摘要:
A process for preparing a biaxially oriented thermoplastic resin film which comprises: extending a thermoplastic resin sheet in a longitudinal and a transverse directions to form a film thereof, and heat treating the film under a temperature gradient descending from both edges to the center of the film along the transverse direction within a zone defined by the following formula (1) by employing a heater which is located over the film with an angle .theta. of the following formula (3) from said both edges to the center of the film to produce a thermoplastic resin film having uniform physical end chemical properties in the transverse direction:0.25.ltoreq.L.sub.1 /W.ltoreq.0.9 (1)tan.theta.=W/2L.sub.1 (3)wherein:L.sub.1 is the distance from the end point of the transverse extending to the end point of the heat treating; andW is the total width of the film.

摘要:
A process for preparing a thermoplastic resin film having uniform physical and chemical properties includes extending a thermoplastic resin sheet in a longitudinal direction so that the crystallization energy of the longitudinally extended sheet is 20 J/g or more to give a longitudinally extended sheet, extending the longitudinally extended sheet in a transverse direction to give a biaxially extended film, and heat treating the biaxially extended film to give the resin film.
摘要:
An image processing apparatus and control method are provided. The image preprocess apparatus includes an image receiver which receives an analog broadcasting signal; an image processor which converts the analog broadcasting signal into a digital broadcasting signal; and a filtering unit which selectively performs a low pass filtering on the analog broadcasting signal to filter a frequency higher than a preset frequency and transmits the selectively-filtered analog broadcasting signal to the image processor corresponding to a reception of the analog broadcasting signal by air.
摘要:
Chemically stable, insecticidally active pellets having a low moisture content and at least about 95% active ingredient are described, as well as a method for manufacturing them. The active ingredient is selected from a class of N-hydrocarboyl phosphoroamidothioate and phosphoroamidodithioate compounds as described in the specification. The pellets generally have a moisture content of about 0.5% by weight or less, preferably less than about 0.3% by weight. The pellets can be produced by one of two types of processes as described in detail, including a high pressure axial extrusion process and a low pressure basket extrusion process.

摘要:
A display window of a mobile phone, which prevents a deposited layer from being exposed and being oxidized/corroded, thereby improving not only the quality of the display window but also the reliability on the mobile phone provided with the display window. The display window has a deposited layer and a printed layer, which are formed in sequence on a transparent sheet, and a protective layer coated on outer edges of the deposited layer and printed layers, thereby preventing the deposited layer from being exposed.
摘要:
The present invention relates to cosmetic compositions and more particularly to skin-whitening cosmetic compositions comprising senkyunolide A as an active ingredient. The present invention discloses the novel inhibitory function of senkyunolide A isolated from Cnidium officinale and Ligusticum chuanxiong on the melanocyte-stimulating hormone (MSH), and provides MSH-inhibitory compositions and skin-whitening cosmetic compositions comprising the senkyunolide A. The compositions of the present invention show significantly enhanced skin-whitening effect owing to its efficient inhibition of MSH even in lower concentration.
