Title: Optical modulator
Inventor: KONO KENJI
IPC: G02F1/035
Filed: 1988-08-12
Abstract: PURPOSE:To suppress an increase in driving electric power and to enable fast, wide-band optical modulation by nearly equalizing the width of a center electrode to that of an optical waveguide and increasing the thickness of a buffer layer. CONSTITUTION:The thickness D of the buffer layer 2 is so set that the microwave effective refractive index of a substrate to a microwave signal for modulation applied to a coplanar waveguide electrode is close to the effective refractive index to light propagated in the optical waveguide 2. The width 2W of the center electrode 4 is nearly equal to the width of the optical waveguide 2 and the optical waveguide 2 is arranged below the center electrode 2. Therefore, even when the thickness D of the buffer layer is increased, deterioration in electric field intensity is suppressed small. Consequently, while the increase in the driving electric power of the microwave signal for modulation is suppressed small, the fast optical modulation is enabled.

Title: Strand joining method and splitting jig
Inventor: NAGURA YASUMI
IPC: H01R4/02
Filed: 1995-08-08
Abstract: PURPOSE: To provide a strand joining method where the mechanical strength of a joined part is not deteriorated and the conductive resistance is not increased by circumferentially working a groove of arbitrary width and depth on the inner circumferential surface of a splitting jig to which the strand is inserted from both sides, and applying the release agent on the inner surface. CONSTITUTION: In achieving the resistance welding, the impurities collected in a molten pool part 8 of a joining interface 7 are discharged in a clearance 11 between some parts of the element wires 10 as the burr 9 by allowing the current A to flow to a contact part which is the joining interface 7, and achieving the pressing to weld by applying the pressure B while the contact part is heated to the welding temperature. Most of the impurities are pushed out as the burr 9 out of the joined part with the pushing force C, and recognized to be formed in a groove part 6. No pores are present in the vicinity of the joined interface 7 to provide the sound condition. Because the release agent is applied to the groove part 6 and the contact surface with the strand 1, the welding is prevented between the strand 1 and a splitting jig 3 even if an unexpected trouble occurs during the welding.

Title: Low pressure mercury vapor electric discharge lamp and lighting system
Inventor: HONDA HISASHI
IPC: H01J61/35
Filed: 1994-08-29
Abstract: PURPOSE:To reduce generation of blackening of a low pressure mercury vapor electric discharge lamp of a rapid start type. CONSTITUTION:A low pressure mercury vapor electric discharging lamp comprises a tubular translucent air-tight container, e.g., a glass bulb 1, enclosing an electric discharging medium; a pair of electrodes 2 disposed at both ends of the bulb 1; and a transparent conductive coating composed of mainly metal oxide such as tin oxide, having conductivity by reducing a part thereof and added with a small quantity of an additive capable of stabilizing conductivity such as antimony. The content of the additive in the transparent conductive coating 4 is larger at both ends thereof than that in the center thereof. Consequently, in the transparent conductive coating 4, its resistance value is stabilized at the ends where a concentration of the additive is higher while its resistance value is not stabilized and reduced in the center thereof because of a lower concentration of the additive. As a result, resistance value distribution is closer to a theoretical V-shaped.

Title: Measuring device for distribution of grain size
Inventor: SHIMAOKA HARUO
IPC: G01N15/02
Filed: 1990-07-30
Abstract: PURPOSE:To achieve measurement with a high resolution by performing measurement in a state where a grain with a long diameter is eliminated from a laser beam emitting position along with measurement of normal diffracted/scattered light strength distribution and by calculating the entire distribution from both results. CONSTITUTION:A flow cell 1 has both an entrance 1a and an exit 1b and allows a suspended liquid to be flown into the cell 1. Then, when the flow of the suspended liquid within the cell 1 is stopped, the grain which is scattered uniformly within the suspended liquid starts to settle out, a larger grain settles out faster, and no grains which are larger than a grain diameter which is determined according to distance from an uppermost surface of the cell 1 at that position and sedimentation time at a position passing through a position where laser beam from a laser beam source 3 is emitted when a certain amount of time passes by after sedimentation of the suspended liquid. Therefore, strength distribution of the diffracted/scattered light which is measured in this state is not affected by a large grain and results in strength distribution of the diffracted/scattered light due to a small grain. Then, normal distribution of the entire sample grain is measured and both measurement results are added together to achieve measurement with a high resolution in a wide range of large and small grain regions.

Abstract: PURPOSE:To enable a reproduced image to be viewed as if the image moves in follow up to a visual point by casting a laser beam to a developed film, diffusing the beam through a screen and recording the information thereof on a hologram recording material. CONSTITUTION:The laser beam is cast to the film 3 developed to positive and the light 16 transmitted through this film is diffused through the transmission and diffusion screen 9. The hologram recording sensing material 12 is placed in front of this screen and a shielding plate 10 bored with a slit 11 is placed before this material. The hologram recording sensing material 12 is then moved laterally by as much as the aperture width of the slit 11 and a light source for reference light 17 is also moved according to the movement of the hologram recording sensing material at the time of recording. This movement is repeated and the hologram recording sensing material is developed. The virtual image of a subject is regenerated when the diffused illuminating light in parallel with the transverse direction is cast to the formed hologram. The virtual image appears always in the same visual line direction when the visual point is moved laterally along the hologram. The image is visible in follow up to the movement of the visual point in this way.
