摘要： A sensor module includes: a diaphragm including a first region and a second region that includes a position at which a strain ε that occurs by an effect of a physical quantity caused by a measurement target fluid is zero and has a smaller effect of the physical quantity caused by the measurement target fluid than the first region; strain detecting elements disposed in the first region; and an electric conductor that is at least partially disposed in the second region and electrically couples the strain detecting elements to each other to configure a bridge circuit. The electric conductor includes a resistance adjuster, at a position corresponding to the second region, that adjusts a resistance of the electric conductor.

摘要： A pressure detector includes a first board with a first pressure inlet, a first groove, and a first board electrode; a second board with a second pressure inlet, a second groove, and a second board electrode; and a sensing unit arranged therebetween with a diaphragm. The first groove is in communication with the first pressure inlet so as to prevent the formation of a closed space between the first board and the diaphragm when they contact with each other. The second groove is in communication with the second pressure inlet so as to prevent the formation of a closed space between the second board and the diaphragm when they contact each other.

摘要： An optical sensor includes a tube-shaped base formed from a metal, an optical fiber member received inside the base, and a sensor head formed from monocrystalline alumina and bonded to the base to be optically connected with the optical fiber member. The sensor head is provided with a first cavity including a first reflection surface configured to reflect a part of light introduced through the optical fiber member and a second reflection surface provided facing the first reflection surface and configured to reflect a part of the light reflected by the first reflection surface. A first interference light produced by an interference between the light reflected by the first reflection surface and the light reflected by the second reflection surface is output from the first cavity.

摘要： A circuit board including an electronic circuit unit and electronic adjusting units is disposed in a case. A signal transmitting member connected to the circuit board is mounted in a mount hole of a cover member. Operation holes corresponding to a plurality of operable portions of the electronic adjusting units are provided to the cover member. A cap member including a plurality of cap bodies and a connection portion connecting the cap bodies is attached to the cover member to close the operation holes. The operation holes for adjusting the electronic adjusting units are thus covered/uncovered by the simple cap member. The operation holes are reliably waterproofed by the cap member.

摘要： A pressure sensor includes: a pressure sensor element; an adapter integrally attached to the pressure sensor element and defining therein a hole where a pressure of a fluid to be measured is introduced to the pressure sensor element; a fitting member having a housing recess housing the adapter and connectable to a connected member; and a pressing member pressing a valve of the connected member and defining a communicating path through which a flow path where the pressure of the fluid is introduced is in communication with the hole of the adapter. The fitting member is made of a synthetic resin. An O-ring is interposed between a circumferential surface of the adapter and the fitting member. The adapter is a synthetic resin member, and includes a contact portion brought into contact with the adapter and a pressing portion pressing the valve. The pressing member is welded to the fitting member.

摘要： For producing a three-dimensional circuit component, an electronic component is mounted on a synthetic resin block. A plurality of electrically-conductive patterns used to establish an electrical connection to the electronic component are formed on the block along a three-dimensional shape of the block. An end of each electrically-conductive patterns is provided with a solder-disposed section. A solder is provided between the solder-disposed section and an opposed surface of the electronic component. The section of each electrically-conductive patterns other than the solder-disposed section and a section on which the electronic component is mounted is internally formed in the block. Since the section of each electrically-conductive patterns other than the section on which the electronic component is mounted is internally formed in the block, the electrically-conductive patterns are not unnecessarily exposed.

摘要： A physical quantity sensor includes two substrates and a movable electrode that is disposed between the two substrates and is bonded to the two substrates. In the physical quantity sensor, the movable electrode has an elastically deformable diaphragm and one of the two substrates is an electrode substrate having a detection electrode on a detection surface opposite to the diaphragm to detect capacitance between the diaphragm and the detection electrode. In the physical quantity sensor, in a range between a room temperature and a bonding temperature when the two substrates and the movable electrode are bonded, coefficients of thermal expansion of the two substrates are smaller than that of the movable electrode and in a temperature range where the physical quantity sensor is used, a coefficient of thermal expansion of the movable electrode is between a first and second substrates.
