Title: Magnetic recording apparatus
Inventor: HIRANO SHINJI
IPC: G11B15/61
Filed: 1983-10-28
Granted: 1988-03-15
Abstract: The miniature tape cassette is loaded into the instrument in a position near to a guide drum and a group of tape guide elements. The guide drum encompasses rotating and stationary drums arranged concentrically, the rotaking drum having four video or magnetic heads aroun its circumference which rotate counterclockwise at 45 revs. per sec.  The magnetic tape(13) is wound around the gude drum (12) through an angle of 280 degrees and is guided to the drum from its cassette by guide rollers (23), guide pins (22), a tension pin and a drive shaft.  The positioning of the tape guide elements (22,23,28) is such that they form a tape track (34D) in which the tape is aligned vertically to a plane which runs at an inclined angle to a horizontal reference plane.

Title: A gas pour of cylinder
Inventor: PARK TAEK-HYON
IPC: F16F9/34
Filed: 1983-12-16
Granted: 1986-05-08
Abstract: A taper hole(4) is made in the middle of a cylinder cap(2). A few grooves are made along the jaw(5) of the taper hole and they work as gas passages. A steel ball(3) is set on the jaw. Its diameter is longer than that of the taper hole. As gas being injected, the steel ball is pushed into the taper hole by a injector(10). The friction between the ball and the taper hole prevents gas leakage. A projecting portion(9) is made by caulking hole's jaw(5) and it fixes the steel ball. This perfectly prevents gas leakage.

Title: Heat exchange structure
Inventor: BANA GORDEN R
IPC: F27D1/04
Filed: 1985-08-13
Granted: 1993-05-21
Abstract: A heat exchange structure is constructed from refractory blocks having three linearly aligned flue-forming openings extending from top to bottom of the block. The central opening is surrounded on four sides by refractory and the two end openings are surrounded on three sides. These refractory shapes are assembled in an open basketweave structure to form the heat exchanger. The resulting structure contains vertically extending, interconnected flues of two types, (1) flues of a first type interconnected at alternate layers in the structure to each of the four contiguously adjacent flues and (2) flues of a second type connected to opposed pairs of contiguously adjacent flues at alternate levels and to the other pair of contiguously adjacent flues at the intermediate levels. The net result is a stable heat exchange structure with relatively thin walls, relatively large flues, and means for creating turbulence in gas passing through the exchanger, thus increasing the rate of heat exchange.
