Abstract: PURPOSE:To maintain necessary mechanical strength for a specified period of time as well as to allow propagated cells to come inside with ease with affinity for cells and tissues maintained excellent by letting collagen with cross- linking structure be composed of denatured collagen processed with heat under the presence of water. CONSTITUTION:Denatured collagen can be obtained in such a way that collagen derived from true cow skin is oxidized or alkalized so as to let obtained collagen including triple chain helices be processed with heat or with cross-linking agent applied for letting the processed one be heated upto 50 to 125 deg.C under the presence of water thereafter. As raw collagen, oxidized or alkalized one with no antigen property is preferable wherein telopeptide at its molecular end is digested so as to be removed by use of proctase or pepsine. The cross- linking of collagen is preferably processed in such a way that it is kept at 110 deg.C under vacuum for the period of time equal to or more than 24 hours so as to be dehydrated when it is processed by cross lining treatment. And cross-linking agent in an aldehyde family such as glutaric aldehyde and the like is used at the time of processing by use of cross-linking agent.

Title: Detecting circuit of infrared-rays
Inventor: HAMA RITSUO
IPC: G01J5/14
Filed: 1982-03-31
Abstract: PURPOSE:To prevent the generation of error signals due to popcorn noise, by combining two pyroelectric infrared-ray detectors with a gate circuit. CONSTITUTION:The pyroelectric infrared-ray detectors 24, 25 are adjacently arranged in parallel so as to detect infrared-rays from the same irradiating body simultaneously. The outputs of both the detectors are applied to a gate circuit 34 consisting of a transistor 35 and a bias resistor 36 through respective amplifiers 30, 31. Subsequently, an output from the gate circuit 34 is applied to a control circuit 37. Since both the detectors 24, 25 do not generate popcorn noises simultaneously, a noise is gated by the gate circuit 34 and prevented from being supplied to the control circuit 37 even if the noise is generated in the detector 24. Thus the generation of error signals due to the popcorn noises can be prevented.

Abstract: PURPOSE:To obtain a variable tuning width of a large selection wavelength by forming both end faces of an element which is disposed with plural distributed feedback regions having phase shift structure and active regions in series and are coupled optically into non-reflection structure. CONSTITUTION:A lambda/4 shift diffraction grating is formed to the distributed feedback regions 201, 202 on an n-type InP substrate 110. After an InP clad layer 150 and active layer 140 of the regions 201, 202 are selectively removed, a p-type InP clad layer 160 is formed over the entire part. Grooves for electrical sepn. of amplifier regions 101, 102 and the regions 201, 202 are formed by executing mesa etching followed by embedment growth. An SiN film 170 is thereafter formed in order to decrease the reflectivity at both end faces of the element to <=1%. The oscillation of the element as a distributed feedback type laser is caused unless both end faces 170 have the nonreflection structure. Addition of the transmission prohibition wavelength region of the 2nd distributed feedback regions to the wavelength regions where the prohibition is heretofore not possible with the single distributed feedback region alone is thereby permitted and the wavelength selection width is increased.
