Title: Surface hardening build-up welding method
Inventor: UEDA MASATO
IPC: B23K10/02
Filed: 1980-04-10
Abstract: PURPOSE: To form a welded metal of high hardeness efficiently on the surface of  base metals by supplying welding materials in the form of powder by means of an  inert gas as a carrier gas into the plasma arc.  
     CONSTITUTION: If cooling water 18, 21, a shielding gas 24 and a plasma gas 19 are beforehand supplied, and voltage is increased gradually by closing the circuit of a pilot arc power source 16, the arc is generated between a nonconsumable electrode 11 and a pilot arc electrode 12. Next, when the circuit of a welding power source 17 is closed, the arc of DC reverse polarities is generated between the base metals 10 and the nonconsumable electrode 11. If the arc voltage is gradually increased and the flow rate of the plasma gas 19 is increased, the plasma arc 20 is generated between the base metals 10 and the nonconsumable electrode 11. Thereupon, when powder mixture 22 is supplied together with an inert gas to a powder supply nozzle 13, the powder mixture 22 enters the plasma arc and the alloy powder of a low m.p. melt-sticks on the base metals 10, then the carbide powder of a high m.p. disperses and enters the inside of this deposited metal, thereby forming a build-up weld zone 23.

Title: Side light type planar light source unit and liquid crystal display device
Inventor: OKAWA SHINGO
IPC: G02F1/1335
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To make the quantity of outgoing light uniform by making the illumination light emitted from a light source incident through an end surface of a rod-like member and emitting the light from a surface along the flank of a planar member formed by repeating a projection consisting of a couple of oblique surfaces in the longitudinal direction. SOLUTION: A light guide plate 11 is formed into a tip-truncated wedgewise sectioned shape by molding, for example, an acrylic resin of a transparent member by injection and the illumination light L1 of a primary light source 12 is made incident from the incident surface 11A. Consequently, the light guide plate 11, while propagating the illumination light L1 made incident from the incident surface 11A into the inside, emits a component of less than the critical angle from a outgoing surface 11B. Further, the light guided plate 11 has projections formed by repeating a couple of oblique surfaces 18A and 18B in the longitudinal direction of the incident surface 11A as shown by a partially enlarged part A of the incident surface 11A. Here, the projections is formed by directly connecting the couple of oblique surfaces 18A and 18B.  Then the directivity of the illumination light L1 is corrected to a direction perpendicular to the incident surface 11A.

Title: Magnetic recording medium
Inventor: SUEYOSHI TOSHINOBU
IPC: G11B5/716
Filed: 1983-03-20
Abstract: PURPOSE:To improve the recording and reproducing capability of a magnetic recording medium by installing a different kind of magnetic layer using a specific magnetic powder as the recording element between a magnetic layer in which metallic platy magnetic powder made mainly of Co is contained, and the base. CONSTITUTION:A magnetic layer (lower layer) using granular magnetic powder having coercive force of <=200 oersted as the recording element is formed on a base and another magnetic layer (upper layer) using metallic platy magnetic powder having mean grain size of <=0.3mum and made mainly of Co as the recording element is formed on the lower magnetic layer. Since the recording element of the lower layer is granular and made of magnetic powder of a low coercive force of <=200 oersted, the magnetic permeability of the lower layer becomes larger and its recording and reproducing outputs are improved. When metallic magnetic powder of >0.3mum in mean grain size is used for the upper layer, the original magnetic characteristic of this kind of metallic powder cannot be exhibited and improvement in the recording and reproducing characteristics by installing the lower layer cannot be expected.

IPC: G02B6/13
Filed: 1983-03-19
Abstract: PURPOSE:To form a thin film optical structure such as an optical waveguide, a waveguide lens, or the like accurately as prescribed values by monitoring the reflected light or the transmitted light of an optical beam to detect elements of the structure which is formed and conrolling a device, which irradiates the optical beam, on a basis of this detection signal. CONSTITUTION:A luminous flux 13 is irradiated to the whole of the surface of a substrate 1 immersed in a molten liquid 2, and a part of this luminous flux is reflected and is returned to a lens 4 and is led to a detector 7 through a beam splitter 6, and the luminous flux transmitted through the substrate is condensed by a lens 5 and is made incident to a detector 8. The surface of the substrate 1 is heated locally by the luminous flux 13, and ion exchange advances to increase the refractive index near the surface, and a waveguide is formed. Since the reflection factor and the transmittivity of the luminous flux 13 on the surface of the substrate are changed when the refractive index of the surface is changed, the variance of the intensity of the reflected light or the transmitted light is observed by the detector 7 or 8 to monitor the state of the waveguide at this time. The intensity of the monitor light of the reflected or transmitted light of the optical beam at the time, when said waveguide is formed into a pescribed state, is preliminarily detected by calculation or experiment, and the signalf rom the monitor is observed to form the waveguide with accurate values.
