Inventor: YAMAUCHI HIROSHI
IPC: B09B3/00
Filed: 1994-02-22
Abstract: PURPOSE:To obtain a solidifying agent which has good uniform-dispersibility into surplus soils such as slurried excavation surplus soil, etc., and is lightweight by forming the agent through blending respective prescribed pts.wt. of an aqueous polymer and a powdery natural organic substance together. CONSTITUTION:This agent is formed by blending 100 pts.wt. of an aqueous polymer and 10 to 1000pts.wt. of a powdery natural organic substance together. Such combination of the aqueous polymer and the powdery natural organic substance is appropriately selected from respective groups of water-absorbing resins, water-soluble polymers and powdery natural organic substances without imposing any particular limitation on the selection. Also, by blending the natural organic substance, the aqueous polymer is easily and uniformly dispersed into slurries. Further, since the powdery natural organic substance contains many hydrophilic groups such as hydroxyl or carboxyl group, etc., the substance has very good affinity for both the aqueous polymer and slurries. Therefore, this solidifying agent shows good dispersibility into slurries and excellent performances as solidifying agent for treating surplus soils.

Title: Reproducing circuit of digital signal
Inventor: HORIGOME JIYUNICHI
IPC: G11B20/10
Filed: 1984-03-15
Abstract: PURPOSE:To prevent generation of a transient state without losing a low frequency component of a reproducing signal by providing a switching means controlled by a control signal so that a time constant including a coupling capacitor is increased more after a nearly transient period from a point of time when the period is switched from a period with no digital reproducing signal into a period having the said signal. CONSTITUTION:A band pass filter 10, an envelope detection circuit 11, a comparator 12 and a delay circuit 14 constitute a detection circuit detecting the presence or absence of the digital reproducing signal from an input terminal 1. A detected output as shown in Fig. B is generated from the envelope detection circuit 11 in response to the digital reproducing signal as shown in Fig. A. When the detected output is given through the comparator 12 and the delay circuit 14, a control signal as shown in Fig. C is formed and this control signal is fed to a switching circuit 7. When the control signal is at high level, the switching circuit 8 is turned on and when the control signal is at low level, the switching circuit 7 is turned off. Thus, the switching circuit is turned from on to off after a time T from the point of time when the period is switched from a period without any digital reproducing signal to a period having it in case of the control signal as shown in Fig. C.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain a white light emitting element and a white light source device using this light emitting element by connecting emitted luminous flux to an optical fiber end surface efficiently. SOLUTION: An underclad layer 2 is formed by an SiO2 thin film on a light wave directing path board 1. Si-Cr target material is sputtered in an oxygen atmosphere, an SiO2 film 3 comprizing CrO2 is formed on the surface of the underclad layer 2, and a core portion 4 is formed by leaving its part behind. An overclad layer 5 is formed on the surface of the underclad layer 2 and the core portion 4 by an SiO2 film, and made into a light wave directing path 6. It is presumed that concentration quenching is hard to occur even if chromium ions are added to quartz glass to a high concentration, since the ion radius of a quadrivalent cation of chromium is in the same extent as that of a quadrivalent cation of silicon.  Accordingly, it is possible to constitute a light wave directing path type light source capable of producing a practically sufficient quantity of light, having excellent spatial coherence, and being a solid medium capable of connecting emitted luminous flux to the end surface of an optical fiber efficiently.
