Title: Protective device for elevator cable
Inventor: IMAMURA TOSHIRO
IPC: H02G11/00
Filed: 1989-02-22
Abstract: PURPOSE:To prevent optical fibers from being broken or from causing transmission loss by arranging a protective member to control the bending diameter of a composite cable to the bending position such as the suspension stop section or excess length processing section of the composite cable. CONSTITUTION:In laying a cable for an elevator a cylinder member 18a, the protective member 18, is arranged to a suspension stop section 12 and an excess length processing section 16 of a composite cable 17. Through the circular surface of this cylinder member 18a the composite cable 17 is bent, while a corner member 18d is arranged to a corner section 19 of the building against which the composite cable 17 abuts so that the composite cable 17 will abut against the circular surface of the corner member 18d and will not be directly brought into contact with the acute-angled corner section 19 of the building. Consequently in laying the composite cable 17, the bending diameter at the bending position where the composite cable is called for being bent is controlled by the circular surface having a curvature without phototransmission loss of the protective member 18. The breakage or transmission loss of optical fibers can thereby be prevented.

Title: Method and apparatus for measuring refractive index/ temperature
Inventor: YATAKI MASAMICHI
IPC: G01N21/41
Filed: 1995-02-08
Abstract: PURPOSE: To correctly measure the temperature, refractive index and physical amount of an object to be measured in a simple constitution, by comparing a branching ratio obtained with the use of two different measuring wavelengths with refractive indexes and calibration rates of the refractive index and temperature obtained beforehand for the measuring wavelengths, and obtaining a correlation of the refractive index and temperature. CONSTITUTION: When signal lights of different measuring wavelengths λ1 , λ2 are sent into an optical branching device 10 from light emitting devices 30A, 30B, a part or the whole of the lights move to optical fibers f2 , f1 at the opposite side due to the refractive index of an object to be measured (e.g. wax including oil) present in the periphery of an optical coupler 12, to be separated again to wavelengths λ1 , λ2 by spectroscopes 35, 36 and detected by photodetectors 31, 33 and 32, 34, respectively. Branching ratios R1 , R2 are calculated by a signal-processing means. The branching ratios R1 , R2 are compared/processed with previously obtained refractive indexes and temperature calibration data at the two measuring wavelengths λ1 , λ2 .  Two pairs of relations between the temperature and refractive index (the amount of oil represented by the refractive index) of the object (wax) to the branching ratios R1 , R2 are accordingly obtained.

Title: Power source switching circuit
Inventor: FUJIMORI SHIGEO
IPC: H03K17/62
Filed: 1978-04-13
Abstract: PURPOSE: To supply constant voltage to load by means of a constant-voltage source with comparatively little capacity, by connecting switching transistors, which install resistances for controlling currents to the bases, among the constant-voltage source and a plurality of load circuits.  
     CONSTITUTION: Switching transistors 14, 15 are connected among a constant- voltage source 11 and the load 12, 13 of VHF, UHF receiving circuits, etc., and switching control voltage is fed to these bases of the transistors through resistances 16, 17 for controlling currents, thus selectively operating the transistors. The resistance value R of the resistances 16, 17 for controlling currents at that time is selected at value obtained by an expression R≥Vs-(VO+VBES)/I. Consequently, constant voltage can be fed to load circuits, which load currents sharply differ, even if using the constant-voltage source with little current capacity that constant voltage can be gained only in comparatively narrow ranges, thus the constant-voltage source can be miniaturized and be produced in little capacity.

Title: Light emitting diode and manufacturing method
Inventor: KURAHASHI TAKANAO
IPC: H01L33/30
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To improve outgoing emission efficiency by forming a space contg. no crystal in a region in a lower part of an upper electrode. SOLUTION: A circular space 80 is formed which is vacuum or filled with an atmosphere gas at bonding and contains no III-V compd. semiconductor crystal. A light emitted toward a GaAs substrate 1 is reflected to the surface of a light emitting diode chip by a RBR 3. A light emitted toward a GaP substrate 8 is reflected to the surface of this chip because of the refractive index difference between the space and substrate 8 in addition to DBR 3. Among lights emitted from a light emitting layer, the light from a cap layer 7 to the space 80 is transmitted about 70% and the transmitted light is reflected about 30% and the transmission and reflection are repeated. Since no absorption layer exists, the light is almost propagated to a second transparent semiconductor substrate 8 (GaP). Thus, the outgoing emission efficiency is improved.
