摘要： A disposable pressure transducer for measuring fluid pressure, which includes a sensor assembly in a housing. The housing includes a fluid chamber and a sensor-accommodating chamber which are formed integrally with each other. The sensor assembly comprises: a sensor chip for converting pressure into an electrical signal; an insulating board on which the sensor chip is mounted and which is provided with an integrated-circuit for processisng an output signal of the sensor chip so that an external measuring device can read the signal; a cylindrical coupling lid which is bonded to the board in such a manner as to surround the sensor chip and which is fitted into a communication through-hole which provides communication between the fluid chamber and the sensor-accommodating chamber of the housing; a pressure-transmitting medium charged into the interior of the coupling lid so as to provide electrical insulation between the fluid chamber and the sensor chip; and an electrical cable connected to the board and electrically connected to the external measuring device.

摘要： A metal body having a very large surface area and high porosity, useful as a gasoline vaporizer, a heat exchanger for automobiles, a catalyst or catalyst carrier, a filter, or the like, and composed of a plurality of metal fibers which are entangled with one another to form a bed or stratum, the metal fibers being coated with a metal in such manner that the stratum provides rough and complex surfaces with cracks and irregularities. The invention also includes a process for making said metal body including the steps of entangling metal fibers to form a bed, placing the bed of fibers in contact with a coating metal, heating the fiber bed and coating metal so as to wet the fibers with molten coating metal, and cooling.

摘要： A catheter tip pressure transducer for detecting the pressure in various portions of a living body accurately and safely comprises a pressure sensor disposed within the end portion of a catheter. The pressure sensor comprises a pressure sensitive diaphragm whereon strain gauges are formed by a diffusion method. The pressure sensor is mounted on an insulated supporting member without being secured firmly thereto. A protecting member made of silicone rubber fills the hollow portion of the catheter so as to isolate and protect the pressure sensor and the ambient body tissue.Pressure is accurately measured by the pressure sensor without being influenced by the thermal stresses which occur in the supporting member. Furthermore, electrical isolation and mechanical safety are obtained.

摘要： An intracranial pressure transducer includes a casing comprising an annular member having a screwed part on an outer wall thereof for fitting and securing a skull of a body. A pressure-electric transducing portion including a supporting member which is inserted within an inner wall of the casing and is tightly fixed to the predetermined upper portion from a tip portion of the casing, an indicating circuit for indicating the intracranial pressure in response to an output of strain sensitive elements, and indicating means. The intracranial pressure transducer converts intracranial pressure of a cerebrospinal fluid to the internal pressure of a pressure receiving layer of the transducer by the copanar Coplanar method which maintains the dura to be coplanar by the depression of the pressure receiving layer of the transducer against the dura, applies internal pressure of the pressure receiving layer to a strain sensing member, supplies an electrical signal by a strain sensitive element in response to the internal pressure of the pressure receiving layer, and accurately and safely indicates the intracranial pressure on the indicating means.
