Abstract: Moving contact pieces formed by plate spring members are fixed in the case with terminals, and first and second contacts are mounted on the other free ends of the moving contact pieces. A metal cover is mounted around the case, and a rectangular-shaped bimetal is fixed at one end to the cover so that a slider is interposed between the other free end of the bimetal and the second contact. The first and second contacts are held in contact with each other while ambient temperature is normal. An arcuate spring has one end positioned at a point S in the interior of the case and has the other end engaged at a point P with the extremity of the moving contact piece. As temperature excessively rises, the contacts are pushed by the free end of the bimetal through the slider, by which the arcuate spring causes the moving contact piece to perform a snap action to separate the first contact from the second contact.

Abstract: A heat-sensitive plate is substantially rectangular, has its one end portion fixed to a second terminal plate and has a movable contact mounted on the other end portion. The one side of the heat-sensitive plate facing a fixed contact forms a high expansion coefficient side and the other side a low expansion coefficient side. The heat-sensitive plate has a protrusion protrusively provided on the low expansion coefficient side centrally thereof by press working with a small outer diameter and a large curvature, and an annular press-thinned portion formed by press working concentrically with the protrusion and having an inner diameter appreciably larger than the outer diameter of the protrusion. In the initial state the heat-sensitive plate is held curved in a funnel shape protrusive about the protrusion on the low expansion coefficient side.

Abstract: In a circuit-protector-built-in power plug, the plug body has in its front a curved concavity, in which plug terminals are planted, a circuit protector which interrupts the circuit when supplied with excess current, and a reset knob for resetting the circuit to its closed state through manipulation from the outside the plug body. The reset knob is so disposed in the concavity that it does not protrude beyond the surface of the plug body. A slidable lid covering the concavity prevents access to the reset knob when the plug terminals are inserted into receptacles.

Abstract: A magnetic recording medium excellent in fungiresistance and having high safety, lubrication and durability is provided, with the magnetic properties not being affected. An anti-fungus agent is added to the recording medium. The added anti-fungus agent is a compound (I) in an amount of 0.005 to 5.0% by weight of the magnetic coating layer: ##STR1## where R stands for C.sub.1 to C.sub.6 straight or branched alkyl, cyclohexyl or, ##STR2## n is an integer of 1 or 2, and X stands for H, CH.sub.3, Cl, Br or I.

Abstract: An optical recording medium, particularly a magneto-optical recording medium, resistant to oxidation deterioration even in a hot and humid atmosphere, is provided by forming an organic protecting adhesive layer of a UV-curved resin having (1) an acid value of not more than 1.5; and (2) a softening point of not less than 50.degree. C. The UV-curved resin layer comprises 15 to 85% by weight of acrylate and/or methacrylate having at least three functionalities; 15 to 70% by weight of a compound having a linear structure and having a molecular weight of at least 300, the compound preferably having at least one ethylenically unsaturated bond and a molecular weight of at least 150 per ethylenically unsaturated bond; and (3) a photopolymerization initiator.

Abstract: A static hydraulic pressure type continuously variable transmission formed with a hydraulic closed circuit between a swashplate type hydraulic pump and a swashplate type hydraulic motor, the hydraulic motor being constructed such that its motor cylinder is integrally connected to an output shaft which extends through a motor swashplate and a swashplate holder for supporting the back surface of the motor swashplate, a swashplate anchor for supporting the back surface of the swashplate holder being axially immovably connected to the output shaft through a thrust bearing, and that the swashplate anchor is unrotatably connected to a casing which rotatably supports the output shaft. The motor cylinder and a pump cylinder of the hydraulic pump are provided coaxially with the hydraulic closed circuit interposed therebetween.

Abstract: An ultrathin film composed substantially of silicon-containing polyurea comprising polyaddition bonded units derived from(A) at least one polyamine selected from the group consisting of silicon-containing polyamines and hydrocarbon-type polyamines, each of said polyamines containing at least two primary or secondary amino groups in the molecule, and(B) at least one polyisocyanate compound selected from the group consisting of silicon-containing polyisocyanates and hydrocarbon-type polyisocyanates, each of said polyisocyanates having at least two isocyanate groups in the molecular chains;provided that when the polyisocyanate compound is the hydrocarbon-type polyisocyanate alone, at least one of the selected polyamines is a silicon-containing polyamine containing at least one terminal amino group in the molecule.

Abstract: An intake manifold and an exhaust manifold, both for use with an internal combustion engine, are provided with a common wall for transmission of heat from the hot exhaust gases to the air-fuel mixture in the intake manifold. A movable baffle is provided for varying the amount of heat transfered to the air-fuel mixture, and the operation of this baffle is controlled by a first device responsive to ambient temperature outside said manifolds, and also by a second device responsive to the intensity of intake vacuum pressure. The baffle may be mounted in either manifold and may be mounted to swing or slide with respect to the stationary heat transmitting wall which separates the manifolds.
