Title: Selective hydrogenation of ester compound having acetylenic unsaturated bond
Inventor: KINOSHITA SHIYOUICHI
IPC: B01J23/00
Filed: 1978-09-08
Abstract: PURPOSE: To prepare a compound having an ethylenic unsaturated bond, in high purity, by hydrogenating an ester compound having an acetylenic unsaturated bond using a reusable selective hydrogenation catalyst obtained by oxidizing a Pd catalyst containing a tin salt.  
     CONSTITUTION: A compound having an ethylenic unsaturated bond (e.g. linalyl acetate) is prepared by the catalytic hydrogenation of an ester compound having one or more acetylenic unsaturated bonds (e.g. dehydrolinaly acetate) in the presence of a catalyst obtained by the oxidation of a Pd catalyst containing a tin salt. The amount of the tin salt is 0.1W20 parts by weight per 1 part of Pd. The precess is especially effective to produce the terpene compound having a tertiary ester.

Inventor: NISHI TOYOTA
IPC: H04L27/00
Filed: 1990-04-27
Abstract: PURPOSE:To accurately estimate a bit error ratio even in measurement for several seconds by measuring the level value of a demodulated analog waveform signal at the clock timing of a digital signal and estimating the bit error ratio from relation between the mean value of plural level values and the measured value. CONSTITUTION:This monitoring system is provided with a means 9 for measuring the level value of an analog wave signal obtained by demodulating a receiving signal on the receiving side at the clock timing of a digital signal and a means 19 for estimating a bit error ratio from the relation between the mean value of plural level values found by the means 9 and a measured value. In this case, the absolute value of a difference between an instantaneous analog demodulation output value at an identification timing based upon a recovered clock in the digital decision process of each bit of the demodulated output and the mean value calculated based upon several past analog demodulation output values is monitored. Consequently, receiving quality for a short period such as several seconds can be accurately estimated in service.

Filed: 1986-05-14
Abstract: PURPOSE:To simply perform a sealing operation at low cost by a method wherein the mold having the mirror face consisting of the material non-adhesive to the poured transparent resin covering a photoelectric conversion element is positioned in such a manner that the mirror face is pushed against and comes in contact with the photo signal incident plane of the transparent resin, and the mold is exfoliated after the resin has been hardened. CONSTITUTION:The photoelectric conversion element 1 of an insulating substrate 6 is wire-bonded by performing a wire-bonding, and transparent resin 7 is poured on the photoelectric conversion element 1 until a wire 8 will be completely hidden using a dispenser and the like. Then, the spacer 9 is placed on the substrate 6 in such a manner that it does not come in contact with the transparent resin, and when the mold 11 having the mirror face 10, consisting of the material which is non-adhesive to the transparent resin 7, is placed on the spacer 9 in such a manner that the mirror face 10 comes in contact with the transparent resin 7, the transparent resin 7 is tightly adhered to the mirror face 10 by surface tension. Then, the transparent resin 7 is hardened, and when the mold 11 and the spacer 9 are removed, the photosignal incident plane 12 of the transparent resin 7 is turned to the state of mirror face. Accordingly, the photoelectric conversion element 1 can be simply sealed at low cost without using glass.
