Title: Alloy excellent in corrosion resistance to molten zinc
Inventor: FUJINO SETSUO
IPC: C22C38/00
Filed: 1992-07-24
Abstract: PURPOSE:To obtain the economical alloy where strength is secured even if Ni content is reduced by forming a composition in which Mn is substituted for Ni in a 13Cr stainless steel. CONSTITUTION:This alloy has a composition consisting of, by weight, 0.15% or less C, 2.0% or less Si, 2.5-5.5% Mn, 10-15% Cr, 0.5% or less Ni, and the balance Fe. In this alloy, the content of Ni sharply reducing the corrosion resistance to molten zinc is reduced and the content of Mn is increased instead, thereby, deterioration in strength is prevented. Accordingly, corrosion resistance to molten zinc can be increased without deteriorating strength.

Title: Liquid-crystal display device
Inventor: TAKAHASHI TOMOAKI
IPC: G02F1/1368
Filed: 1986-08-25
Abstract: PURPOSE:To suppress a leakage current so as to obtain a high-contrast excellent display, by forming a highly insulating protective film on a picture-element electrode and setting the potential of a common electrode at a level at which a back gate channel can be cut off. CONSTITUTION:By covering a thin-film transistor and picture-element electrode 5 with a highly insulating protective film 6 the insulation between the electrode 5 and a common electrode 10 can be increased and, at the same time, by setting the potential of the electrode 10 at a level at which a back gate channel can be cut off, a leakage current is suppressed while liquid crystal 13 is driven by an alternative current. In other words, the potential of the common electrode 10 is previously set at a level which is sufficiently lower than the potential supplied to a source electrode 5a. When, for example, a voltage within the range of the source electrode 5a which is 0-+10V is to be supplied, the potential of the common electrode 10 is previously set at about -5--10V. Therefore, the liquid crystal 13 is driven by an alternative current and, at the same time, the leakage current caused by the back gate channel can be suppressed.

Filed: 1985-09-06
Abstract: PURPOSE:To obtain KOSAN (rhizome of Panax ginseng) having high quality and excellent preservability and useful as a crude drug, in a short time at a low cost, by heat-treating tissue culture product of medicinal ginseng at a high temperature and drying the product at a temperature lower than the heat- treatment temperature. CONSTITUTION:Callus produced by the tissue culture of medicinal ginseng (e.g. Panax ginseng, Panax japonicum, Panax quinquefolium, etc.) is proliferated by liquid cultivation or solid cultivation process. After removing excess water from the culture product if necessary, the produce is heat-treated at 70-110 deg.C for 0.5-6hr (preferably 1-3hr) and then dried with hot air at 40-60 deg.C for 6-24hr to obtain the objective KOSAN. EFFECT:Since the water exisiting in the cultured medicinal ginseng can be removed effectively in a short time, the growing of mold can be inhibited. The product has excellent preservability because of its hard and dense structure. The drying can be carried out without using particular apparatus such as freeze- drying apparatus.
