Title: High isolation mixing distributer
Inventor: KATO KEISUKE
IPC: H04N5/00
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent a mixed wave from being leaked to an antenna without the use of a band trap by providing an isolation adjustment circuit and a reactance matching circuit before and after a mixing distribution circuit to the distributer. SOLUTION: Signals received from input terminals 11, 12 are mixed by a mixing distribution circuit 14 via an isolation adjustment circuit 13 and the result is given to a reactance matching circuit 15. The circuit 15 is used to match the output impedance so as to eliminate a reflection wave from a mixture output terminal 16, and the circuit 13 adjusts a variable resistor and a variable capacitor to turn an isolation frequency (f) to a mixed wave (e.g. a signal wave received from the input terminal 12) so as to isolate signals between the terminals 11, 12. Thus, the mixing distributer has a complete isolation characteristic at the specific frequency (f), and even when a signal with the specific frequency is given either of the terminals 11, 12, the signal does not appear at the other terminal.

Abstract: PURPOSE:To obtain a superpower proportional to the spacing of a pair of electrodes by providing a plasma guide pipe for leading plasma flow from a gas space to a space part between a liner and a pair of electrodes and then allowing the bore of the plasma guide pipe to communicate with an air gap part without any step, and hence making uniform the plasma density within the spacing the pair of electrodes. CONSTITUTION:A cylindrical plasma guide pipe 24 is provided between a protection plate 13 and an insulation joint 23 and the inner diameter of the plasma guide pipe 24 is made equal to the spacing a of a pair of electrodes 6A and 6B. Therefore, even if the inner diameter of a gas space 2 is smaller than a spacing a, plasma flow spreads also in the radial direction within the pipe while it advances the lower part within the plasma guide pipe 24 and then plasma density becomes uniform inside an air gap part 9 when the plasma flow reaches the air gap part 9, thus enabling the electromotive force obtained between the pair of electrodes 6A and 6B to be proportional to the spacing length d and hence improving generation efficiency.

Title: Functional plastic optical waveguide
Inventor: YOSHIMURA AKIYUKI
IPC: G02B6/12
Filed: 1990-05-02
Abstract: PURPOSE:To obtain the amplification and oscillation effect of high efficiency over a near UV to near IR region by adding a material having fluorescence to a polymer contg. at least one kind of halogen and deuterium. CONSTITUTION:The material having the fluorescence is added to the polymer contg. at least one kind of the halogen and deuterium. This polymer is formed by halogenating or deuterating the hydrogen of a side chain. The polymer is, therefore, small in the higher harmonic wave light absorption between the carbon and the hydrogen existing in the near IR region and is subjected to long wavelength shifting, by which the loss of the material itself is lowered. The high-efficiency operation is executed in the visible to near IR region in this way. The oscillation and amplification functions of the good efficiency are exhibited even in the wavelength region of particularly 1 to 1.6 mum where the conventional plastic optical elements are not practicable at all.

Abstract: PURPOSE:To attain back word compatibility being used for protecting a recording data on a conventional recording medium by enabling write only in a high density recording medium in which a servo information is written, prohibiting write in the conventional recording medium, and reproducing. CONSTITUTION:A detection means 5 to detect the presence/absence of a servo information in a recording medium, and a write inhibiting means 8 that inhibits a recording to a recording medium form which no servo information is detected are provided on the high density recording medium. In a high density recording medium, a servo information is written preliminarily at the time of formatting. Since no servo information is not written in the conventional recording medium, when no servo information is detected in said detection, the recording medium is judged to be a conventional one, and the write is inhibited by detecting the presence of the servo information. Therefore, such a back word compatibility that guarantees the protection of data for the conventional recording medium can be attained.
