Abstract: A thin film magnetic head for perpendicularly recording and reproducing is disclosed. The magnetic head comprises a main magnetic pole of a thin film, a spiral coil of an electrically conductive film disposed on one side of the main magnetic pole, a first auxiliary magnetic pole of a thin film covering the coil, and a second auxiliary magnetic pole disposed on the other side of the main magnetic pole, forming a substrate or being formed on a non-magnetic substrate. The distributed magnetic leakage path between the main magnetic pole and the second auxiliary magnetic pole plays an important role in the present invention. When the second auxiliary magnetic pole is properly arranged, the magnetic flux flowing through two magnetic paths and interlinking the coil, are cancelled by each other and edge noise due to magnetic flux generated at the second auxiliarly magnetic pole by a magnetic transition of the recording medium is minimized.

Abstract: The disclosure is concerned with arrangements which are disposed on a preparative route leading to water analysis from extraction of water samples. Specifically, an injection unit for injecting water samples into a combustion chamber is improved, wherein a slide block type is employed, but conventional trouble of accumulation of involatile matters around injection site is avoided by change of designs with a slide block and an injection pipe. Next, a micro syringe unit for extraction, measurement of water samples is improved by arranging two syringes connected in branch, wherein a second syringe is intended to feed a quantity of water to dilute a target sample water which will be extracted to a first syringe and in operation, the second dilution water will be influenced to the target first water on route leading to the first syringe. Third, a calibration unit is introduced to mix a reference water sample which has been known of its volume and its concentration into a target water sample to be analyzed.

Abstract: A socket and plug coupling assembly wherein the socket is a box-like frame with walls of the top and front partially removed, and has pins arranged on a bottom to extend upwardly. At the base of the pins the remaining front stub wall forms a brace in which a slope is formed to be inclined inwardly downwardly of the socket frame. The plug is shaped to be a box-like frame with openings on a bottom continuing to a front wall and the plug has contact members inside the frame openings facing frontwardly. A nail is provided at a rear end of the plug frame extending downwardly from the bottom. In a coupling action of the plug with the socket, first, the nail of the plug is obliquely contacted on the slope of the socket via a face to face approach of the plug toward the socket and then, rotating inwardly about the contact of the nail with the slope, the plug is turned to couple with the socket.

Abstract: An independent wheel suspension system includes a pair of upper lateral link members and a pair of lateral link members for supporting a wheel carrier to the vehicle body. By providing a difference in elevation between the outer ends of the link members for the upper and/or the lower pair of lateral link members, an anti-dive property can be obtained. Further, by providing an appropriate inclination to the rear lower lateral link member, the tendency to form a toggle between the knuckle arm of the wheel carrier and the tie rod is reduced. Also, by making the front lateral link member more upwardly inclined than the rear lateral link member for each of the pairs, an anti-dive effect can be produced without changing the caster angle and other property of the suspension system during cornering maneuvers.
