Title: Polypeptide and production thereof
Inventor: FUJISAWA YUKIO
IPC: C07K14/705
Filed: 1988-12-15
Abstract: PURPOSE:To enable mass production of ingredient vaccine for herpes simplex virus(HSV) by using a recombinant DNA containing a base sequence capable of coding a surface protein gD of HSV-1 MIYAMA strain. CONSTITUTION:A DNA capable of coding a polypeptide containing an amino acid sequence expressed by the formula is used to form a recombinant DNA, which is then used to transform a host. The resultant transformed host is subsequently cultured to afford a large amount of the polypeptide expressed by the formula. The recombinant DNA is obtained by separating a genomic DNA from an HSV-1 type MIYAMA strain, digesting the DNA with a restriction enzyme BamHI and integrating the obtained digest into a plasmid replicable in Escherichia coli. The resultant recombinant plasmid is used to transform the host Escherichia coli. The obtained transformant is cultured and a plasmid containing the objective DNA can be isolated by a colony hybridization method, etc., to provide the objective polypeptide.

IPC: H01J9/02
Filed: 1989-12-07
Abstract: PURPOSE:To easily obtain a spacer having a high aspect ratio and a rectangular section by creating grooves on a resist film for burying dielectric powder for being baked. CONSTITUTION:A photoresist layer 4 provided at least with patterns in the shape of grooves 4a on a board 3 are formed and the grooves 4a of the photoresist layer 4 are filled with dielectric powder 5.

Abstract: PURPOSE:To prevent dewing by generated steam by positioning a pressure member above a nip part and a heater and a fixing film below the nip part. CONSTITUTION:A recording material P in a cassette S is picked up by a feed roller 7 to pass through a sensor 10, and by synchronizing with a signal of this passing, a picture is started drown on a sensitized drum 4 by a laser light emitting device 3.

Filed: 1989-12-08
Abstract: PURPOSE:To enable formation of a desired function output by providing adequately the shape of a gap zone between the drain-side end part of a gate electrode and the gate-electrode-side end part of a drain region and the width thereof in the direction of a channel. CONSTITUTION:An n-type substrate 1 being used, a source region 2 and a drain region 3 which are of P type are formed by diffusion of boron and thereby a p-n junction and a depletion layer 8 are formed at the peripheral edge of the drain region being in contact with an n-type region. The drain-side end part of a gate electrode 5 is formed in a stepped shape so that it approaches the drain region 3 sequentially along the direction intersecting a channel perpendicularly. A stepped part 5a alone overlaps the drain region 3 with an insulating layer 4 interposed therebetween, while the other two stepped parts 5b and 5c are so formed as not to overlap the drain region, and thus a gap zone 13 is formed. Accordingly, a channel width increases gradually as a drain voltage increases gradually, and consequently a drain current increases. By setting the shape of a gap and the impurity concentration of the substrate adequately, according to this constitution, output characteristics in the form of a desired function can be obtained.
