric current supplied to the rotor through the rectifying surface. The rotor is rotated by being supplied with the electric current. The brush makes contact with the commutator via the rectifying surface. The rotor is supplied with the electric current through the brush. The brush starts making contact with the commutator on an entry side of the brush as the rotor and the commutator rotate with respect to the brush along a rotative direction and the commutator intermittently makes contact with the brush. The bias member biases the brush toward the entry side.

Abstract: In a fuel supply system, a fuel pump supplies fuel from a fuel tank to a fuel supply piping and to a back pressure introducing passage. A pressure regulator has a fuel pressure regulating chamber communicated to the fuel supply piping, and a back pressure chamber communicated to the back pressure introducing passage. When a fuel pressure in the fuel pressure regulating chamber is larger than a relief pressure that bulges the diaphragm toward the back pressure chamber, a relief valve opens a relief port to return the fuel from the fuel pressure regulating chamber to the fuel tank. The relief pressure is adjusted by controlling a fuel pressure in the back pressure chamber of the pressure regulator.

Abstract: An image pickup apparatus comprises an image pickup device (e.g., a lens, a CCD) for picking up an image of an object, a shutter button having a magnetic member thereunder, an XY-axes geomagnetic sensor, a decoder for decoding an output of the XY-axes geomagnetic sensor to produce a bearing angle and an inclined angle based on a horizontal plane, a viewfinder display for displaying the bearing angle and inclined angle on the screen of a viewfinder. When the user presses the shutter button, the magnetic member approaches the geomagnetic sensor, so that a relatively large magnetic field (1 Oe) is applied to the geomagnetic sensor, and the image pickup device is controlled to perform an image pickup operation. It is possible to further incorporate a memory (e.g., ROM) for storing relationships between the geomagnetism, bearing angle, and inclined angle with respect to a prescribed terrestrial location.

Abstract: A cellular phone places a call to vehicle navigation apparatus, performs ID matching, and acquires the information on the position of the vehicle measured by the vehicle navigation apparatus. The cellular phone acquires peripheral map data including the position of the owner of the vehicle and the position of the vehicle where the vehicle navigation apparatus is mounted from a position information center and displays the data acquired together with the data on the positions.
