Title: Wave guiding path type light switch and manufacture thereof
Inventor: KAWAMATA SHIGERU
IPC: G02F1/313
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable wave guiding path type optical switch and a manufacturing method thereof. SOLUTION: The index of refraction of a high molecular polymer 28 arranged in a slit 27, which is formed across a core 23, in a crossing part 26 of a light wave guiding path 25 is changed by means of a refraction index control unit 31. When the index of refraction of the high molecular polymer 28 is substantially equal to that of the core 23, the light incident on the crossing part 26 from a branch path 25a of the light wave guiding path 25 permeates the high molecular polymer 28 in the slit 27 so as to be transmitted through a branch part 25c on the permeation side. When the index of refraction of the high molecular polymer 28 is different from that of the core 23, the light incident on the crossing part 26 from the branch path 25a in the light wave guiding path 25 is reflected on the inside wall of the slit 27 so as to be transmitted in the branch path 25b on the opposite side.

Title: Signal multiplex recording method and its recording and reproducing device
Inventor: AMADA NOBUTAKA
IPC: G11B5/02
Filed: 1989-11-15
Abstract: PURPOSE:To ensure the reproduction level of a PCM audio signal and to attain the signal multiplex while avoiding disturbance onto a video signal by taking a recording level of a video signal, a PCM audio signal and an FM audio signal and the size of a magnetic gap of a magnetic head for the PCM audio signal into account. CONSTITUTION:A PCM audio signal is recorded on a same track by a PCM audio signal head 2 and then finally a video signal is recorded on the same track overlappingly with a video head 3. Since an FM audio signal has the lowest recording frequency and the size G1 of the magnetic gap of an FM audio signal head 1 is set longest in matching with the recording frequency, the signal is recorded up to the deepest layer of a magnetic layer 8a of a magnetic tape 8. The recording frequency of the PCM audio signal is higher than that of the FM audio signal and the size G2 of the magnetic gap is selected shorter than the size G1 and then the depth of the recording reaches only the intermediate layer of the magnetic layer 8a. The size G3 of the magnetic gap of the video head 3 is selected short in matching therewith. Thus, the high definition PCM audio signal is recorded multiply without giving disturbance onto the video signal.
