A piezoelectric vibrator has an airtight terminal comprised of a lead terminal and a piezoelectric member. The lead terminal has an inner lead portion and an outer lead portion. The piezoelectric member has an exciting electrode and a mount electrode disposed on a surface of the piezoelectric member. A plasma arc electrode is connected to a power supply for generating a plasma arc discharge. To bond together the inner lead portion of the lead terminal to the mount electrode of the piezoelectric member, the outer lead portion is connected to an output terminal of the power supply and the plasma arc electrode is positioned at a vicinity of a bonding portion for bonding together the inner lead portion and the mount electrode. A voltage is applied between the inner lead portion and the plasma arc electrode to generate a plasma arc discharge. The generated plasma arc is discharged to the bonding portion while subjecting at least the bonding portion to an argon gas atmosphere to thereby bond together with a solder the inner lead portion and the mount electrode.

The present invention provides an oxygen concentration control apparatus for an incubator and an incubator using the same also suitable for continuous use for a long period. A pulse oximeter measures percutaneous arterial oxygen saturation (SpO2) of a newborn accommodated in an incubator, and a control unit obtains fraction of inspired oxygen (FiO2) used for setting the measured value of the percutaneous arterial oxygen saturation (SpO2) obtained by the pulse oximeter to a predetermined set value. In the measurement of the percutaneous arterial oxygen saturation (SpO2) by the pulse oximeter, it is unnecessary to warm the skin of a region to be measured. Consequently, even if the percutaneous arterial oxygen saturation (SpO2) is measured continuously for a long period, there is low possibility that the accommodated newborn suffers a cold burn.

In a wire harness-arranging method, a wire group at a predetermined portion of a wire harness, comprising a plurality of wires bundled together, is untied, and is arranged so as to be coated with a water stop agent. The wire harness is supported above an installation plate through a plurality of wire group support jigs mounted upright on the installation plate, in spaced relation to this installation plate. Subsequently, U-shaped wire holding members, each having a slit of a uniform width over an entire length thereof, are brought respectively into gripping engagement with those portions of the wire group, disposed respectively at opposite ends of the predetermined portion of the wire harness spaced from each other in a wire-installing direction, from an upper side of the installation plate, so that the wire group at the predetermined portion is arranged along each of the slits in an upward-downward direction.

The present invention provides a test circuit configuration technology suitable for use in a semiconductor device, which is capable of testing the semiconductor device without using a commercially-available tester (test device) and is less reduced in required cost. A test program related to a semiconductor device to be tested, which is described in tester language, is analyzed. Components of a test circuit (ALPG), corresponding to the contents of each test to be carried out are extracted, i.e., unwanted or unnecessary components are deleted to thereby generate the description (test circuit architecture construction data) of a circuit capable of conducting tests in desired test units according to HDL (Hardware Description Language).
摘要:
A grommet (10) has a small diameter drum portion (11), a large diameter drum portion (15) and a lip portion (19). A fitting groove (15d) which is fitted into a through hole of a panel is provided on an outer wall surface (15a). The lip portion (19) protrudes to an outer side of the outer wall surface (15a) of the large diameter drum portion (15) so as to contact closely with the panel (9). In the grommet (10), a rear surface side of the large diameter drum portion (15) is thin. Due to a thin-wall portion (15c) which is formed by thinning the rear surface side of the large diameter drum portion (15), upon opening a molding die (30), the lip portion (19) with a large undercut amount elastically deforms to a side of the thin-wall portion (15c). As a result, the grommet (10) can be easily released.

In a system managing method and apparatus, a load applied to a common processing unit is decreased so as to improve a managing ability of the system. The system managing apparatus manages a system having a plurality of interfaces including a managed object interface and a non-managed object interface, the managed object interface handling resources as managed objects, the non-managed object interface handling resources as non-managed objects. A common processing unit performs operations common to the plurality of interfaces. A managed object interface agent is connected to the managed object interface so as to manage pointer attributes independently of the common processing unit. A non-managed object interface agent is connected to the non-managed object interface. The managed object interface agent includes a knowledge database and an agent database. The knowledge database stores information regarding a pointing instance and a pointed instance defined in each pointer attribute. The agent database holds the resources as instances of the managed object type so as to delete, add or update a value of each pointer attribute according to a process request.
摘要:
A magnetic oxygen analyzer which employes a detector comprising a magnetic pole, heat generator arranged in a non-uniform magnetic field where the intensity of a magnetic field produced by the magnetic pole varies, and a magnetic wind sensor disposed to not be affected by heat produced by the heat generator. A change in electrical resistance of the sensor, caused by change in magnetic wind strength, is detected as the oxygen concentration of a mixed gas. The magnetic wind is caused by the magnetic field produced by the magnetic pole and by heat produced by the heater and is related to the oxygen concentration of the mixed gas exposed to the analyzer. Advantageously, the analyzer of the invention provides improved signal to noise ratio, is immune to ambient temperature, and eliminates the need for precise temperature control.

A test circuit is provided on a probe card or a wafer on which semiconductor chips to be tested are formed. The test circuit and each of the semiconductor chips to be tested are electrically connected to each other to perform testing, whereby the test can be carried out without using a tester. Conducting a test in such a wafer stage within an aging device allows the simplification or omission of a test subsequent to packaging.
