[KODERA YOSHIE, TSUKAHARA MASAYUKI, KANEKO KAZUO, NAKA REIJI] PURPOSE:To mold the harmonious low-density formed body having no unequal section by increasing high-frequency energy supplied to a foaming reactive substance with the advance of a foaming reaction from the initial stage of the reaction. CONSTITUTION:The foaming reactive substance 2 consisting of polyol, polyisocyanate, etc. is injected into an aluminum pan 1A for foaming molding. Electricity is inputted to a high-frequency power supply 3, and the high-frequency energy of 2.45G Hz is increased monotonously while being controlled by means of a controller 9 up to t1=60sec. where the quantity of the reaction is maximized. The foam density of hard polyurethane foam obtained is 22Kg/m<3>, and the foam is uniform.

[IBA YOSHITAKA, YASUKAWA KIYOSHI, KANEKO TAKASHI, TAKAGI KUNIAKI, KANAKI REIJI] PURPOSE: To obtain gene fragments coding for the V-regions of a H-chain and a L- chain of an antibody recognizing a mucin-type synthetic glycolipid, having specific base sequences and capable of efficiently producing an antibody against a cancer- specific sugar chain, which is useful as the treating agent, diagnostic, etc., of cancer. CONSTITUTION: Mouse is immunized with a mucin-type synthetic glycolipid (F1α antigen) and B-cells are collected from the mouse. The B-cell is fused with a mouse bone marrow cell to prepare F1α 75 hybridoma. An mRNA is extracted from the hybridoma and a cDNA is prepared from the mRNA by an ordinary method. Polymelase chain reaction(PCR) is carried out using a template of the obtained cDNA and a probe of each of a partial base sequence of the V-region of the H-chain and the V-region of the L-chain of the antibody. Thus, a DNA coding for the V-region of the H-chain and that of the L-chain of the antibody are separately multiplied to obtain the objective gene fragments coding for the V-region of H-chain of the antibody recognizing F1α and containing the base sequence of formula I, and that coding for the V-region of L-chain of the antibody recognizing F1α and containing the base sequence of formula II.

[IIMORI TAKESHI, KANEKO REIJI, YOSHIKAWA HIROSHI, MACHIDA MAKOTO] PURPOSE:To provide the subject new strain having high lignindegradative activity, etc., thus capable of bleaching pulp dispensing with a chlorine-based chemical. CONSTITUTION:The objective microbe SKB-1152 strain (FERM P-13721) having high lignin-degradative activity and high-temperature pulp-bleaching activity. It is preferable that pulp be bleached by treating pulp using the above microbes or a cultured product obtained by using said microbes followed by alkali treatment.

[Yoshinori Murakami, Reiji Abe, Tadashi Matsuhira, Yoshiro Oishi, Hiroaki Mochizuki, Hajime Fukushima, Hiroomi Kuribayashi, Akito Kaneko] JP Tokyo A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.

[Minami Toshiaki(Tokyo,JPX), Fukuchi Tadakazu(Tokyo,JPX), Ohashi Reiji(Tokyo,JPX), Kaneko Toshio(Tokyo,JPX)] A heat-sensitive recording sheet has on a support a color-developing layer which comprises a colorless or pale colored basic chromogenic dye and an organic color-developing agent, wherein the organic color-developing agent comprises both 4-hydroxy-4'-n-propoxydiphenylsulfone and a particular phenolic substance. The sheet of this invention provides excellent writing quality and superior thermal responsibility.

[KAWASAKI SHUICHI, NANRI YASUTOKU, KANEKO REIJI, MACHIDA MAKOTO] PURPOSE:To obtain base paper for an electrically insulating laminated sheet good in dimensional stability by forming paper from bleached pulp in which the microbial treatment is integrated into a step before or after chlorine-free bleaching treatment. CONSTITUTION:This base paper for a laminated sheet is obtained by forming paper from bleached pulp as a raw material prepared by integrating the microbial treatment with a lignin decomposing enzyme or a hemicellulose decomposing enzyme into a step before or after chlorine-free bleaching treatment selected from treatments with oxygen and an alkali, ozone, hydrogen peroxide or an enzyme or plural combined treatments thereof. The resultant base paper is then impregnated with an alcohol-soluble phenolic resin and dried to provide prepreg sheets. A prescribed number of the prepreg sheets are subsequently laminated and subjected to the hot-pressing treatment to afford the electrically insulating laminated sheet composed of the synthetic resin-impregnated paper substrate.

[KANEKO AIJIROU, KOJIYOU REIJI] ;

[KANEKO REIJI, NAKAGAWA KAZUTAKA] PURPOSE:To produce a base paper for laminated board having improved low- temperature punchability, electrical characteristics and heat-resistance while keeping dimensional stability. CONSTITUTION:A base paper for a laminated board is produced by using a pulp having a hemicellulose content of <=20% and a fiber flexibility of <=15 and obtained by including a specific enzymatic treatment in the bleaching process of an unbleached pulp having a kappa number of 12-26.

[IIMORI TAKESHI, KANEKO REIJI, YOSHIKAWA HIROSHI, MACHIDA MAKOTO] A method of bleaching pulp using a microbe SKB-1152 strain, which is a lignin-decomposing bacterium having a high lignin-decomposing activity and a high activity of hightemperature pulp bleaching, or a product of culturing the microbe. The above method can be performed by the conventional biobleaching process without the necessity for employing special culture conditions. This strain can be obtained from a declorated zone formed in the medium prepared by inoculating a sample strain in a medium containing lignin and/or pulp wherein lignin remains.
