Title: Electromagnet
Inventor: TANAKA TAKANOBU
IPC: H01H73/36
Filed: 1990-08-14
Abstract: PURPOSE:To reduce current consumption of an exciting coil and decrease fluctuation in operating voltage by reducing an area of the contact between a stopper portion of a plunger and the inner circumferential surface of a plunger inserting hole of a yoke. CONSTITUTION:When an exciting current flows in an exciting coil 1, a yoke 2 and a plunger 4 constitute a circuit, to generate attraction force for attracting the plunger 4 into an inner hole la of the coil 1, whereby the plunger 4 is driven left against spring force of a return spring 6. Because of a small area of the contact between a stopper 4a and the inner circumferential surface of a plunger inserting hole 3, the plunger 4 can be attracted even if a large exciting current does not flow in the coil 1, thus reducing current consumption of the coil 1. Furthermore, if the attraction force between the stopper portion 4a and the inner circumferential surface of the plunger inserting hole 3 is weakened, an effect exerted on an operating voltage of an electromagnet device is reduced, thus decreasing fluctuation in operating voltage.

Abstract: PURPOSE:To make it possible to specify the cause of the increase in the amount of optical transmission loss and to compute the amount of optical transmission loss accurately at the arbitrary wavelength other than the wavelength under test by using the lights having a plurality of the different wavelengths, and measuring the amount of the optical transmission loss for every light in each wavelength. CONSTITUTION:An optical switch 3 appropriately selects the pulse lights having the different wavelengths which are emitted from optical pulse testers 4 and 5. The light is cast into an optical fiber 1 to be measured through a light splitting device 2. The Rayleigh scattering light from the fiber 1 is sent into the testers 4 and 5 again. The amount of the optical transmission loss is remotely measured for every wavelength of the pulse light and sent into a data analyzer 6. The lights having a plurality of the different wavelengths are used. The amounts of the optical transmission losses in both cases of the case wherein the cause of the increase in the amount of the optical transmission loss is not present in the fiber 1 and the case wherein the increase cause is present are measured. Thus the increasing amount is computed. In this way, the ratio between the increasing amounts of the lights having the different wavelengths is computed, and the increase cause is specified. At the same time, the increasing amount of the optical transmission loss at the arbitrary wavelength can be accurately computed.

Title: Semiconductor light emitting device
Inventor: ISHIKAWA MASAYUKI
IPC: H01L33/08
Filed: 1990-08-20
Abstract: PURPOSE:To realize high efficiency light emission wherein the luminescent point is small, by making the band gap of a conductor substrate smaller than the energy of the luminescent wavelength, and making the distance between a semiconductor substrate and an active layer smaller than the distance between the active layer and a luminescent surface. CONSTITUTION:The energy gap of an InGaAlP active layer 103 is smaller than those of clad layers 102, 104, and mixed crystal composition is set. The distance from the luminescent surface of the active layer 103 is set to be small as compared with the distance from the GaAs substrate. A part of the generated light in the active layer 103 travels toward the substrate side, and a part of the generated light travels toward the luminescent surface side. When the energy of the light which reaches the GaAs substrate 101 is smaller than the energy gap of the substrate, the light is absorbed by the substrate. Hence the light emitted toward the substrate side is not outputted to the outside, so that a small luminescent point can be obtained. When InGaAlP is used as the active layer material, superior epitaxial crystal can be grown in the wide range of green, yellow, orange and red. Thereby, a double hetero structure inevitable to high efficiency light emission can be easily formed while lattice matching to GaAs is maintained. As the result, high efficiency light emission of a small luminescent point can be realized.
