Abstract: PURPOSE:To obtain the subject compound used as an intermediate for a silane coupling agent, a raw material of a resin, etc., with decreasing unreacted allyl alcohol content by distilling a reaction product containing allyl ester in the presence of water. CONSTITUTION:Methyl (meth)acrylate, etc., and allyl alcohol are mixed in the ratio of 1.5:1, and a small amount of hydroquinone monomethylether is added to the mixture. Sodium methylate is continuously added to the mixed liquid at 78-100 deg.C under agitation and put to react for 25-30 hours, while continuously distilling off secondary produced methyl alcohol. The reaction is stopped when the concentration of allyl alcohol in the reaction mixture reaches below 3.5wt.%. Then, 0.001-5wt.% water is added to the reaction mixture, which is distilled at 82-110 deg.C to efficiently obtain the objective allyl ester [e.g.; allyl (meth)acrylate, etc.] with decreasing amount of allyl alcohol which has not reacted and left in the mixture.

Filed: 1987-05-18
Abstract: PURPOSE:To simplify the structure and to reduce the manufacturing cost by providing a shape memory alloy, and linking it mechanically so that the shape restoration force of the alloy acts in the direction to release the switch. CONSTITUTION:When an excessive current flows to a motor 11 owing to an overload and the like, the Joule heat by the excessive current heats a shape memory alloy 9 up to the temperature area to generate the shape restoration force of the alloy 9, contracts the alloy 9 to restore to the memorized length, and the first contact 6 is pulled in a specific direction.

Title: Fiber reinforced metal and its production
Inventor: SAKAI YOSHIBUMI
IPC: C22C47/00
Filed: 1990-05-09
Abstract: PURPOSE:To improve strength in the direction orthogonal to a fiber direction by impregnating a molten Al alloy containing specific amounts of Ni with a group of continuous fibers, where Ni layer is formed on respective outside peripheries of the fibers, and performing high pressure casting. CONSTITUTION:The outside periphery of a continuous fiber of oxide, carbide, or carbon is previously coated with Ni layer. A molten Al alloy containing 0.5-10.0wt.% Ni is impregnated with a group of the continuous fibers coated with Ni layer mentioned above, and high pressure casting is done to solidify them. A part of the Ni layer as coating becomes Al2Ni, and this position becomes the origin and an Al2Ni whisker grows radiately in the direction orthogonal to a fiber direction. As a result, an acicular crystal consisting of Al-Ni intermetallic compound is liable to grow in the direction orthogonal to the fiber direction because of the affinity action for the Ni in the molten Al alloy, and a three-dimensionally complicated structure can be provided and strength can be increased.

Filed: 1986-05-26
Abstract: PURPOSE:To make assembly accurate by fixing a fiber guide to an optical fiber with solder and further, fixing the optical fiber itself to a stem with thermal shield consisting of cobalt glass that has the low thermal conductivity. CONSTITUTION:When an optical fiber 14 is fixed with solder, cobalt glass 13 is so located between a stem 2 and the optical fiber 14 as a thermal shield that the heat for soldering is not conducted to the stem 2 whose thermal capacity is large and such a state of thermal conductivity facilitates to carry out soldering with a handy compact soldering gun. In addition, when the optical fiber is fixed to a positioning pin 16, a relative position of both a laser diode chip 9 which is fixed on a pedestal 7 of the stem 2 through a submount 8 and the positioning pin 16 does not change with the variations of heating. Accordingly, there is no change in a state of the laser diode chip 9 before carrying out soldering as well as in a state of optical axis alignment by bending operation of the positioning pin 16 and an initial optical linkage being set at high level is maintained even after performing soldering works. Thus, its high optical linkage results in greater accuracy of assembly.

Title: Sunglasses not coming into contact with face
Inventor: MAEDA MASAYUKI
IPC: G02C3/02
Filed: 1994-04-19
Abstract: PURPOSE:To make it possible to move only the part of lenses and to easily and temporarily attach and detach the lenses by forming the sunglasses in such a manner that the lenses do not come into contact with the parts of the face, such as the nose and the forehead, by using fixing parts for fixing to the head as supports. CONSTITUTION:The sunglasses are so formed that the lenses 2 do not come into contact with the parts, such as the nose and the forehead, by using the fixing parts 1 for fixing to the head as the supports. The conventional sunglasses come partly into contact with the parts of the faces, such as the nose and the forehead. A user, therefore, feels uncomfortability in the case of sweating. Since such sunglasses are merely put on the nose or the ears, the sunglasses slip or come off when the user faces downward or moves vigorously in some cases. The iterative action to attach and detach the sunglasses at the time of passing tunnels during driving of vehicles is laborious. The fixing parts 1 and the lenses 2 are, thereupon, formed movable and the mounting parts 3 are held immobile by rubber, etc., so that the fixing parts 1 are inserted to the head part. Wearing of the sunglasses without contact with the face is thus possible.
