Title: Dna gene
Inventor: TAMURA GAKUZOU
IPC: C07H21/04
Filed: 1981-10-20
Abstract: NEW MATERIAL:A DNA gene, derived from an alkaline phosphatase gene (phoA) of coliform bacillus (Escherichia coli), and having at least the promotor sequence, shine-Dalgarno sequence or signal sequence. USE:A gene capable of coding a desired peptide is joined to the downstream side of a phoA promotor, and the powerful development thereof is possible. The peptide can be secreted and produced in the form of a periplasm under the controlled concentration of the phosphoric acid in the culture medium. PROCESS:A strain of coliform bacillus (Escherichia coli) deficient in the cohesive site of phage lambda is infected with a phage to give a phage in which the phoA is transformed by the mixed lytic technique. The resultant phage and plasmid pBR322 are then double digested with the same restriction restriction enzyme, mixed and joined to obtain a plasmid pKI-2 in which the phoA is cloned. The pKI-2 and a vector DNA, e.g. pMC1403, are digested by a restriction enzyme and joined by a T4-ligase to give a plasmid pYK171 containing the phoA. The resultant plasmid pYK171 is then partially hydrolyzed and treated with SamI to afford the aimed plasmid YK190.

Title: Garbage treating apparatus
Inventor: NAKAMOTO MITSUYOSHI
IPC: F26B3/08
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To shorten the time from dumping garbage up to disposal of a treated garbage by heating a supply dry air but not mixing a combustion gas generated from a combustion heat generator within the dry air. SOLUTION: A high-temperature combustion gas 7 is generated by a burner 6 equipped within a combustion heat generator 5. This gas is heat exchanged by a heat exchanger, and then exhausted from a combustion gas exhaust port 8. A dry air supply unit 10 supplies a dry air 9 to a heat exchanger 4 by a fan 11. After the dry air is heated by a heat of the combustion gas, the air is introduced into a dry treating unit. When garbage 13 is dumped in the dry treating unit 2, a high-temperature dry air 9 is injected from an ejector 14, and supplied to the garbage. A motor 15 is connected to an agitator 12. When the motor 15 is rotated, the agitator 12 agitates the garbage, thereby accelerating drying of the dry garbage 13. Treated air 16 after the garbage is dry treated is exhausted from an exhausting unit 17.

Title: Semiconductor element envelop
Inventor: WAKAMATSU HIDEKI
IPC: H01L23/50
Filed: 1992-06-25
Abstract: PURPOSE:To obtain a high-reliability semiconductor envelop by improving the shape of the envelop comprising a sealing resin layer for embedding a semiconductor element, inner leads, outer leads, notches formed from sealing resin layer ends to inner side, and inner lead portions exposed at the notches. CONSTITUTION:An inner lead 8 is exposed at a notch 7 formed from a resin sealing layer end of an envelop 1 for semiconductor element toward the inner portion, an outer contactor 3 to be used for during evaluation process is contacted, thereby preventing the deformation of the outer lead 2 and reducing the contact resistance with the outer contactor 3.

Title: Method for attaching cooling parts and method for sealing module
Inventor: ARAI NATSUO
IPC: H01L23/40
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To improve cooling efficiency of electronic components by radiating the heat generated from the electronic components through cooling parts by reducing the volumes of voids in solder by fixing the electronic components and cooling parts to each other in a pressurizing atmosphere, in a state where the electronic parts and cooling parts are brought into contact with each other via molten solder, and then returning the parts to the atmosphere. SOLUTION: At attaching of cooling parts 100 to electronic components 106 mounted on a substrate 104 by soldering, the parts 106 and 100 are brought into contact with each other via molten solder 110 and 112 and fixed to each other in a pressurizing atmosphere, and then the parts 106 and 100 are returned to the atmosphere. Since the solder 110 and 112 are in molten states in the pressurizing atmosphere, when the parts 100 are attached to the parts 106 in this way, the pressure in a chamber becomes higher than the pressure of helium gas enclosed in the solder 110 and 112, even if the helium gas is enclosed in the solder 110 and 112. Therefore, the sizes of voids formed in the solder 110 and 112 can be reduced, because the helium gas enclosed in the solder 110 and 112 is crushed out, due to the pressure difference between the pressure in the chamber and that of the gas.

Filed: 1994-07-20
Abstract: PURPOSE:To improve the display contrast by adhering the entire front opening part of a case with a translucent colored color filter and providing a mask plate with a color tone in complementary color relation with the color filter between the reverse side of the color filter and a luminous displaying element. CONSTITUTION:On the reflection path of external light, the external light which is transmitted through the color filter 13 is reflected on the top surface of the mask plate 16. Its reflected light is transmitted through the color filter 13 again and reflected to the outside, but the light is not reflected by the mask plate 16 because the color filter 13 and mask plate 16 are in the complementary color relation, so that the top surface part of the mask plate 16 provides a black display. Further, only the colored light which is transmitted through the color filter 13 reaches the display part of the liquid crystal display element 14 and its reflected light is transmitted through the color filter 13 again, so the reflected light decreases in quantity since it is transmitted through the color filter 13 twice, so that the display contrast becomes excellent.
