Abstract: A die bonding apparatus includes a first member having a surface to be die bonded on which solder is disposed, a base portion for mounting the first member thereon in a predetermined position, a second member disposed in an inclined manner with respect to the first member and faces the solder, and an inclination attenuating member for inclining and holding the second member with respect to the first member to attenuate an angle of inclination &thgr;1 of the second member with respect to the first member in a state where the solder is melted. In a state where the first, second members, and the solder are heated and the solder is melted, die bonding is effected while the inclination attenuating member gradually attenuates the angle of inclination &thgr; 1, so that it is possible to suppress the occurrence of bubbles in the solder.

Abstract: Disclosed herein is a magnetic tape unit having a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is traveled in contact with the magnetic head during a read/write operation of the magnetic head. During a rest period where the read/write operation of the magnetic head is not performed, a reciprocating motion of the magnetic tape by a small distance is performed with a predetermined period. A temperature in the vicinity of the magnetic head is detected by a temperature sensor. The predetermined period is changed according to the temperature detected by the temperature sensor. Accordingly, the adhesion of the magnetic tape to the magnetic head can be well prevented irrespective of the temperature inside the tape unit.

Abstract: A positive resist composition contains (A) a novolak resin having a weight average molecular weight calculated as polystyrene of 2,000-20,000 wherein 2.5-27 mol % of the hydrogen atom of a hydroxyl group is replaced by a 1,2-naphthoquinonediazidosulfonyl group and (B) a low molecular aromatic compound having phenolic hydroxyl groups and 2-20 benzene rings wherein the ratio of the number of phenolic hydroxyl groups to the number of benzene rings is between 0.5 and 2.5. By forming a resist layer on a substrate from the positive resist composition and baking the resist layer at 90-130° C., followed by exposure and development, there is formed a resist pattern having an undercut of desired configuration. Owing to high resolution and improved dimensional control, heat resistance and film retention, the resist pattern lends itself to a lift-off technique.

Abstract: A magnetic tape unit with a magnetic head for reading and writing data from and onto a magnetic tape. The magnetic tape is kept in constant contact with the magnetic head, and a reel motor travels the magnetic tape kept in contact with the magnetic head. Adhesion of the magnetic tape to the magnetic head is prevented by slowly driving the reel motor to travel the magnetic tape at a speed lower than a normal traveling speed for a read/write operation of the magnetic head, during a rest period when the read/write operation of the magnetic head is not performed.

The work-carrying assembly is composed of a main carrier frame suspended from the overhead track assembly, an auxiliary carrier frame supported by the main carrier frame and arranged to be tiltable with respect to the main carrier frame in a fore-and-aft direction of the work-carrying assembly, and a hanger frame supported by the auxiliary carrier frame and angularly movable with respect to the auxiliary carrier frame about an axis normal to a plane perpendicular to the fore-and-aft direction of the work-carrying assembly. The auxiliary carrier frame is caused to tilt with respect to the main carrier frame in a fore-and-aft direction of the work-carrying assembly by the aid of a first set of guide rollers and rails.

Abstract: Two parallel guide rails are arranged to put therebetween a stationary die of the hot-press machine and a table for sliding therealong respective movers by which a facing layer is carried from a first position to cover the table to a second position to cover the stationary die. First clamping means is disposed on the movers to clamp longitudinally opposed ends of the facing layer, and second clamping means is connected to the stationary die to clamp laterally opposed ends of the facing layer when the facing layer which has been kept clamped by the first clamping means is brought to the second position by means of the movers.

Abstract: A trim panel, which is composed of a substrate of corrugated paperboard and a decorative and/or protective skin layer, is produced by press-forming the substrate into a desired shape by a hot-press, parting the movable die of the press from the stationary die to leave the shaped substrate in the latter die, dragging a sheet material employed as the skin into the press so as to stretch above the shaped substrate, and pressing the stretched skin material against the shaped substrate, interposing an adhesive layer therebetween unless the skin material has an adhesive property, with application of heat to accomplish adhesion. The hot-press is combined with a substrate feed mechanism and a skin material feed mechanism which includes a piston rod with a sheet-grasping device mounted thereon and can serve also the function of withdrawing the shaped and laminated product from the stationary die.

Abstract: In a method of press-forming a planer board of corrugated paperboard into a curved board which serves as the substrate of, for example, an automobile roof trim board by utilizing a thermoplastic adhesive in the production of the corrugated paperboard and applying heat to the planer board through dies in a hot-press, the liners of the corrugated paperboard are prevented from wrinkling by preheating the planer board so as to soften the thermoplastic adhesive therein immediately before placement between the dies. An apparatus to perform this method comprises a board carrier which has heaters and can carry the planer board into the hot-press with continued heating of the board.

Abstract: One of two liners between which a corrugated medium is disposed is temporarily or expediently fixed to the medium. Upon press-forming, slippage of the temporarily fixed liner relative to the medium occurs, so that no wrinkles are produced in the liner.

Abstract: In the production of a wall covering board which is shaped and composed of a substrate of corrugated paperboard and a decorative and/or protective skin layer, a hot-press for bonding of the skin to the substrate either simultaneously with or subsequently to shaping of the substrate is combined with a skin material support mechanism and a drag mechanism including a sheet-grasping device mounted on the piston rod of a piston actuator. The support mechanism supports, with friction force, a belt of a sheet material employed as the skin at its one end horizontally on one side of the press. The piston rod is horizontally extended from the opposite side of the press to traverse the press and allow the grasping device to grasp the supported end of the belt and then retreated until the grasping device returns to the opposite side of the press, so that the belt is stretched between the stationary and movable dies of the press. By applying heat and pressure to the stretched belt through the movable die, the belt, i.e.

Abstract: Apparatus for inelastically deforming an initially flat blank of a corrugated fiberboard, comprising two die blocks movable relative to each other and having complementarily convex and concave pressing surfaces and blank retaining means adapted to clamp opposite marginal portions of a blank of a corrugated fiberboard being warped between the die blocks with the marginal portions urged sidewise inboardly of the die blocks, the blank retaining means being operative to restrain the blank from being moved in a direction parallel with the marginal portions but to allow the marginal portion of the blank to move the marginal portions of the blank sidewise inboardly of the die blocks in a direction perpendicular to the marginal portions so that not only production of creases in curved portions of the blank but production of fissures as would be caused if the blank is excessively stretched between the opposite marginal portions of the blank are precluded.

Abstract: A method of producing a shaped wall covering material composed of a corrugated cardboard substrate, a porous buffer layer adhered onto one side of the substrate and a thermoplastic resin liner coated on the outer surface of the buffer layer. The starting materials are set in a hot-press in an orderly piled arrangement with interposed adhesive materials and subjected to press-shaping between male and female dies with application of heat. During the shaping operation, air is sucked from the gap between the substrate and the shaped surface of one die through holes intentionally formed in this die. The resultant attraction of the piled materials to this die facilitates the shaping and prevents a layer-separation or deformation of the product attributable to a sticking tendency of the liner to the other die.

Abstract: In the production of a trim board such as an automobile roof trim board using a corrugated paperboard substrate which is bulged or dented in a comparatively small area and has an aperture in this area for the installation of a separate article, at least one linear notch is formed in a flat board of corrugated paperboard so as to extend transversal to the ridges of the corrugated medium and be entirely included in the area of the aperture as a preparatory procedure to press-forming of the corrugated paperboard. The presence of the notch allows some deformation of a tensioned liner also in the same direction as the ridges and hence precludes the appearance of cracks in the bulged or dented area. The notched region of the shaped board is thoroughly cut away as the result of the formation of the intended aperture.
