Title: Production of polypropylene composition film
Inventor: TABUSE HIROSHI
IPC: C08J7/00
Filed: 1979-04-13
Abstract: PURPOSE:To produce a polypropylene composite film one surface of which has excellent heat sealability and the other surface of which has excellent affinity for printing inks, etc., by treating a propylene film having a lamination of a low-melting resin on one surface, with corona discharge in a nitrogen atmosphere having an oxygen content equal to or lower than a specific level. CONSTITUTION:A composite film prepared by laminating one surface of a polypropylene film with a low-melting resin is subjected to corona discharge treatment, while at least one surface of the composite film is kept in a nitrogen atmosphere having as oxygen content of below 5vol%. A particularly preferred example of said low-melting resin is an ethylene/propylene random copolymer having an ethylene content of 1-7wt%. In conducting the corona discharge treatment of the composite film, a manner in which both surfaces of the film are kept in a nitrogen atmosphere having an oxygen content of below 5vol% is preferred, because almost no lowering in the heat sealability occurs under such conditions.

Title: Plastic bottle with variable capacity
Inventor: SUMINO TOSHIHARU
IPC: B65D21/08
Filed: 1994-02-03
Abstract: PURPOSE:To vary a capacity of a bottle and fix the capacity by providing stretchable folds on a body. CONSTITUTION:Stretchable folds 1 are provided on a body of a plastic bottle to vary its capacity. If the bottle is easy to bend with lateral force so that fixing the bottle capacity is insufficient, a film may be wound or an adhesive seal may be adhered. Thus when a liquid amount is reduced, the bottle capacity is reduced to exhaust air inside the bottle so that oxidation of contents is prevented or carbonic acid may not likely to go out from a carbonated drink. Further, since a bottle volume is reduced in recycling, a cost for treating and transporting is reduced to facilitate recycling of the bottle.

IPC: H01S5/10
Filed: 1990-02-26
Abstract: PURPOSE:To detect the strength of light while absorbing little light even if a signal light is received serially by the plural number of recipients by causing the electron level of a subband of the quantum well structure(QWS) or quantum line structure(QLS), which was divided into the plural number of parts by a photo Stark effect caused by subband-to-subband virtual transition, to shift. CONSTITUTION:Light having the photon energy which is close to a subband spacing of electrons in upper and lower paths 2, 3 is applied to the central part. At this time, the subband structure and the photo energy are set so that they may have the specified relation with each other for avoiding absorption of light. Since the electron level of the subband of the upper and lower paths 2, 3 shifts by the so-called photo Stark effect, the wavenumber of electrons, which are injected from a source electrode 5 and move toward right in the paths 1, 2, 3, differs in the upper and lower paths 2, 3. By making the amount the electron level of the subband shifts in the upper path 2 different from that in the lower path 3, a variation in the wavenumber of electron waves in the upper path 2 differs from that in the lower path 3.

Abstract: PURPOSE:To correctly observe an image of a scanning tunnel microscope(STM) by adding a displacement amount of a cantilever to a signal of the microscope to correct it. CONSTITUTION:When an image signal B (STM image) is obtained by applying a bias voltage to a sample 2 and so feeding back it to a Z-PZT that a tunnel current detected by a conductive cantilever 4 becomes constant, a distance between the lever 4 and the sample 2 is varied under such a control that the current becomes constant at positions of a sample surface where the current easily flows and the current scarcely flows. Then, a displacement amount of the cantilever 4 measured by a displacement detector 5 is added to a height signal from the Z-PZT by an adder 6, the height is collected to a height when the cantilever 4 is not displaced, and the STM image is observed with it as the signal B. As a result, the STM image of a mode in which a true tunnel current is constant without depending upon ease of flowing of the current is obtained.
