A glass substrate has a pair of main surfaces opposite to each other. Two island-shaped portions made of silicon are buried in the glass substrate. The two island-shaped portions are exposed from the two main surfaces of the glass substrate, respectively. An electrode is formed on one main surface of the glass substrate so as to be electrically connected to one exposed portion of one island-shaped portion, and another electrode is formed thereon so as to be electrically connected to one exposed portion of the other island-shaped portion. Still another electrode is formed on the other main surface of the glass substrate so as to be electrically connected to the other exposed portion of the one island-shaped portion. A silicon substrate having a pressure sensing diaphragm is bonded to the other main surface of the glass substrate.

A load sensor is assembled by screwing a nut on a bolt, sequentially fitting a washer and a tube spacer on the bolt, fitting a bore of a strain-generating member on the tube spacer, fitting another washer on the bolt, tightening another nut, and clamping a bobbin-shaped unit composed of the washers and the tube spacer between the nuts in the axial direction of the bolt. Since the strain-generating member having a thickness less than the height of a strain-generating member holding space formed between the washers is placed in the space with some clearance, even when the washers are fixed to the bolt by a strong pressing force, the pressing force will not directly act on the strain-generating member.

Load sensor equipped with strain-generating member having strain elements with tube spacer for eliminating clamping force

A load sensor is provided, which prevents defective printing of strain-sensing elements caused by the deflection of a pressure-receiving portion and provides stabilized quality and fabrication yields. The load sensor is provided with the strain-sensing elements printed on the pressure-receiving portion. The tip portion of the strain generating portions having a loading point is allowed to stay in advance below the plane containing the print surface of the strain generating portions in the direction of thickness. The tip portion of the pressure-receiving portion will never stay above the print surface of the strain generating portions even when the pressure-receiving portion is deflected in the heating process during fabrication. Therefore, this makes it possible to avoid defective printing of the strain-sensing elements caused by the deflection of the pressure-receiving portion.

A pin contact of a connector and a method of fabricating the pin contact which enables a substantial decrease of manufacturing cost, and smooth installation of the pin connector without a change in the pitch of arrangement at the time of press-fitting into a pin housing. A flat metal sheet undergoes blanking and pressing to form a narrow piece including a strip portion of decreased area of a fracture. Then an approximately L-shaped connecting portion is bent at right angles to raise the narrow piece sideways. Thereafter the strip portion of the narrow piece is pressed along the direction of rising, to thereby form an approximately cylindrical contact section. A raised piece at the rear of the contact section is provided with a locking section which faces approximately at right angles with the direction of arrangement.
