Title: Nonlinear refractive-index measuring method in single mode optical fiber
Inventor: MATSUSHIMO ARUCHIGURIA
IPC: G01M11/02
Filed: 1995-05-30
Abstract: PURPOSE: To measure the nonlinear refractive index of an optical fiber by equipping only one of a pair of pulses with such a power as to cause a nonlinear effect inside the fiber, and measuring the phase shift between the two pulses of the pair. CONSTITUTION: A series of pulses are emitted by a laser L, passed through a variable damper AV1, and divided into two identical pulse trains by a coupler C1. The two pulse trains are transmitted in the opposite directions along a loop AS, and one of them is damped largely by a variable damper AV2 before coming into a fiber F. Another pulse train passes the polarization control device PC2, which compensates the complex refraction of the loop AS, and it goes out from the port O1 of the coupler C1 with the power possessed by pulses which are re-coupled after transmission along the loop. The pulses returned to the coupler C1 have the same intensity, but only one of them exhibits a vital phase shift owing to self-phase modulation.

Title: Fire extinguishing nozzle
Inventor: NAKAMURA MASAYUKI
IPC: A62C31/03
Filed: 1990-06-13
Abstract: PURPOSE:To enable atomized water to be jetted equally from the center to the outer side in jetting the atomized water by providing a first water path having a length from the proximal end side of a first water hole to the front end side of a second water hole between a body tube and a switch tube, and a second annular water path provided through a partition plate having the width shorter than the length of the second water path hole from the fist water path to be opened to the front end of the switch tube. CONSTITUTION:Fire extinguishing liquid W in a primary side flow path 12 flows from a first water hole 17 through a first water path 25. A portion of the liquid enters a secondary side flow path 13 through an eccentric spiral hole 18 and the other portion enters a secondary side flow path 13 and second water path 26 through a second water hole 19. The fire extinguishing liquid W flowing through the spiral hole 18 increases the flow speed at the eccentric spiral hole 18 to get a strong turning force since pressure is hardly produced on this side of a jet port 14. Thus, since the fire extinguishing liquid W becomes a vortex flow, the liquid W is atomized and diffused when it is jetted from the jet port 14.

Title: Ink jet head with temperature-controlling function
Inventor: TAKADA NOBORU
IPC: B41J2/055
Filed: 1981-09-30
Abstract: PURPOSE:To enable the supply of stable ink particles onto a recording paper sheet by a simple constitution wherein an ink jet head jetting ink particles is provided with a normal temperature characteristic thermistor having a function of self-control of temperature. CONSTITUTION:At the time when a power source is made, a normal temperature characteristic thermistor 4 is at the same temperature with the room temperature, i.e. below the Curie temperature, and its resistance value is small. Accordingly, the thermistor 4 starts to generate a heat, and when the temperature rises above the Curie temperature, the resistance value increases sharply. Thereby a current value is decreased and thus the temperature of the thermistor is constantly maintained at a prescribed level. When this Curie temperature is set at a desired temperature of ink, the ink can be kept constantly at a prescribed temperature by the normal temperature characteristic thermistor 4 arranged so that it holds ink jet nozzles 3 between. The viscosity of ink is thereby kept unvaried, and thus stable ink particles can be formed constantly.

Title: Tungsten carbide-base cemented carbide for cutting tool
Inventor: YOSHIMURA HIRONORI
IPC: B23B51/00
Filed: 1986-07-02
Abstract: PURPOSE:To improve chipping resistance by incorporating VC together with Co at a specific ratio into WC and confining the grain size of a hard dispersed phase to a specific fine range. CONSTITUTION:This cemented carbide contains, by weight, 5-20% Co and 0.2-10% VC, consists of the balance WC and has the fine structure in which the average grain size of the hard dispersed phase constituted of components except Co is 0.2-1mu. The alloy has particularly excellent chipping resistance and excellent wear resistance as well. The Co forms a binding phase in said alloy and is indispensable to assure the toughness of the alloy. The toughness is not enough if the content thereof is <5%, while the wear resistance is low if the content exceeds 25%. The VC contributes to the remarkable improvement in the chipping resistance without impairing the wear resistance. The desired effect is not obtainable if the content thereof is <0.2%, while the wear resistance is low if the content exceeds 20%. It is technically difficult to form the hard dispersed phase to <0.2mu average grain size, while the chipping resistance is sharply deteriorated if the grain size exceeds 1mu.
