Inventor: KNISKERN PETER J
IPC: C07K1/22
Filed: 1992-04-27
Abstract: TITLE OF THE INVENTION HEPATITIS B VIRUS SURFACE PROTEINS WITH REDUCED HOST CARBOUYDRATE CONTENT            ABSTRACT OF THE INVENTION     In order to produce hepatitis B virus (HBV) surface proteins in the form of particles with substantially reduced entrapped carbohydrate content, DNA encoding the B V surface proteins was expressed in a recombinant yeast host which is deficient in its ability to glycosylate proteins.  These BBV surface proteins display the antigenic sites genetically encoded by the S domain of the HBV virion envelope open reading frame and contains substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in "wild-type" yeast cells. These particles are useful as a vaccine for both the active and passive treatment or prevention of disease and/or infection caused by HBV or other agents serologically related to HBV.

Title: Tape printing device
Inventor: NUNOKAWA MASAHIKO
IPC: B41J5/30
Filed: 1993-10-05
Abstract: ABSTRACT OF THE DISCLOSURE    The  present  invention  provides  an  improved  tape printing device for printing a desirable series of characters in a preferable balance on a tape through a simple operation. The tape printing device of  the  invention  is used for printing text data in a plurality of lines along a width of the  tape  and  in  a  plurality  of  'paragraphs'  along  a predetermined length of the tape.   The 'paragraph' in the tape printing device is different from a paragraph in a word processor and includes a fixed number of lines.  Even when text data in a certain line of a paragraph is deleted, the certain line is kept in the paragraph as a vacant line. In another application,  the tape printing device of the invention includes a predetermined menu for printing text data in a plurality of lines.  The plurality of lines are arranged in a good balance when the user selects one of possible  choices  for  each  required  information  in  the predetermined menu.    Since  these  possible  choices  are automatically varied according to the width of the tape, the user can obtain a label with rows of characters printed in a preferable balance, without setting required information according to each tape width.  The invention also provides a novel technique for displaying a distinct printing image and improves printing with a shade pattern and creation of a foreign character.
