摘要:
This invention provides a means for enabling high-level secretory production of proteins, in particular proteins having complicated structures such as antibodies, in host cells such as yeast cells. The invention also provides transformed yeast cells having the activated HAC1 gene and the RRBP1 gene and a method for enabling high-level secretory production of foreign proteins using such transformed host cells by inhibiting O-sugar chain formation indigenous to host cells such as yeast cells.

A piezoelectric material layer is easily formed on a partial region of the substrate surface. By forming a different hardness material layer that has a different hardness from that of the substrate in the form of a pattern on the surface of the substrate, a film-deposition permitting region A to which particles of a piezoelectric material in a carrier gas adhere in a form of a film and a film-deposition inhibiting region B which inhibits the formation of a film are provided. Further, when a carrier gas containing particles of a piezoelectric material are ejected onto the surface of the substrate by means of AD, a film-like piezoelectric material layer is formed as a result of the adhesion of the particles in the film-deposition permitting region A. As a result, the piezoelectric material layer can be formed easily in a partial region of the surface of the substrate.

The present invention relates to a means for generating a mucin-type glycopeptide or glycoprotein on a large scale in yeast. Specifically, the invention relates to a method which comprises introducing into a yeast at least one selected from the group consisting of a gene encoding UDP-GalNAc synthetase, a gene encoding UDP-GalNAc transporter, and a gene encoding polypeptide:O-GalNAc transferase, and, if desired, a gene encoding a mucin-type glycopeptide; and producing a mucin-type glycoprotein having O-GalNAc by use of the yeast.

A semiconductor chip mounted interposer (60) is configured by executing wire bonding between a semiconductor chip (50) and an interposer (20), in which terminals (21) that connect to terminals (51) of the chip (50) and separate terminals (22) are formed, on the upper face of the interposer (20). A semiconductor chip (30) is mounted to the top face of a package substrate (10), the interposer (60) is adhered to the upper portion of the chip (30), and wire bonding is executed between the terminals (22) and terminals (11′). When configuring a semiconductor device with a plurality of semiconductor chips combined into one package in this manner, KGD (Known-Good-Die) can easily be guaranteed for each semiconductor chip, and semiconductor devices can be fabricated with a high yield of good units. Also, the semiconductor chips can be used as-is, without restricting the position, pitch, signal arrangement, or the like, of their terminals.

An ink-jet head includes a channel unit which includes a plurality of pressure chambers, a vibration plate stacked on the channel unit, and a piezoelectric material layer arranged on the vibration plate. The piezoelectric material layer includes a first portion functioning as a piezoelectric actuator, and a second portion functioning as a piezoelectric transformer which amplifies a driving signal to be supplied to the piezoelectric actuator. Accordingly, it is possible to realize a small-size ink-jet head with a built-in piezoelectric amplifier.

A method of manufacturing an ink jet printing head includes: forming a first laminated structure by laminating at least two metal plates having a hole formed thereon and fixing the metal plates to one another by metal-metal junction, and by laminating a plurality of thin plate members having a hole formed thereon, the thin plate members including the metal plates, and fixing the thin plate members to one another; forming a second laminated structure that includes at least a part of a common ink chamber, by laminating a plurality of thin plate members having a hole formed thereon and fixing the thin plate members to one another; and fixing the first laminated structure and the second laminated structure to each other while laminating the first laminated structure and the second laminated structure on each other.
摘要:
Ultra-fine particles are jetted from a nozzle to be deposited on a substrate via a mask which is plate-shaped and in which an opening pattern is formed, thereby forming on the substrate a thin film having a shape corresponding to the opening pattern. The mask has a first area, a second area which surrounds the first area and defines an opening between the first area and the second area, and a bridge portion connecting the first and second areas. The bridge portion is formed at a position away from the bottom surface of the mask. By using this mask, a thin film having a pattern including an independent non-film formation area can be formed.
