摘要:
An exothermic resistor for use in a hot wire air flow meter, having a wire (2) in the form of a coil made of a metal, a pair of lead wires (3) connected to connections (21) formed at the opposite ends of the coil, and a support member (4) which integrally supports the connections as well as the coil located between the connections. An example of the support member is in the form of a tubular cylinder closed at its both ends. The support member is formed from glass only or formed of a layer of a glass-ceramic-composite material. The hot wire air flow meter is designed to be easely mass-produced and to have improved transient response characteristics with respect to abrupt changes in the air flow rate.

A semiconductor chip module includes semiconductor chips each of which has contacts on its entire front face. A multi-layered organic circuit board having a small dielectric constant is provided for mounting the semiconductor chips. Intermediate ceramic substrates having the same thermal expansion coefficient as that of the semiconductor chip, are also provided. Each such intermediate ceramic substrate has contacts on its front and back faces corresponding to those of the semiconductor chip. These contacts are electrically connected directly in a one-to-one relationship. The contacts on the semiconductor chip and the corresponding ones on the front face of the intermediate ceramic substrates are connected by solder. The contacts on the back face of the intermediate ceramic substrate and the corresponding contacts on the front face of the multi-layered ceramic circuit board are connected by respective conductive pins having a predetermined flexibility and rigidity through a predetermined gap therebetween. With this arrangement, the relative displacement due to a thermal expansion difference between the intermediate ceramic substrate and the multi-layered organic circuit board is permitted without causing substantial stress thereon.

A radial tire with a split structure in the first belt layer provided with an organic fiber cord layer in the split structure and having a narrow groove extending in the circumferential direction of the tire and provided in each of both shoulder portions of the surface of a tread, wherein the narrow groove has a depth h determined in the radial direction of the tire, and a distance d.sub.1 measured between the internal edge on the shoulder side of an opening portion of the narrow groove and the radially outermost surface of the shoulder portion as determined along a parallel line to the surface of the tread, and a distance d.sub.2 measured between the internal wall surface on the shoulder side of the bottom of the narrow groove and the radially outermost surface of the shoulder portion as determined along a parallel line to the surface of the tread, wherein d.sub.1 is less than 15 mm and is smaller than d.sub.2, and a shape factor m defined by the following equation is 0.8 to 1.2: ##EQU1##
摘要:
A method of manufacturing a magnetic head includes fabricating a magnetic block having a lamination of magnetic alloy films and nonmagnetic substrates, and cutting the magnetic block into two bars to obtain magnetic core halves. A nonmagnetic film is formed on a surface of each of the core halves. The core halves are joined by adjoining the surfaces having the nonmagnetic film and then heating the thus adjoined core halves. Additionally, a magnetic field is applied rotating in a plane parallel to a plane of the magnetic alloy films. The joined core halves is then cut into a specified width, and a wire-winding window is machined therein.

An improvement in the structure of the belt portion of a heavy duty radial tire for use in trucks, large-size buses, small-sized trucks, etc., and more particularly, a heavy duty pneumatic radial tire improved with respect to the driving stability under heavy duty conditions while ensuring the durability of the tire (belt portion) during high speed running through the provision of at least three belt layers between the tread surface and the carcass layer of the tire and the specification of the relationships between the angles of the cords constituting these plurality of belt layers.
摘要:
A perpendicular magnetic head of high recording and reproducing efficiency which integrally incorporates a step-up transformer. A main pole for picking up a reproduce magnetic flux from a recording medium and applying recording magnetic field thereto is formed of a magnetic thin film. A signal winding formed of a thin film is disposed in the immediate vicinity of the forward end of the main pole so as to have a high conversion sensitivity per turn with respect to the reproduce magnetic flux from the recording medium. The signal winding which itself constitutes a closed circuit interlinks a magnetic path of the step-up transformer, thereby forming a primary winding of the transformer. A secondary winding from which head output is taken out is wound in the magnetic path of the transformer.
摘要:
An apparatus for cooling the cylinder head of an engine including a plurality of recesses formed in the cylinder head at the position located above the combustion chambers to accumulate oil therein and covers adapted to cover the recesses. Oil accumulated in the recesses serves to cool the cylinder head and the covers inhibit oil from being scattered from each of the recesses.
