    摘要： A low temperature sintering ceramic material, having low temperature sinterability and excellent thermal conductivity, is particularly suitable for use in making an IC substrate of a ceramic printed plate board. This low temperature sintering ceramic material has two composition types. One is a binary composition type ceramic material consisting essentially of MgO and B.sub.2 O.sub.3, and the other is a ternary composition type ceramic material composed of principal components consisting of MgO and B.sub.2 O.sub.3 and assisting components consisting of one or more selected from Li.sub.2 O, Na.sub.2 O, K.sub.2 O, a fluoride of an alkali metal and a fluoride of an alkaline earth metal. After sintering, MgO and B.sub.2 O.sub.3 are respectively contained at 50 to 90 mol% and 10 to 50 mol% on 100 mol% of the total amount of MgO and B.sub.2 O.sub.3.

In this ceramic heater, which is capable of being cantilevered, two electrode portions are provided on a single straight or curved line and heat generating portion is positioned on one side of said line. The heat generating portion comprises a ring-like portion and two leg portions integrally connected to the ring-like portion at two connecting portions which approximately bisect the ring-like portion. The two electrode portions are provided at fore ends of the leg portions respectively, and the ring-like portion and the two electrode portions conjointly form a triangle.

    摘要： A ceramic heater body is formed in a plate shape, and has electrode attaching portions at both ends of the heater body. A plurality of openings are formed in the electrode attaching portion, and a metallized layer is formed on the inner peripheral surface of each of the openings. Electrodes having a plurality of wires are connected to the electrode attaching portions, for supplying power to the heater body. The metal wires are inserted into the openings formed having the metallized layers on the inner peripheral surfaces, and are secured by brazing to the metallized layers. The diameter of the metal wire is set to 0.5 to 3 mm, and the metal wires are buried in the openings, at a depth of 1 to 5 mm.

    摘要： A scanning apparatus includes a mirror coupled to a base via a spring portion, and a light source for emitting a beam toward a reflecting surface of the mirror so that the beam is incident thereon. The mirror reflects the beam from the light source and rotationally swings under a resilient force of the spring portion when a force is applied thereto. The reflecting surface of the mirror includes a plurality of mirror surfaces at different angles. The beam from the light source is simultaneously reflected by the mirror surfaces at different angles.

    摘要： A plurality of grooves, each having a depth of 10 &mgr;m or more and arranged adjacent to each other, are formed at a predetermined portion of a semiconductor substrate where a passive element is formed. Then, a thermal oxidation treatment is performed to let an oxide film grow from an inside surface of each groove so as to fill an inside space of the groove with a thermal oxide film thus grown and turn an entire portion intervening between adjacent grooves into a thermal oxide layer. Each groove has a width of 1 &mgr;m or less, and a width of a semiconductor material intervening between two adjacent grooves is 81.8% or more with respect to the groove width.
