Abstract:
A disclosed cleaning device for removing adhering matter from a surface of a member subject to cleaning includes a belt-shaped film member arranged in a stretched configuration capable of being wound or endlessly move in a direction opposite to a surface movement direction of the member subject to cleaning while being in contact with the surface of the member subject to cleaning, and a cleaning blade configured to abut on the surface of the member subject to cleaning via the belt-shaped film member at a position where the belt-shaped film member is brought into contact with the member subject to cleaning.
Abstract:
A section of predetermined geometry and area is provided on or in a die pad of a lead frame and taken as a mark to be used for checking the position of a semiconductor chip. If the semiconductor chip is placed outside an allowable range in the X direction, the semiconductor chip overlaps the mark, thereby changing the geometry of an observable portion (slanted portion) of the mark. By means of the change, a positional deviation of the semiconductor chip in the X direction can be ascertained. A positional deviation of the semiconductor chip in Y direction is determined, by observing whether or not an electrode is situated between extensions of sides of a certain portion of the section.
Abstract:
In a semiconductor device fabricating method, a plurality of wafers each having a plurality of chips into is carried and is placed in a die bonder. Chips taken out from the plurality of wafers is bonded together, respectively, and superpose in a stack by bonding layers to form a chip assembly. The chip assembly to a die pad by a bonding layer is bonded. Thus, the die bonder is able to bond the chip assembly consisting of the plurality of chips to the die pad, so that the process time of a die bonding process for bonding the plurality of chips to the die pad is comparatively short, the semiconductor fabricating apparatus produces semiconductor devices at an improved productivity, has a comparatively small scale and needs a comparatively low equipment investment.
Abstract:
A method of making a semiconductor device having a lead-on-chip structure includes bending a die pad extending from an outer frame outwardly from the outer frame. Thereafter, with the die pad in a convenient position, a semiconductor chip is die-bonded to the die pad. Thereafter, the die pad is bent back toward the outer frame so that it is generally parallel to but spaced from the outer frame with leads extending from the outer frame being generally parallel to the semiconductor chip. Electrodes of the semiconductor chip are connected by wire-bonding to the leads extending from the outer frame. After resin molding, the outer frame lying outside the resin package is severed and removed, completing the lead-on-chip semiconductor device.
Abstract:
Disclosed is an infusion preparation for nutrient supply use. It comprises a sugar, amino acids, electrolytes and a fat emulsion. It has an excellent shelf life without causing precipitation, denaturation and the like in spite of the simultaneous presence of these components. Also disclosed is a container filled with infusion liquids comprising a first and a second compartments separated from each other by a separation means, wherein an infusion liquid containing a fat emulsion and a sugar is included in the first compartment and another infusion liquid containing amino acids and electrolytes is included in the second compartment. Further disclosed are an infusion preparation comprising a fat emulsion and a sugar, and an infusion preparation comprising amino acids and electrolytes. An infusion preparation containing a sugar, amino acids, electrolytes and a fat emulsion can be obtained easily and aseptically upon use, by simply removing a separation means attached to the container and mixing the two infusion liquids.

Abstract:
A solder material comprises a first solder plate and a second solder plate having a thickness equal to or larger than 1 micron provided at the both surfaces of the first solder plate comprising material-having a lower melting point than the first solder or material which reacts with the first solder to produce an alloy having a lower melting point than the first solder.A junctioning method comprise putting the above-described solder material inserted between two objects to be junctioned to each other; heating the solder material to a temperature higher than the melting point of the second solder or the alloy and lower than the melting point of said first solder thereby to melt the second solder or the alloy; and thereafter cooling or keeping the solder material at a temperature in the vicinity of the melting point thereby to junction the objects to be junctioned to each other. The second solder plate has preferably a thickness less than 5 microns and the first solder plate has preferably a thickness equal to or larger than 30 microns. By this construction, the interval between the objects to be junctioned can be controlled to a predetermined thickness and the stress functioning to the objects can be relaxed as well as there arises no positional deviation between the objects.
Abstract:
An image reading and recording apparatus comprises a reader for reading an image of a document by scanning a document and a recorder for effecting recording of the image read by the reader on a recording medium by scanning one side of the recording medium. A driving and controlling device drives and controls the reader and the recorder in such a manner that the image recorded on one side of the recording medium by means of the recorder will be inverted with respect to the image of the document.
Abstract:
An original reading apparatus which prevents lamp blackening includes a lamp for illuminating the original, and reading circuitry for reading an image formed on the illuminated original. Control circuitry is provided to apply to the lamp a first predetermined voltage after reading the image formed on the original has been completed, if a voltage applied to the lamp at the time of original image reading is lower than a second predetermined voltage. The first predetermined voltage is higher than the voltage applied to the lamp at the time of the original image reading.
Abstract:
During original document scanning, the forward clutch effects scanning travel of the optics unit in a copying machine having user selectable modes for magnification copying and is normally disengaged by detection of the trailing edge of a transfer sheet being transported through the machine; the return clutch for reverse optics unit travel is simultaneously actuated by detection of the sheet's trailing edge to return the optics unit to its original position. In the event that the trailing edge is not detected before expiration of a predetermined time period corresponding to maximum permissable forward travel of the optics unit for the selected magnification mode, the forward clutch is immediately disengaged, although the return clutch is not engaged until the sheet's trailing edge is subsequently detected.
