Title: Noise filter and its production
Inventor: TAKAHASHI AKIRA
IPC: G02F1/015
Filed: 1994-03-30
Abstract: PURPOSE:To passively remove the naturally released light generated from an optical amplifier by setting the carrier life of multiple quantum well layers at a specific value or below. CONSTITUTION:This noise filter is constituted by forming the multiple quantum well layers having a supersaturation absorption characteristic of light on a semiconductor substrate and the carrier life of the multiple quantum well layers is set at <=100 picosecond. The noise filter of reflection arrangement having such multiple quantum well layers has the constitution shown in the Fig. Namely, the light propagating in a fiber 10a is taken out as parallel light beams in the space by a collimator 11. These parallel light beams are converged into the low-temp. grown Be-doped InGaAs/InAlAs multiple quantum well layers 15 of a reflection type on the InP substrate 14 by a corner mirror 12 and a condenser lens 13. The reflected light beams are admitted again into the fiber by the same travel. The operation as the passive noise filter of the light pulse train of a high-bit rate is made possible by this constitution.

Abstract: PROBLEM TO BE SOLVED: To provide a humidistat which is so arranged as to be capable of rationally performing indoor humidification and dehumidification. SOLUTION: A humidistat 500 performs humidification and dehumidification of indoor air 50A by swithcing over the passage by means of passage switching parts 31-34. In humidifying action, this makes the moisture absorbent part 81 of a rotating moisture absorber-desorber 80 absorb the moisture in outside air 11, and also this gives the absorbed moisture to indoor air 50A with a remaining heat moisture desorbing part 83 and a heating moisture desorbing part 82, and discharges it from a forced ventilation part 75. In dehumidifying action, this gives moisture in the indoor air 50A absorbed in the moisture absorber-desorber 80 to outside air and discharges it from a forced ventilation part 23, by switching the passages to outside air 11 and indoor air 50A thereby circulating it. The penetration work for a wall part 51 is simplified, by providing an external part 22 with the forced ventilation part 23, and circulating the outside air 11 into semicircular split passages 24A and 24B being made by splitting one conduit 24 or into split passages 24C and 24D in the shape of a dual circle thereby performing the suction and discharge. This can be constituted also as a humidistat for exclusive use in humidification or for exclusive use in dehumidification.
