Disclosed herein is a device that includes a capacitor, a pumping circuit supplying a pumping signal changed between first and second potential to a first electrode of the capacitor, and an output circuit precharging a second electrode of the capacitor to a third potential different from the first and second potentials. The second electrode of the capacitor is thereby changed from the third potential to a fourth potential higher than the third potential when the pumping signal is changed from the first potential to the second potential.

Eyewear comprising a frame and a liquid storage portion that is disposed within the frame and that includes a cavity for storing liquid. The liquid storage portion includes a gas passing section that allows gas to pass therethrough from the cavity to an inside surface of the frame, which is a surface facing a head of a wearer when the frame is worn on the head, but does not allow liquid to pass therethrough from the cavity to the inside surface of the frame. The liquid storage portion may be disposed such that an outer surface of the liquid storage portion is further inside the frame than an outer surface of the frame.

摘要:
An abnormality detection apparatus for a multi-cylinder internal combustion engine changes a fuel injection quantity of a predetermined target cylinder to detect an abnormality of an internal combustion engine based on values of rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity. The abnormality detection apparatus corrects the values of the rotational variations relating to the target cylinder detected before and after the change of the fuel injection quantity based on at least one of the number of revolutions of the engine and an engine load at a corresponding detection time.
摘要:
An apparatus for detecting imbalance abnormality in an air-fuel ratio between cylinders in a multi-cylinder internal combustion engine according to the present invention increases a fuel injection quantity to a predetermined target cylinder to detect imbalance abnormality in an air-fuel ratio between cylinders at least based upon a rotation variation of the target cylinder after increasing the fuel injection quantity. The increase in the fuel injection quantity is carried out in the middle of performing the post-fuel-cut rich control. Since timing of the post-fuel cut rich control is used to increase the fuel injection quantity, the exhaust emission deterioration due to abnormality detection execution can be prevented as much as possible.

A semiconductor device prevents the OFF current of a complementary field effect transistor from varying with changes in ambient temperature. The semiconductor device includes: a substrate voltage generating circuit that generates the substrate voltage of an n-channel MOS transistor forming a CMOS; a replica transistor that is a replica of the n-channel MOS transistor, and is diode-connected; and a voltage applier that applies a voltage of a predetermined voltage value between the anode and cathode of the replica transistor. In this semiconductor device, the substrate voltage of the replica transistor is the substrate voltage generated by the substrate voltage generating circuit. The substrate voltage generating circuit controls the substrate voltage to be generated so that the current value of the current flowing into the replica transistor becomes equal to a given target value.
摘要:
Since both a physical storage place and a logical storage place in a storage system are separately managed as a directory structure, or a hierarchical structure, even in such a case that the physical storage place has been changed, the logical storage place which is displayed to the user is not changed, and thus, the user can use the file while the user need not become aware of the change of the file. When the contents of a file is displayed, a physical storage destination of the file is acquired based upon both a reference path and a relative path of the file, and then, the file is acquired from the physical storage destination.

A varistor having a favorable heat-dissipating property is provided.In the varistor, a composite part having a favorable heat-dissipating property formed by a composite material composed of ZnO and Ag is arranged between main faces of a varistor matrix. Therefore, the heat transmitted from a semiconductor light-emitting device to a varistor part through an outer electrode can rapidly be transferred toward a main face on the opposite side through the composite part. In this varistor, side faces excluding inner side faces are exposed at side faces of the varistor matrix. Such a structure yields a favorable heat-dissipating property.
