A signal input circuit includes: a signal input device having a signal input terminal; an inspection capacitor connected between the signal input terminal and a reference potential; a connection unit connecting/disconnecting an inspection path between the inspection capacitor and the signal input terminal; a charge and discharge unit charging/discharging the inspection capacitor; and a determination processing unit carrying out a terminal failure detection processing. The determination processing unit controls the connection unit to disconnect the inspection path and controls the charge and discharge unit to set the voltage of the inspection capacitor to a terminal inspection voltage in a charge and discharge procedure, controls the connection unit to connect the inspection path in a continuity establishing procedure, and detects the terminal failure at the signal input terminal or a communication path from the signal input terminal based on a voltage of the inspection path.

A method of adjusting a rotary machine includes the steps of press fitting an adjustable member to one of a housing and a rotary body where the adjustable member is arranged to a reference position at which movable amount or a rotary body is zero, and adjusting the movable amount of the rotary body in a direction of a rotary axis to the predetermined amount by varying a position of the adjustable member that is press-fitted to the one of the housing and the rotary body from the reference position by the predetermined amount in a direction in which the movement restricting part and the contacting part contacting with each other are separated from each other.

The present invention provides a fastening tool in which even when two members are inclined as the members are threadedly inserted, a displacement load is not applied to the members almost at all. A fastening bolt 1 of the fastening tool includes a rod-like bolt body 10 provided at its outer periphery with a male thread 11, and a head 20 provided on an end of the bolt body 10 and having a diameter greater than that of the bolt body 10. A lower surface of the head 20 is a tapered surface whose diameter is reduced toward the bolt body 10 so that the lower surface abuts against a tapered seat surface 31 of the first member 3 provided with a bolt through hole 31. This tapered surface is formed into a tapered curved surface 21 finished into a curved surface. With this structure, even if the threaded hole 40 of the second member 4 into which the fastening bolt 1 is threadedly inserted is inclined, the tapered curved surface 21 appropriately slides on the tapered seat surface 31 in the first member 3, the threadedly insertion direction of the bolt body 10 substantially matches with the axial direction of the threaded hole 40. Therefore, the fastening bolt 1 can easily enter concentrically with the threaded hole 40.

A device and method can carry out reliable visceral 3-D input over a wide range at arbitrary measuring time intervals without being affected from electric field or temperature, with requiring small installation space. A bright spot is displayed on the display surface of a display by scanning. A photo device condenses the bright spot on the display to project the spot light onto the projection plane, thereby projecting it onto photo detectors the projection plane. A counter counts the time from the time of a vertical sync signal, and supplies its output to AND gates. A correspondence detector brings bright spot display positions on the display at multiple times into correspondence with their projection positions on the photo device in accordance to recording time. An extrinsic parameter calculator calculates the 3-D translation and rotation of the photo device with respect to the bright spot scanning surface of the display from at least three sets of the bright spot display positions and their corresponding projection positions.
摘要:
A fuel injection system for an internal combustion engine having intake valves, a plurality of fuel injection valves, and a control unit for determining the fuel injection time and fuel injection duration. The system comprises an ignition pulse generating circuit and computing circuit for producing a fuel injection time delay signal, representing a delay after ignition time, and a circuit for decreasing the time delay with an increase of the engine speed. A maximum time delay is selected to inject fuel after the intake valves of the engine have closed.
