Title: Soybean milk-containing alcoholic drink
Inventor: SUGIMOTO NAOTSUGU
IPC: C12G3/04
Filed: 1984-08-09
Abstract: PURPOSE:The titled drink containing vegetable protein, showing a refreshing flavor, causing no precipitate, comprising fermented soybean milk and/or acidic soybean milk, a drinkable alcohol, high methoxyl pectin, and, if necessary, a carbonic acid gas. CONSTITUTION:The titled drink comprising 1-15% (wt/vol) fermented soybean milk and/or acidic soybean milk, 3-16% (wt/vol) calculated as alcohol content of a drinkable alcohol, 0.08-1.00% (wt/vol) of high methoxyl pectin, and, if necessary, a carbonic acid gas.

Title: Formation of contact hole in thin film transistor
Inventor: UEDA TORU
IPC: H01L21/306
Filed: 1991-07-05
Abstract: PURPOSE:To provide a method of formation of a contact hole in a thin film transistor capable of forming therein a small diameter fine contact hole. CONSTITUTION:Wet etching is carried out for a contact hole formation scheduled part to form a contact hole 8 up to the upper part of the same, and the upper edge of the contact hole upper part is tapered. Anisotropic dry etching carried out thereafter is interrupted on the my to an insulating film 7, and a remaining insulating film 7 part underlying the etched insulating film 7 is etched in a wet manner. For this, the etching at the time when etching reaches a source region 5 and a drain region 6, is carried out in wet etching with satisfactory greater selection ratio instead of anisotropic etching, and hence no overetching is carried out. Further, since transversal spreading is mainly carried out upon the wet etching, but the depth of the contact hole 8 formed by the wet etching is shallow, the transversal spreading is limited.

Then it is checked whether the stable working of an MP is possible or not. At the same time, a power supply voltage detecting circuit 5 detects the range of the power supply voltage E and checks whether the stable working is possible or not. When the second outputs of both circuits 4 and 5 are equal to '1', a stable working confirmation circuit 6 set at the next stage produces '1' to a reset signal output circuit 7, etc. Thus the reset signals C are surely outputted to the peripheral devices and a RAM/ROM 21 for display of the stable working of the MP.
