Probes, probe blades, tools for probe blades, blade holders, and probe systems for electrically testing a device under test (DUT). In some examples, the probe blades are configured to provide a Kelvin electrical connection with the DUT. In some examples, the probe blades include an alignment structure configured to engage with a blade holder when the probe blade is received within a blade-receiving region of the blade holder. The blade holders are configured to separably and operatively attach a probe blade to a probe system. In some examples, the blade holders include the probe blade. The probe systems are configured to electrically test the DUT and include the blade holder.

An object of the present invention is to effectively reduce vibration or noise caused by a motor. An inverter circuitgenerates an alternating current from a direct current supplied from a direct current power supplyby using a plurality of IGBTswhich are switching elements, supplies the generated alternating current to a motor, and drives the motor. This alternating current includes a fundamental harmonic current corresponding to a rotational speed of the motor, and a harmonic current of a switching operation of the IGBTs. A controllercontrols a second phase such that a first phase and the second phase are not superimposed on each other at a predetermined motor rotational speed, the first phase being a phase of an excitation force cyclically produced in the motorby the fundamental harmonic current, and the second phase being a phase of an excitation force cyclically produced in the motorby the harmonic current.

To reduce collision noise caused when an electromagnetic valve of a high-pressure fuel supply pump is opened. Therefore, in a control device for controlling a high-pressure fuel supply pump including: an anchor; a fixed core configured to attract the anchor with an electromagnetic force; a suction valve configured to be opened or closed when the anchor is sucked by the fixed core; and an electromagnetic force generation unit configured to generate the electromagnetic force when applied with a driving voltage, it can be achieved by providing a control unit configured to perform control to lower a driving current from a peak current before a timing at which the anchor is sucked by the fixed core and collides in an operation state where an engine is under no load and an engine rotation speed is equal to or less than a set rotation speed.

A control method of a fuel supply pump includes moving an anchor in the closing valve direction by passing a maximum drive current through the solenoid, and thereafter holding the anchor at a closing valve position by passing a holding current for keeping a closing valve state through the solenoid. The holding current is smaller than the maximum drive current. A current value of a first drive current is smaller than a current value of the holding current. A current value of a second drive current overlaps a range of the current value of the holding current. A current value of a third driving current is equal to or more than the current value of the holding current.

Vertical probe heads having a space transformer laterally tiled into several sections are provided. This change relative to conventional approaches improves manufacturing yield. These probe heads can include metal ground planes, and in embodiments where the ground planes are provided as separate metal plates parallel to the guide plates, the metal plates can also be laterally tiled into several sections. Such tiling of metal plates improves manufacturing yield and alleviates thermal mismatch issues. Probes are not mechanically connected to the space transformer, which facilitates replacement of individual probes of an array.

A problem of the present invention is to provide a vibration analysis program capable of analyzing bidirectional exchanges between a distribution amount and a difference amount with respect to an external system of the part in a part modeled as a finite element, in which the difference amount accumulation characteristic and the distribution amount accumulation characteristic are distributed. A vibration analysis program of the present invention includes a first stepof importing a finite element model of a target part modeled by a finite element method programto calculate an accumulation characteristic matrix and connection matrix, a second stepof calculating a difference amount-distribution amount mode matrix and eigenvectors after inputtingan attenuation characteristic to the accumulation characteristic matrix or the connection matrix as necessary, and a third stepof importing an input difference amount-flow amount vector to a target part obtained from an external system simulator, performing a mode coordinate transformation of the input difference amount-flow amount vector, calculating the mode vector response, and performing physical coordinate transformation of mode vector.

A power tool which has an anvilthat is rotated by a hammerand is housed in a housing, and rotates an output shaftis provided. The anviland the output shaftare integrally formed into one unit, and a carrierthat is rotatable relative to the anvilby a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil, a relief surfaceis formed. Cut-out portionsare formed at positions opposed to each other of a carrier, and by allowing an engaging pinto be interposed therein, a locking mechanism that limits the relative rotation between the anviland a lock ringis prepared. When the tool main body is manually rotated while the hammeris being stopped, the engaging pinlimits the relative rotation between the anviland the lock ring. The locked state between the anviland the lock ringis released immediately when the rotation of the motoris started.

The purpose of the present invention is to swiftly start up an engine in a range in which electrical equipment having electric power supplied thereto by a battery is not reset, even in cases when the battery is insufficiently charged and the battery is deteriorated. An engine start-up device according to the present invention starts up an engine by transmitting, to the engine, the rotary force of a direct-current motor driven by a battery. The engine start-up device is provided with: a battery-voltage acquisition unit for acquiring the battery voltage of the battery; a target-current-value calculation unit which calculates, on the basis of the battery voltage acquired by the battery-voltage acquisition unit, a target current value for a motor current to be supplied from the battery to the direct-current motor; and a motor-current control unit for controlling a switching element which is connected to the direct-current motor, and through which the motor current flows, such that the motor-current value of the motor current approaches the target current value.

A communication terminal displays thumbnails for predetermined-region images in a panoramic image and accepts a selection of a predetermined thumbnail so as to display the predetermined-region image corresponding to the accepted thumbnail. This brings about an effect that a user can easily find a desired panoramic image or a desired predetermined-region image in the panoramic image.
