Abstract: PURPOSE:To highly integrate a device by a method wherein a vertical groove is formed in a silicon substrate and two or more MOS transistors are formed in one groove while a side wall part of the groove is used as a gate. CONSTITUTION:An n-type impurity region 3 is formed in a p-type silicon substrate 1 by a dry etching operation using an oxide mask 2. Then, an oxide film 4 is filled into a groove by using an LP-CVD method; a gate electrode ot a MOS transistor is separated by the oxide film 4; after that, an n-type impurity region 5 to be used to form a source and a drain ot the MOS transistor is formed by an As ion implantation method. In addition, an oxide film 7 is formed; a phosphorus-doped polysilicon electrode 8 is formed by the LP-CVD method for the gate electrode of the MOS transistor. The polysilicon electrode 8 on the buried oxide film 4 is shaved by using an etching-back method until it disappears; two MOS transistors can be formed inside the groove. By this setup, a device can be highly integrated.

Title: Method of preventing staining of sealant
Inventor: TAKAGI NORIHIDE
IPC: C09D175/04
Filed: 1988-02-05
Abstract: PURPOSE:To prepare a sealant which is nonstainable and has improved weather resistance, by applying a polyisocyanate urethane prepolymer soln. to the surface of a sealant in an uncured state. CONSTITUTION:A polyisocyanate urethane prepolymer soln. (e.g., a soln. of a polyurethane prepolymer having at least two aliph., araliph. or alicyclic molecule-terminated isocyanate groups in an org. solvent) is applied to the surface of a sealant (e.g., polyurethane or modified silicone sealant) in an uncured state by spraying, brushing or the like. The aforesaid method of preventing staining makes the rate of curing of the surface of the sealant higher than that in the case of untreatment, which remarkably shortens the after-tack period. This makes it possible to prepare a sealant having nonstainability and improved weather resistance.

Next, the sintered mixture is crushed in a mortar before the crushed mixture is sieved so as to obtain a positive active material which can pass through a sieve of 400 mesh. After the thus obtained positive active material is mixed with graphite powder used as a conductive agent and fluorine resin powder used as a binder in a ratio of 80:15:5 (by weight), the mixture is molded before being thermally treated at 300 deg.C for one hour, thereby making a positive electrode. A negative electrode is made by punching a rolled lithium plate into a given dimension. Electrolyte is prepared by dissolving lithium perchlorate in a mixture solvent composed of equal volumes of propylene carbonate and 1,2-dimethoxyethane. A separator consisting of a nonwoven polypropylene fabric is mpregnated with the above electrolyte.

Abstract: PROBLEM TO BE SOLVED: To keep white balance at the time of picking up images by setting emitted light spectrum characteristics in the visible light area of the film illumination light of a light source so as to be relatively large on a short wavelength side and small on a long wavelength side compared to a white light source. SOLUTION: In order to cope with the white balance largely unbalanced at the time of picking up the images recorded on a negative film 2, a fluorescent lamp light source 4 coping with a negative whose light emission characteristics are different from a normal white fluorescent lamp, which is provided with the light emission spectrum characteristics for compensating color absorption in the base layer of the negative film 2 is used. That is, the light emission spectrum characteristics of the fluorescent lamp 4 are designed by considering the color absorption in the base layer of the negative film 2 so as to enlarge the intensity of a blue light component B and making the intensity of a red component R small.  Then, the light emission spectrum characteristics in the visible area of the film illumination light of the light source are made relatively large on the short wavelength side and small on the long wavelength side compared to the white light source. Thus, at the time of picking up the images recorded on the film 2, the white balance is kept.
