    摘要： A ceramic heater that may be used in an oxygen sensor for automotive air-fuel ratio control systems and includes a ceramic square rod formed with a laminate of a heater substrate on which a heater-patterned layer consisting of a heater element and leads is formed and a covering substrate covering the heater-patterned layer. Metallic terminals are connected electrically to the leads of the heater-patterned layer, respectively, and mounted on surfaces of the ceramic square rod opposed to each other in a direction of lamination of the heater substrate and the covering substrate, respectively. At least one outer lead is joined to one of the metallic terminals through a bonding layer.

    摘要： Several heater patterns are printed on a ceramic green sheet for substrates, and the ceramic green sheet is laminated with a ceramic green sheet for cover plates, thereby forming a lamination body. Then, the lamination body is cut so that it is divided into several intermediate bodies, each of which holds a corresponding one of the heater patterns therein and has a side surface on which a terminal portion of the heater pattern is exposed. Then, the intermediate body is baked. As a result, a ceramic heater composed of a heater substrate holding the heater pattern and a cover plate disposed on the heater substrate to cover the heater pattern can be provided without any micro-cracks therein.

    摘要： An ultrasonic test method for detecting a defective portion more precisely in a noncontact reflection way, and ultrasonic test instrument used for the method. An ultrasonic wave is transmitted from a transmitter (20 (21)) provided on one side of an object under test, and the reflected wave is received by a receiver (30 (31)) provided on the same side. The ultrasonic wave is transmitted/received through an air layer between the transmitter and the object (100) under test and between the receiver and the object (100). The relative positions of the transmitter (20), the receiver (30), and the object (100) are so determined that the air propagation time ta of the air path (RA) between the transmitter and the receiver is longer than the propagation time tb of the reflected wave in the reflection path (RB). The propagation of the ultrasonic wave through the solid body between the transmitter and the receiver is blocked. This invention is suitable to test laminated material (100) such as a laminate of CFRP (101) and insulation (102) in a noncontact way.

    摘要： An air side cover is attached to a proximal end of a housing so as to confine an aerial atmosphere therein. A measured gas side cover is attached to a distal end of the housing so as to confine a measured gas atmosphere therein. A glass sealing material airtightly seals a clearance between an inner surface of an insulator and an outer surface of a sensing element. A contact interface of the glass sealing material protrudes toward a proximal end of the gas sensor compared with at least an adjacent portion of the remainder of the glass sealing material. By melting and hardening a glass pellet, the sensing element is airtightly fixed in the insulator.

    摘要： An improved structure of a mechanical seal for keeping a gas chamber and a reference gas chamber airtight in a sensor body. A sensor element is disposed within an insulator. A gap between the sensor element and the insulator is sealed hermetically by a glass sealing member. The glass sealing member has a coefficient of thermal expansion whose differences between itself and the sensor element and the insulator is within a range of ±3×10−6/° C. This provides a mechanical seal required to keep the reference gas chamber and the gas chamber in the gas sensor airtight in an environment such as an automotive exhaust system subjected to a great temperature change.
