Title: Manufacture of active element added optical fiber parts
Inventor: HOSHINO SUMIO
IPC: G02B6/02
Filed: 1990-11-29
Abstract: PURPOSE:To add an active element in high density to a part contributing to light amplifying capacity so as to perform efficient light amplification, laser oscillation and light propagation by forming a glass coat formed at the diameter thinned part of an optical fiber by a solgel method. CONSTITUTION:An optical fiber 1 spun from preform formed of clad base material and core base material is superheated with a burner flame 3 through a quartz plate 2 and drawn to provide the optical fiber 1 with a diameter thinned part 4. Active element added sol 5 with a light amplifying active element added using a solgel method is prepared and applied to the diameter thinned part 4 of the optical fiber 1 to form a coat 51. The coat 51 is dried and gelled. The optical fiber is then heated and sintered to form a transparent glass coat 6. The active element can be thus added in high density to the part contributing to light amplifying capacity so as to perform efficient light amplification, laser oscillation and light propagation.

Title: Optical fiber cable
Inventor: TONERIKAWA RYOICHI
IPC: G02B6/44
Filed: 1994-12-09
Abstract: PURPOSE: To protect the internal optical fibers of the optical fiber cable by providing a jacket formed by winding a plastic tape whose surface is not smooth on a nonmetallic cable core and providing an external sheath thereupon. CONSTITUTION: On a nonmetallic cable core 21, a jacket 40 formed by winding plastic tape whose surface is not smooth, is provided, and the external sheath 50 is provided thereupon to obtain the united optical fiber cable. Then, when the jacket is formed on the cable core 21 by winding the plastic tape whose surface is not smooth, many gaps are formed between the core and jacket. In this case, air is present in the gaps. When an external force of cable compression, a shock, etc., is applied, the tape of the jacket deforms so that the gaps become smaller. At this time, air in the gap is compressed and escapes to an area where the external force is not applied by finding narrow gaps. Consequently, the tape of the jacket operates similarly to an air damper to absorb the shock, thereby protecting the internal optical fibers.

Title: Solid state laser device
Inventor: KUBA KAZUKI
IPC: H01S3/02
Filed: 1988-12-28
Abstract: PURPOSE:To improve the quality, efficiency of a beam inexpensively by forming an optical passage in a laser medium parallel to its surface, and cooling the laser medium from its surface. CONSTITUTION:A thin platelike laser medium 1 is excited by an exciting lamp 3 and a light collector 4 from its surface 1a, and part of an exciting energy is output of the medium as a laser beam 2 to be propagated parallel to the surface 1a via resonator mirrors 6, 7. Remaining exciting energy becomes heat in the medium 1, which is removed from the surface 1a with refrigerant 5. In this case, a square temperature distribution is generated in thicknesswise direction in the medium 1, a thermal lens is generated thereby, but the thermal lens is not generated in a direction parallel to the surface 1a of the medium. Since the medium 1 is cooled in a large area, efficient cooling is performed. Since the optical axis 2a of the laser beam 2 is parallel to the surface 1a of the medium, it is not affected by the influence of the thermal distortion or stress distortion of the surface 1a, but affected by the thermal lens effect of the thicknesswise direction of the medium 1, and easily corrected by an external optical element.

Title: Gas switchgear
Inventor: FUJITA MASAHIKO
IPC: H01H33/985
Filed: 1994-12-13
Abstract: PURPOSE: To heighten the gas pressure rise in an arc extinguishing chamber and increase breaking current capacity even at the time of opening a gas switchgear by forming a heat insulating layer in the inner wall face of at least the arc extinguishing chamber side inner wall faces of an electric field shield. CONSTITUTION: A heat insulating layer 51 is formed in the inner wall face of an electric field shield 5 installed in the peripheral part of a fixed contact 1 and fixed in and attached to a pedestal 2. In this way since the thermal conductivity of the shield 5 can be lowered without deteriorating the function of an electric field moderation of the shield, the rise of the gas pressure of an arc extinguishing chamber can be retained. As a result, an arc at the time of opening a gas switchgear is cooled by a high pressure gas and the shutting electric current can be increased. Moreover, the heat insulating property of the shield 5 attributed to the low thermal conductivity can be retained by using a fluororesin for the layer 51 and at the same time the current shutting function can be further improved.
