Granted: 2004-05-10
Abstract: A power pack is mounted on the side wall of a refrigerant tank in which the internal pressure is reduced and a refrigerant is held in such a way that a heat transfer panel on which a power element is mounted can contact the refrigerant. The refrigerant boiled and gasified by heat from the contact part of the heat transfer panel 19 is guided into a radiation part planted on the top of the refrigerant tank 11. The radiation part is composed of a plurality of hollow tubular bodies having flat cross sections. The plurality of radiation tubes are laid out in parallel with each other at specified intervals, the upper ends thereof being closed and the lower ends thereof being open to the inside of the refrigerant tank so that the gasified refrigerant is guided thereinto. Here, the natural convection of the air is generated in the up/downward directions by the plurality of the radiation tubes, and the effective heat radiation is achieved thereby.

Abstract: The rewinding machine of the present invention produces rolls or logs of paper such as toilet paper, kitchen towels, etc. It includes an upper winding cylinder (9; 109), a lower winding cylinder (10) forming with the upper one an interspace (12), a mobile roller (14) able to define with said two cylinders a space in which the roll is wound. A pusher (22) inserts individual cores (A) in said interspace, and an applicator (34, 36, 38) wets the cores with adhesive. In combination with one (9; 109) of the two winding cylinders (9, 109; 10) a fixed surface (52; 80) is provided. A web of incoming paper N slides along the surface (52; 80). The pusher (22) moves the core (A1) at an insertion speed which is lower than the paper-feeding speed. During its insertion into the interspace (12) the core (A1) moves toward the fixed surface (52; 80), providing a temporary braking effect on the web N lying between the fixed surface (52; 80) and the core (A1). This causes the web to tear between the just-completely formed roll (R) and the incoming core (A1).

Abstract: PURPOSE:To select mesa type semiconductor pellets without mistaking the forms of their surface electrodes for the forms of their rear electrodes to shake them in a pallet by a method wherein first and second opening parts, whose forms are different from each other, for pellet shaking-in use are respectively provided in a pallet main body for the pellets and the pellet main body is made to vibrate in a state that it is slanted. CONSTITUTION:A method of shaking pellets 7 in a pallet is performed by a method wherein after a pallet main body 1 is placed on a vibrating table, vibrations are applied and moreover, the table is slanted. Whereby a multitude of the pellets 7 are made to slidingly descend on the main body 1 and are respectively shaken in designated positions. At this time, each pellet 7 housed in an opening part 3 in a state that a cathode 5a is faced downward is made to protrude by the vibrations and is housed in the opening part 3 in a state that the cathode 5a is faced upward. A state that the two pellets 7 are housed in the opening part is unstable and either of the two pellets 7 is made to protrude. Thereby, the pellets are reliably selected without mistaking the forms of their surface electrodes for the forms of their rear electrodes and can be shaken in the pallet.

Abstract: PROBLEM TO BE SOLVED: To improve a signal transmission speed and reduce electrical noise, by fixing an inner lead portion to a circuit forming surface by an insulating adhesive partially formed at a portion where a circuit forming surface faces the inner lead portion, thereby reducing stray capacity between the semiconductor chip and the lead. SOLUTION: An interval between a semiconductor chip 1 and a portion at the outer lead side from a portion adhered to an insulating film 4 of an inner lead 3A formed to a lead frame is made wider than the interval between the semiconductor chip 1 and a portion joined to the insulating film 4 by means of a stepped structure. Also, the bonding between the main surface of the semiconductor chip 1 and the insulating film 4 and the bonding between the insulating film 4 and the inner lead 3A is performed through an adhesive 7. By doing this, the stray capacitance between the semiconductor chip and lead can be reduced smaller and the signal transmission speed can be improved and electrical noise can be reduced.

Abstract: A simple and precise method of controlling the gap position (obliqueness and height) of magnetic recording installations with n tracks (n=1, 2 . . . ) is obtained by subdividing at least one track of a recording tape into two auxiliary tracks in accordance with the given recording format, which auxiliary tracks are recorded at the center to center track distance of d, using a special head with correct gap position. The recording wave length and magnetization are preferably equal due to the width of the auxiliary tracks being equal. The auxiliary track 1 is recorded continuously while the auxilary track 2 is recorded at time intervals with a signal of equal magnitude but with different phase angles. Each time interval has a phase angle associated with it. The magnitude of correction of the gap required can easily be determined from a graph showing the voltage level difference measured at two different phase positions. The oblique angle of the gap may be measured and corrected by these means and in one variation of the invention the height adjustment of the head can also be measured and corrected.

The paste is continuously discharged from the nozzle while the paste line is being drawn. The paste line is drawn while moving any of the paste-applied body, the nozzle and the paste. The paste-applied body is a lead frame, and the paste is an adhesive for die bonding. The drawing pattern is a figure made up of a plurality of segment lines, preferably a figure in the radial form. The drawing pattern is a figure including an enclosed shape. At least one segment line is formed of two drawn lines by moving any of the paste-applied body, the nozzle and the paste to go and return. The drawing pattern is formed such that the total number of start and end points of drawn lines is not larger than the number of segment lines, and that the start and end points of drawn lines are positioned other than the ends of the drawing pattern. The drawing pattern is formed with a minimum number of points at which the drawn lines are returned in a drawing process. <IMAGE>

Abstract: Very potent, stable, odorless, and phenol-free virucidal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses. Because of the low concentration of active ingredients, these solutions exhibit a very low toxicity, making them suitable for topical applications as antiseptics.
