Abstract: A reversible heat-sensitive recording material comprising a resin matrix, an organic low molecular weight material, and a spherical filler, and a magnetic card obtained by forming a layer of the reversible heat-sensitive recording material on a magnetic recording member.

Abstract: A reversible heat-sensitive recording material, a method of recording and erasing information using the recording material, and a magnetic card using the recording material, the recording material comprising a reversible heat-sensitive recording material comprising a heat-sensitive layer containing a resin matrix and an organic low molecular weight material, said organic low molecular weight material containing at least one higher fatty acid having 16 or more carbon atoms and a sulfide represented by the formulaHOOC(CH.sub.2).sub.m --S--(CH.sub.2).sub.n COOH [I]wherein m and n each independently means an integer of 1 to 5, the ratio of the amount of said at least one higher fatty acid to that of said sulfide being from 90:10 to 10:90 by weight.

Abstract: A cylinder block for an engine is formed of a cylinder block body and a lower block which are cast from aluminum alloy and are fastened together to support therebetween a crankshaft of the engine. The upper half of a bearing portion for supporting the crankshaft is provided in the cylinder block body and the lower half of the bearing portion is formed by a bearing cap cast in the lower block.

Abstract: An engine cylinder block includes lower and upper cylinder block portions which are fastened together by bearing cap fastening bolts and cylinder block fastening bolts. The engine cylinder block is provided with a baffle plate, for separating a crankcase from an oil pan. The baffle plate is fastened to the engine cylinder block by the cylinder block fastening bolts. Bearing cap fastening bolts are arranged in a row parallel to an axis of rotation of the crankshaft at each side of a row of bearing caps. The cylinder block fastening bolts, each of which is located between adjoining bearing caps, are arranged in a row parallel to the axis of rotation of the crankshaft on each side of the row of bearing caps.

Abstract: A V-type engine cylinder block includes a mounting pedestal, integrally formed with the block in a V-shaped space between two cylinder banks and interconnecting the cylinder banks. A top wall is secured to the mounting pedestal and extends over almost the entire length of the V-shaped space in a lengthwise direction of the cylinder block. A plurality of bosses are formed with internal threads for securing a bracket, for mounting the cylinder block onto a car body, to one end wall of the cylinder block by bolts. The mounting pedestal and bosses are interconnected by ribs integrally formed with the cylinder block.

Abstract: A connecting structure for connecting a power unit of an automotive vehicle with the vehicle body, in which the power unit includes an engine and a transmission, and in which the engine has a cylinder block formed of an upper block and a lower block, in which a mount is located near the boundary of the engine and the transmission for supporting the power unit on the vehicle body so that each of the upper block and the lower block is mounted together as a unit with the transmission case by the mount.

Abstract: A method for making disposable absorbent articles which includes cutting a sheet into two elongated webs so that one edge of each web is straight and the other edge has alternating concave and convex portions, affixing the webs to a water-impervious backing sheet so that the straight edge portions thereof face each other and the alternating concave-convex portions face outwardly.

Abstract: A ring-shaped magnetic head includes magnetic cores made of a metallic magnetic material having a gap therebetween and being held between non-magnetic substrates. A metallic thin film is provided bridging the gap between the magnetic cores for establishing an electrical connection between the magnetic cores. The metallic thin film is formed on a surface of the magnetic head which is opposite to a surface for contacting a magnetic recording medium.

Abstract: A positive crankcase ventilation system for a V-type internal combustion engine has elongated first and second cylinder banks provided with first and second rows of cylinders offset, respectively, in a lengthwise direction to each other, thereby forming a dead corner on one end of each cylinder bank. A series of reinforcing bulk heads for reinforcing a series of main bearings holding a crankshaft divide a crankcase into a series of crankcase chambers. Each crankcase chamber is provided with a bottom opening and vent holes formed in the bulk head. An air introduction passage is provided by the side of and at the middle of each row of cylinders in the cylinder block for introducing filtered air into and through the crankcase and oil return passages are formed in each dead corner.

Abstract: A V-shaped cylinder block for a V-type engine includes a main oil gallery elongating in an axial direction of a crank shaft; a subordinate oil gallery elongating in the axial direction thereof; a linkage passage interconnecting the main oil gallery to the subordinate oil gallery; a first feed passage feeding oil from the subordinate oil gallery to a predetermined crank journaling portion disposed at least on one side of the cylinder block in the axial direction thereof without passing through the main oil gallery; a second feed passage feeding a lubricating oil from the main oil gallery to the crank journaling portions other than the predetermined crank journaling portion; and a pump chamber having a rotary shaft disposed in parallel to the crank shaft.
