IPC: H01L49/02
Filed: 1984-04-06
Abstract: PURPOSE:To control disposition of a monomolecular film or a monomolecular multilayered film in two dimensions by forming a pattern of a monomolecular film or a monomolecular multilayered film after scanning the surface of the base with ion beams under the environment of no gas existence. CONSTITUTION:With a glass substrate 1-1 as a base, an Si injected layer 1-2 of 50Angstrom  depth is formed in accordance with a pattern by scanning Si ion beams on the surface. Then, using a chloroform solution of stearic acid of 5X10<-3>mol/l, a monomolecular film of the stearic acid is formed. This monomolecular film of stearic acid is formed, at first, by submerging the base to the bottom of water, then, after a film is developed, with a pulling up speed of 2cm/min and a surface pressure of 35dyne/cm. The monomolecular film 1-4 is formed in accordance with the pattern, on the area of the ion injected layer 1-3 but not formed on the other area of 1-2. Thus, by changing nature of the base using ion beams, the formation of a monomolecular film or a monomolecular multilayered film on the base in accordance with a pattern is made possible.

Title: Connecting structure for optical waveguide and optical fiber
Inventor: KOMATSU MASASHI
IPC: G02B6/122
Filed: 1988-03-22
Abstract: PURPOSE:To miniaturize a device and to improve reliability by directly mounting an optical fiber to a waveguide substrate by adhesive agent. CONSTITUTION:A first groove 21 is formed in the roughly vertical direction against a linear optical waveguide 12, and the end face of the optical waveguide 12 is exposed on the wall surface for forming this first groove 21. A second groove 22 for mounting an optical fiber 18 is formed in the roughly vertical direction against a first groove 21, that is, in the same direction as the optical waveguide 12. The optical fiber 18 is mounted in a second groove 22 so as to adhere closely to an optical signal incident end face, and in such a state, a second groove 22 is filled with an adhesive agent. Accordingly, optical and mechanical connection of the optical waveguide 12 and the optical fiber 18 is maintained stably, and there is no fear of causing a peeling-off in the connecting part. Also, since a thermal expansion coefficient of a waveguide substrate 11 and a thermal expansion coefficient of the optical fiber 18 are about the same, even if this phase modulator is used in the environment in which a temperature fluctuation is large, it is not feared that the optical coupling efficiency in the connecting part deteriorates.

Title: Viscous damper
Inventor: WATANABE KAZUYUKI
IPC: F16F9/06
Filed: 1989-03-20
Abstract: PURPOSE:To reduce resistance of a viscous fluid as much as possible so as to stabilize damper property by arranging a pressure absorbing body by which volume is flexibly varied by external pressure in a closed region which is closed by a wall surface in a case and by a fixed body, and which is situated close to the moving edge of a moving body. CONSTITUTION:When a moving plate 4 is moved to the right, in a closed region A on the right corner that is closed by an internal wall surface of a case 1 and by a fixed plate 3, resistance is generated in a viscous fluid 2 being pushed by an edge surface of the moving plate 4, whereby a tube 31 on the right corner is contracted, and the resistance is absorbed thereby. By means of the movement of the moving plate 4, negative pressure is generated in a closed region on the left corner, whereby the tube 31 of left corner is expanded, and the negative pressure is offset. Contraction and expansion of the tube 31 are repeated in reciprocating motion of the moving plate 4, during which reaction to the moving plate 4 is reduced as much as possible. Damper property is thus stabilized.

Abstract: PROBLEM TO BE SOLVED: To prevent a foot of an elevator passenger from being pinched in the gap to the peripheral wall varying with varying inclination angle of an incline elevator shaft resulting from the passenger placing his foot on the edge of the floor surface carelessly by dissolving the risk that the elevator passenger places his foot on a rising edge part. SOLUTION: A foor body 2 to keep horizontal attitude in such a way that the inclination angle of the floor surface 3 relative to the surface of the peripheral wall 1 of a car elevating and sinking in an incline elevator shaft varies with varying inclination angle of the shaft, is installed in the fit-in condition in the peripheral wall 1. A rising edge part 7 is provided along the peripheral edge of the floor body 2 and arranged protrusive upward from the floor surface 3. Therefore, the passenger having got on the elevator is guided so as to stand on the floor surface 3 apart from the rising edge part 7. This constitution dissolves such inconvenience that the passenger places his foot carelessly on the edge of the floor surface 3 to cause the foot to be pinched in the varying gap between the edge of floor surface 3 and the peripheral wall 1.  Also failure occurrence caused by falling of foreign matter from the gap to the peripheral wall 1 can be prevented.
