IPC: G11B5/012
Filed: 1988-12-26
Abstract: PURPOSE:To raise the recording density by setting the azimuth angle so that the azimuth loss is fixed between any tracks with respect to a certain frequency.

Abstract: PURPOSE:To surely feed paper by reciprocating a sheet sucker holding means between a front edge upper position of a laminated sheet and its front edge rear upper surface while providing a blower means so as to be opposed facing to a front edge of the laminated sheet and blowing gas to the front edge of the sheet till the sucker holding means rises to the upper limit position of a stream of air from the upper surface of the sheet. CONSTITUTION:A sheet sucker holding means 31 can be moved reciprocating between the front edge upper position of a laminated sheet S and its front edge rear upper surface. The means 31, when it lowers, holds the sheet to be sucked being adapted to the rear upper surface of the sheet S excepting its front end part in a manner wherein the sheet S can be delivered to a sheet conveying means 8. While the means 31, when it rises, pulls up the sucked held sheet S toward the front in a conveying direction to be delivered to the sheet conveying means 8. Here providing a blower means 41 so as to be opposed facing to the front edge of the laminated sheet S, because gas is blown to the front edge of the sheet till the sucker holding means 31 rises to the upper limit position of a stream of air from the upper surface of the sheet S, the sheet can be separately fed sheet by sheet.

Title: Method for treating minerals
Inventor: KOYAMA TOMONORI
IPC: B01J19/00
Filed: 1988-12-26
Abstract: PURPOSE:To efficiently separate objects to be recovered which have been vaporized and minerals not to be recovered which are not vaporized by heating minerals to be treated in a combustion furnace to vaporize objects to be recovered, causing said objects to flow downward and further causing them to flow upward. CONSTITUTION:By burning fuels with oxygen or oxygen-enriched air, temperature within a combustion furnace 8 is raised up to a vaporizing or decomposing temperature or higher of objects to be recovered in minerals 1b to be treated. Particles of the minerals 1b are introduced into the combustion furnace 8 so that the objects to be recovered are vaporized and caused to flow downward together with combustion gas and then are caused to flow upward, whereby components 5 on the particles of the minerals 1b which have not been vaporized are caused to flow downward, while components 6 having been vaporized are caused to flow upward. As a result, separation of vaporized objects to be recovered from minerals not to be recovered which are not vaporized can be effected efficiently. Further, since a high-temperature combustion furnace can be employed in place of the conventional large-capacity power-consuming electric furnace, energy unit cost can be reduced.

Title: Condenser lens for infrared-ray type detector
Inventor: KIRIHATA SHINJI
IPC: G01V8/14
Filed: 1989-12-15
Abstract: PURPOSE:To obtain a compact, efficient condenser lens having a wide detecting area by crossing slantingly the rotation axis of respective hyperboloids of the 2nd face consisting of respective lenses of a multi-divided lens obtained by combining a 1st face shaped in plane and the 2nd face shaped in hyperboloid. CONSTITUTION:The condenser lens is a multi-divided lens obtained by combining the 1st face 10 shaped in plane and the 2nd face 20 shaped in hyperboloidal lenses, and the rotation axis C of the hyperboloids of the 2nd face 20 is crossing slantingly the plane constituting the 1st face 10 in respective lenses. Since an angle can be formed between parallel beams converged upon a focus without generating aberration and the normal H of the plane 10 in accordance with the angle formed between the rotation axis C shared by respective hyperboloidals of the Fresnel's face constituting the 2nd face and the plane 10, infrared rays can be efficiently converged from a required direction without directing the lens to the necessary direction. Thus, the compact infrared-ray type condenser lens for a detector having high converging efficiency and a wide detecting area can be obtained.

Filed: 1988-12-23
Abstract: PURPOSE:To simplify installation of pins and prevent breakage of pins and a circuit board by inserting a terminal pin previously in a terminal pin insert hole, forming an insulated circuit board in the condition that this transcription plate is put in a die for molding, and connecting electrically a conductive circuit pattern with the terminal pin. CONSTITUTION:First a terminal pin 30 is inserted in a pin insert hole 41 provided in a transcription plate 40 and fixed provisionally. Then this transcription plate 40 is fitted in a molding die 50 for insulated circuit board. If a molding is taken out of the die 50 after completion of this molding process, insulated circuit board 10 is accomplished, whereon a conductive circuit pattern 20 has been transcribed, and therein also terminal pins 30 are embedded. Then these terminal pins 30 are connected electrically with the circuit pattern 20. This allows omission of such a troublesome process that pin insert holes are bored in the circuit board one by one for pressure fitting of terminal pins, and also it is free from risk of breakage of the terminal pins and/or circuit board due to poorly performed pressure fitting of terminal pins.
