Title: Optical multiplexer and demultiplexer
Inventor: SANO KOUICHI
IPC: G02B6/34
Filed: 1982-03-01
Abstract: PURPOSE:To decrease the number of sheets of nterference film filters by changing the incident angle of the 2nd time to wide band interference filters from the incident angle in the 1st time. CONSTITUTION:The rate of transmission attenuation of a long wavelength pass interference filter LWPF depends on incident angles and if the incident angle theta increases, the shielding wavelength deviates a short wavelength side. The same holds true of a short wavelength pass interference film filter (SWPF). Therefore, if the incident angle in the 1st time is set at theta, and the angle in the 2nd time at theta+alpha in the stage of using the SWPF and the incident angle in the 1st time at theta, and the angle in the 2nd time at theta alpha in the case of using the LWPF, the rays transmitted in the 1st time are reflected with the wide band interference film filter in the 2nd time, and can be separated from the transmitted rays. The rays of wavelenghts lambda1, lambda2, lambda3, lambda4 incident from an input optical fiber 1 are converted to parallel rays by a lens 30, and the parallel rays are made incident to the SWPF7. The rays of the wavelengths lambda3, lambda4 reflected there are made incident to a band pass filter (BPF) 63 of the transmission wavelength lambda3, and the ray of the wavelength lambda3 transmits through the BPF 63 and is outputted to an output optical fiber 23. The ray of the reflected wavelength lambda4 is outputted to an output optical fiber 24. On the other hand, the ray of the wavelength lambda1 of the rays of the wavelengths lambda1, lambda2 transmitted to the filter 7 is outputted to the fiber 21 and the ray of the wavelength lambda3 to the fiber 23, respectively.

Abstract: PURPOSE: To control the level when the deviation of an inflow quantity and an outflow quantity  may exist in a non-sensing zone, by means of giving a preseribed operation output.   
     CONSTITUTION: In a system of  cascade connection, a liquid level controller LC having a non- sensing zone as the first side, and a flow quantity controller FC as the second side, the liquid level  controller LC gives the deviation signal to the flow quantity controller FC as a flow quantity  measuring value fg by means of making the liquid level of a reserved tank RS into a measuring  value h, and of generatting the control output signal corresponding as the deviation of the measuring value and a liquid level set value hg. The liquid level controller LC makes a flow quantity (f  in) of the inflow liquid of the reserved tank RS into a sub-input signal, and the flow quantity controller FC makes flow quantity of the inflow liquid of the reserved tank RS into the measuring  value (f in), and by means of generating the control output signal corresponded as the deviation  with the set value fs, LC gives this to a flow quantity control valve FV. The liquid in the reserved  tank RS is flows out as (f out) according to the demand. When the liquid level h is entered in the  non-sensing zone, the controlling action corresponding as the deviation become null, and the control output is fixed at the value of straight before the liquid level h entering in the non-sensing  zone, thereby the liquid level is allowed to be stabilized.

     CONSTITUTION: A mixture of 100pts.wt. of a thermoplastic resin and 20W30pts.wt. of a thermosetting resin having a melting point of 60W180°C, is mixed with appropriate amounts of a blowing agent and a curing agent to form a well-dispersed moldable product in which the blowing agent has not been decomposed (slight decomposition may be admitted). Then, the resulting foamable product is heat-foamed to produce a desired foamed product. As the thermosetting resin an epoxy resin is used, as the thermoplastic resin an ethylene/vinyl acetate copolymer or a derivative thereof (such as an ionomer), and as the blowing agents those which are solid and decompose at a temperature higher than the softening point and the melting point of the resin components, such as dicyandiamide. This composition is formed into a moldable product such as sheet, for example, by extrusion, and the moldable product is then heat-foamed. Thus, foamed products with good dimensional stability can be easily produced.
