摘要:
An outer case connector portion, a gauge housing case, and the like for use with a pressure sensor, for example, are generally made of a thermoplastic or thermosetting resin. However, the resin physically causes curing shrinkage. Especially when a metal is insert molded with a resin, curing shrinkage of the resin generates a gap at the interface between the resin and the metal. By filling an anaerobic, high-permeability adhesive in the gap, hermetic sealing can be ensured and reliability can be enhanced. Inexpensive hermetic sealing and enhanced reliability are realized.
摘要:
After the periphery of the magnetic sensitive element is surrounded by an elastic member, the magnetic sensitive element is mold-formed with resin material. Soft epoxy or gel resin is employed as the elastic member, poured in an element-mounting space and solidified. The magnetic sensitive element is surrounded by silicone rubber. Such construction allows the magnetic sensitive element not to be affected by vibration and allows the elastic member to absorb the stress which is created due to the thermal deformation of the molded resin.

The present invention provides a pressure detector capable of easily responding to changes in specification. The pressure detector has a sensor unit for detecting pressure and electronic parts for reducing electrical disturbance which are electrically joined to an exposed part of lead material of an opening of an external case. Thermoset resin is injected and set in the opening to obtain fixed members. An external electronic part for compensating for transient voltage resistance and electromagnetic failure resistance of a single one-chip semiconductor sensor can be mounted, and cost can be reduced by miniaturization, light weight, and reduction in man-hours required for assembly.

摘要:
An electronic device requires an electronic component to be mounted for the purpose of static shielding. The mounting of such an electronic component raises a problem of avoiding thermal stresses and cracks generated due to the difference between the coefficients of linear expansion of component materials. A positioning recess, a joining-substance thickness ensuring recess, a joining-substance thickness ensuring projection, etc. are formed in a combined manner in an electronic component mount portion of each of leads, whereby spreading of cracks generated in the joining substance can be suppressed and reliability can be improved. Filling a sealing material so as to seal and restrain the electronic component mounted in the electronic component mount portion without leaving voids contributes to further suppressing spreading of cracks generated in the joining substance and ensuring more improved reliability of the joining substance.

The invention is intended to provide a small and highly reliable pressure sensor, which has a smaller number of components and can be produced by using a mold for resin molding in common. A sensor unit (11) is molded with resin and includes a semiconductor chip (1) for converting the change in pressure of a medium introduced through an introduction hole for measurement into an electric signal. A lead member (12) has one end exposed in a connector (23) and is electrically connected to the semiconductor chip (1) in the sensor unit (11) beforehand. Pressure is applied to the semiconductor chip (1) through a pipe (22). An outer case (21) is integrally formed of synthetic resin by insert molding of the sensor unit (11), the lead member (12) and the pipe (22).

摘要:
A probe cleaning apparatus includes a cleaning-conditions database. The probe cleaning apparatus removes contamination from a probe by irradiating the probe by a laser beam, refers to the cleaning-conditions database based on information about the probe, such as material and shape, and controls properties of the laser beam, such as output intensity, pulse interval, wavelength, and pulse width, so that the probe cleaning apparatus removes the contamination from the probe without damaging the probe by heat.
