Title: Fluid sealed mount device
Inventor: KATAYAMA MOTOHIRO
IPC: F16F13/22
Filed: 1987-07-27
Abstract: PURPOSE:To spread a frequency band of input vibration able to be isolated by elastically connecting respectively an intermediate member to the first supporter and the intermediate member to the second supporter while closing both ends of the intermediate member and providing the first and second rubber elastic members which form internal space containing inner side space of the intermediate member. CONSTITUTION:By fluidizing non-compressive fluid through a throttle passage 48, an input vibration in a low frequency band set in the passage 48 is well damped as obtained in the past. While an intermediate member 18 is elastically connected to the first supporter 10 and the second supporter 12 respectively through the first and second rubber elastic members 20, 22. Consequently in a frequency band higher than the resonance frequency band of the intermediate member 18, the absolute spring constant of a mount device in the opposed direction of both the supporters 10, 12 can be substantially reduced. Accordingly, the input vibration is well isolated in the frequency band higher than the resonance frequency band of the intermediate member. While being based on the deformation or the displacement of a movable plate 60, the absolute spring constant in the resonance frequency band of the intermediate member 18 is well suppressed from increasing.

Title: Satellite channel simulation device
Inventor: UEDA KAZUNORI
IPC: H04B7/212
Filed: 1989-07-19
Abstract: PURPOSE:To simplify a circuit scale by processing a digital signal outputted from a simulated VSAT as it is. CONSTITUTION:Outputs from a simulated VSATs (subminiature earth station) 5(1)-5(N) are retarded by the time corresponding to a distance from each VSAT being an simulated object till a satellite at a data delay circuit 4 and respective distance signals are inputted respectively to unique word detection circuits 2(1)-2(N). A synthesis circuit connected to a unique word detection circuit detecting a unique word 11 in a data inserts a detection flag 13 to the rear part of the data. When plural packet data are hourly coincident, a collision data elimination circuit 1 informs the discrimination of the presence of collision to inform a data processing section 6 by eliminating forcibly the unique word detection flag 13. Thus, the test signal sent from a simulated earth station is processed without modifying the digital signal, then the circuit constitution is simplified.

Title: Method and circuit for detecting abnormality of displacement detector
Inventor: NAGAI MAKOTO
IPC: G01B21/02
Filed: 1984-09-07
Abstract: PURPOSE:To make it possible to monitor abnormalities caused by many faults simultaneously without processing detected signals and the like, by judging abnormality when the level of the detected signal in each phase is located in an abnormality detecting region between the high and low levels, which are set so as to hold a reference level common to all the detected signal. CONSTITUTION:Under the normal state, a high level La and a low level Lb are set adequately. The outputs (a) of comparators 32A and 32B and the output (b) of comparators 33A and 33B do not become a high level at the same time. Therefore warning (w) is not outputted. Meanwhile, when phases are deviated due to abnormality in a scale, mechanical trouble and the like, the timing in an abnormality detecting region is delayed or advanced. Therefore, signals Sa and Sb are synchronized, the outputs (a) and (b) become the high level simultaneously and the warning (w) is issued. When the amplitude of the detected signal becomes small due to the contamination of the scale, abnormalities in optical and electrical systems and the like, the remaining period in the abnormality detecting region becomes long, the output (a) and (b) become the high level simultaneously and the warning (w) is outputted.

Filed: 1982-10-28
Abstract: PURPOSE:To vary the focal length of a lens at a high speed by providing a transparent electrode film whose resistivity distribution is proportional to the square of the distance from a specific point on one of facing surfaces of light transmissive material on the surface.

Title: Wavelength selection switch
Inventor: AJISAWA AKIRA
IPC: G02F1/31
Filed: 1987-07-27
Abstract: PURPOSE:To extract an optional wavelength selectively from plural multiplexed different wavelengths by forming a 1st optical waveguide and (n) optical waveguides which have a wider band gap than a multiple quantization well and nearly equal effective refractive indexes. CONSTITUTION:When an electric field Ej is applied to the total reflecting surface (MQW reflection part) of an (i)th intersection part, the angles between an optical waveguide 14 for input and the MQW reflection parts 11-13 are so set as to cause total reflection at a rate (-DELTAn0/n) of refractive index variation. Here, a wavelength lambdaj with which (-DELTAn0/n) is obtained at the time of the electric field Ej can be selected by the refractive index variation of the MQW by selecting (-DELTAn0/n) properly. Therefore, only a light signal with the wavelength lambdaj is reflected totally at the (i)th intersection part and led out of the intersection waveguide selectively. Light signals with other wavelengths are passed as they are because the total reflection conditions are not satisfied by the electric field Ej. Further, electric field intensity different from the Ej is applied at other intersection parts to lead out signal light with a wavelength other than lambdaj which satisfies the total reflection conditions.
